MSSQL 2005 Can't Query Linked Oracle Server

Hello All:

I am trying to create a server link between MSSQL 2005 and Oracle 9.2.0.7.
I can successfully execute the sp_addlinkedserver
and  sp_addlinkedsrvlogin
s function but when I attempt to execute a query
against the Oracle server such as:

SELECT * FROM OPENQUERY(SD03, 'SELECT * FROM V$VERSION')

I receive the following error:

Msg 7403, Level 16, State 1, Line 1
The OLE DB provider " MSDAORA" has not been registered.

I then go to the C:\Program Files\Common Files\System\Ole DB folder and
execute the following:

regsvr32 msdaora.dll

which returns success and rerun the query, the error persists.  I ran
Component Checker to confirm the MDAC is 2.82.

What do I need to execute queries against the Oracle server from MSSQL 2005.

Thanks,

You need to install the Oracle Client software and reboot.  Also you should
use the OleDB provider from Oracle, since the MS provider was not kept
up-to-date with later versions of Oracle.

Hello David:

I have the Oracle 9i client installed and tested successfully against the
Oracle server.  I rebooted the MSSQL 2005 server, executed the same query
and received the same error:

Msg 7403, Level 16, State 1, Line 1
The OLE DB provider " MSDAORA" has not been registered.

Would I be better off trying an ODBC connection?  I thought the OLE
connection would be best for migration of Oracle data to MSSQL 2005 server.

Thanks for your speedy response.

Mike

No.  OleDB is required for linked server.  Try Oracle's OleDB provider.
