swap size recommendation for large DB server

["Stanley, Jon" <Jon Stanley savvis net>]

I have a relatively large database server (quad Opteron with 32GB RAM).
Oracle is having some type of performance issue on this host.

Oracle support is saying that we need swap that's 2x physical RAM.  With
todays systems that have huge amounts of memory, that's just not
feasible, practical, or desirable from a SA's standpoint.

What I'm looking for is some BCP about how to size swap with large
amounts of RAM.  I know that it doesn't make sense, but I need something
to throw in Oracle's face to say their recommendation is bogus.

BTW, the system isn't even touching swap.
