How system shutdown is carried out |
 |
Shutdown procedures are performed by the system console
command:
The =SHUTDOWN command logs off all remaining sessions,
including the session logged on at the console. All system
processes are stopped in an orderly manner. Completing all
system activity and processing before shutdown, maintains
the integrity of all system tables and directories.
Shutting down the system consists of several steps:
telling users well in advance of a planned shutdown
warning users a few minutes before the shutdown
preventing anyone from starting a new job or session, or
printing new reports
clearing the backlog of reports before the shutdown
answering any console requests
shutting open communication lines
suspending or aborting any jobs, and aborting sessions
entering the =SHUTDOWN command
Chapter 9 “Halting System Activity” outlines
detailed procedures for shutting down the system.
