Microsoft ODBC for Oracle on Windows 2008 R2 x64

Question

I have server under Windows Server 2003 with Oracle 10 32bit. There are several ODBC data sources configured in ODBC Data Source Administrator.

Now I need to move all that system to Windows Server 2008 R2 x64. I've installed OS, Oracle server 12c x64, Oracle client 12 x64. Now I need to configure my ODBC data sources, but there is no Microsoft ODBC for Oracle driver.

Where can I find this driver to configure ODBC data source?

(I've tried 32bit tool from SystemWOW64, it has this driver but shows me exception "The Oracle(tm) client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle version 7.3 (or greater) clien costware installation." As far as I could say it looks for 32bit client, but there is no such)

Answer 1

对于64位，

“Microsoft ODBC for Oracle”不存在。 Microsoft仅提供32位版本。

您必须从Oracle下载并安装驱动程序：ODBC Developer Center或 64-bit Oracle Data Access Components (ODAC) Downloads

32位ODBC驱动程序（无论是来自Microsoft还是来自Oracle）都不能与64位Oracle客户端一起使用，架构必须匹配。
