Oracle Linux 6Oracle has introduced the release of industrial distribution in Oracle Linux 6.4, created on the basis of packet-base Red Hat Enterprise Linux 6.4.

Distribution will be available for free download in the assemblies for x86 and x86_64 (iso-size image of 3 GB). In addition, since March 2012, for Oracle Linux open unlimited and free access to the yum-repository with binary package updates with error recovery (errata) and security issues.

Distribution of the differences between Oracle Linux 6.4 on RHEL 6.4 is celebrated bug fixes, updated drivers for network devices and storage systems. As part of Oracle Linux 6.4 comes with two options packages Linux-kernel: a classic version of the company Red Hat (kernel-2.6.32-358.el6) and created by the Oracle kernel package is Linux, based on the branch 3.0 bekportirovaniem some more new features series kernels 3.x (kernel-uek-2.6.39-400.17.1.el6uek). By default, the basic package includes two cores, but prepared in the Oracle kernel package is loaded by default. Ready-core binaries from the Oracle-compatible c RHEL distributions and src.rpm-packets presented on the site, where you can also download and others present in the distribution packages. Oracle does not impose any restrictions on the supply of trained in the Oracle kernel to third-party products.

Main features of Oracle Linux 6.4:

– Official support solutions based on the filesystem XFS. XFS file system is now part of the number of options is included in the standard contract for technical support;
– Delivery of offline-client Ksplice, allows to install patches to upgrade the kernel on the fly without stopping the system, including systems with no direct internet connection, using the local infrastructure deployed on the mirror repository Oracle Linux;
– Integration of the first stable version of DTrace dynamic debugging for Linux, suitable for everyday use. Earlier packages DTrace is in beta testing and positioned just for preview.

Improved support hypervisor Xen:

– support for more than 128 GB of RAM for paravirtualized guests, enable drivers MCE (Xen Machine Check Exception), which allows the hypervisor to handle events MCE;

– integration driver PCPU (Xen Physical CPU), allowing off bind physical CPU in dom0;

– Added support for PAD (Processor Aggregator Device) to configure and manage all processors.

From the experimental kernel features Unbreakable Enterprise Kernel 2 states:

– Support for checking the validity of kernel modules for digital signatures. In the process of loading a module of its signature will be verified with sewn into the core of a public key, depending on the settings of modules without the correct signature can be blocked;
– Support isolated environments on the basis of light-weight containers LXC (LinuX Container), based on the use of cgroups and separate namespaces. In LXC-container is not used virtualization, and on the basis of already running Linux kernel creates a single view of the operating system with the structure of FS and the network stack;
– Subsystem tmem (Transcendent memory), which increases the efficiency of the use of physical memory in virtual environments and provide a return on the host system selected guest environments, but not engaged in the memory areas;
– Support for DRBD (Distributed Replicated Block Device), allowing to provide a block device mirroring between machines (RAID1 over the network) to create a fault-tolerant configurations.

At the core of Unbreakable Enterprise Kernel 2 dropped support for the following experimental features:

– DIF / DIX for SCSI;
– FS-Cache;
– fsfreeze;
– IPv6 in IPVS;
– Matahari;
– multicast ping (omping);
– system of information storage and reporting SIGAR;
– Trusted Platform Module (TPM);
– Trusted Boot;
– vios-proxy.

Features available only with the kernel that is compatible with RHEL:

– driver Brocade BFA;
– driver for the mechanism of error detection and correction EDAC, present in – processors Intel Sandy Bridge;
– Fibre Channel over Ethernet (FCoE);
– Kernel Media;
– live-snapshots for KVM;
– additional high-performance network driver for KVM;
– Parallel NFS;
– mechanism of remote logging audit;
– SR-IOV (Single Root I / O Virtualization);
– system monitoring through SNMP.
