How CSQQTRMN detects errors

 

If the CSQQTRMN trigger monitor in WebSphere MQ for z/OS detects an error in the structure of a trigger message, or if it cannot start a program, it puts the trigger message on the dead-letter queue and sends a diagnostic message to a user specified LTERM (the default is MASTER). CSQQTRMN adds a dead-letter header structure (MQDLH) to the trigger message. It uses a feedback code in the Reason field of this structure to explain why it put the message on the dead-letter queue. If any other errors are detected, CSQQTRMN sends a diagnostic message to the specified LTERM, and then terminates.
