Describe The Oracle Real Application Clusters Architecture?

1.	Describe The Oracle Real Application Clusters Architecture?
Answer» Oracle RAC consists of a database that is represented in a clustered manner in the architecture. The cluster is the COLLECTION or pool of independent servers that make up one single system. Cluster architecture provides more flexibility to manage and follow a modular incremental APPROACH to improve the FAULT errors and PROVIDE an incremental system. This architecture provides the maximum security in terms of ensuring high AVAILABILITY of the resources to the users. It provides the resources on demand and provides hardware architecture such that a single point of failure is being removed. The architecture provides the decoupling of the Oracle instance like the process and memory that are running on the server from the Oracle database.
