Manage node agents

Node agents are admin 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. Before you can manage a node agent, install the WAS ND.

If you plan to change the system clock, stop all the application servers, the node agent servers, the dmgr server, the admin agent server, and the job manager server first. After you stop the servers, change the system clock, and then restart the servers. If you change the system clock on one system, ensure the clocks on all systems that communicate with each other and have WAS installed are synchronized. Otherwise, you might experience errors, such as security tokens no longer being valid.

A node agent is a server that is created automatically when a node is added to a cell. A node agent runs on every host computer system that participates in the WAS ND. We can view information about a node agent, stop and start the processing of a node agent, stop and restart application servers on the node that is managed by the node agent, and so on.

A node agent is purely an admin agent and is not involved in application serving functions. A node agent also hosts other important administrative functions, such as file transfer services, configuration synchronization, and performance monitoring.

We can manage nodes through the wsadmin scripting tool, through the Java API, or through the administrative console. To manage nodes on an application server through the administrative console.



Depending on the steps that you completed, we 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

We can administer other aspects of the WAS ND environment, such as the dmgr, nodes, and cells.
