I have a requirement to duplicate MQ messages(including message ID) on to another queue. This is needed for investigating an intermittent prod issue related to message format /content, but we cannot afford to pause the listener to capture the messages.
I understand PUB/SUB can't be served for this purpose. Any other options to duplicate the messages(including message ID). Please advise |

This question have been asked a number of times here.
There are answers if you care to look for them. I'd look for an 'exit' to do the job however getting it right really needs a good deal of MQ and C programming expertise.
Why the requirement for retaining the MQMD.ID? are you crafiting it yourself?
It is not a good idea to have duplicate (best practice and all that) ID's on the same Queue Manager.
If you aren't crafting it in code then the PUB/SUB via an alias queue is probably the simplest and quickest way to do this.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

You can code a simple message splitter (one MQGET, two MQPUTs).
Using WMB/IIB this would take about 30 seconds to code.
Or you can use this ready-to-use example with source
