A machine is the logical
representation of the computer that hosts one or more WebLogic Server
instances. Each managed server must be assigned to a machine.
To create and configure
If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).

The Machines table displays in the right pane showing all the
machines defined in the domain.
Enter a name for the new machine in the

This name is used to identify the machine within the WebLogic
Server domain. This name does not have to correspond to the
machine's network name.
Select UNIX in the Machine OS field.
The new machine is displayed in the Machines table.

To specify a non-privileged user account under which the
server instance runs, place a check mark in the Enable
Post-bind UID field and enter the user ID in the

The user ID that you enter must have read, write, and execute
privileges within the BEA Home directory, the WebLogic Server
product directory tree, and your domain directory.
The default value of the Post-Bind UID
field, nobody, is a standard UNIX account
that provides the least possible privileges. While the
nobody account is acceptable for use in a
development environment, in a production environment, BEA
recommends that you create an operating-system user account
specifically for running instances of WebLogic Server. See
"Securing the WebLogic Server Host."
To specify a non-privileged group instead of (or in addition
to) providing a user ID, place a check mark in the

To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Not all changes take effect immediately—some require a restart (see Use the Change Center).
The new machine entry now specifies the attributes required to
connect to the Node Manager process running on the machine, as well as
identify which WebLogic Server instances reside on the machine. For
