Oracle Database 11gR2 on OL6 / RHEL6: Certified or Not?


There seems to be a little confusion out there about the certification status of Oracle Database 11gR2, especially with the release of the patchset which fixes all the issues associated with RAC installs on OL/RHEL 6.1.

Currently, 11gR2 is *NOT* certified on OL6 or RHEL6. How do I know? My Oracle Support says so! Check for yourself like this:

  • Log on the My Oracle Support (
  • Click the “Certifications” link.
  • Type in the product name, like “Oracle Database”
  • Select the product version number, like “”.
  • Select the platform, like “Linux x86_64” or a specific distro beneath this.
  • Click the “Search” button.

From the results you will see that Oracle Database is certified on OL and RHEL 5.x. Oracle do not differentiate between different respins of the major version. You will also notice that it is not currently supported on OL6 or RHEL6.

Having said that, we can expect this certification really soon. Why? Because Red Hat has submitted all the certification information to Oracle and (based on previous certifications) expects it to happen some time in Q4 this year, which is any time between now and the end of the year.

With a bit of luck, by the time I submit this post MOS certification will get updated and I will happily be out of date… 🙂



Update: It’s finally certified. See here.

  1. Maybe Q4 was somewhat too optimistic ? There have been rumors that Oracle may not support RHEL6 at all in favor of their own RHEL-rebuild: Oracle Linux 6. If that’s the case, I expect a lot of business to reconsider their reliance on Oracle en their vendor lock-in strategies.

  2. Hi.

    I’ve heard no such rumors from the guys at Oracle themselves, but who knows. I know nothing of the internal politics.

    I guess it’s a relatively low priority for Oracle since distros are a bit irrelevant, it’s kernels that matter. With RHEL5 or OL5 you can use the UEK and get all the cool features you need for an Oracle server. Without UEK you will have to wait for RHEL6 for a decent kernel.

    The installation guide for Cloud Control 12c includes instructions for installation on version 6, so it would appear it will be coming soon.
