OWB 10g Help

Hello,
I am a newbie. I just installed OWB 10g release 2. What are the default login credential? I have tried all system/manager and stuff???
Do we need to install the database separately? If so will oracle 8i support it?
Thanks

Hi user621787
Please consult the following links in order to get all the information related to the OWB :
http://www.oracle.com/technology/products/warehouse/index.html
http://www.oracle.com/technology/products/warehouse/htdocs/OWB_10g_faq.htm
http://www.oracle.com/technology/documentation/warehouse.html
On your second question the answer is yes:
What versions of Oracle database can I use with Warehouse Builder 10g?
For the target database, users can use Oracle 8.1.7, 9.2 and 10g with Warehouse Builder 10g. As a source, Warehouse Builder 10g supports:
* 7.3.4 or higher if your target is a 8.1.7 database
* 8.0 or higher if your target is a 9.2 database
* 8.1.7.4 or higher if your target is a 10g database

OWB 10g Release 2 from 32 bit to 64 bit on Linux

Hi guys,
I have a client who is planning to migrate their Linux server from 32 bit to 64 bit and migrate their Oracle database from 10.2.0.3 from 32 bit server to 10.2.0.3 from 64 bit server.
We have OWB 10g Release 2 (10.2.0.3) installed in the 32 bit server.
Our DBA is planning to move the entire database to the new server including the OWB repositories.
My question is,
Will the following work?
1. Install the OWB 10g Release 2 (10.2.0.3 or 10.2.0.4) 64 bit in the new 64 bit Linux 64 bit server
2. Remove all the OWB repository user schemas & roles from the database where OWB is installed
3. Install the OWB repository in the new 64 bit server
4. Import the .mdl backup of the project from existing OWB 32 bit to the new OWB 64 bit server
5. Configure the project with the new server
OR
Since our DBA is planning to move the entire database to the new server including the OWB repositories
1. Install the OWB 10g Release 2 (10.2.0.3) 64 bit in the new 64 bit Linux 64 bit server
Will I be able to access my repository that is migrated from the 32 bit server (avoiding the installation of OWB repository and importing the project and configuring the whole project in the new server) ?
Please someone shed some light on this. Your help is appreciated
Thanks in advance....

Does this mean, ... we have to install the OWB 64 bit and install a new repository in the 64 bit server?In my opinion you don't need to create new repository.
After migrating database to 64bit perform steps from Metalink note 434272.1 "How To Update Warehouse Builder 10.2 After A Database Cloning".
It is better to save the same path for new OWB 64bit software. If you install OWB into different path you need to update OWBRTPS table with new path to OWB software (look at metalink note 550271.1).

SCD type 2 in OWB 10g R2

Hello,
I am trying out the SCD type 2 in OWB 10g R2. I have no hierarchies and hence created a dimension with one level. Apart from three business attributes I have 2 mandatory attributes as "EFFECTIVE_DATE" and "EXPIRY_DATE". I have set one of the business attributes to "Trigger History".
I have 3000 rows in the source table. There is no transformation. the data is loaded from source to this dimension directly. One business attribute is loaded using a constant.
When I executed the mapping, all 3000 rows are populated in the target with the expiry date column having null values and current date in the effective date, which is absolutely fine. When I execute the mapping again without changing anything in the source, rows are inserted in to the target with the effective date set to the second run and the expiry date set to previous effective date. As I understand new rows should be inserted only if there is change in the data.
Please correct me if I am wrong. Please clarify and if my understanding is right where am I doing wrong with OWB?
Your help is greatly appreciated
Thanks a lot on advance!
Regards,
Maruthi

Hi Roelant,
I think it is important to be aware that although Paris - 10gR2 - is not actually buggy (in this respect!), it is really quite idiosyncratic in exactly how it processes SCDs.
I followed up on your and Mark's comments, and did an in depth analysis of this topic. It is at http://www.donnapkelly.pwp.blueyonder.co.uk/documents/OWB_10gR2_SCD.pdf
My conclusions are perhaps of interest to anyone considering doing SCD processing with Paris.
I'll be doing a follow-up this weekend, and publishing a sort of 'how-to-do-it' guide.
Cheers,
Donna

OWB 10g -- Can't Create Database Links for Data Source and Target

We installed OWB 10g server components on a Unix box running Oracle 10g (R2) database. The Designer Repository is in one instance. The Runtime Repository and the Target are in another instance. The OWB client component was installed on Windows XP. We create a data source module and a target module in OWB. The data source is on another Unix box running Oracle 9i (R2) database. We try to create database links for data source module and target module, respective. But when we created and tested the DB links, the DB links were failed.
For the database link of data source, we got the following error message:
Testing...
Failed.
SQL Exception
Repository Error:SQL Exception..
Class Name: CacheMediator.
Method Name: getDDEntryFromDB.
Repository Error Message: ORA-12170: TNS:Connect timeout occurred
For the database link of target , we got the following error message:
Testing...
Failed.
API2215: Cannot create database link. Please contact Oracle Support with the stack trace and the details on how to reproduce it.
Repository Error:SQL Exception..
Class Name: oracle.wh.ui.integrator.common.RepositoryUtils.
Method Name: createDBLink(String, String, String, String).
Method Name: -1.
Repository Error Message: java.sql.SQLException: ORA-00933: SQL command not properly ended.
However, we could connect to the two databases (data source and target) using the OWBs utility SQL Plus.
Please help us to solve this problem. Thank you.

As I said prior the database link creation should work from within the OWB client (also in 10).
Regarding your issue when deploying, have you registered your target locations in the deployment manager and did you first deployed your target location's connector which points out to your source?
I myself had some problems with database link creations in the past and I can't remember exactly what they were but it had something to do with
- the use of abnormal characters in the database link name
- long domain name used in as names.default_domain in my sqlnet.ora file
What you can do is check the actual script created when deploying the database link so see if there's something strange and check if executing the created script manually works or not.

RPE-01012 error in OWB 10g

Hi,
I am trying to deploy a simple mapping with both source and target definitions as relational(Oracle) tables and it is failing throwing the following error.
RPE-01012: Cannot deploy to the target location because it is owned by a different runtime platform.
But I am able to deploy mappings successfully when the source is a flat file and target being a relational table. I am having problem only when both the source and target are relational. I am using Oracle 10g and OWB 10g. Any help would be appreciated.
Thanks in advance,
Sri

Good morning Sri,
Does this problem occur in the same module or in different ones?
If in different ones, maybe one of your locations has not been correctly registered?
Cheers, Patrick

ODBC Connectivity in OWB 10g

Hi,
I have one of my data source as AS400. I have setup a DSN to connect to this data source. I want to know how I can connect using OWB 10g to the AS400 data source using this DSN.
Is there any other way that I could connect to the AS400 data source using OWB 10g without using any additional drivers which involve a cost :-) ?
Thanks for your help in advance.
Thanks & Regards,
Harshad Borgaonkar

Hi Harshad,
You can do this with the heterogeneous services.
http://www.datadirect.com/developer/odbc/oracle_heterogeneous/index.ssp
has a good description of what to do.
You'll have to setup the heterogeneous service on an Oracle database on the same platform for which you have ODBC drivers for, presumably Windows.
You should then be able to connect to this database in OWB and create a connection under Databases -> Other -> ODBC or Other.
Cheers,
Colin

Hi
As mentioned by Andreas you must not have the ORACLE_HOME environment variable set when you are doing this work. You also need to make sure that you don't have any Oracle software running, that all services (if on Windows) are shut down, and that you don't have any other environment variables that Oracle would use. Thus you probably shouldn't have CLASSPATH, PERL5LIB or QTJAVA set. What I do is rename these to ORACLE_HOME1, CLASSPATH1, PERL5LIB1 and QTJAVA1.
The final thing I do is to alter my Path to remove all references to existing Oracle software. I save my existing path first though so that I can put it back later (funny how a backup comes in handy at times). Then after the install I look to see what path settings OWB added and I insert these into my original path, reinstating any environment variables that have not been replaced by OWB.
I got to tell you that I find it a pain in the neck that some Oracle software won't install when they detect another Oracle product on the same machine. When you think about it, how head shakingly, frustrating is that in the modern world? Personally I, and my clients, are crying out to see these elementary interactions overcome once and for all.
Things are certainly improving but boy its exasperating when one product interferes with another from the same vendor.
Does this help?
Regards
Michael

OWB 10g R1 - Walk thro practice?

Hi,
I am very new in OWB. As my starting practice, I would like to have a walk thro to create a complete sample project with OWB 10g R1 on Oracle database 9.2.
I found some links on Oracle site for downloading; but not sure which one can be my starting point. I would appreciate to let me know the one (link) that found it useful for to start.
Thanks

Look at Oracle by Example at

OWB 9.0.3 migration to OWB 10G R2

Hi All,
I am in the process of doing the Migration of OWB 9.0.3 migration to OWB 10G R2, I am doing it for the first time.
is there any manual or can any one help me with the steps to achieve the migration.
thanks.

Hi there. I am currently going from 9.03 to 10.1.0.5.
You cant go 9.03 to 10.2.03 (paris or 11G) the leap is too large. However you can go straight from 9.03 to 10.1.0.5.
I exported 9.03 mdl's and imported them into 10.1.0.5 the mdl updater kicked in and upgraded the 9.03 mdls which i then imported into 10.1.0.5.
then after adjusting the repos to use the locations (they dont exist in 9.03). register the locations in the runtimes etc. then you can generate and deploy and it all should work just fine.
Now I am unable to go straight to 10.2 (due to the testing i have to complete) but I did test the mdl files that were created by the upgrade process from 9.03 to get into 10.1 and they in turn can be imported upgraded into 10.2 so you can hop versions if it makes sense for you.
It does involve some setup. I tend to export import OWB when doing upgrades. So installing seperate OWB repositories is what I do (as in owb design repos 9.03 in one database instance and 10.1 in another ) that way you dont break /loose your 9.03.
if you can clone your target 9.03 target runtime database and simply use the target installer in 10.1 to install the 10.1 runtime into your current target schema's. plus you can do some parallel testing. Be prepared 9.03 is faster than 10.xx its runtime engine is simply faster. there is overhead in all the extra runtime logging.
Plus the way you release code will most likely change (ok it has too) you cant run/release/deploy 10.xx maps without using the OWB deployment framework either UI or scripting via OMB Plus.
Have Fun
Richard.

Owb 10g R2

I’m new to owb and I’m using owb 10g R2. I need to create a map to return a set of values based on the latest process’s date.
The map reads data from a view source and then using sorter operation to sort data by ORDER_NUMBER, DATE_PROCESS, ORDER_STATUS asc
ORDER_NUMBER     DATE_PROCESS     ORDER_STATUS
A00378091          06/23/2011               1
A00378091          06/25/2011               3
A00378091          07/15/2011               5
A00447816          05/17/2011               3
A00447816          05/20/2011               5
A00447816          06/25/2011               4
I use the aggregator group by order_number to get the max(date_process) but I don’t know how to get a value of order_status.
How do I crate a map to return the value as
A00378091          07/15/2011               5
A00447816          06/25/2011               4
I very appreciate your help, thanks.

Thanks Igor. I still don’t know how to do it. I’m sorry that I’m not clear that the set of data are not in a table yet.
The following is a list of steps in the map.
1. Read data from view (~ 900,000 rows)
2. Sort data using sorter operation.
Sorter operation ORDER_NUMBER, DATE_PROCESS, ORDER_STATUS asc (data are not in a table)
A00378091      06/23/2011      1
A00378091      06/25/2011      3
A00378091      07/15/2011      5
A00447816      05/17/2011      3
A00447816      05/20/2011      5
A00447816      06/25/2011      4
3. Aggregator group by order_number to get the max(date_process). I don’t know what expression on mrp_order_status to get the latest value based on max(date_process). I can’t use min/max(order_status) because it gave me a wrong order_status’s value
4. table (loading type Update/Insert)
order_number is a key on a table and I need to get the latest data of date_process and order_status from the sorter (or aggregator) to update/insert into a table. So the data in a table will contain
A00378091      07/15/2011      5
A00447816      06/25/2011      4
I never use table operator, I try to find the site so I can learn more about it. Would you please explain step by step? I very appreciate your help.

How do we learn more about expert in OWB 10g?

How do we learn more about expert in OWB 10g?
We are using OWB repository 10.2.0.1.0 and OWB client 10.2.0.1.31. The Oracle version is 10 G (10.2.0.3.0). OWB is installed on Linux.
I reviewed user guide. It have little info on expert of OWB 10g.
I like to know/learn more about it.
Do we have cookbook type of docs?
How did our forum members learn about owb 10g expert?
Thanks in advance.
RI

Here are various bits and pieces that should get you started, I'll see if there is a cookbook, I know we have an internal one.
There is an introduction paper here;
http://www.oracle.com/technology/products/warehouse/pdf/Oracle%20Warehouse%20Builder%2010gR2%20What%20is%20an%20Expert.pdf
There are examples on the utility exchange, probably a reasonable one that uses the built in components is the data mover expert;
http://www.oracle.com/technology/products/warehouse/htdocs/Experts/datamover.zip
There are other interesting examples, such as the create dimension from expert that helps building a dimensional structure and maps. For this one I added simple java procedures for a shuttle dialog and a data entry table that allow different information to be captured.
See the create dimension from expert here;
http://www.oracle.com/technology/products/warehouse/htdocs/Experts/datamover.zip
Another example on accelerating map construction is the SQL to map accelerator which uses the OWB custom dialog to get information, and can be found at the blog post http://blogs.oracle.com/warehousebuilder/newsItems/viewFullItem$198
You can edit these experts and see the code, the data mover expert has much less code and just glues together pieces of the OWB UI components into a task list that is more specific for the user. The create dimension expert is much more tcl oriented but really simplifies the task at hand.
Cheers

I am using OWB 10g release 2 but there is no feature for version control. The snapshot feature and export/import can help but Its very difficult with big project.
Is there any new feature with OWB 11g release 1 or 2 for version control ? Do you have any proposition for version control in 10g ?

Hi Robin,
In the repository there can be only one version at the moment. If you have to work on an older release, you have to load it into another repository.
We proceed as follows:
1. Build a collection containing all objects that belong to the release
2. Export that collection
3. Check the file into CVS
4. Import the file into production repository (in production db)
5. Deploy from the production repository to the production target schema
That way the release that is currently deployed on production is also in the production repository. You may do hotfixes directly here or just have a look at what is currently deployed.
In our development repository we can work on new features.
I gave a talk about automating this process on DOAG 2008. You may request the presentation here [http://www.metafinanz.de/leistungen/leistungsbereiche/bi-reporting/data-warehousing/kontaktformular/|http://www.metafinanz.de/leistungen/leistungsbereiche/bi-reporting/data-warehousing/kontaktformular/]
Though the slides are in german they show the architecture and should give you some idea.

Carsten.

OWB 10g - The time taken for data load is too high

I am loading data on the test datawarehouse server. The time taken for loading data is very high. The size of data is around 7 GB (size of flat files on the OS).
The time it takes to load the same amount of data on the production server from the staging area to the presentation area(datawarehouse) is close to 8 hours maximum.
But, in the test environment the time taken to execute one mapping (containing 300,000 records)is itself 8 hours.
The version of Oracle database on both the test and production servers is the same i.e., Oracle 9i.
The configuration of the production server is : 4 Pentium III processors (2.7 GHz each), 2 GB RAM, Windows 2000 Advanced Server, 8 kilobyte primary memory cache, 512 kilobyte secondary memory cache, 440.05 Gigabytes Usable Hard Drive Capacity, 73.06 Gigabytes Hard Drive Free Space
The configuration of the test server is : 4 Pentium III processors (2.4 GHz each), 1 GB RAM, Windows 2000 Advanced Server, 8 kilobyte primary memory cache,
512 kilobyte secondary memory cache, 144.96 Gigabytes Usable Hard Drive Capacity, 5.22 Gigabytes Hard Drive Free Space.
Can you guys please help me to detect the the possible causes of such erratic behaviour of the OWB 10g Tool.
Thanks & Best Regards,

Hello Harshad,
2 GB of RAM doesn't seem to be very much to me. I guess your bottleneck is I/O. You've got to investigate this (keep an eye on long running processes). You didn't say very much about your target database design. Do you have a lot of indexes on the target tables and if so have you tried to drop them before loading? Do your OWB mappings require a lot of lookups (then apropriate indexes on the lookup table are very useful)? Do you use external tables? Are you talking about loading dimension or fact tables or both? You've got to supply some more information so that we can help you better.
Regards,
Jörg
