Not able to find database connection names in the logon dropdown

I have installed Sql Navigator 4.1 recently for my 10g database. However, I do not see any database connection in the dropdown list we get while logging.

The tnsnames.ora file is in the network/admin folder… I am able to connect to sql plus. I am not able to connect to sql navigator.

Gurus, Please help


I’d suggest installing a later version of SQL Nav - version 5.5, 6.0 or 6.1, even though the latter is still in beta - version 4.x does not support connections to 10g or later:
