链接服务器

在SQL SERVER 2008 R2下用Windows
身份认证的登录名创建了一个访问ORACLE数据库的链接服务器xxxxx,测试成功,木有问题,但是其它登录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”.

 

此时需要在“服务器对象”——>“链接服务器”——>“访问接口”下,找到OraOLEDB.Oracle选项,单击右键选择属性,然后在访问接口选项下勾选“允许进程内”(Allow
inprocess)。即可解决上面问题,有时候,可能需要重新新建此链接服务器。

老外给出了一个解决这个问题的步骤,相当详细严谨,几乎面面俱到。可以作为参考学习的好资料:

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_ROOT\AppID\澳门新萄京,{???}” 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.
