The system administrator and group header can set terminal login privileges, number of logins, and connect-time limits, which are enforced hierarchically by Solaris Resource Manager. As a user approaches a connect-time limit, warning messages are sent to the user's terminal. When the limit is reached, the user is notified, then forcibly logged out after a short grace period.
Solaris Resource Manager progressively decays past usage of connect-time so that only the most recent usage is significant. The system administrator sets a half-life parameter that controls the rate of decay. A long half-life favors even usage, while a short half-life favors interactive users.
