The Database Administrator's Operating System Account (25)

To perform many of the administrative duties for a database, you must be able to
execute operating system commands. Depending on the operating system on which
Oracle Database is running, you might need an operating system account or ID to gain
access to the operating system. If so, your operating system account might require
operating system privileges or access rights that other database users do not require
(for example, to perform Oracle Database software installation). Although you do not
need the Oracle Database files to be stored in your account, you should have access to
them.
