Was the new database on the same box as the database that is causing the

There are several things that can help:
1 - There is a "default" service based on your "DB_UNIQUE_NAME" that seems to
get enabled for me, that does not show up in the "lsnrctl status services"
command. This has driven me nuts before.
2 - you can try setting "local_listener" on the database. This should resolve
to a TNSNAMES.ORA alias that points to the hostname and port information for
the listener. This may help your database instance "auto register" with the
listener.
3 - i would remove the listener entry that you tried to place in the
listener.ora file, as this should not be needed. The database server process
should register with the listener within a few minutes.
4 - some useful commands if using "spfiles", otherwise you must manually edit
the init.ora file:
sqlplus / as sysdba
show parameter serivice_names
show parameter local_listener
alter system set service_names='newservice' scope = both;
alter system set local_listener='tns_alias' scope = both;
Hope this helps...
