In a Tivoli environment, any managed resource on which the Tivoli Management Framework is installed.
Nodes can be managed or unmanaged. An unmanaged node does not have a node agent or administrative agent to manage its servers, whereas a managed node does. Both application servers and supported web servers can be on unmanaged or managed nodes.
A stand-alone application server is an unmanaged node. The application server node becomes a managed node when it is either federated into a cell or registered with an administrative agent.
Example of usage – “When you create a managed node by federating the application server node into a deployment manager cell, a node agent is automatically created. The node agent process manages the application server configurations and servers on the node.”
