7.5 Objects that you can optionally place in the Explicit heap in the application

This section describes the objects that you can optionally place in the Explicit heap.

If you want to place Java objects other than the objects that are set in the J2EE server, in the Explicit heap, specify the objects that you want to place by using the automatic placement configuration file. For details on the automatic placement configuration file, see 7.13.2 Using the Explicit Memory Management functionality by using the automatic placement configuration file.

For details on the automatic release functionality of the Explicit Management Heap, see 7.7 Releasing Explicit memory blocks when the automatic release functionality is enabled.

If you are using the Explicit Memory Management functionality API, see 7.12 Implementing the Java program that uses the Explicit Memory Management functionality API.

Tip

Even after you have tuned the Java and Explicit heap sizes, if the memory used for the Tenured area increases and Java objects that can trigger Full GC exist, consider placing the objects in the Explicit heap.
