*Does anyone here know what he is talking about?* Possibly not your DW architect :-)

Oracle has memory allocations for many things, for temporary workareas, for commonly accessed data etc...

So if you've got

1. an abundance of spare RAM floating around, and
2. evidence that supports you needing more for Oracle activities

you're most probably better off setting the Oracle parameters to consume that RAM rather than something such as ram disk etc...
