Installation: When IBM SDK for z/OS 1.4.2 is upgraded to SR9, WebSphere Application Server for z/OS can no longer be terminated cleanly
 Flash (Alert)
 
Abstract
This issue is specific to IBM® SDK for z/OS 1.4.2 SR9 only and IBM® WebSphere® Application Server for z/OS versions (5.0, 5.1 and 6.0) that use this IBM SDK level.

When STOP is issued for a WebSphere Application Server on z/OS and IBM SDK for z/OS 1.4.2 SR9 is being used, the application server may generate an S0C4 abend and a number of TDUMPs (depending on how many worker threads the server is configured). The dumps will show that WebSphere Application Server for z/OS runtime worker threads are failing during termination. The threads will have the following traceback:

cleanUpThread
CEEVROND
CEEUCALL
CEEOXCTD
CEEOPE
CEEVH2OS
pthread_exit
SR_ExecutionRoutine
 
Content
Thread Exit verification code added to the JVM exposed compatibility issues with termination sequence used by WebSphere Application Server during shutdown.

Solution

WebSphere Application Server for z/OS V5.0 and V5.1

Select one of the following actions.

  • Download IBM SDK for z/OS 1.4.2 SR9a (APAR PK50801 - PTF UK28320) which will disable the new SDK code by default.
  • [5.1 only] Apply WebSphere Application Server for z/OS APAR PK50710 (delivered in service level W510243, PTF UK30046).
  • Point WebSphere Application Server for z/OS to a pre-SR9 level of IBM SDK for z/OS 1.4.2.

WebSphere Application Server for z/OS V6.0

  • If using the SDK that is shipped with WebSphere Application Server for z/OS by default, this issue will NOT surface and no action is needed. WebSphere Application Server for z/OS ships IBM SDK for z/OS 1.4.2 SR9a level (not SR9) with 6.0.2.23. Fix packs prior to 6.0.2.23 of WebSphere Application Server for z/OS V6.0 shipped pre-SR9 level which did not have this problem.
  • If not using the SDK shipped with WebSphere Application Server for z/OS, follow one of the steps below. Note, you will know if you are not using the SDK shipped with WebSphere Application Server for z/OS if you see warning message BBOJ0095W in your joblog output.

    Select one of the following actions.

    • Download IBM SDK for z/OS 1.4.2 SR9a (APAR PK50801, PTF UK28320) which disables the new SDK code by default.
    • Apply WebSphere Application Server for z/OS APAR PK50711 (delivered in fix pack 6.0.2.24, PTF UK31684).
    • Point WebSphere Application Server for z/OS to a pre-SR9 level of IBM SDK for z/OS 1.4.2.
