Unhandled Exception: System.Net.Sockets.SocketException: Protocol option not supported

[marcusperez]

Hi,

I can't figure out what the problem is here. Hope someone can help me out. Thanks in advance!

Here are some details that might help...

• Windows 7 (Host machine)
  Solaris 10 (Virtual machine - Virtualbox)
  Mono
  C# compiled through Xamarin Studio
  Oracle 11g R2

I am executing the console application on the virtual Solaris Machine through Mono within the Gnome terminal. The Oracle database server is on the host machine (Windows 7).

I am able to connect from the guest Solaris machine to the Oracle database on the host machine using Sql Developer so I know I can reach the server.

Here's the C# code:

Code: Select all

using System;
using Devart.Data.Oracle;
using System.Net.Sockets;

namespace Console
{
	class MainClass
	{
		public static void Main (string[] args)
		{
			System.Console.WriteLine ("Hello World!");

			OracleConnectionStringBuilder connectionSB = new OracleConnectionStringBuilder();

			connectionSB.Direct = true;
			connectionSB.Server = "172.16.0.4";
			connectionSB.Port = 1521;
			connectionSB.Sid = "Oracle11g";
			connectionSB.ConnectMode = OracleConnectMode.SysDba;
			connectionSB.UserId = "sys";
			connectionSB.Password = "password";
			OracleConnection dbcon = new OracleConnection (connectionSB.ConnectionString);
			dbcon.Open ();
			dbcon.Close ();
			dbcon = null;
		}
	}
}

Here's the exception:

What am I missing?

Mono for Solaris does not support SO_SNDTIMEO and SO_RCVTIMEO socket options. dotConnect for Oracle uses the ReceiveTimeout or SendTimeout properties for the socket object when a connection is opened. When working with the SendTimeout and SendTimeout properties, the SO_SNDTIMEO and SO_RCVTIMEO socket options are used. Thus, dotConnect for Oracle can't be used on Solaris system.
