Re: QMgr leaving Cluster

[Lynn Nelson]

Michael,

 

We often use MQSC on the local QMgr and can see the cluster information.  Anyway, all of our tools show the QMgr is no longer in the cluster, no matter which system we run them from.  It is almost as if the repository is not retaining the information about the new QMgr.

 

    Thanks,

    Lynn

Lynn,

run that same command from any other Qmgr in the Cluster...

 

as far as I remember a Qmgr will never see itself as a Cluster QMGR via MQSC,

you should do a DIS CLUSQMGR(NYKYCPR4) ALL on any QMGR in the cluster other then NYKYCPR4 itself.

Peter,

 

Here is Jim's response: "If you perform DISPLAY CLUSQMGR(qmgr name) ALL it will show you all the WMQ cluster information about a specific queue manager.  In this case it appears that something has removed the information in the Cluster parameter which tells the queue manager that it is part of a cluster, even though all the channels and shared queue information still remain."

 

Here is the output:

 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

5724-B41 (C) Copyright IBM Corp. 1994, 2002.  ALL RIGHTS RESERVED.
Starting MQSC for queue manager NYKYCPR4.

 

     1 : DISPLAY CLUSQMGR(NYKYCPR4) ALL
AMQ8147: WebSphere MQ object NYKYCPR4 not found.
     2 : END
One MQSC command read.
No commands have a syntax error.
One valid MQSC command could not be processed.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

The cluster channels are still visible in MQSeries Explorer, when displaying the channels using the command line and from other WMQ gui tools.

 

    Thanks,

"  You come back later and do a DISPLAY CLUSQMGR command for the queue manager and none is found."

"  The cluster sender and receiver channel's are still there and even the queues are still shared (or so they show).  "

 

The member of your team is contradicting himself. The DISPLAY CLUSQMGR command displays info about the cluster channels. What does it show? Can you post the output of the command? And also the output of the command that makes you say your second sentence above.

Another member of my team is working on this and this is what he said:

 

"Basically we added the Cluster sender and receiver channel's to make an existing queue manager part of a cluster and then shared queue's in the new queue manager to the cluster.  Everything is working well.  You come back later and do a DISPLAY CLUSQMGR command for the queue manager and none is found.  The cluster sender and receiver channel's are still there and even the queues are still shared (or so they show).  If you display the cluster on MQ Explorer the queue manager does not display as part of the cluster."

 

This has happened several times.  The problematic QMgr is at a higher CSD level than the others (including the repository), so we are updating them all to the same CSD level to see if this fixes it. 

 

In the meantime, I was wondering if anyone else had seen this strange behavior and had any suggestions as to the cause?

 

    Thanks,

    Lynn

"somehow is removed from the cluster"

 

What makes you think that?

Hello,

 

Has anyone ever seen this?  We have a cluster that had been working fine until we recently added a new fourth QMgr.    Everything is processing properly and suddenly this new QMgr decides it wants no part of the Cluster and somehow is removed from the cluster.

 

    Thanks,

    Lynn
