In which situation would you use static database registration for a listener?
A.
When DBAs need to connect remotely to start up the database instance
B.
When users need to connect the database instance using the host naming method
C.
When multiple databases are to be registered with the listener
D.
When the database instance that is to be registered with the listener is configured in
shared server mode
Explanation:
Static database service Registration
A hard-coded listener.ora with a list of instances and/or database service names it will serve are and remain registered in the listener.ora regardless of whether these databases are up or not. This is a necessity to remotely startup the database such as during RMAN duplication, otherwise if a database isn’t up – it wouldn’t be registered, hence you would not be able to start it.
