Adding, managing, and removing nodes

You can add a node, select the discovery protocol for a node, define a custom property for a node, stop servers on a node, and remove a node.

Before you begin

A node is a grouping of managed or unmanaged servers. You can add both managed and unmanaged nodes to the WebSphere® Application Server topology. If you add a new node for an existing WebSphere Application Server to the network deployment cell, you add a managed node. If you create a new node in the topology for managing web servers or servers other than WebSphere Application Servers, you add an unmanaged node.

You can recover an existing managed node of a deployment manager cell. One of the options to add a managed node enables you to quickly recover a damaged node. The option is similar to the -asExistingNode parameter of the addNode command.

To view information about nodes and managed nodes, use the Nodes page. To access the Nodes page, click System administration > Nodes in the administrative console navigation tree.

About this task

You can manage nodes on an application server through the wsadmin scripting tool, through the Java application programming interfaces (APIs), or through the administrative console. Perform the following tasks to manage nodes on an application server through the administrative console.

[Windows] Restriction: The addNode function in the administrative console might fail on non-English, single-byte Windows operating systems when there are non-ASCII characters in the profile name, cell name, or node name. This problem is caused by a code page issue on Windows operating systems. To work around this problem, run the addNode command from the command line rather than from the administrative console on non-English, single-byte Windows operating systems if there are non-ASCII characters in the profile name, cell name, or node name.

Procedure

What to do next

If you changed a node configuration, examine the configuration changes.
