Linked Server (Oracle 9i)

P: n/a

Hello all,

Having problems connecting to an Oracle 9i database from within
SQL/Server 2000 using the Security/Linked Servers feature.

Server1 (SQL/Server)
-----------
Windows Server 2003, Standard edition
MS SQL/Server 2000
Oracle 9i Client kit (OLEDB & ODBC) & Enterprise management tools
Microsoft ODBC for Oracle
Oracle OLEDB
MDAC 2.8 RTM

Server2 (Oracle)
-----------
Windows 2000 - Advanced Server
Oracle 9i database (v9.2.0.1.0)
Two nodes clustered using Microsoft cluster manager. (Nodes are
DATABASE01 & DATABASE02 - Cluster is WMCLUSTER)

When I try to connect to the linked server in Enterprise Manager I get
the following error messages.

Error 7399 OLE DB provider 'MSDAORA' reported an error. Authentication
failed.

OLE DB error trace [OLE/DB Provider 'MSDAORA'
IDBInitialize::Initialize returned 0x80040e4d: Authentication
failed.].
From within Query analyzer I get a slightly different message
reporting that the username/password are incorrect.

dbcc traceon(7399)
select * from TURLIVE..SONICA.INV_LOC
Server: Msg 7399, Level 16, State 1, Line 3
OLE DB provider 'MSDAORA' reported an error. Authentication failed.
[OLE/DB provider returned message: ORA-01017: invalid
username/password; logon denied
]
OLE DB error trace [OLE/DB Provider 'MSDAORA'
IDBInitialize::Initialize returned 0x80040e4d: Authentication
failed.].

I know the username/password combination is correct and I can use
these from with Oracle enterprise Manager with sucess.

TURLIVE is the name I've given the linked server, SONICA is the name
of the schema on the Oracle database and INV_LOC is a valid table.
TURLIVE is also the name of the database instance on Server2.
Steps taken so far

Install Oracle client tools (Enterprise Manager, Net manager etc) on
Server1.

Setup an entry in TNSNAMES.ORA to the cluster that has the Oracle
database. e.g.

TURLIVE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = WMCLUSTER)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = TURLIVE)
)
)

This works fine, I can connect via Oracle Enterprise manager and I can
TNSPING WMCLUSTER, DATABASE01 & DATABASE02.

Configured an ODBC source to TURLIVE.

On Server1 I've configured the linked server using the following SQL.

sp_addlinkedserver 'TURLIVE', 'Oracle', 'MSDAORA', 'TURLIVE'
sp_addlinkedsrvlogin 'TURLIVE', false, 'sa', 'sonica','******'

(password blanked)

I then rebooted Server1

The properties of the new linked server are:

Product name = Oracle
Data Source = TURLIVE
Provider String = blank

I've modifed the registry on Server1 as instructed by a Microsoft KB
article.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\MTxOCI \

OracleXaLib = "oracleclient8.dll"
OracleSqlLib = "orasql8.dll"
OracleOciLib = "oci.dll"
Still no luck. Can anyone please point out he bleeding obvious? :-)
Thanks in advance
As an aside, has anyone ever configured a linked server to an Oracle
Rdb (Previously DEC Rdb running on OpenVMS and DEC UNIX) database?
Are there any HOWTO guides for this type of connectivity?

Cheers
Dave.

Are you sure you are connecting to sql server with sa username? (check in
enterprise manager registration properties if you are using sa or windows
autentication)
try to use
sp_addlinkedsrvlogin 'TURLIVE', false, null, 'sonica','******'

Excuse me for my bad english.

Hi David,

Make sure you are using the login/password. Since error says it is a
"Anthentication error". And also make sure you are using the right
Provider.
