I don't get it ...
I called my program with the following main & now I can have it up & running
on two VM's simultaneously ...

<snip>
  public static void main (String[] args)
    throws SQLException
  {
    BasicConfigurator.resetConfiguration ();
    BasicConfigurator.configure ();

    InsertRandomData[] ird = new InsertRandomData[NBR_THREAD];
    Thread[] t = new Thread[NBR_THREAD];
    int i = 0;
    for (; i<ird.length; i++)
    {
      ird[i] = new InsertRandomData(NBR_OF_RECORDS);
      t[i] = new Thread (ird[i]);
    }

    for (i = 0; i<ird.length; i++)
      t[i].start();
  }
</snip>
