OWB and infomatica

Hi,
How do justify or rate OWB over infomatica?
Is it wise for me to use OWB in my business?
i need some good suggestion
Mani

Hi Mani
Boy you start with the big ones!
My two cents worth:
Like any software evaluation you need to match your needs with the functionality of the different offerings.
I think it safe to say that Informatica is a more mature product as is Ascential (now IBM) but OWB is catching up.
In our case we looked at our sources and had only three (3) different types: Oracle databases, SQL Server databases and flat files. I haven't written any maps against the SQL Server database yet but OWB has worked very well for me against the Oracle and flat file sources. The external table is especially nice for flat files and even though I have seen some comments against them, they have worked very well for me.
We compared what we needed and what it would cost to get the job done with each product and OWB won due to the functionality that we needed and the price. There is quite a difference in price.
From what I've heard Informatica is easier to use if you have a lot of data coming from the mainframe environment.
Good luck with your selection.

HS_FDS_TRACE_LEVEL=0
2. Add the following lines to listener.ora in Oracle server ($ORACLE_HOME\NETWORK\ADMIN)
(SID_DESC =
(SID_NAME = QA_DB2)
(ORACLE_HOME = $ORACLE_HOME)
(PROGRAM = hsodbc)
3. Add the following lines to tnsnames.ora in Oracle server ($ORACLE_HOME\NETWORK\ADMIN)
DB= (DESCRIPTION=

How to decide between OWB and ODI?

Having to decide whether to choose Oracle Data Integrator or Oracle Warehouse Builder like tool for creating a dataware house and loading data into it, what should I choose and why?
I'm an old pl/sql developer but new on datawarehousing (I've been dealing with it for few months) and I'd like to undestand what fits better for me. It seems to me that OWB and ODI look not very different to each other, don't they?
My Oracle vers. is 10gR2
Thanks!

Thanks!Oracle corporation's statement of direction says ODI is their strategic ETL tool and if you and investing into Oracle ETl for the 1st time then it is better to invest in ODI .
OWB will be supported and finally OWB and ODI will get merged into a single tool.
For a pl/sql guy like you , the code generated by OWB is easy to understand as OWB mainly generates pl/sql code ( apart from sql loader and sap abap code ) . But that should not deter you to use ODI as ODI generates mainly SQL code (plus sove native code depending upon the technology used and KM) .

OWB and Oracle Express or other methods...

Hi
Is it possible to connect Express DB directly from OWB and share some Objects
or import some structures via EIF-Files?
What's the best way to migrate from Express to "up-to-date" olap? We have little bit complicated structures with lot of permits (because of extern partners) and more hierarchies on dimesions (incl. time dimension) etc.
thanks
Jarek

Mike,
Simply speaking, Express can be considered complementary to OWB. OWB helps you create/maintain a relational star-schema warehouse. Express can then be used to analyze the information in that warehouse using it's inherent on-line analytical processing (OLAP) capabilities.

Build in OWB and make map in AWM?

Hi all,
Would it be possible to design and deploy the dimensional objects (dims/cubes) using OWB and make a mapping to populate them using AWM? These are all MOLAP objects. The advantage of designing in OWB is the editor and e.g. the ability to add calculated measures in cubes using the wizard.
Just did a quick test. When deploying a MOLAP dimension from OWB, in AWM it shows the map with several OWB-generated views to populate the object. I don't want to use those since I don't want to build a map in OWB. I have a simple 1-to-1 view to populate the object in AWM. However, when removing the OWB views from the map in AWM and replacing it by my view, when applying the changes it comes back with an error:
An error occurred creating DimensionMapGroup D_DIM_EMPLOYEE_M.TOTAL.MAPGROUP1.DIMENSIONMAPGROUP : ***Error Occured in DELETE_MAPPING_GROUP: You provided extra input starting at '$'.
The error detail window shows:
oracle.AWXML.AWException: An error occurred creating DimensionMapGroup D_DIM_EMPLOYEE_M.TOTAL.MAPGROUP1.DIMENSIONMAPGROUP : ***Error Occured in DELETE_MAPPING_GROUP: You provided extra input starting at '$'.

If this doesn't work it's just another blow to our olap-in-oracle implementation plan.
Does anybody have experience with this issue?
Thanks,
Ed

You'd better make the reservation of Genius Bar and show them about your problem.

OWB and OEM Version ERROR (Urgent)

Hi All,
I am using OracleWarehouse builder version 9.2.0.2.0.8 and OEM version 9.2.0.2.0.10 and i am getting error while creating cubes in OEM. Is it due to different versions of OWB and OEM.
Please Let me know, if anyone knows about it.
with regards
Mukesh Harjai

Hi Mukesh,
You do not need to create the dimensions in OEM, you can use Warehouse Builder to do this.
On how to do this, check out this viewlet: http://otn.oracle.com/products/warehouse/htdocs/OLAP_viewlet_swf.html, and perhaps take a look at the following whitepaper: http://otn.oracle.com/products/warehouse/pdf/Enabling_OLAP_with_OWB.pdf.
Thanks,
Mark.

OWB and AWM for loading DWH

Hello,
I am on the following version:
DB: Oracle 10.2.0.1 (both source DB and target DWH)
OWB : 10.2.0.1
AWM : 10.2.0.1
I have the following process:
From the source DB I use OWB to load relational dimensions (SCD 2). I use AWM to load data from these dimensional tables to a Analytic workspace. I use OWB because I need to track changes (SCD) and use AWM because OWB currently does not support Parent-Child dimensions where as AWM supports. I would love to load AW from OWB directly if it had parent-child support.
My question is:
All the load should be trigger-based, When my process (SQL) completes on the source table the OWB process of loading the relational dimension should start which is not a problem, I using the run_owb_code.sql for this. once the run_owb_code is complete, I want the AWM's maintain data process to start. I don't know how to do it. I tried saving the maintenance task to script and tried executing it, it doesn't seem to work. I don't want to AWM and run cube maintenance every time the cube needs to be refreshed.
Please note I don't have a cube in the relation world. My fact(cube) in the AW is a direct load from a table (as I don't need SCD here) so basically use OWB just to load the dimensions alone. AWM creates the actual cube with the dimension tables loaded using OWB and the fact table from source, So I don't think I can use the "dbms_awm.refresh_awcube(...".
Can somebody please help me in automating this load process
Thanks a lot in advance!
Maruthi

Hello,
I am sorry, after some research, I came across this post
Re: Cube and dimension refresh proactively
As per the above post, the script that is generated using AWM will work if the AW is not attached by any user.
I detached the AW and executed the script and the cube was populated with data.
Thanks,
Maruthi

OWB and BO

Hi,
We have Business Objects (BO) which uses legacy data warehouse in SQL Server.
Our new application is Oracle 10g(SE) based and has it's own BI Application. Vendor has supplied all the OWB Modules, repository, etc.
Eventually I would like to use BO as the BI application.
If the OWB is set for the complete ETL, can BO be linked directly to the Target database/data warehouse?
In this case do I require Dimensions and Cubes?
Since SE has limitations, I won't be able to create Dimensions/Cubes, so is there any possibility that I use only the Mapping and ETL functionality of OWB and ignore Dimensions and Cubes?

Yes, you can build your own layer as a BO galaxy and connect to the database directly. In some of our projects we only use OWB for ETL and database modelling and BO as frontend, because it is much better than the Oracle Discoverer.

OWB and Stage/Target Schema Options?

OWB and Stage/Target Schema Options?
=========================
Thanks for your replies.
As we know that we need to have Landing, Staging and Target (Data Warehouse) areas in ETL process. We are able to configure in multiple ways in OWB.
Option 1
Keep everything in single schema/oracle instance with different object naming convention.
Option 2
Keep each one in separate schema such as Landing schema, Staging schema and Target schema in single oracle instance.
Option 3
Keep each one in separate server such as Landing server, Staging server and Target server in multiple server/oracle instance.
What are the advantages/disadvantages on above options?
Which of the above options worked better in OWB environment for you?
There are some folks suggests to work with out staging schema. Is it a good idea?
Do you have any pointer?
Thanks in helping out.

Option 1
Best for small Project .Some 15-10 Target tables.
Difficult to manage and Recovery will be difficult
Small team Managing Everything
Option 2
Best for Big project having lots for tables .
Easy to manage.
Option 3
NA

Comparison between OWB and PL/SQL development

Hello,
I am preparaing a presentation comapring development in OWB and development in PL/SQL.
Can anybody know the time saved by using OWB (ratio, percentage...) ?
Thanks in advance,

Hi,
1) OWB is simple to use.
2) we need not know the internal logic of PL/SQL to work on OWB.
3) All the cursors will be created automatically and nothing needs to be mentioned.
4) The GUI is very easy to operate and adding conditions are very simple.
5) The loading properties can be set easily and we know how the mapping will behave.
All said above are the advantages of OWB, but OWB is only a tool and a TOOL will always have its limitations.PL/SQL is a kind of programming language with which we can do anything and everything but in OWB we cannot make everything possible.

OWB and Windows 7

Hi, we're trying to get OWB running under Windows 7. Right now, we're constrained on staying with OWB 10.2.0.4 (or possibly 10.2.0.5 if upgrade is needed). Anyone had luck getting this to run? Maybe by using the special Vista version or something?
p.s. Oracle support says OWB 10.2.xxx will not (ever) be supported on Windows 7 - but we've got to try something....
I'd try this out myself - but I don't have access to Windows 7, it's on a production control person's machine we need to get this working.
Thx,
Scott

I'm running 64 bit Windows 7 and OWB 11gR1.
OWB 11g won't work properly when installed natively - there are far too many places where exceptions are trapped and ignored - hiding errors.
OWB works fine when installed in a 32bit XP VM.
If you are on Windows 7 Business or Ultimate, you can install Windows Virtual PC and XP mode.
Install in a VM and it works fine. Windows 7 actually has some nice integration features to make this layering of Operating Systems a little more transparent.
I think the problems relate to the 64 bit java vs the 32 bit java and the crappy exception handling that went into OWB.
A well written java program (see SQL Developer) shouldn't have too much difficulty in the port to 64 bit.
I'd wager that OWB will never make it to 64 bit. Some form of the future merged OWB and ODI will make it's way to 64 bit Windows.

OWB and Workflow

I'm running OWB 10g on a 10g database. I'm attempting to deploy the workflow process developed in OWB to the edw schema in my database. I'm receiving the following error.
RPE-02018: Oracle Workflow schema OWF_MGR on host 10.150.10.20 cannot be accessed using service DWREP through port 1599. Please check the location details and try again.
- ORA-01017: invalid username/password; logon denied
Do I need to deploy the processflows into a schema that has runtime objects? I tried to deploy the flows to owf_mgr's schema and got a runtime repository does not exsist. Then I tried to deploy the flows to my edw schema which has my target dims and cubes, and I receieved the error mentioned. Any assistance would be greatly appreciated.

Ray,
You create a process flow module, and a process flow location (stating OWF type and version 2.6.3). Then you register this location to the OWF_MGR schema in the deployment manager.
Please verify you have the setup as described here.
Then you click deploy and OWB will create:
- A dblink to the Runtime Repository
- A workflow definition in the OWF_MGR schema with the correct activities.

Upgrade to 10.1.0.4 owb and 10grl2 db - mapping fail

Hi,
Have recently upgraded owb from 10.1.02 to 10.1.0.4 and db from 9.2 to 10.2 and now am getting a mapping failing with ORA-00972: identifier is too long. The sql in the cursor being generated is failing, have tried to reduce operator field names but with no luck. Any ideas ????
Cheers,
Brandon

I had the same problem.
The problem is related the length of the database link
for one of the test data tables.
You have, for that test data, to use the button that creates a
new database link, use a shorter name and use it.
