Introduction One of Oracle’s top 10 predictions for developers in 2019 was that a hybrid model that falls between virtual machines and containers will rise in popularity for deploying applications. Kata Containers are a relatively new technology that combine the speed of development and deployment of (Docker) containers with the isolation of virtual machines. In the Oracle Linux and virtualization team we have been investigating Kata Containers and have recently released...

This blog entry was contributed by Maxim Kartashev In the previous post I focused on the static analysis capabilities of the gcc 7.3 compiler. Warnings issued at compile time can point to the place in a program where an error at run time might occur, thus enabling the programmer to fix the program even before it is run. Not all run time errors can be predicted at compile time, though, and there are good and bad reasons why. For instance, there might be many annoying false...

Oracle Linux Kernel developer Lance Hartmann contributes this blog post on using SPDK, the Storage Performance Development Kit. Introducing the SPDK Slated to arrive soon in the developer yum channel via ULN, the Storage Performance Development Kit SPDK is an open-source project providing user space tools and libraries for writing high performance, scalable storage applications built largely but not solely around a user space NVMe driver. Harnessing the power of multi-core...

We are pleased to announce the release of the Software Collection Library 3.2 to the Unbreakable Linux Network and the Oracle Linux yum server. Software collections are primarily intended for development environments which require access to the latest features of software components such as Perl, PHP, or Python. For these environments, you need to minimize the disruption of system processes that rely on the versions of these components. The Software Collections library allows...

Oracle Linux developer Subhra Mazumdar has been working on scalability improvements in the Linux scheduler. In this blog post, he talks about some of his latest work. At Oracle, we run big database workloads which are very susceptible to how the OS chooses to schedule threads. Spending too much time in the scheduler to select a CPU can translate to higher transaction latency (at a given throughput) or lower maximum achievable transaction throughput in TPC-C workloads. In this...

Ksplice is a cool technology and I wanted to share a few things that you might not know about it along with a few tips on how to get started if you aren't already using it. 1. New patching advances As the security landscape evolves, so does Ksplice to keep up with more and more complex patches. These new changes and techniques allow Ksplice to safely patch even more of the kernel entry assembly code, even on heavily loaded systems. To date, Ksplice is the only technology...
