Hi all
I am not able to stop Queue manager using endmqm command. The command is executed but it gives me this message
"Quiesce request accepted. The queue manager will stop when all outstanding work is complete "
but it does not stop the Queue manager. when i use dspmq command, it gives me following status
QMNAME(test1) STATUS(Quiescing) |

are there any applications / utilities active that do not honor the queuemanager shutdown request? if they stay active, and you shut down the qmgr mode quiesce, the queuemanager will not end unless those applications disconnect.
in addition, there are options of the endmqm command that help you in this situation. check the administration manual for those options.

| Unless applications issue the FAIL_IF_QUIESCING option on their MQI calls - they are not notified of the queue manager quiesce condition. |

which basically means that the QM will continue to take on new units of work i believe and therefore not shutdown.
if this is an urgent matter and you need it shutdown for a reason then i would add the -i flag to your endmqm
this will shut down the QM straightaway even if it is quiescing however, you run the risk of losing data that is being processed at that time if it is not persisent.

Ending / restarting the qmgr will discard ALL its non-persistent messages except any that were successfully added to a queue with attribute NPMCLASS(HIGH). |

What data would be lost with endmqm -i that would not be lost with just endmqm?

Well no - you said by ending the qmgr you run the risk of losing NP messages being processed at that time. In fact you lose all NP messages. It's not so much a risk as a certainty.
Ah yes, except for any NP messages are on queues with NPMCLASS(HIGH). In that case they are not automatically discarded. |

NPMCLASS(HIGH) - This setting enables nonpersistent messages on this queue to be retained across a queue manager restart. Nonpersistent messages may still be lost in the event of a failure.

I stand corrected apologies.
