Overview for MQTMC2

Purpose: When a trigger-monitor application retrieves a trigger message (MQTM) from an initiation queue, the trigger monitor might need to pass some or all of the information in the trigger message to the application that the trigger monitor starts.

Information that the started application might need includes QName, TriggerData, and UserData. The trigger monitor application can pass the MQTM structure directly to the started application, or pass an MQTMC2 structure instead, depending on what is permitted by the environment and convenient for the started application.

This structure is part of the IBM MQ Trigger Monitor Interface (TMI), which is one of the IBM MQ framework interfaces.

Character set and encoding: Character data in MQTMC2 is in the character set of the local queue manager; this is given by the CodedCharSetId queue manager attribute.

Usage: The MQTMC2 structure is very similar to the format of the MQTM structure. The difference is that the non-character fields in MQTM are changed in MQTMC2 to character fields of the same length, and the queue manager name is added at the end of the structure.

On z/OS, for an MQAT_IMS application that is started using the CSQQTRMN application, an MQTMC2 structure is made available to the started application.
On IBM i, the trigger monitor application provided with IBM MQ passes an MQTMC2 structure to the started application.
