So I've always been under the impression that one should issue the endmqm command with the -w parameter to wait for the queue manager to completely quiesce. I thought you would only resort to the -i and -p parameters if that failed. Now I've noticed that all of our unix queue managers have a script that is called during the rc shutdown sequence that issue a "endmqm -i" command. I was going to recommend changing it to the -w parameter, but then I thought, since this script is only being called when the actual machine is being shut down, and we have had problems where -w simply hangs forever forcing us to try another paramter (which in this case would stop the machine from shutting down, possibly while nobody is watching), maybe -i isn't such a bad idea? Any thoughts?

The -i should work as long as the applications using the queue manager(s) don't care that their incomplete units of work may get rolled back the next time these queue manager(s) are started.
I would guess since the machine is going down that there are other more serious issues to worry about than some MQ transactions getting rolled back  |

| Additionally, it is excellent practice to add the MQ_FAIL_IF_QUEICING (sp) option to each MQ API call. This results in an error condition being reported back to the application if the request to cleanly end the queue manager has been submitted. This is the way to programatically cause applications to cleanly terminate if they are currently connected to the queue manager. |

Hi,
How do we know what applications are connected to the QMGR. If I grep on amqzlaa0 it is showing instances, but I want to know who are connected to the QMGR.
Thanks in Advance,
Chandra. |

You can only get this information if you are using MQ v5.3. Otherwise you can only get the number of applications connected by looking at the IPPROCs and OPPROCs of each queue.
