Implementation of Additive Changes

The additive and nonadditive schema upgrade files are generated separately by the Upgrade Wizard in the output directory you specify when you run the Database Configuration Wizard. Additive schema filenames include the additive identifier. Review these files to determine the schema changes that are applied by the additive schema process and edit them as necessary, for example, verify that they do not make changes that conflict with customizations.

Additive schema changes must first be applied in a production test environment which has the same data as the production environment, or data that is statistically similar to the data in the production environment. After generating and applying the additive schema files to the production test database, make sure users in the test environment can enter, query and delete records to check that applying additive schema changes to the database does not affect the way in which the existing version of the Siebel application works.
