Adding PLT entries

To automatically start and stop the transaction dump interface and region dump interface at CICS startup and shutdown, add the Abend-AID for CICS control programs to the CICS PLTPI and PLTSD. The PLT statements to automatically control Abend-AID for CICS are contained in member FXPLT in the installation sample library (CTL).

Note

  1. Program CTCCJSTR activates and terminates the transaction dump interface. It is required to capture transaction dumps.
  2.  Program CTCCJRGN activates and terminates the region dump interface. It is required only if you want to capture a list of recently changed programs in the CICS DFHRPL concatenation. CTCCJRGN is not required to capture region dumps. Abend-AID for CICS does not interfere with standard IBM dump routines. It is required only to capture information about recently changed programs in the DFHRPL concatenation..
  3.  If the list of recently changed programs is captured, you can view it through the Abend-AID for CICS region dump display screens. Entering the CHANGES fast-path command displays the Program Change Summary. See Using-supplied-Abend-AID-for-CICS-transactions for information about manually starting the region dump interface.
  4.  Capturing the program change summary information adds a small amount of overhead to the dump capture process. Usually this amount is insignificant, although some customers have experienced a more severe performance impact. Performance is more degraded if you use the Binder. If you see any performance degradation at dump capture time, you can turn off the region dump interface while still leaving the transaction dump interface active.
  5.  We recommend that you include the DFHPLTSD table entry for CTCCJSTR to shut down the Abend-AID for CICS transaction dump interface prior to CICS termination. If AAON is not turned off before CICS terminates, a system A03 abend occurs in the transaction dump interface.
  6.  Place the Abend-AID for CICS statements after DFHDELIM in the PLTPI and before DFHDELIM in the PLTSD.
  7.  Ensure that all PLT programs terminate with an EXEC CICS RETURN command because CICS links to each PLT program via a macro-level link. Failure to terminate each PLT program with a RETURN command can mean that EXEC CICS handle condition commands from previous PLT programs may remain active when subsequent PLT programs are run.

    This situation may occur with third-party vendor products.
