Node Manager Runs on Machines that Host Managed
Servers
To take advantage of Node Manager capabilities, you must run a Node Manager
process on each machine that hosts Managed Servers. You can manage multiple
Managed Servers on a single machine with one Node Manager process—in Figure 3-1,
the two Managed Servers on Machine C can be controlled by a single Node Manager
process.
You cannot use Node Manager to start or stop an Administration Server. In a
production environment, there is no need to run Node Manager on a machine that runs
an Administration Server, unless that machine also runs Managed Servers. In a
