    This APAR provides the RMF support for High Performance FICON
    for System z (zHPF) comprising of:
    - Extended channel measurement group 2 data in
      - SMF record 73 (*)
      - SMF record 79 subtype 12 (**)
    - New report fields about FICON and zHPF activity in the
      RMF Postprocessor Channel Path Activity report (*)
    - New Postprocessor Overview conditions for SMF record 73 (*)
    - New report fields about FICON and zHPF activity in the
      Monitor II and Monitor III Channel Path reports (**)
    - Higher precision of I/O service times in Postprocessor and
      and Monitor II Device Activity reports (*)
    
    In addition, this APAR provides further enhancements for
    HiperDispatch comprising of:
    - New polarization indicators in the PR/SM Logical Processor
      Data section of SMF record 70 subtype 1 (*)
    - The SYSTEM ADDRESS SPACE ANALYSIS section of the RMF
      Postprocessor CPU Activity report is enhanced.
      The distribution of the In Ready queue is done based on
      the number of processors being ONLINE. With this APAR and
      HiperDispatch active, the distribution is based on the number
      of processors ONLINE AND NOT PARKED. This also affects SMF
      record fields SMF70Q00 to SMF70Q12 as described below. (*)
    
    Besides this support for System z10, this APAR also enhances
    SMF record 74 subtype 4 (CF Activity). The partition identifier
    of the CF is added to the Local CF Data section as described
    below. (**)
    
    (*)  provided for z/OS V1.7 RMF and up
    (**) provided for z/OS V1.8 RMF and up
    .
    >>>>>> CHANNEL PATH ACTIVITY REPORTS <<<<<<
    
    The Postprocessor Channel Path Activity report is extended
    by following new report fields:
    
    FICON OPERATIONS
    RATE   - Number of native FICON operations per second.
    ACTIVE - The average number of native FICON operations
             that are concurrenlty active.
    DEFER  - Number of deferred native FICON operations per
             second. This is the number of operations that
             could not be initiated by the channel due to
             lack of available resources.
    
    ZHPF OPERATIONS
    RATE   - Number of zHPF operations per second.
    ACTIVE - The average number of zHPF operations that are
             concurrenlty active.
    DEFER  - Number of deferred zHPF operations per second.
             This is the number of operations that could not
             be initiated by the channel due to lack of
             available resources.
    
    The Monitor II and Monitor III Channel Path Activity reports
    display following new fields:
    
    FICON OPS Rate    The rate of native FICON operations.
    
    FICON OPS Actv    The average number of native FICON
                      operations that are concurrently active.
    
    zHPF OPS Rate     The rate of native zHPF (High Performance
                      FICON) operations.
    
    zHPF OPS Actv     The average number of native zHPF (High
                      Performance FICON) operations that are
                      concurrently active.
    
    Because of the limited space on the ISPF report screens, these
    new fields replace the fields which were available for
    HiperSockets (MSG Rate, MSG Size, Send Fail, and Recv Fail).
    For Monitor III, the fields available for HiperSockets can be
    displayed by customizing the CHANNEL report with the Monitor
    III Utility.
    
    >>>>>> DEVICE ACTIVITY REPORTS <<<<<<
    
    The number of decimal places for the I/O service times is
    increased. The values in units of milliseconds are formatted
    with up to three decimal places now. Following report fields
    are affected in the Postprocessor DEVICE and SDEVICE Activity
    and the Monitor II Device Activity reports:  RESP TIME, IOSQ
    TIME, CMR DLY, DB DLY, PEND TIME, DISC TIME, and CONN TIME
