CICS Application-Initiated Request Reply

In the CICS application-initiated request reply scenario, a CICS application initiates an external request that expects a response by linking to a supplied CICS program that passes the COMAREA to Substation ES, and then waits for a response for a predefined time.

The following figure shows the CICS application-initiated request reply scenario:

Currently, this scenario causes an affinity between the initiating CICS application program and the Substation ES that handles the request.
