Oracle RAC, introduced with Oracle9i, is the successor to Oracle Parallel Server (OPS). RAC allows multiple instances to access the same database (storage) simultaneously. It provides fault tolerance, load balancing, and performance benefits by allowing the system to scale out, and at the same time because all nodes access the same database the failure of one instance will not cause the loss of access to the database.
