Every SCO OpenServer system should have at least one person in charge of system maintenance and operation. Such a person is called a ``system administrator''. It is the responsibility of system administrators to ensure the smooth operation of the system and to perform a wide variety of tasks that require special privileges.
Among other things, a system administrator is responsible for:
Depending on the size of the system and the number of users on it, system administration can be anything from a once-a-day task to a full-time job. Even if the system is small, the system administrator should consistently perform each required maintenance task, because sloppy maintenance can adversely affect system performance.
You can choose to have a single system administrator or divide the
tasks among several persons, each charged with a different area of
operation. You can even assign roles that are strictly limited to
one aspect of the system. See
``Assigning subsystem authorizations''
