However, almost all of our engineered systems use the UEK, which includes Exadata (X2-8 with X2-2 shortly), Exalytics, Exalogic, Big Data Applicance and the Database Appliance. We know that more and more of our non-Exa customers are shifting the UEK (or UEK2) each day, but I don't have any specific numbers.
is there any official or semi-official information regarding how widely used is Oracle UEK to run Oracle 10g/11g database (RAC or single-node) versus running Oracle database on Red Hat Linux or on Oracle Linux with Red Hat kernel ?
The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence. Well, in my opinion, a higher market share does not reflect the quality or reliability of a product. Take MS Windows for example. Unfortunately, the reason for success is often not due to knowledge and experience, but rather due to fear and sheep effect or herd behavior.1 person found this helpful
Perhaps you can use other arguments or questions to help you to make a decision, eg.:
Oracle has a better understanding of what Oracle products require than Red Hat.
Oracle takes full responsibility for the OS and Database, no finger pointing.
Oracle tries to provide a better product than the RHEL kernel.
The Oracle UEK kernel contains Oracle driver software, not available for RHEL 6 or later.
Oracle updates are free of charge, RHEL requires a subscription.
Oracle as a company is about 20 times bigger than Red Hat.
There can be reasons that require the use of the original RHEL kernel, for instance if the vendor of a specific driver for your hardware demands it. But otherwise...
thank you Avi and Dude.
