To find project-mapping relationship in OWB design repository.

In a application aI am firing query on the design repositoryy schema.Here I want to find all mappings coming under a particular project.For example I got a table called ALL_IV_XFORM_MAPS to take the map names and ALL_IV_PROJECTS to take the project names.But I couldnot find out any table corresponding both project name and map name.Please help.
Thanks.

I don't have access to a repository at the moment, but you will have to link the map to the module it is in, and that module will belong to a project.
Isn't there something like 'ALL_IV_MODULES' ??
Hope this helps,

OWB Design Repository Tables

Hi All,
Is there any document from where I can get a decent insight into the OWB design repository tables and their functions.
Being a bit more specific, while working in OWB 10gR1 I have experienced situations where a mapping suddenly shows a null pointer exception and becomes un-editable, and un-deployable and un-executable. The only solution then is to make the mapping from scratch. If I can know which all design repository tables are involved in storing a mapping information, then perhaps I can go to the backend fix the issue and retrieve the mapping.
Please let me know if any of you have any infomation regarding this.

Thanks a lot for your information. It gives me some idea of the tables from which these read only views are created.
I hope, in order to understand more what these underlying tables are for, I need to scratch my head :))

One schema for OWB Design repository, runtime repository and target schema

Currently we have contents of OWB Design schema, runtime schema and target schema all combined into one schema of the same database in OWB 9.0.2 as well as OWB3i. We like to move to OWB10g in very near future. Can we keep the same structure for convenience of migration in OWB10g? Is it mandatory that OWB design repository (and components) must be separate from OWB run time repository (and components) and target schema? In other words is it possible and workable to use only one schema to contain OWB design repository, OWB run time repository and target schema in OWB10g environment with repositories to be situated on Oracle v9.2.0.1.0? Also what special considerations should be taken to create the database v9.2.0.1.0 and installation of OWB10g. What are the problems/side-effects to have all in one schema?
Also please let me know how to install Oracle Workflow server to be used along with OWB. Will OWB10g work with repository on Oracle database v9.2.0.1.0?
Your prompt advice will be very well appreciated.

The design repo is a metadata repo that stores all the design-time objects and so forth.
It is an architectural decision that you or your team need to decide on. There are many flexible ways to architect an OWB infrastructure.
Also, your repository users will be using the design repository on the the other DB instance to do their design work...potentially less people always hitting the target database all the time.

Owb design repository

I am unable to log in OWB Design Browser for report generation on Design Repository. I am in a Oracle client machine as well as it is OWB client. It giving an error message, 'Invalid Oracle HTTP Server information' whenever I am trying to login OWB design browser.
I am providing ip address of my oracle database server i.e host machine, port no, user id. What could be the reason and what is the solution?
And also I want to know the exact data for all these three columns.

One schema for OWB Design repository, runtime repository

Can we use only one schema for the design and runtime repositories on the same database instance and leave the target schemas separate? What are the advantages and disadvantages of this approach?
Thanks a lot for your time and reply.

Hello beatbisig
You got it right. Starting from OWB10gR2, the two types of repositories have been merged in to one. So if you have your design work hosted on one database, but want to keep the production database off-limits from developers you deploy from your design repository to the production repository. If you then connect to the production repository using the Design Center you wouldn't see any mappings there.
Why this wasn't done in the first place, even using the Oracle Designer repository I never understood ...

Defining roles and access for OWB Designer

Hi,
Can i Define roles and access rights to different on 1 OWB Designer repository?
I want to send my mappings for code review but i dont want them to log into the OWB designer with write access.
How can i achieve this in the same OWB designer repository as the one i am using?
I am using OWB 10.1.
I found some table - WMP_USER_ROLES,WMP_GROUP_ROLES,WMP_GROUP_REPOSITORIES
when i logged into the designer schema through sqlplus
Thanks
Sagar

Hi Sagar,
Yes you can do that. Basically you can create a db user, and then register the user with a repository. By default that user has all privileges, however it now is audited per user as to what he/she did. How to do this look at the doc (find SecurityHelper)
To enable you to protect metadata there are a couple of strategies (implemented via a simple PL/SQL API). For an example (this one works with policies on the module level) take a look here (http://www.oracle.com/technology/sample_code/products/warehouse/files/Dev_Status_Policy.SQL)
This would work as follows:
- Create user REVIEW
- Register user REVIEW to repos QA
- For a module you want review for, set the status to QA
Now the REVIEW user logs in and he can look at QA but cannot touch.
Hope this helps,
Jean-Pierre
In your situation

OWB 10gR1 Repository and 10gR2 Database

Hi,
we have a problem in installing OWB Design Repository 10gR1 on 10gR2 Database. The Repository assistant hangs with message "INS0003 The User should have DBA privileges to complete the installation". I'm connected as SYS....
Regards,
Hakon.

Her is a workaround I get from Oracle, may it works. Till this time I can't test it, try it on your own risk.
Regards
Norbert
>>
Using the 050621 shiphome release of 10gR2 on Linux we have noticed the INTERACTIONEXECUTE stored procedure is defined with definer rights - it should be invoker rights.
Using the stored procedure to create an AW will create the AW in the SYS schema.
The only workaround is to redefine the stored procedure in the SYS schema with invoker rights.
CREATE OR REPLACE function interactionexecute(input CLOB) return varchar2 AUTHID CURRENT_USER

How to open the OWB Design Center in Linux

Hi All,
Currently, our OWB10.2. is installed in the Window2003 server, I could login the servers and go to Program -> OWB -> Design Center to open the Design center and create my own project or mapping.
We just install OWB 10.2.0.4 in a Linux Ret Hat server, I don't know how to open the Design Center from the Linux.
Should I open it from the Linux server(How), or I could remotely launch the Design Center from my PC (Window XP) to create my project (actually try to migrate project from the weindow2003 server to Red hat Linux server)?
Thanks
Kevin

Hi David,
I found the file and executed it, but got this list of errors, do you have any idea?
Thanks

How to deploy and run of a mapping created in owb in developer suite

Hello, could you please help me to check where is wrong?
I use WAREHOUSE BUILDER of ORACLE 9I DEVELOPER SUITE and I do it as below:
1, create a OWB REPOSITORY named "OWB" with WAREHOUSE REPOSITORY Assistant in the SUITE ;
2, create a OWB Runtime REPOSITORY named "OWB1" with WAREHOUSE Runtime Assistant in the SUITE;
(i wonder why not to ask me to create a connected user and target schema like in OWB product alone?)
3, open OWB CLIENT and create a new project named TESTPROJECT;
4, create a source module and a target module.
5, create a simple mapping, which is the field link between two tables which
have the same structure(i swear that any vertified error will not occur).
6, select this mapping and choose Generate in the menu of "module". Then select
"Generate Script" in the window of Generation mode, Then select Deploy in
the window of RESULT Generation Window after altering the tab of Mapping, and fill in the user information
which is the same as OWB Runtime Assistant. After select Creation button in the
window of data-base deploy, it shows the error that "table or view do not
exist".
I don't know where is wrong or this error means? And how to solve it?
Is there anybody help me?
and what the diffence on earth between the OWB in the DEVELOPER SUITE and the one as a single product?
Thanks a lot in advance!

could you please help me to check where is wrong?

How to organize work in OWB Design Centre to enable dimension sharing?

Hi all,
I'm looking for some guidance regarding the best way to go about organizing my work in OWB Design Centre to enable sharing of work already done and to avoid duplication.
Currently I have one area:
1 Project
4 Source modules
1 Target module with 3 dimensions
Now I want to start developing a new area (there will be about 10 areas in the end). This area must share 2 source modules and 2 dimensions from the target module. It should only use those dimensions, not be able to change it. Each area will be derived to a Business Area in Disco Admin.
How wil be the best way to do this:
- Should I create a new project or create another target module?
- Should I maybe have everything in one target module with 10 different cubes using selections of the dimensions?
- If I have different target modules, will I still be able to derive the Business Area to the same EUL?
Thanks!

Hi,
grouping cubes and their relating objects into a collection is a good help for oraganizing your objects for development.
For deployment, you have introduce some kind of (manual) release mangement.
We use the following process:
1. Add all objects belonging to a release to a collection "REL_V1" (you have to identify these objects manually)
2. Export this collection to a mdl file
3. Import the file into your target environment (e.g. integration, production).
4. Deploy the collection "REL_V1"
In december, I will give a talk about how to automatize this process using OMB*Plus on the german DOAG conference. The presentation and the code will be available for download on owb.metafinanz.de shortly after the conference.
Unfortunately, the presentation will be available only in german, but should give you the main ideas anyway.
Regards,
Carsten.

Find parent/child relationships At More Than 2 Levels

Hello,
Does anyone have a solution to find parent/child relationship for data more than 2 levels deep?
I have a solution when there's a simple parent-child relationship but not when there's a grandparent-parent-child relationship or deeper.
Ex. I have a table company_parent_child that stores the relationship betwen a company and it's direct parent.
create table TEMP_COMPANY_PARENT_CHILD
PARENT_ID NUMBER(10),
COMPANY_ID NUMBER(10)
insert into TEMP_COMPANY_PARENT_CHILD values (1, 10);
insert into TEMP_COMPANY_PARENT_CHILD values (1, 11);
insert into TEMP_COMPANY_PARENT_CHILD values (1, 12);
insert into TEMP_COMPANY_PARENT_CHILD values (2, 13);
insert into TEMP_COMPANY_PARENT_CHILD values (10, 100);
insert into TEMP_COMPANY_PARENT_CHILD values (10, 101);
insert into TEMP_COMPANY_PARENT_CHILD values (10, 102);
insert into TEMP_COMPANY_PARENT_CHILD values (11, 103);
1->
___10->
______100,101,102,
___11->103
Companies 100, 101 and 102 are under parent 10 and grandparent 1.
I need to create such a view or another temp table so that when I pass the parent ID, I will pull all the children on all levels. In addition, and this is the tricky part, when I join this new temp table or view to another data table without any parameters, the data should not be duplicate, ie. each company ID should appear only once.
create table TEMP_JOIN
company_id number(10),
order_id varchar2(10)
insert into TEMP_JOIN values (100, 'a');
insert into TEMP_JOIN values (101, 'b');
insert into TEMP_JOIN values (102, 'c');
insert into TEMP_JOIN values (103, 'd');
insert into TEMP_JOIN values (10, 'e');
insert into TEMP_JOIN values (11, 'f');
insert into TEMP_JOIN values (12, 'e');
insert into TEMP_JOIN values (13, 'f');
Thanks.

start by learning CONNECT BY/START WITH. once you've
written a query to read the grandparent-parent-child
relationship, then come back with more questionsYes. we did look heavily into connect by/start with, in fact along with "connect_by_iscycle","connect_by_isleaf","connect_by_root" as well.
Our dilemma is that when a joint is made between those two tables mentioned above TEMP_COMPANY_PARENT_CHILD and TEMP_JOIN, we are not able to create a view that would contain distinct company_ids, each mapped to a unique order id.
The problem is we cannot have this type of joint when there are "n" level relationship between companies (or company_id). Basically, I think we should have our unique order id mapped to a unique key. This unique key should be a specialized key that we can know at anytime the entire path of the ancestry which we can know by sys_connect_by_path(company_id,'/') path.
How do we know which path to take. The best bet is to "connect_by_isleaf" and just have the distinct "deep" path which form the specialized unique key. If you need help on this let me know. (A hint, sort by LEVEL and then do a rank after partitioning by company id and then filter the records by rank = 1, try this one!!!)
So, we will eventually have a joint (say Table X) like
PATH ORDER_ID
/1/10/100 a
/1/10/101 b
/1/10/102 c
/1/10 e
/1
/1/11/103 d
/1/11 f
I think this is the best view we can have to maintain a joint with no repetition along PATH as well as ORDER_ID. If you have any other thoughts, let me know.
Then you query by path using INSTR to pull records by company_id.
for example, if you want to get all the children for company_id "10" you would just say
select * from X where INSTR(PATH,10,1,1) <> 0
or if you want to get all the children for company_id "11" you would just say
select * from X where INSTR(PATH,11,1,1) <> 0
What do you think? Has anyone used the path information for traversing the tree? Or is there any article that tells us how to make effective use of sys_connect_by_path(company_id,'/') path.
Thank you. Hope it made sense!

Dropped Design Repository from OWB

I accidentally dropped the design repository from OWB. A backup copy has been restored to the DB, but still it's missing. Please help.

What OWB release you used and how did you create backup?
If OWB release is 9.2 and backup has been created with Oracle exp utility then you can try to use script Restore_repos.txt from OWB Sample code page (this is the sequence of actions for restoring design repository). Find this script at
http://www.oracle.com/technology/sample_code/products/warehouse/index.html
Maybe this document will work and for OWB10gR1 but I don't sure.

How to login to OWB Design Browser

Hi everyone,
when i try to open OWB Design Browser it is asking the following
details :
Oracle HTTP Server Host ______________________
(The Oracle HTTP server host you provide must contain the entire path including the domain name. )
Oracle HTTP Server Port _______________________
( The default Oracle HTTP server port is 7777. )
Oracle HTTP Server DAD ________________________
(The Oracle HTTP Server Database Access Descriptor (DAD) is the same as your Warehouse Builder design repository name or user name. )
where can i get these details ?
how can i log in to get into my local OWB design reports?
Please guide me,
Thanks,

Ashvin
These values come from the serever that is hosting your repository. The Design Browser is a web interface so you need to have an HTTP server running. In our case we are using the Apache software that loads with the database and we are runing it on a UNIX server.
The HTTP service must be started.
The port used is 7777 by default but you can change that in the Project->Preferences->Browser tab from within OWB. Set this port to whatever you have in that Browser tab.
The DAD, as the note says, defaults to the username of the Design Repository and is usually set up during the install. You can see the DAD's that are set up by using your browser and going to http://<servername>:<port>. There will be a link to the DAD set up screen.
Hope this helps a little. Good luck.
