Friday Spotlight: Software updates, LinuxCon, and more!

Happy Friday!

It's been a busy period here in the Oracle Linux team, so I thought I'd do a highlight post with links to some of the big things that are happening:

- LinuxCon North America starts in just 10 days, and Oracle is a sponsor. The conference features a keynote by Oracle Senior Vice President Linux and Virtualization Wim Coekaerts. If you're there, you don't want to miss it.

- Speaking of Wim and LinuxCon, there is a short video to give you a peek into what Wim will be talking about.

- We released Oracle Linux 6.7.

- We released Unbreakable Enterprise Kernel Release 3 Quarterly Update 6.

There's a lot of other great stuff going on, too, from Oracle Private Cloud Appliance training, to Oracle looking for people interested in working to design and develop technical training, and a new linux.com article on sysadmin job interview questions, featuring thoughts from Oracle Linux product management.

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

FRIDAY SPOTLIGHT: Getting Started with Docker on Oracle Linux

Happy Friday everyone! 

We have a great technical article for you this Friday.  In this article, you learn how to customize a Docker container image and use it to instantiate application instances across different Linux servers. This article describes how to create a Dockerfile, how to allocate runtime resources to containers, and how to establish a communication channel between two containers (for example, between web server and database containers). 

Ginny Henningsen quotes "Docker is exciting because it can easily capture a full application environment into a virtual container that can be deployed across different Linux servers. System administrators and software developers are learning that Docker can help them deploy application images on Linux quickly, reliably, and consistently—without dependency and portability problems that can inject delays into planned deployment schedules. Docker containers can define an application and its dependencies using a small text file (a Dockerfile) that can be moved to different Linux releases and quickly rebuilt, simplifying application portability. In this way, "Dockerized" applications are easily migrated to different Linux servers where they can execute on bare metal, in a virtual machine, or on Linux instances in the cloud. "

As shown in Figure 1, Docker containers consume fewer resources than "heavyweight" hypervisor-based solutions. Hypervisor-based solutions host a full-blown operating system instance in each virtual machine guest, but this also allows them to support different operating systems. (Oracle VM, for example, can host Oracle Linux, Oracle Solaris, and Microsoft Windows in virtual machines.)

End-to-end Data Protection Using Oracle Linux with the ETERNUS DX S3 series and Emulex HBA

As demand for data protection has grown in recent years, ensuring the integrity of the customer's data is a very important task. To carry out this task, data protection is not only required for the storage system but the entire system.

This White Paper from Fujitsu, an Oracle Diamond Partner, explains how data protection can be implemented for the entire system using T10 Protection Information (T10 PI) that comes with the Oracle Linux with Unbreakable Enterprise Kernel (UEK), the ETERNUS DX S3 series, and Emulex HBA.

The T10 PI and DIX functions enable data protection for the entire system including data write processes from applications to disk drives. Data protection for the entire system can improve system reliability by protecting the system from damaged or inconsistent data to minimize downtime and reduce end-user maintenance cost.

Read more about End-to-end Data Protection Using Oracle Linux with the ETERNUS DX S3 series and Emulex HBA.

We would like to highlight another whitepaper published by Fujitsu in January about End-to-end Data Protection Using Oracle Linux with the ETERNUS DX S3 series and Qlogic HBA

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!
