DB links Oracle to Sql server

Hi All,
I am planning to create DB link from oracle to sql server 2005.
Please provide the doc for creating db link from oracle to sql server 2005 and also let me know is their any freeware to do the same.
Regards

It would be helpful if you could mention which platform your Oracle database is running on and which word size the OS is (32/64bit).
The free solution would be to use the Database Gateway for ODBC (=Dg4ODBC) and install it on a MS Windows platform or on Linux 64bit as for these 2 platforms Microsoft offers a free ODBC driver. On all other platforms you have to purchase an suitable ODBC drivers from a 3rd party vendor like DataDirect. I know, some people here on the Forum are using FreeTDS but this driver is not a good choice when using it in production.
Starting with the documents where you can build up a database link without additional costs:
Please have a look at the documents available on My Oracle Support portal:
How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on 64bit Windows Operating Systems to Connect to Non-Oracle Databases Post Install [ID 1266572.1]
How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on Windows 32bit to Connect to Non-Oracle Databases Post Install [ID 466225.1]
and
How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on Windows 32bit to Connect to Non-Oracle Databases Post Install [ID 466225.1]
As mentioned for other platforms you commonly have to purchase a 3rd party ODBC driver and depending on the licensing costs this 3rd party ODBC driver might be more expensive the using Oracle's commercial product, the Database Gateway for MS SQl Server. It is designed for MS SQl Server connections and much more powerful then DG4ODBC - for example it allows you to call remote SQL Server stored procedures or to participate in distributed transaction.
Documents about DG4MSQl can be found also on Oracle's support portal.

DB LINK Oracle to SQL Server SQL Server TimeStamp converts to Oracle Date

Hi All,
I have created a DB link between Oracle 10g 10.2.0.5 to SQL server 2005 using Oracle 11g gateway. When I execute a query from Oracle that selects data from SQL server using the DBLINK then the column value of type Timestamp from SQL server gets converted to Date data type in Oracle and it losses the time value.
Is there some way (in gateway configurations or in select query sql ) that the SQL server data type Timestamp gets converted to Oracle's Timestamp?
Please help.
Best Regards!
Irfan
Edited by: irf_mas on Mar 13, 2012 3:23 AM

You're getting the ORA-2070 error as the gateway that you are using is not supporting the to_timestamp function in this context. You need to rewrite the code.
Best would be if you first check out the data format that is sent as a string when you just select the date column - for example:
data_create_dt
Jan 11 2012 1:40PM
Now the easiest way is to make sure the format you are using in your where clause matches the string from the SQL Server:
select * from "data_ms_view"@FREETDS_DG4ODBC_EMGTW_11_2_0_3 where "data_create_dt"<'Jan 11 2012 1:41PM';
which will result in:
data_create_dt
Jan 11 2012 1:40PM
BTW,
it works with all formats the SQL Server understands:
SQL> select * from "data_ms_view"@FREETDS_DG4ODBC_EMGTW_11_2_0_3 where "data_create_dt">'11-JAN-12 01.40.00.000000000 AM';
data_create_dt
Jan 11 2012 1:40PM
Another way using binds:
SQL> variable datum varchar2(26);
SQL> exec select to_char(systimestamp,'MON dd yyyy hh:mi') into :datum from dual;
PL/SQL procedure successfully completed.
SQL> print datum
DATUM
MAR 19 2012 08:29
SQL> select * from "data_ms_view"@FREETDS_DG4ODBC_EMGTW_11_2_0_3 where "data_create_dt" <:datum;
data_create_dt
Jan 11 2012 1:40PM
There are several ways to get a result, just make sure you don't use an unsupported function in your statement. A list of supported functions is found in the manual.

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.
Regards,
Nith

use the like to setup ODBC and datasource

and then create link server in sql server after you test connenction with oracle

Oracle DB Link from Oracle to SQL Server

I am trying to create a dblink from Oracle to SQL Server.
This is my tnsnames.ora

   (CONNECT_DATA=(SID=sq))
   (HS=OK)

)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.

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?
Justin

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.

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_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))

Oracle and SQL Server Database Link errors

I am having following error messages while setting up the ODBC connection. I want to access SQL Server tables from within Oracle8i. I have followed all the instruction of Oracle Generic Connectity document and have tested ODBC connection with ODBCPING as well as with TNSPING. Have created Database Link also within Oracle for SQL Server. But when I access the SQL Server table from within Oracle I get the following error messages.
ORA-12500: TNS:listener failed to start a dedicated server process
Could any body suggestion the solution please.
Thanks and regards,
Ghulam Mallah

There is a Heterogenous Services/ Generic Connectivity forum that is probably going to have a lot more people familiar with these issues than you'll find in this forum. I would suggest posting over there.

Hi ,
Thanks for your reply.
Contents of my initMYSQLSERVERDSN.ora file is
# 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 = MYSQLSERVERDSN
HS_FDS_TRACE_LEVEL = 0
HS_FDS_TRACE_FILE_NAME = hsmsql.trc
# Environment variables required for the non-Oracle system
#set <envvar>=<value>
set ODBCINI=c:\WINDOWS\ODBC.INI
SALIHKM.DOMAIN.COM is my system in which Oracle Test DB is Installed.
SQL Server is in another location.
In Tnsnames i specified ip address.
One more doubt.
I am using 10g Release 2 demo version.
whether it will support Hetrogeneous Services?
How to know whether a database supports HS or not?
Thanks & Regards

Developing database views between Oracle and SQL Server tables

I am on Oracle 10.2, my organization has many SQL Server databases as well and has now made
SQL server as company standard so many new databases will be developed in SQL Server. It is of course
not possible to convert all Oracle databases to SQL Server, so a mix environment will exist. Two questions:
1. Is it possible to develop database views in Oracle (10g in my case) which join Oracle tables with tables in SQL Server 2008? If yes, how. I have seen some heterogeneous connectivity setup to connect SQL Server to Oracle, but not sure whether it is possible to develop a database view across two databases.
2. I know it is not a SQL Server forum, but many DBA’s know both Oracle and SQL Server. Is it possible to develop views in SQL Server (SQL Server 2008 R2 in my case) which join Oracle 10g and SQL Server 2008 tables? I know in SQL Server, there is way to set up linked servers, but do not know whether it is possible to develop views.
Thanks a lot for your insight.

You can create views that join local Oracle tables and remote SQL Server tables. I'm pretty sure you can do the reverse as well but I haven't personally done it.
However, I would be very concerned about the performance you'd get if you created that sort of view. You'd very frequently end up in a situation where Oracle has to pull all the data in the remote table across the database link in order to apply predicates and join the data locally. That could be disastrous from a performance standpoint.

First of all please be aware HSODBC has been desupported since 15th of March 2008. When starting a new project you should start with a supported product and this product is called DG4ODBC and it is available as release 11.
Looking at the provided listener it shows several configurations issues.
Have a lokk at yout tnsnames.ora => you mentioned to use the listener servicing port 1521.
This Listener serves 2 SIDs with the same name:
SID_DESC =
(SID_NAME = yscc02)
(ORACLE_HOME = /u01/app/oracle/product/101)
(PROGRAM = extproc)
(SID_DESC =
(SID_NAME = yscc02)
(ORACLE_HOME = /u01/app/oracle/product/101)
(PROGRAM = hsodbc)
(ENVS = "LD_LIBRARY_PATH=/u01/app/oracle/product/101/lib32:/usr/lib:/u01/app/oracle/product/101/hs/lib32")
So when you now connect, the listener does not know which service to spawn. Please check out Metalink note:
Note.238771.1 How to Setup Generic Connectivity - HSODBC - on AIX
when you want to continue using HSODBC although I strongly recommend you to use DG4ODBC which is configured as mentioned in Metalink note:
Note.561033.1 How to Setup DG4ODBC on 64bit Unix OS (Linux, Solaris, AIX, HP-UX)
