Asp.Net 连接Oracle数据库 出现"找到 Oracle 客户端和网络组件" 彻底解决方法!
本人用Asp.Net做的程序本地访问oracle数据库时,在自己机器上好好的能访问,但是当放到服务器时
就不能出现如下的错误:
"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. "
本人查询了CSDN发现不下二十人问过这个问题,但是没有一个人真正的给出了一个解决办法,但是项目马上就要交工了,问题还没有解决,最后请教我们公司的技术总监——”Oracle专家“终于搞定这个问题：
据我的理解：1.是在 Oracle 9.02i 版的问题，2.你的 ORACLE_HOME 路径所在的分区格式是：NTFS格式；解决方法 到Oracle\ora92 打开Ora92的－》属性－》安全,选Authenticated Users 看下面的属性 将Read and Execute 的勾去掉，然后又勾上，确定重新启动机器 ，ok 搞定，就是这么简单，
当然要避免这种问题，您可以这么做：不要安装Oracle9.02 或者不要安装在NTFS格式的分区

Problem Description ------------------- When running an application that connects to Oracle and uses the Authenticated User privilege (such as Microsoft's Internet Information Server (IIS)) via Oracle's 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 won't be able browse the contents of the ORACLE_HOME directory demonstrating your inability to load any Oracle DLLs or make a connection.
