Oracle RAC is the abbreviated version of Oracle Real Application Clusters. Based on ORACLE  DB, this clustered version is a high availability comprehensive stack that can be used as foundation of database cloud system. ORACLE-RAC can be used for agility, high availability, & scalability for an application. Flexible workload management is one of the advantages of using Oracle RAC.
