Forum OpenACS Q&A: Response to Oracle unsupported on Debian Linux?
But just what does it mean when Oracle "certifies" a particular Oracle product / OS combination? What ramifications, if any, does it have when you need to go to Oracle for support? I wasn't able to find any hard info on this on Oracle's websites or elsewhere, and am very much interested in your experiences...I've recently been in talks with Oracle Italy about this "certification" issue, due to some boneheaded decisions taken by execs at my company. It's not that Oracle won't give you support if you, either by choice or by accident, end up with a non-certified configuration, but it's possible that you'll have to pay high fees if they determine that you've gone outside the boundaries of your support contract.
Note that this is what I've been able to get out of these talks, it's possible that in other countries the situation could be different (but not by much, I think).
