PH71413: JVMSERVER intermittently installed as disabled after a CICS warm start when the previous CICS region had the JVMSERVER enabled

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Intermittently, CICS incorrectly catalogues a JVMSERVER during
  shutdown. As a result, a subsequent CICS region which was
  brought up as a warm/auto start will install the JVMSERVER as
  disabled even if the JVMSERVER in the previous CICS region
  instance was enabled at the point of shutdown.
  
  Since the JVMSERVER is installed as disabled, no DFHSJ9015
  message occurs and no error occurs. Enabling the JVMSERVER
  which was installed as disabled works successfully.

  * PROBLEM DESCRIPTION: CICS occasionally may catalogue an      *
  *                      enabled JVMSERVER as disabled during    *
  *                      CICS shutdown.                          *
  ****************************************************************
  In rare cases during a CICS region shutdown with an enabled
  JVMSERVER, a timing window may be hit where the JVMSERVER
  completes its shutdown and is then issued with a further call to
  terminate which catalogues the JVMSERVER state. Since this
  occurred after the JVMSERVER has already disabled successfully
  as part of CICS shutdown, the state is incorrectly stored in the
  catalogue as DISABLED.
  
  A subsequent warm/auto start of the CICS region will
  then install the JVMSERVER as disabled, not honouring the
  correct enabled state of the JVMSERVER from before shutdown.
  

Problem conclusion

• CICS has been updated to ensure JVMSERVERs which are enabled up
  until the point of shutdown are not incorrectly catalogued as
  disabled.
