I've trawled through the MQ documentation and whilst I can make a stab at the answer, I'd just like a sanity check.
When a report message is created (I'm only thinking of Exception and Expiration) does it have an infinite lifetime? Also, is it persistent, or based on the persistence of the message that caused the report to be created, or the default persistence of the queue it is being placed on? Also for Exceptions, if the original message is move to the DLQ, what happens to it's expiry and persistence?
As an aside (and I REALLY want to get this off my chest) why are reports sent to the ReplyToQueue. Why is there no concept of administration queues as in MSMQ? Has anyone ever got a sensible reply from IBM? Surely I'm not the only one who thinks that they could have put this in by now. <.. rant over ..>
Cheers,
Chris |

| The Application Programming Guide has a section on the Report field of the MQMD. At the end of it, there is a table that gives details on what the MQMD fields are set to on a report message. Expiry is listed as MQEI_UNLIMITED. |

Thanks for the reply. I've got the Information Centre up and still can't find the section you mentioned though. Could you do me a favour and tell me where in the Contents tree it is? Any ideas on the persistence?
Thanks again,
Chris |

| Is it Appendix E of the Application Programmers Reference you need? |

Try chapter 9 of the Application Programming Reference (version with 5.2).

Contents of the message descriptor for a report message: When the queue manager or message channel agent (MCA) generates a report message, it sets the fields in the message descriptor to the following values, and then puts the message in the normal way:
Field in MQMD
Value used
StrucId
MQMD_STRUC_ID
Version
MQMD_VERSION_2
Report
MQRO_NONE
MsgType
MQMT_REPORT
Expiry
MQEI_UNLIMITED
Feedback
As appropriate for the nature of the report (MQFB_COA, MQFB_COD, MQFB_EXPIRATION, or an MQRC_* value)
Encoding
