CE

Oracle Clusterware manages applications when they are registered as resources with Oracle Clusterware. Oracle Clusterware has access to application-specific primitives that have the ability to start, stop, and monitor a specific resource. Oracle Clusterware runs all resource-specific commands through an entity called an agent. Note: When initializing the agent framework, if any of the mandatory entry points are not provided, then the agent framework invokes a script pointed to by the ACTION_SCRIPT resource attribute.
