Resources

A resource is an instance of a resource type that is defined cluster wide. The resource type enables multiple instances of an application to be installed on the cluster. When you initialize a resource, the RGM assigns values to application-specific properties and the resource inherits any properties on the resource type level.

Data services utilize several types of resources. Applications such as Apache Web Server or Sun Java System Web Server utilize network addresses (logical hostnames and shared addresses) on which the applications depend. Application and network resources form a basic unit that is managed by the RGM.
