Error description

  • A non-message driven BMP is now reported as a single
    transaction, and statistics for each syncpoint are accumulated
    and reported at BMP end (or end of IMS log). In the case of
    certain Fast Path fields relating to buffer usage these values,
    when AVE/MIN/MAX is specified, do not contain meaningful
    results.

    A non-message driven BMP is now reported as a single
    transaction, and statistics for each syncpoint are
    accumulated and reported at BMP end (or end of IMS log).
    In the case of certain Fast Path fields relating to buffer
    usage these values, when AVE/MIN/MAX is specified, do not
    contain meaningful results.
    

Problem conclusion

  • 1.Form-based Summary processing for the following fields is
      modified for AVE/MIN/MAX processing:
       FPBFOTHR - Fast Path Buffers sent to OTHREAD
       FPNRDBFU - Fast Path number of MSDB and SDEP Buffers used
       FPNBFU   - Fast Path number of Normal Buffers used
       FPOBFU   - Fast Path number of Overflow Buffers used
       FPPBFU   - Fast Path Private Buffers used
       FPPBFU   - Fast Path Private Buffers used
       AVE      - The aggregate count is divided by the Fast Path
                  syncpoint count to give meaningful results
       MIN/MAX  - The Transaction Index record is extended to
                  provide for MIN/MAX results for the above fields
    2.The processing changes above are only applicable where the
      Fast Path syncpoint count for the transaction is > 1.
