9.1.1.2 CICS Statistics Data

Beginning with CICS 3.1.1, CICS statistics are written to SMF
on an interval basis.  The statistics data have replaced CMF,
which no longer produces system global records, as the source
for system level information.  To accommodate this change,
the CICS Analyzer processes six global statistics records to
populate the CICCSY (CICS System Activity) file with
information previously obtained from CMF.  This processing is
done for CMF input at CICS 3.1.1 and higher releases.

The six global statistics records are:

 o Dispatcher (type 57, 59 and 60)
 o Loader (type 27)
 o Storage manager task subpool (type 8)
 o Storage manager (type 9)
 o Temporary storage (type 48)
 o Transient data (type 45)

The default SMF recording interval for CICS statistics is 3
hours.  For CA MICS processing, a maximum of 1 hour is
required; otherwise, the CICCSY file at the DAYS timespan
will contain missing values for observations during the hour
when no statistics records are found.

During DAY040 input processing, the CICS Analyzer creates a
work file for each of the above statistics records.  At end
of input, the files are merged and written to the CICCSY work
file, which is then sorted, summarized, and saved in the
CA MICS data base at various timespans.  All statistics work
files, with the exception of the dispatcher file (CICGDP),
are deleted at the end of DAY040 processing.  The reason for
keeping the CICGDP file is to calculate delta CPU value for
each interval.  Only one cycle of the CICGDP file is kept at
the DETAIL timespan.
