I have 2 Queue Manager (QM1 & QM2) in a cluster (MYCLUSTER). Both have full repository of MYCLUSTER. On QM1 I have a queue called Q1 and on QM2 I have a queue called Q2. I can put messages to Q2 from QM1 but I can not put messages on Q1 from QM2. Any ideas?? When I displayed the queues in the cluster, on QM1 I can see both queues (Q1 & Q2) while on QM2 I can only see Q2. I tried to refresh my cluster but I am still having the same problem.

First question (check the obvious): While you made the queue managers in a cluster (MYCLUSTER) when you created each queue (Q1, Q2) did you make them members of the cluster too? i.e., DEFINE QL(Q1) CLUSTER(MYCLUSTER)
Otherwise they operate like normal local queues....

Yes, I did make them part of the cluster MYCLUSTER. I created Q1 on QM1 first. After doing this I can see that it is a part of MYCLUSTER by displaying the cluster queues. I then created Q2 on QM2, but after displaying the cluster queues, I can see Q1 & Q2 on QM2 and only Q1 on QM1. Can this be a bug on MQSeries V5.2 on the AS/400? It's like after creating the first queue (Q1) it took that as the master repository and won't send any changes/addition to the repository from any other Queue Manager in the cluster.

-Have you tried issuing the DIS CLUSQMGR command? This shows all the queue managers in the cluster (rather than queues in the cluster). This command will:
Use the DISPLAY CLUSQMGR command to display cluster information about queue managers in a cluster. If you issue this command from a queue manager with a full repository, the information returned pertains to every queue manager in the cluster. If you issue this command from a queue manager that does not have a full repository, the information returned pertains only to the queue managers in which you have an interest. That is, every queue manager to which you have tried to send a message and every queue manager that holds a full repository.
So this command should show both QM1 and QM2 regardless of which machine you issue it on. If you don't see both, that means the repositories aren't talking to each other properly.
Can this be a bug on MQSeries V5.2 on the AS/400?
-Probably not, quite a few people are using clustering with AS/400
It's like after creating the first queue (Q1) it took that as the master repository and won't send any changes/addition to the repository from any other Queue Manager in the cluster
-If there was any inconsistency between the queue managers regarding which objects are in the cluster, a REFRESH CLUSTER(clustername) command issued on the queue manager which appears to be out of sync (in this case QM1) should cause it to renegotiate all the cluster objects with the other full repository (QM2). If this still doesn't solve the problem, then this means that cluster information is not going from QM2 to QM1 (but appears to be working from QM1 to QM2). This probably means an issue with the CLUSSDR channel on QM2, or the CLUSRCVR channel on QM1. Check the SYSTEM.CLUSTER.TRANSMIT.QUEUE on each machine to see if the depth is greater than 0.

| Thanks for the recommendations. I was able to get my environment working again after recreating the channels. I guess some how they were corrupted by removing them out of the cluster and adding them back. |
