I run a query using an Oracle Linked Server.
This seems to run forever.
SELECT * FROM LinkedServer..Schema.View WHERE TN= '2034561295'
...and any other field in the where clause work fine.
SELECT * FROM LinkedServer..Schema.View WHERE SPID= '8088'

I need to link some data from SQL Server 2005 with Oracle 10 data.One way is to link Oracle server to SQL Server and use ROWSOURCE forretrieving data.What other ways for joing data from both databases exist ?Can I do it from SQLCRL VB - Stored Procedure ? If yes, what objectsshall I use for opening database and running an sql ?
When I tried to import system.data.oracleclient, it was not available. Do I need to install anything for being able to use it ?
Thanks a lot.

Basic description:
We have developed a solution that sends data from SQL Server to an Oracle server as the result of a stored procedure called by a job that runs every minute. While this development worked fine in our test environment, after moving it to production it ran successfully the first minute, but the second minute the stored procedure hung, and the process could not be killed. In order to stop the process I had to stop both the SQL Agent and the MSDTC services.
Our SQL Server box:
SQL Server 2000 Standard Edition SP4
Windows 2003 Server R2 SP1
Our Oracle box:
Test: Oracle 9.2.0.6
Production: Oracle 9.2.0.4
To setup the SQL box, I did the following:
1) Install Oracle Client Tools version 10.2.0.1
2) Restart Server
3) Modify the registry as follows:
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSDTCMTxOCI] "OracleXaLib"="oraclient10.dll" "OracleSqlLib"="orasql10.dll" "OracleOciLib"="oci.dll"
4) Modified the PATH variable so that all references to SQL Server appear in front of Oracle path references
5) Added the linked server via sp_addlinkedserver '<tns name>','Oracle','MSDAORA','<tns name>'
6) Added linked server logins via sp_addlinkedsrvlogin '<tns name>','False','<SQL user>','<Oracle User name>','<password on oracle>'
7) Changed the registry for MSDTC to match this:
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSDTC]
"AllowOnlySecureRpcCalls"=dword:00000000
"FallbackToUnsecureRPCIfNecessary"=dword:00000001
"TurnOffRpcSecurity"=dword:00000001
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSDTCSecurity]
"NetworkDtcAccess"=dword:00000001
"NetworkDtcAccessAdmin"=dword:00000001
"NetworkDtcAccessClients"=dword:00000001
"NetworkDtcAccessTransactions"=dword:00000001
"NetworkDtcAccessTip"=dword:00000001
"XaTransactions"=dword:00000001
"DomainControllerState"=dword:00000000
"AccountName"="NT Authority\NetworkService"
"NetworkDtcAccessOutbound"=dword:00000001
"NetworkDtcAccessInbound"=dword:00000001
8) Stopped and restarted services in the following order:
1) MSDTC Stop
2) SQL Server Stop
3) MSDTC Start
4) SQL Server Start
The stored procedure:
In a single transaction, the stored procedure compares a production table against a logging table. If a record exists in the production table that is not in the logging table, a record is inserted into logging table, and a record sent to Oracle via an INSERT INTO OPENQUERY('INSTANCE','SELECT Column1, column2, column3,... FROM SCHEMA.TABLE')
SELECT column1,column2,column FROM SQLTable
This stored procedure has worked just fine for us in test, to either the test or production Oracle boxes, but it now fails, and hangs, in production to either the test or production Oracle boxes.
Additionally, I can run the following query via Query Analyzer from our test box to both the test Oracle and production Oracle and it runs successfully (this is NOT used in our stored procedure code, but is presented here as an indication that I think there is something wrong with the settings on our production SQL box):
SELECT * FROM OPENQUERY('INSTANCE','SELECT * FROM SCHEMA.TABLE')
When I run this same query via Query Analyzer on our Production SQL box, to either the test Oracle or production Oracle, it hangs, and I have to kill the process, and restart the MSDTC service.
Other queries that hang are:
SELECT * FROM SERVER..SCHEMA.TABLE
Additionally, I noticed that when I used this method to kill the process I would see errors like the following in the Application Event Log on the SQL box:
The XA Transaction Manager attempted to perform recovery with the XA resource manager. The XA resource manager reported that recovery was unsuccessful. DSN = MTxOCI.Dll.
Since I figured this was an aborted transaction still residing in the MSDTC log file, I would stop the MSDTC service, delete the MSDTC log file, reset the MSDTC log, and then restart the MSDTC service in order to prevent this error from occurring.
Not ALL queries from the production SQL box to production and test Oracle boxes fail. I can get results returned for this query:
SELECT COLUMN1, COLUMN2 FROM SERVER..SCHEMA.TABLE
I've been scouring the internet for about a week now, and I've run out of ideas on what to check on the production SQL box. Any suggestions would be greatly appreciated.

I am new to sqlserver.
1)I created a linked server to a oracle database, works fine. Now I am writing queries, using "Query Desgner", when I do a "Add table" linked server tables do not appear. Is this a limitation. I can get around the problem by creating a view.
2) When I use "Microsoft OLE DB Provider for Oracle" for linked server, some times connection seems to get lost. On one occassion, the next day it was fine, it re-established itself.
Any ideas thnx.

Microsoft .NET Framework 2.0.50727.42
Operating System 5.2.3790
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.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "OraOLEDB.Oracle" for linked server "SomeServer".
This is how I set up my Linked server:
Provider: "Oracle Provider for OLE DB"
Product Name: SomeServer
Data Source: SomeServer
Provider String: "Provider=OraOLEDB.Oracle;Data Source=SomeServer;User Id=MyLogin;Password=MyPassword"
The query I run is:
Select * from [Someserver].[schema or database]..[tbl_name]
Any help??? What am i missing?

Hi,
I have an issue with one of my production servers. I have a few production servers, and they all have the same objects. I do not want to create custom objects for each one, rather keep them all standard.
However, due to environment issues, I have one which does not have any linked servers.
I have a proc which queries either locally or across the linked server depending on the value of a switch. I want to install this proc on the server with no linked servers but it obviously fails.
I can guarantee the proc will never be called with the switch 'on' on that particular server. We still want to install this proc and call it with a switch of 0.
Please can somebody come up with something really clever.
The proc goes something like this:
CREATE PROC WhatEver @Switch int
AS
IF @Switch = 1
BEGIN
SELECT * FROM LinkedServer.Db.dbo.MyTable
END
ELSE BEGIN
SELECT * FROM dbo.MyTable
END
Thanks in advance

Hi:
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?
Thank you very much.

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

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.
Anyone have thoughts/suggestions? TIA!

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.
Thanks

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?
Any help, input or suggestions would help.

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';

Hello,
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?
I am at a lost as to what to try next...
Any information would be greatly appreciated,
Thank you,

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. Testing from the 9i client produces a successfullconnection.I then opened SQL-Server and created a new Linked Server with thefollowing setup:Name - PYR_LinkProvider - Microsoft OLE DB Provider for OracleProduct Name - PYRData Source - PYR (9i Service Name)Provider string - MSDAORAI get the unspecific 7399 error that OLE DB provider MSDAORA reportedan error, trace 'Initialize returned 0x80004005'I've searched through the archives, checked all of the relevantMicrosoft articles I could find, and still have no idea what is wrong.SQL-Server reports that the provider is registered in the system, but Ican't figure out what I'm missing.Help or a guide for troubleshooting would be much appreciated.Tim

Hello,
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.
The Column WEBVORZUGSTYP is defined as number.
Any ideas?
Regards,
Ralf

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?
