Application Streams

⏩Oracle UNIX operating system eight introduces the conception of Application Streams, wherever multiple versions of user house parts are often delivered and updated a lot of oft than the core software package packages.

⏩Application Streams contain the mandatory system parts and a variety of applications that were antecedently distributed in package Collections, still as alternative products and programs.

⏩A list of Application Streams supported on Oracle UNIX operating system eight is offered here.

System Management

⏩Dandified Yum, a replacement version of the yum tool supported DNF technology, maybe a package manager that installs, updates, and removes packages on RPM-based UNIX operating system distributions.

⏩The cockpit, associate easy-to-use, light-weight and easy nonetheless powerful   remote manager for GNU/Linux servers, is associate interactive server           administration interface that provides a live UNIX operating system session via    an internet browser



RPM Enhancements

➤Oracle UNIX operating system eight ships with version four.14 of RPM, that introduces several enhancements and support for many new options

Installation, Boot and Image Creation

➤inst.addrepo=name boot parameter has been side to the installer. you'll use this parameter to specify a further repository throughout associate installation.

➤By default, the Oracle UNIX operating system eight installer uses the disk cryptography specification LUKS2 (Linux Unified Key Setup 2) format

Kernel

➧The info command has been updated to acknowledge and show signature info for modules that area unit signed with CMS and PKCS#7 formatted signatures.

➧A set of kernel modules are moved to the kernel-modules-extra package, which implies none of those modules area unit put in by default; as a consequence, non-root users cannot load these parts, as they're additionally blacklisted by default.

➧Memory bus limits are extended to 128 PiB of virtual address house and four metallic elements of physical memory capability. The I/O memory management unit (IOMMU) code within the UNIX operating system kernel is additionally updated to alter 5-level paging tables.


➧The early dump feature allows the crash kernel and the initramfs to load early in order that it will capture more info, together with early kernel crashes.

Containers and Virtualization

➧New instrumentality tools: podman, build and scope, compatible with Open instrumentality Initiative (OCI), area unit currently offered with the Oracle UNIX operating system eight. These tools are often wont to manage a similar UNIX operating system instrumentalities that area unit created and managed by lumper and alternative compatible container engines.

➧Q35 machine sort, support for KVM, that may be a lot of fashionable PCI Express-based machine sort, is currently offered for KVM

➧Additional info is enclosed in KVM guest crash reports, that makes it easier to diagnose and fix issues once exploitation KVM virtualization


Filesystem and Storage


➤Enhanced Device plotter Multipathing

➤SCSI Multiqueue driver allows block layer performance to scale well with quick solid-state drives (SSDs) and multi-core systems

➤Stratis, a straightforward resolution to manage native storage

➤XFS support for shared COW information extents, shared copy-on-write (COW) information extent practicality, whereby 2 or a lot of files will share a typical set of knowledge blocks. This feature is analogous to repeat on write (COW) practicality that's found in alternative file systems, wherever if either of the files that area unit sharing common blocks modification, XFS breaks the link to those common blocks so creates a replacement file.

Identity Management


➤Several major identity management (IdM) options and enhancements, together with session recording, increased Microsoft AD integration and new watchword syntax check
➤IdM server and consumer packages area unit distributed as a module; the IdM server module stream is termed the DL1 stream and it contains multiple profiles (server, dns, trust, client, and default)

Networking

➤iptables network packet filtering framework has been replaced with nftables; the nftables framework includes packet classification facilities, many enhancements and provides improved performance
➤iptables-translate and ip6tables-translate commands area unit currently offered to convert existing rules to their tables equivalents, thereby facilitating the move to Oracle UNIX operating system eight
➤IPVLAN virtual network driver allows network property for multiple containers by exposing one mack address to the native network
➤Networking, UDP, and TCP updated to unleash four.18 with improved performance


Security


➧OpenSSH updated to unleash seven.8p1, enhancing access security

➧LUKS2 (Linux Unified Key Setup) is currently the default format for encrypted volumes

➧OpenSCAP has been updated to the discharge one.3.0 with enhancements to the command-line interface still as consolidation of OpenSCAP API are self-addressed

➧SELinux currently supports the map permission feature, to assist forestall direct access to numerous classification system objects and introduces new SELinux booleans

➧Transport Layer Security (TLS) one.3 is enabled by default in major back-end cryptologic libraries


Thank you✌✌✌
