Problem summary

  • ****************************************************************
    * USERS AFFECTED: All DB2 for zOS users of the CURRENT         *
    *                 OPTIMIZATION HINT special register           *
    *                 for remote applications                      *
    ****************************************************************
    * PROBLEM DESCRIPTION: The CURRENT OPTIMIZATION HINT           *
    *                      special register is set incorrectly     *
    *                      when using implicit DRDA or the JCC     *
    *                      properties.                             *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The setting of the CURRENT OPTIMIZATION HINT special register
    through implicit DRDA or through the JCC API does not set the
    special register correctly; garbage data is stored instead
    of the proper value.
    In addition, an error is not issued when a string longer than
    128 bytes is used to set CURRENT OPTIMIZATION HINT special
    register through an implicit DRDA connection or through the
    JCC API.
    

Problem conclusion

  • DB2 is modified to set the CURRENT OPTIMIZATION HINT special
    register correctly.  For strings longer than 128 bytes, DB2
    will now issue sqlcode -725.
