Normally, yes. But the V7 Multi-Threaded Server sets up a number of dispatchers, each of which can handle a number of users.

Depends on memory size. No fixed limit as far as I know.

If using MTS, each dispatcher can only handle a small number of concurrent users, but Oracle can be set up to dynamically create dispatchers up to any maximum.

Would've thought it was much the same as moving from one physical machine to another. Set up a parallel Server & Import the data.
