CA Gen supports two methods for invoking a CICS DPS application through WebSphere MQ. They are:
Dispatching each server manager directly makes use of the trigger monitor for CICS that is provided by IBM. Each server manager has its own local triggered application queue defined to WebSphere MQ, and each of these application queues must be associated with a WebSphere MQ process definition object that describes the application that eventually processes the messages placed upon the queue. For information about this type of DPC-to-DPS flow, see DPC-to-DPS Flow Using a z/OS CICS Trigger Monitor in the appendix “Flow Diagrams.”
Additionally, each triggered application queue must define the trigger event rules that cause placement of a trigger message into an initiation queue. A trigger monitor services those trigger messages delivered to one or more initiation queues. When a trigger message arrives on an initiation queue, the trigger monitor retrieves the trigger message and issues a command to activate the defined application. The trigger message contains detailed information, specifically the application queue name passed as data to the invoked DPS application. The invoked application opens the specified application queue and retrieves the request message. For more information about triggering, see the appropriate IBM documentation.
