Shutting Down the System

Send a TELL message to your users 15 minutes before the shutdown. Enter:

   TELL @S;SHUTDOWN IN 15 MINUTES.  PLEASE LOG OFF.

This message reaches all active terminals, except those in quiet mode. One way to inform all users is to repeat the TELL message a few minutes later with an extra note. Enter:

   TELL @S;SHUTDOWN IN 10 MINUTES.

   PLEASE TELL YOUR QUIET NEIGHBORS.

If you cannot conveniently contact the quiet users, you can send them a WARN message. For example:

   WARN #S123;SHUTDOWN IN 10 MINUTES

Prevent anyone from starting a new job, session, or printing new reports.

In addition to asking users to quit using the computer, you also must make sure that nobody starts any new work. About 10 minutes before the shutdown, enter:

   LIMIT 0,0 Return



   JOBFENCE 14 Return

The command LIMIT 0,0 limits the number of concurrently running jobs and sessions. The two parameters, in this case, 0,0 define the allowed number of jobs and sessions, respectively.

The command JOBFENCE 14 defines the minimum input priority a job or session must have to execute. The parameter 14 raises the jobfence to the highest level.

Close any open communication lines.
