May be dumb question:
Can I have a QA on QM1 defined as remote with target queue QB on QM2 where the target queue QB is defined as a remote with target queue QC local on QM3?

QA(R)/QM1/Box1--->QB(R)/QM2/Box2----> QC(L)/QM3/BOX3?

I am looking for this example in MQ documentation I could not get any mention of the above scenario. May be I am missing something?
Could you please let me know where I can get more info on the above setup? ( already checked intercommunication manual). What could be the advantages of the above setup?

Yes. Its possible. You can use such kind of scenarios when MQ is used in Hub and Spoke.

You are sending the messages to Hub by using remote Definition(QA/QM1) and that Hub(QM2) will divert those messages to another remote definition(QC/QM3).

Thanks.

No. Alias queues are alias queues, remote queues are remote queues. No reason you can't have an alias that points at a remote queue.

You're missing the description of mutli-hop, which is what you're describing.

Check again.

Connecting 2 boxes that have no direct connection? Building a hub and spoke?

Other uses are limited only by your imagination.
