SoftwareActivationLS requires the presence of an X Display, even though no output is generated during silent activation. An X display can be simulated by the use of Xvfb, a virtual X display. 1.) Make sure Xvfb is installed on your computer. It may be located in different locations based upon Unix flavor (try 'find / | grep Xvfb'). If not installed, add it to your system using your package management system (ie Redhat: 'yum install Xvfb') 2.) Start a virtual display server. The following command is typical for a basic service:'Xvfb :600 -screen 0 1280x1024x24 &'This example uses “600” as the display number. This can be changed as needed if a conflict arises.3.) Set the DISPLAY to the virtual display server:C Shell: setenv DISPLAY :600.0Bourne, Bash shell: DISPLAY=”:600.0”; export DISPLAY4.) Run the silent authorization procedure: './SoftwareAuthorizationLS -S -LIF <path to provisioning file>'5.) Stop the virtual display server by using the “ps” command to identify its process number and then using the kill command to stop it. On sun, the process name started by the Xvfb command is actually “XSun”. Linux: ps –ef | grep –i xvfbSolaris: ps –ef | grep –i xsunkill -9 <process_id_number>
