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!
