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 Server, 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.
