Is there a problem with the IBM MQ queues?
Use this topic for investigating potential problems with IBM MQ queues.
If you suspect that there is a problem affecting the queues on your subsystem, use the operations and control panels to display the system-command input queue.
- If the system responds
- If the system responds, then at least one queue is working. In this case, follow the procedure in Are some of our queues working?.
- If the system does not respond
-
The problem might be with the whole subsystem. In this instance, try stopping and restarting the queue manager, responding to any error messages that are produced.
Check for any messages on the console needing action. Resolve any that might affect IBM MQ, such as a request to mount a tape for an archive log. See if other subsystems or CICS regions are affected.
Use the DISPLAY QMGR COMMANDQ command to identify the name of the system command input queue.
- If the problem still occurs after restart
- Contact the IBM support center for help (see Contacting IBM Software Support ).
- Are some of our queues working?
Use this topic to investigate when problems occur with a subset of our queues. - Are the correct queues defined?
IBM MQ requires certain predefined queues. Problems can occur if these queues are not defined correctly. - Does the problem affect only remote or cluster queues?
Use this topic for further investigation if the problem only occurs on remote or cluster queues. - Does the problem affect only shared queues?
Use this topic to investigate possible queue sharing group issues which can cause problems for shared queues.
