Oracle.DataAccess 4.112.2.0 and EnterpriseLibrary 5.0.414.0

Question

Hello,
I use ODP.NET and version 4.1 of the Enterprise Library, vs 2008. And all is OK.
Now, migrate using ODP.NET Oracle.DataAccess 4.112.2.0 and version 5.0.414.0 of the Enterprise Library, vs 2010, .net 4.0.
Following a recent upgrade from version 4.1 to 5.0 of the Enterprise Library, once we get the following error:
"The type Database cannot be constructed. You must configure the container to supply this value."
Microsoft.Practices.ServiceLocation.ActivationException: Activation error occured while trying to get instance of type Database, key "ConnectionStrings.Oracle.xxx" ---> Microsoft.Practices.Unity.ResolutionFailedException: Resolution of the dependency failed, type = "Microsoft.Practices.EnterpriseLibrary.Data.Database", name = "ConnectionStrings.Oracle.xxx".
Exception occurred while: while resolving.
Exception is: InvalidOperationException - The type Database cannot be constructed. You must configure the container to supply this value.

any solution about it ??
my config

My Code
var key = "ConnectionStrings.Oracle.xxx";
Database db = Microsoft.Practices.EnterpriseLibrary.Common.Configuration.EnterpriseLibraryContainer.Current.GetInstance<Database>(key); //~(EntLib 5 recommended)
using (DbCommand cm = db.GetStoredProcCommand("TBL_FRKDATA.TBL_FRKDATA_FND_ALL"))
cm.Parameters.Add(CreateCursorParameter("P_REFCURSOR"));
// Using "using" will cause both the DataReader and connection to be
// closed. (ExecuteReader will close the connection when the
// DataReader is closed.)
using (IDataReader dataReader = db.ExecuteReader(cm))
while (dataReader.Read())
builder.Add(dataReader);
return builder.EntityList;

Update
this code works for me:
[TestMethod]

var key = "ConnectionStrings.Oracle.xxx";
string connectionString = ConfigurationManager.ConnectionStrings[key].ConnectionString;
string providerName = ConfigurationManager.ConnectionStrings[key].ProviderName;
//Database db = Microsoft.Practices.EnterpriseLibrary.Common.Configuration.EnterpriseLibraryContainer.Current.GetInstance<Database>(key);
TestContext.WriteLine("connectionString: " + connectionString);
TestContext.WriteLine("providerName: " + providerName);
DbProviderFactory factory = DbProviderFactories.GetFactory(providerName);
using (DbConnection connection = factory.CreateConnection())
connection.ConnectionString = connectionString;
connection.Open();
TestContext.WriteLine("Estado Conexión: " + connection.State);
connection.Close();
