dump文件记录了jvm运行期间内存状态,线程执行执行情况,常用的有thread dump,heap dump。简单来说,thread dump是记录线程执行信息,heap dump是记录jvm内存信息。 thread dump : 主要记录JVM在某一时刻各个线程执行的情况,以栈的形式显示,是一个文本文件。通过对thread dump文件可以分析出程序的问题出现在什么地方,从而定...
Heap dump helps us to identify the primary causes for the error and other details, for instance, the number of objects in every class, memory usage for every class, etc. It also assists in capturing the memory size occupied by each Java object of an application. All this captured informati...
Review the http://aem-host:port/system/console/memoryusage screen If the “Old Generation” (JDK 7 and earlier) or “Tenured Generation” (JDK8 or later) usage is high then this could be a sign of a heap memory utilization issue. Click “Run Garbage Collector” to request the JVM to ...
Use the following commands to record and analyze the heap memory allocations in a running process. This analysis focuses on stack traces.
Dump & Java Heap in a single snapshot allowing you to determine (or to rule out) any pressure point in a particular Java Heap memory space along with current Thread computing currently being done at that time. As you can see in our sample Thread Dump, the Java Heap OldGen is maxed ...

So you enabled verbose GC logs and obtained the logs. Congratulations. You have done one of the most important steps in troubleshooting JVM memory issues. But merely having the log does not do any good. You need to analyze and determine if there is a smoking gun. Here is how to do i...

If we know the memory usage of our application well, it can be advantageous to specify a fixed size both for the total heap and the young generation, and it can also be useful to specify a ratio. If we only know a little or maybe nothing at all about our application in this respect...
