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.
