87.6 hours downtime per year = 3.65 days per year = 99% uptime = Two 9s. Four 9s = 99.99% uptime = 53 mins downtime per year.

Four 9's?

That's 87.6 hours of downtime per year.

No particulary something to brag about.

Hey, wait a minute.

I just had 4 oracle senior SE's assure me that if I implemented RAC and

I would have four nines of uptime (or better), and that it was very
easily done.

I guess Oracle doesn't eat it's own dogfood?
