Kelly Computer Systems used to have RAMDISC/XL, which was part of a
software/hardware (memory board) package they sold.  I'm not sure what
the current status of that offering is.
 
However, <PLUG>, a subset of that functionality is available in the
System Manager's Toolbox from Lund Performance Solutions, in the
program called KLONDIKE.  With KLONDIKE, you can say:
 
   freeze SALES23.PUB.FOO
 
which would bring the entire dataset into memory, and freeze it.
 
(More info at: http://www.allegro.com/toolboxes.html)
 
The Kelly program allowed you to bring in selected ranges of the
dataset (as well as the whole dataset).
 
Finally, if you use KLONDIKE to freeze a file into memory, the freeze
will be forgotten some number of minutes after the last person stops using
the file ... which shouldn't be a problem in your situation.  The Kelly
product avoids that problem, keeping the file (or subset) frozen as long
as you wish.
 
Allegro Consultants wrote both products, and (in theory) have a small
financial interest in them.
