  * PROBLEM DESCRIPTION: Data free space and pointer errors      *
  *                      were identified when running a PITR     *
  *                      DRF recovery which include logs.        *
  ****************************************************************
  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  Data integrity issues were identified with a DRF PITR recovery
  including logs.  In this type of scenario, DRF calls an
  internal routine to manage FSE from the Space Manangement
  Section of a log record.  This is done instead of applying the
  update in the Redo section.
  

Problem conclusion

•  AIDS: RIDS/UTIL RIDS/DBS DBS/UTIL
    DEP: NONE
    GEN:
  
  *** END IMS KEYWORDS ***
  FRXIILR is changed to apply updates from the Redo Section of the
  log records instead of stepping through the FSE Space Management
  Section.
  
  FRXIOCN0, FRXIVCN0, FRXIOSM0, and FRXIVSM0 are recompiled to
  pick up this change.
