Oracle announces the availability of its Unbreakable Enterprise Kernel Release 2 for Oracle Linux.
Oracle
has announced the general availability of the Unbreakable Enterprise
Kernel Release 2 for Oracle Linux.
Announced
on March 13, Unbreakable Enterprise Kernel Release 2 includes performance and
scalability enhancements that allowed Oracle to achieve record database
benchmark results, the company said. Based on the 3.0.16 mainline kernel,
Unbreakable Enterprise Kernel Release 2 also includes improved memory and
resource management, and is optimized to be deployed as a virtual guest.
Oracle
Linux continues to deliver timely Linux innovations, backed by real-world
testing, providing users a modern, scalable and reliable platform for their
business critical workload demands, said Wim Coekaerts, senior vice president
of Linux and Virtualization Engineering at Oracle, in a statement. Unbreakable
Enterprise Kernel Release 2 further demonstrates Oracles investment in Linux
technology and the community, and delivers on our goal to make Linux better for
everyone.
The
B-tree file system (Btrfs) is now production-ready with this release. Standard
in Oracle Linux, Btrfs supports data stores of up to 16 exabytes, is optimized
for solid state disks, is easy to administer and includes built-in data
integrity. Btrfs is known as the next-generation file system for Linux. With Btrfs
included, Oracle Linux supports large files and file systems, snapshots and
checksums for data and metadata; provides integrated RAID and volume management;
and simplifies administration, Oracle said.
In
addition, Oracle is offering technology previews of the popular dynamic tracing
mechanism, DTrace, and an instance isolation capability, Linux Containers, to
Oracle Linux support subscribers. Linux Containers allow multiple isolated
Linux instances (containers) to run on the same host. Processes running in
containers can have their own private view of the operating system, file system
structure and network interfaces, and their use of server resources can be
tightly controlled.
Oracle
Linux with Unbreakable Enterprise Kernel is extensively tested with demanding
workloads, both on third-party servers and Oraclesincluding Engineered
Systems such as Oracle
Exadata Database Machine, Oracle
Exalogic Elastic Cloud, Oracle
Exalytics In-Memory Machine and Oracle Big
Data Applianceto help ensure superior performance and reliability, the
company said.
Oracle
Linux is open source with a public git source code repository and compatible
with Red Hat Enterprise Linux.
