PK58555: RECOVERY DOES NOT USE THE ICR UNLESS RCVTIME IS EQUAL TO OR LATER THAN THE ICR STOPTIME.

APAR status

• Closed as program error.

Error description

• Using DRF to create ICR, copy ends with the copy registered to
  DBRC with a Runtime (timestamp of endtime from last SLDS used as
  input) and a Stoptime (the real time that IC took place). A
  later DRF recovery only used that ICR if RCVTIME is equal or
  later than the ICR Stoptime.  Stoptime of such ICR has no
  meaning for recovery, I would better expect DRF to use the
  Runtime.

  ****************************************************************
  DRF Version 3 Release 1 generates incremental image copies with
  the OUTPUT(ICR) function. If the database is in use when the IC
  is generated, it is recorded with DBRC as concurrent (CIC). The
  RUNTIME of the IC is the STOPTIME of the last SLDS used, and
  the STOPTIME is the current time that the OUTPUT(ICR) was run.
  .
  After the database was stopped, a timestamp recovery was
  attempted to a time after the runtime of the IC, but earlier
  than the STOPTIME. Because the STOPTIME was greater than the
  RCVTIME, DRF used an earlier IC, rejecting the latest IC.
  

Problem conclusion

•  AIDS: RIDS/UTIL RIDS/DBS DBS/UTIL
    GEN:
  
  *** END IMS KEYWORDS ***
  DRF has changed to record the STOPTIME of a concurrent image
  copy created using the OUTPUT(ICR) function as one tenth of a
  second greater than the RUNTIME.
