Problems Connecting To Oracle Follow
I keep getting ORA-12660 while trying to connect to my remote oracle instance. Using the exact same TNS data connecting is successful with Sql Developer, so I'm a bit confused.
Originally I tried to use the Microsoft ODB but that caused ORA-12504 (SERVICE_NAME not in CONNECT_DATA even though the SID is there). No configurations on sqlnet have any effect on this. Interestingly I noticed that if you use Connection Identifier (which has the exact same data as in tnsnames.ora for the server) it fails too.
