If a server is shutdown abruptly, or planned. IE SIA is shutdown, and the server remains shutdown for n# of hours. What happens to schedules that are scheduled between those offline hours?
Do they start kicking off when server is brought online?
Yes, unless they are scheduled to wait for an Event. If that is the case, then they will start running after the event fires.
Note that the order of servers coming up can be problematic. If, for example, the AJS starts running jobs before the IFRS is up, the scheduled jobs may fail.
