Hi

I am trying to connect to remote oracle database from windows (using sqlplus and TOAD) that had a cname change, the oracle that remote database was installed has changed from one unix machine to another and nothing else changed - after this change both database and listener was up and the remote team was saying no issues connecting to their database, but when I try to connect using database link I get - ORA-12514: TNS:listener does not currently know of service requested in connect descriptor. I asked them to stop and restart the listener many times and also I could tnsping from windows and also can connect direcly in sqlplus or toad using the user id and password that I used in database link, but the database link alone does not work - any clues?

Hi mahjag,

Did you change your TNSNAMES to be able to connect to where the new database is?  If so, was the TNSNAMES for the database where the dblink is from also changed?
