Design of the trigger server

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
  • 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.
