Author: User

Oracle Linux, known as Oracle Enterprise Linux, is one of the oel,linux releases. Oracle launched its first release in early 2006 to better align Oracle software and hardware support. OEL, commonly referred to as Oracle Enterprise Linux, because Oracle provides enterprise-class support plan UBL (Unbreakable Linux), so many people call OEL as Indestructible Linux. In September 2010, Oracle Enterprise Linux released a new version of the kernel--unbreakable enterprise Kernel, specifically optimized for Oracle software and hardware. Most importantly, Oracle database performance can be increased by more than 75% on Oel. According to the project website, Oracle started with Red Hat Linux, removed the Red Hat logo, and added Linux bug fixes.

Unbreakable Enterprise Kernel

Oracle launched an impregnable enterprise-class kernel for Linux (Unbreakable Enterprise Kernel, abbreviated as:UEK), UEK is a high-speed, modern, A reliable Linux kernel, a kernel optimized for Oracle software and hardware, is part of Oracle Linux (formerly Oracle Enterprise Linux). To date, the latest version of Unbreakable Enterprise Kernel is unbreakable Enterprise Kernel Release 3 quarterly Update 5. The Uek kernel is used as the default operating system kernel, while the Rhel compatible kernel is available, the Uek core can support both Oel 5 and Oel 6, and the use of both cores can be supported by Oracle and the price is consistent;

With the joint efforts of Oracle's Linux operating system, database, middleware and hardware teams, Uek has the following outstanding features:

    • High-speed: OLTP performance tests show performance over red Hat 75%, speed up 200% for InfiniBand information processing, and 137% increase in access to solid-state disks.
    • NEW: Optimized for large NUMA server architectures, improved power management and energy efficiency, and granular control over CPU and memory resources.
    • Reliable: Supports data integrity extensions and T10 protection information patterns (T10 Protection information Model) to prevent corrupted data from being written to storage, hardware fault management improves application uptime, and performance counts and traces are less expensive.
    • Optimized for Oracle: With Oracle's hardware, database, and middleware, it achieves optimal performance, reliability, and availability, and is validated. This is not the other Linux can not be a candle.
