Re: Dedicated connections on MTS server

I'm fighting this same problem, but in reverse. I'm trying to get all my folks using DEDICATED connections.

Simply put on my server the listener uses port 1521 for MTS/shared connections. It uses port1529 for DEDICATED connections. The TNSNAMES.ORA file on each client determines which port is used.

If you simply & REALLY want to preclude your users from connecting as DEDICATED session, then simply remove that port from the listener.ora file & bounce the listener. If/when the listener no longer accepts connections for the dedicated port, all your users will be forced to use MTS.

FWIW - When I switched from MTS to DEDICATED my nightly batch jobs went from 5 hours of run time to about ONE hour of runtime.
