2.6.1 Usage Guidelines

 
The Coupling Facility Planning Sample Application provides a
capacity planning database file with the database elements
necessary for tracking, reporting, and forecasting the usage
and activity associated with the Enhanced SYSPLEX Coupling
Facility.  The information for this sample application is
derived from either the DETAIL, DAYS, WEEKS, or MONTHS
timespan of the CA MICS CF/XES Configuration and Activity
file (HARCFP).
 
The Coupling Facility Planning Sample Application permits
your installation to track and forecast Coupling Facility
usage and activity at a high level of summarization (that is,
at the SYSID and ZONE, HOUR or DAYNAME level) for Coupling
Facilities.  Because the data is derived from the HARCFP
file, this sample application provides information about each
unique Coupling Facility from each recording RMF's point of
view.
 
Coupling Facility Groups
 
Three CAPAPU elements, defined below, are used to keep the
granularity of the capacity database at the Coupling Facility
level. In addition to these three keys, the file is also
summarized by the SYSID that did the RMF recording.
 
   CAPAPU  -  SYSPLEX Identifier (SYSPLEX)
   CAPAPU2 -  Coupling Facility Name (CFYCFNM)
   CAPAPU3 -  System using CF (CFYSYSNM)
 
The Coupling Facility Planning Sample Application allows you
to modify the setting of these CAPAPU fields by using the
CAPAPU exit. Using this exit is optional, and only needed if
you want to modify the level of granularity of the Coupling
Facility capacity planning database.
