ORA-12514: TNS:listener does not currently know of service requested in connect

*** after you changed the default listener port number, the database instances will not be able to register themselves with this new listener. ***

Solve:

1. modified LOCAL_LISTENER parameter to point to the address of the local listener.

SQL> ALTER SYSTEM SET LOCAL_LISTENER="(address=(protocol=TCP)(host=localhost)(port=1529))" SCOPE=BOTH;
System altered.

2. Edited tnsnames.ora file (for alias) in the same location as listener.ora file and then modified LOCAL_LISTENER parameter to point to that alias.
