The recommended Oracle GoldenGate configuration, when supported by the Oracle version, is to use one Extract on an Oracle source and one parallel Replicat per source database on an Oracle target.

One integrated Replicat configuration supports all Oracle data types either through the inbound server or by switching to direct apply when necessary, and it preserves source transaction integrity. You can adjust the parallelism settings to the desired apply performance level as needed.

Each Replicat group must process objects that are suited to the processing mode, based on table data types and attributes. No objects in one Replicat can have DML or DDL dependencies on objects in the other Replicat.

If the target database is an Oracle version that does not support integrated Replicat, or if it is a non-Oracle database, you can use a coordinated or parallel Replicat configuration.
