Triggers

Triggers occur in both the CICS and IMS environments.

The following figure shows the triggers message flow:

  1. In a trigger, the request initiates within an application in the BES within the z/OS environment. In this figure, application 1 or 2 (6 or 7) initiates the request.
  2. The appropriate interface (5) within Substation ES receives the request and sends it to ESB Interface (4).
  3. ESB Interface (4) transforms it to a Rendezvous or Enterprise Message Service message, which is carried by the daemon or EMS server (3). From there, the message can be sent to TIBCO BusinessWorks (1) or other TIBCO messaging client applications(2).

For triggers, no result set or acknowledgment goes back to the initiator (6 or 7), hence no dotted arrows in the figure.
