Convincing people that is isn't an MQ problem!
Most of our 'problems' come with channels and are usually caused by something other than MQ (Network burp, firewall reboot, etc)
In terms of MQ problems most of ours seem to be because developers are still trying to use MQ synchronously and they are really pretty new to MQ Series so they haven't quite grasped the asynsc thang yet.
Other than that MQ here seems to just do what it should do. |

In all honesty, most of the problems that I have dealt with that are initially identified as "MQ Problems" end up being problems with the Applications or Network.
First thing to do when you get a call that claims there is an "MQ Problem" is log on to the MQServer in question and check the health of the MQManager (The following assumes that the individual reporting the "MQ Problem" is as clueless as they usually are and can not give you any specific information about what there problem is.):
# dspmq
QMNAME(QMGR01) STATUS(Running)
Then:
# runmqsc QMGR01
end
Just to make sure the MQManager is responding. Sometimes dspmq will show the MQManager status as running but for some reason or another it will not respond to MQSC commands.
Then check /var/mqm/errors or the Platform equivalent for newly created .FDC files and /var/mqm/qmgrs/MQMGR/errors/AMQERR01.LOG for errors.
If there are new .FDC files it still may not be a problem with MQSeries as such. That is to say MQSeries may have been impacted but still isn't necessarily the root cause of the problem.
Check your DLQ Depth.
Then check to see if your vital processes like the Trigger Monitor, Listener and Channel initiator are running.
Check for application Queue's that are filling up.
Generally speaking if you set everthing up correctly MQSeries is very stable.

Another interview?

mqkid, what are you going to do if the person that is hiring reads this MQ board and sees your responses are exactly the same?
