Amazon RDS for Oracle now supports cross-Region replicas with additional storage volumes. With additional storage volumes, customers can add up to three storage volumes, each with up to 64 TiB, in addition to the primary storage volume for their database instance. As a result, customers get flexibility to add or remove storage with evolving workload demands, without incurring application downtime, and set up their database instance with up to 256 TiB storage. Now, with support for cross-Region replicas, customers that set up database instances with cross-Region replicas for business-critical applications also get the benefit of using additional storage volumes for storage flexibility.
When you create a cross-Region replica for a database instance that is set up with additional storage volumes, Amazon RDS for Oracle automatically configures the same storage layout on the replica. Subsequently, you can apply changes to additional storage volumes on the primary instance and the replica using the AWS Management Console, AWS CLI, or AWS SDK. In disaster recovery situations, you can promote a cross-Region replica to serve as the new standalone database, or execute a switchover to reverse roles between the primary database and the replica to meet low recovery point objective (RPO) and recovery time objective (RTO) for business critical applications.
You will need an Oracle Database Enterprise Edition (EE) license to use replicas in mounted mode, and an additional Oracle Active Data Guard license to use replicas in read-only mode. We recommend consulting your legal team or licensing expert to verify Oracle license requirements for your specific use case. Amazon RDS for Oracle cross-Region replicas with additional storage volumes is available in all AWS Regions including the AWS GovCloud (US) Regions.
