Message Summary attributes Use the Message Summary attributes to detect problems with messages. This group provides the backout count (which if high can indicate a problem), the correlation and message IDs, the message expiration time, the message length, message type (which can be request, reply, report, or datagram), persistence (which indicates whether the message is recoverable), priority (which can be used for selective retrieval), date and time the message was created, and the reply-to queue and queue manager names. These attributes are informational only; they cannot be used to create situations. If multiple headers are generated, subsequent headers are prefixed with the IBM® WebSphere® MQ ID of the associated header. For example, subsequent dead letter queue headers are prefixed with DLH and subsequent transmit queue headers are prefixed with XQH.
