2.3 Levels of Summarization

If you are new to CA MICS, you may not know that it provides
several views of your data and performs automatic
summarization of the data at each higher view.  The levels of
information include DETAIL, DAYS, WEEKS, and MONTHS.  The
DETAIL level contains the unsummarized data, but in a format
that is much easier to use than the original form.  At this
level you can get information about individual RMF intervals,
individual jobsteps, and individual data sets.  The DAYS
level is the first level of summarization.  It normally is
summarized by hour.  Therefore, if your RMF interval is 15
minutes, each hour record in the database will be
representative of four original interval records, but will
summarize the activity on your system for one hour.

Each file in each timespan can exist in several generations,
or cycles.  The number of cycles per file per timespan is
defined by your CA MICS System Administrator.  The number of
cycles kept is usually influenced by the amount of storage
space required by the file.  Larger files normally have fewer
cycles kept, to minimize the space requirements of CA MICS.
Many of the files used by CA MICS StorageMate are usually
small in size, so several cycles could be maintained with a
minimum of impact.

You should obtain the normal processing schedule for your
installation from your CA MICS System Administrator.  You can
then be assured that you are viewing and analyzing the data
you want.
