7.11.2 Estimation concept

The memory size of the Explicit heap used in an application is estimated before you operate an application. Actually the memory size is estimated by checking an event log of the explicit management heap functionality after the application is operated. For details about how to estimate, see 7.11.3 Memory size used in the application.

When investigating the usage of the Explicit heap after the application is operated or is being developed, use the JavaVM log file and Java APIs. For details about the procedures for investigating after application development or operations, see 7.13 Errors that occur during the application of the Explicit Memory Management functionality and the solutions.

Reference note
The information that you can use for estimating memory size is also output to the statistical information. For details about the tuning of memory size using statistical information, see 7.10.5 How to estimate using statistical information.
This section also describes the correspondence between items output to statistical information and items output to thread dump.
