You can configure an administrative agent, view or change stand-alone application server nodes registered to the administrative agent, and view or change job manager configurations for a registered node. An administrative agent provides a single interface to administer application servers in, development, unit test, or server farm environments, for example.
Install the WebSphere® Application Server product.
The administrative agent provides a single interface to administer multiple unfederated (stand-alone) application server nodes in, for example, development, unit test, or server farm environments. 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, view and change properties for nodes registered to the administrative agent, register and unregister application server nodes with job managers, and view and change job manager configurations for a registered node. A job manager allows you to asynchronously submit and administer jobs for a node registered to the administrative agent when the node is also registered to the job manager.
Depending on the tasks that you completed, you might have configured the administrative agent, registered and unregistered application server nodes with job managers, viewed or changed properties for a node registered to the administrative agent, or viewed and changed the job manager configuration for a registered node.
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.
You can register and unregister nodes with a job manager.
If you plan to change the system clock, stop all the
application servers, the node agent servers, the deployment manager
server, the administrative 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,
you must ensure the clocks on all systems that communicate with each
other and have WebSphere Application Server installed
are synchronized. Otherwise, you might experience errors, such as
security tokens no longer being valid.
