I am testing a newly built Cluster with Qmgr QM1 active on Node A and QM2 active on NodeB . QM1 and QM2 are FR
After migrating all the queue objects from existing MQ (6.0) to MQ V7, I am unable to get load balancing working from QM1. When I put messages to the TEST.IN queue using amqsput, all messages goes to local defined queue. However, it works fine from QM2.
dis QC(TEST.IN)
2 : dis QC(TEST.IN)
AMQ8409: Display Queue details.

Any thoughts on what could be the issue. ? |

what happens if you switch the clusqt attribute from qlocal to any?
I would expect that cluster work load rank and cluster work load priority attributes are the same for all the instances of the queue involved.

CLUSQT is set to QLOCAL. I believe you mean CLWLUSEQ property. This is set to ANY for both the instances of this queue.
Also, to clarify the issue, when I put messages from NodeA , all messages go to the local queue defined on Node B . No messages are going to the local instance of the queue on Node A.
However when doing a amqsput from Node B to this queue , messages are split 50-50 to both the queues.

Anything reported in queue manager logs reference differences in attributes between the clustered queues?

I had to delete the cluster queue from both the nodes and recreate the queue .
Now, I can get the balancing. |
