The great Oracle Linux vs Red Hat Enterprice Linux RHEL Debate. Who has better support and who is more open?
I found this very funny but who do you believe or who do you believe is better?
This came from Red Hat Enterprise Linux Newsletter Email group;
>> It is less evil. And going to Oracle Linux means dealing with Oracle >> support… or, lack thereof, and utterly uncoordinated support, for very >> small values of “support”. >> >> It took me a *month* to get a box fixed, and that included two weeks >> emailing with an engineer in Chile, and three separate managers “taking >> ownership” of the issue…. > > I also know someone who has good experience with Oracle. > > Even the free support on the Oracle Forums (at: > https://forums.oracle.com/forums/forum.jspa?forumID=822 ) is good — > so far I’ve posted 3 questions, and 3 of them were answered by the > Oracle employees within a week.
Um, right. Meanwhile, this box was under warranty, and had hardware issues. And when I complained that the engineer in Chile was being pulled off to respond to other issues, and so sometimes I’d get several emails a day, other times, I’d email results of tests, and it would take him 2-3 days to get back to me, I got a new engineer… WHO ONLY WORKED NIGHTS.
As a comparison, I had a similar problem with a Dell box, and there was an FE out within two weeks, *and* one manager had “taken ownership”, *and* when I had a problem a couple months later with another box, that same manager contacted me. My manager and co-worker have had similar, though not quite as extreme, experiences with Oracle, and we have *no* intention of buying Sun/Oracle ever again.
—- Oracle linux has been pretty much blacklisted by red hat. That’s why a number of changes were done to how red hat pushes out kernel patches; specifically to stymy their efforts. Also, having an issue responded to within a week is horrid, especially in an enterprise environment. Usually when I am having an issue, I need a resolution FAST.
Don’t drink the oracle koolaid. Copy your /home directory and any customized files from /etc to a safe place, and then reinstall RHEL. The support is worth every cent.
( Hmm, now it becomes an Oracle Linux discussion… which is not what I originally intended. 😛 )
So tell me how Redhat is less evil — isn’t opensource supposed to be no vendor lockin? So if Redhat is doing this, then customers are locked into RHEL.
A lot of people say that Oracle does not have deep knowledge in Linux, as Oracle Linux is just a clone of RHEL — however, Oracle internally uses Oracle Linux for most its software development. I don’t think a typical environment is much more complex than the ones inside Oracle (Oracle Linux is used to develop Oracle Database, Fusion Middleware, Oracle Grid Engine, E-Business Suite and other Oracle Applications on Oracle Linux — according to Oracle). Oracle develops its own enhancements for Oracle Linux as well, not to mention Oracle’s own kernel. I don’t believe Oracle engineers calling Redhat support for technical issues.
And Oracle was able to roll out Oracle Linux 6 a week or 2 after RHEL 6 release, while the wait for CentOS 6 was months long.
I know that many people hate Oracle, but simply saying that Oracle Linux does not work / not as good / not worth the $ is not fair to Oracle (or any others, as we know that Redhat wrote around 10% of the patches in the kernel, 90% of the code was developed by IBM, Intel, AMD, and even Oracle — eg. BtrFS, OCFS). Oracle enhances Linux and uses Linux for Exadata and ExaLogic.

You’d be surprised actually. Oracle itself has admitted to patching the kernel with certain performance tweaks dedicated exclusively for their products; however they haven’t submitted the changes to the mainstream kernel development. So, essentially they’re taking the kernel, tweaking it, and not giving back to the community. Now under GPL, they don’t have to release their code, but it still leaves a sour note in a lot of peoples’ mouths. Especially because one of their touted selling points is that “they clean up red hat’s problems.”
Not to mention they’ve only certified the tweaks for Oracle software. That means they could cause your other mission critical application to crash every 2 seconds, but so long as your database is running oracle will give it a stamp of approval.
Also, they have stripped out a number of open source solutions in order to include their own proprietary solutions (so yes, vendor lockin). They have removed GFS/GFS2 and replaced it with their proprietary competitor OCFS2. They have removed redhat cluster suite and replaced it with the closed source oracle clusterware.
If any these things break, who can help you? Oracle. If you’re using RHEL, anyone who uses RHEL, Cent, or SL can probably help you. I don’t want to turn this into a distro war – Oracle linux is made for running oracle databases. That’s it, and it’s very good at doing that. However pretty much every other case you’re going to be better covered by RHEL or its derivatives.
Also, Oracle/Sun support sucks. Compare experiences with Red Hat to experiences with Oracle, there is a pretty stark contrast. Red hat was first and foremost a company to provide support for otherwise free software. Oracle on the other hand is just a money making machine.
I don’t care which one people use really, I use cent and SI for my own work, and RHEL for production boxes. I still have yet to see a good reason to use oracle.

Not correct — according to lwn.net, for the past few releases, Oracle did contribute to the latest Linux kernels by sending patches to Linus & the LKML.

Oracle ships 3 kernels with Oracle Linux:
1) 100% compatible RHEL kernel (ie. a rebuild from the same source) 2) RHEL compatible kernel with bug fixes done by Oracle 3) Oracle Unbreakable kernel
So if the application really crashes due to Oracle;s changes, use the older but 100% compatible RHEL kernel.
There are over 7000 paying customers using Oracle Linux, and I don’t believe Oracle would put changes in that is designed to crash other applications.
In fact, software products that are competing with Oracle are built on Oracle Linux, for example the Open Grid Scheduler, and Univa Grid Engine (another fork of Sun Grid Engine). I am sure others might use Oracle Linux, but I am more of an HPC guy.
See the example on this page, even the low level hardware interaction code does work on Oracle Linux: http://gridscheduler.sourceforge.net/projects/hwloc/GridEnginehwloc.html

OCFS2 is open source AFAIK:

In the end, in the user space, Oracle Linux, RHEL, CentOS, and SL are mostly idential.

Same here 😀

Oracle software developers use Oracle Linux for software development – and Oracle does not only has DB products, it also has middleware, cloud computing software, embedded software (Berkeley DB for example), and Java!
So, can one really writes a kernel that runs all of the software that Oracle has, but only crashes or slows down one inhouse application?

If only the first who enters the market can do business, then we will have a very different world then we have today. 😀
And how is Redhat not a money making machine? RHT is close to making $1B in the next FY (FY2012?). And Redhat charges more money than Oracle for support.

I use Oracle Linux for my development & build machines, and the thing that is good is that with Oracle Linux one can become a paying user without reinstalling.
