My personal experience with Oracle on Linux (Score 1)

is that Oracle has a bunch of clueless people working on their Linux stuff. These people have much to learn about writing drivers for Linux. And yet they blame their poor scalability on Linux kernel. For example, they just figured out that they were using wrong type of Linux kernel on our database servers running Red Hat Linux six months after the servers are deployed to production. We had weekly kernel crashes on these Oracle servers until I questioned their choice of kernel.
