Problem summary

  • ****************************************************************
    * USERS AFFECTED: All users of the DLDFREQ subsystem           *
    *                 parameter in DB2 10 for z/OS are affected    *
    *                 by this APAR.                                *
    ****************************************************************
    * PROBLEM DESCRIPTION: In DB2 10, the DLDFREQ parm accepts     *
    *                      settings other than NO, YES, and        *
    *                      integers from 0 - 32767.                *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    DLDFREQ specifies whether the level ID of a page set or
    partition is to be updated at DB2-determined checkpoint
    intervals.  Valid settings are ON and OFF but DLDFREQ also
    accepts a deprecated range of settings as integers from 0
    through 32767 where 0 corresponds to OFF and 1 though 32767
    corresponds to ON.
    
    Currently, an error in DSN6SYSP permits DLDFREQ to accept
    values outside these ranges.  When this happens, DLDFREQ is
    effectively set to ON.
    

Problem conclusion

  • In response, this APAR fixes DSN6SYSP so that DLDFREQ accepts
    only the documented settings of ON and OFF plus the deprecated
    settings of 0 - 32767.
