Sending Warning Messages
About 10 minutes before you plan to begin the backup, use the WARN
command to send a message to all users asking them to log off the system.
Unlike the TELL command, the WARN command interrupts users working in
QUIET mode so that you can be sure they know about the impending backup.
Enter the command below, substituting the time you intend to begin the
backup for hh:mm.
:WARN @S; BACKUP WILL BEGIN AT hh:mm. PLEASE LOG OFF
Now that everyone has been warned, find out who is still using the
system. Enter:
:SHOWJOB JOB=@S
The system responds by listing all sessions. Since you have already told
users about the backup once, and warned them again, most users should
have ended their sessions. Periodically use the SHOWJOB command to see
who is still logged on to the system.
NOTE For an online backup, send these messages to users. However, you
could change the text of the message to let users know that they
can log on after a certain amount of time has passed. The amount
of time users have to remain logged off the system depends on how
much data is being stored. It can range anywhere from 1 to 30
minutes.
For a 7x24 true-online backup, you can send a warning message to
users notifying them that the true-online backup is about to begin.
However, you do not have to tell them to log off.
