在
Windows
环境下(XP
和 Win 7
):
- 当进程在系统上崩溃时,最好的自动生成崩溃转储的方法是什么?
- 一个安装程序 (MSI) 包可以做到这一点吗?
Windows
环境下(XP
和 Win 7
):
在Windows上自动转储任何/特定进程的最佳方法之一是配置注册表中一组条目。我在64位Windows 7上尝试了以下内容。
打开notepad.exe,粘贴以下内容并将其保存为“EnableDump.reg”。您可以随意命名。
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps]
"DumpFolder"=hex(2):44,00,3a,00,5c,00,64,00,75,00,6d,00,70,00,00,00
"DumpCount"=dword:00000010
"DumpType"=dword:00000002
"CustomDumpFlags"=dword:00000000
双击 "EnableDump.reg" 并选择 '是'。 我已经将转储文件夹设置为 'd:\dump'。 您可以将其更改为任何您想要的文件夹。
尝试执行一个崩溃的应用程序,Windows 将显示错误对话框。 选择 '关闭程序' 选项。 之后,您将在配置的文件夹中看到转储文件。 转储文件的名称将是.exe..dmp。
有关详细信息,您可以参考下面的链接。

DumpType
设置为0(自定义dump)时,似乎只使用CustomDumpFlags
。如果使用DumpType
2(完整dump),则不需要设置CustomDumpFlags

Windows XP: 以下步骤可启用自动崩溃转储:
1) Open a command prompt, running as administrator
2) Run drwtsn32 -i. This will install Doctor Watson as the default debugger when something crashes
3) Click Ok
4) From the command prompt, run drwtsn32
5) Set the Crash Dump path to your favorite directory, or leave the default.
6) Set the Crash Dump Type to mini. Note that under some circumstances, we may ask you for a full crash dump.
7) Make sure the Dump All Thread Contexts and Create Crash Dump File options are selected.
8) Click Ok
9) If a user.dmp file already exists in the Crash Dump path, delete it.
