1. Remove all users from the system.
If your system is not currently in use, skip to step 2.
a. Log on at the system console as MANAGER.SYS. Enter:
:HELLO MANAGER[/userpass].SYS[/acctpass]
b. Tell users of the approaching shutdown.
Notice that entering ISL makes the system inaccessible to users. Use the TELL command to alert
users (except those in quiet mode) to the impending system shutdown. Ten minutes beforehand, ask
users to log off. Enter:
:TELL @S;SYSTEM SHUTDOWN IN 10 MIN. PLEASE LOG OFF.
c. Prevent new system activity. Enter:
:LIMIT 0,0
:JOBFENCE 14
The command LIMIT 0,0 limits the number of concurrently running jobs and sessions. The two
parameters x, x define the allowed number of jobs and sessions, respectively.
The command JOBFENCE defines the minimum input priority that a job or session must have to
execute. The parameter, 14, raises the jobfence to the highest level.
d. Warn users five minutes prior to the system shutdown to end their sessions. Use the WARN command
to alert all sessions (including those in quiet mode) to the shutdown. Enter:
:WARN @S; SYSTEM LOSS IN 5 MIN. PLEASE LOG OFF.
e. Locate all jobs and sessions still in progress or scheduled. Enter:
:SHOWJOB JOB=@J
:SHOWJOB JOB=@S
The command SHOWJOB displays the status information about jobs or sessions.
f. Abort jobs and sessions still executing. Enter:
:ABORTJOB #Jnnn (#Jnnn is the number for each job)
:ABORTJOB #Snnn (#Snnn is the number for each session)
2. Reset the system. Enter:
:CTRL A
=SHUTDOWN
3. Once the system issues the final shutdown message:
Shutdown of operating system complete. (Shut 6)
Enter:
:CTRL B

Reset messages appear at the console while the system runs its self-test.
