Performing System Operation Tasks

Managing Session Activity 

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:

     HELLO OPERATOR.SYS 

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:
________________________________________________________________________
|                                                                      |
|                                                                      |

To determine the session limit 

To determine the maximum number of sessions (session limit) allowed on
the system, enter:

     LIMIT 

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:

     LIMIT ,0 

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:

     LIMIT 

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:

     LIMIT,nn 

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.

Enter:

     HELLO OPERATOR.SYS;HIPRI
