Changing a Datacom Source Table Definition

Changing a Datacom Source Table Definition

If you change the structure of a Datacom table that is registered for change data capture, use this procedure to retain access to previously captured change data and capture data under the new structure definition.
  1. Stop all update activity on the Datacom database.
  2. Ensure that PowerExchange processes all changes that occurred under the old schema.
  3. Change the Datacom table schema, and restart Datacom.
  4. Create a new PowerExchange capture registration that reflects the schema changes.
  5. Restart the Datacom table-based ECCR.
  6. Allow update activity to the Datacom database to resume.
