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.

Database link from Oracle to MySQL with the use of unixODBC

Hi,
I have 2 servers.
Server A:
- CentOS_5.1 x386
- MySQL 5.1
- unixODBC
- mysql-connector-odbc
Server B:
- CentOS_5.1 x86_64
- Oracle 11g
- unixODBC
- mysql-connector-odbc
I've configured ODBC, so I am able to do "isql <DSN> oracle oracle -v" sucessfully with "root" and "oracle" user on Oracle server. I've configured listener.ora and tnsnames.ora
I added below lines to listener.ora
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=mysqlware)
(ORACLE_HOME=/u01/app/oracle/product/11.1.0/db_1)
(PROGRAM=dg4odbc)
(ENVS=LD_LIBRARY_PATH=/u01/app/oracle/product/11.1.0/db_1/hs/lib:/usr/lib64/:$ORACLE_HOME/lib)
and lines below to tnsnames.ora
mysqlware=
(DESCRIPTION=

There is "emp" table in MySQL, from where I can even select with the use of isql command and from this Oracle server.
I would really appreciate some help here.
Thanks in advance.

Database link from Oracle to MySQL

I tried and googled an tried again...but I can't get this to work. So if you can spare a moment, please help me out (or try to ;-) ).
Environment:
The Oracle Developer Days Virtual Box image, so that's 11gR2 EE on OEL. MySQL 5.1.51-community + mysql-connector-odbc-5.1.7-0.i386.rpm
1. Created a database called test in MySQL, with a user "oracle" and a password "123".
2. Created the file /home/oracle/.odbc.ini with as contents:
[ODBC Data Sources]
myodbc5 = MySQL ODBC 5.1.7 Driver DSN

DRIVER      = /usr/lib/libmyodbc5.so

USER        = oracle
PASSWORD    = 123
DATABASE    = test
CHARSET     = latin13. Created the file /home/oracle/app/oracle/product/11.2.0/dbhome_1/hs/admin/initmyodbc5.ora

       (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA = (SID=myodbc5))

      (PROGRAM = dg4odbc)
      (ENVS ="LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/hs/lib:/usr/lib:/lib")
)6. Ran some tests:
a. isql dg4odbc -> Connected!
b. tnsping dg4odbc -> OK
c. lsnrctl status -> Service "myodbc5" has 1 instance(s). Instance "myodbc5", status UNKNOWN, has 1 handler(s) for this service...
d. in SQLPLUS (as system): create public database link mysql connect to "oracle" identified by "123" using 'dg4odbc';
e. select * from test@mysql ("test" is a simple table I created in the MySQL DB) returns
ERROR at line 1:

libc.so.6 => /lib/libc.so.6 (0x005b1000)
/lib/ld-linux.so.2 (0x00736000)
So it can find and load the necessary libraries (afaik)..
So any ideas left??

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.

Database link from oracle to db2

Can any help me to create a database link from oracle to db2. It would be greatful if you can provide me detail steps

You don't give us much information to go on. What version of Oracle? What platform is DB2 running on? You might want to take a look at this. You might also look here and here.

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?

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.

How to Create Public database link in oracle 9i?

Friends,
OS: RHEL AS 3
DB: 9iR2
database name 1 = nubul
database name 2 = test
in the 'nubul' database server using system user.
i created a database link to connect the 'test' database
sql> create public database link test using 'test';
database link created.
then i logged in as normal user....
sql> select count(*) from employee@test
Error at line 1:
ORA-12154: TNS: could not resolve service name
where i am making mistake?
i gave the linkname as my remote database name.
am i have to make any entry in the tnsnames.ora?
thanks & regards

You have to remember that when you access a dblink, the database where the link is defined is acting as a client to the database to which the link points ... exactly the same as if you you were using sqlplus on the machine hosting the db where the link is defined. In other words, given:
Host 'Host-src', with database 'db-src', with a dblink 'lk_target'
Host 'host-trgt', with database 'db-trgt'
When you connect to db-src and access lk-target, db-src is now acting as a client to db-trgt. Exactly as if you had opened sqlplus on host-src and connected directly to db-trgt. So, given the above scenario
host-src$> sqlplus scott/tiger@db-src
sql> select * from emp@lk_target;when you execute that SELECT to the link, the same tns considerations are in effect as if you had
host-src$> sqlplus scott/tiger@db-trgtThe same tnsnames.ora entry, on the source machine, is required for both.

Database link from Oracle 11g (64 bit) to MySQL over UnixODBC with dg4odbc

Hello,
I want to connect to a MySQL Database from Oracle over a database link, but i get always the Error Message ORA-28528: Heterogeneous Services datatype conversion error .
In the forum or internet I can't find a solution for my problem, so I try now to post this problem.
Here a detailed description of the problem:
I use a Oracle 11.1.0.7.0 64bit database which is running on a redhat linux 5.3 64bit.
I want to connect to a MySql Database 5.0, which is running on a redhat linux 5.2 32bit over unixODBC.
The configuration from the ODBC seems to be good, because with isql on the ora server I can connect and query all data correct from the MySQL database.
Also the tsnnames.ora and listener.ora should be configured correctly. The tnsping works also fine.
But when i try to catch the data over SQLPlus with the database link I always get the error ORA-28528.
If I try to select just one column it works, but the returned data are incomplete or truncated.
the version of my libs:
between mysql and odbc I use libmyodbc3.so version 3.51.12-2.2 (I also tried the version 5, but with them I get a segmentation fault error on isql).
between odbc and dg4odbc I use libodbc.so version 2.2.11-7.1
Has anybody a solution or hint for me?
Many Thanks in advance,
best regards from Austria
Manuel

Database link from Oracle DBMS 1g to MS SQL Server

Hi,
I would need to know, if there is some out of the box functionality from the Oracle DBMS 11g where I can connect to MS SQL Server (2005/2008)? If there is good tutorial on how to do it, I would very much appreciate it.
Thanks!
Dejan

Hi,
I have created following:
1. Oracle DBMS 11g Enterprise installe (guessing that also the ODBC drivers for Oracle should)
2. Using MS SQL 2009 Native Client for ODBC connectivity
3. global_names set to false by
alter system set global_names=false;
4. Configures Oracle Heterogeneous services in initHS_ORCL.ora under \hs\admin to
HS_FDS_CONNECT_INFO = HS_ORCL
HS_FDS_TRACE_LEVEL = off
5. Modified listerner.ora to
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = ORCL) (ORACLE_HOME = C:\oracle\product\11.1.0\db_1) (SID_NAME = ORCL) ) )
LISTENER = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = nt-topobase)(PORT = 1521)) )
# Connecting to MS SQL Server via ODBC
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = HS_ORCL) (ORACLE_HOME = C:\oracle\product\11.1.0\db_1) (PROGRAM = hsodbc) ) )
6. Modified TNSnames.ora to
ORCL = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = nt-topobase.cgs-lj.si)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ORCL) ) )
# Connecting to MS SQL Server via ODBC (added newly)
HS_ORCL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS= (PROTOCOL = TCP) (HOST = nt-topobase) (PORT = 1521)) (CONNECT_DATA = (SID=HS_ORCL)) (HS=OK))
7.Restarted Oracle service
8. Created Database link for an existing user sz that is sysdba in the ORCL instance:
create database link hs_orcl connect to sz identified by admin using 'HS_ORCL';
Database link created.
9. Tried logging:

ODBC connect from Oracle to MySQL!

Dear All,
I know its not very much related to the subject of this forum but DBA's often have to perform such tasks.
I am in process of developing replication between Oracle and MySQL. For this I have planned to create materialized views in oracle that query MySQL database.
I am using Oracle 11gR1 on Linux for Oracle Server and MySQL is on windows based server version is 5.1.
I am stuck at the very first step that is to create a database link between Oracle and MySQL.
On Oracle's server, I did the following:
Installed unixODBC rpm (Installed successfully)
Installed mysql-connector-odbc (Installed successfully)
when i write this command odbcinst -j it gives the following information
unixODBC 2.2.11
D|RIVER........... : /etc/odbcinst.ini ; (my comments : Files exists)
SYSTEM DATA SOURCE : /etc/odbc.ini (my comments : File exists )
USER DATA SOURCE : /root/.odbc.ini (my comments : File DO NOT exists)
Now i tried to add the following entry in the file /etc/odbc.ini
[bssdata]
Driver = MySQL ODBC 3.51 Driver
DATABASE = bssdata
DESCRIPTION = views_on_bssdata
PWD =
PORT = 3306
SERVER = 192.168.0.68
UID = root
Now when i try to check the connectivity with the command:
isql -v bssdata root
Error: data source name not found, and no default driver specified.
ERROR: Could not SQLConnect
Anyone have tried this before, please help me out of it.

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,
