Replication sql server to oracle

Hi all,
Anyone here good at replication?
Can you help me what freeware, or poor woman's script, or cheaper tool (compared to GG) to replicate table from sql server to oracle?
I tried googling it but it just too complex to understand :(
Please help....
Thanks,
zxy

There is a world of difference between a latency of 1 minute and a latency of 30 minutes. If you don't know for sure what sort of latency you can tolerate, you'll really need to figure out your requirements before anyone is going to be able to help.
If you can tolerate a 30 minute latency and you can identify changes that need to be replicated from the SQL Server side, you may be able to cobble something together by using Heterogeneous Services to create a database link to SQL Server and scheduling a job in Oracle to run every, say, 15 minutes to replicate the changes. Assuming that you don't want to buy the SQL Server gateway, that would involve using the ODBC gateway. If your Oracle database is on Windows, that's not too big of a deal. If you're on something other than Windows, that would either require that you license a SQL Server ODBC driver that runs on whatever operating system you use (which will likely cost less than GoldenGate but more than nothing) or it will require a non-standard configuration where the gateway is installed on the machine that SQL Server is running on (or you could introduce a third Windows box that just runs the ODBC Gateway).

Replication SQL Server 7 Database to Oracle 9i

Hi -
I'm new to Database Replication, what are the steps for database replication from a MS SQL Server 7 database to Oracle 9i? Eventually this SQL Server Database will be going to SQL Server 2000 are the steps different, if so what are they?
Thanks
Much

I do not what you mean with Replicate between SQL Server and Oracle. Perhaps you mean migrate from SQL Server to Oracle or to stablish a transparent gateway.
I am going to give you this reference:

One way replication from MS sql server to Oracle 10g

Hi,
We are using Sql server 2005 windows 2003 32 bit and Oracle 10g 10.2.0.3 on linux 64 bit
Is it possible to replcate table data on real time from sql server (2005 32 bit or sql server 2000 32 bit)to oracle 10g running on linux 64 bit?
If yes then what are the steps.
It will be one way replication from sql server to oracle.
Which option is best sql server dts or Oracle Stream replication to replicate table data?
Regards,

If you want to push data from SqlServer, then ODBC, Linked tables, DTS etc.
If you want to pull data from Oracle, then Heterogenous Services / Gateway.

How to replicate data from MS SQL Server to Oracle

Hi,
Can someone please help me on how to replicate data from MS SQL Server to Oracle 8i database.

Dear,
I'm a student.
I do simple replication on Oracle 8.0.5 successfully. (one master site and one snapshot site). I only use the SQL*Plus and Schema Manager to do.
But when I do advance replication (multimaster replication) I meet many problem. So I don't get the result.
Do you show me the technology to do that ?
Thanks !

Migration from MS SQL Server to Oracle 10g

Hi,
In our application, we are planning to refresh data every one hour from MS SQL Server to Oracle 10g. Can anyone tell me what approach can be followed?
Thanks & Regards,

Hello,
migrations can be done with the Migration Workbench that is included in the SQL Developer: http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
But your question sounds more like a replication of data than a migration. Please read as a starter the following note in My Oracle Support (former Metalink):
Note 283700.1: How to replicate Data between Oracle and a Foreign Datasource
That note describes ways for the replication in both directions. Please let me know whether this is helpful for you.

Replicating data from SQL Server to Oracle

I like to know whether it is possible to Replicate data from SQL Server to Oracle and vice-versa.
My present application is using SQL server and very recently we migrated to Oracle. As the usage of SQL Server is more, I like to replicate the data being entered into SQL Server into Oracle also.

You can also use SQL Server replication right out of the box to replicate data to Oracle. In Enterprise Manager, configure an OLE-DB or ODBC subscriber with the Oracle credentials, and then just create a standard push subscription to the newly configured Oracle subscriber. Note that you need to click the advanced checkbox on the subscription wizard to see the heterogeneous datasource as a subscriber.
Good luck,

Capture Changes from Sql Server using Oracle Streams - Destination Oracle

Is it possible to capture changes made to tables in Sql Server database and propagate the changes to Oracle Database using Oracle Streams and Heterogeneous Gateway. I see plenty of information about pushing data from Oracle to Sql server, but I haven't been able to find much information about going the other way. Currently we are using sql server 2005 replication to accomplish this. We are looking into the possibility of replacing it with streams.

the brief understanding i have is that there is nothing out of the tin that Oracle provides to stream between SQL Server and Oracle. The senario is documented in Oracle docs however and says you need to implement the SQL Server side to grabe changes and submit to Oracle stream queues.
i'm sure i've seen third parties who sell software to do this.
If you know otherwise please let me know. Also wasn;t aware one could push from SQL Server to Oracle. Is this something only avail in SQL Server 2005 or does 200 also have it? How are you doing this?
Cheers

Depending on the version of the database you have, you could use transportable tablespaces.

Entity Framework - Code First - Migration - How to access SQL Server and Oracle using the same context?

Hello,
I use Entity Framework code first approach.
My project is working fine with SQL Server. But, I want to access Oracle too. I want to switch SQL Server and Oracle in run time.
I am able to access Oracle using "Oracle.ManagedDataAccess.EntityFramework.dl" in a new project.
But, Is this possible to access SQL Server and Oracle in the same project.
Thanks,
Murugan

This should be possible with a Code-First workflow. In Code-First the database mapping layer is generated at runtime.

How to connect to a Sql server from Oracle using db link

Hi All,
Does anybody have any idea about how to connect to a sql server from oracle database using db link to syncronize the data? I need to pull the data from Sql server table to Oracle tables and relay messages back to the sql server.
Thank you,
Praveen.

we have 2 products - DG4MSQL and DG4ODBC.
DG4ODBC is for free and requires a 3rd party ODBC driver and it can connect to any 3rd party database as long as you use a suitable ODBC driver
DG4MSQL is more powerfull as it is designed for MS SQL Server databases and it supports many functions it can directly map to SQL Server equivalents - it can also call remote procedures or participtae in distributed transactions. Please be aware DG4MSQL requires a license - it is not for free.
Check out Metalink and you'll find notes how to configure both products.

Related to migration of db from sql server to oracle 11 g

We're trying to migrate a Sql server managment studio database to Oracle 11g using SQL Developer 4.0. We can successfully connect to both Sql server managment studion 8.0 and Oracle 11g using the tool, as well as click through the Migration Wizard and start the migration.
This opens the Database Migration dialog box, which indicates the capture process starts normally. we get the following error:
ora :01440 : can not insert null into migrlog (id column) ,
\and then after some time , i get an error that migration failed
i am not getting the reason,I thing it may be due to reason that , I have table's column in my source db with more than 30 character.
If i am migrating one by one table . then it is not giving any error, and identifier name is getting shrink in 30 character. but i am not getting the view , stored procedure , indexes , and others
then what is the solution for that, somebody pls suggest any help?????????????

Pl do not post duplicates - related to migration of db from sql server to oracle 11 g
Continue the discussion in your original thread
The error message is explicitly clear
ora :01440 : can not insert null into migrlog (id column)
Your process is trying to insert a NULL value into the ID column, which presumably cannot be NULL

Different output of same query in SQL Server and Oracle

I have two tables table1 and table2
--table1 has two columns c1 int and c2 varchar. there are not constraints added in it. it has data as given below
c1     c2
6     d
5     j
102     g
4     g
103     f
3     h
501     j
1     g
601     n
2     m
--table2 has only one column c1 int. there are not constraints added in it. it has data as given below
c1
6
1
4
3
2
now when i run below given query in sql server and oracle it gives me different result
select *
from table1
     inner join (SELECT ROW_NUMBER() OVER (order by c1 ASC) AS c1 from table2) table2 on table2.c1=table1.c1
sql server output
c1     c2     c1
1     g     1
2     m     2
3     h     3
4     g     4
5     j     5
oracle output
C1 C2 C1
5 j 5
4 g 4
3 h 3
1 g 1
2 m 2
If you notice the first column in both output. It is sorted in sql server and not in oracle.
Why it is behaving differently in oracle? Is there any way I can solve this in oracle?
Thanks,
Jigs

It is NOT behaving "differently" in Oracle; you just haven't specified an order that you expect your results to be in, so you're going to get output in whatever order the database fancies displaying it (ie. no guarenteed order). This is an artifact of how the database chooses to put together the data, and different databases (or even datasets within the same database) can and most likely will behave differently.
Even SQL Server won't guarentee to always get your data in an ordered fashion if you exclude the order by clause, even if you think it has always output the data in an ordered fashion.
Your solution is to add an order by clause, in BOTH databases, to force the order of the output data.

CONVERT function in SQL Server to oracle

All,
How to convert CONVERT function in SQL Server to oracle, below mentioned format is in SQL Server:
variable1 = convert(numeric(20), SUBSTRING( parameter1,parameter2,parameter3)
parameter1 datatype nvarchar2(100)
parameter2 datatype bigint
parameter3 datatype bigint
I did bit R&D, but was not successful..but still getting on..
If any help that would be great...
Regards,
~ORA

You cannot specify the precision/scale or length of input paramters to a stored procedure in Oracle, or at least the pl/sql engine does not respect the sizing. Assuming that you want to do something with variable1 in the procedure, and not just return it, the Oracle equivalent would be something along the lines of:
SQL> CREATE FUNCTION f (p_param1 IN VARCHAR2,
2                     p_param2 IN NUMBER,
3                     p_param3 IN NUMBER) RETURN NUMBER IS
4     l_var1 NUMBER(20) := SUBSTR(p_param1, p_param2, p_param3);
5 BEGIN
6     RETURN l_var1 * 10;
7 END;
8 /
Function created.
SQL> SELECT f('ABC10DEF', 4, 2) FROM dual;
F('ABC10DEF',4,2)
              100You may need to adjust the return type to match what you are actually returning.
You can also use this iin a direct assignment in pl/sql without doig a select, something like:
SQL> DECLARE
2     l_num NUMBER(20);
3 BEGIN
4     l_num := f('ABC10DEF', 4, 2);
5     DBMS_OUTPUT.Put_Line('The number is: '||l_num);
6 END;
7 /
The number is: 100John
