Coming from a *Nix background, I now work in a Windows shop. The Windows environment is not bad, performance and stability on the 64bit architecture seems fine, HOWEVER, you really need to make sure you're on the latest patches before you install Oracle. There were a couple of good bugs in Windows 2003 that we hit. They weren't specific to 64bit though come to think of it, more specific to Windows Server 2003.

Hi Please, I need references about Oracle with Windows 64. Some of my clients "love" Windows and don´t want to change it. Stability ? Performance ? etc. Thanks !
