Link server SqlServer 2008 R2 and oracle 8i

Hi,
I have many days trying to link a oracle 8i 8.1.6.3 AIX with SQLServer 2008 R2 64 bits.
I tested with ODAC: 11,10 and 9.
Any one can tell me any suggestions to do it? I read many articles and blogs and says not possible to do.
Some guys wroted in blogs articles that was succesful, but when I do the step by step dont work.
We cant update the oracle 8i 8.1.6.3 AIX, we cant shut down the system.
Kind regards.

Just an update to this problem as I have had time to get round to looking at it again.
Installed MSSQL Server 2008 on a Windows XP 32 bit virtual PC.
Installed Oracle Instant Client, copied the TNSNAMES.ORA from the server above.
Set the Environmental Variables and rebooted.
Same BIDS package as in the original problem.
Only 8 seconds to run and transfer 39062 rows, roughly 4883 rows a second!
I am very curious about where the problem lies.
Is it a problem with the Oracle 64 bit drivers but while within the BIDS environment it should be using the 32 bit drivers?
The package did not run any faster when using MS SQL Agent to run the package where it would have used the 64 bit drivers.
I think I will leave this Virtual XP setup running on our Virtual Server Server to do the transfers.
I'd still like to know what the problem is and how to fix it.
So if anyone else has the same problem and solves it please post the answer here.
Thanks in advance
Simon

SQL Server 2005 64 bit and Oracle 9

Hi,
I have a situation which involves SQL Server 2005 64 bit and Oracle 9 32 bit,
I have a requirement that involves creating Stored Procedures from Oracle 9 which will call tables from SQL Server 2005 64 bit, with operations involving 'Select' 'Insert' 'Update' and 'Delete'.
it works fins, except when attempting to search for an SQL Server 'varchar' value, wher no mapping is done
though the Oracle sees the field as 'varchar2'
can anyone please advice on this
thanks
Basel

I think you're somehow not getting a resuklt because you're query doesn't return any data.
Why the fiealdA=pat=parameterA construct? Wouldn't it just work if you changed it to fieldA=parameterA?
Also, can you not just define parameterA as a varchar to make them match?
What if you do "select * from (<your query without where>) a where a.fieldA = :parameterA"
While not efficient, it would make the filtering occur in Oracle and maybe that will let you see the problem in native Oracle land and then reuse the solution in your orginal query. If that doesn't work, drop the where clause and inspect the data closly and hardcode a simple where without using PL*SQL or bind variables.

Linked Server SQL 2008 64 bit Windows Server 2008 64 bit

Hello there,
I'm trying to access my customers Oracle database with a SQL Linked Server. The error I get is:
Cannot create an instance of OLE DB provider "OraOLEDB.Oracle" for linked server...
I did the following steps:
1. Installed Oracle client 10g with a custom installation and selected everything.
2. Created a tnsnames.ora
dev =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dijkora01)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = dev)
3. Tested this with tnsping dev, which said that the connection is OK.
4. Activated 'Allow inprocess' for my OraOLEDB.Oracle provider for the linked servers in my SQL Server Management Studio.
5. Created a new linked server with:
Linked Server: IAP
Provider: Oracle Provider for OLE DB
Product name: Oracle
Data source: dev
In the security tab I activated 'Be made using this security context'. When I now press 'OK' I get the above error message.
Can someone help me with this?

Windows 7 Enterprise 32-Bit
Installed the version 12 for 32 bit ODAC and it worked. The key is to Install as Administrator once it is unzipped.
Was able to set up Listener then
Was able to set up ODBC using the ODAC. Connect MS Access 2010 to the Oracle views.
Then, tried to install the 64 Bit onto Windows 2008 Server.
It locked up during installation both times.
Installed ODAC without an error.
However, the ODBC setup will not provide a list of the servers in the ODBC TNS Service Name listbox for Server 2008.
In Windows 7, it populates the TNS Service Name.
The list box in Windows 2008 is empty.
Do you know what would cause that?
The .ORA file scrips look the same on Windows 2008 as they do on Windows 7 except it does not have the (server = Dedicated) argument.
Thanks.

Sorry again, I am new on any kind of forum, so i am learning now, following is the error massage generated by SQL Server. and its not
an architecture problem, i had just included my complete architecture to be more informative while asking for the solution or suggestion. My real problem is T-SQL, i think and its related to Distributed queries raise in SQL Server in Oracle Link Server.

Hi DianaWeb,
It's glad to hear that your problem is resolved by changing the windows authentication into mixed authentication and use 'sa' user, namely an SQL Server authentication.
I believe the user name and password in the Netbean are for SQL Server Authentication to connect to SQL Server. The windows authentication you typed is not a valid SQL Server Authentication, that was why the connection failed.
In any case, if you want your J2EE project connects to SQL Server using Windows authentication(credentials of the user running Tomcat/Jboss where your application is deployed). Just build your JDBC URL like this:
jdbc:sqlserver://localhost;integratedSecurity=true;
See
Can I connect to SQL Server using Windows Authentication from Java EE webapp?
If you have any question, feel free to let me know.

Windows 2000 Advanced Server Service Pack 2 and Oracle 8.1

Hy,
I've got Oracle 8.1.6 instaled over an Windows 2000 Advanced Server user as a web server. Yesterday I updated it with the service pack 2 for windows 2000.
When I restarted the server after the install, the Oracle database services didn't start. They stay "Starting" but didn't finish to start. I tried to start them again but they were locked. I couldn't stop/restart them.
I had to uninstall the SP2. Then it works OK.
Is there any known problem with Oracle 8.1.6 and the SP2?
Thanks

When Oracle installs itself, it usually replaces one or more Windows system files with its own versions. Your SP2 installation probably replaced those files with originals and Oracle got confused.
The only solution I can think of is to install all the necessary SPs first and then Oracle (when possible).

SQL Server Express 2008 R2 and Windows 8.1 (Standard)

I recently re-engineered the backend of a legacy Access 2003 application because we knew that going forward we were going to loose the replication capability in Access. This is a small, departmental app, so the new SQL Server Express 2008 R2 backend is
hosted on a robust Windows 7 system. I tested the implementation with both Windows XP and Windows 7 clients running the updated Access 2003 frontend and everything worked great.
We are now in the midst of a company-wide upgrade to Windows 8.1 and I'm having issues. The legacy frontend works fine with Access 2013 (full version) when run locally on the Win7 machine, but I can't get any of the new Win 8.1 clients to connect to the
SQL database using the Access 2013 Runtime module. I CAN create ODBC connections to SQL Server from the clients and they test successfully, so I think I have a valid SQL connection to the Win 7 box.
To recap: old clients were WinXP Pro with Office 2003 Pro, new clients are Win 8.1 (non-Pro) with Access 2013 Runtime module.
Any ideas?

Hi ,
Glad to hear that you have found the solution. Thank you for coming back and let us know the result:)

Oracle 64bit Server (From JD Edwards) and oracle 32 bit client showing ORA:12560 "TNS: protocol adapter error "??

I installed 64bit Oracle successfully and was able to connect to DB using SQL Developer and sqlplus (Oracle E1local and TNSListener is up and running). I installed Oracle 32bit client and copied both tnsnames.ora and sqlnet.ora files to C:\app\Administrator\product\11.2.0\client\Network\admin. But if i am trying to access DB through Oracle 32bit client (thru cmd as sqlplus /sys as sysdba or thru sqlplus , it is throwing ORA:12560. "TNS: protocol adapter error ". (Both 62bit server and 32 client on same VM machine - Windows 2008 R2 ). I directly executed sqlplus from "C:\app\Adm\....client\bin", but it is still throwing same error and because of this JDEdward installation is not able to find if any database is running or not.!
My environment variables order: %PATH% = C:\app\Administrator\product\11.2.0\client\bin;c:\Oracle\E1Local\bin; I have seen all the previous threads and try setting ORACLE_HOME and PATH variable using CMD and tried accessing the database, but it fails all the time.
Please help me with the problem. Thanks in advance.

Intel(R) Embedded Server RAID Technology II and Oracle VM Server

Hi There
This is a head's up for anyone installing on a beast with the above mentioned on-board raid controller.
You have to use the Intel Setup CD to configure the raid. When you use the raid's bios to setup raid, the bios assign a name to the raid that confuse/brakes dmraid. I don't think you can set the raid's name in the bios. When you use the Intel CD you can configure the raid and you can edit the name of the raid. Pleas note, no spaces and no funny characters like #,%,@, in the raid name.
If you don't use the Intel CD, the bios/dmraid create a name that changes every time you reboot the server, I think this is due to spaces and the funny characters. So install will work but after the first reboot, dmraid won't find the raid and your raid configuration won't work.
Ciao
Nardus

Hi,
Thank you for the information. As you said from the behavior it seems that the build-in drivers of Windows Server Technical Preview will not work with the specific motherboard hence the RAID1 cannot work well.
I'll log the issue down.

Build a dicom server with web logic and Oracle Multimedia DICOM

Its it possible, build My own dicom server...only using web logic + java + Oracle Multimedia DICOM ?

Hi,
In The LDAP side you need to increase:
MaxPageSize - This value controls the maximum number of objects that are returned in a single search result, independent of how large each returned object is. To perform a search where the result might exceed this number of objects, the client must specify the paged search control. This is to group the returned results in groups that are no larger than the MaxPageSize value. To summarize, MaxPageSize controls the number of objects that are returned in a single search result.
Default value: 1,000

SQL 2008 Problem Calling an SP on an Oracle 10G Linked Server

Hi everyone
I've read through a number of posts on many sites about this issue but haven't found anything that has helped me so far. The machine I'm using is running Microsoft SQL Server 2008 64bit and the linked server I've created to Oracle 10G is using OraOLEDB.Oracle. If I test the connection in SQL Management Studio it succeeds and for any queries I have using OpenQuery to select from the Oracle DB I have no problem getting results.
The Oracle 32bit client and 64bit client versions are installed on the machine.
My problem is that I need to exec an Oracle SP which in turn inserts into various Oracle tables. I previously had this all working fine on 32bit SQL Server 2000 installation connected to Oracle 10G. Using the same code in SQL Server 2008 I get the following error:
Msg 7357, Level 16, State 2, Line 1
Cannot process the object "{CALL INTF.INTF_TW_PO_REQ_INTERFACE.MAIN(NULL, 15.000000, 0.000000, 'BLPO0099998', 'BLPO0099998', '', '', 39804, 21883, 'BLPO0099998', 249, 1, 950, 'Main', 190506, 37336, '1', TO_DATE( '20090706','YYYYMMDD' ), TO_DATE( '20090706','YYYYMMDD' ), 'INCOMPLETE',37336, {RESULTSET 1, P_Success})}". The OLE DB provider "OraOLEDB.Oracle" for linked server "ORACLE" indicates that either the object has no columns or the current user does not have permissions on that object
The call is made by the following piece of code in SQL:
SET @execCmd = N'SELECT
P_Success
FROM
OPENQUERY( ORACLE, '''+ @oracleCmd + ''')';
EXECUTE (@execCmd);
Where @oracleCmd = {CALL INTF.INTF_TW_PO_REQ_INTERFACE.MAIN(NULL, 15.000000, 0.000000, ''BLPO0099998'', ''BLPO0099998'', '''', '''', 39804, 21883, ''BLPO0099998'', 249, 1, 950, ''Main'', 190506, 37336, ''1'', TO_DATE( ''20090706'',''YYYYMMDD'' ), TO_DATE( ''20090706'',''YYYYMMDD'' ), ''INCOMPLETE'',37336, {RESULTSET 1, P_Success})}
I also tried using the below snippet from another post I found and got no joy either.
declare @result varchar(255)
exec ('BEGIN
?:= your_SP_Name(''arg1'', ''arg2'', etc);
END;
',@result OUTPUT) at your_LinkedServerName;
select @result;
OLE DB provider "OraOLEDB.Oracle" for linked server "ORACLE" returned message "ORA-06550: line 3, column 7:
PLS-00222: no function with name 'INTF_TW_PO_REQ_INTERFACE' exists in this scope
ORA-06550: line 3, column 1:
PL/SQL: Statement ignored".
I can't figure out why it doesn't work in SQL 2008 when it worked fine in SQL 2000 - PLEASE HELP!
Thank you
Alida Hope

Why development on 10g and production on 8i? Either both should be 8i or both should be 10g.
If you will keep production on 8i and development on 10g then you cannot stop such errors as there are features that are enabled by default in 10g and both the versions have very big differences.
Just go ahead and install 8i.

Linked server issue using SQLNCLI versions on SQL 2008 & 2014

Hi all,
Our product creates databases on a sql server 2008 instance and creates linked servers between them to use distributed queries.
This looks like: "EXEC sp_addlinkedserver 'linkDatabaseA', '', 'SQLNCLI10', '.', NULL, NULL, 'DatabaseA'"".
Distributed queries from second database to DatabaseA work fine in this scenario.
As we want to support both SQL 2008 and SQL 2014 in the next product version, I changed this to SQLNCLI11 as the provider
and tested on SQL 2008 after installation of the SQLNCLI11 driver.
This resulted in following error message:
Msg 468, Level 16, State 9, Line 7
Cannot resolve the collation conflict between "Latin1_General_CI_AS" and "SQL_Latin1_General_CP1_CI_AS" in the equal to operation.
This is very suprising as the SQL Server 2008 instance and both DB's have "SQL_Latin1_General_CP1_CI_AS" as their collation sequence.
Then I tried the opposite, installing SQLNCLI10 on SQL 2014. This gave exactly same error! Using SQLNCLI11 went fine ofcourse.
Generation sp_addlinkedserver statements with correct driver based on SQL version, I'd rather not do (some of the calls are
generated in SQL from settings in other db tables which are also used for external connx) and adding COLLATE to the queries also
has consequences like performance degradation. Adding collate on SQL 2014 with SQLNCLI10 as linked server provider results in
following error:
Msg 7399, Level 16, State 1, Line 1617
The OLE DB provider "SQLNCLI10" for linked server "linkDatabaseA" reported an error. Access denied.
Msg 7301, Level 16, State 2, Line 1617
Cannot obtain the required interface ("IID_IDBCreateCommand") from OLE DB provider "SQLNCLI10" for linked server "linkDatabaseA".
Q: Is there any way that SQLNCLI11 can be made to work for linked servers on SQL2008 (preferred solution) or SQLNCLI10 on SQL2014?
Thx for any feedback.
Regards, Jouke

Hi Sofiya,
Thx for replying.
For the deployment reasons mentioned above, I would prefer to use only one SQLNCLI version in both 2008R2 & 2012/2014 scenario's. Most preferred would ofcourse be SQLNCLI11 as this is the latest.
This would mean that I'd like to be able to configure linked server in SQL2008R2 using SQLNCLI11 driver.
I would expect that it would be downward compatible with SQLNCLI10 for all client usage, including linked server, which in essence is one SQL DB doing client access to another SQL DB either on same server instance or another. I suspect it requests DB
metadata from remote DB in order to make decisions and this seems not to work in my setup. If this metadata API is part of the public API, this could indicate that medadata API has been broken in SQLNCLI11 (heavy speculation on my part here!), which could
also affect other usage (eg. linked server between SQL2008(R2) and SQL2012/2014 instances, (I'll try to set this up and test this, might take a few days. If someone is volunteering, below are db table schemes and query, update @datasrc to point to remote sql
server instance)).

Hi Jouke Numan,
According to your description, I install SQL Native Client 11.0 OLE DB Provider in SQL Server 2008R2, and as you post, create two database on the same instance with collation in server default, then create Linked Server with SQLNCI11.0.
When I run the query statement, it can execute well. It also do not occur the collation conflict. I still recommend you check the collation of server, database, or column and so on.
SQL Server Native Client 11.0 provides OLE DB support to applications connecting to SQL Server versions 2005, 2008, 2008R2, 2012. So for the deployment reasons, you can choose the only SQLNCLI11.0 in both SQL Server 2008R2 and SQL Server 2012/2014.

Linked Server [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

Hi I have SQL2012 installed on my local machine and have also installed MySQL 5.6.23 installed with a test database.
I also have my SQL connector installed and MYSQL ODBC Driver 3.51.
Which happily connects to the Mysqldb.
The Datasource Name : mySQL conn
TCP/IP Server : localhost and Port :3306
User root
with pwd
On the SQL side I have used the following
EXEC master.dbo.sp_addlinkedserver
@server = N'MYSQLSRV',
@srvproduct=N'mySQL conn',
@provider=N'MSDASQL',
@datasrc=N'mySQL conn'
However when I try to selet using open query
SELECT * FROM OPENQUERY ( [MYSQLSRV], 'SELECT * FROM students' )
it comes back with
OLE DB provider "MSDASQL" for linked server "MYSQLSRV" returned message "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified".
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "MYSQLSRV".
I cant understand what I have done wrong . Any help in this would be great as Ive hit a bit of a brick wall

Hi Robert3975,
In addition to other post, please also note the following things.
1. If you use the 32-bit driver on a 64-bit machine, please run the 32bit version of "odbcad32.exe" by running "c:\Windows\SysWOW64\odbcad32.exe"
from Start/Run menu and
create your ODBC DSN. However, for the 64-bit driver, use c:\windows\system32\odbcad32.exe to create your ODBC DSN. For more details, please review this similar
thread.
2. Expand the folder Providers under Linked server directory in SSMS and go to properties of MSDASQL provider and configure it properly as described in this blog:
Creating Linked server to MYSQL from SQL Server.
