Oracle’s Linux offeringsOracle Linux (formerly Oracle Enterprise Linux or OEL)

● Derived from Red Hat Enterprise Linux sources (origin unknown)

● Ships with 2 different kernels

● Oracle named “Red Hat Compatible” kernel● Claimed to be functionally equivalent to RHEL kernel, not tested or

certified by Red Hat or Oracle for RHEL compatibility● The “Oracle Unbreakable Enterprise Kernel” (UEK) for Linux

● The default non-Red Hat Compatible kernel created by Oracle● Contains Oracle-only code not accepted by the upstream open source

community

Oracle Linux Support (formerly Oracle Unbreakable Linux or OUL)● Oracle's support program for Oracle Linux (OL)

● Claims to offer support for instances of Red Hat Enterprise Linux

Key points of differentiationRed Hat Enterprise Linux Oracle Linux

● Developed collaboratively with the Linux community and partners

● Built on community-accepted and -supported open source code

● Based on publicly available RHEL sources● Claims RHEL compatibility but no testing to

validate● Includes non-GPL code (dtrace & ksplice)

● >62% share of the paid Linux market1 ● <3% share of paid Linux market1

● >1000 ISV partners ● <100 total ISV, IHV, and SI partners2

● New version releases average every 2.5-3 years, with updates every 6-8 months

● Dependent on Red Hat source, released only after recompilation and redistribution

● Certified for use on all major x86 hardware vendors including: HP, Dell, IBM, Fujitsu, Intel, AMD and Oracle

● Variants available for IBM-z, IBM POWER systems

● Vendor-certified for use on some HP, Dell, and Oracle servers; OL with “Red Hat-compatible” version not certified by IBM for use on IBM x86 servers

● x86 only

● Certified and supported guest on VMware and Hyper-V

● Supported but not certified by Oracle as a guest on VMware

● Red Hat is the leading commercial contributor to the Linux community: sign-off authority for >37% of Linux kernel

● Oracle makes minimal contributions to Linux kernel, specific to Oracle hardware and applications

Support: Red Hat vs Oracle

Red Hat Enterprise Linux subscription

Oracle Linux support plan

● 10-year life cycle support for major releases● EUS subscription to enable additional year of

support on minor releases

● <3-year life cycle for UEK● EUS support not available; users must upgrade

to next minor release to continue to receive bug fixes

● Published list of supported APIs across major and minor releases

● No published supported APIs ● Right to discontinue support for features or

releases at any time

● Support staff has direct access to Red Hat engineering

● Support staff has no access to Red Hat engineering

● Subscribers have access to Red Hat engineering

● OL customers cannot escalate requests to Red Hat Engineering

● Access to complete road map available to subscribers for strategic product direction

● Complete OL road map unavailable since RHEL road map unavailable to Oracle

Support: Red Hat vs Oracle

Red Hat Enterprise Linux subscription

Oracle Linux support plan

● Subscribers participate in feature requests and product direction

● Limited customer ability to drive new features and functions into the OS

● Delivers Red Hat authored, signed, and tested binaries and eventually delivers RHEL sources

● OL binaries based on RHEL sources; delivery delayed while Oracle rebuilds

● Collaborative engineering relationships with hardware providers

● Competitive relationship with other hardware vendors

Support for Red Hat Enterprise Linux: Red Hat vs. Oracle

Red Hat Oracle

Third party hardware issues● Red Hat identifies and resolves driver

and other hardware interaction issues● Red Hat submits the resolution

upstream

Third party software issues● Red Hat works with the customer’s ISV

to resolve Red Hat Enterprise Linux issues and either issues a patch or advises the ISV engineers

● In order to claim that patches and updatesdelivered by Oracle are built from the same code as RHEL, Oracle would have to wait for a Red Hat patch to become available and then rebuild and redistribute it.

● Working with Red Hat ISVs to fix bugs in Red Hat Enterprise Linux or RHEL-certified applications would be less likely than Oracle waiting for Red Hat to issue a patch.

● If resolution requires an OS upgrade, the user must convert to Oracle, or try an older version of the application, as Oracle is not authorized to and doesn't deliver Red Hat Enterprise Linux minor or major releases.

● Oracle patches applied to Red Hat Enterprise Linux may invalidate the hardware and software support policies of those vendors, and will invalidate security certifications.

10 questions for which customers should ask Oracle for a written response1. Red Hat has engineering and support relationships with HP and IBM to ensure that Red Hat

Enterprise Linux performs well and reliably on those vendors’ platforms. Does Oracle have the same level of relationship to ensure that Oracle Linux works as well and has full support on IBM and HP server hardware?

2. How can Oracle claim 100% binary compatibility with Red Hat Enterprise Linux even if they have no copies of the OS running in-house and they don't do any compatibility testing?

3. The Oracle Linux FAQ states that Oracle takes source code that Red Hat makes publicly available. What is the site they use to obtain Red Hat source code?

4. Doesn't Oracle have to wait for Red Hat to fix a bug in Red Hat Enterprise Linux and make the source code available to the public before Oracle can rebuild and redistribute it? How long does that take?

5. Are there cases when this delay has been or can be many weeks?

10 questions for which customers should ask Oracle for a written response (cont’d)

6. Under what circumstances would I be required to purchase both a Red Hat Enteprise Linux subscription and an Oracle Linux subscription for my RHEL server?

7. Can Oracle guarantee that all of my Red Hat Enterprise Linux certified applications and hardware will be supported by their respective vendors after I switch to Oracle Linux?

8. Will I be able to continue leveraging my investment in Red Hat Satellite Server for Oracle Linux deployments?

9. Does Oracle provide us with the same Extended Update Support that Red Hat provides for its minor releases?

10. Can Oracle provide me with a complete road map for Oracle Linux?
