Migrating data from SAP BW to Oracle

We have a requirement where the exisiting data from SAP BW needs to be migrated into Oracle. What are some of the major differences that we should keep in mind when migrating this data. Our first task is to generate the data model in Oracle. Can we use a tool such as SQL Data Modeler or ERwin to derive the logical model from SAP and use it to build the physical model in Oracle? Would this be possible? Can you share your experiences in building data models for data migration?

This is a very specialized area you are looking at. My recommendation is that you look at SAP sites on Oracle.com for assistance. There is also a SAP Migration white paper you can read and the Oracle/SAP site.

Hello,
just migrating a DB2 database to Oracle 10g might be an easy task. The Oracle Migration Workbench is the tool for such a migration:

I have no idea about SAP, and that might complicate the picture. But there exist specialists for this task:

Faster way to migrate data from SQL Server to Oracle 10g

We have to migrate data from SQL Server to Oracle 10 g.
One particular table on SQL Server has records around 1.25 millions.
We tried moving data using DTS package, but looks it will take hours with current speed of 300 records/minute.
This table has TEXT column, which has XML strings stored. I am not sure, if this is the reason for slow migration.
Would you please suggest better options to migrate it faster?
Thanks in advance !!!

Have you tried Migration work bench?

How to migrate data from MS Access to Oracle???????

how to migrate data from MS Access to Oracle???????

You can use heterogeneous services (HS) connection to MS-Access from Oracle and still use the same PL/SQL (or even a single CTAS statement) or SQL to load directly to Oracle tables. It's transparent, quick and clean as opposed to writing complex control files.
You might have to set the ODBC connection to your Access database and add the details to Oracle listener.
Please let me know if you are not sure how to set up the connection.

Issues Migrating Data from SQL Server to Oracle

Good morning, I'm currently trying to migrate data from a SQL Server 7 Database to Oracle 11GR1.
I've followed the steps outlined in the guide that's on OTN and for the most part it worked well, the Data Model Capture, transformation and generation worked fine but when i try to do an online data migration the parallel DataMove threads stop working, i have no errors at all on the migration log they just don't pickup new tables to migrate data.
After looking at the last tables they tried to migrate i noticed that this happens when the table has a text, timestamp or image column on Sql Server which translate to CLOB, RAW[50] and BLOB columns on Oracle.
I'm i missing something here or just flat out doing something wrong with these datatypes?
Oh btw i'm using SQL Developer 2.1 December Edition plus the jtds 1.2.5 drivers for SQL Server.

As you don't have an error message it is difficult to diagnose. You could perform the offline data load for those failiing tables and continue to use the online method for all others.
Another option would be to log a service request and to provide some demo data to analyse the root cause.

Migrating data from one databaes to oracle?

is there any way to migrate my data from my old/previous database to oracle db.
ie. migrating data from one databaes to another.

If you are using Oracle 9i, look at external tables. Otherwise, dumping your data to text files and using SQL*Loader to load it into Oracle tables is a good option. There are various tools and utilities you might look into, including ODBC and migration toolkit. I prefer the SQL*Loader method for DBase, FoxPro, and Access.

Need help in migrating data from SQL Server to Oracle

Hi,
I've created a database link in my Oracle Database 11g Express Edition connecting to our SQL Server 2005 Enterprise Database. Now, I'm having issues on migrating some fields. Mostly Text field in SQL Server to CLOB in Oracle. I've created a PL/SQL Procedure to do this but somehow these columns don't get all the value.
For example:
In my sql server, I have a table SQLTBL with a field REMARKS of TEXT data type. It has the following value.
This is line 1.
This is line 2.
This is line 3.
Now I created a table ORCLTBL in oracle with field REMARKS of CLOB data type.
In my procedure I do something like.
begin
for i in ( select "remarks" rem from "dbo"."sqltbl"@sqldb )
loop
insert into orcltbl ( remarks ) values (i.rem);
end loop;
commit;
end;
/When I select the data from oracle it will only show "This is line 1" and disregard the values after the new line character.
Is there a way to make this work?
Thanks,
Allen

Does the above mean, you have Three records or it is One record spanning in Three lines?
Now I created a table ORCLTBL in oracle with field REMARKS of CLOB data type.

for i in ( select "remarks" rem from "dbo"."sqltbl"@sqldb )

Probably, assuming that there is only One record, SQL server is sending the data as separate rows as opposed to a Single Row.
Can you provide the Output of below when executed from Oracle terminal? (I hope you understand the motive of query, and pardon my knowledge of SQL Server if the query below does not work :) )
select count("remarks"), "remarks" rem from "dbo"."sqltbl"@sqldb group by "remarks";

How to join data from SAP BW and Oracle database from Webi?

Hi,
Need to create a Web Intelligence Report connecting to multiple data sources.
Ø SAP-BW contains the data (All units).
Ø Oracle db contains the access security data (respective units
for the user).
Since Universe can only connect to a single data-source we have to create two universes connecting to SAP-BW and Oracle db respectively and then create a webi report to point the two universes to retrieve the equi-join data on the report.
May I know which layer I can join the data? What kind of data I can join?
Can I merge dimensions from both the data sources? What about measures?
How I can create SQL query in Webi in order to simulate the join to the two data source?
Appreciate any info related.
thanks and regards
nora

Hi Nora,
You can use Data Federator technology to federate multi-sources such as SAP BW and Oracle.
Las you just have to create a universe on the Data Federator data source and the universe isee the data source as a single source whereas it is not.
Then any clainet that consume uninverses can take advantage of this solution.

Migrating data from MS-Access to Oracle DB

Hi All,
We are planning to migrate MS-Access data to Oracle Database. Can you please let me know how to resolve this one? Can you please share me if there is any script for this or let me know if any tool is available. I have SQL developer in my system.
Thanks

You're in luck - SQL Developer is our official migration tool.
Read the docs and let us know about any specific questions you may have
http://www.oracle.com/technetwork/products/migration/access-084991.html
Note you'll be migrating the tables and data, not necessarily the forms/reports/application bit of the Access database you're working with.

How to only migrate data from SQL Server 2008 to Oracle 11?

According to our requirement, We need to only migrate data from a SQL Server database to an existed
Oracle database user.
1) I tried to do it with SQL Developer 3.0.04 Migration Wizard, But find an issue.
My SQL Server database name is SCDS41P2, and my Oracle database user name is CDS41P2;
When I used SQL Developer to do offline move data by Migration Wizard, I found all oracle user
name in movedata files which gotten by run Migration Wizard
is dbo_SCDS41P2. If the Oracle user name is not the same as my existed Oracle user name,
the data can't be moved to my existed Oracle user when I run oracle_ctl.bat in command line window.
So I had to modify the Oracle user name in all movedata files, but it's difficult to modify them because there are many tables in
databases. So could you please tell me how to get the movedata files which the oracle user name in them is my
expected Oracle user name?
2) I also tried to use the 'copy to Oracle' function to copy the SQL Server database tables data
to the existed Oracle database user. When clicked 'copy to Oracle', I selected 'Include Data' and 'Replace' option
But I found some tables can't be copied, the error info is as below:
Table SPSSCMOR_CONTROLTABLE Failed. Message: ORA-00955: name is already used by an existing object
Could you please tell me how to deal with this kind of error?
Thanks!

Hi,
Thanks for you replying. But the 'copy to oracle' function still can't be work well. I will give some info about the table. I also search 'SPSSCMOR_CONTROLTABLE' in the target schema, and only find one object. So why say 'name is already used by an existing object'? Could you please give me some advice? Thanks!

Transfer Of Data from Sap to Oracle with the help of Enterprise Services.

Hello,
We want to transfer data from Sap to Oracle using standard Enterprise Services.Some fields were not available in the existing standard Enterprise Services,so we have enhanced the existing Services by writing code inside BADI available with Enterprise Services.Rest of the fields we have mapped with the existing fields available in standard Enterprise Services.But,the Oracle people want to fetch all data from Sap without entering any input as a mandatory field in the Enterprise Services.The existing standard Enterprise Services require to enter any field as mandatory and are not accepting the range in input for multiple records.e.g.All enterprise Services related to Sales Orders are displaying only one sales Order.We have searched all Enterprise Services for Sales Order(related to reading of data),but not able to find service which would display mutiple records without entering any input.ECC_SALESORDER009QR is the only service which is displaying multiple records without entering any input,but the required fields are not available in this service.So,kindly suggest what we need to do further.
1.Should we go for customization of services completely,so that it would fulfil our requirement.
2.Are there standard Enterprise Services exists which would we give us data in range(all records).
If they exists,please specify the names of Services for reading Purchase Order,Production Order,BOM etc.
Thanks & Regards,
Divya.

Hi Vaibhav,
Let me tell you the objective in detail.
Objective.
To develop a package solution which will work as a bridge between Oracle APS and SAP system so that customers using SAP will be able to use advantages of Oracle APS for their planning needs.
This will consist of following major components:
OA Templates is an Oracle utility to load data from any legacy system to Oracle APS using standard flat files.
Oracle has developed an Application Integration Architecture which is a standard architecture used for integration of Oracle products with other systems.
Enterprise services is an SAP utility to communicate with SAP.
AIA canonicals are standard canonicals developed by Oracle where we have to map data fields from destination system (Oracle APS) and source system (SAP)
Fusion middleware is being used to develop application interfaces following AIA standards.
Tasks at stake:
Mapping of Oracle APS fields and SAP Enterprise Service fields to AIA canonicals
Technical work of developing middleware using Oracle Fusion
From Sap side,we have to map fields which we have received from Oracle with the help of Enterprise Services,rest consumption of these services is done by Oracle guys.So,suggest is there enterprise services available which would give us multiple records .
Thanks & Regards,
Divya.
