Oracle to netezza

Question

Oracle db ver 10.2.0.3
via a simple java program I am tring via jdbc to connect to a netezza server. the code work from the command line but does not work within the Oracle JVM. I did try the grants to allow access to the applications a couple of ways but no luck. via load java the nz jdbc driver and this code was loaded into the Oracle db.
package nzTest;
import java.sql.*;
public class main
Connection conn;
public static void main(String[] args){ new main();}
public static void doConnNZ () {new main();}
public main()
  try
   Class.forName("org.netezza.Driver").newInstance();
   System.out.println("h1");
   String url = "jdbc:netezza://the_host:5480/the_db";
   System.out.println("h2");
   conn = DriverManager.getConnection(url, "user", "pwd");
   System.out.println("h3");
   conn.close();
   System.out.println("connected and closed");
  catch (Exception e) {e.printStackTrace();}
}the error message I get is
h1
h2
org.netezza.util.PSQLException: The connection attempt failed because Exception: java.net.SocketException: Socket option not supported by PlainDatagramSocketImp

        at nzTest.main.doConnNZ(main.java:11)My questions are: what would the java_dbms package call be to allow access to anywhere from user NZ within the oracle db?
The error message kind of seems like it is saying the NZ driver is doing something PlainDatagramSocketImp does not do. Is this what it is getting at. Is there any way to tell? and any ideas to make this work would be helpfull.
thanks

This seems like a bug in this version. I can see that the option TCP_DELAY , a valid one, not being set. The best way would be for you to open a bug. I could do so . What needs to happen is for you to get a patch with this bug fix. This is already fixed in 11g.
