为了使用Com+事务,我逼迫使用ORACLE9i,安装了9.2,可在.net 下的microsoft ole db for oracle 却无法使用,提示是:程序初始化失败....另外,我是先卸载的8i,在按的9.2.
我找到如下资料:
Oracle9i Release 2 Data Provider for .NET 9.2.0.4.0
下载文件
Oracle Data Provider for .NET 9.2.0.4.0（包括 ODAC）
附注
－ 如果使用 Microsoft 企业服务/分布式事务处理协调器进行分布式事务处理，则需要 用于 MTS 的 Oracle 服务。
－ 如果您有依赖于旧 Oracle Home 版本的应用程序并且未经 Oracle9i Release 2 Home 版本认证，则请不要在以前的 Oracle Home 版本（例如 Oracle8i）上安装 ODP.NET。例如，Microsoft OLE DB provider for Oracle (MSDAORA) 可能无法与 Oracle9i Release 2 客户端协同工作，因为该供应程序尚未做相应的测试。
可我不是很能搞懂她具体说的意思.是说Microsoft OLE DB provider for Oracle (MSDAORA) 可能无法与 Oracle9i Release 2 客户端协同工作,还是说认证后就可以,那是的话,如何认证.

Problem Description ------------------- When running an application that connects to Oracle and uses the Authenticated User privilege (such as Microsofts Internet Information Server (IIS)) via Oracles 9.2 client software and any of these programmatic interfaces 1. Oracle Provider for OLE DB 2. Microsoft OLE DB Provider for Oracle 3. Oracle ODBC Driver 4. Microsoft ODBC for Oracle 5. Oracle Objects for OLE (OO4O) you will receive one of the following errors: (1) Oracle Provider for OLE DB Error Type: Microsoft OLE DB Service Components (0x80070005) Access is denied. (2) Microsoft OLE DB Provider for Oracle Error Type: Microsoft OLE DB Provider for Oracle (0x80004005) Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed. Or Error Type: Microsoft OLE DB Provider for Oracle (0x80004005) Oracle error occurred, but error message could not be retrieved from Oracle. (3) Oracle ODBC Driver Error Type: Microsoft OLE DB Provider for ODBC Drivers (0x80004005) Specified driver could not be loaded due to system error 5 (Oracle in OraHome92). (4) Microsoft ODBC for Oracle 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) client software installation. You will be unable to use this driver until these components have been installed. (5) Oracle Objects for OLE (a) while using a GLOBAL.ASA file Error Type: Active Server Pages (0x0) An error occurred while creating object OraSession. (b) not using a GLOBAL.ASA file Error Type: Microsoft VBScript runtime (0x800A0046) Permission denied: CreateObject (6) Other miscellaneous errors (a) The Specified Module Could Not Be Found Solution Description -------------------- You need to give the Authenticated User privilege to the Oracle Home by following these steps: 1. Log on to Windows as a user with Administrator privileges. 2. Launch Windows Explorer from the Start Menu and and navigate to the ORACLE_HOME directory. 3. Right-click on the ORACLE_HOME folder and choose the "Properties" option from the drop down list. A "Properties" window should appear. 4. Click on the "Security" tab on the "Properties" window. 5. Click on "Authenticated Users" item in the "Name" list (on Windows XP the "Name" list is called "Group or user names"). 6. Uncheck the "Read and Execute" box in the "Permissions" list (on Windows XP the "Permissions" list is called "Permissions for Authenticated Users"). This box will be under the "Allow" column. 7. Check the "Read and Execute" box. This is the box you just unchecked. 8. Click the "Apply" button. 9. Click the "OK" button. 10. You may need to reboot your computer after these changes have been made. Re-execute the application and it should now work. Explanation ----------- If you install Oracle9i Release 2 (9.2.0.1) on a computer running Windows with an NTFS partition, the contents of ORACLE_HOME directory will not be visible to users who are authenticated on that machine. These permissions were not set properly when the software was installed. Applications that were working fine with previous versions of Oracle software will stop working when they upgrade to Oracle 9.2. NOTE: The application will continue to work if the user has logged onto the machine as an Administrator. Any application that is using the Authenticated User privilege will not work. A notable example would be IIS which might service some of the requests based on the Authenticated User privileges. To demonstrate the problem in further detail, you can log on to the operating system as an authenticated machine user. You wont be able browse the contents of the ORACLE_HOME directory demonstrating your inability to load any Oracle DLLs or make a connection.

针对上面的描述,我也做了相关工作,可问题未解决.
网友回答：
用 oracle oledb provider
引用:
提示是:程序初始化失败....
这个错误的原因我以前遇到过,很有可能是你的驱动程序没有在注册表中注册,具体办法是:
将program files\common files\system\ole db\中相应的注册表文件的信息写入注册表
例如我的系统是win2000+oracle8i,运行mtxoci81_win2k.reg即可
oracle ole db privider for .net 可以使用,但是我在使用的过程中,偶尔会随机出现一些
System.Data.OleDb.OleDbException: 未指定的错误: E_FAIL(0x80004005),至今未找到原因,换用microsoft的提供程序后问题解决
