Sun Java System Web Server 7.0 Update 4 Administrator's Guide


Instance refers to the environment of a web server daemon on a given node, including its configuration, log files and other runtime artifacts such as lock databases, caches and temporary files.

A node is a network resource, such as a server or a host. In a typical data center, a network of nodes is called a server farm. This section discusses how nodes can be configured using the administration console GUI.

You can deploy one or many instances to a node. The same instance can be deployed to multiple nodes and can be part of different clusters.

For management purposes, an instance can be started, stopped, restarted or dynamically re-configured.
