Problem summary

    * PROBLEM DESCRIPTION: This APAR has the following fixes:      *
    *                      (1) An SQLCODE -950 is incorrectly      *
    *                          returned for an INSERT with         *
    *                          subselect that has a three part     *
    *                          name.                               *
    *                      (2) When zparm ACCELMODEL=YES,          *
    *                          GET_ACCEL_ARCHIVE=YES is            *
    *                          incorrectly allowed.                *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    (1) An SQLCODE -950 is incorrectly returned for an INSERT
        with subselect that has a three part name for remote
        tables when QUERY_ACCELERATION=ENABLE,
        ENABLE_WITH_FAILBACK, ELIGIBLE or ALL, or
        GET_ACCEL_ARCHIVE = YES.
        Execution of an SQL statement with a three part name on
        an accelerator is not supported, so the SQL statement
        will either execute on DB2 or return SQLCODE -4742
        depending on the values of QUERY_ACCELERATION and
        GET_ACCEL_ARCHIVE.
    
    (2) When subsystem parameter ACCELMODEL is set to YES, the
        subsystem parameter GET_ACCEL_ARCHIVE must be undefined or
        set to NO.  If GET_ACCEL_ARCHIVE is set to YES, then none
        of the accelerator modeling function will be enabled.

Problem conclusion

  • (1) Code is fixed to handle an SQL statement with a three part
        name properly.
    (2) Code is fixed to disallow setting zparm GET_ACCEL_ARCHIVE
        to YES when ACCELMODEL is set to YES.
