What is it with virtualization? It’s similar to people mislay their brain as shortly as they listen to the word. we get the lot of questions about practical RAC installations as well as the immeasurable infancy of problems have been due to people perplexing to run them upon the horde which can’t cut it.
- When we insist we need 3-4G RAM for any VM node in the VirtualBox RAC installation, would we cruise it essential to try as well as set up the 3 node practical RAC upon the horde with 8G RAM? Do the maths. If we have been attempting the practical 11.2 designation with reduction than 3G RAM per node as well as we have problems, don’t come asking me since we will be out.
- Do we unequivocally design hoop speed to be great when we put 8 practical disks upon to the complement hoop upon the horde machine? Do we consider practical disks magically run exclusively of the hosts hoop subsystem?

Follow the steps, or do it your own approach as well as don’t censure me if it doesn’t work.
- Use the same program we list in the installation. Don’t only pretence which if it functions excellent with OL 5.x it’s starting to work unvaried upon OL6, SUSE x.x or Ubuntu (Lethargic Leaper) etc. If we wish to try with opposite distributions that’s fine, though I’m substantially not starting to be equates to to assistance we since if there isn’t an designation beam for it upon my site, it substantially equates to I’ve not finished it.
- If it is the initial Oracle designation you’ve ever done, don’t begin by perplexing to implement the practical RAC. Learn to travel prior to we try running…
