Use this page to view information about node agents. Node agents are administrative agents that monitor application servers on a host system and route administrative requests to servers. A node agent is the running server that represents a node in a Network Deployment environment.

A node name usually is identical to the host name for the computer. That is, a node usually corresponds to a physical computer system with a distinct IP host address.
However, the node name is a purely logical name for a group of servers. You can name the node anything you please. The node name does not have to be the host name.
Note that if the status of servers such application servers is Unavailable, the node agent is not running in the servers' node and you must restart the node agent before you can start the servers.
