  *                      results of an additional code review    *

  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  The following problems under IMS V9, IMS V10 and IMS V11 are
  fixed by this APAR:
  *
  1. If an AREA goes bad, a DMAC is not logged when closing the
     ADS, so a stop flag (DMACF1ST) is not propagated by a X'5957'
     log record. If the last ADS is bad and the X'5957' log record
     doesn't exist following a X'5922' log record, the stop flag
     (DMACF1ST) should be set with the X'5922' log record even if
     the AREA is registered to DBRC.
     When DFR processes the X'5922' log record, DFR checks a
     DOCLFLG2 field for the AREA which has only one ADS and is not
     registered to DBRC.
     If the AREA is registered to DBRC, 'DEDB AREA STATUS LIST'
     doesn't show 'STOPPED, NOPENED' status for the AREA which is
     stopped and closed due to a severe I/O error without creating
     EEQEs.
  *
  2. A '/STA DB xxxxxxxx ACCESS=xx' command closes all AREAs and
     writes X'5922' log records with a DOCLF2ST flag.
     When DFR processes the X'5922' log record, DFR checks a
     DOCLFLG2 field for the AREA which has only one ADS and is not
     registered to DBRC.
     If the DOCLF2ST flag is set on the DOCLFLG2 field, DFR sets
     a stop flag (DMACF1ST) on a DMAC.
     If an AREA is not registered to DBRC, a 'DEDB AREA STATUS
     LIST' shows 'STOPPED, NOPENED' status for the area which is
     opened and re-started by a '/STA DB xxxxxxxx ACCESS=xx'
     command.
  

Problem conclusion

• The following modules have been modified.
  (x = 9, A and B)
  *
  DFRL592x - This module was changed as follows.
             . A check of the registration flag to DBRC (DMACECD8)
               was deleted for a X'5922' log record process.
             . A DOCLF2ST flag that was set by '/STA DB xxxxxx
               ACCESS=xx' command was deleted from the judgment
               whether the AREA is stopped or not.
