Oracle Brings Real-Time Kernel Patching To Oracle Enterprise Linux 52

prisoninmate writes: Oracle's Unbreakable Enterprise Kernel (UEK) Release 4 is an important engineering effort and introduces performance improvements and enhancements for some of the most essential components, including CPU schedulers and Automatic NUMA Balancing, along with powerful new features, such as real-time kernel patching, which is possible thanks to the Ksplice open-source extension of the Linux kernel 4 branch, which lets users to apply patches to the running kernel without the need to reboot the system, thus improving security and simplify the management of cloud infrastructures.

    Welcome to 2008?

    So Oracle takes linux tech and uses it for their own purposes. Okay fine. How about donating some source code to the ZFSonLinux project? What's that you say? Patents, you say?

    I would probably be an Oracle "fan boy". Ksplice is not new. They "bought" it a few years ago, one of the main reasons it took so long forTorvald's kernel to get hot kernel patching.

    Ksplice will only update the OS, it cannot update drivers or firmware of any kind (Storage arrays, NICs, etc...) you still need to bounce for that. Learned the unfortunate way when we needed to update drivers for a buggy as be damned big blue flash array. (Very recent history...)

    Also as I RTFA, SELinux does not yet work with an Oracle DB. When it does it will be amazing, but it has not happened yet...

      Are you sure about that?

      Wrong. [redhat.com]

        Wrong.

        And this is what is wrong with redhate. They paywall their knowledge base. Their whole business is based on open information, but they hide theirs. They can really fuck off sideways.

          Or, as usual, do the same thing with CentOS for free.

          I don't get the animosity towards RH. I haven't paid for their support in years and years, but when I did, it was so I could call somebody when something went wrong and get reliable help quickly.

          I only ever had to call a couple times, but the support I got was better than I ever received from most companies.

          Oracle? Oracle is on the opposite end of that list. I won't touch Oracle ever again if I can help it. I am aware of the things Oracle brings to the table but it's not worth the pain.

            I agree. RH support is amazing. They follow-up on tickets almost instantly and they know their product well. Even on weird or very specialized questions they usually come back with the solution quickly.

    read a joke about Slashdot shilling oracle Linux for the next slashvertisement. At least I thought it was a joke.

    • Couldn't DICE/slashdot just get an Oracle server running "ORACLE UNBREAKABLE REAL-TIME LINUX" and use it for their daily operations? So that they'll know how good it is, particularly on their bottom line?

    If it's unbreakable why do they have to patch it?

    "Yeah, this thing will never break! Hang on a sec while I fix it..."

    • by Jeremi ( 14640 )

      I does seem a bit ballsy for Oracle to name their product 'unbreakable', considering the fact that they broke Java so badly that it was pretty much banned from all web browsers...

    If you need to live patch your kernel you've got a misdesigned application. Failures happen and if you can't design your application for redundancy, don't expect uninterrupted service.

    If you need to live-patch kernels in your cloud infrastructure, you need to go back to the drawing board because you don't have a cloud, you have a SPOF.

    "Real time" like with bounded deadlines, right? Or maybe you mean "live", "online" or "nonstop"?

  • KSplice is not news, and it works for other distros too, including Ubuntu (while it takes a while to add support for new hardware enablements). It was cool before kernel 4.

    But kernel 4 series is not supposed to support hot plug out of the box?

  • KSplice is only available to Oracle Linux customers with Oracle Linux Premier Support, which is $1.3k/year+ http://www.ksplice.com/ [ksplice.com]
  • I have admins that keep telling me they can't keep the OEL machines up to date more than 3 months because Oracle releases patches on a 3 month schedule. Even then, we have to have a patch set made just for us.

    I'll believe it when I see it.

"Spock, did you see the looks on their faces?" "Yes, Captain, a sort of vacant contentment."
