  The recording of image copies during the DRF process takes too
  long.
  

Problem conclusion

• When image copies are taken as part of the DRF process, all ICs
  will now be recorded in bulk as part of the end of job process
  instead of recording them separately by HPIC.
  
  DFSBRLSB
  --------
  Field BRLBRWCC is added and will contain the address of a list
  of image copies, mapped by DFSRWCC, to be recorded when the
  recovery completes.
  
  DFSRWCC
  -------
  rwcc_noclean - caller sets this flag to indicate that they do
  not want DBRC to perform IC cleanup when each IC is recorded for
  the recovery.
  
  Flags are added indicating the various types of ICs that can be
  recorded by the recovery process
  
  rwcc_entry_dual_dbname - DB name of the DBDS
  rwcc_entry_dual_ddname - DD name of the DBDS
  rwcc_entry_dual_ictime - IC run time
  rwcc_entry_dual_cictime - IC stop time for non-batch ICs
  rwcc_entry_icrcdcnt fix - IC record count
  
  rwcc_ic_err1 - flag indicating IC1 in error
  rwcc_ic_err2 - flag indicating IC2 in error
  
  DFSRWCR
  -------
  Added flag rwcr_NOTIFY_IC which is set by DBRC during the
  Recovery Start call indicating that this new support is present
  for recording all ICs in a batch at the end of Recovery
  processing.
  
  Field rwcr_cagrpname is set by DBRC on the Recovery Add call.
  This is the name of the Change Accumulation group in which the
  DBDS/Area belongs.
  
  DSPCCB
  ------
  Flag ccbnocln is set from flag rwcc_noclean during the Recovery
  End processing when the batch of ICs is recorded, indicating
  whether DBRC should bypass IC cleanup.
  
  DSPRWA00
  --------
  For Recovery Add processing, internal field RWA_CAGRPNM is set
  with the CA group name in which the DBDS/Area belongs.  This
  field is copied into rwcr_cagrpname when the RWCR is built for
  the caller.
  
  DSPRWV00
  --------
  Set flag rwcr_NOTIFY_IC during the Recovery Start call
  indicating that this new support is present for recording all
  ICs in a batch at the end of Recovery processing.
  
  All updates must be in the same commit scope for parallel
  access. A logical open must be done before starting the loop
  recording the batch of ICs.
  
  A logical open is done inside DSPURT00.  To avoid multiple
  enqueues (one per URT00 call), this logical open is also done
  for serial access.
  
  If BRLBRWCC is non-zero, the caller is indicating that they
  passed a batch of ICs to be recorded at the end of recovery
  processing.  DSPURT00 is called processing an internal NOTIFY.IC
  call for each IC that is to be recorded.  Before the call to
  DSPURT00, flag ccbnocln is set from flag rwcc_noclean indicating
  whether DSPURT00 should bypass IC cleanup.
  
  DSPRWV40
  --------
  This module is called during Recovery Start to build the list of
  ICs to be used by the recovery process.  This was changed to
  also return the number of records for the IC in
  rwcc_entry_icrcdcnt.
  
  DSPURT00
  --------
  Flag ccbnocln is set by internal NOTIFY.IC command callers that
  wish to bypass IC cleanup processing for performance reasons.
  DSPURT00 is changed to check this flag and bypass the call to
  DSPURCMH if indicated.
