    ****************************************************************
    An ABEND04E RC00C90101 can occur at location DSNITCUS 5002
    (ERQUAL5002) when range partitioning is used by sort for
    parallelism.
    
    If sort builds a workfile for range partitioning, it saves the
    final workfile in a separate structure, and as a result, it does
    not have the original final workfile pointer at the end of sort.
    If however, the final workfile pointer is available after sort,
    and this is for range partitioning with parallelism, the clean-
    up processing will try to delete this workfile which may no
    longer exist, causing the abend.
    
    Also, sort needs to correct the counter for the number of
    records in the final workfile if range partitioning is enabled.
    If range partitioning has been enabled, and sort went through
    the merge phase, this counter can double the actual value.
    

Problem conclusion

  • DB2 sort code has been modified to ensure that the final
    workfile has been cleared if range partitioning is enabled.
    
    Also, the counter for the number of records for range
    partitioning has been corrected if sort goes through the merge
    phase.
