0C1 abend during CICS PLT processing after upgrading z/OS when using ATF

Technote (troubleshooting)


After upgrading to a new release of z/OS, you receive the following message in your CICS Transaction Server for z/OS region during PLT processing:

DFHAP0001 An abend (code 0C1/AKEA) has occurred at offset X'FFFFFFFF' in module TSTORPLT.


You are using Application Time Facility for z/OS (ATF) which was previously known as TICTOC. ATF program TSTORPLT is the first program in your PLT that is using Language Environment (LE). When the PLT program ends, CICS calls LE for Rununit_End_Invocation but control never came back to CICS from LE.

A system dump shows all of the CEE modules are running at a backlevel version of z/OS including CEEPLPKA and that the mismatch is causing the abend 0C1. An ATF library was in the RPL concatenation that contained the old LE modules.

Resolving the problem

Make sure the ATF libraries in your DFHRPL concatenation are running LE modules at your current z/OS level. See section 3.2 Using ATF with Language Environment in the Application Time Facility for z/OS Installation and Customization Guide (SC31-6922-03) for more information.

Contact ATF Support if you need additional assistance.

Note: You might copy the affected LE modules out of SCEERUN and into the ATF load library (SCIKLOAD) when you apply the ATF ZAPs. However, IBM recommends that you create a separate load library that contains the affected LE modules, rather than copying into a product library.
