7.7.3 How to save in the Explicit heap
This subsection describes how to save and manage the objects that exists for a fixed time period, in the Explicit heap by changing Java programs and not by performing tuning. The Explicit heap is an area that is not subject to GC. By using the Explicit heap, you can prevent objects from moving to the Tenured area and make Full GC occur less often. You can also use automatic allocation setup file to allocate the object directly in Explicit heap. For details, see 7.11 Explicit heap tuning. On Application Server, the objects related to HTTP session are managed by Explicit heap.
