PK97880: CEXEXRTR REG6 POINTS TO STORAGE THAT HAS BEEN FREED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• This APAR will address the following problems:
  1) If an IMS Connect Port task abends, CEX module CEXEXRTR may
     also abend with 0C4 and R6 pointing to storage that has been
     freed. This is because CEX has been notified of the jobstep
     abend and is shutting down. There is a small window where an
     IMS Connect Port task may still be dispatched and encounter
     the storage that was freed during CEX shutdown.
  2) MSGCEX5538E running the Definition Maintenance Utility if the
     host name cannot be verified.
  3) MSGCEX5540E received when the CEX repository resides on
     another SYSPLEX.
  4) MSGCEX5538E and MSGCEX5540E should be changed to
     warnings.
  5) MSGCEX5006E ERROR DETECTED, RC0010 , RSN040D0327 during
     IMS Connect startup.

  This APAR is fixing the following:
  1. Message CEX5006E during IMS Connect Startup If HWSCFG=
  is located in a continuation of the PARM values in second
  JCL line.
  2. If an IMS Connect Port task abends, CEX module CEXEXRTR
  may also abend with 0C4 and R6 pointing to storage that
  has been freed. This is because CEX has been notified of
  the jobstep abend and is shutting down. There is a small
  window where an IMS Connect Port task may still be
  dispatched and encounter the storage that was freed during
  CEX shutdown.
  3. Running the Definition Maintenance Utility, message
  CEX5538E if the host name cannot be verified and message
  CEX5540E if the archive JCL dataset is not catalogued.
  

Problem conclusion

• 1. Corrected the parsing routine in CEXTECL to find the
  HWSCFG= keyword when it is located in a second
  continuation line of the PARM= string.
  2. Module CEXMAIN is changed to not free any control blocks
  that may be needed by CEXEXRTR. Since the region is
  in termination, the storage for the control block will
  be freed during region termination
  3. A new processing option is made available that will allow
  messages of this type to be ignored so that utility
  processing can proceed
