<a name="oracle-read-replicas"></a>

To configure replication between Oracle DB instances, you can create replica databases. For an overview of Amazon RDS read replicas, see [Overview of Amazon RDS read replicasOverview](USER_ReadRepl.md#USER_ReadRepl.Overview). For a summary of the differences between Oracle replicas and other DB engines, see [Differences between read replicas for DB engines](USER_ReadRepl.Overview.Differences.md).
