Adding the required programs to the shutdown PLT

To ensure that all Fault Analyzer activity is correctly terminated, it is necessary to add the following entry to your CICS® shutdown PLT: 
DFHPLT TYPE=ENTRY,PROGRAM=IDIPLT
The entry should be added before the DFHDELIM entry (shutdown phase 1).

As well as ensuring correct Fault Analyzer termination, IDIPLT also disables Fault Analyzer in all the currently enabled CICS® exit points. This disablement prevents any subsequent abend analysis occurring during CICS® shutdown. If analysis is required during shutdown, then do not add IDIPLT to your shutdown PLT. Note that it is then possible for system 33E abends to occur during shutdown.

If the Fault Analyzer SDUMP screening feature has been installed you can optionally add a corresponding entry to the CICS SHUTDOWN PLT to disable this feature during CICS® shutdown:
DFHPLT TYPE=ENTRY,PROGRAM=IDIPLTS
