Thanks for your reply Aaron.
I run upwards of 5 or 6 tomcat instances running
different applications each using JCS on a single box.
If they are using distribution plugins that require
them to bind to aprticular port, then I just configure
them to listen to different ports.
Just to confirm. In your system, do all the (5 or 6) tomcat instances
use precisely the same cache.ccf? In other words, are they using
exactly the same cache on disk, and exactly the same cached data? That
is what I want to do - well, maybe not quite 5 or 6 instances, but at
least 2 or 3. If they do, I'm wondering how you get all the instances
to synch the cache data and key index across the instance's in-memory
cache - or, does it just work?

Couple of questions:
1) I suppose that only one application instance
at a time, on a
particular computer, can reliably use a jcs region,
right?
No. I run upwards of 5 or 6 tomcat instances running
different applications each using JCS on a single box.

them to bind to aprticular port, then I just configure

2) is there any code to synch access to the same
cache region within
2 or more apps running on the same machine?
Yes. Just have them listen to different ports if use
the tcp lateral or the rmi remote cache.
3) when the application ends, I call
JCS.dispose() which takes
several seconds to complete, presumably defragging
the cache data - is
there a way to prevent defragging upon dispose?
Would it be advisable
to do that?
No you can't stop it right now, but you can set a max
wait time. The remote cache client does not shutdown
properly, forcing you to kill the application.
4) correspondingly, is there a way to flush
memory to disk every now
and then, not necessarily defragging?
Yes, there is a brand new method that will do this.
You can tell it the number to free. You can pass it
the size. It's called freeMemoryElements.
That'll will do for starters I think - thanks in
advance. j
