One of the biggest obstacles preventing people from setting up test RAC environments is the requirement for shared storage. Oracle Database 11g Release 2 RAC On Windows 2008 Using VirtualBox.Oracle Database 11g Release 2 RAC On Oracle Linux 5.8 Using VirtualBox.This article describes the installation of Oracle Database 11g release 2 (11.2.0.3 64-bit) RAC on Linux (Oracle Linux 6.3 64-bit) using VirtualBox (4.2.6) with no additional shared disk devices. Only if you remove all the Hyper-V stuff from Windows does Virtualbox use its own virtualization engine, see the icon below in the image.Home » Articles » 11g » Here Oracle Database 11g Release 2 (11.2.0.3) RAC On Oracle Linux 6.3 Using VirtualBox If this is visible, Virtualbox uses components from Hyper-V, with which, for example, the Windows Sandbox also runs. If you take a closer look at the virtual machine window, you might see a turtle icon in the lower right corner. Oracle did not place this notice for fun (c) PCtipp.chĪlthough my accusation of “no indication” needs to be put into perspective a little. Less nice, however, that Virtualbox never displayed a corresponding message while I was struggling with the virtual machines. The briefest text in the manual is accompanied by a note that (translated) reads roughly: When using this feature, some hosts experience significant virtual machine performance degradation. And this “experimental” is to be taken literally. Half a weekend went by before I came across an inconspicuous hint in the Virtualbox forum and in the online manual: Virtualbox also supports the Hyper-V virtualization engine included in Windows 11 (and probably Windows 10 as well) «experimentally».

If it ran through once after hours, other symptoms became noticeable in addition to the underground performance: sudden reboots of the VM for no apparent reason and increasing time delays in the system clock. That should easily be enough! And yet: Whether I tried it with Windows 10 or 11 in the VM, the installation was excruciatingly slow. Thanks to a graphics card suitable for gaming, I was also able to activate 3D acceleration and allocate 256 MB of graphics memory. I assigned 8 GB of RAM and 4 CPU cores to the virtual machines.
