Clustering

Clustering relieves users from concerns about where data resides and which computer processes their requests. Users request information or computation and have it delivered - as much as they want, whenever they want. For the DBA, the grid is about resource allocation, information sharing, and high availability. Oracle Database with Real Application Clusters and Oracle Clusterware provide the infrastructure for your database grid. Oracle Automatic Storage Management (Oracle ASM) provides the infrastructure for a storage grid. Oracle Enterprise Manager Grid Control provides you with holistic management of your grid.
