Node settings

Use this page to view or change the configuration or topology settings for either a managed node instance or an unmanaged node instance.

A managed node is a node with an Application Server and a node agent that belongs to a cell. An unmanaged node is a node defined in the cell topology that does not have a node agent running to manage the process. Unmanaged nodes are typically used to manage Web servers.

To view this administrative console page, click System Administration > Nodes > node.


Configuration tab


Specifies a logical name for the node. The name must be unique within the cell.

A node name usually is identical to the host name for the computer. However, you choose the node name. You can make the node name some name other than the host name.

Data type String

Both Internet Protocol V4 (IPv4) and Internet Protocol V6 (IPv6) are now supported by WebSphere Application Server, but there are restrictions that apply to using both IPv4 and IPv6 in the same cell. Note that when you add a node to a cell, the format in which you specify the name is based on the version of IP the node will be using.

Discovery Protocol

Specifies the protocol that the node follows to retrieve information from a network. The Discovery protocol setting is only valid for managed nodes.

Select from one of these protocol options:


User Datagram Protocol (UDP)


Transmission Control Protocol (TCP)

Data type String
Default TCP
Range Valid values are UDP or, TCP.

UDP is faster than TCP, but TCP is more reliable than UDP because UDP does not guarantee delivery of datagrams to the destination. Between these two protocols, the default of TCP is recommended.
