Re: CentOS instead of RHEL?

As you've said, it's pretty clear, yes.

And regarding your last point. Yes, there are people out there running Oracle on CentOS in production. But it's usually those that don't really have in-house DBAs and just have an Oracle instance running somehow, and nearly forgot about it, until it broke some day. I wouldn't think that a lot of shops that run Oracle seriously would choose a non-certified OS to do so.

It's a bit like asking if you can fit monster truck wheels on your fiat 500. Can you make the car run? Sure. Can you take it for a spin and have some fun with it? Absolutely. Would you drive your kids across town to school with it every day? Probably not.

On another note, I've seen my fair share of Oracle bugs out in the wild over the years. Some tricky and involving long resolution times (due to bug fixes needing to be developed by Oracle). And that was on completely certified platforms and combinations. And frankly, I wouldn't want to introduce another unknown variable into the mix that has yet another chance of introducing some odd behavior due to some code path being different than a certified install of RHEL or OEL would have.

Thus, Oracle on CentOS in production? Big thumbs down from me :)
