A session is a two-way dialog between you and the computer. The computer
interprets and follows the commands that you enter at the keyboard, if it
can. If it cannot, it uses an error message to tell you that something is
wrong. Computer sessions are unique because you attempt to get the computer
to perform a specific task.
To start a computer session |

To start a computer session, enter your logon command at the MPE XL prompt:
The computer responds by displaying the version number of the operating
system, the day, date, and time, and a welcome message, if one exists.
When the system prompt (:) appears, the session has begun. For example:
USER: #S22,OPERATOR.SYS,PUB (NOT IN BREAK)

To determine the session limit |
|
To determine the maximum number of sessions (session limit) allowed on
the system, enter:
You will see both the job and session limit for your computer.
To set the session limits |
|
You can set the session limit to any number up to the maximum limit
configured for your computer. Most of the time, you
either leave it alone or change it to zero. This prevents all but a few
special users from starting new sessions on the computer, regardless of
how many are currently using it.
You can only issue the LIMIT command from the console unless it
is allowed to a user.
To lower the session limit to 0, enter:
Be sure to enter the comma before the 0. Otherwise, you change the job
limit, not the session limit.
To check the new session limit, enter:
No one already using the computer is affected by the low session limit.
But anyone who tries to log on (except users assigned OP or SM capability)
will see the message CAN'T INITIATE NEW SESSIONS NOW.
To reset the session limit |
|
To reset the session limit to its normal value, enter:
Replace nn with your original session limit.
To bypass the session limit |
|
If you have OP or SM capability, you can start a new session on the computer
even when the session limit is set to 0. To do so,
you add ;HIPRI to the end of your computer identity
to tell the computer to bypass whatever restrictions are in effect.
This is known as a high priority logon.
