4.4.4.2 Compression Recommendation Reports

The compression recommendation reports enable you to maximize
your use of compression.  The reports are the

  1 - Compression Recommendation Report
  2 - Library Allocation Analysis Report
  3 - COMPRESS Parameter Member Update Report

and are described in the sections following this
introduction.

To produce the Compression Recommendation Reports, choose
option 2 from the CA MICS Administrator Utilities menu
(MWF;5;4;2).  The following panel is displayed:

Unit Database ID        the one-character identifier assigned
                        to the unit on which you want to
                        report.  A list of valid values for
                        your site is available by placing
                        a question mark (?) in the field.

Analyze:                Y (Yes) or N (No). Defaults to Y.
 Detail timespan        These fields enable you to control
 Days timespan          the extent to which you want to
 Weeks timespan         report on the effects of implementing
 Months timespan        compression.  For example, if you are
 Years timespan         not interested in compressing Years
                        timespan data, set its Analyze value
                        to N.

Percent saving          a number ranging from 0.00 to 99.99.
lower limit             This is the percentage savings that
                        limits which files are chosen for
                        compression.  (A file is selected for
                        compression if it contributes at
                        least this amount of savings toward
                        the total amount of space consumed by
                        the uncompressed timespan files.)
                        Use the information from the
                        Compression Candidacy Report to help
                        you choose a value for this field.

Limit reports to:       three-character product identifiers,
 Products               three-character information area
 Information areas      identifiers, or six-character file
 Files                  identifiers.  These fields enable you
                        to restrict the reports to specific
                        products, information areas, or
                        files.

                        Note:  if you use choose to limit the
                        reports, information about the
                        products, information areas, and
                        files that are not selected are
                        accounted for in the "Overhead space"
                        category.

                        For example, if your site heavily
                        uses the CICS Analyzer and you want
                        to implement compression in phases,
                        you might choose to implement
                        compression first for the CICS
                        Analyzer.  Specify CIC in the
                        Products field to report on the
                        effects of implementing compression
                        on this product's files.
