  • Abstract Java has become one of mainstream development programs, along with the expansion of the application level, providing a greater variety of API. However, due to the requirements and complexity of the applications, and the inexperienced developers, it will result in insufficient heap memory and cause the heap memory error. The occurrence of memory errors will cause the collapse of the entire JVM. It is difficult to trace the problems, especially in an environment for supporting a lot of multi-threads, such as WEB.
    The proposed H3M (Heap Memory Monitoring Mechanism) in this thesis, JVMTI, which is provided by Java, has been used as the basic of the main development. By applying the proposed mechanism, the components which occupy a lot of heap memory space can be determimed, so as to limit their memory accesses for preventing the error of insufficient memory. In addition, with the assistance of JMX, it helps to start the preventing mechanism by getting the usage of heap memory in a short period.
    This experimental result shows that the use of the proposed mechanism can effectively prevent heap memory errors, and facilitate the developers to get the information of the problems quickly.
