9.1.3 Updating the HSM and HSB Information Areas


The Space Analyzer makes use of the standard database update
and summarization facilities of CA MICS to maintain its data
in the online and offline databases.   SMF format data
provided by VCC is supplied to CA MICS in the DAY095 step of
the DAILY database update job.

The daily update step:

  o  Reads and formats the raw data
  o  Maintains data integrity by eliminating duplicate data
  o  Adds new cycles to the DETAIL timespan
  o  Summarizes activity by hour for DAYS timespan
  o  Adds new cycles to the DAYS timespan
  o  Updates the week-to-date cycles
  o  Updates the month-to-date cycles

Figure 9-2 shows an overview of the daily update process.  A
more detailed description of DAY095 processing is presented
in Section 9.3.

Weekly  processing  is  performed  by the WEEK095 and WEEK300
steps.  The WEEK095 step splits the week-to-date files into a
new  week-to-date  and  a new weekly '01' cycle.  The WEEK300
step creates the weekly offline database files.

Monthly processing is performed by the MONTH095 and MONTH300
steps.  The MONTH095 step splits the month-to-date files into
a new month-to-date and a new monthly '01' cycle, and also
updates the year-to-date cycles.  The MONTH300 step creates
the monthly offline database files.

Yearly processing is performed by the YEAR095 step.  The
YEAR095 step splits the year-to-date files into a new year-
to-date and a new yearly '01' cycle.
