7.1.2.2 Activating DSUM Support for Analyzer Files

General support for DSUM (exception daily summarization) is
provided in the CA MICS Analyzer Option for VM/CMS.  This
support is provided to allow a site to reduce the size of the
online databases by eliminating the DETAIL timespan of a file
and retaining the DAYS timespan in its place.  This is
typically used when the detail information is not required
for reporting purposes.  To activate this support, the
following steps must be taken:

1 - The FILE statement for the product file for which this
    support is required must specify exception processing for
    the summarization from the DETAIL file to the DAYS file.
    For more information, see Section 4.2.4.2.1 of the System
    Modification Guide.

2 - Sharedprefix.MICS.SOURCE must contain a DSUM member for
    the file.  The name for this member is #fffDSUM, where
    fff is the three character identifier for the file.  See
    sharedprefix.MICS.SOURCE(#VMUDSUM) for an example of a
    DSUM routine.

3 - Change the FILE statement in VMCGENIN by changing the
    DAYS timespan indicator to E.  If the DETAIL timespan is
    being deactivated (by specifying N for the DETAIL
    timespan indicator), then the audit archive must also be
    deactivated.  Follow the checklists in Sections 6.2.2.1
    and 6.2.3.2 of the System Modification Guide for deleting
    files and audit archives from a unit.

4 - Run sharedprefix.MICS.CNTL(VMCCGEN) to regenerate the CA
    MICS Analyzer Option for VM/CMS.

5 - Regenerate the VM unit level support macros by running
    prefix.MICS.CNTL(VMCPGEN).

6 - If a file is enabled or disabled for a timespan,
    prefix.MICS.CNTL(CYCLEGEN) must be run in each unit that
    has VMC installed.

7 - Regenerate operation job DAILY. Job WEEKLY must be
    regenerated if audit archive was deactivated for the
    file.

DSUM support can be deactivated by changing the FILE
statement to its previous state, then running VMCCGEN and
VMCPGEN for each unit in which the CA MICS Analyzer Option
for VM/CMS is installed.

The steps described above must be followed to complete the
activation of this support.
