Hi All,
When I see the system defined queues and its status, process is associated with them. (not for all system defined queues.)
Process AMQZDMAA is there when I check the status of the queue SYSTEM.PENDING.DATA.QUEUE
[ AMQZDMAA - Deferred message handler ]
is mentioned in the IBM reference links.
Could some one please tell me in detail what is the functionality of the Process AMQZDMMA? And How it works internally ? Why its critical ?
Thanks in advance.

Part of the logging I think. Why do you need detail?

This is the intelectual property of IBM, and should not be discussed.

All the internal queue manager processes are critical. Bad things will happen if you interfer with them.
Why the question? Aside from morbid curiosity?

| It is an internal process that does internal things. It has no public interfaces. Certain operations will not succeed if the task is not there. |

I think for logging : processes are...
AMQHASMN.EXE The logger
AMQHARMN.EXE Log formatter (LINEAR logs only)
AMQZLLP0.EXE Checkpoint process
I know the Processes are the properties of IBM.
I don't find details about this process that's why being curious I asked the question.
I am not going to do anything with these processes but wanted to know about them, I case if I'll get some problem then in advance I should be aware about the process and its functionality and its criticality.

I know, all the queue manager process are 'internal' and do 'some' internal things.
I am curious about, 'some' is what ?
(at least for the above mentioned process)

If you get a problem with any internal processes, then the response is to restart the queue manager (if it hasn't ended abnormally). If it doesn't stop, there's a documented manual stop procedure.
Knowing what an individual process is doing and how adds nothing to this, as there's no other resolution possible. If this fails to help, it's PMR time.

I applaud your curiousity.
Much of the internals are not documented as to what or exactly how something is done.
I suppose you could start a trace...

How to do that on the 'internal' processes?
