Hi I run both em12c and 2 node RAC in Virtual Box, though I built them myself. To my disappointment I've found that em12c really does want the 2 cores and 6gb of RAM advertised at http://docs.oracle.com/cd/E24628_01/install.121/e22624/preinstall_req_hw.htm#BACDDAAC. In addition I try and give each of my RAC vms at least 2 and pref 4gb ram (so that the db isn't pathetically small). There is a script that the RAC ATTACK guys http://www.ardentperf.com/pub/schneider-RAC11g-lab.pdf have put together that can claim memory back from the RAC nodes. I have 16gb of RAM in my laptop though so it's mostly processing power that limits me. I suspect you'll run into memory shortage with 8gb ram if you want to run all 3 VMs together.

VMware Server/Player isn't really the same product as the enterprise virtualisation product so I don't really think it makes that much odds. > Q7) Is it legal to produce, and has anyone released, various Oracle images > for self-education / training purposes that will run on VMWare Player? > In a word, No. I don't believe it is even legal to do this with the free XE version, though I can't see Oracle would care in practice.
