What is a node? Is it a machine or cpu? Can I have more than one managed servers on one node? what is node manager? when was it introduced? What is the difference between admin server and node manager? Thanks. [ May 25, 2003: Message edited by: Jane Somerfield ]
Like Sameer said... A node is a single instance of WebLogic Server. A single machine can have multiple instances of WebLogic (and therefore nodes) running currently. A Node Manager is a Java program provided with WebLogic Server that enables you to start, shut down, restart, and monitor remote WebLogic Server instances. A Node Manager must be run on each physical machine running an instance of WebLogic Server that you would like to manage. See this link: Managing Server Availability with Node Manager.
