PI91420: DFHSJ0001 ABEND AKEA OCCURRED AT OFFSET X'12C0' IN MODULE DFHSJIN WHEN TRYING TO START A NEW LIBERTY TASK

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Trying to start a new task on a liberty jvm server xxxxxx and
  get suspended for the JVM lock.
  During this suspend, the JVM server was disabling, as seen in
  the following message:
  DFHSJ0918 applid userid JVMSERVER xxxxxx is being disabled due
            to a PHASEOUT request.
  you receive the following errors when that new task wakes up,
  attempting to go to this disabling JVM server:
  .
  DFHSJ1004 applid userid  An exception has been thrown by the
            route method of class com/ibm/cics/router/Router.
  DFHSJ0001 applid An abend (code ---/AKEA) has occurred at
            offset X'12C0' in module DFHSJIN
            .
  Reviewing the dump from the SJ0001, we find a program check-
  ABEND0C4 occurred on a T8 TCB, in module DFHSJSA.  Code there
  assumes we have a Task Transaction environment, attempts
  to retrieve the TCA address from the TASENTRY control block.
  Since we do not have a transaction environment yet, there
  is not a TCA, which leads to this program check.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Abend AKEA at offset x'12C0' in module  *
  *                      DFHSJIN during failed Liberty startup.  *
  ****************************************************************
  The Liberty server fails to startup correctly. CICS sets the
  JVMSERVER to a disabled state.  While shutdown of the JVMSERVER
  is occurring a thread is allowed to execute within the JVMSERVER
  which fails to execute cleanly.  This causes CICS recovery to be
  driven on that thread. There is no TCA for this thread and so
  when CICS attempts to access the TCA the AKEA abend occurs.

Problem conclusion

• DFHSJTH has been changed to detect a JVMSERVER state change
  and not allocate a thread.  DFHSJSA has been updated to handle
  a thread without a TCA
