    private string GetDbmsOutputLine()
    {
        OracleCommand command = new OracleCommand
        {
            Connection = <connection>,
            CommandText = "begin dbms_output.get_line(:line, :status); end;",
            CommandType = CommandType.Text
        };

        OracleParameter lineParameter = new OracleParameter("line",  
            OracleType.VarChar);
        lineParameter.Size = 32000;
        lineParameter.Direction = ParameterDirection.Output;
        command.Parameters.Add(lineParameter);

        OracleParameter statusParameter = new OracleParameter("status",  
            OracleType.Int32);
        statusParameter.Direction = ParameterDirection.Output;
        command.Parameters.Add(statusParameter);

        command.ExecuteNonQuery();

        if (command.Parameters["line"].Value is DBNull)
            return null;

        string line = command.Parameters["line"].Value as string;
