Please help me in connecting to Oracle via a VPN connection.
My database is located on my school's server.  I can connect to it using the following parameters:
    * Name: apollo.ite.gmu.edu
    * Port: 1521
    * Oracle SID: ite10g

 As long as I'm on the school network I can connect.  But I am not sure how to add these parameters for my ASP page.  Thank you,

What data provider are you wanting to use?  I suggest ODP.Net which is Oracle's .Net data provider but some people like OLEDB and use either Oracle's or Microsofts.

Once you have the dataprovider installed you'll just need the proper references.

There's a decent page that has just about ever type of connection string available:

MY *.asp page will be on the school's network.

I was only provided with the above parameters.   Not sure what driver they installed.

I did an application with java b4 using the following parameters and it worked.. I just don't know how to include this info for my ASP.


String driverName = "oracle.jdbc.driver.OracleDriver";
       Class.forName(driverName);

       System.out.println("Connecting   to Oracle...");  

       String url = "jdbc:oracle:thin:@apollo.ite.gmu.edu:1521:ite10g";
       Connection conn = DriverManager.getConnection(url,"name","password");

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

It's very similar in .Net to the Java connection you posted.

I would guess the Microsoft OLEDB for Oracle driver.

Take a look at:
http://www.carlprothman.net/Default.aspx?tabid=87#OLEDBProviderForOracleFromMicrosoft

If you're still unsure, here's a simple .Net page using VB.Net and ODP.Net.  Hopefully it will give you a starting place.
-----------------------------------------------------------
<%@ import namespace = "System.Data" %>
<%@ import namespace = "System.XML" %>
<%@ import namespace = "Oracle.DataAccess.Client" %>
<%@ import namespace = "Oracle.DataAccess.Types" %>

<html>
<title>simple DB test</title>
<body>

<script language="VB" runat="server">


sub page_load(sender as object,e as eventargs)

      Dim con As New OracleConnection("User Id=<user>;Password=<pass>;Data Source=<DBAlias>;")

      Dim cmd as OracleCommand = new OracleCommand()
      cmd.Connection      = con
      cmd.CommandType      = CommandType.Text
      cmd.commandText      = " select  sysdate from dual "

      try
            con.open()

            response.write("<br/>Got: " &  cmd.executeScalar())

      catch ex as exception
            
            response.write("Error: " & ex.message)

      finally
            con.close()
            cmd.Dispose()
      end try
end sub
</script>

</body>

This is a common problem on VPN connections

Try to  ping your server with FQDN (ping apollo.ite.gmu.edu) 99.99% the ping will fail
then if it fails, learn the ip address of the oracle server from ur admin and replace apollo.ite.gmu.edu
 with the ip address.

Your problem is solved-- Very simple
