Does it work with Debian/SuSE/Mandrake/some other distribution?
Oracle specify the Linux kernel version 2.2 or above and GLIBC version 2.1 with any window manager. In theory, any distribution that meets these requirements should work. In practice, unless Oracle have certified you distribution they may not support it and you may have more problems trying to complete the installation. Unless you have a very good reason to do otherwise I suggest you stick to RedHat Linux 6.x with all the patches you can get hold of. For the record, I’ve heard success stories will all those distributions. Some, however, consistently cause problems, Slackware being the main culprit.
