Oracle rips RedHat and 'sort of' launches a new Linux
Oracle曾诚意满满地派了100多个程序员帮助红帽子公司开发RedHat Linux发行版，慢慢地Oracle公司的员工逐渐掌握了RedHat的开发，相当于把RedHat架空了。RedHat被绿了一把😂。后来Oracle推出了自己的Oracle Linux，接着收购SUN公司。拥有了硬件基础。自此Oracle从硬件到OS再到数据库都有了自己的产品。推出了Oracle一体机。
Oracle made a weird announcement at its Oracle OpenWorld love-fest and trade-show. The company announced that it was releasing its own Linux: the Oracle's Unbreakable Enterprise Kernel for Oracle Linux.
Funny, and I thought Larry Ellison already had his own Linux, Unbreakable Linux, which Oracle introduced not quite four-years ago. Of course, Oracle Unbreakable Linux wasn't really Oracle's Linux. It was RedHat's RedHat Enterprise Linux (RHEL) with an Oracle Linux logo pasted on the front.

But, this time, Oracle swears its new Oracle Linux is different. The company claims that it's been optimized for Oracle software and hardware and that Unbreakable Enterprise Kernel is faster than RHEL To be precise, Oracle claims its more than 75 percent faster, as shown by Online Transaction Processing (OLTP) performance tests; 200 percent faster at InfiniBand messaging; and is 137 percent faster at solid state disk access than a "RedHat Compatible Kernel."
Speaking as the guy who designed and ran the very first Linux server benchmarks back in 1999, I'm not impressed by Oracle's claims. An expert can make any operating system look like the greatest thing since sliced bread and its rival look like a two-day old dead dog.
I'm sure on Sun/Oracle hardware, tuned Unbreakable Enterprise Kernel can beat un-tuned RHEL. So what? It will take more than Oracle's employees claiming Oracle's new Linux is great before I buy it.
Oracle's Unbreakable Enterprise Kernel for Oracle Linux--what a name!--is based on the stable 2.6.32 mainline Linux kernel. For some reason, a few idiots seem to think this represents a Linux fork. Nope. It doesn't. When you get past all the hype, Oracle's new Linux just a Linux distribution that's been optimized for Sun/Oracle hardware. Specifically, Oracle sees this as their Linux for the company's Oracle Exalogic Elastic Cloud and high-end, Non-Uniform Memory Access (NUMA) servers.

At the time though, according to Edward Scriven, Oracle's Chief Corporate Architect, Oracle will continue to sell its RHEL-compatible Linux under the name Oracle Linux. Still, Oracle insists in its press release that "Existing Oracle Linux 5 and RedHat Enterprise Linux 5 customers can easily upgrade to the Unbreakable Enterprise Kernel. No reinstall of the operating system is required."
What's more surprising is that Oracle also asserts that "Third-party applications that run on RHEL 5 should run unchanged on Oracle Linux with the Unbreakable Enterprise Kernel, while delivering significant performance and reliability improvements for end users."
So what the heck is Oracle Unbreakable Enterprise Kernel Linux? It sounds to me like it's just Oracle-branded RHEL that been tuned up for Oracle's hardware. Color me totally unimpressed.
Oh, according to reports, Ellison claims that Oracle's new Linux "will be more modern, it won't be four years behind the mainline, there'll be lots of timely enhancements from Oracle and the Linux community, and it will deliver much better performance."
OK, riddle me this. How can you be bleeding edge, offer stability for high-end applications, and stay compatible with a Linux that you claim is four-years behind the time? The answer to this conundrum? You can't.
Ellison also said, "We [Oracle] spend a lot of time finding and fixing bugs in RedHat Linux, and we have no problem with that--we do that with lots of operating systems."But sometimes when we fix a RedHat Linux bug, RedHat can take a very long time before making the fix. We'd fix the bug for our customers, and we'd send the bug off to RedHat for them to fix, and sometimes the fix would be made very quickly but sometimes not..
Really? You could have fooled me. Both RedHat and Oracle are leading Linux development companies, and I've not noticed Oracle cleaning up RedHat's messes. RedHat does just fine at cleaning up its own code thank you very much.
My take away from Oracle's announcement is that Ellison hasn't been able to damage RedHat nearly as much as he wanted to. So, now he's resorting to an announcement that's more noise than news. Sorry Oracle, RHEL's that been tuned for your hardware and software is interesting, but it's not much of a new distribution and the way you're presenting it will only confuse your customers.
