一、常见需要分析dump文件场景 1.1 fullGC频繁 1.2 堆空间溢出 1.3 元空间溢出 二、准备工具 能分析dump文件的工具很多比如Java自带的jvisualvm、商业软件Jprofile、mat(MemoryAnalyzerTool)、IDEA等,除了mat和jvisualvm其他软件不能在Linux环境分析,当dump文件很大的时候不方便,mat-linux版本可以直接在服务器上生成报告...
3c. Once you’ve selected the .dmp file to analyze, click the “Upload Dump” button. The file size of a minidump .dmp file is normally quite small at around 150KB to 300KB so the upload won’t take very long. 3d. On the analysis report, take note of the MODULE_NAME and IMAGE_...

2、分析线程Dump的入手点 1、进入区等待:BLOCKED、waitting to lock、waitting for monitor entry,这些词表名代码层面已经存在冲突。 2、持续进行的IO:一般来说被捕捉到的runnable的IO调用都是有问题的,如runnable中有JDBC链接的代码 3、非线程调度的等待区等待:in Object.wait()(情况1可能会导致这个情况,造成大量...
MAT(Memory Analyzer Tool)工具是eclipse的一个插件,使用起来非常方便,尤其是在分析大内存的dump文件时,可以非常直观的看到各个对象在堆空间中所占用的内存大小、类实例数量、对象引用关系、利用OQL对象查询,以及可以很方便的找出对象GC Roots的相关信息,当然最吸引人的还是能够快速为开发人员生成内存泄露报表,方便定位问题...
My friend John acquired a memory dump from Windows 10, but he could analyze this memory dump with any tools in hand. He was frustrated and thought maybe he should use another acquiring tool. Actually it's not acquiring tool's fault. All he need is a tool support analying windows 10 mem...
Process Dump is a Windows reverse-engineering command-line tool to dump malware memory components back to disk for analysis. Often malware files are packed and obfuscated before they are executed in order to avoid AV scanners, however when these files are executed they will often unpack or inject...
