Problem summary

  • ****************************************************************
    * USERS AFFECTED: All DB2 10 and DB2 11 Z/OS users of          *
    *                 IFC 306 with compressed data.                *
    ****************************************************************

    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    DB2 didn't properly serialize the operation between a IFC306
    thread and a thread that was Altering the table to add
    additional partitions. This caused inconsistency between some
    internal DB2 control blocks on the object. As a result,
    when DB2 tried to open a new partition of the object, some
    control blocks indicated the partition didn't exist and
    DB2 abend with RC00C20305.

Problem conclusion

  • Fixes made in DB2 to properly serialize the operation between
    a IFC306 thread and the thread Altering the table.
