Thanks Roberto,
You have almost made my day :)
Can you clarify to what extent I can "isolate" app instances for each
of my customers?
For example...
Is it feasible to maintain separate "table sets" for 1000s of
customer?
Is it possible for one misbehaving customer "instance" to adversely
affect other customers?
Regards,
rvjcallanan
