sql server 2008 r2 64位 如何连接oracle

 

一：环境

操作系统环境：Windos Server
2008 R2 64位

       所需软件版本：SQLSERVER 2008 R2 64位

                                   Oracle 11g client 32位和Oracle
11g client 64位

二：问题

        用Oracle的客户端去连接远程Oracle数据库可以，但用SQL SERVER去连接时，总是报一个OraOLEDB.Oracle.1没有提供的错误。

三：解决方法

        0、先去Oracle官网上下载32位和64位的客户端。地址如下：

        http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html    

        1、安装32位的Oracle客户端，存放路径C:\Oracle\product\11.2.0\client_32

   2、安装64位的Oracle客户端，存放路径C:\Oracle\product\11.2.0\client_64

这时会报一个内存不足的警告，忽略掉。

   3、找到注册表项HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\MTxOCI

OracleOciLib值改为oci.dll、

OracleSqlLib值改为orasql11.dll、

OracleXaLib值改为oraclient11.dll。

       4、HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSDTC\MTxOCI对它做同样的修改

四、原文

  Download 32 and 64-bit clients fromhttp://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html(click "see all" to see
different versions, otherwise, you'll be downloading the complete Oracle program. Your downloads should be about 600 meg each)
Run 32-Bit install on the SQL Server. Select "Custom"
For Oracle Base, enter "C:\Oracle"
For "Software Location", change to C:\Oracle\product\11.2.0\client_32
Choose the following components:
SQL*Plus
Oracle Call Interface (OCI)
Oracle Net
Oracle Services for Microsoft Transaction Server
Oracle Administration Assistant for Windows
Oracle Provider for OLE DB
Oracle Data Provider for .NET
Oracle Providers for ASP.NET
Repeat above steps with the 64-bit installer. HOWEVER, change the "Software Location" to C:\Oracle\product\11.2.0\client_64
I got a memory error at this point, but chose to ignore it since I know there is enough
Ignore the error "OracleMTSRecoveryService already exists"
Now that the install is done, just need to tweak a few things.
Make registry changes to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\MTxOCI
OracleOciLib should be oci.dll
OracleSqlLib should be orasql11.dll
OracleXaLib should be oraclient11.dll
Makesameregistry changes to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSDTC\MTxOCI
Create or copy a new tnanames.ora in C:\Oracle\product\11.2.0\client_32\network\admin
Create or copy a new tnanames.ora in C:\Oracle\product\11.2.0\client_64\network\admin
Reboot!
You should now see OraOLEDB.Oracle as a provider under Linked Servers\Providers in SSMS
Right-click this provider, then Properties, then tick the box for "Allow Inprocess"
You can now create linked server through the GUI or T-SQL
Good luck!
