To disable Redrive, you must disable logons from the Supervisor window of Database Window (DBW) or similar console subsystem interface, such as cnsterm. Ensure that no sessions are logged on before setting RedriveProtection to 0.
The Redrive feature can be enabled and disabled at the session level using the REDRIVE query band and by means of the TDWM.redrive table, which can determine if redrive is used at the user, account, or profile level.
