Hi,
I use a msgflow to route request messages to queues feeding backend applications. They are all cluster-shared queues visible to the broker qmgr. So no extra remote queues and xmitqs are necessary.
however, although I set the replyToQmgr field empty explicitly before routing the msg to these cluster-shared remote queues, the messages arrive at these cluster-shared queues with replyToQmgr field set to the broker's local qmgr name.
Since back end applications don't connect to the broker qmgr, they fail at putting the reply back to the replyToQ resides on the broker's qmgr, even though the replyToQ is a cluster-shared too, individually visible to their qmgrs. This is all due to the fact that replyToQmgr field is not empty as it should have been.
Can anyone please share some insight on these?
To my understanding, whenever a queue is set to cluser-shared, a remote queue is automatically created on every member qmgrs pointing the the real queue. So this alone should make the name resolution rule to not populate the replyToQmgr field with that of the local qmgr name. Am I right on this?
appreciate any insight.

| No, you are wrong. The ReplyToQMgr field is always filled in with the name of the local qmgr unless it is non-blank, in which case it is left as it is. |

Not quite, however the behavior is very similar to a QR.

So if you want it to be non qmgr specific and shared in the cluster you need to use/set up a cluster alias (Particular form of qmgr alias).
See intercommunications manual  for more details
