Uninstalling When Previous Releases of Sun Studio Software Are Installed

I f you installed the Sun Studio 12 Update 1 software on a system that has previous Sun Studio software installations, then only the Sun Studio 12 Update 1 is removed when you run the uninstaller. The uninstaller removes all of the installed product components.

Choosing Local Display or Remote Display of the Uninstaller

You can display an uninstaller either locally or remotely while you are uninstalling Sun Studio 12 Update 1 software.

Preparing for Uninstallation Using a Remote Display

1. On the display computer, enable client access to the X server by typing the following on the command line:

   xhost + source-computer-name

   Replace source-computer-name with the output of the /usr/bin/hostname command entered on the source computer, which is the computer that contains the product CD-ROM or downloaded files.

2. Log in to the source computer and become a superuser (root).

   rlogin source-computer-name -l rootname Password: root-password

3. On the source computer, set the display to the monitor that is attached 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 with the output of the /usr/bin/hostname entered on the display computer.

Uninstalling the Software

You can uninstall all of the installed components of the Sun Studio 12 Update 1 software using the graphical user interface uninstaller or the non-GUI uninstaller.
