Friday Spotlight: Oracle Linux 7!

Happy SysAdmin Day and happy Friday, everyone! We’ll cover a couple of items in our spotlight this week.

First, and I’m sure this is no surprise, we’d like to spotlight the release of Oracle Linux 7! This release is another milestone in bringing the latest innovations and tools to our customers. You can read the press release, listen to Oracle’s Wim Coekaerts, read the blog post, read the data sheet, and the Frequently Asked Questions, review the documentation, or download it and give it a spin right now.

Second, we wanted to spotlight the release of the new Oracle Exadata Database Machine X4-8. This machine packs some serious punch and runs--you guessed it!--Oracle Linux. If you have any question about how well Oracle Linux can scale as an enterprise platform, you don’t have to look any further than this amazing pairing of hardware and software.

We’ll see you next week!

Mirantis Announces Support for Oracle Linux and Oracle VM

In May we announced the tech preview of the Oracle’s Distribution for OpenStack for Oracle Linux and Oracle VM. As we have been doing for many years with Linux and Xen, we plan to work with the OpenStack community and help make OpenStack an enterprise grade alternative for cloud deployments. 

We are very pleased with the Mirantis announcement today stating that Mirantis will offer Oracle Linux and Oracle VM as part of their supported operating systems and hypervisors options. Right from the beginning we stated that our approach to OpenStack will be open and collaborative (see Wim Coekaerts’ blog). We said we’ll work with the rest of industry and support our customers with any choices they make with regards to OpenStack distribution and today, with this announcement from Mirantis, we take another step in this direction.

With this announcement our joint customers can choose Oracle Linux as their operating system and Oracle VM Server as their hypervisor of choice and build an OpenStack deployment with end to end support. Customers can now use the most advanced capabilities in Oracle Linux like Ksplice and Dtrace and achieve better scale and performance with Oracle VM Server as well as receive 24/7 support directly from Oracle. Using an enterprise grade hypervisor and Linux distribution such as Oracle Linux and Oracle VM brings OpenStack deployment to a new level of reliability.  a higher level of reliability allows users to transition more workloads onto OpenStack confidently, knowing that each part of the stack is well supported.

On top of that Oracle Linux is fully supported as a guest operating system on the Mirantis distribution of OpenStack. Oracle Linux is free to use and redistribute including patches and updates with the option to purchase support subscription from Oracle. We believe that choosing Oracle Linux as guest operating system is the best and most cost efficient option and we would like every customer to have the option to use it.

Oracle will continue to collaborate with other OpenStack solution providers to allow them to offer Oracle Linux and Oracle VM as part of their solution. Our goal remains the same: jointly deliver great solutions and support experience for our mutual customers. We also look forward to working with other vendors to certify networking, storage, hypervisor and other plugins into the Oracle OpenStack Distribution.

We believe in keeping OpenStack open and collaborative and we will continue to focusing on:

  1. Working with other cloud solution to make sure they can integrate with Oracle Linux and Oracle VM
  2. Working with hardware and software vendors to integrate their solution with Oracle Distribution of OpenStack for Oracle Linux and Oracle VM
  3. Assuring that Oracle Linux is supported as guest operating system on any virtualization platform
We look forward to continue working with our partners and customers helping to make OpenStack a first class solution for the enterprise.

Learn about Btrfs, XFS, OCFS2 and More in Oracle Linux Training

Do you want to get hands on experience in creating and learning the benefits of the following file system?

  • The XFS file system - A high performance journaling file system that supports a maximum file system size of 100 TB and a maximum file size of 16 TB.
  • Btrfs - an open source general purpose file system that began in Oracle and is now contributed to by a number of major players. Btrfs provides extent-based file storage with a maximum size of 16 Exabytes.
  • OCFS2 - a general purpose, POSIX-compliant, shared disk cluster file system developed at Oracle. It allows multiple nodes to access the same disk at the same time. OCFS2 has two allocation units, blocks and clusters. OCFS2 supports block sizes ranging from 512 bytes to 4 KB and cluster sizes ranging from 4 KB and 1 MB. Cluster size is always greater than or equal to block size.

To learn more about these topics and many others, consider taking the Oracle Linux Advanced Administration course.

You can take this 5-day, instructor-led training course as a:

Friday Spotlight: Using Ksplice as a Diagnostic Tool with Oracle Support

Happy Friday! And for those of us in the US, happy Independence Day!

Our spotlight this week is on a new paper written by Oracle's Robert Chase (if you read the Oracle Linux articles over on Oracle Technical Network, you'll be familiar with his work). This paper focuses on the use of Oracle Ksplice -- well known as a kernel patching tool -- as a diagnostic tool to help you when working with Oracle Support. It's really a great use of the technology, have a read below:
