Oracle Real Application Clusters (RAC) is an option to the award-winning Oracle Database Enterprise Edition.

Oracle RAC is a key component of Oracle's private cloud architecture. Oracle RAC support is included in the Oracle Database Standard Edition for higher levels of system uptime.

Oracle RAC One Node is a single instance of an Oracle RAC enabled database running on one node in a cluster and a low cost entry to flexible database consolidation. Oracle RAC One Node as an option to the award-winning Oracle Database Enterprise Edition adds to the flexibility that Oracle offers for database consolidation while reducing management overhead by providing a standard deployment for Oracle Databases in the enterprise.
