2.2.1 Functional Description

The Real Storage Management Analysis inquiries allow you to
track the utilization of real storage, resource (virtual
storage) requirements by workload, and system swapping
patterns.  Any supported CA MICS timespan and summarization
pattern can be implemented.

The System Storage Usage Report uses data from the MVS
Paging Activity File (SCPPAG).  Swap reports use data from
the CA MICS MVS Swapping Activity File (SCPSWP). Private
reporting as shown in the Private Storage Usage Report
examples base the input file requirements on specifications
you make during inquiry definition.  Private reporting can be
performed on any one of the two RMF workload files shown in
the table below.  Each file listed is comprised of workload
data representing a defined workload level: Service Class,
Service Class Period, and so on. The selection of the input
file during inquiry definition also determines the workload
level you wish to analyze.

WLMSEC - Service Class Resource Consumption
WLM_EC - Report Class Resource Consumption

The range of data that can be reported from a particular
CA MICS database depends on the timespans that were defined
for these files and the number of cycles defined in each
timespan.  If you are not familiar with the generation
options for the database unit containing the MVS SCP
Information Area, ask your system administrator for help.
