Oracle Clusterware uses agent programs (agents) to manage resources and includes the following built-in agents to protect applications:
appagent: This agent (appagent.exe in Windows) automatically protects resources of the generic_application resource type and any resources in previous versions of Oracle Clusterware of the application resource type.
Note:
Oracle recommends that you not use the deprecated application resource type, which is only provided to support pre-Oracle Clusterware 11g release 2 (11.2) resources.
scriptagent: Use this agent (scriptagent.exe in Windows) when using shell or batch scripts to protect an application. Both the cluster_resource and local_resource resource types are configured to use this agent, and any resources of these types automatically take advantage of this agent.
Additionally, you can create your own agents to manage your resources in any manner you want.
