Select a Replicat Type for the Deployment

Replicat is responsible for applying trail data to the target database. Although you can choose from different types of Replicat modes, Oracle recommends that you use the parallel nonintegrated Replicat, unless a specific feature requires a different type of Replicat. Parallel Replicat is available for both Oracle and non-Oracle databases.
