This section describes the settings in the execution environment for using the Explicit Memory Management functionality.

Note

On the J2EE server, objects related to an HTTP session and objects for communication with the redirector are set to be placed in the Explicit heap area by default.

Before starting the operations, estimate the required Explicit heap memory size and tune JavaVM option (-XX:HitachiExplicitHeapMaxSize option) to an appropriate value. For details on the tuning of the Explicit heap, see 7.2.2 Tuning procedure in the uCosminexus Application Server System Design Guide.
