Oracle Real Application Clusters One Node - license - 1 processor

Oracle Real Application Clusters One Node (Oracle RAC One Node) is a one-node version of Oracle Real Application Clusters which enables customers to standardize on a single deployment model for all their database needs. It offers far greater benefits than traditional server virtualization to single instance databases running on a hardware cluster. You can consolidate multiple databases into a single cluster with minimal overhead while providing the high availability benefits of failover protection, rolling upgrades, and more.

Oracle Real Application Clusters One Node improves upon many of the benefits of server virtualization and extends them to databases running in physical server environments. In addition it allows customers to virtualize database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption.
