PK90031: PROHIBIT AUTHORIZATION IN DBRC FLAG LEFT ON WHEN DOING A RECOVER ON HALDB TO LASTIC

APAR status

• Closed as program error.

Error description

• /DBR GLOBAL turns PROHIBIT AUTH ON. /STA GLOBAL turns PROHIBIT
  AUTH OFF. At (RECOVER) START, DSPRWV00 returns the status of the
  PROHIBIT AUTH flag in the field rwcr_prohibit_auth.
  FRXTAU00 checks rwcr_prohibit_auth before calling IB and turns
  PROHIBIT AUTH OFF if it is ON. It calls DBRC to do this.
  After calling IB, it checks rwcr_prohibit_auth again and if it
  is on, calls DBRC again to turn the PROHIBIT AUTH flag back on.
  .
  In other words, we need the PROHIBIT AUTH flag off for IB so
  turn it off if needed. But we want to leave it in the same
  status it was before recovery started so we turn it back on if
  it was on to start with. But in this case it was not on to start
  with. It's only on because of the /DBR GLOBAL command we issued.
  This explanation only makes sense if we are issuing the /STA
  GLOBAL before FRXTAU00 turns it back on.
  Thesuggested fix is to reset the rwcr_prohibit_auth flag when we
  issue the /STA GLOGAL. This would prevent FRXTAU00 from turning
  on the PROHIBIT AUTH flag incorrectly.  The /STA GLOBAL command
  is documented to turn the PROHIBIT AUTH off in DBRC, so it is
  safe to reset the flag in DRF
