Friday Spotlight: Oracle Linux and Database Smart Flash Cache

Happy Friday!

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.

I highly recommend checking out Wim's blog entry on this fantastic feature, and there is also an in-depth white paper you can have a read through for even more info.

Have a great week!

Introduction to Using Oracle's Unbreakable Linux Network

Oracle's Unbreakable Linux Network (ULN) is a comprehensive resource for Oracle Unbreakable Linux support subscribers. ULN offers Linux software patches, updates and fixes, along with information on the yum program and support policies. Support subscribers can also download useful extra packages not included in the original distribution.

Watch this series of 3 videos Introduction to Using Oracle's Unbreakable Linux Network to learn how to:

  • Register an Oracle Linux system with the Unbreakable Linux Network (ULN)
  • Use Oracle's ULN web interface
  • Use the yum utility to install updates from ULN

This is one of the many topics you can learn more about in the Oracle Linux System Administration curriculum.

Friday Spotlight: The Oracle Learning Library

Happy Friday!

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!

Friday Spotlight: New Oracle VM Templates for Oracle Database

Happy Friday!

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!

You can read Honglin's full post over at the Oracle Virtualization Blog, or you can go directly to the Oracle VM Templates for Oracle Database page.

Have a great week and we'll see you next Friday!

Friday Spotlight: Docker!

Happy 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:

https://blogs.oracle.com/linux/tags/docker

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!

I wanted to quickly draw your attention today to a couple of updates. First, Spacewalk 2.2 for Oracle Linux is available on our public yum server. We have also published the Release Notes, including upgrade instructions from Spacewalk 2.0.

If you're interested in Spacewalk, you might enjoy a webcast we did in November that goes into a lot of detail on using Oracle Linux and Spacewalk together. You can watch that webcast on-demand.

And second, RPMs for the Oracle Instant Client are now available on Unbreakable Linux Network.

Friday Spotlight: Oracle Linux and The Next Generation of Oracle Engineered Systems

Happy Friday! This has been exciting week for the Oracle Linux and Oracle VM teams here at Oracle, with our products prominently featured in The Next Generation of Oracle Engineered Systems event on Wednesday. If you missed the live event, take some time to watch the videos in the archive.

In addition to the Larry Ellison announcement video--which is highly recommended!--there is in-depth Oracle Linux content in two of the other videos. First, the panel discussion video (video #3 in the list on the archive page) features several Oracle executives, including Oracle Senior Vice President, Linux and Virtualization, Wim Coekaerts. And last, in the Go Deep section Wim goes into detail on Oracle Linux and how it can benefit your data center.

We'll covered Engineered Systems many times on the blog, but we'll get into some detail on these new systems and Oracle Linux in future entries. In the meantime, clicking any of the pictures in this post will take you to the replay, it's exciting stuff! 

We'll see you next week!

Friday Spotlight: Unbreakable Enterprise Kernel Release 3 Quarterly Update 4

Happy Friday!

The big news this week was the release of Unbreakable Enterprise Kernel Release 3 Quarterly Update 4. If you missed our blog about it on Monday, there are a number of interesting improvements in this release. And a really nice aspect of the Oracle Linux architecture is that you can use the Unbreakable Enterprise Kernel on either Oracle Linux 6 or Oracle Linux 7. This gives you a tremendous amount of flexibility by not forcing you to upgrade the entire OS to get these improvements.

Read the blog for more info on this release, and we'll see you next week!
