  • What's new in Red Hat Enterprise Linux 8.3? Enhanced container tools, more system roles and new cloud admin tools just for starters

    Red Hat Enterprise Linux (RHEL) 8.3 will be available in the coming weeks. In this post we'll take a look at some of the highlights and important new features that are planned for RHEL subscribers.

    A RHEL release has many constituencies. RHEL has to meet the needs of system administrators who crave system stability and predictability, and developers who want flexibility and new language and software choices. With new system roles, a major RHEL container tools update, cloud administration updates and more, RHEL 8.3 delivers for those who depend on enterprise open source to run today's businesses.

    The third update since RHEL 8's release in early 2019, RHEL 8.3 continues the six-month cadence of minor releases. By offering a predictable, time-based release cycle we help drive new features in a timely fashion without compromising the reliability of RHEL that our users and customers depend on.

  • Collect JDK Flight Recorder events at runtime with JMC Agent - Red Hat Developer

    JDK Flight Recorder, or JFR, is an event-based production environment profiler available from OpenJDK 8u272 forward. Being a HotSpot-native feature, JDK Flight Recorder performs with extremely low overhead in terms of how it uses both space and time.

    While JDK Flight Recorder collects basic Java runtime information by default, it is also possible to use JFR’s Event API to collect custom events. Developers who want to collect application-level events must actively define and instantiate them in their application source code.

    In this article, we’ll show you how to use JMC Agent and the JMC Agent Plugin to instrument your application classes with event-emitting code. When you use JMC Agent with the JDK Flight Recorder Event API, you do not need to shut down the JVM and recompile the application code.

  • New custom metrics and air gapped installation in Red Hat 3scale API Management 2.9 - Red Hat Developer

RHEL 8.3 updates target digital transformation

  • RHEL 8.3 updates target digital transformation

    With an eye toward easing digital transformation projects, the latest version of Red Hat Enterprise Linux includes improved container tools, new security profiles and the addition of several System Roles, including ones for kernel settings, SAP HANA and NetWeaver.

    Red Hat also improved RHEL performance, adding updates to Tuned, which is a set of pre-configured profiles. Tuned allows IT shops to take better advantage of Red Hat's multi-architecture, enabling software to run faster across a number of different hardware architectures. Also, Red Hat Insights continues to remain available by default for RHEL systems. As part of version 8.3, Red Hat added administrator views specifically for SAP HANA deployments.

    System Roles makes both common and complex RHEL configurations more consistent and accessible to a wider range of IT skillsets in large organizations.

Red Hat Enterprise Linux (RHEL) 8.3

  • Red Hat Enterprise Linux (RHEL) 8.3 Announced With Updated AppStream

    Exactly three months after the beta release of Red Hat Enterprise Linux (RHEL) 8.3, the Red Hat team has now announced a new stable version of the RHEL 8 platform called RHEL 8.3.

    The latest stable release aims to deliver more stability with cloud-native innovation by introducing new security profiles, enhanced performance capabilities, and updated container tools.

RHEL 8.3 Released With TSX Disabled By Default

  • RHEL 8.3 Released With TSX Disabled By Default To Avoid Mitigation Overhead

    Red Hat Enterprise Linux 8.3 is out today as the latest release of the RHEL8 platform.

    The latest stable release of Red Hat Enterprise Linux 8, RHEL 8.3, is focused on expanded Red Hat System Roles support, updates to Tuned, new SCAP profiles, updated Application Streams, and other enterprise-minded stability enhancements. Some specific changes to note with Red Hat Enterprise Linux 8.3 include:

    - RHEL 8.3 is now disabling Intel Transactional Synchronization Extensions (TSX) by default. Disabling of TSX by default is done in the name of security and to remove the performance penalty of having TSX Asynchronous Abort mitigations for Xeon Cascade Lake processors. TSX can be enabled with the "tsx=on" kernel parameter.

    - New module streams for Ruby 2.7, Nginx 1.18, Perl 5.30, and Node.js 14. The streams for Python 3.8, PHP 7.4, and HTTPD 2.4.

Red Hat Enterprise Linux 8.3 adds roles...

    The world’s favourite grown-up headgear-themed Linux distro, Red Hat Enterprise Linux, has reached version 8.3, Red Hat has announced. Identical in most respects to 8.2, the new version adds pre-packaged configuration, compliance and container options to ease the daily toil of devops in the modern IT environment.

    There are new Red Hat System Roles, which guide and automate OS configurations to speed installation by what RH charitably describes as those with ‘a wider range of skill sets’. New roles now include kernel settings, log settings, SAP HANA, SAP NetWeaver and management.Tuned, a set of pre-configured, architecture-aware performance profiles, has also been updated.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
