Federated or managed environment

If you have several environments with several applications on several machines, you will by default have several administrative consoles. To simplify management, you may want to use a single administrative console. To do this you federate to a deployment manager. The federation process aggregates the configuration from all of the nodes to a single point of management at the deployment manager. The deployment manager provides the ability to manage multiple servers from a single point. The deployment manager is responsible for distributing the configuration across all of the machines that it manages. To do this there is a network of servers that communicate with each other. They share information about the state of the configuration on each node. This grouping of servers is called a cell. The cell encompasses the DMGR and all of the nodes and processes that it is managing.

The DMGR contains the master configuration. You must make changes in the master configuration by connecting to the deployment manager.
