Hello All,
I am getting below errors while starting the queue manager.
My Queue Manager are started but CLUSSDR/CLUSRCVR Channels are not working...
/var/mqm/qmgrs/errros/AMQERR01.LOG
AMQ7467: The oldest log file required to start queue manager QMMPCS is
S0000001.LOG.
EXPLANATION:
The log file S0000001.LOG contains the oldest log record required to restart the queue manager. Log records older than this may be required for media recovery.
ACTION:
You can move log files older than S0000001.LOG to an archive medium to release space in the log directory. If you move any of the log files required to recreate objects from their media images, you will have to restore them to recreate the objects. An older log file is one with a numerically smaller log
number (but allowing for log number wrapping at 9999999).
-------------------------------------------------------------------------------
02/15/11 22:55:55 - Process(544770.7) User(esbadmin) Program(amqzmuc0)
Host(DSRSBS)
AMQ7468: The oldest log file required to perform media recovery of queue
manager QMMPCS is S0000000.LOG.
EXPLANATION:
The log file S0000000.LOG contains the oldest log record required to recreate
any of the objects from their media images. Any log files prior to this will
not be accessed by media recovery operations.
ACTION:
Use this information together with the information in the most recent AMQ7467
message. Archivable log files are all those older than BOTH S0000000.LOG and
the log file mentioned in the AMQ7467 message.
Below are LOG available in /MQHA/QMMPCS/log/QMMPCS/active
-rw-rw---- 1 mqm mqm 16785408 Feb 15 19:36 S0000003.LOG
-rw-rw---- 1 mqm mqm 16785408 Feb 15 19:36 S0000002.LOG
-rw-rw---- 1 mqm mqm 16785408 Feb 15 22:55 S0000001.LOG
-rw-rw---- 1 mqm mqm 16785408 Feb 15 23:12 S0000001.LOG
I already move the old logs in /tmp file systems which are not presently.
Can anyone please provide input to resolve this issue as our cluster is down due to this problem.
Thanks,
Sonalika |

It's not down because of this - that's the perfectly normal informatory message from a queue manager using linear logs.
I'd be more worried about the fact you seem to have 2 log files S00000001.LOG, no S00000000.LOG, you're moving log files backwards and forwards to /tmp without any apparent understanding of linear logging and the queue manager isn't running as mqm even though that's who owns the log files in the file system.
But none of this would directly stop the channels working, provided the queue manager actually did come up.

I also infer the following (since you've not mentioned this):
- the queue manager is supported by a high-availability software system
- the logs are mounted on shared disck
- it's been failed over at least once recently
- you didn't follow the advice given here during the set up
Tell me if I'm right, and why you're trying to start this queue manager. Or perhaps more relevant, why it was stopped.

Hi Vitor,
Thanks for your quick response.
MQ 7.0 is installed in AIX 6.1 machine.
MQ running under HACMP
node 1- /MQHA/QMMPCS/log/ and /MQHA/QMMCMS/log
node 2- /MQHA/QMMPCS/log/ and /MQHA/QMMCMS/log
Today afternoon, MQ-HA resource group has moved from node2 to node1 (presently available on node1) .
esbadmin - user belongs to mqm group and having all mq permissions.
Today afternoon once MQ resources moved into node1 below errors has occurs and cluster receiver channel goes down.
I google the AMQ7468 and AMQ74687 error information and according to that I moved the old logs into /tmp file system..
dis chstatus(*)
1 : dis chstatus(*)
AMQ8417: Display Channel Status details.
CHANNEL(TO.BHIM.QMMCMS) CHLTYPE(CLUSSDR)
CONNAME(10.67.110.121(5121)) CURRENT
RQMNAME(QMMCMS) STATUS(RUNNING)
SUBSTATE(MQGET) XMITQ(SYSTEM.CLUSTER.TRANSMIT.QUEUE)
Cluster Receiver is not display here.
I manually tryting to start Cluster Receiver channel
START CHANNEL(TO.BHIM.QMMPCS)
5 : START CHANNEL(TO.BHIM.QMMPCS)
AMQ8018: Start WebSphere MQ channel accepted.
Is anything goes wrong direction? why suddently qmgr receiver channels are not working..
Moving the resource group to orginal state will solve the problem?
Thanks,
Sonalika |

You cannot start the receiver that way. It will automatically start when the sender on the other end starts.
On UNIX, never run the QMGR as any ID other then the mqm ID. Every ID in the mqm group should have the mqm group as their primary group.
You ask why? Because when IDs create objects, those objects get rights granted to the primary group implicitly.
imho only mqm should be in the mqm group and only the WMB broker service ID is an exception because they are knot headed. |

This doesn't alter the fact that mqm is a specific user to the software & you need a fairly good reason not to use it to run the software. What is your good reason?

Those errors do not have anything to do with channels and are indicative of a normally running queue manager.

Google doesn't offer ratings - what site did you find that advised you do do that? It's a very odd thing to do especially for those messages (which don't require action and which your examples are warning against). Post the link & explain why you felt the advice was relevant to your situation.

The status is RUNNING - what's the problem??

And?

What's not working? How do you know the receiver channels are down? What symptoms are you seeing?
Most importantly, where are the error messages from the failing channels?
| sonalika wrote: |

What problem? The only problem here seems to be you're moving randomly moving log files and still havn't answered my question about your HACMP set up. How have you configured the shared storage?
And no, moving the resource group around in the hope the magic will come back is as likely to help as moving the files to /tmp. Don't randomly do things; investigate the problem and formulate a solution.

And the queue manager error logs say what? The general WMQ error logs say what? The FDC files (if any) say what?

Nice one Centurion. And sonalika I do hope that the particular /tmp directory to which the files were moved is available to both nodes? Should you need them  ...
