I am having a problem connecting to an oracle database using oracle8 client.
It is installed on windows7.
I have the same tnsnames.ora and sqlnet.ora files as everyone else here.
The only difference is that everyone else is on XP and they are working fine, no problems.
The client on Windows7 gets the error: ORA-12203: TNS:unable to connect to destination.
I have also tried to connect to oracle from an access database on the same windows7 pc with an odbc and I get the same error as above.
Is the database host identified by the DNS name in the TNSNAMES file? If yes, I would give it a try using the actual IP address for the host, and not the DNS name - it could be a DNS issue which will be avoided by using IP address.
Question... why Oracle 8 client? What version is the target database?
