Hi,
I have been trying to connect to Oracle database in my codes. I have tried using OdbcConnection and OleDbconnection. But both did not allowed me to connect to the database. The database, testDb, can be accessed using SQL plus as well as the SQL developer. I even tested the connection successful using ODBC data source administrator.
the following is my code for the connection string:
OdbcConnection connectionString = "Driver={Oracle ODBC Driver};Server=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP )(HOST=127.0.0.1)(PORT=1521))(CONNECT_DATA=(SID=Te stDb)));Uid=scott;Pwd=password;";
whenever localhost (127.0.0.1) is used, this means that no remote client can ever connect to this system
The problem involves ODBC configuration & has nothing to do with Oracle.
