Questions concerning Oracle running on Redhat Linux
I have a few questions and am looking for more information on running Oracle on an Intel platform running Linux. First off I have read that Redhat has packaged a version which is Oracle certified. I was wondering if anyone knows where they keep up to date information on which kernels are certified or how kernel upgrade works with Linux and Oracle certification? It seems to me that it would be difficult for Oracle to certify every new kernel version that comes out or is that not how it works?
Second of all I was wondering how Oracle scales under Linux as compared to Sun hardware and Solaris? I could use an Enterprise 6500 or an Enterprise 10000 and run a decent size Oracle database on these boxes and I don't have to worry about having my database spread out amongst many servers, how would I accomplish this using intel hardware? Most Intel hardware I have seen doesn't have more then 4 cpu's and Redhat Linux hasn't been known to support more then two cpu configurations or more then a few gig of ram very well. Is there any documentation that talks about running high powered or large databases on Redhat?
Any information on these issues would be helpful.
