One of the questions was how to programmatically dump the heap from applications. For example, you may want to dump multiple heap snapshots from your application at various points in time and analyze those off line using jhat. Yes, you can dump heap from your application -- but you have to...

# JavaDumping导出和分析 在Java开发中,有时会遇到应用程序崩溃或性能问题,这时我们需要分析Java虚拟机(JVM)的状态。为了更好地调查这些问题,Java提供了一种称为“dumping”的机制,通过它可以导出JVM在特定时间点的内存快照和线程状态。本文将简要介绍Javadumping的概念、导出方法以及如何分析这些数据,并提供相关代码示例...

You can also use the Modify command to generate a Java core dump whenever a timeout occurs. Note: The dumpThreads command creates other types of dump files depending on the -Xdumps settings. Dump output varies depending on the platform and might include system core files, heap, and snap du...
So in this case we have 3 active sessions, or at least 3 sessions that are still on the heap, the session timeout is set to 20 minutes and the first session holds an amazing ~268 MB (actually more like 256,001 MB, but what's a few MB in the sceme of things). Part #2 (Dum...
concept. It is a trace-based JIT, compiling only hot code traces rather than method-at-a-time strategy typically found on server-class JITs. It attempts to minimize heap usage, and it requires no persistent storage. The goal is to give a quick performance boost using very little heap and...
