2.5.7 Requirements

The Virtual Storage Management Analysis reports and plots
enable you to track the allocation of virtual storage on a
monthly, weekly, daily, hourly, or interval basis.  Virtual
storage requirements at the job or step level are reported to
help you in evaluating the impact of new applications or
users, or the growth of existing applications.

Figure 2-190 shows the CA MICS files and timespan levels
that must be maintained at your installation in order to
produce all of the Virtual Storage Management Analysis
reports and plots.

  Figure 2-190. VSM Analysis CA MICS File Requirements


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

    o  System Storage Usage Report - SCPVSM
    o  Common Area Storage Usage Report - SCPVSM
    o  Private Storage Usage Report - SCPVSU
    o  System Storage Usage Plot - SCPVSM
    o  Private Storage Usage Plot - SCPVSU

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

The number of cycles that are maintained at your installation
for each of the CA MICS files in Figure 2-190 determines the
time frame for which you can produce VSM Analysis reports and
plots.
