Configuring Machines

As explained in Chapter 2, you'll need to create a machine definition if you want the Node Manager to start remote Managed Servers. In addition, the concept of a machine helps WebLogic Server determine the best servers in a cluster to handle various domain-wide tasks. You must configure machines for each server where you're running a Node Manager process. Chapter 2 also showed you how to create a machine definition in the Configuration Wizard, in which you select the Machine tab (Windows) and click Add to add a machine definition. You specify a machine name, as well as the Node Manager listen address (the default is localhost) and listen port (the default is 5556). On UNIX servers, there are additional configuration items relating to the UNIX GID (UNIX group ID). Click Next after you select the settings.
