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_NAME = PLSExtProc)
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)

(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=

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.

OWB 10g -- Can't Create Database Links for Data Source and Target

We installed OWB 10g server components on a Unix box running Oracle 10g (R2) database. The Designer Repository is in one instance. The Runtime Repository and the Target are in another instance. The OWB client component was installed on Windows XP. We create a data source module and a target module in OWB. The data source is on another Unix box running Oracle 9i (R2) database. We try to create database links for data source module and target module, respective. But when we created and tested the DB links, the DB links were failed.
For the database link of data source, we got the following error message:
Testing...
Failed.
SQL Exception
Repository Error:SQL Exception..
Class Name: CacheMediator.
Method Name: getDDEntryFromDB.
Repository Error Message: ORA-12170: TNS:Connect timeout occurred
For the database link of target , we got the following error message:
Testing...
Failed.
API2215: Cannot create database link. Please contact Oracle Support with the stack trace and the details on how to reproduce it.
Repository Error:SQL Exception..
Class Name: oracle.wh.ui.integrator.common.RepositoryUtils.
Method Name: createDBLink(String, String, String, String).
Method Name: -1.
Repository Error Message: java.sql.SQLException: ORA-00933: SQL command not properly ended.
However, we could connect to the two databases (data source and target) using the OWBs utility SQL Plus.
Please help us to solve this problem. Thank you.

As I said prior the database link creation should work from within the OWB client (also in 10).
Regarding your issue when deploying, have you registered your target locations in the deployment manager and did you first deployed your target location's connector which points out to your source?
I myself had some problems with database link creations in the past and I can't remember exactly what they were but it had something to do with
- the use of abnormal characters in the database link name
- long domain name used in as names.default_domain in my sqlnet.ora file
What you can do is check the actual script created when deploying the database link so see if there's something strange and check if executing the created script manually works or not.

Can't create database link when password has special character

I'm trying to execute the following statement within sqlplus
create database link alpha connect to scott identified by tiger! using 'db_alpha'
note that the password for the account has an exclamation point in it. the command fails. I've tried placing the password in quotes (') and double-quotes ("). The double-quotes work, but then the link fails to function properly.
We are required to have a special character in our passwords... so how do I get that special character into the password for the database link?
Thanks in advance,
Darren

for some weird reason, I can't post the reply I want. every time I try, the forum hangs and doesn't save the message. give me a sec...
I have put the password within double quotes... so I'm starting to think the problem is something else. I've been reading other posts regarding creating database links and I've obtained limited results. Here's what I've done, and the results I'm getting.
(names changed to protect the innocent)
My oracle database is on SYSA. I'm on SYSB. I set my TWO_TASK=SYSA and just use sqlplus to connect as user1.
I want to run a command on user2's tables. Normally I would just grant read access to user1 on user2's tables and use a command like
nert spaces to get this to save (weird forum bug here, I can't delete the text to the left)
SQL> sel{color:black}{color}ect * fr{color:black}{color}om u{color:black}{color}s{color:black}{color}e{color:black}{color}r{color:black}{color}2{color:black}{color}.{color:black}{color}m{color:black}{color}y{color:black}{color}_{color:black}{color}t{color:black}{color}a{color:black}{color}b{color:black}{color}l{color:black}{color}e{color:black}{color};
However, user2 is for test data and those tables get dropped and recreated often and it is cumbersome to try to remind everyone to recreate the grants. So I can't trust that user1 will have access to user2's tables. So my goal with the database link is to create a private (for user1 only) database link and access the tables that way, that way I bypass the grant issue. This works out better for me because we only change that password every 2 months. I just recreate the database link once every two months, rather than recreate grants multiple times every week. Well, that's the theory anyway.
Back to creating the database link, I thought my issue was the special character in the password because if I remove the exclamation point everyting works (except that the password is invalid). Below is what it looks like when I do this...
Attempt #1:
SQL> create database link BLAH connect to user2 identified by "tiger" using 'BLAH';
Database link created
SQL> sel{color:black}{color}ect * fr{color:black}{color}om my{color:black}{color}_{color:black}{color}table{color:black}{color}@{color:black}{color}BLAH;
sel{color:black}{color}ect * fr{color:black}{color}om my{color:black}{color}_{color:black}{color}ta{color:black}{color}ble{color:black}{color}@{color:black}{color}BLAH
ERROR at line 1:
ORA-01017: invalid username/password; logon denied
ORA-02063: preceding line from BLAH
So that looks like it's just a password issue. If I put in the correct password... the error changes to this...
Attempt #2:
SQL> create database link BLAH connect to user2 identified by "tiger!" using 'BLAH';
Database link created
SQL> sel{color:black}{color}ect {color:black}{color}* fr{color:black}{color}om my{color:black}{color}_{color:black}{color}table{color:black}{color}@BLAH;
sel{color:black}{color}ect * fr{color:black}{color}om my{color:black}{color}_ta{color:black}{color}ble{color:black}{color}@BLAH
ERROR at line 1:
ORA-02085: database link BLAH.AAA.BB.CCC.DDD connects to
DEVDB.AAA.BB.CCC.DDD
To me, that doesn't make sense. If the link isn't working... how did it get the "invalid username/password" in Attempt #1?
Anyway, in perusing other forum posts, one post said to put in the full text from the tnsnames.ora file instead of the alias. So I do a little cut/paste and try this...
Attempt #3:
SQL> create database link BLAH connect to user2 identified by "tiger!" using
2 '(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = server001.aaa.bb.ccc.ddd)(PORT = 9999)))
3 (CONNECT_DATA = (SERVICE_NAME = devdb)))';
Database link created.
SQL> sel{color:black}{color}ect {color:black}{color}* fro{color:black}{color}m my{color:black}{color}_{color:black}{color}tab{color:black}{color}le{color:black}{color}@BLAH;
sel{color:black}{color}ect {color:black}{color}* fr{color:black}{color}om {color:black}{color}my_{color:black}{color}tab{color:black}{color}le@B{color:black}{color}LAH
ERROR at line 1:
ORA-02085: database link BLAH.AAA.BB.CCC.DDD connects to
DEVDB.AAA.BB.CCC.DDD
Any ideas on what I'm doing wrong?

OWB can not create database link

Hello!
We use OWB 10.1. We are unable to create database link in the owb as a source for metadata information. The database user we use to connect to the owb have got the right to create database links and the same user can create database links outside the owb. we get the error message
Testing...
Failed.
API2215: Cannot create database link. Please contact Oracle Support with the stack trace and the details on how to reproduce it.
the database user is not the owner of the repository. if we use the repository owner to create the database link it works.
it is also impossible to use a database link, that is created outside the owb, if we use an user that is not the repository owner.
the error message is:
java.sql.SQLException: ORA-02019: connection description for remote database not found
at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:158) ....
with the owner everything works fine.

hi,
If public dblink is a problem then u can create the table with PUBLIC SYNONYM and create a synonym of the table in ur DB so that u can access the table in ur DB and still make I/U/D in the table in the other DB. We just have to grant previlege for the synonym created for DML statements.

I trying to create database link from Oracle 11g to MS Sql and I'm not succesful.
I found tutorial for Oracle 10g, but it does't work.
I created odbc data source, then I modified tnsnames.ora and listener.ora, then I created initkw.ora in HS directory and then I created dabase link, but it does't work.
Can you help me please? Thanks for help ... ondra

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.

Can we create new tablespace in Oracle Database 10g Express Edition?

Hi,
Can we create new tablespace in Oracle Database 10g Express Edition instead of using the default "users" tablespace provided?
Please advise.
Thank you.

Correct. The sum of all user tablespaces is not allowed to exceed 4 GIG.
You could try shrinking your tablespaces. Theres a script called maxshrink on http://asktom.oracle.com which is useful for this.
You could compress your tables.
If you are storing lobs, you could consider storing them as bfiles.
Or upgrade to Oracle Standard Edition 1. Its not that expensive.

its urgent.....
thanks in advance

Hi,
You need create database link to schema that is assigned to your workspace (application parsing schema)
Schema need have CREATE DATABASE LINK system privilege.
