Changing an IDMS Source Schema

Changing an IDMS Source Schema

If you make schema changes to an IDMS source, use this procedure to retain access to historically captured data while capturing data in the new format.
  1. Stop all update activity against the IDMS database.
  2. Ensure that PowerExchange processed all changes that occurred under the old schema.
  3. Change the IDMS schema.
  4. Create a new PowerExchange capture registration that reflects the schema changes.
  5. Ensure that the updated schemas are in place in the PowerExchange copies of the IDMS libraries.
  6. Allow update activity to the IDMS database to resume.
  7. Restart PowerExchange processing.
