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 8.13.2 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 8.7 Releasing Explicit memory blocks when the automatic release functionality is enabled.

If you are using the Explicit Memory Management functionality API, see 8.12 Implementing Java program that uses the Explicit Memory Management functionality API.

Hint

If memory usage of the Tenured area increases even if you tune the Java heap and the Explicit heap, and if a Java object causing a full garbage collection exists, check the option of placing the object in the Explicit heap.
