A heap dump does not contain allocation information so it cannot resolve questions like who had created the objects and where they have been created. heap dump中不含分配信息,所以不提示对象在哪里分配,被谁分配。 Shallow heap &Retained heap Shallow heapis the memory consumed by one object. An ob...
Once called, the system will look for any occasions where it sees the associated process with a larger pss size and, when this happens, automatically pull a heap dump from it and allow the user to share the data. Note that this request continues running even if the process is killed and...

HeapDumpTestWithActiveProcess.java is the only test we have that tries doing stack walking with an application that is still in the process of starting up. Because of this it detects a lot of bugs in SA bug due to threads being in bad states.JDK-8244383is one such example, causing failu...
JavaCore是关于CPU的,而HeapDump文件是关于内存的。 JavaCore文件主要保存的是Java应用各线程在某一时刻的运行的位置,即JVM执行到哪一个类、哪一个方法、哪一个行上。它是一个文本文件,打开后可以看到每一个线程的执行栈,以stack trace的显示。通过对JavaCore文件的分析可以得到应用是否“卡”在某一点上,即在某...
