PH15716: CPSM TRANSACTION COSH BEING SUBMITTED DURING CICS 5.5 SHUTDOWN UNDER THE REGION USERID

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You upgrade to CICS 5.5, and find that your region userid is
  now invoking transaction COSH during shutdown, and you receive
  a DFHAC2003 and DFHXS1111 message.
  .
  COSH is used to terminate the CPSM MAS agent code. Invoking
  COSH during shutdown was added at CICS 5.5 to help speed up
  region termination time. It has had unintended consequences
  though.
  .
  This early shutdown is also preventing customers from running
  CPSM API programs during PLTSD processing, since CPSM is no
  longer active in the region by that time.
  .

Local fix

• For the security issue, temporarily allow your CICS region
  userid to access the COSH transaction.
  For running CPSM API programs during shutdown, there is no
  current workaround.

  Messages DFHXS1111 and DFHAC2003 issued during shutdown
  processing after upgrading to CICS 5.5.
  
  Additionally issuing COSH in DFHSTP has shutdown the MAS agent
  code before PLTSD processing so CPSM API requests are failing.

Problem conclusion

• The system termination program no longer attaches the COSH
  transaction.  DFHSTP will close WLMHEALTH, preventing CICSPlex
  SM from routing more work to this target region.
