You are effectively operating in a cluster, where your workstations are 
also cluster nodes:

The other option, which tends to be the easiest, is
to use a per-broker
cache (non-distributed) and optimistic transactions,
in which case you
acknowledge that data in cache for the lifetime of
one broker (usually
short depending on how you use it) may be dirty if
ti is in contention.
This doesn't work for highly contentious data,
however.

Hi All,
I just learned OJB.
I have written one application in OJB.
My application is client-server application in
which
client and server are on different machines and
using
same databse which may be on third machine.
Right now i have one query.
server stores some java object in databse using
PersistaceBroker APIs. Client retrives these
object
on its machine using same i.e. OJB
Now if any object is updated by server which is in
client object cache How can we update client
object
cache when server updates the object in database.
Because I think server cache and client cache are
different.
I need this very urgent.
Thanks in advance
Amol Pophale.
