Oracle RAC in the cloud. Oracle Real Application Cluster (RAC) is a solution by Oracle to help customers achieve high throughputs by having many instances accessing one database storage (Shared-all architecture pattern).

Oracle Database can be configured in two basic ways: as a single instance (SI) database (non-cluster) or a Real Application Clusters (RAC) database. A single instance database has the Oracle software, database files, memory and processes all on one server. (link to database technical architecture diagram).

I will explain Architecture of Oracle RAC ( Real Application Cluster ) and What is the Oracle RAC in this article . In order to provide High Availability for Oracle database, Real Application Cluster (RAC) software was introduced in 2001 together with Oracle 9i.

Oracle Real Application Clusters One Node (Oracle RAC One Node) is a single instance of an Oracle Real Application Clusters (Oracle RAC) database that runs on one node in a cluster. This option adds to the flexibility that Oracle offers for database consolidation. You can consolidate many databases into one cluster with minimal
