Writing shutdown programs

Any program that is to run during CICS® shutdown must be defined in a program list table (PLT), and the PLT must be named on the program list table shutdown (PLTSD) system initialization parameter.

You can override the PLTSD value by using the Shutdown option from the CICS Explorer® Regions operations view or by providing a PLT name on the CEMT PERFORM SHUTDOWN command, or on the EXEC CICS PERFORM SHUTDOWN command. If a PLTSD program abends, sync point rollback occurs.
