Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You are running CICS Transaction server, using a recoverable
  coupling facility data table or CFDT.  You receive the
  following message when the CFDT server was recycled:
  DFHFC7115 The coupling facility data table server for pool xxxx
            has failed and restarted.
            One or more in-flight transactions which had made
            recoverable updates to coupling facility data tables
            residing in the pool will be abended.
  In this case there was a CECI transaction that had deleted a
  record from this file, and it was not abended.
  A CEMT INQuiry on the file, showed it
  was in Close Requested status, which is appropriate, given this
  CECI task was still active.
  The problem is, when the CECI task did end, the file still
  showed as Close Requested status, and never went to
  CLOSED status.

  This problem presented as a CFDT file being left in an unusable
  state of CLOSE REQUESTED .
  
  Task_A did a DELETE of a File_A record ( 000001 ) from a
  recoverable CFDT, Task_A was left INFLIGHT.  In doing this, FC
  ( File Control ) code set on bit FLAB_DO_NOT_CLOSE for File_A.
  
  The CFDT failed and was restarted.
  
  Task_A then attempted a READ of the same file, this abended
  ACFC due to a UOW_NOT_FOUND whilst attempting to perform a
  RESYNC_CFDT_POOL.  Task_A then attempted another READ which
  received a SYSIDERR.  At this point, FC code attempted to CLOSE
  File_A ( CLOSE REQUESTED ) but even after Task_A completed,
  File_A remained in a CLOSE REQUESTED state.  FC code was unable
  to properly close File_A because bit flab_do_not_close was
  still set to ON from the initial DELETE and prevented File_A
  from closing.
  

Problem conclusion

• DFHFCFR has been modified to correctly process the file CLOSE
  in the aforementioned scenario.
