Senior Vice President of Linux and Virtualization Engineering, Wim Coekaerts,
on Thursday, April 11 at 1 p.m. PT for an hour of tweets about all things
Please submit your questions on Twitter by using #AskOracleExec. Wim will be responding to questions using the @ORCL_Linux Twitter handle.
Wim Coekaerts is the Senior
Vice President of Linux and Virtualization Engineering for Oracle. He is
responsible for Oracle's complete desktop to data center virtualization
product line as well. Mr. Coekaerts
joined Oracle in 1995.
We sat down with Monica Kumar, Senior Director, Oracle Linux, Oracle Virtualization, and MySQL Product Marketing, to discuss the latest update on Oracle Linux.
Q. What are the latest Oracle Linux
A. Oracle Linux 5.9 and Oracle Linux
6.4 represent the latest releases of Oracle Linux. These releases are built on top of Oracle Linux 5 and 6 respectively and
include updates supporting new hardware and driver features, as well as bug
fixes and security updates. For additional details, please see the 5.9 release notes and 6.4 release
Q. Why would customers want to
update their Oracle Linux systems to the latest release? What advantages will
it give them?
A. Updates play a critical role
in the overall lifecycle of an operating system release. An update release provides an opportunity for customers to leverage new
hardware features as well as apply critical bug fixes and security
updates. Oracle Linux 5.9 is also a
consolidation of previously released errata published since the release of 5.8
– and the same holds true for 6.4. As part of Oracle Linux, we also offer an
innovative and modern kernel – Unbreakable Enterprise Kernel. The
combination of Unbreakable Enterprise Kernel with the latest bug fixes and new hardware support helps improve
performance, enhance stability and enable systems to remain secure.
Q. Why do customers choose Oracle
Linux? What do they get from Oracle Linux that they couldn't get by using
RHEL or SUSE or a non-commercially supported distribution?
A. Oracle Linux offers many
benefits. Key benefits include:
Latest innovations (with tracking mainline, optimizations from Oracle Engineered
Systems, and Unbreakable Enterprise Kernel is the culmination of
this technology excellence, offering enhanced performance, reliability and
a more modern Linux distribution), as well as unique features such as
Ksplice, DTrace, and support for popular file systems including ocfs2
besides the others.
Deployment best practices: over 100,000 hours of QA/day using Oracle
Linux – most tested distribution with enterprise workloads and over 160
world-class Linux support in 145 countries; by far the widest and largest
support network over Red Hat or SUSE
Q. What does Oracle give back to the
Linux kernel community?
Linux kernel development is focused on working with Linus and the mainline
kernel community, where we, like other Linux distribution vendors, contribute
significant amounts. Over time, those mainline development projects
trickle down into an OS distribution like Oracle Linux 6 through Unbreakable
Enterprise Kernel which is a great vehicle – and how we introduce new
Linux kernel features into Oracle Linux and provide it to customers.Oracle has a long history of developing
open source projects and working with the Linux kernel community. We are active contributors to many features
found in the mainline kernel today, including OCFS2, Btrfs, NFS, XEN, to name
just a few. In addition, our business
model for Oracle Linux is to focus on providing the best operating system for
mission critical workloads, and contributing the work we do back to the
mainline community. Our git repository for
the Unbreakable Enterprise Kernel is publicly available on oss.oracle.com/git so anyone can see our development work and
our contributions. In addition, we make
Oracle Linux freely available, including all of our errata, whether you have a
support subscription or not.
See this link
for more on Oracle’s contributions to Linux.
Q. Why is Oracle Linux better for customers than using the most
current version of Red Hat Enterprise Linux? What's the value for customers?
A. Oracle Linux including the Unbreakable
Enterprise Kernel is developed to provide high performance and stability for
mission-critical applications. Users
benefit from the innovations and improvements occurring in the mainline Linux
community, which we deliver rapidly with Oracle Linux. In addition, Oracle Linux is the most well
tested distribution for enterprise workloads, especially Oracle workloads. We
conduct over 100,000 hours/day of testing at Oracle using Oracle Linux. Additionally, support of Oracle’s Engineered
Systems plus the enterprise application knowledge that we have, is unmatched by
The technical support we provide
with Oracle Linux also includes important bug fixes that Red Hat may choose not
to release. For our customers, these
fixes are critical and it is one of the many reasons they choose Oracle
Linux. In addition, with capabilities like
zero-downtime kernel updates through Ksplice, they receive features that are
not offered by Red Hat.
Q. What is being planned for the
next release and what is the predicted timing of the next release?
A. Oracle continues to focus on
features which improve performance and the innovations found in the mainline
Linux community. We are currently
working on the next generation of the Unbreakable Enterprise Kernel for Oracle
We expect update releases for both Oracle
Linux 5 and Oracle Linux 6 and a new release of the Unbreakable Enterprise Kernel in calendar year 2013.

Hands–On Labs for Oracle Solaris, Oracle Linux and Oracle VM
We're taking the very popular OTN Sysadmin Days and going virtual! On Thursday, March 14, 2013, we're going to climb into a virtual platform and open our hands-on labs to you. This time it is for our Asia Pacific audiences.
You'll be able to perform real-world tasks with Oracle Solaris, Oracle Linux, and Oracle VM, and if you get stumped, jump into the chat window and ask for help from the Oracle experts.
There's one caveat: you'll have to do a little homework ahead of time. Load the virtual images onto your laptop, find the instructions, and make sure everything is working properly.
The Oracle Linux team is pleased to announce a new offer for
our customers with Premier Support subscription using Oracle Linux 6. We
have had many requests to provide a supported option for the XFS file system on
Oracle Linux and effective today customers with Premier Support subscriptions
using Oracle Linux 6 will receive XFS support, at no additional charge!
The XFS filesystem is a journaling file system known for high-performance and
scalability. With fast transactions, extreme scalability and near native
I/O performance, it is easy to understand the popularity of this versatile
filesystem. XFS support is offered on the Unbreakable Enterprise Kernel
Release 2 and also with the Red Hat compatible kernel. We are excited
about this new offer and the great news is, most of the features are already
available on your system today. Install the RPM package 'xfsprogs' from ULN using the command 'yum install xfsprogs', which provides utilities for managing XFS and you will be ready to create and deploy.
I have recently received several questions about how to find information relating to critical security updates or important errata releases for Oracle Linux. I realized that perhaps people were not aware of the new features and improvements to Unbreakable Linux Network (ULN), which assist users with common administrative tasks. I wanted to take a quick moment to highlight for you some of the changes we have made. First, there are two links you will want to bookmark:
Each link will allow the user to evaluate what updates have been made available for Oracle Linux.
With https://linux.oracle.com/errata you are able to view all errata releases available, listed by type, severity, advisory, summary and release date. In addition, you are also able to filter this list by release and/or type (Bug, Security, Enhancement) and if you select an item from the list you will receive additional details regarding the errata, including a description, related CVEs and the packages updated by the errata. You can also navigate to this same information by logging into ULN and selecting the 'Errata' tab from the options across the top.
For those who need information on security errata involving CVE identifiers (Common Vulnerabilities and Exposures) we have created https://linux.oracle.com/cve. This site allows you to gather information on important CVE identifiers, by providing a summary of all CVE offered through ULN. This summary is listed by CVE identifier and includes a brief synopsis and the release date. You can also filter the list by year. In addition, when you select a specific CVE identifier, you will receive additional details, such as information on CVSS v2 metrics as well as affected platforms.
We have been working to bring more features to ULN and these updates should provide more tools to simplify your administrative activities. Happy patching!
We are excited to announce the availability of a new feature in our Ksplice service, known as the Ksplice offline client. This new option eliminates the requirement on a direct connection to the internet to apply zero-downtime Ksplice patches. The Ksplice offline client allows the user to create a local YUM repository which will mirror the Ksplice channel from ULN (Unbreakable Linux Network). Once you have mirrored the channel on your local network, you simply apply the patch using the same Ksplice tools and commands you are already familiar with. Ksplice is available to all customers with Oracle Linux Premier or Oracle Linux Premier Limited support. Take a look at Wim's blog, where he provides an excellent example for how to setup and use this new service and if you are using Red Hat and want to try Ksplice, you can sign up for a 30 Day Free trial.
You'll be able to perform real-world tasks with Oracle Linux and if you have questions you can ask for help from the Oracle experts through chat window. There's one caveat: you'll have to do a little homework ahead of time. Load the virtual images onto your laptop, find the instructions, and make sure everything is working properly.
