Actually, I think Windows probably does dynamically shrink it's physical memory
to accomodate the need of it's apps (Oracle in this case). SQL Server does the
same thing - it will take as much memory as it can get by default and will
automatically shrink if Windows tells it to. Memory management is very dynamic
with Windows, but the main problem I've seen with memory on windows is that
memory isn't freed cleanly when processes are killed or terminate abnormally.

I've noticed (haven't precisely measured/tested yet) that given a machine
running windows that has 2 GB of memory and an Oracle database (9.2.0.5 in my
case) with an SGA of 250 MB and you increase your db_cache_size by 200 MB, you
get 150 to 200 MBs of additional pagefile use and real physical memory use only
increases slightly, 50 MB or less. Now maybe, just maybe, Windows is
dynamically reducing it's physical memory use to accomodate Oracle's need for
more, but I seriously doubt that.
