2.2.8 Requirements

The Real Storage Management Analysis reports let you track
the allocation of real storage on a monthly, weekly, daily,
or hourly level.  Paging and swapping workloads are reported
to allow analysis of the relation between real storage
allocation and the operation of the page/swap subsystem.
Real storage requirements at the performance group level are
reported to help you in evaluating the impact of new
applications or users, as well as the growth of existing
applications.  Swapping statistics are reported to assist you
in investigating swapping overhead.

Figure 2-66 shows the CA MICS files and timespan levels that
must be maintained at your installation in order to produce
all of the Real Storage Management Analysis reports.

  Figure 2-66. RSM Analysis CA MICS File Requirements


The following is a list of files required to run each
individual report:

o  System Storage Usage Report - SCPPAG

o  Private Storage Usage Report - WLMSEC or WLM_EC

o  Swap Analysis Report - SCPSWP

Only one level is required for the CA MICS RMF product files
(for example, DETAIL, DAYS, WEEKS, or MONTHS), depending on
the timespan you specify during inquiry definition.

The number of cycles that are maintained at your site for
each of the CA MICS files in Figure 2-66 determines the time
frame for which you can produce RSM Analysis reports and
plots.
