Oracle ships Oracle 10g Release 2 for Linux x86
http://www.oracle.com/technology/index.html
As an equal oppotunity database guy, just thought I would mention that Oracle has released a new version of their database. It is Oracle 10g Release 2. The only platform it is availabe on is Linux at this time, but support for other operating systems is coming, according to the site. The Windows version is suppossed to contain support for running CLR objects in the database.
