I'm trying to connect to Oracle DB using DB Tool, when I run the test it gives me the below error. Listener refused the connection with the following error: ORA-12519, TNS:no appropriate service handler found 66000 What could be the reason ? I did try with some other connection string for same Oracle DB and it worked fine. The issue is specific to 1 set of connection string.
