SSMA无法找到指定的提供者

标签： oracle odac sql-server-migration-assi

我已经安装了完整的oracle客户端12.2.0，并且我尝试使用SSMA将一些数据库从oracle迁移到sql服务器，但是当我尝试连接到oracle时，出现以下错误：

Unable to find specified provider.
Compatible Oracle Data Access Connectivity libraries were not found on the machine.

我已经设置了环境变量HOME_ORACLE，并且在安装过程中默认设置了PATH，所以我排除了问题所在。 我还搜索了有关ODAC的信息，所有提示都使我想起了oracle istant提供程序，但是由于我使用管理员安装（完整）安装了客户端，因此我认为该安装也将涵盖它们。 有什么建议吗？

编辑：我尝试使用标准模式和tnsnames模式登录，但结果相同

看起来Oracle Universal Installer 12.2中有一个错误，它没有注册ODP.NET组件。您可以在下面运行脚本（根据系统修改文件夹名称）以正确配置它们。

set Oracle_x64=c:\oracle\product\12.1\Client_x64\odp.net
set OraProvCfg_x64=%Oracle_x64%\bin\4\OraProvCfg.exe

set Oracle_x86=c:\oracle\product\12.1\Client_x86\odp.net
set OraProvCfg_x86=%Oracle_x86%\bin\4\OraProvCfg.exe

set TNS_ADMIN=C:\oracle\network\admin

更新

根据Oracle Doc ID 2272241.1，这似乎是出于故意：

  

适用于：
  适用于.NET的Oracle数据提供程序-版本12.1.0.2及更高版本
  Microsoft Windows x64（64位）
  Microsoft Windows（32位）

     

症状
  在安装12.2 Oracle Data Provider for .Net时，该提供程序   不会自动在全局程序集缓存（GAC）中注册。

     

更改
  移至Oracle Provider for .Net的12.2版

     

原因
  这是预期的行为。由于使用了许多环境   从12.2开始，ODP.Net的多个版本并排   安装程序不会在以下位置自动注册ODP.Net提供程序：   默认情况下为GAC。

     

解决方案
  如Doc ID中所述将dll手动注册到GAC中   1169890.1：HOWTO：使用OraProvCfg.exe从全局程序集缓存中添加/删除Oracle程序集的示例使用

但是，我认为这是一个错误。并行运行ODP.Net的多个版本是非常困难的，因为Oracle.DataAccess.dll的版本必须完全匹配Oracle Client的版本。安装多个Oracle客户端（即，对于64位和32位，每个客户端都安装多个）通常会导致很多问题，而且很少见。
