Linked Server To Oracle Causes SQL Server Instance To Crash
Mar 3, 2007
When running a linked server to Oracle using the MSDAORA driver using in-process option checked, I'm getting the following error:
"A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)"
This then causes the instance to crash.
In the Event Log, it shows:
SQL Server is terminating because of fatal exception c0000005. This error may be caused by an unhandled Win32 or C++ exception, or by an access violation encountered during exception handling. Check the SQL error log for any related stack dumps or messages. This exception forces SQL Server to shutdown. To recover from this error, restart the server (unless SQLAgent is configured to auto restart).
When using the out-of-process, it shows the column names in the query results window, but doesn't show any data then immediately in the message window it shows:
Msg 7399, Level 16, State 1, Line 2
The OLE DB provider "MSDAORA" for linked server "smtest" reported an error. Access denied.
Msg 7350, Level 16, State 2, Line 2
Cannot get the column information from OLE DB provider "MSDAORA" for linked server "smtest".
We're using:
SQL Server 2005 SP1 with hot fixes (9.0.2153) 32-bit on 64-bit o/s Windows 2003 R2 Standard x64 Edition Sevice Pack 1
We use lots of linked servers to Oracle on other servers, and can't find anything different on this one.

I have the OraOLEDB.Oracle provider installed to the (C:oraclexe) directory.
I am having problems querying from linked oracle server. When i setup oracle as a linked server and purposely enter an incorrect password the query i run tells me i have an incorrect password. So it at least knows that. when i set the correct password and run a query I get this error:
(i replaced the real server name with "someServer".)
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "OraOLEDB.Oracle" for linked server "SomeServer" reported an error. The provider did not give any information about the error.

i want to run a transaction across mulitpule instances of sqlserver with out linked server.distributed trnasaction can do it with link server , can it do it with out linked server.
We have oracle linked server created on one of the sql server 2008 standard , we are fetching data from oracle and updating some records in sql server . Previously its working fine but we are suddenly facing below issue.
Below error occurred during process .
OLE DB provider "OraOLEDB.Oracle" for linked server "<linkedservername>" returned message "". Msg 7346, Level 16, State 2, Line 1 Cannot get the data of the row from the OLE DB provider "OraOLEDB.Oracle" for linked server "<linked server name>".
I am using Windows 2003 server and Sqlserver 2005 by the use of Linked server , I made a connection to Oracle 10g after that I am importing records from Oracle to sqlserver 2005. When I made tnsnames.ora in sql machine , it worked fine but when i am using tnsnames file from oracle server then i fiired importing procedure it returns below maintain error :
OLE DB provider "MSDAORA" for linked server "BI_ORACLE_LS" returned message "Unspecified error".
OLE DB provider "MSDAORA" for linked server "BI_ORACLE_LS" returned message "Oracle error occurred, but error message could not be retrieved from Oracle.".
Msg 7311, Level 16, State 2, Line 1

Ok, so these are the facts: My company wants to implement a BI, the warehousing company we used sold us panorama on sql server. Our database is on oracle. They were proposing this method: a) Link oracle server, copy oracle tables to sql database and then build cubes from sql database. The operation will be made only once a day at night. I don't like it so make it like this: b) Build cubes directly from linked oracle server. As it is not good to build directly from tables and views (because they could change between processing dimensions), I used materialized views (or snapshots) and some views on slow modifying tables. Problem: Oracle snapshots must be refreshed and that is done in oracle with a procedure. My question is: How can I run an oracle procedure directly from sql server? I want to create a job that will refresh the oracle snapshots and process analysis database after that. I know I can use OPENQUERY to return queries from oracle but I want to execute a script. Solutions?
Another way was by doing it in a command line. I asume there is an special job feature that can run programs.
I configured SQL Server 7.0 by Linked Server to a Oracle db. What I found was I could select data from SQL Enterprise Manage but fail to insert any data through Query Analyst from SQL Server to Oracle. The platform for the SQL Server is NT 4.0 SP6.
Could you point out what I missed while inserting data from Query Analyst to Oracle?
Hi,I have an Oracle (8.1) & a SQL Server 2000 database withProduction data. There are situations when I need data from both thedatabases. My first choice was to link Oracle to SQL and run DTSovernight. But this would have a 1 day latency not to mention the timeit would take.1. Has any one tried real time access via Linked server to Oracle?How good is the performance?2. The Oracle db is fairly big, so I'm kinda not in favor ofcopying the whole thing over into SQL overnight. Is there an easierway to just get only the changed records from Oracle?3. Is there a better solution to this?4. Lastly, if I use OPENROWSET or OPENQUERY, can I dynamicallychange the SQL that you pass it? e.g. can the query accept aparameter?Thanks in advanceSudhesh
Hello,I have a linked server to oracle 7.1 from SQL 2000. when I try toexecute simple select statement which returns one row of data usingopenquery is not fetching the data. After 30 minutes SQL Queryanalyser is hanging. This is happening on the production server and itis working from last 6 months. I have tried by deleting and recreatingthe linked server, but no use. Please helpThanks,Regards,Pardhasaradhy

Anyone using a SQL Server Linked Server to access Oracle RDB on a VMS/Alpha? What connection are you using? What is reuqired? I am using OLE DB Provider for ODBC to access an ODBC connection I setup using the Oracle ODBC driver for Oracle RDB 2.1 and it seems slow and limited. You can only use the OPENQUERY method to access data, etc.
We're having some trouble connecting SQL Srvr2005 to Oracle (10g) in our 64-bit environment. We have Oracle's 32-bit Ole Db provider installed and have been able to use that in SSIS to connect and return some data running in 32-bit debug mode (as long as the query isn't long, complicated or using parameters =)
However, we have some hefty queries that we need to gather some data and want to put them in a stored proc on Oracle and call it through SSIS. We tried adding our Oracle DB as a linked server and are getting some errors. I've tried the following code replacing the provider with 'OraOLEDB.Oracle.1', 'OraOLEDB.Oracle' as well as 'MSDAORA':
EXEC sp_addlinkedserver
'ORA_TSTW', 'Oracle',
'OraOLEDB.Oracle.1', 'TSTW'
EXEC sp_addlinkedsrvlogin 'ORA_TSTW', false,
'user', 'lituser',
'pw'
select * from openquery(ORA_TSTW, 'select * from lituser.customer')
We keep getting the error for each of the providers we try. I've tried it in Management Studio as well as in an Exec SQL task (with debug set to 32-bit) to no avail.
Cannot create an instance of OLE DB provider "OraOLEDB.Oracle.1" for linked server "ORA_TSTW".
I've checked and the MSDAORA.dll is registered in both C:Program Files (x86)Common FilesSystemOle DB as well as C:Program FilesCommon FilesSystemOle DB.
If we can't where we can call an Oracle stored proc, we were thinking of just using a script task to connect to Oracle and retrieve the data we need, but I have a feeling performance this way would be degraded.
I installed the Oracle client on my computer, and I can connect to oracle databases using SqlPlus, however when I try setting up the linked server I get the following error after I try executing a query.
I have used Linked Servers to hook up to an Oracle 9i database in SQLServer 2000. I can see all the Tables and Views when I look in thelinked server section. I can also run the following SQL statement :Select *from Orcldb..SYSTEM.CrossTabSaveSitesand get a return result. The problem I realize is that some of thetables are going to be quite larger and I can't wait for SQL Server todownload all the data and parse it itself, so I tried to use apassthrough query like so :SELECT * FROM OPENQUERY(OrclDB, 'SELECT * FROMSYSTEM.CrossTabSaveSites')Unfortunately this gives me the error message :Server: Msg 7321, Level 16, State 2, Line 1An error occurred while preparing a query for execution against OLE DBprovider 'MSDAORA'.[OLE/DB provider returned message: ORA-00942: table or view does notexist]There is also the issue of speed. It takes about 15 seconds to comeback to me to tell me that the table/view doesn't exist, but sometimesit comes back immediately. Is this something with the userpermissions in Oracle? (Don't really know much about Oracle) It justseems like a very long time to wait just to let me know that the itemdoesn't exist.Any help would be greatly appreciated,-Jevon Thurlow
We have a linked server, which worked fine, but we have just changedthe collation sequence, in SQL-Server, fromSQL_Latin1_General_CP1_CI_AS to Latin1_General_CI_AS.Now trying to use the Linked server, we get the following message:"Error 7399: OLE DB Provider 'MSDAORA' reported an error. The providerdid not give any information about the error. OLE DB error trace [OLEDB provider 'MSDAORA' IDBInitialize::Initialize returned 0x80004005:The provider did not give any information about the error]."Ha anyone seen this before, because I am not sure why changing thecollation sequence, would affect the Linked Server
I need to push 40k rows daily to an Oracle database. I am on a Win2k Pro box with the 8.1 client and ADO 2.6 loaded. I've configured the linked server with the Oracle as well as the Microsoft provider and it takes over a minute to push just 24 rows, less than 100 bytes each, at it. Any suggestions?
Does anyone know how to link an Oracle (8.0.6.0) database to a MS SQL 7.0 db? I have set up the ODBC and it works with no problem. I can get tables from the oracle db and bring them into MS access with ODBC so I know that it is set up correctly. I just cant get visability to the db in a sql 7 environment. Any help or sugestion would be appreciated. Thanks -NES
Can someone please tell me what oracle software needs to be installed on a sql server machine that will link to an Oracle database on an NT4 machine.
Also can you also confirm if you have successfully executed an oracle stored procedure from sql server using the open query function. If yes, How? because I have read about people having prolems executing stored procedures with arguments using the OPENQUERY Function.
Anyone have any suggestion on increasing the performance going over a linked server? IS this connection persistent? Or does it establish a connection with each reference? Any other Providers for the connection other than Microsofts OLE DB Provider for Oracle? I imagine that building index's on the referenced oracle tables would help?
Hi,I have created a linked server to oracle, which works fine.But when I try and create a view joining the SQL table with the linked Oracle table, it only returns the primary key field in the Oracle table and nothing else.Anyone know why?ThanksN.B. I'm using SQL Server 2005 btw.
I have a SQL Server 2012 instance set up with a linked server to an Oracle Database. I need to build a stored procedure (single NVARCHAR(6) parameter in: @accountID) which executes a select statement against the Oracle DB.
Everything's working fine when testing with 'EXEC (''<oraclecodeblock>'') at LINKEDSERVERNAME' if I hard code the value of @accountID in <oraclecodeblock> but when I encapsulate it all within sp_executesql and attempt to parameterize @accountID it's throwing ORA-01722 'invalid number' errors on the Oracle DB. The parameterized value is NVARCHAR as are the account numbers.
Working: DECLARE @accountID VARCHAR(6); SET @accountID = '10842'; DECLARE @sql NVARCHAR(MAX); SET @sql = N'EXEC (''SELECT * from A.Accounts WHERE ID = ''''10842'''';'') AT LINKEDSERVER';
I have a problem which I have spent the whole day trying to resolve but with little success...
Here is the situation:
I installed the Oracle Client 9.x.x on to my production MS Windows 2003 Server running MS SQL Server 2005 Enterprise (I need to make a Linked Server connnection to an Oracle database). The problem is if I try to create the Linked Server, I get an "Oracle Client software not installed. You must have the Oracle Client software installed to create connection" message from SQL Server. This is frustrating because the software is installed and I am able to make queries through SQL*Plus to the Oracle Database...
Here is my checklist ---
1) the PATH variable on the Windows Server is set correctly to the proper ORACLE HOME directory (with proper /bin directories set as well) 2) I have an updated MDAC component installed 3) registry configuration are correct for Oracle 9i 4) created test Linked Server connections to various datasources (not Oracle)
I am assuming the tsnames.org file is set up correctly or I would be able to make queries from SQL*PLUS, is this assumption correct?
Hi,I am using MSSQL 2k, and I have a linked server set up to an Oracle RDBversion 7. It goes thru an OLE DB provider for ODBC drivers on a systemDSN, which is using an Oracle RDB ODBC driver version 3.0.2.The problem occurs when I send a query that returns zero rows - queryanalyzer just does not complete nor return. This problem is not seenwhen there are rows being returned.I ran a trace and this is the error message I get-:Non-interface error: OLE DB provider MSDASQL returned an incorrectvalue for DBPROP_CONCATNULLBEHAVIOR which should be eitherDBPROPVAL_CB_NULL or DBPROPVAL_CB_NON_NULLAnybody who experienced this before has a solution?Thanks,Lawrence
I'm currently trying to establish a linked server to an Oracledatabase.Setup:Connecting to 8x version of OracleUsing 9i client tools (Net Manager)SQL-Server 2000Windows 2000I installed the Oracle 9i client tools, and set up a Service for theOracle connection.

I created a linked server to Oracle on SQL-Server 2005. I have stored the remote login username and password in the security settings (option "...Be made using this security context" in the Security tab of the Linked Server Properties.
The "Test connection" function works fine, but a select doesn't for every table the user owns. What we found out is: if the table consists only of columns defined as varchar2, the select works. As soon as the table contains only one column defined as number (without scale and precision), it doesn't work. The error displayed is:
The OLE DB provider "MSDAORA" for linked server "NEXUS_FVADM" supplied inconsistent metadata for a column. The column "WEBVORZUGSTYP" (compile-time ordinal 2) of object ""FVADM"."AKZ"" was reported to have a "DBTYPE" of 130 at compile time and 5 at run time.
I have a SQL Server 2005 with a linked server to an Oracle RDB 6.0, using the Microsoft OLE DB for ODBC provider. I would like to select some rows from the Oracle RDB and then Update those specific rows afterwards. Whenever I try to do this in a transaction (BEGIN TRAN) I get an error "Driver not capable". Is there any way to do this in a single transaction?
Hello. I have the following problem: I set up a linked server in SQL Server 2000 to Oracle with Oracle OLEDB provider. I see all the tables in the linked server so the connection is successful but when I tried to select from some remote table, most often I get the following error: Server: Msg 7356, Level 16, State 1, Line 1 OLE DB provider 'OraOLEDB.Oracle' supplied inconsistent metadata for a column. Metadata information was changed at execution time. MOREOVER, selecting from some of the tables, returns other errors: * Server: Msg 7320, Level 16, State 2, Line 1 Could not execute query against OLE DB provider 'OraOLEDB.Oracle'. or: Server: Msg 7317, Level 16, State 1, Line 1 OLE DB provider 'OraOLEDB.Oracle' returned an invalid schema definition. All these errors are very strange to me!
I set up a linked server to the same Oracle database but with Microsoft OLE DB provider for Oracle. And everything just works perfect! (I would use this provider but it does not support distributed transactions so I can't do all my job.)
I just can't understand why the Oracle OLEDB provider is not working properly.
The same situation is happening with another PC in different LAN, with different SQL server, different Oracle database and so on.
