	| dear all, 
 i installed oracle 10g (10.2.0.1) and patched it to 10.2.0.4. i created a database , set up the listener and oracle service instance but i m facing the folling problem. I succeed to shutdown immediate the database through sqlplus but when trying to start it up i get the following error.
 
 ORA-12514: TNS:listener does not currently know of service requested
 
 replacing in service with the oracle_sid i get the message
 
 ORA-12505: TNS:listener does not currently know of SID given in connect descriptor
 
 i tried to change either SID to database name and vice versa but still get the same. howevr restarting the service brings everything back to normal.
 
 any suggestion pls??

	| Hi,
 
 1. Your DB should be up and running.
 2. Check your tnsnames properly what you are specifying there.
 3. Your SID and Db_name can be different.
 4. Do you have two DB running in that box if yes ,most probably you would have independent listeners . List lsnrctl services for each listener and check if services are getting mismatched with each other.
 
 Regards
 
 Bala
