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.

Note:

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

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.
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
```
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
```
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.

Note:

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.
