The number of flags that someone can change on the Sun Java Virtual Machine (JVM) is astounding. Most of them are garbage collection (GC)-related and have many dependencies, not only on the system you are using but also to each other. Tuning GC flags seems like it should be difficult and In addition, Java SE library classes and methods may be stored here. Classes may get collected (unloaded) if the JVM finds they are no longer needed and space may be needed for other classes.Garbage Collection. Performance Tuning. Interfaces.

The Java Virtual Machine is an abstract computing machine. Like a real computing machine, it has an instruction set and manipulates various memory areas at run time.Today we will look into different parts of JVM memory and how to monitor and perform garbage collection tuning. In the G1 Garbage collector there is no separation between younger and older regions. Rather the heap memory is organized into smaller parts called Regions.As G1 is still under development, the goal is to make G1 perform better than CMS and eventually replace it in a future version of Java SE Find a more detailed description of the CMS in the article Java SE 6 HotSpot Virtual Machine Garbage Collection Tuning. The Java Virtual Machine Specification defines the JVM as: An imaginary machine that is implemented by emulating it in software on a real machine.Garbage Collection.
