I agree that Oracle is a fine system, and I have my doubts about the likelihood Oracle will fall over under fairly heavy loads. But I think the above is giving Oracle Corp a little too much credit. Corporations exist to make money, and the reason they prohibit doing anything with their software and then publishing it without their approval is because they want to control all the public perception of their software, whether deserved or not. Every user of any large software system (Oracle or otherwise) has their favourite horror story about the grotty corners of that software; commercially-licensed people just aren't allowed to prove it in public. It's not only the clueless Oracle is protecting themselves against; it's also the smart, accurate, but expensive corner-case testers. I get to complain that PostgreSQL is mostly fast but has terrible outlier performance problems. I can think of another system that I've used that certainly had a similar issue, but I couldn't show you the data to prove it. Everyone who used it knew about it, though.
