Back-level queue managers

 

When a report is generated by a queue manager that supports segmentation, but is received on a queue manager that does not support segmentation, the MQMDE structure (which identifies the Offset and OriginalLength represented by the report) is always included in the report data, in addition to zero, 100 bytes, or all of the original data in the message.

However, if a segment of a message passes through a queue manager that does not support segmentation, if a report is generated there, the MQMDE structure in the original message is treated purely as data. It is not therefore included in the report data if zero bytes of the original data have been requested. Without the MQMDE, the report message might not be useful.

Request at least 100 bytes of data in reports if there is a possibility that the message might travel through a back-level queue manager.
