如何运行独立的Eclipse MAT? [英] How do I run stand-alone Eclipse MAT?

问题描述

我使用jmap生成了hprof.

I generated hprof using jmap.

sudo ~/jdk/bin/jmap -F -dump:file=app.hprof 5003  

现在，我在Eclipse中解析* .hprof时遇到OOM/'Java Heap Space'错误.我想我需要独立运行它.

Now, I am getting OOM / 'Java Heap Space' error while parsing *.hprof in eclipse. I think I need to run it as stand-alone.

我如何运行它?有参考吗?

How do I run it? any references?

推荐答案

我假设您已经下载了采用独立Eclipse RCP应用程序形式的Eclipse MAT .如果不是，请立即执行操作，然后将存档解压缩到适合您的文件夹中.

I assume, you've downloaded Eclipse MAT in the form of Standalone Eclipse RCP Application. If not - do so now, and extract the archive to a folder that suits you.

您将获得OOME，因为MAT的可用内存太少(您正在解析的堆转储太大).

You're getting the OOME, because MAT has too few memory available (the heap-dump you're parsing is too big).

要使堆变大，请编辑您的MemoryAnalyzer.ini文件(该文件应位于MAT目录中)，然后向其中添加以下行:

To make the heap bigger, edit your MemoryAnalyzer.ini file (it should be in your MAT directory), and add the following lines to it:

-vmargs
-Xmx2048M

2048M表示JVM将有2 GB的堆空间可用.也许1 GB就足够了.

The 2048M means 2 gigabytes of heap space will be available to the JVM. Perhaps 1 gigabyte will be enough for you.

注意！ 如果您将MAT用作Eclipse插件，则可以通过在Eclipse目录中编辑eclipse.ini来完成相同的操作.

Note! If you are using MAT as an Eclipse plugin, you can probably do the same trick by editing eclipse.ini in your Eclipse directory.
