This section provides a tutorial example on how to use Oracle JRockit Management Console to monitor and manage HotSpot JVM instances.

JRockit Management Console can also be used to monitor and manage HotSpot JVM as shown in the tutorial:

1. Compile and run LongWhile.java with HotSpot 1.6.0 in a command window:

>\Progra~1\java\jdk1.6.0_45\bin\javac LongWhile.java

>\Progra~1\java\jdk1.6.0_45\bin\java LongWhile

 Free memory: 16055544
Total memory: 16252928

2. Compile and run LongSleep2.java with JRockit R28.2.7 in another command window:

>\Progra~1\java\jrockit-jdk1.6.0_45-R28.2.7-4.1.0\bin\javac \
   LongSleep2.java
