In this type of recovery, a copy of the primary database is maintained on a separate server at all times. These systems are configured for disaster recovery purposes. If the primary database fails, the standby database is activated to operate as the new primary database. Automated Standby is an effective means for disaster recovery by providing a completely automated framework to maintain consistent copies of the primary database. This technology also provides an automated framework to switch over to the standby system in the event of a disaster or a corruption on the production site, or even during scheduled maintenance work.
