Including Shutdown Information in the Welcome Message
Including Shutdown Information in the Welcome Message
Include shutdown information in the welcome message. Remember to include information
about the time of the shutdown and whom a user should contact with questions. Enter:
:WELCOME
#
Return
This erases the present WELCOME message. Enter for a second time:
:WELCOME
#
When the pound sign prompt (#) appears, enter the message line by line, terminating each
line with Return. Enter Return at the prompt to terminate the WELCOME message facility.
When users log on to the computer, the message notifies them of the impending shutdown.
They can then plan their schedules accordingly.
Telling Users about the Shutdown
Use the TELL command to alert users to the upcoming shutdown approximately 15
minutes beforehand. Enter:
:TELL @S;Shutdown in 15 minutes. Please log off.
This message reaches all active terminals, except those in quiet mode.
Limiting System Use
Use the LIMIT and JOBFENCE commands to prevent any new users from logging on or any
scheduled jobs from starting. Enter:
:LIMIT 0,0
:JOBFENCE 14
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 that a job or session must
have to execute. The parameter 14 raises the jobfence to the highest level.
Shutting the Spool Queues and Handling the Remaining Reports
To verify that the printer is available, to shut down spool queues, and to begin removing
backlogged reports, complete the following steps:
1. Verify the printer is active. Enter:
:SHOWDEV nn
( nn is your printer’s ldev number.)
