recommended swap size

I have always used the rule of thumb to double system memory for swap,
but now I'm installing a machine that will be used for Oracle with 8
gig's of memory. I have a hard time thinking that the OS will know what
to do with a 16gig swap file. Can others let me know what they are
doing for swap with machines with larger amounts of physical memory?

Thanks in advance.
