The Managed Servers in a production WebLogic Server environment are often
distributed across multiple machines and geographic locations.
Node Manager is a stand-alone Java utility, provided with WebLogic Server, that
allows you to perform common operations tasks for a Managed Server, regardless of
its location with respect to its Administration Server. If you run Node Manager on a
