Column Display
You can show fewer or additional data points on this page by expanding Customize this table and modifying the Column Display list. Each data point displays in its own table column.
The following table lists all of the data points that you can display in columns on this page.
Name Description Machine The WebLogic Server host computer (machine) on which this server is meant to run.
If you want to use Node Manager to start this server, you must assign the server to a machine and you must configure the machine for Node Manager.
You cannot change this value if a server instance is already running.
MBean Attribute:
ServerMBean.MachineChanges take effect after you redeploy the module or restart the server.
Server An alphanumeric name for this server instance. (Spaces are not valid.)
The name must be unique for all configuration objects in the domain. Within a domain, each server, machine, cluster, JDBC connection pool, virtual host, and any other resource type must be named uniquely and must not use the same name as the domain.
The server name is not used as part of the URL for applications that are deployed on the server. It is for your identification purposes only. The server name displays in the Administration Console, and if you use WebLogic Server command-line utilities or APIs, you use this name to identify the server.
After you have created a server, you cannot change its name. Instead, clone the server and provide a new name for the clone.
MBean Attribute:
ServerMBean.NameChanges take effect after you redeploy the module or restart the server.
Application Name The name of the Enterprise application.
