Using a Response File on Character Mode Consoles
When character mode consoles are used, Oracle recommends that you use the silent install,
which is available with 8.1.5 and 8.1.6. Most (if not all) UNIX systems have the X packages by default.
No additional installation is required.
In 8.1.5 and 8.1.6 versions of the Oracle Universal Installer, the Database Configuration Assistant
and Net8 Configuration Assistant require that the X software runs.
They all instantiate some GUI classes, but no GUI needs to be displayed if you running in silent mode.
An installation can be run from a console (non-X-Window system or a telnet/dial up session)
as long as the target system has X started.
