2.8.3.6 Coupling Facility Configuration


The Coupling Facility Configuration report tracks the
coupling facility activity in terms of utilization, structure
configuration and request activity.  A sample report is
shown in Figure 2-214.

REPORT OPTIONS

The Coupling Facility Configuration report supports standard
time selection options, SYSID and/or XCF System selection,
and specific XCF Structure selection.  These selection
options are discussed in Sections 2.8.5 and 2.8.5.5.

DATA ELEMENTS

The elements reported are divided into three categories:

  o  CF CPU Activity
  o  CF Configuration
  o  CF Request Activity


CF CPU ACTIVITY

The CPU Activity elements describe the utilization of
processing power on the coupling facility itself.  These
measures are repeated for each structure that was selected
for reporting.



AVG           The average number of processors on this
PROCESSORS:   Coupling Facility during the time period shown:
              CFPAVCPU.

AVG %         The average percent busy for the processors on
PROCESSOR     this Coupling Facility during the time period
BUSY:         shown:  CFPPCBSY.

AVG %         The average percent wait time for the
PROCESSOR     processors on the Coupling Facility during the
WAIT:         time period shown:  CFPPCWAT.

PERCENT CF    The percentage of intervals (RMF recording
CONNECTED:    intervals) during which the Coupling Facility
              was connected to the reporting system at the
              end of them measurement interval:  CFPPCCON

MAX %         The maximum percent busy for the processors on
PROCESSOR     the Coupling Facility during the time period
BUSY:         shown:  CFPMXPCB

MAX %         The maximum percent wait time for the
PROCESSOR     processors on the Coupling Facility during the
WAIT:         time period shown:  CFPMXPCB


CF CONFIGURATION

These elements display storage available and allocated
information for the coupling facility and reported structure.
These items should be relatively static over the duration of
the analysis unless some sort of reconfiguration activity has
occurred.

AVG STORAGE   The average amount of storage defined on the
DEFINED:      coupling facility.  This includes both control
              and non-control storage:  CFPAVTSD.

AVG STORAGE   The average amount of free storage on the
FREE:         Coupling Facility during the time period shown.
              This includes both control and non-control
              storage:  CFPAVTSF.

AVG CNTL      The average amount of control storage defined
STG DEFINED:  on the Coupling Facility during the time period
              shown.  The difference between this value and
              the average storage defined represents the
              average non-control storage:  CFPAVTSD.

AVG CNTL      The average amount of free control storage on
STG FREE:     the Coupling Facility during the time period
              shown:  CFPAVCSF.

AVG           The average size of the reported structure
STRUCTURE     during the time period shown:  CFSAVSIZ.
SIZE:


CF REQUEST ACTIVITY

The elements reported in this section reflect the request
activity associated with the specific structure defined to
the coupling facility and being reported on in the analysis.

% STRUCTURE   The percentage of intervals (RMF recording
CONNECT:      intervals) during the reported time period, in
              which the structure was connected to the system
              at the end of the interval:  CFRPCCON

ASYNC         The average number of asynchronous requests per
REQS/SEC:     second during the reported time period from the
              reporting system using the Coupling Facility
              structure:  CFRPSARC.

SYNCH         The average number of synchronous requests per
REQS/SEC:     second during the reported time period from the
              reporting system using the Coupling Facility
              structure:  CFRPSSRC.

QUEUED        The average number of queued requests per
REQS/SEC:     second during the reported time period from the
              reporting system using the Coupling Facility
              structure:  CFRPSQRC.

REQS/SEC      The average number of requests completed per
COMPLETED:    second during the reported time period
              originating on the reporting system:  CFRPSRQC.

DUMP DELAYED  The average number of request per second that
REQS/SEC:     were delayed due to dump serialization
              activity on the Coupling Facility:  CFRPSDRC.


AVG SVC       The average service time for handling the
TIME ASYNCH:  asynchronous request activity from the
              reporting system using this Coupling Facility
              structure:  CFRAVATM.

AVG SVC       The average service time for handling the
TIME SYNCH:   synchronous request activity from the reporting
              system using this Coupling Facility structure:
              CFRAVSTM.

AVG SVC       The average service time for handling the
TIME QUEUED:  queued request activity from the reporting
              system using this Coupling Facility structure:
              CFRAVQTM.

DUMP SER      The average number of Coupling Facility
DELAY RATE:   requests per second, that were delayed because
              dump serialization was in process during the
              time period shown:  CFRPSDUQ

HI PRI        The average number of Coupling Facility high
REQ RATE:     priority requests that were queued, per second,
              during the time period shown:  CFRPSHPQ

LO PRI        The average number of Coupling Facility low
REQ RATE:     priority requests that were queued, per second,
              during the time period shown:  CFRPSLPQ
