Many database applications have a very High Availability (HA) requirement. Examples include electrical and telecommunication utility management systems. Those systems must be available all the time to manage the systems; for electrical utility system, it includes adjusting production, or energy trading. Another example is global customer support system for companies like Oracle. A support system, with database application as the backend, must be available to log for each incoming request; calls come 24/7 for global companies. Manufacturers rely on database applications for inventory accounting and have large-scale factories running round the clock. Taking applications offline shuts down assembly lines.
