    Utilities, COPY or Recovery, requested DB2 buffer manager to
    open page set of segmented table space like partitioned table
    space. Buffer Manager will turn on an internal flag to reflect
    the special treatment.
    During log apply phase of the Utility, data manager honored the
    internal flag and treated the classic segmented table space as
    universal table space. As the consequence, UNDO insert or REDO
    delete made a pseudo delete record on the page, and caused the
    inconsistency.
    

Problem conclusion

  • DB2 code is modified to honor another flag which reflects the
    table space definition to detect whether the table space is
    partitioned or not, during utility log apply phase.
