Question: What is a the local_listener
parameter and and how does it differ from an ordinary listener?
When do I need to specify a local listener in my spfile?
Answer: A local listener is specified in your
pfile/spfile startup deck when you database an instance with
multiple listeners.
The local_listener init.ora parameter specifies a
network name that resolves to an address or address list of Oracle
Net local listeners and it is used used ONLY when you have multiple
listeners that are running on the same machine as this instance.
The local_listener service name, address or address list
is must be specified in the tnsnames.ora file or you will get an
ORA-00119 error.
