Problem summary

• ****************************************************************
  * USERS AFFECTED: All users that use DRF version 3 release     *
  *                 one might be affected.                       *
  ****************************************************************
  * PROBLEM DESCRIPTION: When doing a PITR recovery using logs   *
  *                      created from a batch job, DRF ends with *
  *                      RC=0, but the Open Unit Of Recovery     *
  *                      Report shows open UORs even though the  *
  *                      PITR time is after the close of the     *
  *                      log. The result is that the recovered   *
  *                      database is incorrect, which is evident *
  *                      when running HPPC on the recovered      *
  *                      database.                               *

  ****************************************************************
  FRXRBUF0 was missing code in some paths, though it did exist in
  others. This code stores with the open UOR the PRILOG End Time
  of the Batch Log that contains the UOR.  When the UOR manager
  encounters an 06 Batch End log record it must match the Batch
  Log's PRILOG End Time in the 06 with PRILOG End Time stored with
  all open UORs so that all UORs for that batch log can be applied
  to the database.  Otherwise, the UOR would be left open, the
  database would not be updated and the OPEN UOR Report would
  reflect this.
  

Problem conclusion

  *** END IMS KEYWORDS ***
  FRXRBUF0 is modified to fix the problem.
