Announcing New Features for Ksplice

Offline Support for userspace patching is now available in Ksplice.

For customers hosting their own yum repositories, or those with restricted access to outside update channels, you can now integrate Ksplice userspace patches into your existing offline Ksplice patching procedures.  This expands the initial support with online patching capabilities and provides the maximum flexibility and choice for customers managing critical updates.

If you have wanted to use Ksplice for userspace but were restricted by the online service, you are now able to take full advantage of all the services and features available.

 Let us know what you think.

FRIDAY SPOTLIGHT: Engage in Oracle Linux Community Site

Hi everyone, 

This Friday I wanted to cover one of the interactive sites we have at oracle.com that you can participate. Oracle Linux Community  is part of the OTN communities. It gives you an opportunity to search and ask questions to experts in Oracle products. Here's an FAQ to explain what it is and how you can get engaged. We have many engineers and Oracle Linux enthusiasts monitoring the questions. We also keep our technical documents in this area so please check the documents tab regularly.


What is Oracle Community website? 

Oracle Community is a home for communities across Oracle, with more joining regularly. It is a content-rich, engaging, and interactive platform for sharing information, questions, and comments about Oracle products and related technologies. Every conceivable nuance of using Oracle products and supported standards is covered. 

 Is this the same as the OTN forums?

 What you may know as the OTN forums has now become the OTN Product Communities. These product communities--including Database, Fusion Middleware, Server & Storage Systems, Java, Cloud Computing, and more--now live alongside other communities like Oracle User Group Community and My Oracle Support Community.

 What is the Oracle Technology Network (OTN)?

Oracle Technology Network is the world's largest interactive community of Oracle developers, admins, and architects. In addition to the Product Communities you can find here on the forums, you can learn more about the Oracle Technology Network by reading About Oracle Technology Network (OTN).

Who moderates these forums?

Many OTN Product Community discussions are moderated by product managers, My Oracle Support Community discussions are moderated by technical support engineers and Oracle User Group Community is moderated by the Oracle User Group team. All of these spaces are frequently visited by knowledgeable users from the community

Announcing Oracle Cloud Machine: Can you have your cake and eat it too?

The appeal of public cloud services is undeniable and unstoppable. But, a vast majority of applications are constrained from moving to the public cloud due to data residency and privacy laws, intellectual property concerns, and sensitivity to latency of the traffic to and from the public Internet.

If the phrase ‘Private Cloud’ sounds like an oxymoron to you, you are not alone. 

IT vendors have tried but largely failed to deliver on the tall promise of “private cloud” – the notion of a cloud behind your firewall with all the benefits of public cloud services without the need to send your data over the Internet to a public cloud service. Too many corners were cut in offering such solutions. According to Nirav Mehta, Vice President of Product Management, Oracle, who spoke to hundreds of CIOs and IT directors, the biggest reasons why the promise of Private Clouds has not been realized is it is either ‘private’ or a ‘cloud’ but not really both at the same time.

Today, we are very proud to announce the availability of the first offering in this category – the Oracle Cloud Machine

Attend: Thursday, March 24 (8am-4pm ET) Listen to Live Webcast, participate in chats and be part of this exciting event 

We have taken the Oracle Cloud for IaaS and PaaS and extended it to your premises. The service, called Oracle Cloud at Customer, allows companies to place an Oracle cloud server within their own data center, essentially turning one of the basic concepts of cloud computing inside-out, according to Thomas Kurian, president of Oracle product development.

The setup is a hybrid cloud structure that allows a company to run whatever workloads it chooses on premises or in the Oracle cloud, with a common set of tools, APIs, and experiences. The workloads can shift between the environments. And Oracle will be responsible for the operation and maintenance of the server, just as it would be for customers of more standard, public cloud services.

  We believe it is the industry’s most complete solutions for deploying public cloud services “behind your firewall”. Here's why:

  • There is a single point of accountability for the cloud services delivered behind the customer’s firewall – Oracle. Hardware, software, and all ongoing management of the entire stack is provided by Oracle.
  • The same software that underpins the Oracle (public) Cloud is delivered with the Oracle Cloud Machine as well. Oracle also ensures that this congruence between the private cloud and public cloud is maintained by frequently updating the Oracle Cloud Machine with the same updates that we deploy in the Oracle Cloud.
  • Oracle Cloud Machine is managed remotely by Oracle Cloud Operations using a secure, remote connection that honors least privilege principles to ensure that you, the customer, can truly have a hassle-free experience of consuming cloud services and NOT managing the underlying infrastructure. Every customer is assigned a Technical Account Manager (included in the cost of the service) who helps with capacity planning, performance optimization, and addressing any services issues.
  • Oracle Cloud Machine is sold as a set of subscription services. You buy IaaS and PaaS services and not hardware and software. The pricing mirrors the Oracle (public) Cloud pricing for a very simple buying experience for the customer. Pick the service you want and you choose whether you want to consume it over the Internet or entirely behind your firewall.  Oracle takes care of everything else. 

 Lastly, while we are unbeatable when it comes to running Oracle workloads. Oracle Cloud Machine runs on Oracle Linux which is  provides high performing, secure platform for both Oracle and non-Oracle workloads.  Providing advanced scalability and reliability for enterprise applications and systems, Oracle Linux delivers truly open cloud with great performance and is used in all x86-based Oracle Engineered Systems.

 Delivering true simplicity takes a lot of thought and effort. We are proud to have delivered a solution that has simplicity at its core. The  kind of simplicity that could only have come from hidden sophistication and innovation. We look forward to working closely with you to  realize your vision of a true cloud behind your firewall enabled by Oracle Cloud Machine. 

Yes. You may eat that cake and have it too!

FRIDAY SPOTLIGHT: CVE-2015-7547 - Ksplice solves glibc flaw with zero-downtime and no disruptions

This week we have seen a new vulnerability making the rounds involving glibc. The issue at hand involves a couple of libraries (libresolv and libnss_dns), which are used commonly with tasks like DNS lookups. Using the function getaddrinfo() could generate a stack buffer overflow with larger replies, which in turn could be used maliciously to trigger an exploit through attacker-controlled domain names, attacker-controlled DNS servers or man-in-the-middle attacks.

The glibc upstream project released a patch for this issue and most distributions (including Oracle Linux) have released updated glibc packages containing this fix.  Since glibc is a core system library that is used by almost every application on a system, updates to the package typically require restarting applications and best practices would suggest a system reboot.  

Oracle Linux customers with premier support have the advantage of our Ksplice services, which makes it possible to install both kernel and user space updates without the need to restart applications or reboot the system.  If you would like more information about Ksplice and Oracle Linux, please visit our website.
