Then kick start to install

rpm -ivh MQSeriesServer, runtimes yata yata yata



1. create a default q manager
call it MQ.QM1
[mqm@localhost ~]$ crtmqm MQ.QM1
There are 90 days left in the trial period for this copy of WebSphere MQ.
WebSphere MQ queue manager created.

2. Start Q Manager

[mqm@localhost ~]$ strmqm MQ.QM1

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:
Name=MQ.QM1
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 *#
#* is stored *#
#***********************************************************************#

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

QueueManager:
Name=pluto.queue.manager
Prefix=/var/mqm
Directory=pluto!queue!manager

DefaultQueueManager:
Name=saturn.queue.manager

ApiExitTemplate:
Name=OurPayrollQueueAuditor

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 6450 6436 0 12:22 ? 00:00:00 /opt/mqm/bin/runmqchi -m MQ.QM1 -r
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
:):)
[mqm@localhost mqm]$ runmqsc
5724-H72 (C) Copyright IBM Corp. 1994, 2005. ALL RIGHTS RESERVED.
