First quiesce phase PLT programs

Programs that are to execute during the first quiesce stage of CICS® shutdown are specified in the first half of the PLT (before the DFHDELIM statement).

You must define first stage PLTSD programs to CICS. You can either define the programs statically, or use program autoinstall. You cannot define Java programs that run in a JVM server.

Although terminals are still available during the first quiesce stage, tasks that are started by terminal input are rejected unless they are named in a shutdown transaction list table (XLT), or are CICS-supplied transactions, such as CEMT, CSAC, CSTE, and CSNE, that are defined as SHUTDOWN(ENABLED) in the supplied definitions.

The first quiesce stage is complete when all of the first-stage PLT programs have executed, and when there are no user tasks in the system.

You cannot use Debug Tool to debug a PLT program during the first quiesce stage.
