[OFBiz] Users - RMI / database shared / disconnected operation / sync

[Si Chen]

The former is in entityengine.xml.  The second is in general.properties.

In my experience, each instance will do its own caching.  They will run 
as completely independent instances.

As for RMI synchronization, try looking in the entityext component and 
the services.xml.  They have an rmi service at the bottom for 
synchronizing entities between two ofbiz instances.  Setting up ofbiz 
for remote synchronization is pretty easy--you just have to put in the 
ip address of the remote machine, and it will go look for it.  The 
problems I've had mostly relate to RMI itself.  Also, make sure both 
instances have the same admin username/password.

Good luck!
