The problem is accessing the instance 'conf' from client computer 1 using SQL*Plus. I can access the instance on the server using SQL*Plus. Also, I can access the instance from client computer 2. However, from client 1, I'm getting the following message:
% sqlplus username/password@conf SQL*Plus: Release 10.1.0.3.0 - Production on Wed May 4 23:03:04 2005 Copyright (c) 1982, 2004, Oracle. All rights reserved. ERROR: ORA-12514: TNS:listener does not currently know of service requested in connect descriptorPlease help me to resolve the above problem.
To verify if the service name in tnsnames.ora matches what is registered with the listener, do the following:
- Log into the database server.
- At the DOS prompt, run the listener control utility
- Set the display mode
LSNRCTL> set displaymode verbose
- Display the services
Check that the service name registered with the listener matches what you have defined in the tnsnames.ora file of the client.
