Note: Providing a UNIX Group Name If you are installing a product on a UNIX system, the Installer will also prompt you to provide the name of the group which should own the base directory. You must choose a UNIX group name which will have permissions to update, install, and deinstall Oracle software. Members of this group must have write permissions to the base directory chosen. Only users who belong to this group are able to install or deinstall software on this machine.
