【达梦数据库】Windows达梦管理工具打开失败：An error has occurred_ See the log file_达梦数据库管理工具打不开_AlphaGuaGua的博客-程序员宅基地

今天安装好达梦数据库之后，发现DM管理工具打开报错，如下截图

找到上面所说的目录的日志文件，打开后是如下内容：

看了哈日志，大概是“无法写入平台元数据区域”，具体啥原因也不知道。

查了下原因，网上说说是电脑之前因某些操作把 “My Documents” 文件夹改到了D盘下，而安装程序会假设它位于C盘并且尝试在那里打开工作区。这个不晓得对不对，反正我电脑没有改过，但还是报错。

解决思路：给启动程序加入 “-data”属性，指定合理的工作区路径；

直接修改DM管理工具启动程序对应的ini配置文件即可，如DM管理工具对应的“manager.exe”，需修改“manager.ini”。这个文件在安装目录下的tool目录。

原文件如下：

-startup
plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.2.R36x_v20101222
-product
com.dameng.manager.product
-showSplash
manager.bmp
-data
workspace/manager
-vm
../jdk/bin
-vmargs
-DDM_HOME=../
-Djava.library.path=../bin
-Ddameng.log.file=log4j.xml
-Ddameng.isql.explorer.root=workspace/local/isql
-Ddameng.dts.explorer.root=workspace/local/dts
-Duse_bak2=true
-Dgrant_vti_role=false
-Dapp.name=manager.exe
-Dosgi.nl=zh_CN
-Xms256m
-Xmx2048m

注意看-data字段，原来的文件里面是workspace/manager，这里是一个相对路径，DM管理工具打开时无法识别路径，造成打开失败。

所以，直接更改为一个绝对路径即可。更改后的内容为（示例）：

-startup
plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.2.R36x_v20101222
-product
com.dameng.manager.product
-showSplash
manager.bmp
-data
C:/Users/Lucky_W/.eclipse/workspace/manager
-vm
../jdk/bin
-vmargs
-DDM_HOME=../
-Djava.library.path=../bin
-Ddameng.log.file=log4j.xml
-Ddameng.isql.explorer.root=workspace/local/isql
-Ddameng.dts.explorer.root=workspace/local/dts
-Duse_bak2=true
-Dgrant_vti_role=false
-Dapp.name=manager.exe
-Dosgi.nl=zh_CN
-Xms256m
-Xmx2048m

保存即可。

如果更改后无法保存，是因为DM程序把文件夹权限重设了，文件修改完无法保存，直接在其他路径修改后覆盖即可。

修改保存后，在打开达梦管理工具，就能正常打开啦！
