Maximum swap partition sizes

[Simper, Brian D]

Does anyone know what the maximum recommended size that swap partitions can
be?  I was looking in an Oracle install manual and it wanted as much as 2GB
which seems like extreme overkill for a Linux server.  In addition, I had
heard that Linux could handle a maximum of 1GB in the swap partition but I
haven't seen any documentation on this.  Does anyone know conclusively how
big a swap partition can be under Linux?

Thanks,
