What is Clustering?
Clustering is the grouping of individual computers in such a way that they can act as a single computer system. These combined resources can then be presented to applications as a single system. One benefit of a cluster is that the application does not need to be cluster “aware”, and requires no special coding to take advantage of most cluster related services.
Oracle clustering is a shared everything architecture that involves sharing of storage by the systems of the cluster.
Oracle RAC:
Oracle RAC stands for Real Application Cluster. It was introduced by Oracle with 9i release. Latest version is 11gR2.
Oracle RAC is a cluster database with a shared cache architecture that overcomes the limitations of traditional shared-nothing and shared-disk approaches to provide highly scalable and available database solutions for all your business applications. Oracle RAC is a key component of Oracle’s private cloud architecture.
