Logging In to a Remote System Using X Window System

Use this procedure to run Oracle Universal Installer (OUI) by logging on to a remote system where the runtime setting prohibits logging in directly to a graphical user interface (GUI).

OUI is a graphical user interface (GUI) application. On servers where the runtime settings prevent GUI applications from running, you can redirect the GUI display to a client system connecting to the server.


If you log in as another user (for example, oracle or grid), then repeat this procedure for that user as well.

  1. Start an X Window System session. If you are using an X Window System terminal emulator from a PC or similar system, then you may need to configure security settings to permit remote hosts to display X applications on your local system.
  2. Enter a command using the following syntax to enable remote hosts to display X applications on the local X server:
    # xhost + RemoteHost

    RemoteHost is the fully qualified remote host name. For example:

    # xhost + somehost.example.com
    somehost.example.com being added to the access control list
  3. If you are not installing the software on the local system, then use the ssh command to connect to the system where you want to install the software:
    # ssh -Y  RemoteHost

    RemoteHost is the fully qualified remote host name. The -Y flag ("yes") enables remote X11 clients to have full access to the original X11 display. For example:

    # ssh -Y somehost.example.com
  4. If you are not logged in as the root user, and you are performing configuration steps that require root user privileges, then switch the user to root.


For more information about remote login using X Window System, refer to your X server documentation, or contact your X server vendor or system administrator. Depending on the X server software that you are using, you may have to complete the tasks in a different order.
