how to control RAM versus "pagefile" on HD

Hi
When working I have 4 or 6 programs running. But only one, a databaseprogram, is
doing any real work (the rest is pictures on very old text and another
databaseprogram which most of the time is just open).
After working for an houer or more doing some lookups on the net and so, the main
databaseprogram starts running sloooooooow. I think it has been mooved from RAM to
the pagefile (what else?)
and it helps shoting it down and restart it.
Now, how do I get that databaseprogram to stay in the RAM ?

Erik,

As far as I recall the only way to keep programs and data in RAM is to keep
accessing them. Once data in RAM has been idle for a certain length of time
(which is not a fixed length of time) the memory manager pages it. If the
data is being accessed frequently enough this cannot happen.

There is no other way that I am aware of to influene what and when data is
written to the pagefile. It is in fact surprisingly difficult to even work
out what proportion of a program's total virtual memory footprint is stored
in physical memory and what has been paged at any given time.
