Oracle Brings Real-Time Kernel Patching To Oracle Enterprise Linux

Posted by timothy on from the any-old-time-you-want dept.

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.

    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...

      Wrong.

    Hardly the GPL that causes issues when the license for ZFS was deliberately created to be non GPL compatible. If Linux had been licensed with any other license then Oracle would have written a license to avoid that one too. ZFS was meant to be a differentiator to make Solaris a better choice for the Enterprise than Linux.
