Re: Q: Is Oracle 24*365 possible?

There's an availability versus cost graph you can find floating around, which clearly demonstrates the exponential rise in cost for the last few minutes of availability per year.

If you can survive several hours per year down, it'll be much easier. If you can do a few hours per month or week, it becomes near trivial.
