DB link between Oracle 9i and MS SQL server2000

Hi,
Is it possible to create a DB link between Oracle 9i and MS SQL server 2000.
If it is possible what are the different ways of creating it.
Is it possible without purchasing any propietery drivers.
Thanks,
Rohit

I've never seen any documents stating that the enterprise edition is a requirement for the heterogeneous connectivity ....
There are 2 ways to set up the connection with MS SQL - using generic connectivity driver (OLE DB or ODBC) or using the Oracle Transparent Gateway.
The generic connectivity is free and comes with Oracle DB - it has several limitations - for example you can't call MS SQL stored procedures from Oracle.
The Oracle Transparent Gateways are packaged , the MS SQL gateway is part of the Open System Gateways package ($15,000.00 per CPU license cost) and i has less restrictions.

Replication between Oracle Server and MS SQL Server

Hello,
Does anybody know of a well known or reliable software that can do data replication between Oracle Server and Microsoft SQL server.
I suppose I can write my own version using Heterogenous Services in Oracle but I would like to know if such an automated replication between Oracle and SQL is available commercially.
Thank you.

It could be very interesting.Sorry Viacheslav, even I couldn't find anything for the same. I am not sure that it can be done or not, I haven't heard anyone in my contact doing so. The only place where I have seen Streams being used around me is within Oracle db only. May be someone else can help if he/she has done it.

But you have to remember one big thing - I've not seen yet one compare that was completely indifferent to any of the included DB's. So you can be sure that every doc that you get on MS website will say that SQL server is better, every doc on Oracle website will say that Oracle is better. Every doc on other websites will say that better DB either is:
1) DB that has payed for the reserach paper
2) DB that was mostly used by the researchers
So of course you should be very cautious about each paper you get.

How to create ODBC connection between Oracle 10g and MS SQL Server

Hi,
Can someone help us with the steps to create an ODBC connection between Oracle APPS using Oracle 10g database and MS SQL Server.
Requirement is to extract the transactional data from MS SQL Server on a daily basis and dump it into Oracle tables for an interface to be run. Currently it is being done through Dataloader tool which we feel is causing the data issue with Arabic characters. We want to create the ODBC directly between Oracle and MS SQL Server and check if the data is being pulled correctly.
The data is in sql server 2000 which has data in Arabic_CI_AS character set which is moved to Oracle 10.2.0.3 database with characterset AL32UTF8. The table data is moved to oracle using the dataloader 3.6 standard edition licensed version. We cannot change the character set of Sql Server 2000.
Please help
Thanks
Shanil

Hi,
If you're trying to PULL data from SQLServer into an Oracle database, you wouldnt use Oracle ODBC driver for that, so you may want to post in the Heterogeneous Services forum instead:
Heterogeneous Connectivity
If you're trying to PUSH data from SQLServer into an Oracle database, you could use ODBC but most folks use OLEDB for that, and the following note on MOS should help:
How to Create a Sql Server Linked Server With The Oracle Provider for OLE DB (Doc ID 191368.1)
As with any NLS related issue, the first thing to do is dump the codepoints of the data in the Oracle database to see if it is stored validly, rather than relying on what the data "looks like" from some tool or other. It's best to check a single row, with only a few characters in it if you can, and you can do that via
SELECT DUMP(<columname>,1016) FROM <tablename> WHERE ...
Hope it helps,
Greg

DB Links between Oracle 11 and 8

Hello
What can I do, when I need a db link between an oracle 11 database and an oracle 8 database?
thanks. roger

The Problem is, that we have forget this database and now we can not update very fast. We searching for a solution.Roger,
you could try to put a 10g or 9i database as proxy in-between if you can't upgrade the 8i database, although it seems to be an awkward workaround.

Connection between Oracle 9i and MS Sql Server 2005

Hey Guys,
I am hoping to create materialized view of data on a small sql server box using our oralce 9i cluster. Anyway, i have done this with mysql using the standard odbc dirvers and a dblink, but i am having trouble finding an odbc driver for the connection from oracle to sql server. So, i was wondering if you guys know of a free, or cheap odbc driver, or have a suggestion of an alternative connection method.
PS: i have see: Heterogeneous Services Agents and Transparent gateways floating around, so are these options that don't need the odbc drivers and are free?
Thanks in advance

Database links between Oracle 10G and 7.1/7.3 & 8.0 databases

Hi All..
Unfortunately one of our customers is still using very very old unsupported versions of the database - 7.1 and 7.3 and 8.0. They wish to start an upgrade process - moving up to 10G (via staged upgrades) but wish to know whether they can still access information from old databases via database links.
I know that the Oracle 10G client cannot connect to database versions this old, and I am presuming that the database itself cannot via DB links but I thought it wise to check.
Any help appreciated. Thank you.

Oracle 10.1 is certified to connect to 8.1.7 and later. Database links to earlier versions are not certified and generally do not work.
The general solution to this sort of thing tends to be putting an older version of the database (8.1.7 or 9.0.1, usually) between the ancient databases and the new database. 10.1 can create a database link to 9.0.1. 9.0.1 can create a database link to 7.3.4 and create views that reference remote 7.3.4 objects that the 10.1 system can query. Of course, you're taking data over the network twice, so performance isn't ideal, but it can work in a pinch.

DB Link between Oracle 10g and Oracle 9i

Hi all,
Please help me to set the dblink between oracle9i and oracle10g.
Thanks in advance
Regards
K. Mahipal Reddy

Well... it depends on what type of link you wish to create.
If you have same user with same password on both databases (9i and 10G), then you can create a public database link as
CREATE PUBLIC DATABASE LINK dblink USING 'dbalias';
Note: dbalias is the value from your TNSNAMES.ORA. The database from which you are creating the db link has to have the entry in TNS for other database.
Other method is to create a private db link
CREATE DATABASE LINK dblink CONNECT TO user IDENTIFIED by pwd using 'dbalias';
The number of open connections from a particular database is governed by init parameter DB_LINKS (this was in 8i.. not sure about higher versions)

Link Between Oacle Payroll and Oracle Payables

Hi,
We have installed Oracle Payroll and OraclePayable.
I would like to know the link between Oracle Payroll and Oracle Payable i.e. If i run a Payroll process, does the same affect a Cheque Payment that i can see in Oracle Payable?
Can the same Payment format be used by Payroll and Payable?
If i use International HRMS, can i reconcile Payroll with Cash Management, as the GL Cash account field is not enabled for International HRMS on the Organisation Payment method screen?
Thanks in Advance.

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_NAME = PLSExtProc)
(ORACLE_HOME = G:\oracle 10g\oracle\product\10.2.0\db_1)
(PROGRAM = extproc) )
:> lsnrctl start LISTENER_NEW

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=

(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.

Please advise me to rectify the error. We've been working for the last couple of weeks.
Regards,

Sunil,
You don't need an Oracle ODBC driver.
The way it works is that in the gateway init<sid>.ora file, in your case initTelemetryDB1.ora, the parameter HS_FDS_CONNECT_INFO points to a system DSN. This DSN should then be configured to use an ODBC driver to connect to the non-Oracle database. So, in your setup when you want to access the SQL*Server 2008 database then the DSN should use an ODBC driver that can connect to a SQL*Server 2008 database. If you still use the initTelemetryDB1.ora file for the connection then the TelemetryDB1 DSN should be configured to access the SQL*Server 2008 database.
However, there are a couple of problems with your actual setup -
- the configuration you have - 10.2 RDBMS on a Sun machine and HSODBC on Windows - is not supported. HSODBC should only be used from a RDBMS that is in the same ORACLE_HOME as HSODBC.
- 10.2 HSODBC is now desupported and has been replaced by the 11g Database Gateway for ODBC (DG4ODBC) and the configuration you want is supported. That is because unlike HSODBC the DG4ODBC gateway can be installed standalone with a RDBMS being installed.
I recommend that you download and install 11.20.2 DG4ODBC on your Windows machine in a new Oracle_home and access that from the 10.2 RDBMS on Sun - which is a supported configuration. But to do this, you will need to apply either the 10.2.0.4 or 10.2.0.5 patchset to your RDBMS.
There is more information in the following note available on My Oracle Support (MOS) -
Note.1083703.1 Master Note for Oracle Gateway Products
The 11.2.0.2 DG4ODBC can be downloaded from MOS as patch and for the gateways on Windows 32-bit you just need to download -
p10098816_112020_platform_4of6.zip
However, to check the HSODBC ou need to confirm that the DSN used by HSODBC points to a System DSN configured to access SQL*Server 2008.
Have a look at -
Note 109730.1 How to setup generic connectivity (HSODBC) for Windows NT
But remember this is not a supported version or configuration and you should be using Dg4ODBC.

Mike
