I know we're here on the Oracle Linux blog, but we know a lot of our users are also using Oracle VM. The Oracle VM product management team has put together a very short (just a few minutes) survey that would really help them get some feedback on how people are using it in their environments.
If you're an Oracle VM user, we'd love to get your feedback!

Some notable highlights include:
- The turbostat tool is now included with the kernel and can be used to provide information on processor topology and statistics, such as temperature and frequency.
- Updates to the bonding driver to enable the ethtool command, which shows useful data like link aggregate speed and duplex mode.
- The SHA-512 hash algorithm is now available for signing kernel modules during installation.
- The ability to use swap files that reside on NFS shares is available as a technology preview.
- Xen EFI support has been added.

Happy Friday everyone, we hope you had a great week!
It was an exciting week for us with the release of Oracle Linux 7.1. You can read about the update, learn how to get it, read the documentation, and more.
We also have two fantastic blogs from Oracle Senior Vice President Linux and Virtualization Engineering, Wim Coekaerts. Wim talked about Oracle Linux and MySQL 5.6, and secure boot in Oracle Linux 7.1. There's a lot of great information there, so have a look through it for your Friday afternoon reading.
Have a great week and we'll see you next week!

We had a fantastic webinar this week with our friends from Dell. The webcast covered the Dell Integrated System for Oracle Database (DISOD), and how it works with Oracle Linux to help you get fantastic performance.
If you missed the live event, you can now view the archive version on-demand, at your convenience.
We'll see you next week!

One of the coolest, yet perhaps not best known, features of running Oracle Database and Oracle Linux together is Database Smart Flash Cache. Wim Coekaerts put it this way on his blog earlier this week:
"Basically, if you have flash devices attached to your server, you can use this flash memory to increase the size of the buffer cache. So instead of aging blocks out of the buffer cache and having to go back to reading them from disk, they move to the much, much faster flash storage as a secondary fast buffer cache (for reads, not writes)."
So, this gives you a way to significantly increase performance on your systems running the Oracle Database and Oracle Linux. How cool is that? Wim then goes on to describe the few easy steps it takes to get it up and running.
Have a great week!

Today we are announcing a technology preview for the Oracle Linux software collection library. The software collection library provides useful features to both developers and administrators, by providing access to later versions of packages and libraries commonly used in development, such as Perl, PHP and Python.
Under the software collection library, these packages can be installed on existing systems, without overwriting the base packages delivered by the platform release. The software collection library delivers the latest features and enhancements to many popular packages, which developers and administrators can easily integrate into their projects and solutions. The Oracle Linux software collection library can be downloaded today from public-yum. Please review the release notes for more information and send us your feedback and questions on the Oracle Linux forum.

Dell-Oracle Joint Webinar: What would you do if your database latency dropped 96%?
Are you struggling with finding the right infrastructure that supports the performance demands of ALL your Oracle workloads, while balancing budgetary constraints and limitations? Does your applications and database instances require a lot of horsepower but you can’t cost-justify deploying them on expensive, high-end infrastructure?
Dell offers a solution for this “middle-band” of applications, one that balances performance with total cost of ownership. The Dell Integrated System for Oracle Database (DISOD), pre-installed with Oracle Linux with Unbreakable Enterprise Kernel, is delivered ready to be installed with Oracle Database 12c, 11gR2, or 10g, providing the flexibility to fit into any existing infrastructure. Oracle Linux brings the latest Linux innovations to market, delivering performance, scalability, and reliability for enterprise applications, enterprise-class, low-cost support.
Attend our upcoming webinar March 4, 2015, at 9:00 am PST (11am CST) to find out :
- Why DISOD delivers easy to procure, yet flexible to expand architecture perfectly suited to meet your needs
- How your database can perform better without investing in high-end systems
- Why Oracle Linux with Unbreakable Enterprise Kernel is the best choice for Oracle Database and Dell systems

You might have seen Antoinette O'Sullivan's post earlier this week about a new video for Ksplice. This video is part of the Oracle Learning Library, which is a tremendous resource for Oracle product information. There is a lot of content there on Oracle Linux, and if you're using other Oracle technologies, too, there is information on Oracle VM, Oracle Database, Oracle Cloud, Engineered Systems, Oracle Enterprise Manager, Oracle Fusion Middleware, the list goes on and on. If you have not checked it out, I highly recommend heading over there for some Friday afternoon learning.
We'll see you next week!

In last week's Oracle Virtualization Spotlight, Honglin Su discussed new Oracle VM Templates for Oracle Database. Here's an excerpt:
The Oracle VM Templates for Oracle Database provides a framework that fully automates the creation of a Single Instance, Oracle Restart (Single Instance/HA) or Oracle Real Application Clusters (RAC) configurations in an Oracle VM environment. In a matter of minutes the versatile and powerful Oracle VM Templates for Oracle Database can be cloned into any number of VMs which could be deployed as a Single Instance, Oracle Restart (Single Instance/HA) or Oracle RAC of any number of nodes.
Of course, this is the Oracle Linux blog, so why am I referencing new Oracle VM Templates? Because these templates of course run Oracle Linux! Here are the highlights of the new templates:
NEW in 2015 Templates:
- Yum@Deploy support(11gR2 & 12c) - Allows running yum install/update during first boot/deployment and subsequent re-builds.
- Multi-Diskgroup support for Oracle ASM
- Support for multiplexed Controlfile & REDO logfiles
- Default kernel boot is Unbreakable Enterprise Kernel (UEK3) 3.8.13-55, seamless transition to HVM mode
- Oracle Linux 7, BTRFS & Ksplice Ready!
Have a great week and we'll see you next Friday!

If you missed it yesterday, we did a press release describing the posting of Oracle Linux images on the Docker Hub Registry. If you're already working with Docker or interested in getting started with it, Oracle Linux gives you an extremely solid foundation to build on.
For a bit more on Docker, we did a webcast in November called Building the Modern Cloud-Enabled Data Center, where Docker and other trending topics were discussed. Have a view of the replay.
Also, did you know that you can bookmark tag searches on Oracle blogs? For example, to find posts on our blog about Docker, you'd use this:
Click that link and bookmark it, and you'll always have the complete list of Oracle Linux Blog posts that mention Docker.
Have a great week and we'll see you next Friday!
