| In the Spotlight | | | OpenELA initiates a documentation repository for the community
OpenELA has announced the creation of a user documentation repository, where contributors are now able to add notes and documentation as they work through the Linux source code.
Oracle has contributed sections of the Oracle Linux 8 and 9 documentation to establish the groundwork for the OpenELA documentation repository. This serves as an initial framework for topics, encompassing critical areas like Managing Core System Configuration, Establishing System Users and Authentication, and Configuring Networking. This collaborative effort enhances the accessibility and comprehensiveness of the OpenELA documentation, laying the foundation for a valuable resource.
Oracle Linux: 2023 year in review

| Product Highlights | Oracle Linux Virtualization Manager 4.5 delivers enhanced monitoring and reporting
This release supports Oracle Linux 8 Kernel-based Virtual Machine (KVM) compute hosts and is based on the 4.5 release of the open source oVirt project. This server virtualization management platform can be easily deployed to configure, monitor, and manage an Oracle Linux KVM environment with enterprise-grade performance and support from Oracle. Here's a highlight of Oracle Linux Virtualization Manager 4.5.
Oracle Linux Automation Manager automates Leapp upgrades
Combining the automation capabilities of Oracle Linux Automation Manager with the upgrade framework of Leapp – in other words, automating Leapp upgrades – can significantly reduce manual work and the time involved in those important operations. Together, both technologies provide the option to scale while managing in-place upgrades for tens or hundreds of systems or more. Exploring the practical side, let's see how we can integrate these solutions with a few straightforward playbooks, while keeping the process simple.
The value of Oracle Linux Support
Oracle Linux Support provides customers with the flexibility to choose which systems they want to self-support and which ones should be covered by a support subscription, allowing access to 24x7 enterprise-grade support for various technologies such as Linux, KVM, Kubernetes, automation, and containers.
Support covers on-premises, cloud-based, and virtual environments. The benefits include an automated online Linux patching service for proactive security compliance, quick assistance from subject-matter experts in building cloud infrastructure, and timely resolution of multivendor issues. Oracle Linux Support offers a single, dedicated point of contact, abundant choice and flexibility, and a cost-effective solution without lock-in, making it a valuable option for fortifying businesses.

| Developers Corner | Yes, Virginia, there is page table sharing in Linux
Myth, legend, and marketing are all based on some element of truth. The same is true for page table sharing in Linux. Let's find out what exactly is Huge PMF Sharing, a little-known method of page table sharing that exists in the Linux kernel.
Estimate the size of a vmcore
Many system administrators are hesitant to set up core dumping on their Linux systems because of the large amount of space it can consume or the amount of time it takes to write out large memory segments to disk. In this article, we provide tools to estimate the size of a core dump with different vmcore size-reducing features enabled, and present a tool for estimating the size of those core dumps. The resulting vmcore is streamlined to only the data required to debug a kernel failure, with most user space and cache content removed.
Crash hotplug: Kernel handling of CPU and memory hot un/plug
CPU and memory scaling of Linux virtual machines involves adding and removing CPUs and memory as quickly as possible to scale up or down the virtual machine to meet customer demands.
When conducting scalability tests with kdump, we identified two challenges:
the loading time for kdump extended significantly beyond the completion of the scaling process, and
(intentional) kernel panics often failed to trigger a kdump, leading to system hangs To overcome these undesirable behaviors Oracle developed the Crash Hotplug Implementation. |
