Java monitoring tools

Java monitoring tools

There are a few tools you can use to monitor and identify performance inhibitors in your Java™ applications.

vmstat: Provides information about various system resources. It reports statistics on kernel threads in the run queue as well as in the wait queue, memory usage, paging space, disk I/O, interrupts, system calls, context switches, and CPU activity.
iostat: Reports detailed disk I/O information.
topas: Reports CPU, network, disk I/O, Workload Manager and process activity.
tprof: Profiles the application to pinpoint any hot routines or methods, which can be considered performance problems.
ps -mo THREAD: Shows to which CPU a process or thread is bound.
Java profilers [-Xrunhprof, Xrunjpa64]: Determines which routines or methods are the most heavily used.
java -verbose:gc: Checks the impact of garbage collection on your application. It reports total time spent doing garbage collection, average time per garbage collection, average memory collected per garbage collection, and average objects collected per garbage collection.

Here are 10 tools useful for Java application performance troubleshooting.

jconsole comes together with JDK 1.5 and above. It is a Java Monitoring and Management Console - JMX-compliant graphical tool for monitoring a Java virtual machine. It can monitor both local and remote JVMs.

VisualVM is a visual tool that integrates several existing JDK software tools and lightweight memory and CPU profiling capabilities. This tool is designed for both production and development time use and further enhances the capability of monitoring and performance analysis for the Java SE platform.

HeapAnalyzer allows the finding of a possible Java™ heap leak area through its heuristic search engine and analysis of the JavaTM heap dump in Java applications. It analyzes Java heap dumps by parsing the Java heap dump, creating directional graphs, transforming them into directional trees, and executing the heuristic search engine.

PerfAnal is a GUI-based tool for analyzing the performance of applications on the Java 2 Platform. You can use PerfAnal to identify performance problems in your code and locate code that needs tuning.

JAMon is a free, simple, high performance, thread safe, Java API that allows developers to easily monitor production applications.

Eclipse Memory Analyzer is a fast and feature-rich Java heap analyzer that helps you find memory leaks and reduce memory consumption.

GCViewer is a free open source tool to visualize data produced by the Java VM options -verbose:gc and -Xloggc:<file>. It also calculates garbage collection related performance metrics (throughput, accumulated pauses, longest pause, etc.).

WASServiceCmd utility

2011-04-06T23:30:00.002+05:30

I faced lot of issues with WebSphere services on Windows 2008 R2 64bit boxes.
WASService adds the WAS Services to Windows services list, but fails to stop/start them.

If I bounce the box, then services are getting started. If I stop them, it is setting the service status as blank. If I start it again, it throws "Windows could not start IBM WebSphere Application Server – servicename on local computer". When checked in the event logs "The IBM WebSphere Application Server V7.0 - CellManager01 service terminated with service-specific error %%134220456." is the message.

This is how I have added WAS Services to Windows Services

D:\IBM\WebSphere\AppServer\bin\WASService.exe -add CellManager01 -serverName dmgr -profilePath D:\IBM\WebSphere\AppServer\profiles\Dmgr01 -wasHome D:\IBM\WebSphere\AppServer -logFile D:\IBM\WebSphere\AppServer\profiles\Dmgr01\logs\dmgr\SystemOut.log -logRoot D:\IBM\WebSphere\AppServer\profiles\Dmgr01\logs\dmgr -restart true -startType automatic -stopArgs "-username xxxxxxxxx -password xxxxxxx" –encodeParams

To solve this, one can use WASServiceCmd Utility. This utility is easy to use, grabs all the info you need to pass, creates the service command, executes it.

Here is the technote about WASServiceCmd

http://www-01.ibm.com/support/docview.wss?rs=180&uid=swg21397335

Here is my WASServiceCmd log entry
wasservice.exe -add "CellManager01" -serverName "dmgr" -profilePath "D:\IBM\WebSphere\AppServer\profiles\Dmgr01" -encodeParams -stopArgs "-username xxxxxxxx -password ******** -startType automatic -restart true
wasservice.exe -add "Node01" -serverName "nodeagent" -profilePath "D:\IBM\WebSphere\AppServer\profiles\wlmprime01" -encodeParams -stopArgs "-username xxxxxxx -password ******** -startType automatic -restart true

These services are now, properly working.

Elevated user privileges

2011-03-28T21:47:00.001+05:30

Problem: I have edited a file, say, httpd.conf on Windows 2008 R2 64 bit server. I saved the file and bounced the apache. But, my changes were not in effect. I looked deep into it, then realized that, Windows is storing a copy of httpd.conf on Desktop in VirtualData folder, under this folder, created entire folder structure and stored the file in there.
To avoid this, edit the files or run the commands as an administrator or disable User Access Control (UAC).

Technote from IBM

Running WebSphere Application Server command-line tools might require elevated Microsoft Windows user account privileges

Technote (troubleshooting)

Problem(Abstract)

To successfully use some IBM WebSphere Application Server command-line tools, you might need to explicitly elevate Microsoft Windows user account privileges if you are not using the built-in administrator account to run the commands. This action is applicable to the Windows 7, Windows Vista, Windows Server 2008 R2, and Windows Server 2008 operating systems only.

If Windows User Account Control (UAC) is disabled on your system, then this document is not applicable.

Cause

You must use a Windows user account that has full Administrator account privileges for certain operations on Windows 7, Windows Vista, Windows Server 2008 R2, and Windows Server 2008 operating systems. Commands that involve Windows services or access to the Windows system registry require that type of full authority due to the Windows User Account Control implementation for those two operating systems.

For example, if you use a regular administrator group account that is not the built-in Administrator account, then you will likely need to explicitly elevate your user account privileges when you run the launchpad or Profile management tool commands. This action assumes that your operating system is running with the default values for system-wide security policies that are related to the Windows User Account Control.

Proxy Error Bad Gateway

2011-01-20T23:34:00.001+05:30

InfoCenter is down.

To understand whats wrong - Proxy error, bad gateway etc, this is a temp state. Upstream server response is broken and so the message.

502 Bad Gateway: The server was acting as a gateway or proxy and received an invalid response from the upstream server.^[2]
503 Service Unavailable: The server is currently unavailable (because it is overloaded or down for maintenance).^[2] Generally, this is a temporary state.
504 Gateway Timeout: The server was acting as a gateway or proxy and did not receive a timely response from the upstream server.^[2]

Xms!=Xmx

2010-12-20T21:44:00.002+05:30

Setting the initial Java heap minimum equal to the Java heap maximum is not recommended. Doing so can delay the start of garbage collection until the heap is full. Therefore, the first time the Garbage Collector runs is a very expensive operation.
The heap is also likely to be very fragmented by the time heap compaction is required. This is also a very expensive operation.

recycle logs

2010-09-25T02:58:00.002+05:30

To recycle JVM Logs [a.k.a SystemOut.log and SystemErr.log] -
We have separate log slice for SystemOut and SystemErr. Whenever I bounce the server, I try to clear the logs, take a backup of the logs in a folder with time and date stamp for reference. I may hold such historical backup of the logs for say two months.
Here is a batch script to create a folder with todays date and time stamp, move the files into that folder.

@echo off
@REM This script is to recycle the jvm logs

@REM To recycle
@REM 1. set the log home
set jvm_log_home="<YOUR_LOG_HOME>"
set log_bak_home="<YOUR_LOG_BACKUP_HOME"
@REM 2. Set Date variable
set today=%date:~4,2%-%date:~7,2%%date:~10,4%%time:~0,2%%time:~3,2%%time:~6,2%%
@REM 3. create a folder with date stamp
mkdir %log_bak_home%\%today%
@REM 3. move the logs to that folder
move %jvm_log_home%\*.* %log_bak_home%\%today%

Whenever I bounce the server, I try to cleanup the cache too. Here is the script to clean up the cache.
Here is the batch script to clean the cache -

@echo off
@REM This script is to recycle the temp/cache on the local server
@REM To cleanup the cache
@REM 1. goto profile home temp
set profile_temp_home="<YOUR_PROFILEHOME_TEMP_NODE"
echo "profile path=%profile_temp_home%"
@REM 2. goto servername
set server_name="<YOUR_SERVER_NAME"
@REM 3. delete all under servername
echo "here i am %profile_temp_home%"
FOR /D %%i IN (%profile_temp_home%\%server_name%\*) DO (
@REM echo %%i
rmdir /S /Q "%%i"
)

[mqm@localhost ~]$ /opt/mqm/samp/bin/amqsput QL.A
Sample AMQSPUT0 start
target queue is QL.A
bhaskar is the name of the this person
u know if u dont know you better know

[mqm@localhost ~]$ /opt/mqm/samp/bin/amqsput QA.A
Sample AMQSPUT0 start
target queue is QA.A
do you really want to test the alias queues
MQPUT ended with reason code 2051

The thing here is
We have an alias queue per local queue. QA.A is alias for QL.A and QA.B is the alias for QL.B.
ALTER QA(QA.A) PUT(DISABLED)
This disabled PUT on QA.A
Alias has muted PUT.

ALTER QL(QL.B) PUT(DISABLED)
This muted the PUT on local queue itself.

Working with queues
__ 1. Put some messages on your queues QL.A and QL.B.

On QL.B, put is disabled above. So, reset it to enable
ALTER QL(QL.B) PUT (ENABLE)
1 : ALTER QL(QL.B) PUT (ENABLE)
AMQ8405: Syntax error detected at or near end of command segment below:-
ALTER QL(QL.B) PUT (E

AMQ8427: Valid syntax for the MQSC command:

[mqm@localhost ~]$ /opt/mqm/samp/bin/amqsput QL.B
Sample AMQSPUT0 start
target queue is QL.B
blah blah QL.B blah blah
its working now enable and enabled...awesome difference

__ 2. Show the CURDEPTH of all the queues you have created.
• DISPLAY Q(Q*) CURDEPTH
DISPLAY Q(Q*) CURDEPTH
1 : DISPLAY Q(Q*) CURDEPTH
AMQ8409: Display Queue details.
QUEUE(QA.A) TYPE(QALIAS)
AMQ8409: Display Queue details.

QUEUE(QL.A) TYPE(QLOCAL)
CURDEPTH(6)
AMQ8409: Display Queue details.
QUEUE(QL.B) TYPE(QLOCAL)
CURDEPTH(2)

__ 3. Define an new local queue QL.X with the attributes of QA.A
• DEFINE QLOCAL(QL.X) LIKE(QA.A)
DEFINE QLOCAL(QL.X) LIKE (QA.A)
2 : DEFINE QLOCAL(QL.X) LIKE (QA.A)
AMQ8138: The WebSphere MQ queue has an incorrect type.

That says, one cannot create a queue like an alias

__ 4. Error? Now use the attributes of QL.A.
• DEFINE QLOCAL(QL.X) LIKE(QL.A)

DEFINE QL(QL.X) LIKE (QL.A)
3 : DEFINE QL(QL.X) LIKE (QL.A)
AMQ8006: WebSphere MQ queue created.

__ 5. Put some messages on QL.X.
• amqsput QL.X
[mqm@localhost ~]$ /opt/mqm/samp/bin/amqsput QL.X
Sample AMQSPUT0 start
target queue is QL.X
Here is my new queue buddy QL.X
Let me test this guy out

__ 6. Change the description of QL.A.
• ALTER QL(QL.A) DESCR('QL.A Text new')
ALTER QL(QL.A) DESCR('QL.A Text new')
4 : ALTER QL(QL.A) DESCR('QL.A Text new')
AMQ8008: WebSphere MQ queue changed.

__ 7. Display the DESCR attribute of all your queues.
• DISPLAY Q(Q*) DESCR

__ 8. Any change?
QL.X has QL.A's description
QL.A has new description

__ 9. Clear queue QL.A
• CLEAR QL(QL.A)
CLEAR QL(QL.A)
6 : CLEAR QL(QL.A)
DISPLAY Q(QL.A) CURDEPTH
7 : DISPLAY Q(QL.A) CURDEPTH
AMQ8409: Display Queue details.
QUEUE(QL.A) TYPE(QLOCAL)
CURDEPTH(0)

AMQ8022: WebSphere MQ queue cleared.
__ 10. Clear queue QA.A
• CLEAR QA(QA.A)

CLEAR QA(QA.A)
11 : CLEAR QA(QA.A)
AMQ8405: Syntax error detected at or near end of command segment below:-
CLEAR QA

AMQ8426: Valid MQSC commands are:

CLEAR QLOCAL

__ 11. Successfully? Give the reason why.

Means that you cannot clear an alias queue. Makes sense, alias queue is just a pointer to a queue, it does not hold any info in it.

__ 12. Delete QL.X
• DELETE QL(QL.X)

DELETE QL(QL.X)
12 : DELETE QL(QL.X)
AMQ8143: WebSphere MQ queue not empty.

Lets see the depth of the QL.X

DISPLAY Q(QL.X) CURDEPTH
13 : DISPLAY Q(QL.X) CURDEPTH
AMQ8409: Display Queue details.
QUEUE(QL.X) TYPE(QLOCAL)
CURDEPTH(2)

So one cannot delete an non empty queue

__ 13. Successfully deleted? If not, modify the command
• DELETE QL(QL.X) purge

DELETE QL(QL.X) purge
14 : DELETE QL(QL.X) purge
AMQ8007: WebSphere MQ queue deleted.

3. Once QM starts, create local queues using script.
Use the control commands interactively
Use the control command runmqsc to perform the following tasks. Enter all the
WebSphere MQ commands interactively and display the results at the terminal.

[mqm@localhost errors]$ runmqsc
5724-H72 (C) Copyright IBM Corp. 1994, 2005. ALL RIGHTS RESERVED.
AMQ8146: WebSphere MQ queue manager not available.

No MQSC commands read.
No commands have a syntax error.
All valid MQSC commands were processed.
[mqm@localhost errors]$

As MQ.QM1 is not set as the default queue manager, runmqsc is returning back stating, hey, WebSphere MQ queue manager not available.

To further dig into this, verified logs at -
i./var/mqm/errors/AMQERR01.LOG
ii. /var/mqm/qmgrs/MQ!QM1/errors/AMQERR01.LOG
In the above i. being the mq error log and ii. being the queue manager error log.

There is this MQ configuration file called mqs.ini, default location is /var/mqm
My mqs.ini is like this -
-----------------------------
AllQueueManagers:
#********************************************************************#
#* The path to the qmgrs directory, below which queue manager data *#
#* is stored *#
#********************************************************************#

QueueManager:

Prefix=/var/mqm
Directory=MQ!QM1
-----------------------------

In the content, there is no listing of default queue manager....
looked in IBM MQ InfoCenter and a sample file looked like this -
-----------------------------
AllQueueManagers:
#***********************************************************************#
#* The path to the qmgrs directory, below which queue manager data *#

Prefix=/var/mqm
Directory=saturn!queue!manager

QueueManager:
Name=pluto.queue.manager

Directory=pluto!queue!manager

DefaultQueueManager:
Name=saturn.queue.manager

ApiExitTemplate:

Module=/usr/ABC/auditor
Data=123

ApiExitCommon:
Name=MQPoliceman
Sequence=1
Function=EntryPoint
Module=/usr/MQPolice/tmqp
Data=CheckEverything
-----------------------------

So let me edit my file with appropriate default queue settings -
Just added these two lines at the end of the file -
DefaultQueueManager:
Name=MQ.QM1

Now the changes comes into action only after restarting the queue manager.
How to restart the queue manager?
Search in MQ info center - says, ps -ef | grep QNAME lists all the available processes, pick the queue manager process and kill -9.
Wow...
Let me see what I got here -
[mqm@localhost mqm]$ ps -ef | grep mqm | grep -i qm1
mqm 6418 1 0 12:22 ? 00:00:00 amqzxma0 -m MQ.QM1

mqm 6452 6436 0 12:22 ? 00:00:00 /opt/mqm/bin/amqpcsea MQ.QM1
mqm 13218 7791 0 13:34 pts/1 00:00:00 grep -i qm1

pid 6418 is the parent pid for all these process.
kill -9 6418 :)

Yeah,
[mqm@localhost mqm]$ ps -ef | grep mqm | grep -i qm1
mqm 13397 7791 0 13:39 pts/1 00:00:00 grep -i qm1

So, good to go now, start queue manager now

[mqm@localhost mqm]$ strmqm
There are 90 days left in the trial period for this copy of WebSphere MQ.
WebSphere MQ queue manager 'MQ.QM1' starting.
17 log records accessed on queue manager 'MQ.QM1' during the log replay phase.
Log replay for queue manager 'MQ.QM1' complete.
Transaction manager state recovered for queue manager 'MQ.QM1'.
WebSphere MQ queue manager 'MQ.QM1' started.

I have not mentioned the FQQMN (Fully Qualified Queue Manager Name), it picked the MQ.QM1 as default and start the manager.
Now, lets check runmqsc

major minor version errors

2010-05-26T23:36:00.002+05:30

These types of errors are caused by a Java version mismatch between the compiled proxies and your runtime.

"bad class file. class file has wrong version 50.0, should be 48.0."

Unsupported major.minor version 50.0
JSPG0091E: An error occurred at line: 2 in the file: /login.jsp
JSPG0093E: Generated servlet error from file: /login.jsp

Below are a list of some of the version numbers and their corresponding Java runtimes:
Version 50.0 = Java 1.6.x
Version 49.0 = Java 1.5.x
Version 48.0 = Java 1.4.x

The server is expecting 48.0 version of the code, meaning, code built with 1.4.x version of jvm, but, the supplied code was built against version 50.0 meaning 1.6.x version of the jvm.

What one can do to solve this is, if you use RAD kind of tools to build the code, configure build path to have appropriate JRE, clean your builds and re build.

uptime

2010-05-26T23:30:00.003+05:30

uptime is a measure of the time a machine has up been.
This is pretty useful command.

To know since when the system is up one can do like this at the terminal prompt
$uptime
11:10:27 up 9 mins, 2 users, Load average: 0.02, 0.24, 0.18

Determining system uptime in windows -

C:\> systeminfo | find "Time:"
System Up Time:            0 Days, 8 Hours, 7 Minutes, 19 Seconds

Note: Windows Vista Business 64-bit and Windows 7 do not return a "System Up Time" but "System Boot Time" instead.

C:\> net statistics server | find "since"
Server Statistics for \\COMPUTERNAME
 
Statistics since 8/31/2009 8:52:29 PM

remove directory

2010-04-22T22:30:00.001+05:30

If you need to remove a directory, or files and or folders under a directory, in say, Solaris you do like this,
say to remove cache under wstemp
rm -r wstemp/*
which removes files folders under wstemp recursively.
rm test.txt
deletes test.txt file
rm -i wstemp/*
inquires and prompts yes or no for each file
In Linux
rm -f - force removes a file
rm -fr - force removes directory

In DOS -
rmdir is the command to remove a directory.
rmdir dSample
removes if dSample dir is empty.
To force remove
rmdir /S dSample
removes dSample directory but inquires
rmdir /S /Q dSample
removes dSample directory and its sub directories quietly.

Enjoy your day.

Administrative console throws error 500 with java.lang.NullPointerExcetion

2010-04-12T23:29:00.002+05:30

Last Sunday, one of my friend got this problem.

Admin Console, when accessed, throws error 500 with java.lang.NullPointerExcetion.
SystemOut.log has the following entries

5ea42ee7 WebGroup I SRVE0180I: [adminconsole] [/admin] [Servlet.LOG]: /secure/logon.jsp: init
5ea42ee7 WebGroup I SRVE0180I: [adminconsole] [/admin] [Servlet.LOG]: /secure/layouts/browser_detection.jsp: init

5ea02ee7 WebGroup E SRVE0026E: [Servlet Error]-[]: java.lang.NullPointerException
at org.apache.jsp._console._jspService(_console.java:172)

I found this technote http://www-01.ibm.com/support/docview.wss?rs=180&uid=swg21177893 regarding NullPointerException, which states -
Resolving the problem
To resolve this issue:

1. Clean up the disk space problem.
2. Delete the /wstemp//preferences.xml file.
3. Try to login to administrative console. This should build a new preferences.xml with the correct data and should allow the user to login to administrative console.

My friend followed these steps and resolved the problem.

Installation Issues

2010-03-10T08:51:00.005+05:30

Mr.X installed WAS like this on Win 08 server-

Started to launcher.
Selected WAS installer.
The installer had successfully passed OS verification.
Then selected Cell Topology. WAS 6.1 and above gives you an option to install a Cell. Meaning, installer installs Dmgr, installs an appserver, and federates that to dmgr.
Now, with all the needed inputs, the installer started to install binaries, installed successfully dmgr, appserver and even successfully federated everything.

Now, as this guy didnt configured security at the time of installation, wants to do it in the post installation.

He did like this -
After immediately installing, he ran the ivt (installation verification test).
Then went to admin console, kicked in security setup process.

WHAT IS HE MISSING?

The error what he got was - after configuring security, he wanted to bounce the services, bounce dmgr, bounce node agent, bounce server.
server was failing to start.
dmgr cannot recognize server.

What to do?ADMR0111E is one of the errors.

WASService command

2010-03-09T06:17:00.004+05:30

Today one of colleague was trying to add a jvm to Windows Service.
This is the syntax for the command -
WASService.exe -add service_name
-serverName server_name
-profilePath server_profile_directory
[-wasHome
app_server_root]
[-configRoot configuration_repository_directory]
[-startArgs additional_start_arguments]
[-stopArgs additional_stop_arguments]
[-userid user_id -password password]
[-logFile service_log_file]
[-logRoot server_log_directory]
[-restart true | false]
[-startType automatic | manual | disabled]

This guy is fighting with some set of parameters. He is executing, command runs, he goes to the services, he finds that specific jvm in the services, but when he starts it, it simply says *started*, upon right clicking on the service, he sees only start option, remaining faded out.

So, whats the problem?
Go through the command options properly -
http://publib.boulder.ibm.com/infocenter/wasinfo/v6r1/index.jsp?topic=/com.ibm.websphere.base.doc/info/aes/ae/rins_wasservice.html
He was trying to add jvm to win services like this -
WASService.exe add blabla -logFile path/to/a/location/server.log -logRoot path/to/a/location/

yata yata yata

The problem is - one should pass SERVER LOG FILE as logFile and SERVER_LOG_LOCATION not to another location.
The WASService command looks for a file named server_name .pid to determine if the server is running.

So, if you want to add a jvm, by name server1 to Win services, you need to pass server1 log location.

Have Fun

WebSphere Hypervisor Setup

2010-01-31T23:37:00.009+05:30

Well, Lets see what we need to for this.
WebSphere Hypervisor version 7. Follow this URL http://www-01.ibm.com/software/webservers/appserv/hypervisor/
You need to download the following

When searched in infocenter for hypervisor, it gave me very clear instructions. Here are those links
http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=/com.ibm.websphere.virtualimages.doc/info/ae/ae/welcome_virtual.html
http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0/index.jsp?topic=/com.ibm.websphere.virtualimages.doc/info/ae/ae/tins_virt_install_vmware_esx.html

So, you those files from IBM. Whatelse you need?

1. SLES 10, sp3.
Goto novell.com, get SuSE Linux Enterprise Edition.

2. VirtualBox -
http://www.virtualbox.org/
Download virtualbox, install it, create a suse virtual machine.

3. Get cygwin.
http://www.cygwin.com/

4. Before you begin, you need to mount these tgz files to cygwin.
When cygwin is installed it creates directories like this
Directory Structure

Cygwin attempts to duplicate the directory structure of a Linux System within the "c:\cygwin" folder:

To not waste time on mounting another directory into cygwin, simply copy those tgz files to c:\cygwin\tmp, which are avaliable thru cygwin shell.

5. Now, openup a cygwin shell.
You have downloaded tgz file. A tgz file is a gunzip file. To uncompress it, in general, one can use gunzip command.
gunzip filename.tgz
is an example.
Or, on linux platforms, tar gives a switch *z* to uncompress gz, tgz files
Now, at the cygwin prompt -
cd /tmp
tar xvzf filename.tgz
Use the above command and replace filename.tgz with all those four files.
This uncompresses tgz file to a tar file and tar file will be uncomplressed.
6. Above command creates files like
vmdk, vmx files.
7. For ease of use, I have created another directory say, c:\vmdk_files
and copied all these files into that directory. These are the files -

8. So, we have vmdk files, and virtual machine. By the way, what is a vmdk file? :)
vmdk = virtual machine disk.
When we create a virtual machine, it will create a hdd readable by it. virtualbox by default creates vdi file. vmdk is another kind of such virtual disk file. Now, we need to add that virtual disk to the virtual machine as a secondary disk.

9. This is how you do it -
Open ur virtualbox
point to the virtual machine

As pointed in the above, I have selected suse, under that, select *Storage*.
10.

As shown above, hit on that *Add Attachment*, it gives two options, add hard disk or cd/dvd/. Select, obviously, disk.
11.
So, we mounted these vmdsiks to our virtual machine. Lets start and see -
12. These 4 are the mounted disks -

tar

2010-01-30T03:26:00.002+05:30

was.7005.nd.linux.vmware.esx.sles.os.tgz is big file, 2.33GB. When uncompress, its 12GB.

$tar xvfz was.7005.nd.linux.vmware.esx.sles.os.tgz
SLES10SP2-32-flat.vmdk
tar: SLES10SP2-32-flat.vmdk: Wrote only 4607 of 10240 bytes
SLES10SP2-32.vmdk
tar: Exiting with failure status due to previous errors

What to do??

vmdk disks

2010-01-29T11:20:00.002+05:30

While I was going through Dileep Kumar's Blogpost WebSphere Hypervisor Edition and VirtualBox, Hypervisor version attracted me a lot. So, I wanted to tryout installation the Hypervisor version 7.0.0.5 on my VirtualBox.

I have lot to share on this and tomorrow I will publish that.

InfoCenter 6.1

2010-01-28T01:09:00.002+05:30

Today, InfoCenter URL is spitting with this message

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /infocenter/wasinfo/v6r1/advanced/searchView.jsp.

Reason: Error reading from remote server

IBM_HTTP_Server/6.0.2.13 Apache/2.0.47 (Unix) Server at publib.boulder.ibm.com Port 80

According to IBM Technote http://www-01.ibm.com/support/docview.wss?rs=177&context=SSEQTJ&dc=DB560&dc=DB520&uid=swg21316599&loc=en_US&cs=UTF-8&lang=en&rss=ct177websphere

Problem(Abstract)
A Proxy Error in IBM® HTTP Server (IHS) causes a 502 error response in the browser.

Symptom
The user sees a 502 Proxy Error in the browser that says:

The proxy server received an invalid response from an upstream server. The proxy server could not handle the request ....

The IBM HTTP Server error log displays errors similar to:

proxy: Error reading from remote server returned by ....

Cause
The most common cause of this problem is when the back-end web server is either not using KeepAlive, or is using too low of a value for KeepAlive.

Environment
IBM HTTP Server is configured as a proxy or reverseproxy in front of some other back-end web server.

Resolving the problem
There are two possible solutions to this problem:

1) Disable KeepAlive in IBM HTTP Server, by adding these directives into your IBM HTTP Server config (httpd.conf):

SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1

OR

2) Increase the KeepAlive value in the back-end web server. The KeepAlive value for the back-end web server should be at least double or triple whatever IBM HTTP Server is using for KeepAlive. The default KeepAlive for IBM HTTP Server is 15 seconds. So the back-end web server should be configured to use KeepAlive of 30 or 45 seconds.
-------------------------------------

Here the question is, who is going set those values on the IBM remote servers? :):)

Migration Notes #2

2010-01-27T00:52:00.002+05:30

The migration tools are used as part of a four-step migration process:
1. Run WASPreUpgrade on the existing WebSphere Application Server configuration.
2. Uninstall the existing version of WebSphere Application Server.
3. Install the new version of WebSphere Application Server.
4. Run WASPostUpgrade on the new version.
In the second step, it is recommended that rather than uninstalling the existing version, it be made dormant. By keeping the existing software installed on the machine, it will be much easier to back out of the migration should unexpected problems arise.

The fully automated migration includes the following steps:
1. Migrate the existing Version 5.x deployment manager to Version 6.0 using the migration
tools.
2. Migrate the HTTP servers and HTTP server plug-ins on all Web tier nodes.
3. Individually migrate the application server nodes using the migration tools.

The WASPreUpgrade and WASPostUpgrade tools effectively move the existing configuration into WebSphere Application Server Version 6.0.

Ideal WAS Environment

Migration Notes #1

2010-01-26T22:55:00.003+05:30

Why to migrate?
Two important things to my understanding.
For new features.
For maintenance support.
-> New Features
Again two views. Developer view and support view.
ex., My developer called me one day, said, struts framework x.xx version is throwing error on the development. I paid a look into the log and search for the errors in the IBM. Found that, that version of JVM donot support this version of struts. So, what to do? Its the developers call to have the latest copy the JVM which can support this version of struts and apps.
This is what is developer initiated migration.
Admin initiated migration -
Admin may initiate the migration too. Some of the app server errors must have been addressed in the new version of the application server and so the need for migration.
-> Support
If the product is end of the support, there is a need to migrate to supported version.

While migrating, one should need to understand inconsistencies and deprecations between the target and source environments.
In considering the incompatibilities and deprecations, we look at these major areas:
* J2EE differences
* J2SE/JDK differences
* Application Server runtime differences
* Programming Model Extension differences
* Third Party Library differences

-> J2EE Differences
Java Code, as we all know, is forward compatible. Meaning that, code compiled in JDK 1.3.0 runs on 1.4.0, but, may throw some deprecation warnings.
Its a good practice for the developers to address those deprecations in the code. So, when one plans to migrate from x version to y version, the development team should plan to revisit their code.

What you want to know about HTTP session persistence

2009-12-14T23:45:00.004+05:30

Comment lines: Erik Burckart: What you want to know about HTTP session persistence -

Just the FAQs

In general, I get a lot of questions from various customers about HTTP session persistence. With Web 2.0 technologies taking off, more and more Web applications are being redesigned, and as they get changed, these same questions come up even more frequently. If you are involved in redesigning any Web applications for Web 2.0, here are answers to some of the questions you might soon be asking.

1. If I don’t need session persistence, can I turn it off?

Yes, you can configure session management to run with in-memory sessions, which is actually the default. You can still use HttpSessions in this mode, but if a failure occurs, the data stored in the HttpSessions will be lost.

selinux blocks jvm

2009-12-12T02:37:00.002+05:30

SELinux is preventing java from loading /software/inst/JDK/jre.pak/repository/package.java.jre/java/jre/bin/libj9thr23.so which requires text relocation.
Detailed DescriptionThe java application attempted to load /software/inst/JDK/jre.pak/repository/package.java.jre/java/jre/bin/libj9thr23.so which requires text relocation. This is a potential security problem. Most libraries do not need this permission. Libraries are sometimes coded incorrectly and request this permission. The SELinux Memory Protection Tests web page explains how to remove this requirement. You can configure SELinux temporarily to allow /software/inst/JDK/jre.pak/repository/package.java.jre/java/jre/bin/libj9thr23.so to use relocation as a workaround, until the library is fixed. Please file a bug report against this package.
Allowing Access
If you trust /software/inst/JDK/jre.pak/repository/package.java.jre/java/jre/bin/libj9thr23.so to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/software/inst/JDK/jre.pak/repository/package.java.jre/java/jre/bin/libj9thr23.so'" You must also change the default file context files on the system in order to preserve them even on a full relabel. "semanage fcontext -a -t textrel_shlib_t '/software/inst/JDK/jre.pak/repository/package.java.jre/java/jre/bin/libj9thr23.so'"

The Phurnace Deliver Configuration Viewer for WebSphere

The Phurnace Deliver Configuration Viewer provides WebSphere customers with a graphical presentation of applications, configurations, servers, clusters, nodes, and domains of an application server environment. The view can be customized by scope, application, or individual component. Interrelations between the components are shown as connected lines, so at a glance, customers can determine if a configuration is associated with a particular server, cluster, or application.

hostname issues

2009-11-28T00:01:00.002+05:30

I am still fighting with Portal Express installation. Now, I have changed my strategy and trying to install as silent with responsefile.

-silent
-G licenseAccepted="true"
-W setupTypePanel.selectedSetupTypeId="full"
-W globalInstall.location="/opt/IBM/WebSphere"
-W wasPanel.installChoice="install"

#
# Description: Sometimes the Portal install program cannot detect an existing

#
# When this error occurs, and you are certain that there is a valid WAS at the

#
################################################################################

# -W was.undetectedWas="/opt/IBM/WebSphere/AppServer"

and so on.
Now, as the responsefile expected, I have installed AppServer. I just wanted run and check, so called startServer.sh server1, to my surprise, it failed.
Stacktrace -
SystemErr R com.ibm.ws.exception.ConfigurationError:javax.naming.ConfigurationException: Cannot get canonical host name for server.

serverindex.xnl has hostname="null".
This is because -
Portal Server expected localhost.localdomain.com as hostname to localhost.localdomain.

I reverted /etc/hosts back to localhost.localdomain
and I have typed in hostname="localhost" in serverindex.xml.
Server started successfully.

Now, to kick start the PortalExpress, I am a kinda stuck, because, portal expects hostname as localhost.localdomain.com.
Portal cannot work with hostname as "localhost.localdomain.com", AppServer cannot run with host name *localhost.localdomain.com*. What a DEADLOCK!!!!!

build failed again

2009-11-26T19:18:00.003+05:30

Well!! n-th run, build failed again with same message as posted here - http://javagongura.blogspot.com/2009/11/build-failed-on-line-3121.html

After this step. installation aborts.
Checked the App Server installation log, it was a successful installation.
Though its a failed installation, I tried to start the app server services.
I found some *amazing* things in startServer.log -

This line in the above stack trace *Executable: [/opt/XYZWEBSPHEREXYZ/AppServer/java/bin/java] does not appear to be a valid executable. Process could not be created.* amazed me.
Why startServer is trying to look for java in /opt/XYZWEBSPHEREXYZ/AppServer/java/bin/java?

So, I have created folder structure like /opt/XYZWEBSPHEREXYZ/AppServer/java/bin/ and created a softlink to original appserver/java/bin/java.
But, its looking for remaining binaries in the same location.
So, need to create softlink for the entiar installation under /opt/XYZWEBSPHEREXYZ/AppServer/

Lets see...
BTW - Found a technote on this -
http://www-01.ibm.com/support/docview.wss?uid=swg21202564
The technote mentions that, because its a broken installation, you get such an error.

EJPIC0067E

2009-11-20T20:48:00.002+05:30

I am installing PortalExpress v 6.1.0.0 on RHEL 5.2 on my laptop.

Some tips -
Run install.sh -console

You may encounter EJPIC0067E error.
EJPIC0067E: {0} requires a fully-qualified host name that is recognized by the DNS server. Short host names, loopback addresses, IP addresses and illegal characters such as blanks are not allowed. Enter the host name again.
Explanation: This installation requires a fully-qualified host name. Short host names, loopback addresses, and IP addresses are not allowed.
User Response: Enter the host name again.

To resolve this -
Just check the complete name of your box
uname -a
for me it is
localhost.localdomain
Now -
vi /etc/hosts as root
edit localhost.localdomain to localhost.localdomain.com

Profile Creation, New in 6.1

2009-10-30T23:19:00.003+05:30

In 6.0 - To create a profile one can call AppServerPath/bin/ProfileCreator/pctSolaris.bin command or wasprofile.sh command.

Ex.,
./wasprofile.sh -create -profileName bladetcb6profile -profilePath /usr/IBM/WebSphere/AppServer/profiles/bladetcb6profile -templatePath /usr/WebSphere/AppServer -profileTemplates/default -nodeName bladetcb6node -cellName bladetcb6Cell -hostName bladetcb6.rtp.raleigh.ibm.com

Or you can kick this process thru firststeps.

In 6.1, wasprofile.sh command is available too but it is depricated. Instead you have manageprofil.sh command.
ex.,
manageprofiles.sh -create
-profileName shasti
-profilePath /shasti/WebSphere
-templatePath /opt/IBM/WebSphere/AppServer/profileTemplates/dmgr
-cellName cell1
-hostName planetaix
-nodeName dmgr1

The reason for this is, since you already installed 6.0.xx, you have already used default ports. Now, for the new installation, you need to tell the installer not to look for default ports.

Collector Tool

2009-07-23T20:04:00.002+05:30

Someone asked me how to run collector tool. IBM Doc says, run the tool not from APPSERVER_INST_PATH/bin, but run from working directory. What exactly is that?

The collector tool gathers information about your WebSphere Application Server installation and packages it in a Java archive (JAR) file that you can send to IBM Customer Support to assist in determining and analyzing your problem. Information in the JAR file includes logs, property files, configuration files, operating system and Java data, and the presence and level of each software prerequisite.

collector command - summary option

WebSphere Application Server products include an enhancement to the collector tool beginning with Version 5.0.2, known as the collector summary option.

The collector summary option helps you communicate with WebSphere Application Server technical staff at IBM Support. Run the collector tool with the -Summary option to produce a lightweight text file and console version of some of the information in the Java archive (JAR) file that the tool produces without the -Summary parameter. You can use the collector summary option to retrieve basic configuration and prerequisite software level information when starting a conversation with IBM Support.

The collector summary option produces version information for the WebSphere Application Server product and the operating system as well as other information. It stores the information in the Collector_Summary.txt file and writes it to the console. You can use the information to answer initial questions from IBM Support or you can send the Collector_Summary.txt file directly to IBM Support.

Collector tool collect key information including ffdc, configuration, logs, and so on and makes a jar file with all the information. So, depending on your configuration and all, jar file may occupy lot of space. So, IBM docs says that, create a folder out of appserver installation path.
Example,
mkdir /tmp/collector
cd /tmp/collector

Then run the script as needed
/appserver/instpath/profiles/profilename/bin/collector.sh
or
/appserver/instpath/profiles/profilename/bin/collector.sh -summery

Symbolic links

2009-07-23T19:30:00.006+05:30

Sometimes, in the process of WebSphere, IHS Administration, it may require you to create symbolic links. This is the procedure.

ln is the command to create symbolic links.
$man ln
User Commands ln

NAME
ln - make hard or symbolic links to files

SYNOPSIS
/usr/bin/ln [-fns] source_file [target]

/usr/bin/ln [-fns] source_file... target

/usr/xpg4/bin/ln [-fs] source_file [target]

/usr/xpg4/bin/ln [-fs] source_file... target

DESCRIPTION
In the first synopsis form, the ln utility creates a new
directory entry (link) for the file specified by
source_file, at the destination path specified by target. If
target is not specified, the link is made in the current
directory. This first synopsis form is assumed when the
final operand does not name an existing directory; if more
than two operands are specified and the final is not an
existing directory, an error will result.

In the second synopsis form, the ln utility creates a new
directory entry for each file specified by a source_file
operand, at a destination path in the existing directory
named by target.
..............................

Example -
Developers wanted to have a look at SystemOut.log and SystemErr.log. They dont have uid on the box. So, I need to create a web link to this through HTTP Server.
I did like this.
I have created a document root called logs.
/logs
I created symbolic links to SystemOut.log and SystemErr.log like this
ln -s source destination
This creates a softlink *from* a file to a *file*
$ln -s /path/to/appserver/profiles/profilename/logs/servername/SystemOut.log SystemOut.log
$ln -s /path/to/appserver/profiles/profilename/logs/servername/SystemErr.log SystemErr.log
This created me two files SystemOut.log and SystemErr.log under /logs
if I ls -ltr on /logs, I get this list
SystemOut.log -> /path/to/appserver/profiles/profilename/logs/servername/SystemOut.log
SystemErr.log -> /path/to/appserver/profiles/profilename/logs/servername/SystemErr.log

Now, I have created a html file, say, index.html with hyperlinks like this -
Server Logs
< A HREF="SystemOut.log">SystemOut< / A>< br />
< A HREF="SystemErr.log">SystemErr< / A>

Enable Trace in Plugin-cfg.xml

2009-07-14T21:05:00.004+05:30

WebServer Plugin writes a log, by default its named as http-plugin.log, by default placed under PLUGIN_HOME/logs/
Plugin writes Error messages into this log. The attribute which deals with this is
< Log > in the plugin-cfg.xml
Ex.,
< Log LogLevel="Error" Name="/usr/IBM/WebSphere/Plugins/logs/http_plugin.log" / >

According to above line all Error messages will be written into http-plugin.log.

How to enable trace in the plugin-cfg.xml? if that is the question, do like this -

< Log LogLevel="Trace" Name="/usr/IBM/WebSphere/Plugins/logs/http_plugin.log" / >

From the InfoCenter -
Plug-in Problem Determination Steps
The plug-in provides very readable tracing which can be beneficial in helping to figure out the problem. By setting the LogLevel attribute in the config/plugin-cfg.xml file to Trace, you can follow the request processing to see what is going wrong.
Note: If you are using a Veritas File System with large file support enabled, file sizes up to two terabytes are allowed. In this case, if you set the LogLevel attribute in the plugin-cfg.xml file to LogLevel=Trace, then the http_plugin.log file might grow quickly and consume all available space on your file system. Therefore, you should set the value of the LogLevel attribute to ERROR or DEBUG to prevent high CPU utilization.
At a high level, complete these steps.
The plug-in gets a request.
The plug-in checks the routes defined in the plugin-cfg.xml file.
It finds the server group.
It finds the server.
It picks the transport protocol, HTTP or HTTPS.
It sends the request.
It reads the response.
It writes it back to the client.

Multiple Authentication Bypass Vulnerabilities within IBM WebSphere Application Server

OVERVIEW:
Two vulnerabilities in IBM WebSphere Application Server have recently been made public. IBM WebSphere Application Server is a software application server that uses web technologies and can be implemented on many common operating systems. Both vulnerabilities may allow malicious users to bypass authentication required to access a service running on the vulnerable server. Successful exploitation may allow attackers to gain unauthorized access to the service, which may lead to other attacks.

DESCRIPTION:
IBM has confirmed the existence of two vulnerabilities that may allow a remote attacker to bypass application server authentication. Exploiting these vulnerabilities could allow an attacker to access restricted services, which may then lead to other attacks. Both vulnerabilities are associated with WS-Security, which is the security implementation within the Java API for XML Web Services (JAX-WS).
The first vulnerability discovered within WS-Security, referenced and addressed by IBM in PK72138, can only be exploited when the security policy is implemented at the 'Operational Level'. When this policy is established, WS-Security does not properly handle inbound requests that lack a SOAPAction or WS-Addressing Action. An attacker can craft a malicious inbound request to exploit this vulnerability. Successful exploitation may allow attackers to bypass certain security restrictions, which may then lead to other attacks.
The second vulnerability, referenced and addressed by IBM in PK75992, arises in the way WS-Security validates the 'UsernameToken' object. It is possible for WS-Security to incorrectly validate these tokens, allowing a malicious user to bypass the authentication process. This may allow a malicious user to conduct further attacks.

RECOMMENDATIONS:
We recommend the following actions be taken:
* Apply appropriate patches provided by IBM to vulnerable systems immediately after appropriate testing.
* Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Applet Security -

2009-06-29T19:02:00.004+05:30

When an app is accessed through https, if there is no trust between app server and browser jre, client jvm may spit SSL HandShake Error. Error may go like this -
Error Occured during session initialization: Error SSL connecting to server:9446:javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Its very simple to solve this. One needs to import client certificate into jre/lib/security/cacerts which is the trust store of the JVM.
example -
"C:\Program Files\Java\jre1.5.0_11\bin\keytool" -import -trustcacerts -keystore "C:\Program Files\Java\jre1.5.0_11\lib\security\cacerts" -storepass changeit -noprompt -alias ALIAS_NAME -file "\CERTIFICATE_NAME"

While using df

2009-06-17T20:45:00.003+05:30

Solaris
df -h is the command to display available disk free space in bytes
e.g.,
$df -h
Filesystem size used avail capacity Mounted on
/dev/md/dsk/d84 3.9G 136M 3.8G 4% /var
swap 6.6G 992K 6.6G 1% /tmp
/dev/md/dsk/d101 20G 7.8G 12G 41% /software

Equivalent df in AIX
df -g

AIX df command

2009-06-17T20:35:00.000+05:30

df Command

Purpose

Reports information about space on file systems. This document describes the AIX df command as well as the System V version of df.

Syntax

df [ [ -P ] | [ -I | -M | -i | -t | -v ] ] [ -k ] [ -m ] [ -g ] [ -s ] [FileSystem ... | File... ]

Description

The df command displays information about total space and available space on a file system. The FileSystem parameter specifies the name of the device on which the file system resides, the directory on which the file system is mounted, or the relative path name of a file system. The File parameter specifies a file or a directory that is not a mount point. If the File parameter is specified, the df command displays information for the file system on which the file or directory resides. If you do not specify the FileSystem or File parameter, the df command displays information for all currently mounted file systems. File system statistics are displayed in units of 512-byte blocks by default.

The df command gets file system space statistics from the statfs system call. However, specifying the -s flag gets the statistics from the virtual file system (VFS) specific file system helper. If you do not specify arguments with the -s flag and the helper fails to get the statistics, the statfs system call statistics are used. Under certain exceptional conditions, such as when a file system is being modified while the df command is running, the statistics displayed by the df command might not be accurate.

Note:

Some remote file systems, such as the Network File System (NFS), do not provide all the information that the df command needs. The df command prints blanks for statistics that the server does not provide.

The df command does not fully support NFSv4 filesystems. Use the nfs4cl command to extract block and space information.

Flags

-g	Displays statistics in units of GB blocks. The output values for the file system statistics would be in floating point numbers as value of each unit in bytes is significantly high.
-i	Displays the number of used inodes and the percentage of inodes in use for the file system. This output is the default when the specified file system is mounted.
-I	Displays information on the total number of blocks, the used space, the free space, the percentage of used space, and the mount point for the file system.
-k	Displays statistics in units of 1024-byte blocks.
-m	Displays statistics in units of MB blocks. The output values for the file system statistics would be in floating point numbers as value of each unit in bytes is significantly high.
-M	Displays the mount point information for the file system in the second column.
-P	Displays information on the file system in POSIX portable format. When the -P flag is specified, the header line appears similar to: Filesystem 512-blocks Used Available Capacity Mounted on\n If the -k, -m or -g flag is specified in addition to the -P flag, the column heading 512-blocks is replaced by the respective units, depending on which of these flags is used with the -P flag. File system statistics are displayed on one line in the following order: FileSystem, TotalSpace, UsedSpace, FreeSpace, UsedPercentage, MountPoint
-s	Displays statistics on unmounted JFS or Enhanced JFS file systems by the command line arguments. If there are no arguments specified, the -s flag has no effect. If the file systems specified by the argument are currently mounted or an argument is a file, the -s flag has no effect for that particular argument. To collect statistics on unmounted file systems, an argument must be a JFS or Enhanced JFS file system mount point or device, the file system must be listed in /etc/filesystems, and the user must have read access to the device.
-t	Includes figures for total allocated space in the output.
-v	Displays all information for the specified file system.

The values of the output parameters with the flags -m and -g would be rounded off to nearest second decimal digit. If all or any two of the -k, -m and -g flags are specified, the last one specified takes effect.

Exit Status

This command returns the following exit values:

0	Successful completion.
>0	An error occurred.

Examples

To display information about all mounted file systems, enter:

df

If your system has the /, /usr, /site, and /usr/venus file systems mounted, the output from the df command resembles the following:

Filesystem 512-blocks Free   %Used   Iused  %Iused  Mounted on
/dev/hd0    19368     9976    48%     4714    5%     /
/dev/hd1    24212     4808    80%     5031   19%     /usr
/dev/hd2     9744     9352     4%     1900    4%     /site
/dev/hd3     3868     3856     0%      986    0%     /usr/venus

To display information about /test file system in 1024-byte blocks, enter:

df -k /test

Filesystem    1024 blocks    Free    %Used   Iused  %Iused  Mounted on
/dev/lv11         16384     15824       4%      18      1%  /tmp/ravi1

This displays the file system statistics in 1024-byte disk blocks.

To display information about /test file system in MB blocks, enter:
```
df -m /test
```
```
Filesystem    MB blocks    Free    %Used    Iused  %Iused  Mounted on
/dev/lv11       16.00     15.46       4%       18      1%  /tmp/ravi1
```
This displays file system statistics in MB disk blocks rounded off to nearest 2nd decimal digit.
To display information about the /test file system in GB blocks, enter:
```
df -g /test
```
```
Filesystem    GB blocks   Free     %Used    Iused  %Iused  Mounted on
/dev/lv11          0.02   0.02        0%       18      1%  /tmp/ravi1
```
This displays file system statistics in GB disk blocks rounded off to nearest 2nd decimal digit.
To display available space on the file system in which your current directory resides, enter:
```
cd/
df .
```
The output from this command resembles the following:
```
Device   512-blocks  free   %used   iused   %iused  Mounted on
/dev/hd4    19368    9976    48%     4714    5%     / 
```

Files

/etc/filesystems	Lists the known file systems and defines their characteristics.
/etc/vfs	Contains descriptions of virtual file system types.

Solaris df, du, ls commands

2009-06-17T20:11:00.004+05:30

Solaris df command

New df, du, and ls Options

The df, du, and ls commands have a new h option for displaying disk usage and file or file system sizes that are easy to understand.

The default form of the df command displays file system size in blocks (512 bytes). The df output, in kilobytes, follows:

$ df -k / /usr
Filesystem kbytes used avail capacity Mounted on
/dev/dsk/c0t0d0s0 192056 94788 78063 55% /
/dev/dsk/c0t0d0s6 1982988 829966 1093533 44% /usr

The same file system sizes displayed in powers of 1024 follows:

$ df -h / /usr
Filesystem size used avail capacity Mounted on
/dev/dsk/c0t0d0s0 188M 93M 76M 55% /
/dev/dsk/c0t0d0s6 1.9G 811M 1.0G 44% /usr

The default form of the du command displays disk space in blocks (512 bytes). The du output, in blocks, follows:

% du -s k*
100 kadmin
98 kadmin.local
98 kdb5_util
90 keyserv
10 killall

The same disk space displayed in powers of 1024 follows:

% du -h k*
50K kadmin
49K kadmin.local
49K kdb5_util
45K keyserv
5K killall

The default form of the ls -l command displays file size in bytes. Use the ls -lh command to display file size in powers of 1024:

% ls -lh k
-r-xr-xr-x 1 root bin 49K Nov 30 03:32 kadmin
-r-xr-xr-x 1 root bin 49K Nov 30 03:32 kadmin.local
-r-xr-xr-x 1 root bin 49K Nov 30 03:32 kdb5_util
-r-xr-xr-x 1 root sys 44K Nov 25 04:37 keyserv
-r-xr-xr-x 1 root bin 4.3K Nov 25 04:36 killall

Remember, some commands needs you to be root. So, you switch to su to root.
Two important things here -
1. from ur profile, if u say
$su root
takes you to root with current shell. Means that, though u r root, u still carry ur .profile and ur env variables.
2. if u want to have root's env variables -
su - root or
su root
after getting into root

uninstall fixpacks

2009-03-27T19:27:00.003+05:30

Someone asked me how to troubleshoot fixpack uninstallation process.

Befroe going into that, read the following from UpdateInstaller README. You can find this under Update_Inst_Path/docs/raedme_updateinstaller.txt/pdf/html

3.0 Uninstalling maintenance packages

This topic describes how to use the Update Installer for WebSphere
Software to uninstall interim fixes, fix packs, and refresh packs. The
Update Installer for WebSphere Software is also known as the update
installer program, the updateInstaller program, and the Update
installation wizard.

Use the proper authorizations to successfully uninstall product updates.
Use the update installer program as the root user on a Linux or UNIX
platform, or as the administrator on a Windows platform.

The Update Installer wizard is an InstallShield for Multiplatforms
wizard that runs with either a graphical user interface or in silent
mode with a response file.

Important: See 4.3, "Known problems and workarounds for the update
command" for information about known problems and workarounds.

The following descriptions contain reference information about
uninstalling interim fixes, fix packs, and refresh packs on WebSphere
Application Server products:

Overview of the uninstall procedure
To uninstall a maintenance package:
1. Use the update installer to install the maintenance package,
which creates a backup file in the
app_server_root/properties/version/nif/backup directory. IBM
does not support user modifications to backup files.
2. Use the update installer program to remove the maintenance
package as described in this topic.

Viewing the fix level of the node
You can use the 5.0, "versionInfo command" in the
app_server_root/bin directory to display the exact fix and
version level of the product. However, do not use the
versionInfo command while installing or uninstalling a
maintenance package.

Do not launch multiple copies of the Update Installer wizard at one
time: Concurrent launches of the update installer program are not
supported. Performing more than one update at the same time can produce
unpredictable results, which might include a failed or faulty
installation.

Required information

The graphical interface requires the following information that you
must supply:

Table 4. Information required when uninstalling a maintenance package

+-----------------------+----------------------+----------------------+

The following procedure describes how to uninstall a maintenance
package.

1. Log on to the operating system.

[Linux] In addition, verify that the umask setting is 022. To verify
the umask setting, issue the following command:

umask

To set the umask setting to 022, issue the following command:

umask 022

2. Change directories to the updi_root directory.
3. [Windows] Use the Windows Services panel to stop all services for
WebSphere Application Server processes.
4. Stop all Java processes that use the IBM Software Developer Kit (SDK)
that the WebSphere Application Server product provides.

Before uninstalling interim fixes, fix packs, and refresh packs on a
machine, stop all Java processes on the machine that use the IBM SDK,
Java Technology Edition that WebSphere Application Server provides.

WebSphere Application Server processes include:
* Application server processes
* The nodeagent process on an application server node when the node
is federated into a deployment manager cell
* The dmgr process for the deployment manager server

Stop all Java processes if necessary. If you uninstall a maintenance
package while a WebSphere Application Server-related Java process
runs, IBM does not guarantee that the product can continue to run
successfully, or without error.

5. Use the update installer to uninstall the maintenance package.

Uninstall the interim fix on each application server node in a cell
before uninstalling the maintenance package from the deployment
manager node.

Issue one of the following commands to uninstall with the graphical
interface:

+--------------------------------+-------------+----------------------+

This procedure results in uninstalling maintenance packages to update
WebSphere software.

After uninstalling maintenance packages, you can continue to use the
WebSphere software.

Rolling back changes to existing profiles: Some maintenance packages
for WebSphere Application Server products, such as Refresh Pack 2,
update existing profiles. If you roll back a maintenance package that
contains a profile update, also use any undo scripts provided with the
profile update script to roll back changes to the existing profiles.

The readme file for a maintenance package describes scripts that update
and scripts that roll back profile fix levels. For example, Refresh Pack
2 for WebSphere Application Server includes required service for the
JDBC resource provider templates in existing profiles. See the readme
for the profile update and undo scripts for the JDBC-related update for
more information.

Deleting profiles created by a service level that is now rolled back:
See Profiles remain at the Version 6.0.2 level after roll back for a
description of a limitation that requires profiles to be at the same
service level or at a lower service level that the WebSphere Application
Server product.

For example, suppose that you install Fix Pack 1 for Version 6.1
(Version 6.1.0.1), create a new profile, and then roll back Fix Pack 1.
You must delete the profile that you created at the Version 6.1.0.1
level to avoid possible problems.

3.1 uninstall.txt

The Update Installer for WebSphere Software can use an options response
file to uninstall maintenance packages from a command line interface.

The uninstall.txt file has one directive that identifies the backup file
for uninstalling a service update. Comments in the file describe how to
set the string value.

The Update Installer for WebSphere Software wizard reads the options
file to determine uninstall choices. The Update Installer uninstalls the
maintenance package in silent mode, instead of displaying a graphical
user interface.

3.1.1 Location of the response file

The sample options response file is named uninstall.txt. The file is in
the updi_root/responsefiles directory after you unzip the Update
Installer for WebSphere Software into the installation root directory of
the WebSphere software product.

3.1.2 Uninstalling silently

The options file supplies the values to the Update installer wizard when
uninstalling silently. The wizard reads the options file to determine
responses and does not display the graphical user interface.

The following command uses a copy of the options file named
myresponsefile.txt to provide uninstall option responses during a silent
uninstall:

./update.sh -options "responsefiles/myresponsefile.txt" -silent

If you do not use the -silent option, the wizard uses the response file
to provide initial values for the graphical interface:

./update.sh -options "responsefiles/myresponsefile.txt"

3.1.3 Response file user entry validation

In a silent uninstall, response file validation has been coded into the
uninstall process. If the validation does not pass, the failure is
recorded in the log files in the app_server_root/logs/update/tmp
directory.

Location of the maintenance package to be uninstalled

Default directive setting
-W backup.package=""

Valid setting
You must set this directive to the location of the
backup file. The backup file reverses the application
of the maintenance. For example, you might specify the
following location on a Linux system:
/opt/properties/version/nif/backup/maintenance_package_to_uninstall

Error identifiers:

* The maintenance package cannot be uninstalled.
Uninstalling the maintenance would break the
following superseding maintenance packages.
Uninstall the superseding maintenance packages
first: list_of_superseding_maintenance_packages
* This maintenance package cannot be uninstalled. The
following maintenance packages are dependent on the
package that you are attempting to uninstall:
list_of_dependent_maintenance_packages
* This maintenance package cannot be uninstalled. The
following maintenance packages are dependent on the
APARs you are attempting to uninstall:
list_of_dependent_maintenance_packages
* No installation backup packages are available for
uninstalling maintenance.

Product location

Although uninstalling maintenance from another product is
possible, always use the Update installer wizard from the
directory structure of the product that you are updating if
possible. Problems can occur when a mismatch between product
SDKs occurs, for example.

Do not use this directive unless absolutely necessary.

Default directive setting
-W
product.location="SPECIFY_PRODUCT_INSTALL_LOCATION_HERE"

Valid setting
You must set this directive to the installation root
directory of the alternate product. For example, you
might specify the following location on a Linux
system:
/opt/IBM/WebSphere/AppServer2

Error identifiers:

* The maintenance package cannot be uninstalled.
Uninstalling the maintenance would break the
following superseding maintenance packages.
Uninstall the superseding maintenance packages
first: list_of_superseding_maintenance_packages
* This maintenance package cannot be uninstalled. The
following maintenance packages are dependent on the
package that you are attempting to uninstall:
list_of_dependent_maintenance_packages
* This maintenance package cannot be uninstalled. The
following maintenance packages are dependent on the
APARs you are attempting to uninstall:
list_of_dependent_maintenance_packages
* No installation backup packages are available for
uninstalling maintenance.
*

3.1.4 Usage notes

* The file is not a read-only file.
* Edit this file directly with your flat file editor of choice, such as
Kate on SLES or WordPad on a Windows platform.
* The file must exist to perform a silent uninstall. The Update
installer wizard reads this file to determine uninstall parameters.
Provide the fully qualified file path to the backup file.
* Save the copy of the options file in the responsefiles directory for
best results.

3.1.5 Example uninstall.txt file

Edit the version of the file that is included in the Update Installer
for WebSphere Software ZIP file. The following example is not guaranteed
to be an accurate representation of the actual file.

So, according to documentation,
1. uninstall process requires you to log in as correct privileges.
2. you need to make sure that you are using correct UpdateInstaller.
3. in general, if the uninstallation fails, may mean that, installation is partial success.
4. check the dependencies.
5. you need to tail app_server_root/logs/update/maintenance_package.uninstall this log for any issues and act accordingly
6. Sometimes, this could be a reason -

Log Rotation

2009-03-02T19:40:00.001+05:30

What is log rotation?

WebSphere Application Server process writes different logs to log different events and errors.
They are
1. Diagnostic Trace

You can set the max file size to say, 20MB, and when ever the file maxes out, the server rotates it taking historical number. Maximum number of Historical Files Specifies the maximum number of rolled over files to keep. If historical number is 1, means that, when trace.log maxes out, it renames the trace.log with trace_currentdate.log and keep on writing into trace.log and so on.

Here is the
${SERVER_LOG_ROOT}/trace.log

2. JVM Logs

These are SystemOut.log and SystemErr.log
You can rotate the with Size and time.

3. Process Logs

These are native_stdout.log and native_stderr.log
If you verbose gc, gc information will be written into native_Stdout.log. If you dump threads on a live process, this is file which dump thread process dumps the thread information. If you have any process related errors, native_stderr.log is the location to find them. You cannot rotate these files.
4. Service Log

httpd

2009-02-27T21:01:00.001+05:30

httpd is the Apache HyperText Transfer Protocol (HTTP) server program. It is designed to be run as a standalone daemon process. When used like this it will create a pool of child processes or threads to handle requests.

In general, httpd should not be invoked directly, but rather should be invoked via apachectl on Unix-based systems

httpd [ -d serverroot ] [ -f config ] [ -C directive ] [ -c directive ] [ -D parameter ] [ -e level ] [ -E file ] [ -k start|restart|graceful|stop ] [ -R directory ] [ -h ] [ -l ] [ -L ] [ -S ] [ -t ] [ -v ] [ -V ] [ -X ]

This term has many definitions and a broad scope. In this document, the meaning of migration is limited to the actions associated with moving Java™ 2 Enterprise Edition (J2EE™) applications (EARs) and Application Server configuration data (such as resources and security settings) from a previous version of Application Server to V6.

Refers to the first step of the two-step migration process. The tool associated with this step will extract information from the previous version of Application Server and store it in a backup directory. This tool can be run by itself from the command line or as part of the migration wizard.

WASPostUpgrade (tool)
Refers to the second step of the two-step migration process. The tool associated with this step will take information from a directory created by the WASPreUpgrade tool and import it into a V6 profile. This tool can be run by itself from the command line or as part of the migration wizard.

Backup directory
Refers to a directory structure created by the WASPreUpgrade tool that contains all the information necessary for migration from the previous version of Application Server.

Migration wizard
Refers to the graphical user interface (GUI) that interactively performs the migration. This GUI tool performs the WASPreUpgrade and WASPostUpgrade steps.

FirstSteps (tool)
Tool provided in V6 to simplify and organize many actions that customers may wish to perform with a newly installed system. It can be found in the firststeps directory under each profile and can be used to launch the migration wizard.

Profiles
This concept expands on the idea of "instances" in V5. It refers to the collection of all the configuration data for an Application Server in V6. Application Server V6 provides for multiple profiles with only one install of the binaries. A single profile is required as the destination for the data being migrated from a previous version. (See Installing Application Server V6.)

Cell
Refers to the collection of one or more nodes controlled by a single deployment manager.

Federate or Federated
Refers to the action of adding a node to a cell; also refers to a node that is part of a cell. This term has been expanded to also refer to a node in a multi-node V4 domain.

Deployment manager profile (dmgr profile)
This profile acts as the deployment manager, and is the destination for the migration of the V5 deployment manager, and as a new deployment manager for V4 migrations. There can be only one deployment manager profile for each cell.

Standalone or Application Server profile
Refers to a profile that is analogous to a single node install of Application Server. This type of profile is the destination for the migrations of a node either in a cell or not in a cell.

Clusters
This term replaces the idea of ServerGroups from V4. Clusters are sets of servers that are used for distributing workload within a cell.

security.xml file is corrupted

2009-02-09T12:46:00.000+05:30

If security.xml file is corrupted how will restore it?
First, what is file corruption?
Corrupted files are files that suddenly become inoperable or unusable. There are several reasons why a file may become corrupted. In some cases, it is possible to recover and fix the corrupted file, while at other times it may be necessary to delete the file and replace it with an earlier saved version.

What are the chances of security.xml becoming corrupted? There are chances for any config file to become corrupted.

Things to understand:-
1. How to avoid this?
2. What to do when this happens?

1. How to avoid this?
When you plan to edit Security.xml or any configuration file, better to take a hard copy back up or run backupConfig script. Hard copy backup, cp file as security_bak.xml, then make make changes to security.

2. What to do when this happens?
Say, on 5th, Tuesday, Feb you made changes to your security, it got fat fingured or corrupted, goto your system admin, revert it back to last working copy.
I would do like this. I would talk to my system admin and ask him to load security.xml from lastnights backup. We at our office, have nightly backups and weekly backups. We retain a months historical backups.

OR - If you know your security model completely, you can manually goto security.xml file, set security to false. save and recycle your server. It sets secutiy to false means no security. Now, set your security again.

Again, When will you modify security.xml? This is not an every day task. You will edit your security at the time of setting up new installation, or when you have a change in LDAP info or, when there is a need to add a new user or group etc. So, its always a good practice to take security.xml backup before you modify it.

There is even a better way to do this, specially in Production Environments. Let your versioning system take care of it. Meaning, check in your configuration into a version control system. If you make any change, it can be tracked.

Backups in WebSphere

2009-02-08T19:25:00.000+05:30

How we take backups in WebSphere?
To know this one should understand what is backup?, how it can be done?, what to backup?, when to backup?.
What is backup? A Backup is a routine runs everyday/week/month per your schedule, takes a copy of the file system or Snapshot of entire OS and so on.
How it can be done?
This is done a special group called System Administrators. They may use a specific software and schedule backup task, like Veritas NetBackup. When will the scheduler runs? Depends on the enterprise backup policy. It can a nightly backups, or over the weekend and so on.
Backup in view of WebSphere - One can backup WebSphere Configuration time to time or as and when required.
How to take Backup in WebSphere?
WebSphere supplies a command called backupConfig
backupConfig.sh backup_file [options]where backup_file specifies the file to which the backup is written. If you do not specify one, a unique name is generated.
Options
-nostop -quiet -logfile logfile_name -profileName profile_name -replacelog -trace -username user_name -password password -help -?

nostop
Tells the backupConfig command not to stop the servers before backing up the configuration
-quiet
Suppresses the progress information that the backupConfig command prints in normal mode
-logfile file_name
Specifies the location of the log file to which trace information is written
By default, the log file is named backupConfig.log and is created in the logs directory.

-profileName profile_name
Defines the profile of the application server process in a multi-profile installation
The -profileName option is not required for running in a single-profile environment. The default for this option is the default profile.

-replacelog
Replaces the log file instead of appending to the current log
-trace
Generates trace information into the log file for debugging purposes
-username user_name
Specifies the user name for authentication if security is enabled in the server; acts the same as the -user option
-user user_name
Specifies the user name for authentication if security is enabled in the server; acts the same as the -username option
-password password
Specifies the password for authentication if security is enabled in the server
-help
Prints a usage statement
-?
Prints a usage statement

Credentials Exception

2009-01-31T02:14:00.000+05:30

This is a very common error you get when you access Workplace.

Description

Error Message:
Credentials Exception

Exception Class:
com.filenet.wcm.toolkit.util.WcmException

There could be more than one reason for getting this exception. If you see something like this in the Error Stack Trace -

"Caused by: org.omg.CORBA.COMM_FAILURE: CAUGHT_EXCEPTION_WHILE_CONFIGURING_SSL_CLIENT_SOCKET: JSSL0080E: javax.net.ssl.SSLHandshakeException - The client and server could not negotiate the desired level of security. Reason: com.ibm.jsse2.util.h: No trusted certificate found vmcid: 0x49421000 minor code: 70 completed: No " which leads to the hand shake failure between Content Engine and Application Engine.

Lets first understand the architecture.

Application Engine comes with a J2EE application called Workplace to be hosted on an application server say, WebSphere. Workplace is a fontend window for your FileNet System, where you can have process configuration, workflow management, initiating workflows, search designs and so on. So, Workplace alone is a J2EE app unless you configure and point to your process engine, content engine and so on.

In FileNet version 4.0, Content Engine is also a J2EE application. So this has to be deployed on, say, WebSphere.

The Workplace's authentication is carried out through Content Engine. Meaning, When you access workplace, workplace throws you a page to authenticate, the credentials what you give are first passed to Content Engine, and the Content Engine, sends a query to LDAP and so on. As soon as it gets your Authentication and Authorization, it passes response to workplace. And workplace knows what to show you with your set of credentials.

So, AE communicates with CE on a specific port and with specific set of parameters. It needs Security check. If you do not implement SSL Handshake between your AE and CE this is the thing whats going to happen: AE takes your login and password from the browser, tries to pass the info to CE, CE App Server checks the incoming request for its Cert info. If it is a trusted request, it allows the request to reach its service methods, otherwise, it rejects the request, and your FileNet API, com.filenet.wcm.toolkit.util.WcmException catches that error and throws this Error Message "Credentials Exception".

How to deal with it?

Keeping FileNEt 4, WAS 6.1.xx versions in mind -

You need to make sure SSL Fruitful Handshake to happen between AE and Ce, meaning you need to make sure CE trusts AE to access its resources.

In WAS 6.1.xx, Trust stores are no more in WAS_PROFILE_HOME/etc but in WAS_PROFILE_HOME/config/cells/cellname/nodes/nodename. The Default trust store is trust.p12

So you need to open this guy, export as a crm file. Do this on AE and CE too.

Meaning, Add CE arm file to AE Trust Store and Add AE arm file to CE Trust store.

You can bounce all the services and recycle temp.

activity.log

2008-12-23T01:34:00.002+05:30

The application server creates the activity.log file from the activity of the various WebSphere Application Server components. you cannot read this log with a text reader. You ca use this script called, showlog under appserver root.
Ex.,
./WAS_INST_ROOT/bin/showlog PATH_TOACTIVITY_LOG/activity.log
like this
websphe: /software/opt/IBM/WebSphere/AppServer/bin
$ ./showlog ../profiles/AppSrv*/logs/activity.log
This displays ur activity log something like this, just as a sample:

How can we configure Remote Plugin?

2008-12-02T23:59:00.003+05:30

This is the procedure
Machine A: WAS
Machine B: IHS
Thumb Rule: Install Plugins on IHS Machine and propagrate them to WAS.
Procedure
Machine A : Install WAS.
Machine B: Install IHS
Machine B : Install Plugins: In the installation process, you have to select remote WAS, and name for ur webserverconfig, say webserver1. After installation, in the IHS_INST/conf/httpd.conf check for IBM Module entry and Plugin installation paths
Goto the plugin installation path/bin
Check for configurewebserver1.sh/bat
Now,
Copy that file, configurewebserver1.sh/bat to WAS box, that is Machine A. The file contains this info.
./wsadmin.sh -f configureWebserverDefinition.jacl webserver1 IHS '/software/IBM/IHS' '
/software/IBM/IHS/conf/httpd.conf' 7700 MAP_ALL '/software/IBM/Plugins' unmanage
d webserver1 hostname solaris
(This is an example, 7700 is port number.)
If you already have enabled global security on WAS, you need to add -username adminusername and -password hispassword at the end of the above script.

Then run the script.

Which creates a WebServer definition in the AppServer.

U need to configure WAS to remote admin WebServer.

configuration change when fedarated

2008-12-02T23:41:00.003+05:30

1. what are all configuration files got changed when we add a node into cell?

When you federate, dmgr takes control of ur federated node. so, it copys DMGRCell into ur node, and pushes ur node info into dmgrcell.

2. What are server.xml and serverindex.xml?

Server.xml is an xml file :). Which contains the information needed for your JVM, like, ur jvm name, clustername, services, properties, threadpoolsettings, process definitions, components and so on
serverindex.xml :
This is the file whoch holds : host name info, deployed application info, ur app server ports info, etc

3. what is FFDC?

FFDC - First Failure Data Capture.
WebSphere Application Server V6 includes a feature called First Failure Data
Capture (FFDC). The FFDC feature runs in the background and collects events
and errors that occur during WebSphere Application Server runtime. The
information that it collects are written to log files in the
/profiles//logs/ffdc directory.

Maintenance Packs Info

2008-11-10T20:44:00.001+05:30

How to check for interim packs, APARs covered in installated Fix Packs or Refresh Packs?
WAS_INST_ROOT/properties/version/update/backup
This the place holder for all the fix packs, interim fix packs if u have install them seperately, refresh packs and so on.
Here you see the following files along with .pak files
update.status.xml
maintenanceStack.xml
maintenanceHistory.xml
If you are looking for a specific APAR, The best way to do it is
grep for that apar in this file maintenanceHistory.xml.
maintenanceStack.xml lists all the apars.

truss

2008-09-26T20:56:00.002+05:30

truss is a command to trace system calls and signals

SYNOPSIS
truss [-fcaeildDE] [- [tTvx] [!] syscall ,...]
[- [sS] [!] signal ,...] [- [mM] [!] fault ,...]
[- [rw] [!] fd ,...]
[- [uU] [!] lib ,... : [:] [!] func ,...]
[-o outfile] command | -p pid[/lwps]...

DESCRIPTION
The truss utility executes the specified command and produces a trace ofthe system calls it performs, the signals it receives, and the machine faults it incurs. Each line of the trace output reports either the fault or signal name or the system call name with its arguments and return value(s).
System call arguments are displayed symbolically when possible using defines from relevant system headers. For any path name pointer argument, the pointed-to string is displayed.
Error returns are reported using the error code names described in intro(3). If, in the case of an error, the kernel reports a missing privilege, a privilege name as described in privileges(5) is reported in square brackets ([
]) after the error code name.
Optionally (see the -u option), truss also produce an entry/exit trace of user-level function calls executed by the traced process, indented to indicate nesting.

Why to know about truss?

In the day today admin job, you may want to see what a process is doing? or you may want to check an installation process. Or ur installation process is failing, you want check whats going on. You use truss in such conditions.

Some examples:

truss -p pid
gives you that specific pids systemcalls
$ truss -p 883
/14: lwp_cond_wait(0x0193BFF8, 0x0193BFE0, 0xD287F710, 0) Err#62 ETIME

883 is a WebSphere pid.

$ truss -o example.out -p 883
truss traces pid 883 and outputs to example.out

$truss -o example.out install.sh
install.sh is an installer of a software. truss traces the installation process's system calls and outputs to example.out

find, grep

2008-09-18T19:53:00.003+05:30

find:
NAME
find - find files
SYNOPSIS
/usr/bin/find [-H -L] path... expression
/usr/xpg4/bin/find [-H -L] path... expression
DESCRIPTION
The find utility recursively descends the directory hierar- chy for each path seeking files that match a Boolean expres- sion written in the primaries given below.
find is able to descend to arbitrary depths in a file hierarchy and does not fail due to path length limitations (unless a path operand specified by the application exceeds PATH_MAX requirements).

Examples :
find . -name "bla.log" -print
This command will search in the current directory and all sub directories for a file named bla.log.
Note: The -print option will print out the path of any file that is found with that name. In general -print wil print out the path of any file that meets the find criteria.

find /usr/src -not $ -name "*,v" -o -name ".*,v" $ '{}' \; -print
This command will search in the /usr/src directory and all sub directories. All files that are of the form '*,v' and '.*,v' are excluded. Important arguments to note are:
-not means the negation of the expression that follows
$ means the start of a complex expression.
$ means the end of a complex expression.
-o means a logical or of a complex expression. In this case the complex expression is all files like '*,v' or '.*,v'
find . -exec grep "size" '{}' \; -print
This command will search in the current directory and all sub directories. All files that contain the string will have their path printed to standard output.
grep:

NAME
grep - search a file for a pattern
SYNOPSIS
/usr/bin/grep [-bchilnsvw] limited-regular-expression [filename...]
/usr/xpg4/bin/grep [-E -F] [-c -l -q] [-bhinsvwx] -e pattern_list... [-f pattern_file]... [file...]
/usr/xpg4/bin/grep [-E -F] [-c -l -q] [-bhinsvwx] [-e pattern_list...] -f pattern_file... [file...]
/usr/xpg4/bin/grep [-E -F] [-c -l -q] [-bhinsvwx] pattern [file...]
DESCRIPTION
The grep utility searches text files for a pattern and prints all lines that contain that pattern. It uses a com- pact non-deterministic algorithm.
Be careful using the characters $, *, [, ^, , (, ), and \ in the pattern_list because they are also meaningful to the shell. It is safest to enclose the entire pattern_list in single quotes '...'.
If no files are specified, grep assumes standard input. Nor- mally, each line found is copied to standard output. The file name is printed before each line found if there is more than one input file.
/usr/bin/grep The /usr/bin/grep utility uses limited regular expressions like those described on the regexp(5) manual page to match the patterns.
/usr/xpg4/bin/grep The options -E and -F affect the way /usr/xpg4/bin/grep interprets pattern_list. If -E is specified, /usr/xpg4/bin/grep interprets pattern_list as a full regular expression (see -E for description). If -F is specified, grep interprets pattern_list as a fixed string. If neither are specified, grep interprets pattern_list as a basic regular expression as described on regex(5) manual page.

Example:
U want to find a string "size" in a folder and in its subfloders. This is the example
grep -i size `find . name *.* -print`

Grep can be used in so many ways and for so many reasons.
If I want to check the java processes
ps -ef grep java
If I want to check java processes owned by a particular user
ps -ef grep java grep websphe

If I want to check network statistics and specifically for a specific host
netstat -a grep hostname
..
netstat -a grep 8080

and so on.

cp

2008-09-09T19:23:00.002+05:30

U might know this
But, just FYI

If you want to copy a file in UNIX, cp is the command
man cp gives the following info.
cp - copy files

SYNOPSIS /usr/bin/cp [-fip@] source_file target_file
/usr/bin/cp [-fip@] source_file... target
/usr/bin/cp -r -R [-H -L -P] [-fip@] source_dir... target
/usr/xpg4/bin/cp [-fip@] source_file target_file
/usr/xpg4/bin/cp [-fip@] source_file... target
/usr/xpg4/bin/cp -r -R [-H -L -P] [-fip@] source_dir... target

Usage Example:

$ mkdir testcp
$ mkdir testcpdest
$ cd testcp
$ touch x1.txt
$ cd ..
$ cp -r testcp testcpdest

I made a dir called testcp (which is the source dir)
I made another dir called testcpdest (destination dir)
I have touched a file x1.txt in testcp
I have copied testcp to testcpdest with files using cp -r meaning copy recursively.

Another ex.,
I have a file like this
-rw-r--r-- 1 websphe websphe 13593 Mar 18 11:53 n1.log
I want to cp it to n2.log with the same time stamp and same uid,gid permissions. This is the way
cp -p n1.log n2.log
n2.log will have same time stamp and other info as n1.log
-rw-r--r-- 1 websphe websphe 13593 Mar 18 11:53 n2.log
-rw-r--r-- 1 websphe websphe 13593 Mar 18 11:53 n1.log

umask

2008-08-05T22:06:00.002+05:30

umask stands for user file creation mode mask.
777 stands for rwxrwxrwx. first set of rwx is for user, second set of rwx for group and last set is for others. to know what umask u have, at the prompt type umask, which will return a value, say 022.
What does that mean o22?
Its simple.
777-022=755.
umask 022 = rwxr-xr-x, meaning, user has all permissions, group has read and execute, others have read and execute.
To understand umask in permissions mode try this command, umask -S
for example
$ umask
022
$ umask -S
u=rwx,g=rx,o=rx

proxy server

In an enterprise that uses the Internet, a proxy server is a server that acts as an intermediary between a workstation user and the Internet so that the enterprise can ensure security, administrative control, and caching service. A proxy server is associated with or part of a gateway server that separates the enterprise network from the outside network and a firewall server that protects the enterprise network from outside intrusion.
A proxy server receives a request for an Internet service (such as a Web page request) from a user. If it passes filtering requirements, the proxy server, assuming it is also a cache server, looks in its local cache of previously downloaded Web pages. If it finds the page, it returns it to the user without needing to forward the request to the Internet. If the page is not in the cache, the proxy server, acting as a client on behalf of the user, uses one of its own IP addresses to request the page from the server out on the Internet. When the page is returned, the proxy server relates it to the original request and forwards it on to the user.

To the user, the proxy server is invisible; all Internet requests and returned responses appear to be directly with the addressed Internet server. (The proxy is not quite invisible; its IP address has to be specified as a configuration option to the browser or other protocol program.)

An advantage of a proxy server is that its cache can serve all users. If one or more Internet sites are frequently requested, these are likely to be in the proxy's cache, which will improve user response time. In fact, there are special servers called cache servers. A proxy can also do logging.

The functions of proxy, firewall, and caching can be in separate server programs or combined in a single package. Different server programs can be in different computers. For example, a proxy server may in the same machine with a firewall server or it may be on a separate server and forward requests through the firewall.

gateway

A gateway is a network point that acts as an entrance to another network. On the Internet, a node or stopping point can be either a gateway node or a host (end-point) node. Both the computers of Internet users and the computers that serve pages to users are host nodes. The computers that control traffic within your company's network or at your local Internet service provider (ISP) are gateway nodes.
In the network for an enterprise, a computer server acting as a gateway node is often also acting as a proxy server and a firewall server. A gateway is often associated with both a router, which knows where to direct a given packet of data that arrives at the gateway, and a switch, which furnishes the actual path in and out of the gateway for a given packet.

node

In a network, a node is a connection point, either a redistribution point or an end point for data transmissions. In general, a node has programmed or engineered capability to recognize and process or forward transmissions to other nodes.

router

In packet-switched networks such as the Internet, a router is a device or, in some cases, software in a computer, that determines the next network point to which a packet should be forwarded toward its destination. The router is connected to at least two networks and decides which way to send each information packet based on its current understanding of the state of the networks it is connected to. A router is located at any gateway (where one network meets another), including each point-of-presence on the Internet. A router is often included as part of a network switch.

A router may create or maintain a table of the available routes and their conditions and use this information along with distance and cost algorithms to determine the best route for a given packet. Typically, a packet may travel through a number of network points with routers before arriving at its destination. Routing is a function associated with the Network layer (layer 3) in the standard model of network programming, the Open Systems Interconnection (OSI) model. A layer-3 switch is a switch that can perform routing functions.

An edge router is a router that interfaces with an asynchronous transfer mode (ATM) network. A brouter is a network bridge combined with a router.

For home and business computer users who have high-speed Internet connections such as cable, satellite, or DSL, a router can act as a hardware firewall. This is true even if the home or business has only one computer. Many engineers believe that the use of a router provides better protection against hacking than a software firewall, because no computer Internet Protocol address are directly exposed to the Internet. This makes port scans (a technique for exploring weaknesses) essentially impossible. In addition, a router does not consume computer resources as a software firewall does. Commercially manufactured routers are easy to install, reasonably priced, and available for hard-wired or wireless networks.

switch

In a telecommunications network, a switch is a device that channels incoming data from any of multiple input ports to the specific output port that will take the data toward its intended destination. In the traditional circuit-switched telephone network, one or more switches are used to set up a dedicated though temporary connection or circuit for an exchange between two or more parties. On an Ethernet local area network (LAN), a switch determines from the physical device (Media Access Control or MAC) address in each incoming message frame which output port to forward it to and out of. In a wide area packet-switched network such as the Internet, a switch determines from the IP address in each packet which output port to use for the next part of its trip to the intended destination.

In the Open Systems Interconnection (OSI) communications model, a switch performs the layer 2 or Data-Link layer function. That is, it simply looks at each packet or data unit and determines from a physical address (the "MAC address") which device a data unit is intended for and switches it out toward that device. However, in wide area networks such as the Internet, the destination address requires a look-up in a routing table by a device known as a router. Some newer switches also perform routing functions (layer 3 or the Network layer functions in OSI) and are sometimes called IP switches.

On larger networks, the trip from one switch point to another in the network is called a hop. The time a switch takes to figure out where to forward a data unit is called its latency. The price paid for having the flexibility that switches provide in a network is this latency. Switches are found at the backbone and gateway levels of a network where one network connects with another and at the subnetwork level where data is being forwarded close to its destination or origin. The former are often known as core switches and the latter as desktop switches.

In the simplest networks, a switch is not required for messages that are sent and received within the network. For example, a local area network may be organized in a Token Ring or bus arrangement in which each possible destination inspects each message and reads any message with its address.

Circuit-Switching version Packet-Switching
A network's paths can be used exclusively for a certain duration by two or more parties and then switched for use to another set of parties. This type of "switching" is known as circuit-switching and is really a dedicated and continuously connected path for its duration. Today, an ordinary voice phone call generally uses circuit-switching.

Most data today is sent, using digital signals, over networks that use packet-switching. Using packet-switching, all network users can share the same paths at the same time and the particular route a data unit travels can be varied as conditions change. In packet-switching, a message is divided into packets, which are units of a certain number of bytes. The network addresses of the sender and of the destination are added to the packet. Each network point looks at the packet to see where to send it next. Packets in the same message may travel different routes and may not arrive in the same order that they were sent. At the destination, the packets in a message are collected and reassembled into the original message.

layer 2

Layer 2 refers to the Data Link layer of the commonly-referenced multilayered communication model, Open Systems Interconnection (OSI). The Data Link layer is concerned with moving data across the physical links in the network. In a network, the switch is a device that redirects data messages at the layer 2 level, using the destination Media Access Control (MAC) address to determine where to direct the message.

The Data-Link layer contains two sublayers that are described in the IEEE-802 LAN standards:

->Media Access Control (MAC) sublayer
->Logical Link Control (LLC) sublayer
->The Data Link layer ensures that an initial connection has been set up, divides output data into data frames, and handles the acknowledgements from a receiver that the data arrived successfully. It also ensures that incoming data has been received successfully by analyzing bit patterns at special places in the frames.

bridge

In telecommunication networks, a bridge is a product that connects a local area network (LAN) to another local area network that uses the same protocol (for example, Ethernet or Token Ring). You can envision a bridge as being a device that decides whether a message from you to someone else is going to the local area network in your building or to someone on the local area network in the building across the street. A bridge examines each message on a LAN, "passing" those known to be within the same LAN, and forwarding those known to be on the other interconnected LAN (or LANs).

In bridging networks, computer or node addresses have no specific relationship to location. For this reason, messages are sent out to every address on the network and accepted only by the intended destination node. Bridges learn which addresses are on which network and develop a learning table so that subsequent messages can be forwarded to the right network.

Bridging networks are generally always interconnected local area networks since broadcasting every message to all possible destinations would flood a larger network with unnecessary traffic. For this reason, router networks such as the Internet use a scheme that assigns addresses to nodes so that a message or packet can be forwarded only in one general direction rather than forwarded in all directions.

A bridge works at the data-link (physical network) level of a network, copying a data frame from one network to the next network along the communications path.

A bridge is sometimes combined with a router in a product called a brouter.

firewall

A firewall is a set of related programs, located at a network gateway server, that protects the resources of a private network from users from other networks. (The term also implies the security policy that is used with the programs.) An enterprise with an intranet that allows its workers access to the wider Internet installs a firewall to prevent outsiders from accessing its own private data resources and for controlling what outside resources its own users have access to.
Basically, a firewall, working closely with a router program, examines each network packet to determine whether to forward it toward its destination. A firewall also includes or works with a proxy server that makes network requests on behalf of workstation users. A firewall is often installed in a specially designated computer separate from the rest of the network so that no incoming request can get directly at private network resources.

There are a number of firewall screening methods. A simple one is to screen requests to make sure they come from acceptable (previously identified) domain name and Internet Protocol addresses. For mobile users, firewalls allow remote access in to the private network by the use of secure logon procedures and authentication certificates.

A number of companies make firewall products. Features include logging and reporting, automatic alarms at given thresholds of attack, and a graphical user interface for controlling the firewall.

Computer security borrows this term from firefighting, where it originated. In firefighting, a firewall is a barrier established to prevent the spread of fire.

reverse proxy server

A reverse proxy server is a proxy server that relays connection requests for inbound network traffic

Web Proxies

A proxy server is a gateway for users to the Web at large. Users configure the proxy in their browser settings, and all HTTP requests are routed via the proxy. Proxies are typically operated by ISPs and network administrators, and serve several purposes: for example,

->to speed access to the Web by caching pages fetched, so that popular pages don't have to be re-fetched for every user who views them.
->to enable controlled access to the web for users behind a firewall.
->to filter or transform web content.

Reverse Proxies

A reverse proxy is a gateway for servers, and enables one web server to provide content from another transparently. As with a standard proxy, a reverse proxy may serve to improve performance of the web by caching; this is a simple way to mirror a website. But the most common reason to run a reverse proxy is to enable controlled access from the Web at large to servers behind a firewall.

The proxied server may be a webserver itself, or it may be an application server using a different protocol, or an application server with just rudimentary HTTP that needs to be shielded from the web at large. Since 2004, reverse proxying has been the preferred method of deploying JAVA/Tomcat applications on the Web, replacing the old mod_jk (itself a special-purpose reverse proxy module).

The Funda of Reverse Proxy - The web server will service any HTTP or HTTPS requests and CAN operate in reverse proxy mode. In this mode, the destination server will be hidden from the user and all requests will appear as though they are being fulfilled at the proxy. The web agent acts as a filter for requests directed to the proxy server. The web agent will intercept all requests directed to the web server where it is loaded and will communicate with SiteMinder to determine if the requested resource is protected. If the resource is protected, the web agent will challenge the user to provide an authorised set of credentials. Otherwise, the request is release to the web server for processing.

Question 4: A WSAS administrator notices the following error in the SystemOut.log:

javax.jms.InvalidDestinationException:
MQJMS0003: Destination not understood or no longer valid.

Which of the following could have caused this error?

A. The JMS destination requires IIOP protocol for access. The JMS client is using the default JMS message protocol.
B. The JMS destination is running on a non-WebSphere environment.
C. The JMS destination was accidentally deleted.
D. The JNDI binding to the destination was changed.
E. The JMS destination is listening on a non standard TCP port.
me: http://www-1.ibm.com/support/docview.wss?uid=swg1IY60708
PROBLEM SUMMARY:
This problem is caused by using JMS interfaces to access MQ JMS
classes (i.e. casting a com.ibm.mq.MQQueue to a
javax.jms.Queue).

The use of an (instanceof MQQueue) test was returning false
when an MQQueue object had been cast as a javax.jms.Queue. The
logic then treated this as an invalid object, and threw an
InvalidDestinationException.

Server not starting after enabling Security with exceptions WSVR0003E and ADMC0019E
Technote (FAQ)

Problem
After enabling security, the application server does not start up (in this case, DMGR and nodeAgent comes up but not the servers).

Cause
When security is enabled, the SOAP connector needs to obtain the Secure Sockets Layer (SSL) configuration to intialize the SSL server socket. The error occurs when no SSL configuration is specified for the secure SOAP connector.
The error stack would look like this:

Question 43: A WSAS administrator notices frequent StaleConnectionException from a JDBC WSAS Version 4 resource. Which of the following are valid causes for this problem?

A. The JDBC database is reaping the connection.
B. The JDBC connection orphan timeout is too small.
C. The TCP keepalive timeout for the JDBC connection was exceeded.
D. A transaction was rolled back on the JDBC connection and thus marked as stale.
E. A duplicate JDBC connection was established causing the old connection to become stale.

me: The application tries to get a connection and fails, as when the database is not started.
A connection is no longer usable because of a database failure. When an application tries to use a previously obtained connection, the connection is no longer valid. In this case, all connections currently in use by the application can get this error when they try to use the connection.
The connection is orphaned (because the application had not used it in at most two times the value of the unused timeout setting) and the application tries to use the orphaned connection. This case applies only to Version 4.0 data sources.
The application tries to use a JDBC resource, such as a statement, obtained on a stale connection.
A connection is closed by the Version 4.0 data source auto connection cleanup and is no longer usable. Auto connection cleanup is the standard mode in which connection management operates. This mode indicates that at the end of a transaction, the transaction manager closes all connections enlisted in that transaction. This enables the transaction manager to ensure that connections are not held for excessive periods of time and that the pool does not reach its maximum number of connections prematurely.

Security role to user and group mapping
Use this page to map security roles to users. You can map roles to specific users, to specific groups, or to different categories.
To view this administrative console page, click Applications > Install New Application. While running the Application Installation Wizard, prompts display to help you map security roles to users or groups. To change role to user or group mappings for deployed applications, click Applications > Enterprise Application > deployed_application > Security roles to user/group mapping.
Everyone
Specifies to map roles to everyone. Mapping a role to everyone means that anyone can access resources protected by this role, and essentially, there is no security.
-D
3. A WAR file in an enterprise application has been changed. How can a system administrator update it on the server with a minimal amount of work?
A. Re-package the EAR file using Application Server Toolkit then use the "Update -> Full application" function on the administrative console.
B. Use the "Update -> Single file" function of the Administrative console to replace the WAR file.
C. Use the "Update -> Single module" of the Administrative console to replace the WAR file.
D. Use the "Update -> Partial application" of the Administrative console to replace the WAR file.
Single module
Under Update options, specifies to replace a module in or add a module to an installed application. The module can be a Web module (.war file), enterprise bean module (EJB .jar file), or resource adapter module (connector .rar file).
After selecting this option, specify whether the module is on a local or remote file system and the full path name of the module. The path provides the location of the updated module before installation. For information on Local file system and Remote file system, refer to the description of Full application above.
-C
If you select Update, you will be given with four options
Full Application
Single Module
Single File
Partial Application
Full Application :
Select this option to replace the enterprise archive (*.ear) file for an installed application. The uploaded enterprise archive replaces the existing installed application.
Single module
Select this option to update an existing module or to add a new module to the application. If the relative path to the module matches an existing path to a module in the installed application, the uploaded module replaces the existing module. If the relative path to the module does not exist in the installed application, the uploaded module is added to the application.
Single file
Select this option to update an existing file or to add a new file to the application. If the relative path to the file matches an existing path to a file in the installed application, the uploaded file replaces the existing file. If the relative path to the file does not exist in the installed application, the uploaded file is added to the application.
Partial application
Select this option to update or add several files to an application. Use a valid compressed file format such as .zip or .gzip. The compressed file is unzipped into the installed application directory. If the uploaded files exist in the application with the same paths and file names, the uploaded files replace the existing files. If the uploaded files do not exist, the files are added to the application. You can remove existing files from the installed application by specifying metadata in the compressed file.
4. While performing a node federation, the addNode operation failed. From the following list of options, what would MOST likely induce this failure?
A. The cell already exists
B. The cell's deployment manager is running before the addNode command was run
C. The name of the new node is not unique in the cell
D. The addNode did not specify to carry over the applications
-A
5.Cluster creation requires the system administrator to specify the weight for a cluster member. This weight is significant because it is used in the WebSphere WLM runtime by the:
A. Random scheduling algorithm
B. Round Robin scheduling algorithm
C. Both Random and Round Robin scheduling algorithm
D. Weighted Random algorithm

In the simplest case, the cluster contains only one server definition. In the case in which more than one server is defined, the plug-in will load balance across the defined servers using either a Round Robin or a Random algorithm. The default is Round Robin.
LoadBalanceWeight (zero or one attribute for each Server)
Specifies the weight associated with this server when the plug-in does weighted Round Robin load balancing. The starting value for a server can be any integer between 0 and 20. However, zero should be specified only for a server that is shut down.
The algorithm for this attribute decrements all weights within the server cluster until all weights reach zero. After the weight specified for a particular server reaches zero, no more requests are routed to that server until all servers in the cluster have a weight of zero. After all servers reach zero, the weights for all servers in the cluster are reset and the algorithm starts over.
When a server is shut down, it is recommended that you set the weight for that server to zero. The plug-in can then reset the weights of the servers that are still running, and maintain proper load balancing.
The answer for this is Weighted Round Robin
6. A new JDBC provider is being created in a cell in which the servers run on different operating systems. Which of the following scopes should be used?
A. Cluster scope
B. Server scope
C. Node scope
D. Cell scope
??
7. A system administrator is asked to help explain why a NameNotFoundException is happening while attempting to access an enterprise bean, data source, messaging resource, or other resource. What action would be the LEAST useful to do to explain the problem?
A. Browse the properties of the target object in the administrative console, and verify that the JNDI name it specifies matches the JNDI name the client is using.
B. Browse the properties of the target object in its deployment descriptor, and verify that the JNDI name it specifies matches the JNDI name the client is using.
C. Determine if the object being looked up resides on a server different from the one from which the initial context was obtained since, in this case, the fully qualified name must be used.
D. Use the showNameSpace utility to export the entire JNDI tree to determine if the desired resource is listed.
Incorrect lookup name
If you encounter a NameNotFoundException when trying to access an enterprise bean, data source, messaging resource, or other resource:
Determine the cause of the NameNotFoundException.
Browse the properties of the target object in the administrative console, and verify that the JNDI name it specifies matches the JNDI name the client is using.
If you are looking up an object that resides on a server different from the one from which the initial context was obtained, you must use the fully qualified name.
If access is from another server object such as a servlet accessing an enterprise bean and you are using the default context, not specifying the fully qualified JNDI name, you might get a NameNotFoundException if the object is hosted on a different server.
If access is from a standalone client, it might be that the object you are attempting access is on a server different from the server from which you obtained the initial context.
Use the fully-qualified JNDI name to correct the problem.
If the object is in a single server, the fully-qualified JNDI name is as follows:
cell/nodes/nodeName/servers/serverName/jndiName
Restriction: Objects are not supported in this release.
If the object is on a server cluster, the fully-qualified JNDI name is as follows:
cell/clusters/clusterName/jndiName
-A

WebSphere Administration

I would like to post some information on WebSphere Application Server Administration, starting from How to start, Wherer to Start, Installation Issues, Configuring, Performance Tuning.

-: Installation :-

So, How to install WebSphere 6.0, Base/ND on Windows/Solaris?
Recently I got to install and provide WAS on Solaris Hardware. The requirement was to provide a DEV enviroment for a development team. The demand was to provide WAS 6.0.2.5 on Solaris 10 Hardware. We have license of WAS 6.0.
The installation process I have followed goes like this.
1. Identification of Installation Topology.
2. Preparing the Hardware for Installation.
3. Installation Steps
4. Post Installation Steps.

1. Identification of Installation Topology.
First we need to identify what is the installation topology. Means, How we have to proceed for installation. The scenarios for installation are
* Scenario 1: Single-machine installation of WebSphere Application Server
* Scenario 2: Single-machine installation of WebSphere Application Server and a Web server
* Scenario 3: Two-machine installation of WebSphere Application Server and a Web server
* Scenario 4: Creating multiple profiles that use one installation of WebSphere Application Server
The Demand for my DEV Team matches Secnario 1.

2. Preparing the Hardware for Installation.
Refer this link for this step
http://publib.boulder.ibm.com/infocenter/wasinfo/v6r0/index.jsp?topic=/com.ibm.websphere.base.doc/info/aes/ae/
txml_callappinstall.html

3. Installation Process
You have prepared the OS for the WAS Installation. Now it is the time to install WAS 6.0.
You can do that manually, or you can develop script for this process. Before coming into the details of developing of script or manual installation, you need to know some more things. In Solaris, you cannot see the GUI. Everything will be at the command line and you have to chose non UI installation.
For any software to install, you see different modes of installations, viz. Typical, Custom. When you are installation in the UI Mode, you can select the appropriate option. But, in a non UI mode how will you do that? You have to mention all your properties in a file and give that file, means pass that file to the installation process, called RESPONSE_FILE.
To install WAS on Solaris, you need to select the silent installation process.
These are the steps:
1. Have the path of the software.
For example, a CD_SHARE_SERVER, or media. Or ask your Solaris Admin to give the path. In my case, the Solaris Admin mapped the CD_SHARE_SERVER for me.
2. Prepare the Response file.
You can have the sample response file from the following location.
You can take that modify that.

My responsefile goes like this:
I have stored this as responsefile.base.txt in /myfolder on the server box.

-W silentInstallLicenseAcceptance.value="true"
-P wasProductBean.installLocation="/software/IBM/WebSphere/AppServer"
-W setuptypepanelInstallWizardBean.selectedSetupTypeId="Custom"
-P samplesProductFeatureBean.active="true"
-P javadocsProductFeatureBean.active="true"
-W defaultprofileportspanelInstallWizardBean.WC_defaulthost="9080"

-W defaultprofileportspanelInstallWizardBean.BOOTSTRAP_ADDRESS="2809"
-W defaultprofileportspanelInstallWizardBean.
SOAP_CONNECTOR_ADDRESS="8880"
-W defaultprofileportspanelInstallWizardBean.

-W defaultprofileportspanelInstallWizardBean.SIB_MQ_ENDPOINT_ADDRESS="5558"
-W defaultprofileportspanelInstallWizardBean.
SIB_MQ_ENDPOINT_SECURE_ADDRESS="5578"

-W nodehostandcellnamepanelInstallWizardBean.hostName="bristow"
-W setcellnameinglobalconstantsInstallWizardBean.value="bristowCell01"
-W winservicepanelInstallWizardBean.accountType="localsystem"
-W winservicepanelInstallWizardBean.startupType="manual"
-W winservicepanelInstallWizardBean.userName="websphe"
-W winservicepanelInstallWizardBean.password="admin1"

4. Once you have the response file, it’s the time to actual installation.
Goto the CD_SHARE_PATH or Media Mount, locate WAS6.0 installable folder.
For example
/koppell_cd_share/cd_share/WebSphere/wasv6_base_solsparc
This is my installable folder.
Traverse to WAS folder.
U r at
/koppell_cd_share/cd_share/WebSphere/wasv6_base_solsparc/WAS/
now, issue the command
install -options “/myfolder/responsefile.base.txt” -silent

This silently installs the WAS 6.0.

The another way of doing this writing as shell script like, name it as installer.sh
#!/usr/bin/ksh
MEDIA_DIR=/koppell_cd_share/cd_share/WebSphere/wasv6_base_solsparc
INSTALL_DIR=/software/IBM
RESPONSEFILE=/myfolder/responsefile.base.txt
if [[ ! -f ${MEDIA_DIR}/WAS/install ]]
then
echo "\nCannot find webSphere Install Program"
exit 1
fi

umask 022

echo "\nNow installing websphere..."
${MEDIA_DIR}/WAS/install -options ${RESPONSEFILE} -silent

sleep 15
FOUND=0
while [[$FOUND -eq 0 ]]
do
sleep 5
if [[ `/usr/bin/grep INSTCONFFAIL
${INSTALL_DIR}/WebSphere/AppServer/logs/log.txt /usr/bin/wc -l` -gt 0
]]
then
echo "\nWebSphere install Failed"
FOUND=1
exit 1
fi
if [[ `/usr/bin/grep INSTCONFPARITALSUCCESS
${INSTALL_DIR}/WebSphere/AppServer/logs/log.txt /usr/bin/wc -l` -gt 0
]]
then
echo "\nWebSphere install partial success"
FOUND=1
exit 1
fi
if [[ `/usr/bin/grep INSTCONFSUCCESS
${INSTALL_DIR}/WebSphere/AppServer/logs/log.txt /usr/bin/wc -l` -gt 0
]]
then
echo "\nWebSphere Installation Success"
FOUND=1
fi
done
echo "\nWebSphere products installed SUCCESSFULLY"
exit 0

Hopefully this should work with out any script errors, anyhow, my idea is to give an idea about the script, but not to see the script errors.

5. Post Installation
What Now!! We have installed the Application server. Now, this is the time to check post installation steps. Remeber that, the installation creates a profile for you called default. You can find that at WAS_HOME/profiles directory.

First you need to see the logs
WAS_HOME/logs
check the log.txt.

Goto the WAS_HOME (WAS_HOME is nothing but the Installed path of the WAS). That is /software/IBM/WebSphere/AppServer/profiles/default/bin.
Give this command
$ ivt.sh SERVER_NAME PROFILE_NAME
that is
ivt.sh server1 default
This will tell you whether the installation is successful or not.

I said that the installation will create a default profile for you called “default”. You should know what a profile is and how it can help you.
The WebSphere Application Server profile defines the runtime environment. The profile includes all of the files that the server processes in the runtime environment and can change.

Administration is greatly enhanced when using profiles instead of multiple product installations. Not only is disk space saved, but updating the product is simplified when you maintain only a single set of product core files. Also, creating new profiles is faster and less prone to error than full product installations, allowing a developer to create separate profiles of the product for development and testing.

Now, the WAS is installed. You can access the admin console like this
http://hostName:9060/ibm/console/

If you have planned to have a Web Server, it is the time for you to install it. You do the same steps for installing Web Server. The WAS Supports Apache, IHS, IIS, etc. Pick yous choice of Web Server and proceed for the installation.

After installing the Web Server, You have to install Plugins. This installation will generate plugin-config.xml, which is supposed to be the communication between Web Server and the WAS.

6. Refresh Packs and Fix Packs
As I said, my goal is to install WAS 6.0.2.5 and I have installed only WAS6.0. How to bring the installation to 6.0.2.5? For that, you need to goto ibm and download fix packs and refresh packs. What I did is, first I have installed Refresh Pack 2 and on that I have installed a fix pack.
Note: Before applying fix packs or refresh packs, make sure that you have stopped the server.
This raises a question, How to install these fix packs and refresh packs?
Note: As a good practice, before installing any fix packs or patches, or refresh packs, take a backup of the existing configuration. How to do that?
Goto WAS_HOME/profiles/default/bin
issue this command
./stopServer.sh server1
This will stops the server.

Now, goto the WAS_HOME/bin
$./backupConfig.sh
This will take the backup of the server including the default profile.
The back will be stored as WebSphereConfig_YYYY_MM_DD.zip
Again it is a good practice to have separate folder for backups, and this will be according to the company policy.

I have first downloaded refresh pack 2. That comes as a tar.
Download the tar 6.0-WS-WAS-SolarisSparc-RP0000002.tar into the WAS_HOME. Untar it like this.
tar -xvf 6.0-WS-WAS-SolarisSparc-RP0000002.tar

This will create a folder updateinstaller in the WAS_ROOT.
In the updateinstaller folder, search for responsefiles subfolder.
You can see install.txt and uninstall.txt.
These two are responsefiles.
Edit the install.txt for your environment. I have edit that like this

-W maintenance.package="/software/IBM/WebSphere/updateinstaller
/maintenace/6.0-WS-WAS-SolarisSparc-RP0000002.pak"
-W product.location="/software/IBM/WebSphere/AppServer"
-W update.type="install"

Goto the /WAS_HOME/bin
at the command prompt issue this command
$setupCmdLine.sh
Now, again come to the updateinstaller folder and at the command prompt issue this
$ ./update -options responsefiles/install.txt -silent
This silently installs the refresh pack.
You have to check whether that installer installed properly or not. For that you need to goto the logs.
/WAS_HOME/logs/update/
check all the logs in all the foldrs in this folder.

Once you are done with the confirmation INSTCONFSUCCESS,
goto WAS_HOME/bin/
$./versionInfo.sh
This will give you the version of the current installation.
Now, start the server
WAS_HOME/profiles/default/bin
$./startServer.sh server1
If the installation is successful, the server will start.

Now, I have to install Fix Pack.
For that the procedure is same.
First I have cleaned up updateinstaller.
By the way, how to remove a folder which has files in that in Solaris?
rm -r updateinstaller
This is the command.
Now, the folder is deleted. Again download the fix pack 6.0.2-WS-WAS-SolarisSparc-FP0000005.tar
Stop the server as usual. And take the back up of the server as above.
Prepare the install.txt response file and install the fix pack in the silent mode.
Uff!!! Long process!!
Now, check the versionInfo of the product.

Start the server, access the Admin Console. You will see the 6.0.2.5 admin console.

7. Profiles:

As I said, the installation will create a default profile. If you want you can create your own profile depending on the need.

I will discuss the process of creating your own profile.

There is a command in WAS to create a profile.

In Solaris, the can be created silently using pctSolaris.bin

pctSolaris.bin is the profile creation tool. How to use it and where to find it.

Goto WAS_HOME/bin/ProfileCreator

You will see

pct.jar
responsefile.BaseProfile..txt

pctSolaris.bin

So, to install a profile u can have a responsefile and use pctSolaris.bin to create it. There is another way of create profile. That is by using wasprofile.sh.

simply call wasprofile.sh at the command prompt, it will give you the available modes : create, augment, delete, etc....

The syntax of creating profile using wasprofile.sh

wasprofile.sh -create -profileName -profilePath -templatePath -nodename -cellName -hostName

Let us see how to create a profile using pctSolaris.bin

First prepare a responsefile for the profile.

My response file goes like this

# Profile Name devirs-
W silentInstallLicenseAcceptance.value="true"

-W profilenamepanelInstallWizardBean.profileName="devirs"
-W profilenamepanelInstallWizardBean.isDefault="false"
-P installLocation="/software/IBM/WebSphere/AppServer/profiles/devirs"
# Node name
-W nodehostnamepanelInstallWizardBean.nodeName="bristowdevirsNode"
# Host name
-W nodehostnamepanelInstallWizardBean.hostName="bristow"
# Cell name
-W setnondmgrcellnameinglobalconstantsInstallWizardBean.value="bristowdevirsCell"
# Port value assignment
-W pctdefaultprofileportspanelInstallWizardBean.WC_defaulthost="9081"
-W pctdefaultprofileportspanelInstallWizardBean.WC_adminhost="9063"
-W pctdefaultprofileportspanelInstallWizardBean.WC_defaulthost_secure="9446"
-W pctdefaultprofileportspanelInstallWizardBean.WC_adminhost_secure="9044"
-W pctdefaultprofileportspanelInstallWizardBean.BOOTSTRAP_ADDRESS="2899"
-W pctdefaultprofileportspanelInstallWizardBean.SOAP_CONNECTOR_ADDRESS="8881"
-W pctdefaultprofileportspanelInstallWizardBean.
SAS_SSL_SERVERAUTH_LISTENER_ADDRESS="9406"
-W pctdefaultprofileportspanelInstallWizardBean.
CSIV2_SSL_SERVERAUTH_LISTENER_ADDRESS="9407"
-W pctdefaultprofileportspanelInstallWizardBean.
CSIV2_SSL_MUTUALAUTH_LISTENER_ADDRESS="9408"
-W pctdefaultprofileportspanelInstallWizardBean.ORB_LISTENER_ADDRESS="9102"
-W pctdefaultprofileportspanelInstallWizardBean.DCS_UNICAST_ADDRESS="9355"
-W pctdefaultprofileportspanelInstallWizardBean.SIB_ENDPOINT_ADDRESS="7279"
-W pctdefaultprofileportspanelInstallWizardBean.
SIB_ENDPOINT_SECURE_ADDRESS="7289"
-W pctdefaultprofileportspanelInstallWizardBean.SIB_MQ_ENDPOINT_ADDRESS="5588"
-W pctdefaultprofileportspanelInstallWizardBean.
SIB_MQ_ENDPOINT_SECURE_ADDRESS="5598"
-W winservicepanelInstallWizardBean.accountType="localsystem"
-W winservicepanelInstallWizardBean.userName="websphe"
-W winservicepanelInstallWizardBean.password="admin1"
-W winservicepanelInstallWizardBean.startupType="manual"
-W profiletypepanelInstallWizardBean.selection="default"

Now, your responsefile is ready.

Start creating a profile using pctSolaris.bin like this:

goto WAS_HOME/bin/ProfileCreator

$pctSolaris.bin -options "mypath/responsefile.txt" -silent

Thats it.

Now, Where to see the logs of your profile for the verification?

goto WAS_HOME/logs/wasprofile

This is the place to check for the creation and deletion logs for your profile. The logs will be created like this wasprofile_create_YOURPROFILENAME.log and wasprofile_delete_YOURPROFILENAME.log. If in creation is not successful, that pctSolaris command will throw errors into the wasprofile_create_YOURPOFILENAME.log

Assume that we have created a profile called "Gongura"

What to do next? You need to verify the installation. How to do that? as I said earlier, you need to goto the WAS_HOME/profiles/Gongura/bin. From now on, WAS_HOME/profiles/Gongura is our PROFILE_HOME. We need to check for the installation verification by calling the command

ivt.sh server1 profilename

After this is successfully returns the profile creation information, its the time to start the server. Before that check the status of the server. The ivt.sh starts the server. To know the status of the server,

goto PROFILE_HOME/bin

serverStatus.sh server1

If the server is up, it returns

The Application server appears to be started

otherwise

stopped
