ODP.NET

I am trying to do a straight replace of the DataAccess Client.  I updated my connection string to be   <add name="Oracle" connectionString="Data Source=oracle;User Id=Scott;Password=Tiger;" />.  I set my "oracle.manageddataaccess.client" section to have a dataSource of :

        <dataSource alias="oracle" descriptor="(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=myhost)(PORT = 1111))(CONNECT_DATA=(SERVICE_NAME=MYORACLE)(SERVER = DEDICATED))" />

I run a query that gets executes a proc in a package as follows:

const string query = "select * from table(MYPACKAGE.get_records())";

                var retVal = new DataSet();

                _orComm = new OracleCommand(query, _orConn);

                var oDA = new OracleDataAdapter(_orComm);

                _orComm.CommandType = CommandType.Text;

                _orComm.CommandTimeout = CommandTimeout;

                _orConn.Open();

                oDA.Fill(retVal, "values");

                return retVal;

I get an exception when running that matches the title though. 

What am I doing wrong?
