Oracle Warehouse Builder - Interview Question.

Hi,
I am interviewing a person for a consulting role.
It has been about 4 years since I have even thought about OWB.
Can anyone suggest an interview question(s) (please provide answer) that would give a clear indication of their depth of use and understanding of OWB?
Thanks.

I disagree, but I sympathize with the interviewee who fears being asked an interview question by someone not knowledgeable enough to determine the correctness of their answer.
OWB is a tool which uses ETL concepts, but like most tools, has some quirks and idosyncracies which require some tool-specific techniques to be successful. I'm not an OWB user (a little Informatica, a little hand-coded), but have seen that setting up Type II SCDs in OWB looks like a very different exercise than setting them up in Informatica.
Hopefully somebody who developed their good conceptual undertanding of ETL before coming to OWB, and is now a good OWB user can give us some perspective on how important OWB specific knowledge is - and some questions to help seperate the OWB experts from the other ETL experts.

Oracle Warehouse Builder 10.1.0.4 on Windows 2008 - 64 bits

Hi Gurus.
I'm currently working with a customer who wants to migrate all their database-servers to Windows 2008 on 64-bits processors. They're using Oracle Database Enterprise Edition 10g Release 2 (10.2.0.4) and Oracle Warehouse Builder (10.1.0.4). The OWB-clients will still run on Windows XP. I've used the "Certify"-funcionality on Metalink, but it doesn't really answer my questions. (It does* ansver some of my questions, but it also raises a few new ones....)
My main question is: Can you run serverside OWB 10.1.0.4 on Enterprise Edition 10.2.0.4 for Windows 2008 64-bits?
Thanks in advance:-)
Best regards
Helge

No.
Oracle Warehouse Builder version 10.1.x was desupported on 16-JUL-2007.
The desupport notice is available on Metalink (Note 376384.1).
The Warehouse Builder installation as part of the 11.1.0.7 installation should be certified, but I cannot find specifics.

Where is Oracle Warehouse Builder 10g v. 10.1.0.1 ?

Hi, all
Where to download Oracle Warehouse Builder 10g v. 10.1.0.1
I have 10.1.0.4 but it refuses to work with 10.1.0.1.0 repository version

If you have more such questions you should have a look at the OWB forum:

Licensing about Oracle Warehouse Builder

Hi,
If we install trial version of oracle warehouse builder v 9.2 from oracle website, does anybody know whether all the functionalities of oracle warehouse builder are available or are there any restrictions in using the trial version of the oracle warehouse builder.
My second question is:
Do we need Oracle 9i database to install oracle warehouse builder.
After I installed Oracle warehouse builder when I clicked on start-->Programs-->Oracle 9i Developer Suite-->Warehouse builder-->OWB Client, when I open the OWB Client it's asking me for warehouse builder log on but it didn't ask for any username and password while I'm installing oracle warehouse builder. So, which username and password should I enter to log in to the OWB Client. And also can anyone please tell me what to enter into the Oracle Service name field.
Any help is appreciated.........
Thanks,
-Deepa.

There are no restriction in the warehouse builder version available from the OTN site. If you are using Warehouse Builder for commercial purposes (and if you want support and assistance from Oracle) you should pay for an Oracle Developer Suite license (as many of them as you have developers). currently it is $5000 per user (you also get JDeveloper, client Discoverer, BI beans etc.).
As for the OWB installation, you did not complete all the steps. After installing the software on your machine, you must install the design repository (this is when you will be asked to enter the user/password for the OWB client) and the runtime repository and schema (where you will deploy your data warehouse). For details, please read the installation and configuration guide (http://download.oracle.com/docs/html/B11000_02/toc.htm).

Oracle Warehouse Builder VS Oracle Data Integrator

Hi everybody,
I have a question that wish you can help me.
we have systems of x64 so we cant use Oracle Warehouse Builder (only support on system 32 bits), someone recommend us to use Data Integrator but i don't really know this application.
Anyway ODI 11.1.X.X could it be installed in x64:
All Oracle Fusion Middleware products that are indicated as certified on x64 processor based Oracle Linux 5.5 or 5 Update 5+, 64 bit operating system, are also supported on Exalogic X2-2.
What's is the different between OWB and ODI?
I read about it and see that ODI is powerfull and it apply "Data Quality" better than OWB, is it right?
Is it possible to exp/imp with metadata loader move metadates between OWB and ODI?

Hi,
well, the basic difference is hard to tell. ODI is based on so called knowledge module. This are implementations for physical access to all kind different database technologies (among ohter things). Therefore ODI used to be more flexible extracting data from different database technologies and also writing to them. But with OWB 11.2, these knowledge modules were integrated into owb as so-called template mappings. OWB has a stronger integration with the Oracle database and an Oracle database is always required. Oracle plans to integrate these two tools into one some day, whenever that will be. ODI offers more options for data quality (that are charged extra).
So technically, the two tools are not that different. They have different user interfaces anyway.
A big difference is the license. A basic version of OWB is included with the database license, so it can be used without extra charge. Most of our customers are using this version, even for large dwh implementations. If you buy am ETL license (or already have one), you may use both tools.
Before you decide on one of the tools, make sure you have enough manpower with the required skill available - internal or external.
Hope this helps,
Carsten.

Welcome to the Oracle Warehouse Builder discussion forum

Hello!
Welcome to the Oracle Warehouse Builder discussion forum!
Oracle Warehouse Builder (OWB) product management and development will monitor the discussion forum on regular basis.
Please use this forum for asking product related questions, giving feedback, suggesting enhancements, reporting problems and requesting collateral.

Bonjour "Etudiant from Tunisia",
I'm not sure what you mean with "please give me the user/password".
As far as I know there is no online OWB available where you could try out the product (if that is what you mean).
If you would like to learn more about OWB, read online documentation or for instance the link that is provided in an earlier post in this thread.
Otherwise simply install OWB and try it yourself. The Installation and Configuration Guide is clear enough even without much experience installing Oracle software, and the OWB User Guide provides some basic insight on working with OWB itself.
Good luck, Patrick
ps If people are still expecting what Igor mentioned when he started this forum ("Oracle Warehouse Builder (OWB) product management and development will monitor the discussion forum on regular basis"), don't count on it; fortunately the product itself has been around long enough now, there are quite some users that can share usable insights and/or drop some useful lines on the new threads... ;-)

Thanks for your reply Igor.
As posted the OWB 10.1.0 software is running against a 9.2.0.8.0. database, so OWB still uses DBMS_JOB instead of DBMS_SCHEDULER in this database. In addition I already tested scheduling a simple job to run an OS command as suggested in note 365539.1 , and job scheduling is working fine.
There are no invalid objects in this database.

Oracle warehouse builder - OWB & Oracle 10g Db on SuSE

hi folks,
i have Oracle 10g db on my laptop; and it runs great!
but since i am trying to gain skills in data warehousing and business inteligence, and after reading about oracle warehouse builder, i decided to install it on my laptop as well.
but i can not get my head around the docs for installing OWB.
is the only requirement for OWB to have an OWB_ORACLE_HOME environment variable on linux? how do we start OWB service automatically?
has anyone installed OWB with oracle on the same pc?
i would appreciate your comments.
thanks in advance,
Nicolas

Thanks Andreas,
i have printed and followed the advice on these documents.
that is how i have got confused about this OWB_ORACLE_HOME.
i would very much appreciate if could provide me with some brief description of which environment variables are needed for OWB installation.
regards,
nicolas

Oracle Applications Release 12 and Oracle Warehouse Builder 10gR2

Hi
I'm trying to deploying process flows to Workflow but I get the following error:
RPE-02054: The version of Oracle Workflow is incompatible with this Control Center. Required 2.6.3, but found 2.6.0.
Comment I found on another thread: "As far Workflow Versions with Oracle Applications is concerned, it is always 2.6.0. Workflow is not identified with its 2.6.x versioning in Oracle Applications. The 2.6.x.x versioning is purely for Workflow Standalone."
Oracle Warehouse Builder Client: 10.2.1.31
Oracle Warehouse Builder Repository: 10.2.0.1.0
Oracle Applications Release 12
Any help would be appreciated.

May be the excerpt from the other thread is a response I posted.
So, when you say, deploying process flows to Workflow, I do not understand what you are doing exactly? If this involves the Oracle Warehouse Builder you may want to explain a little more in detail since I do not understand how OWB works with Workflow. But as far as I have heard, it is Workflow standalone that is packaged with OWB but you are deploying into Oracle Applications.
What is the version of Oracle Workflow Builder you are using?
Is the steps you are doing certified to be done with Oracle Applications R12?
Thanks

Oracle Warehouse Builder 10.1.0.4

Hi All,
I am searching for Oracle Warehouse builder 10.1 release which is compatible with Oracle database 10gR2 on solaris x86 server.
I have found softwares for solaris sparc but nothing seems available for oracle 10gR2 on solaris x86.
OWB 10.1.0.3 is compatible with oracle database 10gR1 and owb 10.1.0.4 and owb 10.1.0.5 are only compatible with 10gR2.
Currently we are facing some problem with Owb 10.2.0.1 so we have to relay on owb 10.1 release.
Can any one help me to find link for downloading
OWB 10.1.0.4 or 10.1.0.5 for solaris x86 server...
Thanks

I am still unable to find any owb 10.1.x.x release for solaris x86 environment.
Do any one have any link for this??

ORA-06502 pl/sql in Oracle warehouse builder

Hi,
I have a problem with using Name and Address operator in Oracle Warehouse builder. When I mapped a table which has more than 7735 rows to another table.
I will get the error "ORA-06502: PL/SQL: numeric or value error: character string buffer too small".
How can I solve this problem?
Thanks a lot!

The problem is happening again.
When it happens, if I quit and I start again Oracle XE, the problem does not happen at first, but happens again after a while (the duration before the error is not always the same). If I increase the number of lines that are printed for the result of a request, I can induce the error; if I decrease the number of lines, the error is not happening.
Here is one of the request (that request returns about 5000 rows) that cause the error, and the complete error message:
