Problem in accessing second database instance on same host (ORA-12514)

Question

Hi,
I had a database ICMDB installed on my machine. After that i created a second database instance (Service name: BI_APPS) using DBCA on the same machine. Using NETCA i also created a new listener OracleOraDb11g_home1TNSListenerBI_APPS_LISTENER on port 1522 on my machine. Then i configured this listener to listen for connections to service BI_APPS by adding the following to my tnsnames.ora:
BI_APPS_LISTENER =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.109)(PORT = 1522))
Then i changed the port in my tns entry for BI_APPS to 1522 as follows:
BI_APPS =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.109)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = BI_APPS)
I then restarted the following services:
OracleOraDb11g_home1TNSListener
OracleServiceBIAPPS
OracleOraDb11g_home1TNSListenerBI_APPS_LISTENER
After this, when i try to access my first DB ICMDB via toad, the connection is successful. However, when i try to access the service BI_APPS i get the following error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
What am i doing wrong? Here is the content of my files:

Hi Ed,
I understand your point, however whenever i have tried to use the same listener to access my second instance, this is the error i have always received:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
That does not indicate you need a second listener.
And, after deleting the listener.ora file ,if i try the the command lsnrctl start, i get the error:
ORA-12560: TNS:protocol adapter error
Hence i restored the files. What do i do?
I've never experienced a 12560 trying to start a listener.  I'll need to see if I can create a test system on Windows and try to recreate.  Will be a good subject for my blog, that has been too long with no new content.
Since this is windows, I'd first check that the Windows service for the listenr is started.
Whatever, multiple listeners is NOT the solution.
