Unbreakable Enterprise Kernel for Oracle Linux

The Unbreakable Enterprise Kernel (UEK), included as part of Oracle Linux, provides the latest open source innovations, key optimizations and security for enterprise cloud workloads. This Linux kernel powers Oracle Cloud and Oracle Engineered Systems such as Oracle Exadata Database Machine. Oracle tests UEK intensively with demanding Oracle workloads, and recommends UEK for Oracle deployments and all other enterprise deployments.

Oracle contributes to upstream Linux kernel development with enhancements that benefit Oracle Database, middleware, applications and hardware, as well as our broad partner ecosystem. These enhancements are distributed to customers through UEK for Oracle Linux.

By selectively integrating the latest open source Linux capabilities into UEK while still providing application binary compatibility with the Red Hat Compatible Kernel, Oracle makes it easy to run the most demanding cloud and enterprise workloads without compromising stability and security. We test all our on-premises software, and run Oracle Cloud on UEK, ensuring you can achieve the highest scalability and performance with your current workloads and those of the future.

FEATURES	BENEFITS
DTrace	DTrace provides Oracle Linux customers with a comprehensive, dynamic tracing framework. Find and fix performance and stability problems easily and securely with DTrace enhancements like perf_events as Statically Defined Trace (SDT) probes.
Performance and Scalability Improvements	Notable performance improvements include: Improvements and fixes to NUMA balancing help resolve issues that could cause high I/O wait times when this feature was enabled. NUMA balancing is automatically enabled on systems that have multiple NUMA nodes. RDMA over Converged Ethernet (RoCE), a standard InfiniBand Trade Association (IBTA) protocol enables efficient data transfer for RDMA over Ethernet networks using UDP encapsulation to transcend Layer 3 networks. TCP-BBR, a feature that can be used to achieve higher bandwidth and lower latency for internet traffic can offer significant performance improvements for internet-based applications. BBR (Bottleneck Bandwidth and Round-Trip Time) is a scheduling algorithm that helps to control the transmit rate of the TCP protocol to reduce buffering by monitoring round-trip times against bandwidth bottlenecks to reduce TCP congestion.
Btrfs Improvements	Continued improvements in scalability, performance and stability for Btrfs are key features of this latest release.
Virtualization Improvements	Significant improvements to KVM functionality including: Secure Encrypted Virtualization (SEV) for AMD-V enabled. AMD’s Secure Encrypted Virtualization (SEV) feature that extends the AMD-V architecture has been enabled in UEK Release 5. Hardware that supports SEV can use this feature to run multiple virtual machines under the control of a hypervisor in a more secure fashion. User-Mode Instruction Prevention (UMIP) for Intel enabled. Intel’s UMIP feature has been enabled in UEK Release 5. UMIP is a security feature present in newer Intel processors, that can prevent the execution of certain instructions if the Current Privilege Level (CPL) is greater than 0. Paravirtual TLB shootdown implemented. Patches have been applied to implement a KVM paravirtual translation lookaside buffer (TLB) shootdown algorithm.
Linux Containers	It’s easier than ever to get the most out of your systems with Linux Containers (LXC) and Docker. Deploy applications quickly and efficiently with Linux container technologies. You can easily build your own or download ours from Oracle Container Registry, Docker Hub, and Docker Store.
Updated Drivers and Hardware Support	The UEK Release 6 supports a wide range of hardware and devices. In close cooperation with our enterprise solution hardware partners, UEK updates deliver support for the latest hardware features and driver updates.
Security Improvements	In addition to ongoing CVE fixes, notable security improvements include: Secure boot improvements. Secure boot is designed to protect a system against malicious code being loaded and executed early in the boot process. Secured platforms load only software binaries, such as option ROM drivers, boot loaders, and operating system loaders, that are unmodified and trusted by the platform. While the operating system is loaded, measures have been added to prevent malicious code from being injected on subsequent boots.

The Unbreakable Enterprise Kernel Release 6 is the latest UEK release and is heavily tested and optimized operating system kernel for Oracle Linux 7 Update 9 and Oracle Linux 8 Update 1 and later on the x86-64 and 64-bit ARM (aarch64) architectures. It is based on the mainline Linux kernel version 5.4.

The Unbreakable Enterprise Kernel Release 5 is the Oracle’s fifth major release of its heavily tested and optimized operating system kernel for Oracle Linux 7 Update 5 and later on the x86-64 and 64-bit ARM (aarch64) architectures. It is based on the mainline Linux kernel version 4.14.35.

главное отличие между Oracle Linux и Red Hat Enterprise Linux заключается в том, что сотрудничество Oracle разработало Oracle Linux в основном для корпоративных и облачных вычислений, в то время как Red Hat Inc. разработала Red Hat Enterprise Linux преимущественно для коммерческого рынка.

Linux является популярной операционной системой, а архитектура Linux состоит из таких компонентов, как ядро, системные библиотеки, системные инструменты, инструменты разработки и инструменты конечного пользователя. Ядро, являющееся сердцем операционной системы Linux, управляет устройствами, файлами, памятью и процессами. Системные библиотеки помогают получить доступ к функциям ядра. Пользователь может использовать графический интерфейс или интерфейс командной строки для выполнения задач с использованием Linux. Существуют различные дистрибутивы Linux, и Oracle Linux и Red Hat Enterprise Level Linux являются двумя из них.

Программа поддержки Oracle Linux предоставляет коммерческую техническую поддержку, охватывающую установку Oracle Linux, Red Hat Enterprise Linux или CentOS.

Что такое Red Hat Enterprise Linux

Red Hat Enterprise Linux — это дистрибутив Red Hat Linux. Вся официальная поддержка и обучение Red Hat сосредоточены на этой платформе Linux. Первоначальной версией Red Hat Enterprise Linux был Red Hat Linux Advanced Server. Red Hat переименовала его в 2003 году в Red Hat Enterprise Linux AS и добавила два варианта: Red Hat Enterprise Linux ES и Red Hat Enterprise Linux WS.

Несмотря на то, что Red Hat свободно предоставляет исходный код, он ограничивает свободное распространение официально поддерживаемых версий Red Hat Enterprise Linux. В целом, Red Hat Enterprise Linux — стабильный дистрибутив Linux. Кроме того, он обеспечивает долгосрочную поддержку.

Разница между Oracle Linux и Red Hat Enterprise Linux

Определение

Oracle Linux — это дистрибутив Linux, упакованный и свободно распространяемый Oracle, который частично доступен под лицензией GNU General Public License с конца 2006 года. Red Hat Enterprise Linux (RHEL), напротив, является дистрибутивом Linux, разработанным Red Hat и предназначенным для коммерческого рынка. , Таким образом, это принципиальное различие между Oracle Linux и Red Hat Enterprise Linux.

разработчик

Разработчик Oracle Linux сотрудничает с Oracle, а разработчик Red Hat Enterprise Linux — Red Hat Inc.

Пользовательский интерфейс по умолчанию

Пользовательский интерфейс по умолчанию является основным отличием Oracle Linux от Red Hat Enterprise Linux. GNOME и KDE являются пользовательскими интерфейсами по умолчанию Oracle Linux, в то время как GNOME является пользовательским интерфейсом Red Hat Enterprise Linux по умолчанию.

Лицензия

Кроме того, в то время как Oracle Linux имеет GNU GPL и различные другие лицензии, Red Hat Enterprise Linux предоставляет несколько лицензий на бесплатное программное обеспечение, а также двоичные двоичные объекты.

Менеджер пакетов

Менеджер пакетов — это еще одно различие между Oracle Linux и Red Hat Enterprise Linux. Oracle Linux использует диспетчер пакетов RPM, тогда как Redhat использует менеджеры пакетов Yum, PackageKit и RPM.

Основное использование

Другое различие между Oracle Linux и Red Hat Enterprise Linux заключается в том, что Oracle Linux в основном используется для корпоративных и облачных вычислений, а Red Hard Enterprise Linux в основном используется для рабочих станций, мэйнфреймов, серверов и суперкомпьютеров.

Заключение

Oracle Linux и Red Hat Enterprise Linux являются двумя дистрибутивами Linux. Оба с открытым исходным кодом и имеют монолитное ядро. Основное различие между Oracle Linux и Red Hat Enterprise Linux заключается в том, что Oracle Сотрудничество разработало Oracle Linux в основном для корпоративных и облачных вычислений, а Red Hat Inc. разработало Red Hat Enterprise Linux главным образом для коммерческого рынка.
