Activating DSUM Support for Analyzer Files

General support for DSUM (exception daily summarization) is provided in the
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:

General support for DSUM (exception daily summarization) is provided in the
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 File Statement (FILE).
  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 Delete File From a Timespan and Delete File From Audit Archive Tape for deleting files and audit archives from a unit.
  4. Run sharedprefix.MICS.CNTL(VMCCGEN) to regenerate the
    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
MICS
Analyzer Option for VM/CMS is installed.
The steps described above must be followed to complete the activation of this support.
