Error description

  • ABEND04E RC00C90207 in DSNIOW ERQUAL5003 while doing a
    RID list scan.  RID list scan incorrectly uses a deleted pointer
    record to look up an overflow record causing an abend as the
    overflow record is no longer there.                  (d75121)

    ****************************************************************
    * RECOMMENDATION: Apply corrective PTF when available          *
    ****************************************************************
    When a query using RID list scan to retrieve an overflow record,
    Db2 incorrectly uses a deleted pointer record to find the
    overflow record. Since the record deletion has been committed,
    Db2 runs into a failed sanity check during the lookup of the
    overflow record.
    

Problem conclusion

  • Db2 RID list scan logic has been fixed to skip a deleted pointer
    record when the deletion has been committed.
    

Temporary fix
