 Figure 11-8.  Workload Characterization Screen

The Workload Characterization screen lists the following
fields:

CA MICS file: The CA MICS file that contains the data
              elements that you wish to include in your
              workload characterization analysis. If you are
              uncertain of the correct file name, type a
              question mark (?) in this field to obtain a
              complete selection list for your installation.

Cycle(s):     The cycle or cycles of the CA MICS input file
              that are used in the analysis.  For most
              installations, there is one cycle of DETAIL
              CA MICS data for each day. You may specify a
              maximum of 21 cycles.

Database:     The database unit identifier(s) (up to five
              units) that contain the specified CA MICS file.
              An eight-character database unit name is
              displayed after you specify this identifier. If
              you are uncertain of which database unit the
              CA MICS file resides in, type a question mark
              (?)  in this field to obtain a complete
              selection list for your installation.

Analysis      The features (data elements) that are analyzed
based on:     by the clustering procedure.  You may define a
              maximum of ten features.  Cluster variables
              must be numeric.  These data elements may
              either be CA MICS data elements or non-CA MICS
              data elements.  If you specify non-CA MICS data
              elements, you must provide the SAS code to
              derive them via the exit available on the
              Extended Options Menu, Figure 11-9.

Report for    The data elements that will be detailed in the
each          Resource Consumption by Cluster Reports (see
cluster:      Section 11.3.3).  At a minimum, you will
              generally want to specify all of the data
              elements specified for the Analysis based on
              parameter.  In addition, you may specify other
              numeric data elements that you might find
              informative in the reports.  For example,
              clusters for a job class study might be
              developed using CPU time, tape mounts, and
              print lines as features.  You might also wish
              to report on tape EXCPs, tape drive occupied
              hours, disk EXCPS, and average elapsed time of
              the jobs assigned to the clusters.

              A maximum of ten report variable names may be
              specified.  Report variables must be numeric.
              These data elements may be either CA MICS data
              elements or non-CA MICS data elements. If non-
              CA MICS data elements are specified, you must
              provide the SAS code to derive them via the
              exit available on the Extended Options Menu,
              shown in Figure 11-9.

Date          The selection criteria for Date, Hour, Zone,
selection:    and SYSID to subset the data you are examining.
              You must enter date values in the ddmonyy
              format.

Specify       The specification for selecting extended
extended      options.  Select this option if you wish to
options:      specify additional parameters.
