-SLAs measured in business hours / days.

-Business rules (e.g. auto-assignment) that vary based upon time of day / day of week.

For the latter a seemingly simple, albeit hacked, fix is to change the underlying data in the database, disabling one rule and enabling another at scheduled times. My only concern is whether the application actively caches this data and thus would have no reason to re-read it, and if so whether there is any mechanism to trigger a re-read?

For the former does anyone have any ideas on that?
