Cannot create an instance of OLE DB provider "OraOL

在SQL SERubiconVE大切诺基 2010 Evoque2下用Windows 身份验证的登陆名创制了多少个做客ORACLE数据库的链接服务器xxxxx,测验成功,木有失水准,可是任何登陆名使用该链接服务器时,报如下错误:

消息 7302,级别 16,状态 1,第 1 行

Cannot create an instance of OLE DB provider "OraOLEDB.Oracle" for linked server "xxxxxx".


此刻亟需在“服务器对象”——>“链接服务器”——>“访谈接口”下,找到OraOLEDB.Oracle选项,单击右键采取属性,然后在做客接口选项下勾选“允许进度内”(Allow inprocess)。就可以缓和地方难题,一时候,大概必要再行新建此链接服务器。

Ran into this issue where the linked server would work for users who were local admins on the server, but not for anyone else. After many hours of messing around, I managed to fix the problem using the following steps:

  1:Run “dcomcnfg.exe”. Navigate to “Component Services -> Computers -> My Computer -> DCOM Config”.

  2:Open the properties page of “MSDAINITIALIZE”.

  3:Copy the “Application ID” on the properties page.

  4:Close out of “dcomcnfg”.

  5:Run “regedit”. Navigate to “HKEY_CLASSES_ROOTAppID{???}” with the ??? representing the application ID you copied in step #3.

  6:Right click the “{???}” folder and select “Permissions”

  7:Add the local administrators group to the permissions, grant them full control.

  8:Close out of “regedit”.

  9:Reboot the server.

  10:Run “dcomconfig”. Navigate to “Component Services -> Computers -> My Computer -> DCOM Config”.

  11:Open the properties page of “MSDAINITIALIZE”.

  12:On the “Security” tab, select “Customize” under “Launch and Activation Permissions”, then click the “Edit” button.

  13:Add “Authenticated Users” and grant them all 4 launch and activation permissions.

  14:Close out of “dcomcnfg”.

  15:Find the Oracle install root directory. “E:Oracle” in my case.

  16:Edit the security properties of the Oracle root directory. Add “Authenticated Users” and grant them “Read & Execute”, “List folder contents” and “Read” permissions. Apply the new permissions.

  17:Click the “Advanced Permissions” button, then click “Change Permissions”. Select “Replace all child object permissions with inheritable permissions from this object”. Apply the new permissions.

  18:Find the “OraOLEDB.Oracle” provider in SQL Server. Make sure the “Allow Inprocess” parameter is checked.

  19:Reboot the server.
