To achieve maximum PeopleSoft application availability, Oracle recommends deploying PeopleSoft on an Oracle Database MAA foundation that includes the following technologies:

• Oracle Real Application Clusters (Oracle RAC) and Oracle Clusterware.
• Oracle Active Data Guard, which provides active database replication of the primary site to the secondary site.
• Oracle Flashback Database
• Oracle Automatic Storage Management (Oracle ASM), with high redundancy disk groups
• Oracle Recovery Manager (RMAN) and Oracle Secure Backup

On the primary site, Oracle RAC provides fault tolerant databases and enables server scale out. Online upgrade provides hardware and software updates. Flashback on the primary site can be used to reinstate the failed primary database post failover to a standby site.

On the secondary site, Oracle ASM provides fault tolerant storage with storage scale out. Flashback on the secondary site provides rewind on error.
