How to configure listener.ora

[varaprasad_1261]

Hi,

Iam using oracle 9i on windows. when started the listener iam getting the error that "The listener supports no services"

As per the oracle documentation i configured my listener.ora file with values,

newDB = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.46)(PORT = 1521))))

SID_LIST_newDB = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = newDB)(ORACLE_HOME = c:\orahome1)(SID_NAME = newDB)))

When i start the listener i am getting the following message

Is anything wrong in the listener.ora ?

no, your database needs to register itself with the listener (if it is up pmon will do it after a minute or so) there is no need to list databases in listener.ora anymore

(althought some software still reads it)

[lakher]

if protocol is tcp and listener port 1521,the database auto register.

when i give the command, sqlplus "sys/prasad@newDB as sysdba", iam getting the following error

my tnsnames.ora entry is

newDB = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.46)(PORT = 1521)))(CONNECT_DATA = (SID = newDB)(SERVER = DEDICATED)))

when started the listener, iam getting the message
The listener supports no services

I guess this is the root cause of the error.

Is anything wrong with my listener.ora and tnsnames.ora ?

sqlplus "/ as sysdba"

then startup

[ebrian]

How are you starting your listener?

Since you changed the default name of the listener, you'll have to issue:

lsnrctl start newDB

and then try to connect as:

   sqlplus "sys/prasad@newDB as sysdba"

After this, you may want to go into the Windows registry and remove the service that was added for the default listener. You'll have TWO listener entries in the Window's services (one for newDB and one for LISTENER), since you are using newDB you'll want to remove the LISTENER entry.

Thanks ebrian,

I started using the commad "lsnrct start newDB".
It started the listener successfully.

In the lsnrctl commad output i found an error

Failed to open service , error 1060

This occured for the first time when i start newDB listener.

Is there is any method to register a service prior to start of the listener (in windows and Unix flavoured operating systems).

With regards,
Prasad.

Is it a good practice to have listener entry for every sid ?
Or to use default Listener to register every SID ?

one listener per machine
