Modifying schemas
When you modify a schema you must complete several tasks to ensure that your changes are validated, saved, and applied to user databases.
Procedure
To
modify a schema and put the modifications into effect or to create
a new schema:
- Start the Designer.
- Create a test database (or multiple test databases) in the schema that you want to customize.
- Check out the schema that you want to customize, or create a new schema.
- Modify the schema, either by using the Designer to change elements of the schema, or by applying packages.
- Validate the customized schema using the Validate schema command in the Designer.
- Create a test configuration that specifies the test database (or multiple databases) for the schema.
- Run the test configuration and test your schema against the specified databases.
- Save work in progress.
- Check in the customized schema.
- Upgrade the user database with the modified schema.
