An administrative agent provides a single interface to administer multiple standalone application servers in environments such as development and unit test.
Make sure that the nodes that you want the administrative agent to manage have the same products as the administrative agent, and the products are at the same version levels on these node and the administrative agent. Starting with Version 7.0.0.13, this requirement is enforced because the administrative agent must have a matching environment in order to handle all of the administrative capabilities of the registered node. A node is not allowed to register with an administrative agent unless that node has an identical set of products and versions.
If you were previously running on Version 7.0.0.11 or earlier, and have an administrative agent with a managed node that has mismatched products or versions, when you apply Version 7.0.0.13 or later to the administrative agent, that administrative agent will not be able to start the subsystem for any mismatched nodes. You must update these nodes to have the same products and versions as the administrative agents, restart the servers on the node and then restart the administrative agent, before the administrative agent can resume managing these registered nodes
An administrative agent can monitor and control multiple application servers on one or more nodes. By using a single interface to administer your application servers, you reduce the overhead of running administrative services in every application server.
Use the WebSphere Customization Tools or the zpmt command and the customization jobs that they generate to configure an administrative agent on z/OS. The administrative agent must run on the same z/OS system as the application server nodes that it manages, and it must use the same SAF configuration group as the nodes to be managed.
An administrative agent can register any of the profiles that it manages with a job manager.
