Connect to SQL Server from Oracle

Does Oracle offer any connectivity to NON-Oracle databases such as SQL Server from within the Oracle database itself, similar to a database link ?

Yes, it's called Heterogeneous Connectivity. Basically how it works is you set up an ODBC data source on the Oracle server
and need to modify the tnsnames.ora and listener.ora files. Once you get it set up it works exactly like a dblink. You should be
able to find information on it in the Oracle manuals or from Metalink. There's also a Heterogenous Connectivity forum on OTN. If
you can't find anything let me know and I can send you some documents on how to set it up. I think the hardest part for you might
be finding a SQL Server ODBC driver for HP-UX.

Regarding the tns-12541 error in connecting to sql server from oracle

i need to create a database link from oracle on windows box to sql server.I configured everything but when i am trying to tnsping the sqlserver
it throws me an TNS12541 no listener error.
The listner status is up and the listener works

little confusion here, are you trying to tnsping sql server? tnsping is an Oracle utulity.
To acces sql server from Oracle you may use Transparent Gateway for Microsoft SQL - http://download.oracle.com/docs/cd/B19306_01/gateways.102/b14270/ch3.htm#sthref66 and Heterogeneous Connectivity - http://download.oracle.com/docs/cd/B19306_01/server.102/b14232/intro.htm#sthref33

Connecting ms sql server from oracle using db link

Hi,
Source : Oracle 11g on linux
destination : ms sql server 2005
i need to create the db link from oracle to ms sql server to view the tables , is it posibble without configuring the gateways( as looks like it is licenced product)
Please let me know any alternative to achive this
Thanks
PGR

There are 2 gateway - the commercial Database Gateway for Ms SQl Server which requires a license and the Database Gateway for ODBC which is for free. The license for DG4ODBC is included in your database license. You only need to install a suitable ODBC driver on your Linux box (for example use the MS SQl Server ODBC driver for Linux - details can be found here: http://www.microsoft.com/en-gb/download/details.aspx?id=36437 ). and then configure the gateway using the My Oracle Support Note:
How to Configure DG4ODBC on 64bit Unix OS (Linux, Solaris, AIX, HP-UX Itanium) to Connect to Non-Oracle Databases Post Install

No suitable driver when connect MS SQL server from Oracle 10g using JTDS

Hi,
I have developed a java servlet application connection to MS SQL using jtds-1.2.jar. I have try to deploy this application to Oracle 9ias and it works fine.
However, when I deploy the same application to Oracle 10g (10.1.2.0.2), I encounter this error - java.sql.SQLException: No suitable driver.
I have copy the jtds-1.2.jar to Ora10g/jdbc/lib, Ora10g/j2ee/home/lib and also the Ora10g/j233/OC$J_GENERAL/applications/sampleApp/sampleApp/WEB-INF/lib folder, and also setup the data source via the EM interface. The data-source.xml entry is as follows:
<data-source location="jdbc/ess" class="com.evermind.sql.DriverManagerDataSource" xa-location="jdbc/xa/essS" ejb-location="jdbc/ess" connection-driver="net.sourceforge.jtds.jdbc.Driver" username="scott" url="jdbc:jtds:sqlserver://202.xx.xx.xx:1433/sampleDB" inactivity-timeout="30" name="ess"/>
</data-sources>
Is there any configuration that I've forgotten to set?

Which I believe from what you have entered is:
Ora10g/j2ee/OC4J_GENERAL/applib
There's a general JDBC 3rd party driver set of documentation here:
http://download.oracle.com/docs/cd/B14099_11/web.1012/b14012/datasrc.htm#sthref592
This is not using jtds-1.2.jar but it shows how another set of 3rd party jdbc libs are used with the server.

How to connect to SQL Server from Forms 10g?

Hello all,
How do we connect to SQL Server database from Forms 10g?
In Oracle Metalink site they have suggested using Transparent Gateway for SQL Server as a solution.
But is there a way we can connect directly to SQL Server from Forms using an ODBC connection
without installing anything on the database server?
Pls help!
Regards,
Sam

Hello all,
I was able to connect to SQL Server from Oracle using Generic Connectivity (HSODBC).
Transparent gateway was not required.
Followed metalink note 109730.1
So, after I created a dblink to SQL Server, I created a synonym for the dblinked SQL Server table.
When I used the synonym as the table source in Oracle Forms, I got the following error while querying.
"ORA-02070 - ROWID is not supported in this context."
This is because Forms has an invisible ROWID field and when data is fetched from SQL Server table
no Rowid is fetched since SQL Server table doesn't have one.
Is there a way to overcome this issue or do we have populate the block manually using a SQL query ?
Pls suggest.
Regards,
Sam

How to connect to a Sql server from Oracle using db link

Hi All,
Does anybody have any idea about how to connect to a sql server from oracle database using db link to syncronize the data? I need to pull the data from Sql server table to Oracle tables and relay messages back to the sql server.
Thank you,
Praveen.

we have 2 products - DG4MSQL and DG4ODBC.
DG4ODBC is for free and requires a 3rd party ODBC driver and it can connect to any 3rd party database as long as you use a suitable ODBC driver
DG4MSQL is more powerfull as it is designed for MS SQL Server databases and it supports many functions it can directly map to SQL Server equivalents - it can also call remote procedures or participtae in distributed transactions. Please be aware DG4MSQL requires a license - it is not for free.
Check out Metalink and you'll find notes how to configure both products.

Failure when connecting MS SQL SERVER from ODI ! could not load JDBS driver

i have some trouble with connecting MS SQL SERVER from ODI.
I have already downland jdbs driver 3.0 (and 2.0 ) and copy the sqljdbc4.jar to D:\oracle\product\11.1.1\Oracle_ODI_1\oracledi\agent\drivers( where the oracle jdbs driver is already exitst )....but i have this error :
could not load JDBS driver class..
thanks

After more investigation and even more chocolate, we've identified the problem and it's now working. For anyone else who strikes this problem in future, here's something to check/consider/try:
Even though Squirrel SQL Client was connecting and working ok using the MS JDBC driver (v 3.0), it recorded this in its logs:
Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "Latin1_General_CI_AS" in the INTERSECT operation.
We've found that the open source jTDS driver does not have the same issue as the Microsoft one.
We've installed the current jTDS driver, recorded the driver name (net.sourceforge.jtds.jdbc.Driver) and the JDBC URL (jdbc:jtds:sqlserver://<hostname>:1433/<database>) and the connection is now working fine.
Hope this helps other people...
Thanks to those of you who offered suggestions and things to check...much appreciated.

DSNless connection to SQL Server and Oracle

hi,
how can i connect to SQl Server and Oracle without specifying the DSN.
zulfgi

My favorite reply again:
Someone wrote in a newsgroup about configuring some kind of "temporary DSN".
His example was for Excel, but it will maybe work the same way for other drivers:
db = DriverManager.getConnection(
"jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};DBQ=c:/temp/test2.xls;DriverID=22;READONLY=false","","");
Also someone else suggested for SQLServer:
db = DriverManager.getConnection("jdbc:odbc:Driver={SQL Server};Server=MyServerName;Database=MyDataBase","","");
Find out the right driver clause for Oracle; look at the names the control panel ODBC manager shows.
Regards,
Hartmut

Connect Sql Server From Oracle Both on Windows

I want to connect my SQL Server running on Windows2003 with my oracle database 10g which is also on windows through some odbc which i have also created on my machine running oracle 10g. Can some one guide me with simple steps.

Generally most folks use OLEDB rather than ODBC for that.

Connecting to SQL Server from Solaris using Perl & Oracle.

Hey All,
Using the DBI.pm provided by the default Perl package that comes integrated with Oracle server, I am being able to connect to the Oracle database through Perl.
But is there a way I can connect to SQL Server through Perl using any package provided by Oracle like ODBC or something else (on Solaris)
I am using following version of Oracle server on Solaris 10
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production
TIA
Parag

The problem is I cannot install any third party package but I found something. Have a look at this:
bash-3.00$ pwd
/opt/oracle/product/10.2.0.4.0/perl/lib/site_perl/5.8.3/sun4-solaris-thread-multi/Win32
bash-3.00$ ls -l
total 10
-rwxr-xr-x 1 oracle dba 4532 Jul 7 2004 DBIODBC.pm
bash-3.00$
Will explore more and keep you all posted.
Cheers,
Parag

Connect to sql server from 10g webforms using exec sql

Hi
We are embarking on a project to upgrade our 6i client server forms to 10g web
based. One of our forms uses the exec_sql package to open a connection to an MS
SQL Server database and execute queries on that database.
Oracle open client adapter and an odbc driver for SQL Server is installed on
every client to achieve this. I have read that open client adapter is no longer
available on 10g.
I also read that there a feature of the Oracle database called Generic
Connectivity which would allow us to install an odbc driver on the database
server and allow us to connect to sql server. However I discovered that this
feature is not supported on TRU64 - the operating system our database runs on.
I have read about Oracle Transparent gateways but I have been informed that they are not supported from forms.
Is there any alternative? How can our webform connect to sql server and execute
queries against it? The sql we need to execute is already sql server compliant so no translation is required - just a simple pass through
thanks
paul schweiger

I used in the past Forms 6i against DB2 on a mainframe through Transparent Gateway for DB2. So I'm wondering who did you tell such a configuration does not work. And the migration guide states:
/* Open Client Adapters (OCA)
In order to provide platform-independent access to a wider range of non-Oracle data sources, use the Oracle Transparent Gateway and Generic Connectivity solutions in place of OCA. */
At least gateway is mentioned.

Accessing SQL Server from Oracle

I found an article:
http:www.databasejournal.com/features/oracle/article.php/3442661
It shows how to setup a connection from Oracle to SQL Server.
I am new to Oracle Using SQL Loader and PL/SQL.
I would like to use the SQL Loader in Oracle to load a table in SQL Server. It is my understanding that a ctl file is used and is called by an Oracle application.
I would not have an Oracle application. I would like to use the ctl file to load the SQL Server table. Can someone point me on how to use the ctl file for SQL Server?
Also, in PL/SQL would there be a connection string to connect to SQL Server when accessing a table.
Is there a book or some documentation that would address the above?
Thanks in Advance.

that article shows you how to access SQL Server database through Oracle, therefore you have no need to use SQL Loader to load data from SQL Server bcos it can be queried directly by using simple select statement.
If you want to load the data into Oracle just use CREATE TABLE ... AS SELECT ...
in PL/SQL, what you need is the database link.
Cheers,

Problem connecting to SQL Server from JDeveloper 10g using jdbc third party

I am using Oracle 10g Jdeveloper and I tried to setup a database
connection to SQL Server using various Drivers for JDBC as Merlin, jtds, inet.tds, etc.
(I had no problem to set up a connection to an Oracle Database using the
Oracle JDBC driver).
When I am testing the connection throughout the wizard, I do receive
this error message: "Unable to find driver:
com.microsoft.jdbc.sqlserver.SQLServerDriver".
I m not understanding from last 3 days where to place the corresponding JAR files so thaI may not get the Error.
When I hit n trialed at various directories of the JDeveloper as </rootDir/jdbc/lib>
</rootDir/lib>
</root/jdev/my Work/Application1/Project1/public_html>
</root/jdev/my Work/Application1/Project1/public_html/web-inf/>
when I tested the connection I do received:
"Unable to find driver:
xxx.xxx.xxx.xxxxxxx Unable to find driver:
Obviously it can't locate the Micrososft JDBC driver but I can't
figure out why.
I tried all kind of things without any success. Is somebody can help
me and took me beyond this.
I m trying to build DataSource connection from JavaBeans.
Please make me out of this cave. I m not finding any of the way to do this.
The last code I tried is
try {
Class.forName("com.inet.pool.PoolDriver");
com.inet.tds.TdsDataSource tds = new com.inet.tds.TdsDataSource();
tds.setServerName( "local" );
tds.setDatabaseName( "bluff" );
tds.setUser( dbUserName );
tds.setPassword( dbPassword );
DataSource ds = tds;
Connection con = ds.getConnection(dbUserName,dbPassword);
Statement stmt;
ResultSet rs = null;
Thanks,

you are confusing me at least as your error is discussing the microsoft driver yet you are configuring the inet datasource.
I do not use JDeveloper, but you need to make sure that whatever is servicing your web app/JavaBean has access to the driver. Not sure why you are not doing a JNDI look up of the resoure, but because you are not you can stick the driver jar in the lib directory within the WAR bundle. I would suggest that you add the driver to the lib/ext or the lib directory which is loaded at boot time for your web container and then use JNDI to look up your DataSource to reduce your coding maintenance headaches.

Query in sql server from Oracle 9.2

Hi
How can I to connect and execute query from Oracle without to use others products ( DG4MSQL ....etc) ?
using 9.2.08

Hi,
I say it is 'free' because Dg4ODBC is included in your RDBMS license and you just need to supply a third party ODBC driver.
See this note -
Gateway and Generic Connectivity Licensing Considerations (Doc ID 232482.1)
You need to install and configure it in an ORACLE_HOME on a machine somewhere then you can use database links from to connect to it and select from non-Oracle databases.
Have a look at these notes depending on the platfrom you plan to use -

As I said in my earlier update if SQL*Server is your non-Oracle database then an standalone install on Windows is the best option to be able to use the Microsoft ODBC driver, although there is now a MS ODBC available on Linux x86-64 bit.
Please read through the notes I have referred to because they should have the information you need.
