Hi all,
We've seen problems when migrating a clustered queue from one queue manager to another. Since the queue was removed _before_ it was taken out of the cluster, the cluster did not store the location of the queue correctly. This resulted in messages on the old queue managers DLQ with a 2085 error.
The solution is to remove the new queue, recreate the old queue, remove it from the cluster, remove the queue and finally recreating the new queue again.
Now for my question, is it possible to view the cluster information on a specific qmgr? I'd like to know what the qmgr thinks about the location of the cluster queue etc.
Can I parse this info from SYSTEM.CLUSTER.REPOSITORY.QUEUE ?
thanks |

In your case you could have done something a little be less intrusive.
After the queue was migrated issue
REFRESH CLUSTER(MYCLUSTER)
on the full repos showing the old info. This should update the FR with the new info.
Issue:
REFRESH CLUSTER(MYCLUSTER) REPOS(YES)
on the partial. This tells the PR to get the information again from the FR which has now the updated info (see above).
As for viewing the full repository is a must.
dis qc(*) clusqmgr should give you an overview
Enjoy

Thanks, I issued the command amqrfdm which gave me a whole bunch of information to say the least. However, I'm not sure about the information since one of the queues suddenly indicated an ascii code that was the same queue manager but in another cluster.
Anyway, MQMON gave me the information I needed in this case as it listed 2 cluster queues - one on each queue manager.
However, being able to see sequence numbers etc on all cluster queue definitions - as with amqrfdm is surely sweet.
There's supposed to be a graphical tool to parse the output file from amqrfdm, does anybody have more info on this?
I'm a little wary against using refresh cluster since last time we did it on a partial repository, it dropped ALL cluster info and (due to a bug?) didn't update properly causing a lot of 2085 errors.
Thanks for the tips on the dis qc command, I somehow missed that extra parameter showing the queue manager. |

Something must be wrong with your setup.
You should have received:
2087 0x00000827 MQRC_UNKNOWN_REMOTE_Q_MGR
or
2189 0x0000088d MQRC_CLUSTER_RESOLUTION_ERROR
Of course you should only do a refresh cluster(mycluster) repos(yes) if you have made sure that the communications between the PR and it's FR are working....
a) channels are running
b) XMITQ holds no messages for the destination (to check for on both FR and PR)
Frequent problem is that some queue in the target fills up and the messages start piling up in the SCTQ (system.cluster.transmit.queue). This is a sign that your cluster is ill and sufferring...and it will slow down operations considerably. Worst case scenario... you'll only get your messages once you have resolved the hold up...
Enjoy
