∟Running JRockit Mission Control

This section provides a tutorial example on how to run JRockit Mission Control 4.1 installed as part of JRockit R28.2.7.

Here is what I did to try JRockit Mission Control on my Windows 7 system:

1. Run my LongWhile.java program with JRockit JVM R28.2.7 in the command window:

>type LongWhile.java
/* LongWhile.java
 * Copyright (c) HerongYang.com. All Rights Reserved.
 */
class LongWhile {
   public static void main(String[] a) {
      Runtime rt = Runtime.getRuntime();
      System.out.println(" Free memory: " + rt.freeMemory());
      System.out.println("Total memory: " + rt.totalMemory());
      while (true);
   }
}

>\Progra~1\java\jrockit-jdk1.6.0_45-R28.2.7-4.1.0\bin\javac \
   LongWhile.java

>\Progra~1\java\jrockit-jdk1.6.0_45-R28.2.7-4.1.0\bin\java LongWhile

 Free memory: 63434800
Total memory: 67108864

2. Launch JRockit Mission Control in another command window:

>\Progra~1\java\jrockit-jdk1.6.0_45-R28.2.7-4.1.0\bin\jrmc

3. Click "Window" > "Show View" > "JVM Browser" menu, you will see the "JVM Browser" panel displayed.

4. Open the "Local" folder under "Discovered", you will see two entries "[1.6] LongWhile (6,804)" and "This Mission Control" representing 2 JVM instances that are running on my local machine.

5. Right mouse click on "[1.6] LongWhile (6,804)" and select "Start Console", you will see the overview dashboard displaying general information on my "LongWhile" JVM instance. See the screenshot below:
