Group message support

The adapter for IBM® MQ supports retrieval of IBM® MQ group messages as data source objects. The group message feature allows multiple messages to be placed on a message queue while retaining an organizational connection through the GroupId field of the MQ Message Descriptor (MQMD).

  • A message group consists multiple logical messages.
  • A logical message consists of one or more physical messages.
  • When a logical message contains more than one physical message, the logical message is segmented. Each physical message is a segment.
  • Each logical message has the same GroupId and a distinct MsgSeqNumber.
  • Each physical message has distinct MQ Message Descriptor (MQMD).
  • Each segment has the same GroupId MsgSeqNumber and a distinct Offset.
