I have two Queue managers. Say QM1 and QM2, and lest say I am sending messages to a local Queue on QM2. Now if my local queue on QM2 is full then provided that I have not selected the Discard Message option my messages should be transferred to dead letter Queue of QM2. But considering a situation where my dead letter Queue for QM2 itself reaches its capacity, where do any new messages to be put to dead queue go???
Is it required in this case that I keep on polling my dead letter queue and in case of it reaching capapcity, I take action so that teh messages don't get discarded???
Please Help!!!  |

---Look in the manuals, somewhere deep down the answer lies.
If the DLQ is full, then the messages are discarded if they were NPM. If they were Persistent, they are put back onto the xmitq at the sending end and the channel comes down.
Assuming that you are talking on the same lines.
"Is it required in this case that I keep on polling my dead letter queue and in case of it reaching capapcity, I take action so that teh messages don't get discarded??? "
---Upto you. And you need to do what your design requirement says. You could as well make it a huge number so that you dont have to do the polling stuff.
But again, if you have so many messages in the DLQ, you should first try and find out why they are landing up there and fix it rather than fixing the dlq. Fix the source of the problem and not the problem itself.

| Try taking a look at the runmqdlq command. It is a dead-letter queue handler that takes a rules file for input to determine how to process the messages. |
