This section presents some basic memory administration concepts and explains the fundamentals about object allocation and garbage collection in the Oracle JRockit JVM. For information about how to use command line choices to tune the memory management system, see Tuning the Memory Administration System. Java objects reside in an space referred to as the heap. The heap is created when the JVM begins up and will increase or lower in size whereas the appliance runs. When the heap turns into full, garbage is collected.
