hi,
1- >
This parameter you need to set init.ora file "LOCAL_LISTENER " so that when the instance starups... the PMON will dynamically registers the Listener..
Added information on 11g is that you got new paramter "DYNAMIC_REGISTRATION_listener_name"
Which enable or disable dynamic registration. When set to on, the listener accepts dynamic registration; when set to off, the listener refuses dynamic registration. Static registrations are not affected.
By Default is "on"
