推荐答案

使用带有Xcopy部署的11.2发行版3(11.2.0.2.1)"版本的Oracle数据访问组件安装过程似乎已损坏.要解决此问题，您必须在GAC中注册缺少的程序集.为此，请在管理员控制台中运行以下命令:

It seems the Oracle Data Access Component installation process using the "11.2 Release 3 (11.2.0.2.1) with Xcopy Deployment" version is broken. To fix this you must register the missing assemblies in the GAC. To do this for this specific version run these commands from within an administrator console:

md C:\Windows\assembly\GAC_32\Oracle.DataAccess\4.112.2.0__89b483f429c47342\ copy %ORACLE_HOME%\odp\bin\4\Oracle.DataAccess.dll C:\Windows\assembly\GAC_32\Oracle.DataAccess\4.112.2.0__89b483f429c47342\ md C:\Windows\assembly\GAC_32\Oracle.Web\4.112.2.0__89b483f429c47342\ copy %ORACLE_HOME%\asp\bin\4\oracle.web.dll C:\Windows\assembly\GAC_32\Oracle.Web\4.112.2.0__89b483f429c47342\

请注意，这仅注册DLL的资源，而不注册其他语言的资源.因此，如果您使用的是英语以外的其他语言(de，es，fr，it，ja，ko，pt-BR，zh-CHS和zh-CHT)，则还需要使用相应的资源进行注册.文件.

Note that this registers only the DLL's but not other languages resources. So, if you are using any another language than English (de, es, fr, it, ja, ko, pt-BR, zh-CHS, and zh-CHT), then you need to register these as well using the corresponding resource file.

如果在计算机上安装了Visual Studio，则可以发出以下命令:

If you have Visual Studio installed on the machine, you can issue the following commands instead:

gacutil /i %ORACLE_HOME%\odp\bin\4\Oracle.DataAccess.dll gacutil /i %ORACLE_HOME%\asp\bin\4\oracle.web.dll

注意:在Visual Studio安装文件夹下查找gacutil.exe.

Note: look for gacutil.exe under the Visual Studio installation folder for it.

希望这会有所帮助.
