Oracle's Take On Red Hat Linux
darthcamaro writes "For nearly three years, Oracle has had its own version of Red Hat Enterprise Linux, claiming the two versions are essentially the same thing. But are they really? As it turns out, there are a few things on which Oracle and Red Hat do not see eye-to-eye, including file systems and virtualization. The article quotes Wim Coekaerts, Oracle's director of Linux engineering, saying, 'A lot of people think Oracle is doing Enterprise Linux as just basically a rip off of Red Hat but that's not what this is about. ... This is about a support program, and wanting to offer quality Linux OS support to customers that need it. The Linux distribution part is there just to make sure people can get a freely available Linux operating system that is fully supported.'"
Oracle Cluster File System. Whether you need it or not is up to you. Oracle also provides OCFS modules for Red Hat to make it easy on people.
Um, so basically it is a rip off of Red Hat just with Red Hat stripped out and Oracle's own filesystem added to the kernel
No no no no no.
The default filesystem shipped with RHEL and OUL is ext3. The clustered file-system shipped with RHEL is GFS, and with OUL it is OCFS2. OCFS2 is not compiled in-kernel within Red Hat Enterprise Linux, and must be mod-probed in as a separate - unsupported by Red Hat - module.

Again, wrong. RHEL 5 ships with Xen, and will support Xen until at least 2014. OUL also ships with Xen. Please remember, KVM has not shipped in *any* RHEL release (major or minor) yet. Only Red Hat internally knows the release agenda.

Oracle's binary compatibility claims are a myth.
I've installed a few UL Oracle systems. I wanted to be 110% sure that they would run the Oracle database. They just changed 'Red Hat' to 'Oracle'. They run fine...
i've never bothered to look at oracle linux, because i can get 'free' redhat through centos, and when i want paid support, i can get it directly through redhat.
without some other differentiation, what is oracle providing that isnt there from the others?
so yes, it is just a rip off of red hat.
You would ONLY use Oracle Linux to run your Oracle products on. You wouldn't use it for your file and print, or web server. They wouldn't want you to anyway.
It's largely a marketing thing. If you run your Oracle products on Oracle Linux, Oracle will support the entire software stack. That can be important to a lot of enterprise customers, no turf wars about who's fault it isn't.
As a bonus, the Oracle Linux support contract is (and should be) significantly cheaper than Red Hat (or Novell - the other supported Linux vendor). This is because they really only support those functions that are required to run the Oracle products. They aren't interested in supporting your file and print server etc. Whereas Red Hat and Novell have to support everything.
Can you imagine what Oracle would say if you had an issue that was borderline Oracle / OS and you were running CentOS? Even though CentOS is a re-badged Red Hat, it isn't Red Hat, and it isn't on Oracle's supported OS list.
The sensible thing to do would be to run Oracle Linux for your Oracle products and Red Hat (or CentOS if you didn't want support) for everything else. As they are all virtually the same, it's a lot easier for your administrators.
Ever stop to think
