About agents

An agent is defined as a process that starts, stops, and monitors all configured

resources of a type, and reports their status to Veritas Cluster Server (VCS). Agents

have both entry points and attributes. Entry points are also known as agent

functions and are referred to as "agent functions" throughout the document.

Attributes contain data about the agent. An attribute has a definition and a value.

You change attribute values to configure resources, which are defined as the

individual components that work together to provide application services to the

public network. For example, a resource may be a physical component such as a

disk or a network interface card, a software component such as Oracle or a Web

server, or a configuration component such as an IP address or mounted file system.
