Need help making this class Runnable.

Question

Hello,
This class (see below) is working fine the way it is but I have a little problem, I need to execute aprox 500+ commands and each command takes between 30sec to 3 minutes to complete which translate into hours for the job to finish.
I want to speed the process by multi-tasking and executing (possibly) all commands simultaniously by somehow making this class Threaded/Runnable (miltitasking). There must be something tricky about Runtime class and cannot figured it out.
Your help would be highly appreciated.
Regards,
Ulises
public class CmdTest {     
public static void main(String[] args) throws java.io.IOException {
String outFile = "./ds8300/lsvogrp.txt";
PrintWriter bout = null;
try {
bout     = new PrintWriter(                         new FileWriter(new File(outFile)));     
} catch (IOException e) {
     e.printStackTrace();
Runtime run = Runtime.getRuntime();
run.traceMethodCalls(true);
Process proc2 = run.exec("cmd /c dscli -user user -passwd psw" + "lsvolgrp -l");
BufferedWriter ot = new BufferedWriter(
new OutputStreamWriter(proc2.getOutputStream()));
BufferedReader br = new BufferedReader(
new InputStreamReader(proc2.getInputStream()));
BufferedReader er = new BufferedReader(
new InputStreamReader(proc2.getErrorStream()));
try {
String s;
while((s=br.readLine())!=null) {
     System.out.println(""+s);
     bout.println(s);
while((s=er.readLine())!=null) System.out.println("ERR:"+s);
bout.close();
System.exit(0);
}catch (Exception ie) { //catch (InterruptedException ie) {
System.out.println("Interrupted:"+ie.getMessage());}
}

Seems like the same question you asked last year.

The proper way to design software is to start at the beginning and design Classes. Not try to butcher that which is working.
You're running work outside the JVM and this work might interfere with other, similar work (the multi-threading issue.)
I'd start with paper and pencil and see what conflicts might arise.
