PK48045: POINTER ERRORS AFTER DRF RECOVERY WITH HDAM DATABASE

APAR status

• Closed as program error.

Error description

• Pointer errors after DRF recovery with HDAM DB
  From the HPPC output the HI-U-RBA was calculated something like
  '8A2E4000'x.  DRF treated this as a signed value so it interpret
  -ed this as a negative number.
  This problem only applies to recoveries using SMS type ICs for
  VSAM databases.

  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  When processing SMS-type image copies for HDAM databases, DRF
  obtains the HI-U-RBA of the database data set to determine the
  end.  This is used to compare against the RBA from update
  records so updates may either be applied to existing database
  blocks or written out to extend the database.
  The HI-U-RBA is normally obtained as a fullword value.
  However, it was determined that in the event that the high-
  ordered-bit of the HI-U-RBA is on, DRF treated it as a negative
  value.
  

Problem conclusion

• AIDS: RIDS/UTIL RIDS/DBS DBS/UTIL
    DEP: NONE
    GEN:
  
  *** END IMS KEYWORDS ***
  FRXIVSM0 is changed to save the HI-U-RBA obtained from the
  database data set in a FIXED(32) field.  Originally it was
  being saved in a FIXED(31) field.
