9.2 Daily Update Processing Flow

The DAY010 step of the DAILY job processes information in the
following phases.

    Phase 1 - Input Raw Data
                   Formats the TSO/MON data.

    Phase 2 - Information Area Processing
                   Eliminates duplicate data, summarizes
                   device and step activity, and builds the
                   journal files using the Accounting and
                   Chargeback Product.

    Phase 3 - Data Base Time-Span Processing
                   Creates DAYS time-span files from DETAIL
                   and updates week-to-date and month-to-date
                   information where applicable.

    Phase 4 - File Aging
                   Ages the DETAIL and DAYS cycles, deleting
                   the oldest cycle.  Also replaces the
                   week-to-date and month-to-date cycles.

The sections that follow describe the general logic flow in
each of the phases, as well as the location of standard user
routines and user exits.  In the figures that follow, exits
that are user-modifiable are shown in boxes whose corners are
made of asterisks (*).
