Using the Upgrade Driver Program

The sequence of Application Engine sections that are run by an upgrade driver is maintained in the PS_PTIA_DCAEPGMS table. The Application Engine sections defined in the PS_PTIA_DCAEPGMS table are referred to as root sections.

There are two categories of Upgrade Groups:

• MAIN – Core Data Conversion

• DDL – Data Conversion sections that contain Drop Table Statements (only)

Upgrade groups contain one or more Application Engine sections that are ordered within the group by sequence number. The Application Engine program PTIADATACONV is used to run the MAIN and the DDL data conversion groups.

When data conversion is run using the PTIADATACONV Application Program, the sequence number is used to determine the “Relative Run Order” of Application Engine sections that reference the same table or tables, but not the “Absolute Run Order” of the upgrade group(s).
