A shared-disk architecture (SD) is a distributed computing architecture in which the nodes share same disk devices but each node has its own private memory. The disks have active nodes which all share memory in case of any failures. In this architecture the disks are accessible from all the cluster nodes. Webbarchitecture is a clustered database architecture running on a shared-disk cluster, a form of cluster in which all nodes have direct access to all disks. RAC is so called since it transparently allows any database application to run on a cluster without requiring any application changes. RAC allows for improvements in application performance since
