APAR status

• Closed as program error.

Error description

• The transaction getting this error is CITS. This task got
  suspended for storage while it was trying to getmain storage
  for subpool ZCTCTTEL. The task times out and then abend ATCH
  processing starts. While DFHTBSS is in function SYNCPOINT, the
  0C4 happens due to the R6 being invalid.
  
  CITS has been called to autoinstall terminal 8588. During the
  INSTALL the URM, DFHZATX is called with the terminal CLASH flag
  on. The URM returned OK without changing the terminal ID.
  The ZGTI INQUIRE call returned a skeleton TCTTE address for
  8588 but for a different TOR. ZCQDL DELETE is called. During
  the deletion a surrogate TCTTE is needed. So DFHZTSP SKELEXP is
  called but failed to getmain storage for the surrogate TCTTE
  because of storage constrain. ZTSP abend ATCH which drive
  DFHZATS handle abend exit to issue message DFHZC6906 and
  re-issuing the abend.
  
  During task abend SYNCPOINT ROLLBACK call the builder module,
  DFHBSTZ READY PROC which expect a surrogate TCTTE pointer in
  the skeleton TCTTE. Since it is null the code program check.

  ****************************************************************
  Transaction CITS is installing a remote terminal and the
  terminal id duplicates an existing skeleton TCTTE.  During
  the process of replacing the skeleton, a CICS GETMAIN for a
  surrogate TCTTE fails because CICS is SOS, and the task is
  suspended.  The task is timed out before the storage can be
  acquired and abends ATCH.  As part of syncpoint rollback
  processing, DFHBSTZ is entered for the failed delete of the
  skeleton TCTTE, and incorrectly handles the case where there
  is no surrogate TCTTE address, which results in the 0C4/AKEA
  abend.
  

Problem conclusion

• DFHBSTZ has been changed to check whether there is surrogate
  TCTTE before referring to its address.
