Node agents are administrative agents that represent a node to your system and manage the servers on that node. Node agents monitor application servers on a host system and route administrative requests to servers. A node agent is created automatically when a node is added to a cell.
Note: Both Internet Protocol Version 4 (IPv4) and Internet Protocol Version 6 (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 a node is added to a cell, the format in which the name is specified is based on the version of IP the node will be using. For details, see IP version considerations for cells.
Note: Although WebSphere Application Server supports IPv4 and IPv6, iSeries currently does not support IPv6.
Note that the node agent for the node must be processing (step 2) in order to restart application servers on the node.
