Ross,
I'm not sure why it is being done. We had an audit of
our systems done by IBM people and that's one of their
recommendations. I think their logic is "you hit ratio
is pretty high - 99% - so you can do with less
memory".
This server is not a dedicated Oracle server, we are
running another application (SAS) on it.
I have been running sar -wpr to get info on paging,
swapping and unused memory. Does this make sense to
you?
thank you
Gene
