Dear Prasanna.N,
First of all, please see the following error code;
Error 12514
http://ora-12514.ora-code.com/
ORA-12514:
TNS:listener does not currently know of service requested in connect descriptor
Cause: The listener received a request to establish a connection to a database or other service.
The connect descriptor received by the listener specified a service name for a service (usually a database service) that either has not yet dynamically registered with the listener or has not been statically configured for the listener.
This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener.
Action:      
- Wait a moment and try to connect a second time.
- Check which services are currently known by the listener by executing: lsnrctl services <listener name>
- Check that the SERVICE_NAME parameter in the connect descriptor of the net service name used specifies a service known by the listener.
- If an easy connect naming connect identifier was used, check that the service name specified is a service known by the listener.
- Check for an event in the listener.log file.This is purely a connection problem and you can also use the +"tnsping"+ to see whether the Oracle can resolve the naming service or not. Use the naming service for the tnsping: iasdb_XPT.ind.rsa-ins.com
Fix that problem and edit the tnsnames.ora file and see the results again. You may need to check the alert.log and the listener.log files for further informational messages.
Hope That Helps.
