PK07159: ABEND S00C4 IN EYU0CRCK OFFSET 714 WHEN SHUTTING DOWN CMAS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You shut down your CMAS and abend S00C4 occurs in EYU0CRCK
  at offset x'714'.
  
  Failing instruction is 58F0 F000, L R15,RACR_XSECBREN
  Reg15 is loaded from RegB+984 ( MOEB field SEC_XSEC_STRUCT ).
  The reg15 address is no longer in storage.
  
  In this case, an XLST task is in processing a request for the
  CMAS base table and a security check is made. However, the
  security subtask has quiesced due to the shutdown and has
  not updated the MOEB to remove the address to its control
  block.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICSPlex SM V3R1M0 Users.                *
  ****************************************************************
  * PROBLEM DESCRIPTION: An ABEND ASRA (S0C4) may occur at       *
  *                      offset x'6D4' in EYU0CRCK during CMAS   *
  *                      shutdown.                               *
  *                                                              *
  *                      The abend is more likely to occur if    *
  *                      API/WUI or EUI requests are still being *
  *                      processed when the CMAS is shutdown.    *
  ****************************************************************
  * RECOMMENDATION: After applying the PTF that resolves this    *
  *                 APAR, all CMASes must be recycled to pick    *
  *                 up the new code.  Note that the restarts     *
  *                 do not need to be done at the same time.     *
  ****************************************************************
  During CMAS initialization, CICSPlex SM establishes a subtask
  running program EYU9XSEC (XSEC - External Security Interface).
  XSEC is responsible for making all calls to the External
  Security Manager.
  
  EYU0CRCK (CRCK - Communications Security Access Check) is called
  to perform security checking in a CMAS. CRCK calls XSEC via a
  branch entry interface.
  
  During a CMAS shutdown, it is possible for the XSEC subtask to
  terminate before all tasks which may call CRCK are complete.  If
  this happens, the reported abend may occur.
  

Problem conclusion

• EYU0CRLT (CRLT - Security Services Long-Running Task) has been
  changed so that it no longer posts XSEC to terminate. Instead it
  indicates that the security interface is no longer available.
  
  Macro EYUBCRRR, which is used by CRCK and other methods to
  invoke XSEC, has been changed to abort processing if
  Communications termination is in progress.
  
  EYU9XSTC (XSTC - Interval Timing Control Task) has been changed
  to issue new message EYUXS1013I when XSEC has terminated.
  
  XSEC has been changed to update the XECB when it terminates
  normally. Additionally an error which may prevent XSEC from
  releasing its stack storage has been corrected.
