提问by Alex
I keep getting and seeing this message
我不断收到并看到此消息
Failed to write core dump. Minidumps are not enabled by default on client versions of Windows
无法写入核心转储。默认情况下，客户端版本的 Windows 上不启用小型转储
So I need to know
所以我需要知道
- How to enable minidumps in Java (on a Windows machine)
- (optional) How interpret a minidump once I have it
- 如何在 Java 中启用小型转储（在 Windows 机器上）
- （可选）一旦我拥有它，如何解释小型转储
I tried to find an answer for those 2 questions but what I found are very specific answers for niche questions and that did not satisfied me.
我试图找到这两个问题的答案，但我发现的是针对小众问题的非常具体的答案，这并没有让我满意。

You will need the following JVM option:
您将需要以下 JVM 选项：
-XX:+CreateMinidumpOnCrash
Then the minidump will be as large as the memory used by your JVM.
然后小型转储将与您的 JVM 使用的内存一样大。
To interpret the minidump you can install the free Visual Studio C++ Express edition for your platform: http://www.visualstudio.com/en-us/products/visual-studio-express-vs.aspx
You will also need the symbols for the DLLs that you are interested in. There is some information on using the Microsoft Symbol server here: http://support.microsoft.com/kb/311503
You would also need the symbol files for the JVM.
要解释小型转储，您可以为您的平台安装免费的 Visual Studio C++ Express 版本：http: //www.visualstudio.com/en-us/products/visual-studio-express-vs.aspx
您还需要您感兴趣的 DLL 的符号。这里有一些关于使用 Microsoft 符号服务器的信息：http: //support.microsoft.com/kb/311503
您还需要 JVM 的符号文件。
