推荐答案

使用11.2 Release 3 (11.2.0.2.1) with Xcopy Deployment"版本的Oracle Data Access Component安装过程好像坏了.要解决此问题，您必须在 GAC 中注册缺少的程序集.要为这个特定版本执行此操作，请从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:WindowsassemblyGAC_32Oracle.DataAccess4.112.2.0__89b483f429c47342

copy %ORACLE_HOME%odp.netin4Oracle.DataAccess.dll C:WindowsassemblyGAC_32Oracle.DataAccess4.112.2.0__89b483f429c47342

md C:WindowsassemblyGAC_32Oracle.Web4.112.2.0__89b483f429c47342

copy %ORACLE_HOME%asp.netin4oracle.web.dll C:WindowsassemblyGAC_32Oracle.Web4.112.2.0__89b483f429c47342

请注意，这仅注册 DLL 的而不是其他语言资源.因此，如果您使用除英语以外的任何其他语言(de、es、fr、it、ja、ko、pt-BR、zh-CHS 和 zh-CHT)，那么您还需要使用相应的资源注册这些语言文件.

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.

如果您在机器上安装了 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.netin4Oracle.DataAccess.dll
gacutil /i %ORACLE_HOME%asp.netin4oracle.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.

附:或者你可以试试 这个.

P.S. Or you can try this.
