Actually, all you need to do is _install_ it on subject file system.
There's nothing on the implementation side that needs to be done for it.

Mark,
That's an excellent suggestion, inasmuch as we have a couple dozen of these
servers running and, if nothing else, sharing code could reduce overall
demand for memory. Obviously, the bigger win would be if this is the code
that is actually being paged in and causing the delays, since by sharing it
would be more likely to be in storage already.
The larger problem is going to be getting buy-in from the app owner to
implement such a thing.
Best regards,
Mark
