In a WebLogic domain, the machine definitions identify physical units of hardware and are associated with the WebLogic Server instances or system components (such as OHS servers) that they host.
Use this screen to add or delete machines, or to modify the settings for an existing machine. Each machine has the following configuration settings.
Select the Machine tab (for Windows) or the UNIX Machine tab (for UNIX).
| Column | Description |
|---|---|
|
Name |
Enter a valid machine name. The machine name is used to identify the machine within the WebLogic domain; it does not have to match the network name for the machine. The name must be unique among all component names within the domain. |
|
Node Manager Listen Address |
Select a value from the drop-down list for the listen address used by Node Manager to listen for connection requests. By default, the IP addresses defined for the local system and localhost are shown in the drop-down list. The default value is localhost. If you specify an IP address for a machine that hosts the Administration Server and you need to access the WebLogic Server Node Manager, you must disable host name verification. More |
|
Node Manager Listen Port |
Enter a valid value for the listen port used by Node Manager to listen for connection requests. The valid Node Manager listen port range is from 1 to 65535. The default value is 5556. |
|
Post bind GID enabled |
(UNIX machines only) Select this check box to enable a server running on this machine to bind to a UNIX group ID (GID) after it finishes all privileged startup actions. By default, this check box is not selected. |
|
Post bind GID |
(UNIX machines only) Enter the UNIX group ID (GID) under which a server on this machine will run after it finishes all privileged startup actions. Otherwise, the server continues to run under the group from which it was started. For this setting to take effect, you must select the Post bind GID enabled check box. |
|
Post bind UID enabled |
(UNIX machines only) Select this check box to enable a server running on this machine to bind to a UNIX user ID (UID) after it finishes all privileged startup actions. By default, this check box is not selected. |
|
Post bind UID |
(UNIX machines only) Enter the UNIX user ID (UID) under which a server on this machine will run after it finishes all privileged startup actions. Otherwise, the server continues to run under the account from which it was started. For this setting to take effect, you must select the Post bind UID enabled check box. |
You might want to create machine definitions in situations such as the following:
The Administration Server uses the machine definition, with the Node Manager application, to start remote servers.
WebLogic Server or other system components such as OHS use configured machine names when determining the server in a cluster that is best able to handle certain tasks, such as HTTP session replication. Those tasks are then delegated to the identified server.
|
Note: You must configure machines for each product installation that runs a Node Manager process. The machine configuration must include values for the listen address and port number parameters. |
Click Add to add a new machine. The default name for a new machine is new_[Unix]Machine_n, where n starts at 1 and increments by 1 for each machine that you add.
Click Delete to delete an existing machine.
