Vote if you think it's a good idea. Here's the direct link to cast your vote:

* QM1, QM2, QM3, QM4, QM5 are all in the same MQ cluster.
* QM1 hosts the sending apps.
* QueueA is clustered on QM2, QM3, QM4, QM5.
* App A puts to QM1, and the load is distributed evenly to QueueA on QM2, QM3, QM4 and QM5, roughly 25% each.
* QueueB is added to QM2 and QM3 only. It is not added to QM4 or QM5.
* App B starts putting to QM1. "B" messages are load balanced between QM2 and QM3, roughly 50% each.
* But now "A" messages find themselves routing primarily to QM4 and QM5 only, because "B" messages are using the channels to QM2 and QM3 only and influencing the routing that QM1 is doing.
The routing of App A's messages are being influenced by App B's messages and this is a bad thing.
* If implemented this RFE would allow the MQ Admin to tell QM1 to load balance at the queue level, and this would restore App A's load balancing back to 25%/25%/25%/25%, regardless of what App B, C, D...App Z are doing.
