Design of the trigger server

The design of the trigger server is similar to that of the trigger monitor, with a few exceptions

The design of the trigger server is similar to that of the trigger monitor, except that the trigger server:

• Allows MQAT_CICS as well as MQAT_OS400 applications.
• Calls IBM i applications in its own job (or uses STRCICSUSR to start CICS applications) rather than submitting an IBM i job.
• For CICS applications, substitutes the EnvData, for example, to specify the CICS region, from the trigger message in the STRCICSUSR command.
• Opens the initiation queue for shared input, so that many trigger servers can run at the same time.

Note: Programs started by AMQSERV4 must not use the MQDISC call because this stops the trigger server. If programs started by AMQSERV4 use the MQCONN call, they get the MQRC_ALREADY_CONNECTED reason code. Parent topic: The Triggering sample programs
