Silent installation is a non-interactive mode that enables you to run the installer on multiple hosts using an installer configuration file called a state file. The state file is created when the --savestate option is used with the setup command. The state file is saved in the installation directory (/sun/webserver7 by default on UNIX, C:\Program Files\Sun\WebServer7 on Windows). The default name of the file is statefile, but the file name can be changed if desired.
To activate the silent mode, create the state file and then start the installation program using the --silent option (./setup --silent state_file). After the silent mode is activated, installation takes place without additional input. For more information about creating a state file and installing the Web Server using silent installation, see Installing in Silent Mode.
