Choosing Local or Remote Display of the Installer

Language:

This section is relevant to users who plan to install the software using the graphical installer or command-line installer on Oracle Solaris 10 or Linux systems.

You can display the installer either locally or remotely while you are installing the Oracle Developer Studio software:

Local display. The source computer and the display computer are the same. The graphical installer window or command-line installer messages are displayed on the same computer that contains the downloaded files and runs the installer.
Remote display. The source computer and the display computer are different computers. The source computer contains the downloaded files and runs the installer. The display computer displays the graphical installer window or command-line installer messages. To install using a remote display, see How to Prepare for Installation Using a Remote Display.

How to Prepare for Installation Using a Remote Display

Type the following command on both the source computer and the display computer:
```
% hostname
```
The hostnames are used in subsequent steps.
Type the following command on the display computer:
```
% xhost + source-computer-name
```
Replace source-computer-name with the output of the hostname command entered on the source computer, which is the computer that contains the downloaded files.

The xhost command enables programs running on the source computer to send their displays to the X server on the display computer.
Log in to the source computer using ssh -X and become superuser (root)
You can use ssh with the -X option to forward the X display content back to the display computer. The source computer might not allow remotely logging in as root, so you might need to log in using your own username and become root after connecting to the source computer as shown below.
```
% ssh -X source-computer-name
Password: your password-on-source-computer
% su
Password: root-password-on-source-computer
```
On the source computer, set your DISPLAY variable to the display computer.
If you use the C shell, type:
```
# setenv DISPLAY display-computer-name:n.n
```
If you use the Bourne shell, type:
```
# DISPLAY=display-computer-name:n.n

# export DISPLAY
```
If you use the Korn shell, type:
```
# export DISPLAY=display-computer-name:n.n
```
Replace display-computer-name:n.n with the output of the hostname command entered on the display computer.

You can type echo $DISPLAY on the display computer to see the display number, such as :2.0
