Connecting to Windows SQL server from Unix Oracle Server

How can I connect to Windows MS SQL server from Unix Oracle Server? What installation or package will I need?

Two options:
1) Do a search on "Oracle Transparent Gateways" and/or "Heterogenous Services". These are products that are designed solely to connect to other databases from Oracle.
2) Use a type-4 JDBC driver for SQL Server, installed and running in the JVM of your Oracle server. I'm assuming your Oracle database is sufficiently recent to be java-enabled here.

Have you moved from Unix/Oracle to Windows/SQL Server

I am looking for people that have moved from Unix/Oracle to Windows/SQL Server...
Would you do it again ?
Did you save money ?
Were you using Zones to virutalize on Unix ?
Did you gain or loose overall Performance ?
Have you had to perform a recovery on SQL Server ?
Have you done a recovery in Oracle ?
Were you using Rman ?
Which worked better ?
We are going through an analysis of does it really make sense, save money and effect performance to move from a strong unix/oracle environment to a MS/SQL environment.

Hi,
All our R/3 legacy systems are Windows/Oracle.
All the new systems (BW, SRM, CRM, XI) are Windows/MSSQL.
It was an order from the management to make the switch because of the high prices of Oracle licences.
The official motto is now Oracle on Unix only and SQL server on Windows only.
We get the same level of performance as with Oracle, but we, old SAP Oracle grumpy admins, are much more comfortable with Oracle admin than SQL server admin.
imho, SQL server may seem simplier but it is much easier to look under the hood whith Oracle.
We have to reinvent the wheel and it's kind of frustrating but we will cope with it...
I would say that SQL server is not a good choice for BW usage because there is a lot more litterature on BW database optimisation for Oracle than MSSQL.
The official SAP class does not speak at all about SQL server but has several chapters on Oracle...

Connect to MS-SQL Server from a Oracle 10g running under Solaris

Hi,
I have the following problem. I want to access a MS-SQL server from an Oracle database (10g Enterprise licence) that is running on Solaris.
After googling a while, the following questions arise:
- Is it correct that the Oracle Transparant Gateway for the SQL Server is not available on Solaris platforms (but only on Windows)?
- Is it right, that the second possibility to solve this problem is to use an SQL-Server odbc driver for Solaris and access the SQL-Server over ODBC? And: Is this feature included in the Enterprise licence?
- If yes, which driver is good and cheap ;-)?
- Is there any other way to solve this problem?
Thanks
Aron

I believe the Transparenet Gateway for SQL Server is available on Solaris. The problem is that you need a Unix based ODBC driver which you will also need to pay for.
We had this same problem and decided to run a windows based Heterogeneous Services gateway and routed through it instead of using the SQL Server transparent gateway. The Heterogenous severives gateway is NOT an add on product (as is Transparent Gateway). The drawback would be performance as I would expect the native MS SQL transparent gateway to perform better, but in our case it worked acceptably.

How to run import from Unix Oracle 8.0.5 database with Windows Oracle client?

How to run import from Unix Oracle 8.0.5 database via network with Windows Oracle client? Is it possible? When I try to do it Oracle client just hangs... If not which ones are compatible Aix or Solaris to Unix or it must be a Unix client to connect to Unix Oracle database. Thank's for any help.

Hi,
In our project we are using this type. Since in this project server in UNIX(DEC) and client is running on windows. We have created a listener which always listen requests from client and doing the according to the request.
Step1. create a request table, where u are inserting ur request.
step2. create PRO*C proram, which is listening request on the table. If there is any request, call the imp (executable). This is happening on server side.
Benifit. U can make a request from cleint and ftp the file client sit.
Are u interested in more details and code, pls send a mail to me

How to prevent from starting oracle server every time i start windows?

I have winXP professinonal, and i would like to know how to prevent from starting oracle server every time i start windows. Because it really slows starting the windows. Thanks

The scripts above seems to work as intended with no errors and do indeed stop my five XE services. I created the second script to start them and they do indeed start and are listed as "Started" in the Services panel aferwards.
My XE installation has the 5 services set up to start automatically.
I was happy to find the script above because I did not know the starting order and using the XE shortcuts for "Stop Database" and "Start Database" just seemed to cause sqlplus to receive ORA-12514 "listener does not currently know of service..." after trying to use them to restart the database. Using the scripts above seems to leave me with a different error.
I am pretty sure I eliminated my 9i listener and it is no longer listed in my Services panel or the registry.
Restarting the laptop does start the services correctly, and now I am on to a more pressing JDBC error, so if I get a chance to use the script again, I will post my results. Thanks.

Using archivelog and control file from other Oracle server

I am still bothered with my backup process.
I have 2 AIX boxes (same model, say A and B); both have BAAN 5 and Oracle 10g R2 on. Right now my colleague insists to use the export pump (cold backup) from Prod Oracle server (A) to restore the Oracle server on Box B. The Prod server has the archivelog mode turn on. But it will miss any transaction data from import pump till the crash point of Box A. So this is my confusion.
Can I pass the control files and archivelog files form Box A (prod server) to Box B and use them to restore the Box B as the latest Prod server? How?
I tried to convince them to use the RMAN backup? But not successful?
I think the best way is probably to use the Oracle Data guard. However, there is always one concern to my manager and colleague, that such process will cause the data on the restored server (failover, Box B) not recognizable by the BAAN, which define the objects (tables).
Thanks

Performing a logical backup is not useful to restore to the point of failure. The only valid and available option is a hot backup/archivelog mode. Your recovery manager backup perform a controlfile and redologfile backup, so those can be restored at the destination. You must take care of the way you perform the backup, and ensure the paths where your backup is being deposited are visible by the second node. A shared storage with same mount points is suitable in this case. A tape robot configured at both nodes is also a suitable solution.
Recovery manager perfoms a controlfile and spfile restore, too. This rman command perform the action:
SET DBID <DBID of the database,for which you want to restore the controlfile>;
RESTORE CONTROLFILE FROM <name_of_backupiece_which_contains_the_controlfile backup>';
I don't see any problem on the recovery manager side, and technically speaking, on the Oracle side it is perfectly possible to restore your database at a remote location. I don't know what happens on the BAAN side, if you are required to have it configured to be operative on the target node. You could try to clone your database at the node B, configure BAAN and prepare the proceduere in case of failure.
Configuring a dataguard is also a recomended action. So it is to think about Cold Failed Over clusters. I have recently performed a CFC configuration with BAAN. No problem it works smoothly.

Call procedure with MS SQL from linked Oracle server

I have a procedure on a remote server that I can call from SQL*PLUS
set serveroutput on
declare rez varchar2(99); msg varchar2(99); begin radar.test('AL25',rez,msg); dbms_output.put_line('Rez='||rez);
dbms_output.put_line('Msg='||msg);
end;
it gives me the neccessary result.
But I need to call the same procedure with MS SQL from a linked Oracle server, I'm trying to do it through openquery for a while, but no success yet.
Can someone tell me what is the right syntax for that query in OPENQUERY?

Have you tried configuring Oracle Heterogenous Services/ Transparent Gateway? This would let you link Oracle to SQL Server via a database link which should solve your problem.

Cannot connect to ag-sql-listener from Secondary Server

Greetings,
I have a Azure VM setup with two SQLs SQL1 and SQL2, they run a High Availability setup with SQL-AG-Listener as the listener name.
My problem is currently is that if I have SQL1 as Primary, when I'm logged into SQL2 I can't use the SQL-AG-Listener as target to get the Primary server. However I can do a connection to SQL1 directly.
On the Primary server I can however use the SQL-AG-Listener and will get the local server as expected.
The SQL-AG-Listener works perfectly from outside the local network of Azure.
===================================
Cannot connect to ag-sql-listener.
===================================
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider:
Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)
===================================
I don't know what else I can try and do now. I have run through most of the issue handling as I can, all from Opening all ports to and from both the SQL servers on the domain level. Made sure that named pipes, TCP/IP connections on both SQL servers was enabled.
As I can run towards them from the outside, and can connect to them directly on name from the SQL servers themselves, then I know that they can take remote access.
Any idea on what I might be missing would be welcome.

Yes, I know I had a typo in the above, where the ag-sql-listener was typed wrong.. It was ofcause SQL-AG-Listener.
But it is still a problem. I don't know if there are some DNS things that can be done, as it seems this is a problem from within the same subnet and not from outside.

How to connect to an oracle database server from a linux server?

Hi,
I am a total newbie to oracle. At my work, I only know that there is a server with an oracle 10g database set up.
I was provided with the hostname, oracle sid, port, username and password but i don't know how to connect to it, log on to it and do things on the database.
Can anyone give me a pointer on how to get started (like how to log on to the server and start doing some simple things. )
Any help is appreciated :)
Thank you

Goto your local Oracle install directory and then goto folder NETWORK/ADMIN
cd ${ORACLE_HOME}/network/admin
do you see a tnsnames.ora file there? If you edit that file in your favorite editor, you would hopefully see some entries there already setup. See if one of those entries contain the hostname, sid, port that was given to you. if it does, that name is what you will use:
$ sqlplus username/password@name_of_tns_entry_you_found_aboveif not, then just duplicate an existing entry and change the relevant settings for your database, give it a new name and use it to connect.
alternatively you can also use the "Net Configuration Assistant" application.

Hi Affar2k,
According to your description, we need to verify if there is no network issue and the Sqlclient version is older than .NET 4.5. You can try to connect to the Windows Azure SQL database via SSMS and check if it can run well. When you
connect to the SQL Azure database via ADO.NET, you need to verify that the server name and passwords are right in the connection string.
For more information, you can review the following article about how to connect to Windows Azure SQL Database using ADO.NET.
