DATABASE LINK FOR SQL SERVER

Hi all,
We are running SAP 4.7C with oracle database. For other oracle (non-sap) we are using DBCO to get/put data. Now we have to do the same in SQL server also. In addition to SAP standard table we are sending data of customer table (Z & Y series). Can anybody guide me how to send / receive data using bapi/rfc or some other method.

Hi!
For using native-SQL with MSSQL database you have to make your database requests from application server resides on windows platform. So, your basis people have to set up one more windows-based application server instance. There is no impact on backend R/3 database.

Oracle 11G Linux ( Oracle Database Gateway for SQL Server 11.1.0.6.0. )

Hi,
I am tring Gateway for SQL Server ..
I want to Select Oracle Database Gateway for SQL Server 11.1.0.6.0 at the time of installation, but It is not coming in the Avaliable Components List..
Is there any prerequisite for SQL server ?
Any Help please ?

Are you following the "Step Through the Oracle Universal Installer" section under
http://download.oracle.com/docs/cd/B28359_01/gateways.111/b31043/sqlserver.htm#CCHEDECC
?

Problem with "Database Gateway for SQL Server"

Hello,
i am testing the different technologies for connecting an oracle database with a sql-server database.
The way using 10g-generic-connectivity with ODBC works fine, but the 11g-DG4MSQL makes problems.
Environment:
Server PEGASUS (32bit Windows Server 2003 R2 SP2) with Oracle Database 10g Release 10.2.0.4.0
Server OBELIXUS (32bit Windows 2000 Sp4) with MS-SQL-Server 2005
On PEGASUS i have installed the gateway in a new oracle home directory:
"D:\oracle\product\10.2.0\db_1" => home directory of 10g
"D:\oracle\product\11.1.0\tg_1\" => home directory of the gateway

How mentioned above, the access from oracle to sqlserver using MSSQL(10g hsodbc.exe) works fine.
But when trying to acces the sqlserver using MSSQLDG (11g dg4msql.exe) I get the following error:

At first your configuration is not really correct.
=====================================================
In the LISTENER.ORA from 10g, you must only refer to the database and hsodbc 10g
D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
(SID_DESC =
(GLOBAL_DBNAME = INTEGRAT)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(SID_NAME = INTEGRAT)
(SID_DESC =
(SID_NAME = MSSQLTEST)
(PROGRAM = D:\oracle\product\10.2.0\db_1\bin\hsodbc)

(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = pegasus.cursor.de)(PORT = 1521))
===========================================================
Then you have to create a new listener (new name) in the gateway oracle_home on a different port than instance database:
D:\oracle\product\11.1.0\tg_1\network\admin\listener.ora
SID_LIST_LISTENERGTW =
(SID_LIST =

LISTENERGTW=
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = pegasus.cursor.de)(PORT = 1522))
To start it, use the command below:
D:\oracle\product\11.1.0\tg_1\bin\LSNRCTL start listenergtw
===========================================================
D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora:
match the DG4MSQL with the listener on 1522 port
HSODBC match with binary10g on listener 1521 port
MSSQLDG =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PEGASUS)(PORT = 1522))
(CONNECT_DATA =(SERVICE_NAME = DG4MSQL))
(HS = OK)
MSSQL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = PEGASUS)(PORT = 1521))

Try to configure and let me know your feedback

Creating a database link to SQL server

Hi All,
How can I create a database link from Oracle9i Enterprise Edition Release 9.2.0.1.0 DB to MS SQL Server database.
Thanking You
Regards Lakmal

It depends on your requirements.
You can use either Generic Connectivity or Transparent Gateways.
More information can be found here:
http://www.oracle.com/technology/products/gateways/index.html

Using DB Link for SQL Server

Hi All,
When I query the SQL server table from Oracle using DB Link, it works fine for any table:
select * from testtable@DBLINK test -- This statement works fine because I am giving * i.e. all columns
But when I try to query specific columns like
Select test.status from testtable@DBLINK test
then it gives me error ORA-00904: "test.Status invalid Identifier", I can see this particular column when I query the testtable for all of the columns.
I don't know what to do.
Thanks

You need to use quoted names. SQL Server data dictionary stores names in same case they were entered while Oracle in upper case. So when you issue
Select test.status from testtable@DBLINK test Oracle parser will look for column STATUS while on SQL Server side it could be stored, for examle, as Status or status. Check column names on SQL Server side and use quoted names. Assuming column name is Status:
Select test."Status" from testtable@DBLINK test SY.

Multibyte issue in database link with sql server

Hi Gurus,
Greetings!!!
I need to transfer data from Microsoft SQL Server 2005 to Oracle DAtabase 10g(AL32UTF8 characterset). I achieved it using Heterogeneous Connectivity. I can now issue queries but unfortunately i got an issue in displaying multibyte characters. I thought of using another Tool that can display multibyte data but it did not help. I even tried setting the initialization parameter HS_LANGUAGE to different characterset but still not able to display. Kindly help and advise how to resolve the said issue.
Many Thanks in Advance,
Benjie

What is the exact issue you're talking about?
Can you explain it or show us a sort of it with a sample output?
MS SQL Server is not our daily bread so we may not know how it works with Oracle and what problems are there in their interconnectivity, but we may tell you what may be the reason of a behavior that causes the issues for your purpose.
Bye Alessandro

Strange problem with an Oracle database link to SQL Server

Hi gurus,
Please help me on this problem.
We have an Oracle 10R2 database link to a SQL Server 2000 database. I can select count(*) from The_SQL_Server_Table@myOracleLink, and I can describe The_SQL_Server_Table@myOracleLink, but I cannot select Column1 from The_SQL_Server_Table@myOracleLink! I am getting the ORA-00904: "COLUMN1": invalid identifier error.
Could anyone tell me what is wrong here? By the way, the same user name can select all the columns in The_SQL_Server_Table through ODBC from the client app. But I need the DB link to work with some Oracle stored functions.
Thank you!
Ben

I am getting the ORA-00904: "COLUMN1": invalid identifier error.
Could anyone tell me what is wrong here? By the way, the same user name can select all the columns in The_SQL_Server_Table through ODBC from the client app. But I need the DB link to work with some Oracle stored functions.
Thank you!
Bennotice "COLUMN1" is different from "Column1"

How to create a database link to SQL Server from a RAC environment

We have a 4 node RAC running 11.2.0.3 binaries on 64-bit linux.
Grid owns the listener named listener.
Oracle owns the database.

Thanks all! But I tried to configure and I am getting
TNS-01201: Listener cannot find executable /u01/app/oracle/product/11.2.0.3/dbhome_1/bin/InfoEdb10 for SID InfoEdb10
Listener failed to start. See the error message(s) above...
So! What I did was
1. Configure the odbc from the OS (only one node) and create the DSN and its odbc files. connectivity works from Operating Systems.
2. Create the listener entry (under GRID) user.
3. Create the remotedb.ora file under $ORACLE_HOME/hs/admin
--- Here is listener.ora file
LISTENER_NODE1_TG =
   (DESCRIPTION_LIST =
    (DESCRIPTION =
       (ADDRESS = (PROTOCOL = TCP)(HOST = devrac-a-01-vip.cssd.pitt.edu)(PORT = 1549)(IP = FIRST))
       (ADDRESS = (PROTOCOL = TCP)(HOST = devrac-a-01.cssd.pitt.edu)(PORT = 1549)(IP = FIRST))
SID_LIST_LISTENER_NODE1_TG =
   (SID_LIST =
       (SID_DESC =
         (SID_NAME = InfoEdb10)
         (ORACLE_HOME = /u01/app/oracle/product/11.2.0.3/dbhome_1)
         (ENVS = "LD_LIBRARY_PATH=/u01/app/oracle/product/11.2.0.3/dbhome_1/lib")
         (PROGRAM = InfoEdb10)
any help is appreciated

SAP and Database Encrption on SQL Server 2005 or 2008

Hi. I searched as best I could for any existing threads on this topic, and could not find any, so I hope it's OK to raise a new one.
We're running SAP ECC 6.0 on a SQL 2005 database. Database size is around 3.3 TB, with Trans Log of about 550GB, storage is HP EVA.
I've been asked to report on how Database Encryption would impact our systems, both from the perspective of enabling it initially and then how it would affect performance going forward.
I've read a few White Papers, for example:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/4ab89e84-0d01-0010-cda2-82ddc3548c65?QuickLink=index&overridelayout=true
.. and from what I'm reading, it looks like I would want to be moving to SQL Server 2008 as a first step. Does anyone have any experience of implementing SQL encryption for a SAP database, either in 2K5 or 2K8?
All comments or help will be welcomed.
Thanks
Steven Clark

DB Link to SQL Server (11gR2 64-bit Windows 7)

Without going into all the gruesome details, it is mostly straightforward to set up a DB Link to SQL Server from an Oracle 10 instance on 32 bit Windows 7. However I simply cannot get the link to work on 11gR2. I tried the simplistic ds4odbc interface and the more complex SQL Server gateway. Nothing works. The connection always times out. Has anyone been able to create a SQL Server DB link from 11gR2 on Windows 7? (The Oracle instance is 32 bit. The OS is 64 bit). I know Win7 is unsupported at present.

Hi,
first of all you need to check the ODBC connectivity between Oracle and SQL Server and the Data source,try to load data from oracle to Sql Server to check the ODBC connection is working properly and then create database link from sql server to oracle ,you can create stored procedures in SQL server to get data from Oracle to sql server or Oracle PL/SQL Packages to data from sql server to Oracle Database
To setup ODBC and datasource
see this link
http://www.databasejournal.com/features/oracle/article.php/3442661/Making-a-Connection-from-Oracle-to-SQL-Server.htm
and then create link server in sql server after you test connenction with oracle

Permissions needed for sql server job to execute stored procedure on linked server?

Hi all
I have a job step which attempts to call a stored procedure on a linked server.
This step is failing with a permission denied error. How can I debug or resolve this?
The job owner is sysadmin on both servers so should have execute permission to the database/proc I'm calling, right?
The error is:
The EXECUTE permission was denied on the object 'myProc', database 'myDatabase', schema 'dbo'. [SQLSTATE 42000] (Error 229). The step failed.
My code is:
EXEC [LinkedServer].myDatabase.dbo.myProc
Also tried:
SELECT * FROM OPENQUERY([LinkedServer], 'SET FMTONLY OFF EXEC myDatabase.dbo.myProc')
With the same result.
Any help appreciated.

The job owner may be sysadmin on the remote server. The service account for SQL Server Agent may not. And it is the latter that counts, since the it the service accounts that logs in and impersonates the job owner. But the impersonation inside SQL Server
does not count much in Windows, and it is through Windows connection is made to the other site.
One way to resolve this is to set up a login mapping for the job owner. The login mapping must be for an SQL login on the remote server.
You can verify the theory, but running this query from the job:
SELECT * FROM OPENQUERY([LinkedServer], 'SELECT SYSTEM_USER')
By the way, putting SET FMTONLY OFF in OPENQUERY is a terrible idea. This has the effect that the procedure is executed twice. (Unless both servers are SQL 2012 or higher in which case FMTONLY has no effect at all.)

How could I create a "Linked Server" link from SQL Server 2008R2 64-Bit to Oracle Database 11.2 64-Bit?

How could I create a "Linked Server" link from SQL Server 2008R2 64-Bit to Oracle Database 11.2 64-Bit?
Let's say the SQL Server and Oracle Database are in the same Company Internet Network.
I have the code, but I do not know how to use it. Such as what is System DSN Name? Where could I get it. What does it look like?
Do I need to install any Oracle Client Software in order to link from SQL Server to Oracle? Or SQL Server has the built-in drivers installed already that I can directly create a Linked Server from SQL Server to Oracle?
I need to know details. Thanks.
USE master
go
EXEC sp_addlinkedserver
     @server  = '{Linked Server Name}'
    ,@srvproduct = '{System DSN Name}'
    ,@provider  = 'MSDASQL'
    ,@datasrc  = '{System DSN Name}'
EXEC sp_addlinkedsrvlogin
     @rmtsrvname = '{Linked Server Name}'
    ,@useself  = 'False'
    ,@locallogin = NULL
    ,@rmtuser  = '{Oracle User Name}'
    ,@rmtpassword = '{Oracle User Password}'

You need an OLE DB provider for Oracle. There is one that ships with Windows, but it only supports very old versions of Oracle. Oracle has an OLE DB provider that you can use. I don't know if it's part of Oracle Client or how it is bundled.
You should not use MSDASQL or any DSN.

Is it possible to have different authentication mode for SQL Server Database Engine and corresponding SQL Server instance?

Hi,
I have installed the x64 SQL Server 2008 R2 Express with default settings and run MBSA 2.3 (using default settings too). It shows three SQL Server instances: MSSQL10_50.SQLEXPRESS, SQLEXPRESS and SQLEXPRESS (32-bit). For the first, authentication
mode is Windows, for the rest two - mixed. Here https://social.msdn.microsoft.com/Forums/sqlserver/en-US/03e470dc-874d-476d-849b-c805acf5b24d/sql-mbsa-question-on-folder-permission?forum=sqlsecurity question
about such multiple instances was asked and the answer is that "MSSQL10.TEST_DB
is the instance ID for the SQL Server Database Engine of the instance, TEST_DB", so in my case, it seems that MSSQL10_50.SQLEXPRESS is the instance ID for SQL Server Database Engine of the SQLEXPRESS instance.
I have two questions:
1) How can it be that SQL Server DB Engine instance has different authentication mode than corresponding SQL Server Instance?
2) Why 32-bit instance reported although I installed only 64-bit version?
Also, this https://social.technet.microsoft.com/Forums/security/en-US/6b12c019-eaf0-402c-ab40-51d31dce968f/mbsa-23-reporting-sql-32bt-instance-is-running-in-mixed-mode-when-it-is-set-to-integrated?forum=MBSA question seems to be related to this
issue, but there is no answer :(.
Upd: Tried on clean Windows 8 installation and Windows 7 with the same result.

Because I DO NOT want the three people who will be having access to the production SQL Server to also have access to the primary host ProductionA. Since I have to allow them to RDC into the box to manage the SQL Server, I figure why not create
a separate VM for each one of them and they can RDC into those instead.
Does this make any sense?
Any tips are greatly appreciated. The main reason for doing this is because the three people who will be accessing the box, I need to isolate each one of them and at the same time keep them off of the primary ProductionA.
Thanks for your help.

Hello M,
Since you dont want the 3 guys to have access to Production machine A.You can install SQL Server client .By client i mean SQL server management studio(SSMS) on there local desktop and then create login for them in SQL Server.Open port on which your SQL server
is running for three of the machines so that they can connct.Now with SSMS installed on each machine each can connect to SQL server from there own machine.
I would also like you to be cautious with giving Sysadmin privilege to all three of them ,first please note down what task they would do and then decide what rights to be provided.
Your option will also work but you need to create 3 VM for that .Which is more tedious task.
Hope this helps

Can I use Microsoft SQL Server Management Studio version 11.0 to write SQL queries for "SQL Server Compact 4.0 Local Database"

Hi, Can I use Microsoft SQL Server Management Studio version 11.0 to write SQL queries for "SQL Server Compact 4.0 Local Database" ?
When I use Connect Object Explorer, the "Connect to Server" dialog box which pops up has only 4 selections in the Server Type Drop Down List. They are Database Engine, Analysis Services, Reporting Services & Integration Services. I have read
somewhere that there should be a compact database option. but I do not see it.
What I would like to do is use free form SQL Queries against the tables in "SQL Server Compact 4.0 Local Database" .
Once I have validated these queries, then I will use them in my Visual Studio 2012 C#, ASP.NET application. I created the Local Database using Visual Studio 2012 for use by my application.
Thank you for your help..

Hello,
With SSMS 2005 we have had the Option to work with SQL CE database files, but not with higher Version of SSMS.
You can use the free SQL CE Toolbax instead; see
