Move messages from one IBM MQ Queue to a different MQ Queue based on the expiry(time to live)

Question

I have a application where I am using IBM MQ in a Pseudo-Synchronous way. I have request Q and Response Q. This will called through service. Now there is a time out period for my service to show the response. But the actual response can be pushed to the response Q after the timeout also. Now I want to move such all delayed messages(timed out) to a separate message Q, such that they can be consumed by a different process.

Is this is possible through setting by time to live? Is any approach available in IBM MQ for such movement. Please refer below image for the scenario.

Answer 1

Don't use time to live because the message will expire and be deleted - unless that is what you want. From your description/picture, it sounds like you want another application to process late responses.

There is nothing in MQ that will move messages older then "x" seconds/minutes to another queue. You will need to write a program to do that. If you write a program, make sure you do the move under a unit of work.

There are several commercial programs that can do it: (1) GUI program: MQ Visual Edit and (2) Command Line (shell): MQ Batch Toolkit .
