Adding the required programs to the shutdown PLT

To ensure that all Z Abend Investigator activity is correctly terminated, it is necessary to add the following entry to your CICS® shutdown PLT:

DFHPLT TYPE=ENTRY,PROGRAM=HFZPLT

The entry should be added before the DFHDELIM entry (shutdown phase 1).

As well as ensuring correct Z Abend Investigator termination, HFZPLT also disables Z Abend Investigator 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 HFZPLT to your shutdown PLT. Note that it is then possible for system 33E abends to occur during shutdown.

If the Z Abend Investigator 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=HFZPLTS
