    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When parallelism is enabled, if the leading table of a join
    uses list prefetch on a DPSI index and there is no sort for
    the RIDs, the query could run into 04E abends or incorrect
    output.  The symptom is data dependent.

Problem conclusion

  • The described problem is solved.
    
    Since the problem is data dependent, there can be cases that
    have the error but are working fine.  After applying the APAR,
    these cases may see access path changes and hence performance
    changes.
