Variations in the MQGetMessageOptions fields

Some queue managers do not support the Version 2 MQGMO structure, so you must set some fields to their default values.

When using a queue manager that does not support the Version 2 MQGMO structure, leave the following fields set to their default values:

• GroupStatus
• SegmentStatus
• Segmentation

Also, the MatchOptions field supports only MQMO_MATCH_MSG_ID and MQMO_MATCH_CORREL_ID. If you put unsupported values into these fields, the subsequent MQDestination.get() fails with MQRC_GMO_ERROR. If the queue manager does not support the Version 2 MQGMO structure, these fields are not updated after a successful MQDestination.get().
