Release 10.1A: OpenEdge Deployment:
Managing 4GL Applications

Modifying the application database

Upgrading is more complicated when you have to change the database schema. If you are upgrading with unencrypted source, encrypted source, or CRC-based r-code, you can supply an incremental .df file and copies of the modified procedures.

If you are upgrading with time-stamp-based r-code, you must supply the following:

A new empty application database that includes the modified tables, fields, and indexes.
Precompiled versions of all modified procedures.
Dump/load utilities that will dump the user’s data and definitions and load them into the new empty database.
