Update Notification doesn't work on Oracle11g

Question

Hi
I'm using ODP.NET 11.1.0.6.0 which is accompanied with Oracle11gR1.
When I use OracleDependency to get update notification,
There are 2 problems:
1. I can't receive update notification, when I change data.
2.Port property of OracleDependency doesn't affect listening port.
I checked by netstat.
Are there any problem in the following code.
.NET Client is:
Windows XP SP2
Oracle 11gR1
DB Server is:
Windows XP SP2
Oracle 11gR1
Both are on Vistual Machine(VMWare Server)
and Japanese environment.
I add CHANGE NOTIFICATION rights to user,
And db's dbchange_notification_enable hidden parameter is true.
CreateTable.sql
CREATE TABLE UN_TEST (
     ID NUMBER(10,0) NOT NULL,
     TEXT1 NVARCHAR2(20) NOT NULL,
     TEXT2 NVARCHAR2(250) NULL
,CONSTRAINT PK_CUSTOMERS PRIMARY KEY (ID)
console program is

static void Main(string[] args)
// Port setting doesn't affect all.
// this settings ignored and listens random port.
OracleDependency.Port = 10005;
TestNotify();
Console.ReadLine();
public static void TestNotify()
// DELETE and init data
ExecuteCommand("DELETE FROM UN_TEST");
ExecuteCommand("INSERT INTO UN_TEST (ID,TEXT1) VALUES(1, 'N1')");
OracleConnection conn = new OracleConnection();
OracleDependency oraDep = null;
conn.ConnectionString = ConnectionString;
conn.Open();
try
using (OracleCommand oraCmd = conn.CreateCommand())
oraCmd.CommandText = "SELECT ID,TEXT1,TEXT2 FROM UN_TEST";
oraDep = new OracleDependency(oraCmd, true, 60 * 1000, false);
oraDep.OnChange += new OnChangeEventHandler(oraDep_OnChange1);
using (OracleDataReader reader = oraCmd.ExecuteReader())
while (reader.Read())
Console.WriteLine(reader["ID"] + ":" + reader["TEXT1"]);
finally

Changed = false;
// UPDATE

// wait 120 seconds
for (int i = 0; i < 120; i++)

String s = String.Format(sql, args);
oraCmd.CommandText = s;

Console.WriteLine(DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss.fff") + " " + ret + " rows updated : " + s);
oraTx.Commit();
finally
conn.Close();
return ret;
}

Nobody had this trouble...?
I even tried DFU mode - to no luck! Gutted about this, because otherwise its perfect... but I am beginning to suspect something is really wrong with it now.
Well, there is good news - I called Apple, spoke to a fantastic chap called DJ and he's sorting out a replacement for me. I can't afford to be without my iPhone, so paid the fee to get a replacement sent out first. I guess these things happen, and better to sort it out in warranty, than out of.
But seriously, nobody experienced this at all??
