Hi Mark,
I exited from OWB 10g and tried again and it worked fine.
CONCLUSION:
If I am working continuously then owb10g works fine. If during owb10g connection to oracle10g, I don't keep the system busy, then the OWB10 to Oracle10g database connection automatically dropped or hanged. But when I exit, and start the OWB 10g again, it work fine.
This has happened many times. May be my system problem (oracle and owb configuration).
You may try connecting owb10g to oracle10g and keep the system in rest for half to one hour. In my situation, the database connection drop. Please let me know if there is some additional configuration required which will configure the system so that it should not drop the DB connection if the system is on rest.
Waiting for your kind response.
Thanks
Munir

OWB 904 - problems creating time dimension

I'm using Oracle9iR2 DB and OWB 904. I have not much experience with OWB 904 yet and problems with creating the time dimension.
I tried to figure out the example which comes with OWB 904 and did everything as it is written in the readme.txt file:
1. loaded the time table functions owb_time_seq.sql and owb_time.sql in my runtime user schema
2. imported the owb_bp_time.mdl file into my design repository, which created the demo project 'OWB_BP'
The problems which I have with this demo are:
1.) I get warnings when I validate the mappings (TF_TIME_MAP):
VLD-1002: Mapping object T_TIME is not bound to a repository object.
VLD-1004: Column length of L_DAY_NAME is longer than the target column length.
VLD-1004: Column length of L_MONTH_NAME is longer than the target column length.
VLD-1004: Column length of L_QUARTER_NAME is longer than the target column length.
VLD-1004: Column length of L_YEAR_NAME is longer than the target column length.
VLD-3260: No Output Attribute name is specified. In this case, the attribute’s physical name will be used.
VLD-1123: Missing location information for Module WAREHOUSE.
VLD-1115: Commit frequency is defaulted to Bulk Size.
I know how to solve the errors VLD-1002, VLD-1004, VLD-1123 and VLD-1115 but I have no idea how I should solve VLD-3260 and VLD-1002, because reconcile outbound is not possible for the T_TIME dimension.
2.) When I try to import the table function
TIMEDATA (IN VARCHAR2, IN NUMBER) return TABLE
from the runtime user schema into my design repository I get the error message: Argument Data type is not supported.
3.) I cant deploy the mapping TF_TIME_MAP.
Is it possible to use the table function from the demo to create a time dimension and to import it into my own project? My aim is to create a bean compliant time dimension and I want to know what I have to bear in mind to accomplish that. The OWB904UsersGuide didn't give me enough information, therefore I'm asking if you can help me out.
Thanks in advance,
Dirk

Dirk,
The way you should approach the time dimension is following:
- Run the SQL scripts into your target schema (you already did).
- Import the MDL file (you already did).
- Copy and paste the times dimension into your own project to be able to use it.
- Copy and paste the mapping you want to use to your own project.
- If necessary, modify the times dimension according to your needs; change the mapping accordingly.
- Open the mapping, do a right mouse click on the time dimension and select 'Reconcile inbound'. Select matching strategy to match by bound name.
We do not currently support the table function as an object in the metadata repository. I.e. if it exists at runtime then you can call it (as the time dimension load mappings do).
With the objects in the target schema you should be able to deploy the mapping.
Thanks,
Mark.

OWB BROWSER PROBLEM

I am new with owb and have a problem with that Warehouse Builder Browser.
At the first I start the OWB Browser Listener. That's ok.
Afterwards I start the Repository Browser. That's ok.
After short time a Browser window open with the login PAGE at the Control Center.
After input of the necessary data I come on the report PAGE.
Now the problem: after I click Design Repository: Navigator
I come back again on the login PAGE. With the others links the same happens (such as Object Summary Report)
What is the problem??
I use Oracle 10gR2 and Warehouse Builder 10gR2
Please help me.
Thank you for answers

Don't you have to enable session cookies in order to IE to work?
I don't know, this is just a guess.

OWB Installation problem on AIX 5.2

Hi,
We are trying to install OWB 9.2.0.2.8 on IBM AIX 5.2 using the download version from OTN. Following installation instructions, we have removed all references to existing ORACLE_HOME in the environment variables: CLASSPATH, PATH, LIBPATH and LD_LIBRARY_PATH.
When we try to run installer from owb92aix/Disk1/runInstaller
following error message appears: Can't find libjvm.a
and the installation aborts.
Any help is appreciated.
Thanks,
Aravind

Yes, we do have the java virtual machine installed in /usr/java131/jre/bin and it is referenced in PATH variable.
When we extracted the downloaded tar file for AIX, the file libjvm.a exists in the extracted directory. We do not know why the installer is unable to find it.
Thanks,
Aravind

OWB 11g Problem in running Process flow

I’ve build a process flow as described in “Getting Started with Oracle Warehouse Builder 11g”. But if I run the process flow I get a warning message “You have to deploy this object before running” followed by the error RTC-5170: The selected objects do not require deployment as they are all up to date in the Control Center.
Therefore I’m not able to run the process flow. What’s wrong? It looks so easy in Getting Started but it doesn’t work.
I’ve found two threads regarding this error from last year in this forum. But there is no solution for OWB 11g.
Has anyone an advice for me?

I've successfully installed OWF as described in Installation guide (all components are on the sam server).
But when I deploy a workflow in OWB I get some errors. In the job details
I find ORA-00942 and RPE-02053. It seems that the workflow repository is missing.
Are there additional steps for creating a workflow repository?
Or what is wrong? All installation logs (wf.log and workflow.log) are without errors and with success messages.
Any idea?

OWB Install Problem on NT Workstation

We are trying to install the new OWB on Dell Laptops running NT4 SP6a (256 meg RAM). After the Reports Runtime install, the Enterprise 8i install runs for about 15 mins and then just disappears with no errors. We haven't found any logs with any obvious errors noted, except one time we got an error updating the registry.(We're logged in as the NT admin.
The server install went fine, and a desktop workstation using only the 8i client (no local database) also went fine.
Has anybody else run into anything like this?
Thanks
Ron

This is a linux discussion thread.
But, I would like to see what the "bare essentials" (listener.ora; tnsnames.ora; and other filez NEEDED) for oracle8i/webDB to co-exist on my redHat 6.1 distro. My install goes fine. Its the post install steps that seem to be documented differently everywhere I search!

OWB Instalation Problem

Hi,
I am trying to install OWB on a WindowsXP machine.
When i click on the setup cmd prompt pops up but go's no further.
The installation doesn' start.

There's another setup.exe in the directory /install. Maybe you also need to start access_setup.bat before you start that setup.exe.

OWB Scripting Problem

When trying to OMBRETRIEVE MAPPING i get an error stating MAPPING is not a valid type.
The OWB repos is 9.0.3 It is the old schema/ applicaition setup. Is this a bug with the scripting on this version? is the syntax different? I am using the newer scripting reference.
Is there a patch to fix this? Or is moving to 9.4 the only option to fix the scripting ?
I have a repository that is around 2 years old. I need to remove the default hinting on all mappings. We are about to turn on parallel query in the database.
So if scripting does not work. And upgrading is the long term option. Can i get a suggested hack. What metatable would i Need to update to set the operators loading hint and extraction hint to null?
Regards,
Richard H.

Yes I set the context to project and application module. It is an older OWB repos. Where by you need to OMBCC APPLICATION <MODULE_NAME>
When I attempt to action OMBRETRIEVE MAPPING <name> GET OPERATORS I get unknown action type error for Mapping.

Richard.

OWB Deployment problem on UNIX

Hi all
We are facing problem while deploying object of a mapping on UNIX.
Validation and Generation of the mapping is working fine, but while deploying, it just shows the progress bar with 0% and stops. Its not generating any error message also.
The mapping was developed on the windows environment and imported to UNIX environment. After imported it was successfully validated. The DB link was also tested successfully.
If we deploy the same mapping on windows its working fine.
Please let us know what could be wrong, since the mapping needs to go live on Monday.

Please immediately go to your backup plan.
I have been in situations like this, and you need to move to plan B at once.

Donna

OWB 9.0.3.37 and imported plsql packages

I have some problems in owb version 9.0.3.37 with imported packages.
I can't delete a procedure/function in the imported package,in the package body I can do this .
The only way do delete procedure/function is do delete the package and re-import it from the db into OWB.
Problem then is that when I valid a mapping I must reconcile inbound the transformation (link broken).
Is there not another way to do delete function/procedure from a imported package.
Is the import of packages in the new version 9.2 still possible?

Hi,
There is an internal reason (validation) why we cannot allow you to delete functions from a package that you imported. That model is still the same in the latest production release.
Thanks,
Mark.

How do we find if any changes in a table

Hi All,
We have created some tables in an user. when ever we create any table that table name or object name stored in All_objects like that.
if we see that table (all_objects). we can find when table has created and when last DDL performed on respective tables.
i would like to know when table has created (when DDL performed )
along with when DDL performed on that table like
1> one day i can drop constraints.
2> one day i can desiable/enable constarints.
3> one day i can add/change column name/ data type or null to not null.
4> one day i drop some columns
i wanted to know when i have created table and when i changed any above mentioned cases. where can we track historical or at least latest changed.
Regards,
venkat

Suppose if I create any triggers. It won’t create any problem in database but we are using ORACLE WAREHOUSE BUILDER (OWB 10gr2) for extract, transform and loading. I am sure about OWB creates problem for data extract, transform and loading.
What to do? Do you have any way to find out? Well, triggers do obviously have a small impact on performance, but that will depend on exactly what you are doing and how much you're doing it.
How it effects OWB I don't know. The only time I ever used OWB was when evaluating ETL tools and came to the conclusion that it was a) a complete P.I.T.A. to install as the documentation led us all over the place and b) it was only any good at loading data into Oracle, not at getting data out again (certainly not as XML anyway).

SCD issue

Hi,
I am implementing a Slow changing dimension with a parent-child hierarchy using OWB 10.2.0.2.
My data is like this:
Prod Parent_prod
P11 P1
P12 P1
P21 P2
P22 P2
P211 P21
P211 A21
A21 A2
I have to monitor changes tot he Parent say for example
A21 A2 can change to
A21 P2
Then I have to expire the row A21 A2 and make A21 P2 effective.
In OWB, I have implemented this as a Type dimension. With 'Prod' as the Business key and 'Parent_prod' to trigger changes.
This does not work properly. Here if I execute the mapping without any changes (A21 A2 still remains as A21 A2), I get an worning message "unable to fetch a stable set of rows from source" and in the table it has expired both
P211 P21
P211 A21
and created 2 separate rows with the same value. So basically it inserted 2 rows expiring two rows. This way whenever I load if there are no changes for these rows these rows will still be inserted and the tables keeps expanding.
How can I solve this issue? Any ideas please
Thanks a lot in adavnce!

You will still need something else as your business key in this instance, which is OWB's problem in determining a stable historical set.
A case in point:
e.g. First time you read the source table you have two rows:
Prod Parent
A1 A21
A1 A22
So you create the two rows.
Now, at your next refresh the source table contains:
Prod Parent
A1 A91
A1 A92
How is OWB to determine if A1/A21 changed to A1/A91 and A1/A22 changed to A1/A92? Or if A1/A21 changed to A1/A92 and A1/A22 changed to A1/A91?
You will need to find some other attribute or method to determine exactly how these relationships change over time in order to ensure that you are correctly creating your SCD.

Exporting definition of the external file - please help.

Hello to all of you wonderful people.
either me or my machine are just about to jump out of the window here..
I have imported external file into OWB - no problem at all - everything singing and dancing.
I now need to export this file and 'tweak' it a bit, rename and reimport - to save typing gazillion column names for other files i have to import.
It was possible to do so in OWB 9i, however, everytime i am trying to do it i get this error message:
Warning: MDL1427: Cannot export selected PROJECT <ADMIN> because it does not exist in target repository.
Firstly,Of cause it is not in target repository - it is an external file! once i load my target table with it,it will be in target repository.
secondly, I DO NOT HAVE A PROJECT CALLED <ADMIN>...
Googled it and searched oracle, technet etc - to no avail. found only one entry for it on this amazing forum... but no solution :(
Dearest Tom OWB it was your post about a month ago - did you manage to find out what that mean and how to go about it?
Any help/hints would be greatly appreciated.
Thank you very much for all your help and support regarding this issue.
Kind Regards
Vix

Now I remember!
There are two different ways to export the metadata. Clicking a project or object name less options and for me the error above.
However if I click on the project and go to the top menu and to Design > Export > Warehouse Builder Metadata I am able to export the metadata fine. You also get access to the advanced tab this way.
Bit strange but awell.
Cheers,
James

Problem in OWB map for source change capture

The problem is as follows:-
Our OWB map between two different databases, captures change in data at source and populates them in target. It is a one to one map. The map is failing to process some rows from source database though it gives no:of errors as 0 in the audit view thus we infer that the map is running successfully.
In our case, we have a composite key ( Instance_id, Version_number) at source as well as target. One instance_id can has more than one version number. We have observed that the view is picking up all the version_number for a particular instance_id but the map is unable to populate the last version_number to the target table.
But when this map was executed in another environment and it is successfully populating all the data in the target.
The brief description of the map is as follows:-
The map has a view which captures all the changes in data (insert and update) .From this view we filter the rows which were already processed in previous map run (with help of watermark). Then we sort the rows based on DML type and watermark . These rows are then mapped to a target table. The loading type of the map is INSERT/UPDATE.
