Hi All,
I'm running Websphere MQ 7.5 on suse linux. I have a problem with PUB\SUB (that i do not even use). FDC's are created for all qmanagers:
Probe Id :- KN467002 |
| Application Name :- MQM |
| Component :- kqiReconcileDurableSubscribers |
| SCCS Info :- /build/p000_P/src/lib/lqm/amqkdspa.c, |
| Line Number :- 1012 |
| Build Date :- Jun 4 2012 |
| Build Level :- p000-L120604 |
| Build Type :- IKAP - (Production) |
| Effective UserID :- 1000 (mqm) |
| Real UserID :- 1000 (mqm) |
| Program Name :- amqzmuc0 |
| Addressing mode :- 64-bit |
| LANG :- POSIX |
| Process :- 27316 |
| Process(Thread) :- 27345 |
| Thread :- 1739 |
| ThreadingModel :- PosixThreads |
| QueueManager :- QMT24HSE |
| UserApp :- FALSE |
| ConnId(1) IPCC :- 23515007 |
| ConnId(2) QM :- 407690 |
| Last HQC :- 2.5.5-19431888 |
| Last HSHMEMB :- 2.6.6-278736 |
| Major Errorcode :- MQRC_OBJECT_DAMAGED |
| Minor Errorcode :- OK |
| Probe Type :- INCORROUT |
| Probe Severity :- 4 |
| Probe Description :- AMQ6125: An internal WebSphere MQ error has occurred. |
| FDCSequenceNumber :- 5155

and in qmanagers error file i have:
AMQ5052: The queue manager task 'QPUBSUB-CTRLR' has started.

EXPLANATION:
The publish/subscribe utility task manager has started the QPUBSUB-CTRLR task.
This task has now started 107668 times.
ACTION:

It seems that some system queue is damaged , and i have tried strmqm -c but it ends with error (one object cannot be repaired). This logs are growing and they will fill in disk space.
Any idea?

If you are not using it, delete the damaged object, stop the qmgr and run strmqm -c again to recreate it.

But where can I find which system queues are damaged? I suspect queue's for PUB/SUB are damaged since i have error from this service for all qmanagers on this server.

I'd look in the error logs to see if the name of the damaged object is provided. I'd suggest that you open a PMR with IBM - ask IBM how to identify the offending object.

If you are able to connect to the queue managers using MQ Explorer that will also help identify the queue(s)...

That FDC implies a problem opening SYSTEM.DURABLE.SUBSCRIBER.QUEUE.
If you're using linear logging then it should be possible to recreate the queue.
If you're using circular logging, but are NOT using pubsub, or durable subscriptions, then you could safely delete and recreate the queue.

If you're unaware of any administrative error leading to this queue becoming damaged you should open a PMR for this problem, regardless of whether either of the above actions is open to you.

.

That is the one (damaged queue). I have list all system queues wit DISPLAY QLOCAL(*) and then I have try to display every one of this queues by name DISPLAY QLOCAL(SYSTEM.DURABLE.SUBSCRIBER.QUEUE). Only for this queue i get OBJECT_DAMAGED.
I will delete this queue, recreate it and hopefully solve this problem.
Thanks a lot to all of you who tried to help me,
Marko

There's a little icon at the top-right of the queue content window that displays/suppresses SYSTEM objects from the view. If you hover over it with your mouse, it says something like 'show/hide system objects.'
