Hi, i am learning RAC now. I am planning to setup a lab environment at home. My plan is running 2 VM on a host PC.
Host PC: Windows 7 + VirtualBox
VM: windows 2008 + Oracle 11gr2
i knew i can setup shared disk in VirtualBox, so i don't need a NAS.
my question is: what's the installation size for the VM (windows 2008 + Oracle 11gr2)? the reason i ask, because I did the math: host is about 30gb, shared disk is about 20gb, if VM is also under 30gb, i can setup the lab on a single 120gb SSD.
Also, how much RAM needed on each node?
is it less disk space\RAM required if i choose OEL + Oracle 11gr2 on the node?
I usually budget 15G per VM, with 1500M RAM. You may find it helpful to create another VDI disc to use as a staging area for the GI and DB software, it will need to be about 6G to store both the ZIPs and the expanded software.
You may need a third VM though (10G disc and 500M RAM is enough) to act as your DHCP and DNS server: I never managed to get the VirtualBox DHCP and DNS services working correctly for GNS.

Should have mentioned, all the above is OEL.
