OA43003: POSSIBLE INCORRECT RBA RETURNED AFTER ESDS PUT UPDATE OR DELETE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• For ESDS processing, it is possible for the RBA to be corrupted
  by application programs after it's initially passeed in
  correctly. An application program specifies the correct RBA for
  a GET UPDATE request, VSAM RLS processes the GET UPDATE with the
  correct RBA successfully, then the application somehow corrupts
  the RBA, possibly by mistake, followed by a PUT UPDATE request.
  RLS also processes the PUT UPDATE successfully since RBA is not
  required. However, the incorrect RBA is returned at the end of
  the processing.
  

Local fix

• Avoid corrupting the RBA between requests.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: VSAM users running with non-keyed GET, PUT   *
  *                 and ERASE processing.                        *
  ****************************************************************
  * PROBLEM DESCRIPTION: A user application can corrupt the      *
  *                      input RBA value after a GET UPDate      *
  *                      request and the subsequent PUT or ERASE *
  *                      request can return with an incorrect    *
  *                      RBA value.                              *
  ****************************************************************
  * RECOMMENDATION: APPLY PTF                                    *
  ****************************************************************
  A user application specifies a correct RBA value for the GET
  UPDate request, then the application corrupts the RBA value.
  Since VSAM is already positioned to the record, the next PUT or
  ERASE request can run successfully but the returned RBA value in
  RPL area is still corrupted.
  

Problem conclusion

• VSAM will save the input RBA value for non-keyed GET request
  and the subsequent PUT or ERASE request will restore the RBA
  value in RPL before returning to user application.
