How to create database link between oracle and SQL Server

Hello Everyone,
Here i have Oracle Database 9i and SQL Server 2005 databases.
I have some tables in sql server db and i want to access from Oracle.
How to create a database link between these two servers
Thanks,

Thanks for Everyone,
I was struggle with this almost 10 days....
I created Database link from Oracle to SQL Server
Now it is fine.........
Here i am giving my servers configuration and proceedure how i created the db link...@
Using Generic Connectivity (HSODBC) we can create db link between Oracle and SQL server.
Machine (1)
DB Version : Oracle 9.2.0.7.0
Operating System : HP-UX Itanuim 64 11.23
IP : 192.168.0.31
Host : abcdbt
Machine (2)
Version : SQL Server 2005
Operating System : Windows server 2003 x86
IP : 192.168.0.175
Host : SQLDEV1
User/PW : sa/abc@123! (Connect to database)
Database : SQLTEST (exsisting)
Table : T (“ T “ is the table existing in SQLTEST database with 10 rows)
Prerequisites in Machine (2):
a) Oracle 10g software
b) User account to access SQL Server database (sa/abc@123!)
c) Existing SQL Server Database (SQLTEST)
d) Tables (testing purpose) (T)
Steps:
1) Install Oracle 10.2.0.1 (Only SW,No need of database) *(Machine 2)*
2) Create a DSN where your windows Oracle 10g SW resides *(Machine 2)*
Control panel >> Administrative Tools >> Data Source (ODBC) >> System DSN ADD
You can follow this link also.....
http://www.databasejournal.com/features/oracle/article.php/3442661/Making-a-Connection-from-Oracle-to-SQL-Server.htm
I created DSN as
DSN name : SQLTEST
User : SA/abc@123! (Existing user account)
Host : 192.168.0.175 (machine 2)
Already I have 1 database in SQL Server with the name SQLTEST
You can create DSN with different name also (not same as db name also)
3) Create a hsodbc init file in $ORACLE_HOME\hs\admin *(Machine 2)*
Create init<DSN NAME> file
Ex: initSQLTEST
Copy inithsodbc to initSQLTEST
And edit
initSQLTEST file
HS_FDS_CONNECT_INFO = SQLTEST <DSN NAME>*
HS_FDS_TRACE_LEVEL = OFF*
save the file....@
4) Configure Listener.ora *(Machine 2)*
LISTENER_NEW =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
SID_LIST_LISTENER_NEW =
(SID_LIST =
(SID_DESC =
(SID_NAME = SQLTEST) *+< Here SQLTEST is DSN NAME >+*
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = hsodbc))
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = extproc) )
:> lsnrctl start LISTENER_NEW
5) Configure tnsname.ora *(Machine 2)*
SQLTEST11 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.175)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = SQLTEST))
(HS=OK)
:> tnsping SQLTEST11
If No errors then conti….
6) Configure a file *(Machine 1)*
Cd $TNS_ADMIN ($ORACLE_HOME/network/admin)
Create a file
$ vi TEST_abcdbt_ifile.ora
something=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST =192.168.0.175) (PORT=1525))
(CONNECT_DATA=
(SID=SQLTEST))
(HS=OK)
$ tnsping something
$ sqlplus system/manager
Your connected to Oracle database *(machine 1)*
create database link xyz connect to “sa” identified by “abc@123!” using ‘SOMETHING’;
select * from t@xyz;10 rows selected.
Thanks,

Creating Database Link from Oracle to SQL Server

I am trying to create a database link from Oracle to SQL Server, and the documentation is about as clear as mud to me. Can anyone send me clear instructions on exactly what I need to do? What needs to be in tnsnames.ora and listener.ora files? Is there anything other than those two files that needs to be set up? Do I set up an ODBC connection? Anything else? I want to execute queries against a SQL Server database and load data into Oracle database.
Thanks so much,
Susan

These are the instructions from an old document I created. The steps are same for SQL Server and Sybase. Hope it helps.
The 9i Transparent Gateway Software is in Oracle Software CD -> oracle9i database -> Custom -> Oracle Transparent Gateways
The gateway can be installed on the same machine as the Oracle database or
on the Sybase server or on a third machine as a stand-alone.
We have installed the gateway software in one of oracle database
servers in a separate oracle home.
These are the steps involved in configuring a gateway to a Sybase database
1. Install Sybase client and Gateway software on the Gateway Server
2. Configure <initsidfile> in the Gateway Server's <gatewayhome>
 /u00/app/oracle/product/9.2.0/tg4sybs/admin/init<gatewaysid>.ora
Sybase server and database information is required for this step.
eg: HS_FDS_CONNECT_INFO=USTRUD01.uwd
3. Add an entry in listener.ora in <listnenerhome>
 (/u00/app/oracle/product/9.0.1/network/admin/listener.ora) for the <gatewaysid>
4. Edit the tnsnames file (/u00/app/oracle/product/9.0.1/network/admin/tnsnames.ora)
to add an entry <tnsalias> for the <gatewaysid>
5. Create a database link to the Sybase database in the oracle database.
The steps for creating the database link are
a. create a login oracle_tgw in the sybase server
b. add the user to the sybase database with the necessary privilege on the tables
c. create the database link in the required oracle database using the command
 "create public database link <dblinkname> connect to oracle_tgw identified by password using 'tnsalias'; "
6. Restart the gateway listener.

Creation of database link from oracle to sql server 2000

Hi
I need to create a database link from oracle to sql server 2000.

Assuming your Oracle database is running on Windows, you can set up a database link using ODBC using Heterogeneous Services and Generic Connectivity, but there are some functional limitations (i.e. no two-phase commits). If you can live with those limitations but aren't on Windows, you can generally purchase an ODBC driver for your operating system that will connect to SQL Server through someone like DataDirect and still use Generic Connectivity. If you cannot live with those limitations, you can purchase one of Oracle's Transparent Gateway products (though this can get somewhat pricey).
What version of Oracle are you on?
What operating system(s) are you using?
What are you going to use the database link for?

Creating Database link from Oracle9i to SQL server 2000

Pls how do I create connectivity from Oracle9i database to query a table in an SQL server 2000 database.
Pls I need the necessary steps to take.
Thanx

There are 2 solutions that you can use:
1) Transparent Gateway for SQL Server
2) Generic Connectivity
Generic Connectivity is free with the database but has less features than the Gateway. For Generic Connectivity you will need to obtain an ODBC driver.
The steps for using the gateway are available in the gateway manual and the steps for using Generic Connectivity is available in Chap 7 of the Heterogeneous Connectivity Administrator's Guide.

Oracle DB Link from Oracle to SQL Server

Dear buddies,
I am trying to create a dblink from Oracle to SQL Server.
This is my tnsnames.ora
sq =
(DESCRIPTION=
 (ADDRESS=(PROTOCOL=tcp)(HOST=LOCALHOST)(PORT=1521)
 (CONNECT_DATA=(SID=sq))
 (HS=OK)
)This is my listener
SID_LIST_LISTENER =
(SID_LIST =
 (SID_DESC =
 (SID_NAME = sq)
 (ORACLE_HOME = D:\oracle\product\10.2.0\db_2)
 (PROGRAM = hsodbc)
LISTENER =
(DESCRIPTION =
 (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)initsq.ora
# This is a sample agent init file that contains the HS parameters that are
# needed for an ODBC Agent.
# HS init parameters
HS_FDS_CONNECT_INFO = sq
HS_FDS_TRACE_LEVEL = OFF
# Environment variables required for the non-Oracle system
#set <envvar>=<value>I have created my System DSN for sq with the appropriate values which works fine when I tested the connection.
These 2 databases are in different servers.
This is how I created the db link in Oracle
create public database link sq
CONNECT TO XXX IDENTIFIED BY "XXX"
using 'sq'
select "Column1"
from "Table1"@'sq';The error I receive is: ORA-01729: database link name expected
When I try to recreate the database link it tells me that: ORA-02011: duplicate database link name
I hope someone could guide me.
Thanks.

DB Link from Oracle to SQL Server error

Dear buddies,
I need to perfome some select on the tables which reside in SQL Server 2005 from Oracle 10g.
I followed the steps given in :
http://www.dba-oracle.com/t_heterogeneous_database_connections_sql_server.htm
I could perform a TNS ping which is successful but only when I perform a select I receive this error.
ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Unable to retrieve text of NETWORK/NCR message 65535
ORA-02063: preceding 2 lines from SQLS
I have checked that my dsn name is in small caps all the way wherever it is used(Since its suggested in many sites).
Please guide me.
I am really looking ahead for a solution.

How to create a DBlink from oracle database on unix to sqlserver

To create a database link from oracle to sqlserver with NT authentication

Hi ,
I need to create a database link from oracle 9i to sql server database with windows authentication.I dont have the database username and password instead the access is given to my NT ID and password.So can anyone provide me the information about creating a dblink to sql server with windows authentication.
Thanks

Oracle is attempting to log in to SQL Server using NT authentication.
The Oracle process, however, is running presumably with a local admin account (normal for a Windows service). SQL Server has no idea what this local account is, so it denies the login.
You could change the Oracle service to run as a known user (presumably not as your Windows ID but some other Windows ID you create explicitly for Oracle) and then grant that Windows ID in SQL Server appropriate privileges. That would mean, though, that when you queried tables over the database link, you'd be using that new Windows ID's privileges on SQL Server, not your Windows ID's privileges.
As I've said, though, this is a general architectural limitation for a multi-tier architecture. The end system (SQL Server) generally has no idea who the end user (your Windows ID) is when that user is coming through a middle tier (Oracle). So it cannot apply end-user permissions to connections created by the middle tier.

Problem with using database link from oracle 7 to oracle 9i

Hi To Every One
I have two oracle database oracle 7.3.4.0.1 and oracle 9i 9.2.0.1.0.
and the tns alias to connect to oracle 9i database is oracle9i and tns
alias to oracle 7 database is oracle7.I have no problem in connect to
these database using these tns aliases from either database.The tns
alias for oracle 7 is available in tnsnames.ora file of oracle9i and
tns alias for oracle 9i is available in tnsnames.ora file of oracle 7.
So there is no connection problem from each other.Connection is
working fine for each other but the problem with database links is
like this
Problem:
when i create database link from oracle9i user or public database link
from oracle9i for oracle7 user like this
SQL ORACLE9I >CREATE DATABASE LINK ORACLE7 CONNECT TO <ORACLE7USER>
IDENTIFIED BY <PASSWORD> USING 'ORACLE7';
OR
SQL ORACLE9I >CREATE PUBLIC DATABASE LINK ORACLE7 CONNECT TO <ORACLE7USER>
IDENTIFIED BY <PASSWORD> USING 'ORACLE7';
The links get created sucessfully but when i write command like
SQL ORACLE9I> DESC <ORACLE7USER_NAME>.<ORACLE7USER_TABLENAME>@ORACLE7
I RECEIVE A ORACLE ERROR LIKE
ORA-12663 SERVICE REQUIRED BY CLIENT IS NOT AVAILABLE ON THE SERVER.
OR IF MY COMMAND IS LIKE
SQL ORACLE9I> SELECT <FEILD_NAME> FROM
<ORACLE7USER_NAME>.<ORACLE7USER_TABLENAME>@ORACLE7;
I RECEIVE AN ORACLE ERROR LIKE
ORA-01002 FETCH OUT OF SEQUENCE.
ORA-02063: preceding line from ORACLE7
BUT IF I CREATE A LINK FROM ORACLE7 USER FOR ORACLE9I USER
IT WORKS FINE.
PLZ HELP ME WHAT IS THE PROBLEM THAT THE LINK FOR ORACLE 7 IS NOT WORKING WHEN
IT IS BEING CREATED FROM ORACLE9I.
Thank u.

Oracle 9.2.0 does not support connectivity to Oracle 7. The newest version that will support this is 9.0.1.
