We are using MQ clustering in our applications. One of our applications cannot put messages in a clustered environment as it has to maintain message affinity. I'm not able to use the bind option here as the developer opens & closes the queue for each and every put (I’m trying to change this, but I'm unable to push this change as this is a packaged software we bought)
Right now, though I've the queue in 2 queue managers, only one of them is clustered. We have to go through a manual fail over process in case of any issues.
My question is, using workload priority, how do I configure my environment, in such a way that the other queue manager will pick up the load when one goes down using MQ v6 clustering in capabilities. I don’t know how to use the cluster workload priority to make this work.
Can someone help me ... |

As you have message affinity you have some restrictive choices:
cluster priority on the queue 9/0 so you would only get a message on the queue with cluster priority 0 if the queue with clusterpriority 9 is not available.
Note cluster priority may not be the right term... Check in the new cluster attributes...
The other possibility would be for you to use a channel table.
Enjoy

I have a similar setup with a cluster queue being on two servers. On one of the two servers I have set cluster workload priority for the queue to 9 and on the other server it is set to 0. Yet the messages are being routed to both the servers.
Is there any other step required after we change queue definition? Or Do we need to set priority in queues or on channels?
Regards
