3.3.4 VM Management Objective Report Options

The Management Objective Reports assume that a set of
objectives related to the operation of VM have been
determined.  Often this may not be the case.  This section
describes how the management objectives may be specified in
the reporting process once they have been defined by
management.  First, however, a discussion of how the
objectives may be established is provided.

Numbers that will be used as management objectives should not
be defined without some analysis of the installation's
historical VM performance.

The CA MICS Database provides a useful information base for
analyzing historical performance.  We suggest that
statistical analysis procedures be used to study past
performance.

The same data sources mentioned above may be used to evaluate
the measures required in determining specific management
objectives.  Specifically, the SAS procedures UNIVARIATE and
FREQ may be used to provide a reasonable statistical analysis
of an individual measure, providing the analyst with mean,
standard deviation, and percentile values.  It is our opinion
that the percentile values may be the most applicable to the
process of determining the management objective's target
values.

The database files that should be used in analyzing VM
activity for purposes of establishing the VM Report Options
are listed according to the reports to which they apply:

    Daily   - &VMCD..VMXSGP01
    Weekly  - &VMCD..VMXSGP01-10
              (selects last week only)
    Monthly - &VMCD..VMXSGP01-06

In each case, the data source is the VM Performance Data
File, which contains data from the System Global Data File,
which contains VM performance data.

The last input essential in defining management objectives
for VM rests with the perspective of VM users as to what
minimum level of service, availability, and throughput they
require.

The integration of this information with data processing
management's own priorities and requirements will establish
the base for defining the management objectives for VM.

The following sections describe specifically how an
installation is able to specify the numerical values used in
these reports:
