Administering stand-alone nodes using the administrative agent

You can configure an administrative agent and view or change stand-alone application server nodes registered to the administrative agent. An administrative agent provides a single interface to administer application servers in, for example, development, unit test, or server farm environments.

Before you begin

Install the WebSphere® Application Server product.

About this task

The administrative agent provides a single interface to administer multiple stand-alone application server nodes in, development, unit test, or server farm environments, for example. By using a single interface to administer your application servers, you reduce the overhead of running administrative services in every application server.

You can use the administrative console of the administrative agent to configure the administrative agent and view and change properties for nodes registered to the administrative agent.

• Set up the administrative agent environment.

  Create an administrative agent profile and one or more stand-alone application server profiles, called nodes, on the same computer and then register the node profiles with the administrative agent.

• Start and stop the administrative agent as needed.
• View and change properties for the administrative agent.
  1. Click System Administration > Administrative agent from the navigation of the administrative agent administrative console.
     • Optionally view the administrative agent properties on the Configuration tab and the Runtime tab.
     • Optionally select Start components as needed on the Configuration tab. Click Apply, and then click OK.

       Selecting the setting allows administrative agent components to start dynamically as needed for applications.

• View and change properties for a node registered to the administrative agent.
  1. Click System Administration > Administrative agent > Nodes.
     • You can view the nodes registered to the administrative agent.
  2. Click System Administration > Administrative agent > Nodes > node_name.

     The page is read-only. To change properties for the node, click the links under Additional Properties.

• Unregister a stand-alone application server node from the administrative agent.

  Unregister nodes if you no longer need the node in the administrative agent environment or if you intend to delete the stand-alone application server node profile. Run the deregisterNode command to unregister a node.

Results

Depending on the steps that you completed, you might have configured the administrative agent, or viewed or changed properties for a node registered to the administrative agent.

What to do next

You can continue to administer registered nodes from the administrative agent. You can further configure the administrative agent using the links on the configuration tab of the administrative agent panel. You can register more nodes with the administrative agent using the registerNode command. You can unregister nodes from the administrative agent using the deregisterNode command.
