ORA-12514: TNS:listener could not Find
I have already created Listener, DataBase, User.
I also have checked the tnslistner.ora , names.ora & other files.
They are correct.
tnsping is also working.
I don't find what is problem . plz help me.
Exact Error Is:
ORA-12514: TNS:listener could not resolve SERVICE_NAME given in connect descriptor
youa re trying to connect to a service which the listener doesnt know about.
So yuo tnsnames / listener files are not correct are they?
