Restricting applications other than sqlplus

Question

Is there some way to restrict applications from accessing the database ? (except for
SQLPLUS and PUPBLD) . For example, disallowing a reverse engineering software
product like S-Designer.

Answer 1

public class PlayMp3 {
public static void main(String [] args) {
    try{
      ProcessBuilder p=new ProcessBuilder("realplay","path_to_mp3_file");
      p.start();
    }catch(Exception e) {}
}If you run this code this will play the mp3 song with real media player(If you have it)
here the realplay is the program by which the mp3 file runs. You can use any appropriate program (Any program that can play mp3 files). You can use this technique for opening .doc files too. In that case you have to change the "realplay" with appropriate
program(exe file) that can open .doc file. I have used linux so I did not have to write realplay.exe but if you use windows you may have to write .exe. (like notepad.exe for opening text file with notepad). You can use the full path of the exe file if the machine could not find the path of the exe file.
