5.9 Step 8: Configure UNIX Machines

Using the Administration Console, add a new UNIX Machine for each machine which will host an Administration or Managed Server including the back-up machine and include the following settings:

5.10 Step 9: Assign Servers to Machines

Once all of the UNIX Machines are created, use the Administration Console to set the Machine property for each server, to ensure each server is associated with its corresponding UNIX Machine. See Assign server instances to machines in the Oracle WebLogic Server Administration Console Help.

5.11 Step 10: Start Managed Servers

In the Administration Console, start each Managed Server. See Start Managed Servers from the Administration Console in the Oracle WebLogic Server Administration Console Help. Check the server logs in the homendmgrclustdomainserversmanaged_ server_name logs directory of each Managed Server to ensure that the server has started with no errors.

5.12 Overriding the Default SSH Port

The default SSH port used by Node Manager is 22. You can override that setting in the following ways: ■ Set the Port= parameter in the ~.sshconfig file to set the default port for an individual user. ■ Set the Port= parameter in the etcssh_config file to set the default port across the entire system. ■ Start the Administration Server using the following system property: -Dweblogic.nodemanager.ShellCommand=ssh -o PasswordAuthentication=no -p P H Table 5–1 UNIX Machine Settings Property Value O.S.
