When a valid persistent message can not be delivered to Remote (Target) queue due to Remote queue is full (rc=MQRC_Q_FULL),
Will this persistent msg stay in XMIT queue(or Log) for later processing or goes into DLQ ?
Thanks.

According to the Intercommunications manual,
| Quote: |
When this occurs in a staging or destination node, there are three ways that the
MCA copes with the situation:
1. By calling the message-retry exit, if one is defined.
2. By directing all overflow messages to a dead-letter queue (DLQ), returning an exception report to applications that requested these reports.
Note: In distributed-queuing management, if the message is too big for the DLQ, the DLQ is full, or the DLQ is not available, the channel stops and the message remains on the transmission queue. Ensure your DLQ is defined, available, and sized for the largest messages you handle.
3. By closing down the channel, if neither of the previous options succeeded.
4. By returning the undelivered messages back to the sending end and returning a full report to the reply-to queue (MQRC_EXCEPTION_WITH_FULL_DATA and
MQRO_DISCARD_MSG). |
You're going to probably fall into #2 and have your message put on the DLQ. Not sure why the manual states three ways and then lists four. |
