Re: laptop configuration

Paging won't be a huge problem as long as you do this:
1) use 900MB vm's (two of these fit easily in 4G of physical memory,
bigger VMs might start swapping)
2) make sure to unlock the CRS memory inside the VMs - this releases
over a GB of physical mem which doesn't need to be locked in a sandbox,
and indeed it's the only way to have a usable environment on a lower-end
laptop
this script will unlock the CRS memory in 11gR2:
