15 Implementing Additional High Availability Strategies

Besides replication, other high availability strategies can be used with Recovery Appliance to increase protection against data loss in certain scenarios.

The Oracle Maximum Availability Architecture (MAA) best practice to protect the appliance against site disasters and system outages is to implement a disaster recovery strategy using Recovery Appliance replication. With a replica appliance, protected database backup, redo, and restore operations continue uninterrupted, preserving complete data protection.

If your organization does not have a disaster recovery strategy or if you would like to add local system high availability to your existing disaster recovery strategy, you can use the Backup and Redo Failover feature of Recovery Appliance.

Another component of a high availability (HA) and disaster recovery solution is Oracle Data Guard. Oracle Data Guard minimizes service interruption and resulting data loss by maintaining a synchronized standby database for the protected database.
