Oracle Linux Review
I like the Operating System alignment with Oracle Database.

Valuable Features

The most valuable feature in Oracle Linux is its design. Oracle Linux is built with features to align very closely with Oracle products and specifically the Oracle Database. For example, it’s delivered with the Unbreakable Enterprise Kernel which is a kernel developed and optimized by Oracle for Oracle products.
It’s an important part of the system that makes Oracle Database so powerful.

Improvements to My Organization

The Oracle Linux system is configured, by default, to schedule I/O for database usage and this I/O management plays an important part in database performance.

Room for Improvement

Dynamic tracing could be improved. In Oracle Linux, you have some very powerful (for example "perf" or "systemtap").

If Oracle can deliver such tools like dtrace for linux (publicly), this would help albeit actually dtrace is delivered through the Unbreakable Linux Network.

Use of Solution

I have used Linux since 1997 and Oracle Linux since its availability in 2007.

Stability Issues

We have never encountered any stability issues.

Scalability Issues

We have never encountered any scalability issues.

Customer Service and Technical Support

I usually use forums, Google and My Oracle Support (MOS )Knowledge Base (a great tool) to find answers to my questions. I never used Support Engineers to resolve issues related to Oracle Linux.

Previous Solutions

I used Red Hat Linux solutions before, but Oracle Linux is better engineered to run Oracle products.

Initial Setup

The initial setup is not complex. If you understand Linux basics, it won’t be a problem.

Pricing, Setup Cost and Licensing

Oracle Linux support is not free but the product is free. You can use it and test it safely for your tests environments. As soon you run your production, purchase a support if you have to access patches etc.

Other Solutions Considered

We evaluated Red Hat Linux a couple of years ago, but both products are very close. Only Oracle Linux has specific features that can be optimized for Oracle products (Database, Engineered systems etc.)

Other Advice

If you are searching for an operating system build to run your Oracle products, then Oracle Linux is the best product to do that.

Disclosure: I am a real user, and this review is based on my own experience and opinions.
