Data from BW to Oracle.

Hi All,
I am new into BW and i know how to get the data from my applications backend i.e ORACLE to BW system for reporting purpose. I have a scenario where user can edit this information through IP. I want this modified data to go back to ORACLE DB so that i can use this in my webdynpro application for further processing.
So how can i achieve the transfer of data from BW to ORACLE DB in real time.
Hope i am clear and will get some solution for this.
thanks & regards,
Manoj

@Jai
no, it's not DBCONNECT.
Database links are an ORACLE feature that comes for free if you have Oracle on both sides.
Main steps for the implementation part:
BW side:
1. you have to invite the Oracle database in the protocol.ora file of the MY_BW database.
The host is the server where the local Oracle database instance is running.
protocol.ora:
TCP.INVITED_NODES= (myORACLEserver,...other hosts...)
2. Define a database user in the BW database MY_BW_USER
3. Grant SELECT privileges for the user MY_BW_USER that is used in the link:
grant select on my_bw_table to my_bw_user;
Oracle side:
1. database link
CREATE DATABASE LINK "MY_BW.WORLD" CONNECT TO "MY_BW_USER"
    IDENTIFIED BY "my_bw_user_password"
    USING '(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (COMMUNITY = SAP.WORLD)(PROTOCOL = TCP)(HOST = mySAPBWServer.com)(PORT = 1521))
    (CONNECT_DATA = (SID = MY_BW)(GLOBAL_NAME = MY_BW.WORLD))
2. Create a view with the SELECT to extract from BW via the link (listed after the @):
Create view view_extract_from_bw as
select * from my_bw_table@MY_BW.WORLD
You can do any transformations in the SELECT part to fit the data into the local Oracle table later in the insert.
3. You will pull the data on the Oracle DB side from the BW database via the view that inturn uses the link
to the BW Oracle system:
insert into local_Oracle_table select * from view_extract_from_bw
You see some support is needed from Basis guys to establish the link. But once implemented
you have a interface from your local Oracle to the BW database.
bye

Upload data from excel to oracle table

Hi,
if i'm user and using an application and i want to upload data from excel to oracle table on button click . Is it possible by using sql loader.
If yes then please clarify it .
is it possible from client end.
thanks
kam

Yes it is possible using SQL*LDR, External tables and ORCL Export Utility. Though I didn't try Export Utility to load the external files.
SQLLdr sysntax:
Create a control file.
It looks like this
Load data
Infile 'source.dat'
Into Table tablename
Fields terminated by ',' optionally enclosed by '"'
{code}
then use sqlldr command from your OS.
{code}
sqlldr userid/password@sid control = filename.ctl, data = source.dat, log = logname.log, bad = badname.log, discard = discardname.discard
{code}

Data from Excel to Oracle DB

Hi,
I can upload data from excel to access having created stored procedure on access.
I do the upload using my vb code.
How can I upload data from excel to oracle db? could i use the same technique as above? only problem is im not sure if that vb code will work with oracle?
has anyone done this before? anyone have example code?
kindly assist me here
thanks

The easiest way to do this is to use a Oracle ODBC connection which can be found on OTN. You do not need a stored proc.
After installing Oracle ODBC on the machine where Excel and Access live, do the following.
Note, you already have steps 1, 2 and 3. I list all the steps for others.
1. Create your MS/Excel workbook
2. Add data to it.
3. Save it as "book1.xls".
4. Open MS/Access
5. Create new blank database, call it db1.
6. Then from the file menu, get external data, import, make sure the file type is xls, select book1.xls.
7. The wizard will walk you through the process of importing you Excel workbook into a new table.
8. Save
9. From the file menu select export table.
10. Select ODBC at the bottom of the "Save as type list".
11. Then (depending how you set up ODBC) select Machine Data Source.
12 . Select your Oracle ODBC connection and press OK.
You now have taken data from Excel to Access and placed it in the Oracle schema that was named when you setup your Oracle ODBC connection.

Generate Insert Statement Script to Extract Data from Table in Oracle 7i

Hi all, I have an old Oracle legacy system that is running for over 15 years.Every now and then we need to extract data from this table@ ORacle 7i to be imported back to Oracle 10G.
My thoughts are to create a script of Insert statements in oracle 7 and that to be deployed back to Oracle 10G.
I found this scripts in Google and not sure how exactly this works.Any explanation on thsi scripts , would be greatly appreciated.I find this scripst may help to generate a set of insert statements from that table to the latest table at 10G.

Thanks Justin.
I get what you are saying,i really wanted to see the output of the codes, because the furtherst i could get from that code is
SELECT EXTRACTDATA('MYTABLE') FROM MYTABLE;
and it generated this:
"select 'insert into MYTABLE ('||chr(10)||'DATE1,'||chr(10)||'TIME1,'||chr(10)||'COUNTS) values ('||decode(DATE1,Null,'Null','to_date('''||to_char(DATE1,'mm/dd/yyyy hh24:mi')||''',''mm/dd/yyyy hh24:mi'')')||','||chr(10)||''||decode(TIME1,Null,'Null',TIME1)||','||chr(10)||''||decode(COUNTS,Null,'Null',COUNTS)||');' from MYTABLE;

Read data from an external Oracle-DB: Codepage problems

Hi,
I try to get data from an external Oracle-DB which runs under NLS_CHARACTER
WE8ISO8859P1. In this DB are russian texte stored. If I read these texts via native-SQL I obviously get wrong characters. (e.g. Èíñòðóìåíòû äëÿ óãëîâîé øëèôîâàëüíîé ìàøèíû instead of Инструменты для угловой шлифовальной машины). If I save the text as a html file and then open it with IE. I can change the encoding and get the right view.
Has anybody got an idea ? (Mabye I can read the data in a different codepage or maybe there is a possibility to convert the codepage in SAP after reading it from oracle)
Thanks a lot !!!!

The problem is solved.
Many 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.

Sql loader loading data from legacy to Oracle

Hi
we have a requirement that we need to import data from legacy to oracle AR.We know that we need to put the data file in BIN folder,but I want to know about the data file source if we place in windows folder instead of BIN directory will SQL loader picks the file and loads the data.
Thanks
Y

Yes,
Refer this
http://www.oracle.com/technology/products/database/utilities/htdocs/sql_loader_overview.html
* Load data across a network. This means that a SQL*Loader client can be run on a different system from the one that is running the SQL*Loader server.
* Load data from multiple datafiles during the same load session
* Load data into multiple tables during the same load session
* Specify the character set of the data
* Selectively load data
* Load data from disk, tape, or named pipe
* Specify the character set of the data
* Generate sophisticated error reports, which greatly aid troubleshooting
* Load arbitrarily complex object-relational data
* Use either conventional or direct path loading.

How can i convert data from DBF to oracle database 10g?

Sir,
How can i convert data from DBF to oracle database 10g?

I assume you at least know how to dump the contents of foxpro dbf file into CSV format.
Regarding SQL*Loader, hope this demo makes it a bit clear to you...
http://www.princeton.edu/~storacle/sqlloader_demo.shtml
I agree that it is an old web page (references Oracle 8.0.5) but basics remain the same.
If it is still unclear to you after referring above link, then get an Oracle consultant.

Copy data from mysql to oracle database help?

Im an sql newb and trying to understand how I can automatically copy data from one dtabase to another systems database on the same server.
We have two differnt applications, but both share customer information, but one is on a win server, while the other is on oracle.
Each time a customer contacts us via online chat (win server, mysql), we want to copy their entire chat transcript into our CRM's (oracle) customer account. So the folks that use the CRM can see the past chat histories. I hope this makes sense.
Where can i look to get started on this?
Thanks

You could look at Heterogeneous Services (see the forum here Heterogeneous Connectivity but if you want to push data from mysql to oracle you might be better looking at it from the mssql side. I don't know what they offer.
It might be simpler to do it at the client end. ie cut and paste from the online chat application into a new utility which inserts into the oracle database.
Incidentally, this forum is specifically for the SQLDeveloper tool. You might get more general help in the "database - general" or "sql and pl/sql" forums

How to extract data from essbase to oracle database incrementally?

I have to extract data from essbase to an oracle database table incrementally using informatica , can anyone tell me how to do it or give me some tips. I have been thinking about it for a whole day but have no ideas.
I cannot do the delete & insert method because this oracle database table is a interface table that has to deliver the data to Oracle ESB tables.
Thanks in advance....

Import/insert data from XML into Oracle database tables?

Hi. (I am using JDeveloper 10.1.3.3.0 and Oracle 10g)
I have been able to export the data from one of my database tables by using a View Object and .writeXML.
Now, I want to take an xml file that is formatted in the same way as what is spit out by the writeXML and put that info in my database table. I followed online examples and have tried using .readXML like so:
Element element = XMLDoc.getDocumentElement();
vo.readXML(element, -1);
I know it is sort of working, because at first I got an error message that one of the required attributes was missing. So, I added that attribute to my xml file and ran my code. No errors. But, I checked my database, and the new records were not added.
Is there something I have done wrong? Or is there perhaps something I left out? I also noticed there were several versions of readXML like readFromXML. Which one should I use and how?
Thanks.

KUBA, I changed my code to match your example:
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
File xmlFile = new File("C:/myfilehere.xml");
Document doc = db.parse(xmlFile);
Element element = doc.getDocumentElement();
vo.readXML(element, -1);
vo.getDBTransaction().commit();
I still get no errors, but my database table has no new records.
Any ideas why?
Thanks.
