Grid Computing

Grid computing turns computing into a utility, where users don't care where the data resides, or what computer processes a request. 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. Automatic Storage Management provides the infrastructure for a storage grid. Oracle Enterprise Manager Grid Control provides you with holistic management of your grid.

Supporting Documentation

Documentation on this page describes how to manage Oracle Clusterware and Oracle Real Applications Clusters deployments.

Oracle Real Application Clusters

Oracle Real Application Clusters enables a single database to run across multiple clustered nodes in a grid, pooling the processing resources of several standard machines.

Oracle Clusterware

Oracle Clusterware is a portable cluster software that allows clustering of single servers so that they cooperate as a single system. Oracle Clusterware also provides the required infrastructure for Oracle Real Application Clusters (RAC). Oracle Clusterware also enables the protection of any Oracle application or any other kind of application within a cluster.

Oracle Automatic Storage Management

Oracle Automatic Storage Management (ASM) provides a virtualization layer between the database and storage. It treats multiple disks as a single disk group, and lets you dynamically add or remove disks while keeping databases online.
