ODP.NET

I am trying a small test project with the new ODP.NET Managed Driver Beta 2.

I have installed using configure.bat and I am trying to connect to an Oracle 10.1 instance.

On the call to OracleConnection.Open() the following exception is thrown:

"ORA-03111: Break received on communication channel"

StackTrace:

   at Oracle.ManagedDataAccess.Client.OracleException.HandleError(OracleTraceLevel level, OracleTraceTag tag, Exception ex)
   at OracleInternal.ServiceObjects.OracleConnectionImpl.DoDataTypeNegotiation()
   at OracleInternal.ServiceObjects.OracleConnectionImpl.Connect(ConnectionString cs, Boolean bOpenEndUserSession)

   at Oracle.ManagedDataAccess.Client.OracleConnection.Open()
   at ConsoleApplication5.Program.Main(String[] args)

Testing program source:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Oracle.ManagedDataAccess.Client;

namespace ConsoleApplication5
{
    class Program
    {
        static void Main(string[] args)
        {
            string connstring = "User Id=scott;Password=tiger;Data Source=testserver:1521/testservice";
            var conn = new Oracle.ManagedDataAccess.Client.OracleConnection(connstring);
            conn.Open();
            conn.Close();
            Console.ReadLine();
        }
    }
}

Server version:

scott@TESTSERVICE(196)> select * from v$version
