What Is The Biggest Difference Between Oracle Linux and Redhat?


I'm a sysadmin at a very large global enterprise. We are evaluating both Oracle and RHEL.

What is the main difference between the two?

Thank you for helping me. I appreciate it!

I have been working on both Linux (RHEL from RedHat and OLE from Oracle) in many projects for more than 10 years now.
firstly, RHEL is the main Linux Distribution whereas OLE is just a clone version of RHEL with some enhancements in Kernel to makes it more compatible with Oracle hardware and software.
secondly, there is no point to use OLE in heterogeneous Data Centers which they are equipped with multi-brand hardware.
Third, Oracle's policies regarding open source projects are unacceptable. As far as I can remember, projects such as Open Solaris, OpenOffice, and etc were owned by Oracle disappeared. Moreover, Oracle releases OLE to keep its product list complete on the other hand Oracle Linux fans are most people and companies that work with Oracle products. And the lack of knowledge in the Linux field leads to accepting Oracle's recommendations that my Linux works better and should be used. ‌Based on my experience in various projects as a Linux expert and SAN storage admins with an expert colleague in the Oracle database have obtained interesting results.
These projects have used OLE, RHEL, and CentOS Linux with IBM or HP servers also EMC, HPE or Hitachi storage.
And we found that:
1-RHEL Linux is better compatible with different hardware.
2-Not only are RHEL Documents more clear but also Red Hat has better support compared to Oracle.
3-RHEL and CentOS have better repositories and quicker security patching compared to OLE.
Finally, Red Hat (RHEL, CentOS, Fedora) communities are much greater and active than the Oracle Linux community.

Oracle Linux with little effort (adjustments) can enhance the Oracle DB Performance. And most of the Oracle Products are tested under it.

Hi Nawazish,

I have worked with both products. I strongly recommend Oracle Enterprise Linux.

The reasons are as follows :
1. Oracle Enterprise Linux has some key features which are suitable for running enterprise class workloads. KSplice is one of such key feature.

2. If you are planning to run Oracle database / MiddleWare / E-Business on Intel/ Linux then select Oracle Linux. Because you get one support portal "Metalink" to manage your support issues for all the software components. In case you run RHEL, you will end up in managing Oracle and RHEL support separately.

3. Oracle Cloud Infrastructure (OCI) runs on Oracle Linux, and Oracle Exadata runs on Oracle Linux. In case you plan to migrate your Oracle workload to Oracle Cloud (OCI) or Exadata in future, the migration will be seamless.

4. Oracle has announced Autonomous Linux during Oracle Open World few weeks back. I am sure they will get all Autonomous features in Oracle Linux in future versions.

5. Commercially Oracle Linux gives you better price as compared to RHEL. Simply compare Oracle Linux Standard Edition with Ref Hat Linux with 24x7 support and you will understand the difference. This is because Oracle Linux support comes from Oracle Metalink 24x7 by default. Thats not the case with Red Hat

Let me know in case you need additional help.

Thanks

Shrikant

Hi, Did you see this Oracle Linux review ? -> https://www.itcentralstation.com/product_reviews/oracle-linux-review-42176-by-it_user600741
Is the information given in that review enough for satisfying your curiosity? If not, please update.

Just the location of the repository for the most part. If you're running Oracle databases on RHEL I recommend purchasing Oracle X-8 hardware and running Oracle Enterprise linux instead, you will save a lot of money in the long run.
The biggest advantages OEL has is that if you buy the Oracle hardware you get support for the OS for free. If you run databases on Oracle hardware your core licensing costs are usually cut in half. Oracle Linux on Oracle hardware also allows for the use of OVM (like vmware) The main disadvantage of the OVM over VMware is that the OVM software is still underdeveloped a little and requires a little more effort for disk functions.

Oracle Linux is developed by Oracle Corp. Oracle ULN (unbreakable Linux (UEK) as they call it, has come into existence since the time Oracle started to invest in Cloud computing. It is again Kernel-based under GNU license. It is now majorly used in Oracle cloud platforms and Oracle Exadata or Oracle Database appliance.

RHEL Linux is developed by Red Hat which also uses Kernel-based under GNU license. RHEL can be used in local desktop, servers and also it can be used on IBM mainframe Hardware (Z13/Z14) as Zlinux and LINUXONE platform as well. They both have similar interfaces (GNOME) except Oracle has KDE as well. Moreover, they use the same terminology and commands to execute on their Linux versions. Oracle Linux uses RPM packages where RHEL Linux using RPM as well as YUM packages and both support containerization and dockerization.

Oracle Linux is best suited for Oracle products because of its support and compatibility with the Oracle products.

Hi Nawazish,

I have experiences with both products and both companies.

Both Linux distributions are binary compatible with very similar functions and utilities. The same is also CentOS, that is build on the same source codes.
I choose RHEL for:
1. better support (at least for problems that I faced with)
2. quicker security patching
3. additional products that are build on RHEL (RHEV, Middleware products, GlusterFS)
I'm not sure about the performance of Oracle DB on Oracle Linux with comparing to RHEL. I would like to see some independent performance analysis.

I like Red Hat more as a company, because It is not Evil like Oracle. I have very bad experience with Oracle products licensing and software audit.

These is the reasons, why I chose the RHEL.

Regards,

Petr

I share this article with you, the publication is from this year, where this difference is explained. I hope this information is useful.

Oracle Linux is RHEL, rebranded. It includes the Oracle Unbreakable Kernel which you can read about on the Oracle website. I have found no practical extra value from it.

Redhat support of the Redhat OS is better than Oracle support on a Redhat OS.

We have used both RHEL and OEL for running large Oracle DBs.
If your company only uses Oracle products exclusively then OEL might be an appropriate choice.
If your company has other non-oracle products, then RHEL probably would be an appropriate choice for you.
We are currently running RHEL in the Major Public Clouds as well, and it is supported fully.
Please consider ease of updates as well, as for us yum update with lifecycle management from Satellite works very well and can be based on specific application business needs (e.g. SAP Hana).

There is no real difference between RHEL and OL (Oracle Linux).

You can even run OL (with a Red Hat kernel) so it’s the same. OL is free, so you could run all Dev/Test systems without the support and only pay for support for production systems. You can download updates for free, you don’t need a subscription.

Support costs are cheaper on OL and OL performs better with its optimized kernel (especially when running Oracle databases)

Personally, I can’t see a reason to run Red Hat (as opposed to OL).

My recommendation is to increase modularity and reduce costs by using SUSE.
