It has been my experience that this is somewhat true. If there is a known fix that has not been fully regression-tested you can often get MS to cough it up for free[1], as well they should. The bigger issues tend to be determining the cause of a new problem that has not yet been resolved, or one that occurs as a result of interaction with a 3rd party driver, software, hardware, etc. > As I said, we could never go in production with Linux. I run Oracle 9i RAC on a linux cluster at work, and have been in production for a couple of years. In that time, I've dealt with some _very_ interesting (read: crappy) problems with everything from fibre-channel driver problems to completely locking systems. I had RedHat, Oracle, and Dell all on the line several times working out these issues. Here's the interesting thing: This was no different from any other new install on any major OS, regardless of the level of support. For most 'enterprise, server-level' users, the support you get from RH/IBM/MS/Sun is all about the same today. Some issues are easy to troubleshoot and resolve, and some require escalation. The biggest issues we've run into lately are getting issues escalated to an appropriate level within Oracle. RedHat has not been an issue, and their support has continued to improve over the past several years. However, their licensing fees are also now much more in line with their competition, but that is to be expected. --jeff [1] Contrast that with Linux where the fix is always free to all users, because any fix has to be released under the GPL.
