System.Data.OracleClient requires Oracle client software 8.1.7 or later __oracle

In the development with vs.net2005+oracle9.2, in the local test can be passed, but not on the server (copy the site, publish the site are not), the specific content of the error, did not write down, probably is: " System.Data.OracleClient needs Oracle client software 8.1.7 or later " online query for a long time also did not work, and then integrated online many methods, finally tested successfully, now share." The cause of the error: 1. Although the report is required to install the client 8.1.7 and above but not this, but. NET accounts do not have access to the Oracle/bin folder 2.windows2003 operating system installed in NTFS-formatted disk, if it is FAT32 there is no such problem, it seems ntf The S format is really good for security. Say less, or look at my solution. 1. Right--------sharing and security------security on the Oracle/bin folder-----Click the "Add" button to appear below the interface 2. Click on the "Advanced"----"Find Now" and select "Ntwork Service" in the account shown below (note: The IIS6 account in ASPNET is ntwork service; and in IIS5 is the ASPNET.) In short, in the search out of the account which one of these two accounts to choose which one, because I have not seen these two accounts coexist, haha, I guess we can not coexist.   This city's personal opinion does not represent Microsoft's opinion)----assigns all permissions to----OK. 3. In the "Computer Management" (Haha, if you do not know how to enter that there is no way to say)-----Double-click on the right side of the Administrators------The last step of the search out of the account to add. 4. Restart IIS.   You can enter "IISRESET" in "Run".   Note: These are set permissions, if you configure the above reported ORA-12154 errors, you need to configure "Net Configuration Assistant" on the server. Environment tested: Win2003 (NTFS) +oracle9.2+vs.net2005
