Oracle connectivity to SQL Server

I read that Oracle recommends the gateway be installed on the SQL server box for optimal performance. However, if Im running a SQL Server cluster on Wind 2000 server, in an active/passive mode, what is the recommended installation architecture? Should I install it on a third machine, configured to access the active node of the cluster or can/should it be installed on both nodes, but only having the active db node running the active gateway node?
Thanks

Hi,
You have 2 major options:
1. Use Generic Connectivity with your Oracle 9i database running on Solaris. However it requires a proper ODBC-Driver to be installed on Solaris capable of connecting to Microsoft SQL Server
MetaLink DocID: 245549.1 - How to setup Generic Connectivity - HSODBC - on SUN Solaris
Remark: Oracle 9i has been de-supported, should you run into new bugs they wouldn't be fixed by Oracle
2. Install and use the Database Gateway for ODBC 11g on the same machine which hosts the SQL Server database. Usage of this gateway is included in the Oracle database license. DG4ODBC also requires an ODBC-Driver but this one is mostly already present.
Another option would be to install the Database Gateway for MS SQL Server (DG4MSQL) 11g on the same machine which hosts the SQL Server database. However this gateway requires an additional license. The big advantage of this gateway over DG4ODBC is that it supports the two phase commit protocol (distributed updates) and calling of SQL Server stored procedures. Also the dataype mapping is better compared to DG4ODBC.
One thing though; in order for you Oracle 9i database to cooperate with one of the 11g gateways a patch for bug 5965763 on top of 9.2.0.8.0 is required. See also MetaLink DocID: 457808.1 for more details.
I hope this get you going.

Ed

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:

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

Oracle XE connection to SQL Server 2000

Hello everybody,
I need to make a connection to a table in SQL Server 2000. I am using Oracle XE with Apex 3.0.1.
SQL and XE are on the same server(windows server 2003).
I need to make an application that uses some data of the SQL Server and for the rest it uses data from Oracle XE.
How can I make this connection to SQL Server from Oracle XE? Some suggestion where I should start, would be great.
It would be great if the Apex developers would not notice that the data is retrieved from SQL Server, is this possible?
For 10g there is a gateway for this I believe, but not for XE.
Thank you for your time!

Thanks, after searching some information about Heterogeneous Services.

Connecting Oracle(64bit) to SQL Server(32bit) with heterogeneous serv ODBC

Hi,
We are planing the migration of 32bit Oracle 9.2.0.8 (MS Windows Server 2003 EE SP1) to 64 bit Oracle 10.2.0.4 (MS Windows Server 2003 Standard x64 Edition SP2).
We have tested the migration using export/import procedure, and everything passed ok.
The problem is because the database we are planning to migrate (32bit) using Oracles heterogeneous Services ODBC agent in connection to 32 bit SQL Server 2000. When we have tried to implement that on 64bit 10.2.0.4 oracle we always get the message:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
Then we looked up the metalink and find the document: Is Generic Connectivity Available On Linux Or Windows 64-bit Platforms ? [*ID 361676.1*]
Is there any way to make the connection between 64bit Oracle 10.2.0.4 and 32bit SQL Server using system DSN within the Windows ODBC Data Sources with choosing the SQL Server driver?
The option with Database Gateway for ODBC (DG4ODBC) isn't free.
Thanks

Hi everyone
As far as I am aware, you need to install the Discoverer EUL into an Oracle database and then use an ODBC connection to SQL Server. This is because Discoverer has hooks into the Oracle database and is looking for features that only exist in an Oracle database. If you are using an Infrastructure, which is mandatory when using 4i, you can use that database to store your EUL using an ODBC connection over to SQL Server.
I hope this helps
Best wishes

Oracle 9i to SQL Server 2000 Connectivity

Oracle database to Sql server connection

Hi,
Can anyone please suggest any documents to create db link from oracle to sql server.
Thanks and Regards
Phani

You can use Oracles heterogeneous Services ODBC agent to connect to SQL Server, if your Oracle database is running in windows then very easy to do the ODBC connection
control pannel-->ODBC icon -->System DSN tab and then click the Add button.
After this add the connectivity details in $ORACLE_HOME/hs/admin/initMYSQLSERVERDSN.ora file
If your Oracle database is running on Linux then you need to install something called FreeTDS driver can be downloaded from http://ibiblio.org/pub/Linux/ALPHA/freetds/freetds-0.60.tgz ; to define ODBC connection and then add the details into $ORACLE_HOME/hs/admin/initMYSQLSERVERDSN.ora file
Thanks

Steps to change universe database connection from SQL server to Oracle 10

Hi,
we are moving from sql server to Oracle 10.Please let me know the steps and various parameters I should consider while changing universe database connection from SQL server to Oracle 10.
Following are the steps which I assumed :
1.     create a new Oracle database connection or edit the existing connection to point to Oracle server
2.     Need to check sql for each object, having integrity check for universe will solve the purpose of parsing each object
3.     Exporting the universe after integrity check
4.     Report data testing
Let me know if I miss on any steps.Also what all factors I need to consider while moving to Oracle for eg: what @ custom sql,what @ table names,what @ LOV etc.
Kindly reply

Thanks Abhijeet and Shreyash,
I will follow the steps you have suggested.
Actually I was searching for this on net and got to know that with Oracle database connection,theres lot of stuff needs to take care of in terms of custom sql and LOV and in our case,we have lot of custom sql for each object in the universe so just wanted to confirm.
I will do the changes and let you guys know in case theres any isuue specifically to Oracle.

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

ODBC connection between SQL Server,Oracle Failure

Dears,,
I have Oracle database and SQL Server on another server.

Oracle 10g connectivity with sql server 2000 through oracle transpa gateway

dear gurus.
i am to connecto oracle 10g with sql server 2000 through oracle transparent gateway.
i have installed transparent gateway and proper configured. also link is created.
but when i execute query "select * from city@inventory" , so an error displayed.
ORA-12500: TNS:listener failed to start a dedicated server process.
kindly suggest me what could be the cause.
regards,

if the listener fails to spawn a dedicated server process it is commonly indicating an issue with the listener. So posting the listener and also a listener trace including a description of the env where you installed the gateway into which directory would be helpfull. Please keep also in mind if you have for example a 10.2.0.3 database and you install into this directoty a 10.2.0.1 gateway you have to reapply the patchset again do get consistent file version.
So please describe more detailed your env.
