Performing System Operation Tasks
Aborting a Session
From the console, you can stop, or abort, someone's session. Aborting a
session is an emergency measure. Usually, it is only one in a series of
steps taken to handle a specific situation. For example, aborting a
session is the last resort when you are troubleshooting a "hung" or
unresponsive terminal. And it is possible that you may need to abort
someone's session to shut down the computer, though this is less likely
since an orderly shutdown automatically aborts all jobs and sessions.
To display the user name
You need at least a user name and an account name or session number to
abort someone's session. If a user asks you to fix a terminal, the user
must give you a user name and account name.
To find the user and account name, enter:
SHOWJOB JOB=@S
You'll see something like the following information on your console:
________________________________________________________________________
| |
| |
| JOBNUM STATE IPRI JIN JLIST INTRODUCED JOB NAME |
| |
| |
| |
| #S25 EXEC 20 20 MON 1:26P OPERATOR.SYS |
| #S24 EXEC 22 22 SUN 12:27P BOB.CAROLL |
| #S23 EXEC 24 24 SUN 9:06A JULIE.JONES |
| #S64 EXEC 23 23 SUN 2:30P MGR.PAYROLL |
| |
________________________________________________________________________
To abort a session
To abort a session, use the session number that you found with the
SHOWJOB command. For example, to abort MGR.PAYROLL (who's session number
is #S64), enter:
ABORTJOB #S64
You should get a logoff message like the one below, although it may take
a few seconds.
________________________________________________________________________
| |
| |
| 14:45/#S64/32/LOGOFF ON LDEV #23 |
| |
________________________________________________________________________
14:45 is the time when you entered ABORTJOB, #S64 is the payroll
manager's session, and 23 is the hung terminal.
On the payroll manager's terminal, the computer prints the message
"SESSION ABORTED BY SYSTEM MANAGEMENT" and some other information.
To summarize the procedure, complete the five steps listed below to abort
a session on your computer when the need arises:
1. Enter SHOWJOB JOB=@S to find the session number.
2. Using that number, enter ABORTJOB #Snnn.
3. Look for a logoff message on the console.
4. Enter SHOWJOB #Snnn to make sure that there are "NO SUCH JOBS."
5. Complete steps 2 through 4 again if the job was not aborted on the
first attempt.
To stop all sessions in an emergency
Hopefully, you will never be forced to stop all sessions or shut down the
computer system without warning your users. In case it is necessary, you
use two commands to do so:
* Issue the LOGOFF command logs off all executing jobs and sessions
and prevent any further logons. This command also stops the
console session.
* Issue the SHUTDOWN command to do an implicit =LOGOFF as well as
perform an orderly shutdown of the rest of the system.
CAUTION Do not issue these commands now. Read for your information
only.
To immediately stop all jobs and sessions in an emergency:
1. At the console, hold down CTRL and press A.
2. When the "=" prompt appears, enter:
LOGOFF
Or enter:
SHUTDOWN
Since your session on the console is also stopped, you'll see the message
SESSION ABORTED BY SYSTEM MANAGEMENT on the console screen. (You receive
a logoff message about your session because, regardless of whether or not
you are using the console, it is still the computer's message center.)
NOTE Entering the SHUTDOWN command is the last in a series of steps
performed to shut down the computer system. Refer to chapter 10,
"Shutting Down the System" for information on system shutdown.
