-   A cluster is a set of 2 or more machines (nodes) that share or coordinate resources to perform the same task.

        - A RAC database is 2 or more instances running on a set of clustered nodes, with all instances accessing a shared set of database files.

-         Depending on the O/S platform, a RAC database may be deployed on a cluster that uses vendor cluster ware plus Oracle's own cluster ware (Cluster Ready Services), or on a cluster that solely uses Oracle's own cluster ware.
