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. This topic describes how to view information about a node agent, stop and start the processing of a node agent, and stop and restart application servers on the node that is managed by the node agent.
Before you begin
Before you can manage a node agent, you must install the Network Deployment product.Why and when to perform this task
You can manage nodes 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.Steps for this task
IP verions:
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 that the node agent for the node must be processing to restart application servers on the node.
Result
Depending on the steps that you completed, you have viewed information about a node agent, stopped and started the processing of a node agent, and stopped and restarted application servers on the node that is managed by the node agent.What to do next
You can administer other aspects of the Network Deployment environment, such as the deployment manager, nodes, and cells.Related concepts
