Installing the MVS post-dump exit IDIXTSEL

The Fault Analyzer post-dump exit, IDIXTSEL, is installed in the MVS™ IEAVTSEL CSECT installation exit list. The exit, which is only invoked for SVC dumps, is installed by the USERMOD, IDIWTSEL. It is used to register CICS® system abend dumps, recovery fault recording SDUMPs, SLIP dumps, and to facilitate the capturing of Java™ faults.

To install this USERMOD, edit and submit the sample job IDIWTSEL. This sample job includes IDIXTSEL in the IEAVTSEL installation exit list. If you have other exits defined in this list, add the IDIXTSEL exit last.

For more information about adding exits to IEAVTSEL, see MVS™ Installation Exits.

To activate this change, IPL again or cancel the DUMPSRV address space so that it restarts with the new exit.

For dump registration via this exit to occur, it is necessary to also:
  • Start the Fault Analyzer IDIS subsystem. For information on this, see Using the Fault Analyzer IDIS subsystem.
  • Ensure that the default Fault Analyzer history file is a PDSE, or that an Analysis Control dump registration user exit is used to assign the registration fault entry to a PDSE history file. Dump registration fault entries can only be created in a PDSE history file.
For details about specifying a default history file name, see Parmlib member IDICNFxx.

For details about the Analysis Control dump registration user exit, see Analysis Control user exit (MVS SVC Dump registration).

See Verifying dump registration (IEAVTSEL) for information about how to test the dump registration setup.
