Add a Replicat for Oracle Database

A Replicat is a process that delivers data to a target database or technology. It reads the trail file on the target, reconstructs the DML or DDL operations, and then applies them to the target. Learn to add a Replicat for Oracle Database, OCI Autonomous Databases, Oracle Exadata, and Amazon RDS for Oracle technologies.

Create a Checkpoint table

Before you add a Replicat, create a checkpoint table to ensure the Replicat can restart without recapturing reapplying transactions should a disruption occur.

To create a checkpoint table:
  1. In the OCI GoldenGate deployment console navigation menu, click Configuration.
  2. In the Administration Service tab, go to the Database tab.
  3. Click the database connect icon for the target database.
  4. Click Add Checkpoint (plus icon).
  5. For Checkpoint Table, enter the target schema name, and then click Submit.
  6. Reconnect to the target database.
