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
Best regards.

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.

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:

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

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.

Hartmut

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.

BPC 7.0 Install error - Cannot connect to SQL server

Hi,
I am in the process of installing BPC 7.0 and encountered the following error after filling the "Advanced settings" details on the server info screen:
*Cannot connect SQL server.
Please check the SQL server connection or check System Admin ID to access the sql server.*
I know that the System Admin ID I provided in the previous (service type accounts) screen is correct. What am I missings? Appreciate the help asap!

BPC installation user has to be SysAdmin into SQl Server.
Also make sure that SQL Server was installed having Windows authentication enable otherwise the connection to SQL Server can not be establish.
Into Application Server (the server where you are trying to install BPC) open Management Studio and see if you can connect to SQL Server.
Are you using special ports or instances fro SQL Server?
Please make sure you are providing all these information into BPC setup.

Critical Error: Cannot Connect to SQL Server. {SQL Server} not found. Timeout expired.

Greetings,
I have been having some issues with various areas in a SharePoint 2013 farm. While working my way through a bazillion errors in the event logs, I have found the following error. It looks to be happening every hour; almost exactly 5 minutes after
every hour.
"Cannot connect to SQL Server. A_PROD_SP01 not found. Additional error information from SQL Server is included below.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."
I also find, a health analyzer rule that is failing at the same time:
Availability: One or more servers is not responding.
However, there isn't any server listed in the Failing Servers section.
Any thoughts?
Thank you,
Bob

Hi Bob,
For your issue, it can be caused by that the SharePoint database access account might not have the necessary permissions to communicate with the SQL Server. Please grant correct permissions to the database access account:
You must be a member of the Farm Administrators group to perform this task.
Assign the database access account:
On the Central Administration home page, click Security and in the
General Security section click Configure service accounts.
On the Service Accounts page, in the Credential Management section, in the upper drop-down list click the correct Web application pool for your Web application.
In the Select an account for this component drop-down list, click the domain account that you want to associate with this Web application pool, or click
Register new managed account to associate a new domain account with this application pool.
Click OK to save changes.

If this does not work, then Oracle HSO will also not work.
Once you have confirmed that this is working, then configure the HSO service for Oracle.
If that fails, enables ODBC client tracing for that HSO service (in the init file for that service) to see exactly what ODBC calls Oracle is making and which of these are failing.

-net.sourceforge.jtds.jdbc.Driver ERROR WHILE CONNECTING TO SQL SERVER

Hi,
While making a new connection to Sql Server Express Edition Database, through Oracle Sql Developer i am getting a problem when retrieving the database.The error is "-net.sourceforge.jtds.jdbc.Driver" .I have downloaded the "jTDS - SQL Server and Sybase JDBC driver " from sourceforge website, but i am confused about where to paste it.
thanks.

I'm not sure why you are having the error but I am sure of the following:
1. This forum is not appropriate for SQL*Developer questions.
2. Or questions about code from SourceForge
3. Or Microsoft products.
It seems unlikely this has anything to do with Oracle so I would recommend you find a forum related to the driver if one exists. Otherwise you can try the SQL*Developer forum but I would be there aren't more than a dozen other people on the product trying to do this.

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.
