Oracle 10g Release 2 is available for Linux X86
I am finally back in my office and I have just kicked off a complete download of 637MB of zip file, its coming down at 110kb/Sec, so should run for about 1.5 hours. All I then need to do is free some space and reload Linux as my Linux box / main PC crashed some time back irrevocably! So it may take some time to be in a position to load 10g R2 and test it.
