I am practicing Multi hopping. The scenario is mentioned below
QMA->QMB->QMC
I am successful in sending messages from QMA to QMC.
An application opens a remote queue on QMA and place message in QMC and expects reply in queue 'REPLY' in QMA.
I created a local queue 'REPLY' in QMA.
What are the objects that i should create in QMC and QMB such that i get reply messages in 'REPLY' queue in QMA?
i studied intercommunication manual but this scenario is not explained.
Please provide your valuable suggestions |

If you are using a request reply model then looking at the ReplyToQ and ReplyToQMGR fields in the MQMD when the message gets to QMC should give you an idea.
IF (for example) the ReplyToQMGR says 'QMA' then you have to provide a Queue Manager Alias on QMC called QMA. This would point to QMB where there is similar alias for QMA that points to the right QMGR
IF you are not using a request reply model then just doing what you did to get from QMA to QMC in reverse should do it.
I hope you have DLQ's defined on your QMGRS. This will help you find things that can't be delivered.
Just an idea. Someone else will probably be along with another one shortly.

What have you tried? What were the results?
Distributed queuing requires a QRemote definition on QMA, transmission queues, and sender-receiver channels between QMA-QMB, and QMB-QMC, so that the request message to flow from QMA->QMB->QMC. For the reply message to flow back to QMA, you will need a transmission queue, sender-receiver channels between each qmgr QMC->QMB->QMA.
No queue-manager aliases are needed.

... if you provide a DEFAULT path for the messages to flow. Otherwise you do need qmgr aliases to route the messages, or ReplyTo queue aliases (qr)

And there are security risks in using DEFAULT paths.
