Overview

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.

 

Procedure

1. View information about a node agent. Use the Node Agents page. Click...

   System Administration | Node Agents

   ...in the console navigation tree. To view additional information about a particular node agent or to further configure a node agent, click on the node agent's name under Name.

   Note: 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 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.

2. Stop and then restart the processing of a node agent.

   On the Node Agents page, place a check mark in the check box beside the node agent you want to restart, then click Restart. It is important to keep a node agent running because a node agent must be running in order for application servers on the node managed by the node agent to run.

3. Stop and then restart all application servers on the node managed by the node agent.

   On the Node Agents page, place a check mark in the check box beside the node agent that manages the node whose servers you want to restart, then click Restart all Servers on Node.

   Note that the node agent for the node must be processing (step 2) in order to restart application servers on the node.

4. Stop the processing of a node agent.

   On the Node Agents page, place a check mark in the check box beside the node agent you want to stop processing, then click Stop.
