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...
Programmatically dumping heap from Java applications In the troubleshooting BOF, we demonstrated how to use thejmap -dumpoption to dump heap dump of a running application and showed how to browse/analyze the resulting binary heap dump using thejhattool. One of the questions was how to programmatic...
A Java core dump includes all of the memory that is being used by the JVM, and includes the state of every thread in the server processes. If you want to disable the generation of the heap dump, set the wsadmin_dumpthreads_enable_heapdump environment variable to0. If you want to disabl...
I know of !gcroot but it's slow and not really practical to run it on every object. Ideally there would be a !collect command that would force or simulate a GC on the current heap. But perhaps I am thinking of this in entirely the wrong terms... Well that's it, if you feel ...

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...
# 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...
