Join us in this live webcast to learn how Oracle’s latest Engineered System simplifies your journey to virtualization and cloud. Live webcast August 13th, 2013, 10am PT/1pm ET.
Happy Friday! This week's tip is on Oracle VM Server for SPARC, and it's just a quick pointer to a really great paper.
A common scenario for Oracle Database users is to run the database on Oracle Solaris and use Oracle VM Server for SPARC as the virtualization technology. Of course, one of the great benefits of virtualization is portability, but how do you move an instance of the database to take a physical server offline (to add more memory, for example)? The Oracle white paper Increasing Application Availability by Using the Oracle VM Server for SPARC Live Migration Feature: An Oracle Database Example will tell you the hows and whys of this important process.
See you all next week!

Happy Friday! This week we're talking about tips and tricks for fullscreen mode in Oracle VM VirtualBox.
I use typically Oracle VM VirtualBox on the Mac and I find it very convenient to set my virtual machines to run in full screen mode in a separate Space. I'm using Mountain Lion, but this should be similar for Mavericks (I think, I haven't used it yet!).
To go full screen, first, launch your virtual machine. You can then use the host key (command on the Mac) and F to go full screen. You can also switch to full screen in the menu bar with View->Switch to Fullscreen. There's also a useful option there that will set the resolution of the guest OS to match your monitor, and that is View->Auto-resize Guest Display.
In the Mac on Mountain Lion (and perhaps on Lion, I don't have it around to confirm), this full screen VM will have its own Space. That means you can do the three finger quick swipe left or right to switch between your local Mac OS spaces and your full screen virtual machine. It's extremely cool. Another thing I do to make moving between the virtual machine and the Mac OS desktop even easier is to go into Mission Control (three finger swipe up on a trackpad, or open the app itself) and drag the Space with the VM in it all the way to one side or the other of your Spaces - I prefer the right side. Then in the Mission Control System Preference, turn off "Automatically rearrange spaces based on most recent use." What this does is ensure that you can quickly three finger swipe all the way left or all the way right to get either a Mac OS desktop or your fullscreen VM.
One other quick tip. If you don't find yourself needing the items in the mini-toolbar, you can hide it by clicking on the VM in Oracle VM VirtualBox manager, and then clicking on "Settings" in the toolbar. In the General tab of that dialog box, click Advanced and then uncheck Mini ToolBar: Show In Fullscreen/Seamless. The only thing I use the Mini Toolbar for on a regular basis is suspending the VM, which you can do just as easily by press the host key (again, command on the Mac) and Q. You'll get the same dialog that you get when pressing X on the mini toolbar.
This week we're talking about 3D graphics performance with Oracle VM VirtualBox.
Our own Fat Bloke just published a blog that describes how to make sure you get the most out of Ubuntu's GUI using the OpenGL acceleration in VirtualBox. In the picture below, you'll see all the shiny Chromium renderers in use:
We'll see you next week!
It’s always nice to start off the new fiscal year with some good news and this year it comes at the hands of Francisco Munoz Alvarez, a seasoned expert, and Oracle ACE Director, in the Oracle community. With the help from his employer Revera Limited, a provider of utility computing infrastructure and enterprise data management solutions, Francisco recently compared the performance of Oracle Database workloads running in a bare metal environment versus a virtualized environment (Oracle VM and others). The results were quite telling!
Here’s what they found:
• Oracle VM is the better virtualization technology to run Oracle Databases
• Oracle VM makes a better use of all available resources
• Oracle VM is more scalable and stable for Oracle Databases
• Oracle VM allows better consolidation of loads in a virtual environment
• Oracle VM uses less CPU than non-Oracle virtualization technologies
Francisco and his team also found that without Oracle VM, organizations can have a full physical server (bare metal) with underutilized resources. However, by using Oracle VM organizations will be able to virtualize it to host many Oracle Databases, without sacrificing performance and can make better use of all available database licenses. They also noted a few bonus results including the fact that Oracle VM allows extra high availability and is fully certified and supported by Oracle.
I think Francisco touched on something very important in his report when he concluded by saying, “Many companies around the world are afraid to use virtualization for production databases, as per our experience we can say that it is only a myth. Revera have many production databases running on Oracle VM without any unsatisfied client.”
It’s time to overcome the fear. As Francisco’s results show, Oracle VM delivers a great solution for enterprise environments!
