All,
Suppose if I want to clear System.Dead.Letter.Queue on a Queue Manager, Can I clear this Queue?
If so, how to proceed? If I want to clear any other System related Queues, Can I clear??
Thank you!!

if you are sure that losing these messages is not a problem, go ahead and clear the system dead letter queue.
what other system queue's were you thinking of clearing?

Instead of clearing them you may want to have a look at the runmqdlq command which will give you the option among other things to RETRY, DISGARD the messages on your DLQ.

Thank you all,
Other than Dead Letter Queue, I wanted to clear SYSTEM.AUTH.DATA.QUEUE and SYSTEM.ADMIN.QMGR.EVENT and CHANNEL.EVENT.
I wanted to clear all these System Object Q's because we are rebooting the server and starting a fresh process
and I want to observer all the Queues and events that take place.
Thank you once again to you all!!

I would NOT clear the SYSTEM.AUTH.DATA.QUEUE it holds your authorisations to the qmgr...
clearing the EVENT queues should be ok, if you are not interested...

By default, the SYSTEM.*.EVENT queues are set to non-persistent, and the Event messages written there get the persistence from the Q attribute. So, rebooting the server will remove those messages anyway.
Cheers,

If you are truly starting fresh and want to observe, then I'd suggest that you delete your queue manager and recreate it. This will guarantee that it is created fresh. |
