CICS exit program

The CICS exit program (SOPCUSxx) is a method that is designed to include/exclude CICS transactions from optimization. The exit program enables ULTRAOPT to determine what transactions are running in CICS. When the Transids are identified, you can include/exclude transactions with the ULTRAOPT monitor.

Adding the exit program to the CICS PLTPI enables the exit program to run when a transaction is attached in CICS. The include/exclude table is used by ULTRAOPT to determine whether the transaction is included in, or excluded from, optimization. The exit program records Transids in the ULTRAOPT control blocks.

With SOPCINIT in the initialization PLT, you will see a message during initialization that the CICS Transid exit has been enabled successfully. Without the user exit, ULTRAOPT cannot track the transid and the include/exclude tables will not work.
