What a really low grade tutorial, the authors didn't care at all about the quality of the code they are writing. No arguments checking, the database connection is not even closed, I know it is supposed to be a starting point but still so bad.... I'd expect more from Oracle....

In my case, its showing an error. ORA-12541 TNS:No listener. I'm also confused whether to choose ODP.NET Managed Driver or Unmanaged Driver. I've installed all the components of ODAC with ODP from here - http://www.oracle.com/technetwork/topics/dotnet/index-085095.html I can't find the Configuration Tools to create a listener. What is a listener? I don't understand. I'm a beginner .NET environment and I'm stuck. Help me out.
