In trying to setup a new connection in the Database Explorer, I get the following error message, only when clicking the Direct checkbox.

ORA-12545 Connect failed because target host or object does not exist.

If I uncheck the checkbox, it works fine. The SID is filled in with the same SID from my tnsnames file.

Please note that in the server parameter in Direct mode should be filled with the name of machine where Oracle server is installed or its IP address.

I was unable to get the OracleConnection to work with a server name. However, when I used the IP address of the server, it worked fine. Probably something with DNS but I did not investigate further.
