Problem summary

  • ****************************************************************
    * USERS AFFECTED: All DB2 9 and 10 for z/OS users of SQL       *
    *                 statements where global optimization is      *
    *                 applied.                                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: ABEND0C4 RC00000011 at the location     *
    *                      DSNXGRDS DSNXOGPS OFFSET2C6A could      *
    *                      happen for an SQL statement when global *
    *                      optimization is used. This ABEND is     *
    *                      dependent on the contents of some       *
    *                      random storage in the PSA, so normally  *
    *                      it won't happen.                        *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The failure can be observed in the following example:
    
    CREATE TABLE TBL1 (
      C1  INTEGER,
      C2  CHAR(10),
      C3  SMALLINT);
    
    CREATE TABLE TBL2 (
      C1  INTEGER,
      C2  CHAR(10),
      C3  SMALLINT);
    
    SELECT C1
    FROM TBL1 T1
    WHERE
    T1.C1  IN
    (SELECT C1  FROM TBL2 T2
     WHERE T2.C3=28
    )
    FOR FETCH ONLY
    WITH CS;
    
    DB2 did not correctly set the internally generated table name of
    the virtual table, which caused the ABEND.
    

Problem conclusion

  • DB2 has been modified to correctly process the virtual table
    setting, so there will be no ABEND.
