Why is a restart necessary?
When you start the system up, Day 0 for each FRU is driven by the time the system is started up and the relative timezone of the FRU. For example, if you start the system up at 1am EST, then that would be 10pm PST, so day 0 for any PST FRUs would be the day before Day 0 for any EST FRUs. For users this is particularly noticeable for the optimizer and its run days and can cause problems.
...
The above issues are overcome by providing the ability for the system, once started, to automatically restart any single component on a timed basis, which is a time relative to its own time zone. Thus, specifically, it is possible to configure the system to restart each FRU at an appropriately quiet time for the business.
Mandatory Database sp083_system_parameters
A time of day may be set in the database at which the APIAgent, GanttRouter and FRUs(separately per FRU) self-terminate. The standard System Monitor recovery mechanism then ensures that the halted components are restarted. When an FRU restarts it resets its "day zero" to "today". Each component log the reason for halting, so it is possible to differentiate these halts from any caused by an outage.
