Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: EXEC CICS DELETE FILE(filename) GENERIC *
  *                      suffers AFCV abend.                     *
  ****************************************************************
  A CICS application program is accessing a VSAM RLS file
  which is using replication logging.
  The application issues EXEC CICS DELETE FILE(filename) GENERIC.
  CICS calls VSAM RLS, which places a lock on the deleted record.
  Later, CICS does not tell VSAM RLS to release the lock which
  it is holding on the record, and so the record remains locked.
  Subsequent transactions attempt to write a new record using
  the same RIDFLD, and wait within VSAM RLS for the lock to
  be released.
  CICS detects that the transaction is waiting too long for
  VSAM RLS to reply, and abends the transaction AFCV.

Problem conclusion

• DFHFCRS has been changed to issue 'lite' ENDREQ calls to
  VSAM RLS at appropriate points.
  .
  PH17079 corrects a problem where AFCV abends may be returned
  when issuing EXEC CICS DELETE GENERIC commands against the last
  record in a VSAM Control Interval.  To ensure that VSAM RLS
  releases its record lock in all such cases, please apply the
  corrective service from VSAM RLS APAR OA58274 too.
