How the Message ID and Correlation ID are handled in a Transmission Queue

White Papers


Abstract

The objective of this techdoc is to show how the Message ID (MsgId) and the Correlation ID (CorrelId) in an MQ Message Descriptor (MQMD) are handled in a message that is sent from a Remote Queue Definition to a Transmission Queue, and from there to the destination queue.

Content

This document uses a visualization of WMQ message headers shown as envelopes to help explain the relationship between MsgId and CorrelId as messages go on and off a transmit queue.
