explains that you don’t need Remote Queue Defs inside a cluster when sending messages between QMs inside the cluster. If you want to put a layer of abstraction between the putting app and the clustered queue you can use a locally defined Alias queue. Basic MQ 101.
What I would like to know is are remote queue definitions inside a cluster, that point at local queues defined on other QMs in the cluster, regardless if those local queues are clustered or not, expressly forbidden or allowed.
Here is the scenario:
QM1 and QM2 are not in a cluster. They use regular SNDR/RCVR channels.
Apps connected to QM1 send to QM2 via Remote Q Defs defined on QM1 that aim at QM2.
QM3 and QM4 are in a cluster.
QM1 is then added to that cluster.
QM1 still talks to QM2 the way it always did.
I want to know if I can repoint the existing Remote Q on QM1 (that currently aims at LOCAL.QUEUE.OLD queue on QM2), to LOCAL.QUEUE.NEW on QM3 and QM4.
If yes, what would I put in Remote QM Name of the Remote Q Def? Leave it blank?
If yes, what would I put in the XMITQ parm of the Remote Q Def, SYSTEM.CLUSTER.TRANSMISSION.QUEUE? Or leave it blank?
I know I could delete the Remote queue on QM1 and replace it with a Q Alias on QM1 by the same name, with a TARGQ of LOCAL.QUEUE.NEW. But I’m wondering if its possible to avoid replacing those remote queue defs on QM1 in favor of just altering the remote queue defs?
If anyone has a link to IBM doc that specifically allows are prohibits remote q defs in a cluster from pointing to other local, optionally clustered, queues in a cluster please share that link.

I would leave both the RQMNAME and the XMITQ blank.
There's no reason it shouldn't work.
There's no specific reason I can think that specifying S.C.T.Q in the XMITQ would cause a problem, either, but it feels safer to not do so. |

Hi Peter,
Please only fill in the remote qname (clustered queue name) and leave all other fields blank e.g.
def qr(my.clustered.queue.b) rname(queue.b)
If there is a connection or name resolution problem the message should land on the local DLQ.
Have fun
