  * PROBLEM DESCRIPTION: Autojournal write add complete records  *
  *                      may be out of sequence with writes to   *
  *                      an RLS ESDS.                            *

  * RECOMMENDATION:                                              *
  ****************************************************************
  On a busy system, it is possible for CICS tasks to interleave
  between calls to write to a non-recoverable RLS ESDS file,
  and the subsequent calls to journal the write-add-complete
  autojournal log record for the write operation.
  This can lead to the ESDS RBAs being autojournalled out
  of the order in which records were written to the file.
  This problem does not apply to recoverable files.

Problem conclusion

• DFHFCRS has been altered to acquire and hold the RLS end of data
  set lock for the duration of the request to write to VSAM and
  then journal the write-add-complete autojournal record.
  This is done by exploiting new function provided in VSAM RLS
  APARs OA37812 and OA37814. These APARs must also be applied to
  enable the function provided in this APAR.
  This change affects only non-recoverable RLS ESDS files, which
  log write-add-complete autojournal records, and specify
  the JNLSYNCWRITE(YES) option.
