# Machines: Configuration: Node Manager

Configuration Options Related Tasks Related Topics

This page allows you to define the Node Manager configuration for this machine. To control a Managed Server from the console, Node Manager must be configured and running on the machine where the Managed Servers are installed.

The settings defined on this page are used to configure communication between the current domain and Node Manager instances that control Managed Servers. This page does not control the cofiguration of the Node Manager instances.

Node Manager is a Java program provided with WebLogic Server that enables you to start, shut down, restart, and monitor the health of Managed Servers. Node Manager allows you to control Managed Servers from a remote machine, and is required if you wish to use the Administration Console to control Managed Servers remotely. To utilize Node Manager capabilities for a Managed Server, Node Manager must run on the physical machine that hosts the Managed Server. This page allows you to define the Node Manager configuration for this machine.
