Note:

LOCAL_LISTENER

Property	Description
Parameter type	String
Syntax	LOCAL_LISTENER =network_name
Default value	(ADDRESS = (PROTOCOL=TCP)(HOST=hostname)(PORT=1521))WherehostnameIs the network name of the local host.
Modifiable	ALTER SYSTEM
Basic	No

LOCAL_LISTENERSpecifies a network name that resolves to an address or address list of Oracle Net local listeners (that is, listeners that are running on the same machine as this instance ). the address or address list is specified inTNSNAMES.ORAFile or other address repository as configured for your system.

 

REMOTE_LISTENER

Property	Description
Parameter type	String
Syntax	REMOTE_LISTENER =network_name
Default value	There is no default value.
Modifiable	ALTER SYSTEM
Basic	Yes

REMOTE_LISTENERSpecifies a network name that resolves to an address or address list of Oracle Net remote listeners (that is, listeners that are not running on the same machine as this instance ). the address or address list is specified inTNSNAMES.ORAFile or other address repository as configured for your system.

That is to say, local_listener is the local listener of a single host server, and remote_listener is the listener parameter of the oracle network remote listener, that is, scan vip.
