Hello,
I need to make all messages hitting DLQ 'persistent', and then investigate the messages.
One way of doing would be to move the messages to another queue making the messages persistent, and then putting them back to DLQ so that the DLQH can do its job.
Is this feasible ? does any one have the code for this ready ?
any help would be appreciated.
thanks, |

If you're putting the messages to a second queue, why not just have the DLQ handler process that second queue? I think thats cleaner that trying to put the message back to the original DLQ.

And if you're going to the trouble to move the messages in the first place, you might as well put in a small bit of filtering logic to put important messages in one queue, and less important messages in another.

and if you're going to tell us about your environment we could maybe answer the question about a existing tool to perform this kind of message-move-and-persistence-change.

The "q" program (ma01) should do it:
| Code: |
q -ap -I SYSTEM.DEAD.LETTER.QUEUE -o MY.DLQ

Do you really need to change the persistence of the messages? By specifying non-persistent messages, the application architect has accepted that under certain circumstances WMQ will throw the data away. If you make the messages persistent then they will certainly survive a queue manager restart, but if you need to reinput them to the application then presumably you will have to reinstate the original persistence. Are you sure this is what you want?
Just a thought ...
Cheers -

hi cliff,
Yes that is exactly what i need to to.
hi wschutz,
thanks. i think thats what i need.
to sum up, i need to write a script that runs the Q program, once a message hits the DLQ. Then i run the DLQH to process 'my.dlq'.
Am i missing anything here,
thanks,

You could use triggering on the DLQ.
