Joins in the physical layer

Hi,
I have a small doubt:
Is it possible to to give the Outer joins in the physical layer+ of the RPD.i.e.,left outer join,right outer join and full outer join.
If yes can you pls provide me any links related to that.
Thanks,
Chinna

Hi,
No we cannot have outer joins in Physicla layer.
We can outer joins in BMM layer.
In BMM layer - complex join can be full inner join or full outer join or whatever your criteria was,but in physical layer - physical join is always an inner join.

Defining Keys/Joins in the physical layer

When the keys and the join conditions are defined manually using a table's Properties dialog box in the Physical layer, do these keys or joins also get defined in the database automatically? My understanding is that it does not get created in the database. So what I am trying to understand is - once the joins are defined in the RPD physical layer, do I have to then define the indexes/constraints in the database as well?
Thanks,

Not required. Indexes can be created in DB on joining col for performance purpose only.
Hope this helps

Combining multiple databases into one in the physical layer

I have several databases in the physical layer that I would like to combine into one database. How can I do this safely without interfering with the existing physical joins in the physical layer and the column mappings in the BMM layer ?
Can you recommend the best procedures to follow in order to get this accomplished?
Boniface Ntawutarama

hi Boniface,
I think so No,you cant combine all databases into single one.Actually why you want to do this?
According to the requirement you select a database and concerned tables to build the repository,same way with other databases also you build RPD and establish joins in physical layer
Lets wait for any more specific answers on this from experts.

Creating filtered view on the physical layer ussing session variable USER

Hi:
I´m creating a view on the physical layer, the view needs to be created dynamically. So depending on the user (using the session variable USER) the view is created with the data a particular user is able to see.
Fisrt I imported the table and changed it´s properties to be created through a "Select Statement" so i don´t needed to change the mapping on the bussiness model layer.
The consistency check was OK but i´m not able to see data in answers, even using the Administrator user. Have anyone tried to do this? Here is my query.
Thanks
A Garcia
Select * from D_ESTRUCTURA_RH2 where Region_ID
IN
select distinct a.REGION_ID from APP_INDPERSONAL_DM.D_ESTRUCTURA_RH2 a
inner join (
select distinct b.REGION_ID from APP_INDPERSONAL_DM.D_ESTRUCTURA_RH2 b
where exists (select 1 from APP_INDPERSONAL_DM.Autorizacion a, usuarios c
where a.app_id = 1
and a.usuario_id = c.Usuario_Id
and UPPER(c.Nombre_Usuario)=UPPER(':USER')
and a.miembro_id = 'REGION_ID'
and a.operador = '='
and (b.REGION_ID = (case when valor = 'Todo' then 0 else valor end) or valor='Todo'))
) seguridad
on
a. REGION_ID = seguridad.REGION_ID
)

whay not use the same filter in the content tab of the logical table source?
check the physical sql sent to databse using web-admin-manage sessions-view log and see if there is any unexpected behavior. also run the same query in db and see iff you get the results in databse itself.

Multiple joins Problem in Physical Layer.

I have two tables Departments and Employees in the physical layer of admin tool. When i am trying
to create foreign keys at physical diagram its giving error.
Scenario:
Departments
===========
Department_id (PK)
Manager_id (FK)
Employees
========
Employee_id (PK)
Department_id (FK)
Manager_id (FK)
1. Manager_id of Departments table references Employee_id of Employees table
2. Department_id of Employees table references Department_id of Departments table.
3. Manager_id of Employees table references Employee_id of Employees table.
I have done 1st one. After 2nd one i have tested for consistency check, the following error is coming:
[38015] Physical tables "Oracle DB Connection".."HR"."EMPLOYEES" and "Oracle DB Connection".."HR"."DEPARTMENTS" have multiple joins.
Delete new foreign key object if it is a duplicate of existing foreign key.
How to solve this?
How to do 3rd one also?
Please clarify.
regards
chandra kanth
Edited by: Chandra kanth on 08-Dec-2011 01:47

Hi,
I have created two alias tables (E1 Employees, D1 Departments) for Employees, Departments tables.
I have created foreign key joins as follows:
D1 Departments:
EMPLOYEES.EMPLOYEE_ID = "D1 DEPARTMENTS".MANAGER_ID
E1 Employees:
EMPLOYEES.EMPLOYEE_ID = "E1 EMPLOYEES".MANAGER_ID
and it is consistent also. Please let me know whether the above approach is right or not.

Why do we need to Join in the BMM Layer

Hi,
Somebody asked me the following questions
*"If the joins are already defined in the Physical Layer and ultimately the query will pass thru Physical Layer to the Database and will take the joins defined in the Physical Layer then why do the joins in the BMM layer". This can be a Complex join or a Foriegn Key Join*
Under what conditions do we use Foreign Key Joins in BMM layer ?
How do we use Stored Procedure in OBIEE?
Any answers.
Rgds,
Amit

This is most likely because the copy's licence has not been verified, and to verify it you need to log in so it can check that you account contains the license.

Duplicate table and Alias table in the physical layer

Hi,
I want a clear information regarding the duplicate tables in the physical layer of the rpd.
I mean what is the purpose of the duplicate tables in the physical layer.........
thanks,
chinna.

what do you mean by duplicate of physical table? is it Alias table?
if then,
-> aliases are created to break the circular joins (which are not supported by obiee)
-> and, as per apps standards no operation can be done on base tables which are imported directly to physical layer. Only aliases are joined and will be used in BMM layer
-> useful to re-use the table more than one time , best example: W_DAY_D in apps rpd

Logical joins differ from Physical layer joins

Can please answer to my Question?
1.How does Logical joins differ from Physical layer joins?
2.What is NQSConfig.INI file and what does it contain?
Thanks
Chi
[email protected]

2) The NQSConfig.INI file contains configuration and tuning parameters for the Oracle BI Server. There are parameters to configure disk space for temporary storage, set sort memory buffer sizes, set cache memory buffers, set virtual table page sizes, and a number of other configuration settings that allow you to take full advantage of your hardware's capabilities.
For more information about the NQSConfig.INI file parameters, refer to Oracle Business Intelligence Infrastructure Installation and Configuration Guide.
1) Logical joins are used in Business Model, Physical joins are used in physical layer. A key property of a logical join is cardinality. Cardinality expresses how rows in one table are related to rows in the table to which it is joined. Logical joins supports outer joins. so many else to mention... just go through RPD help file.

Additional join in rpd physical layer.

Hi,
I created a subject area joning all the tables in physical and BMM. Now I need to existing two tables with one more key. Can I just go the physical layer joins, double click on the join and add the new join there. Can we do like this or is there any process to follow. Please advice.

Issue while writing a query in table type select.in the physical layer

Hi gurus,
I am actually trying to create a table using select in the physical layer..... i acutally am not aware what it is called but its when i click a table in the physical layer i have an option table type and i chose select which allows me type my query..the query is
Select
coln name(which is a lengthly list of conversion) AS column_name
From Table name.
when i view the data rom the physical layer everthing seems to be fine. but when i try to view the data in the frnt end it gives me an error maximum length is too long than 128....
i am aware of this issue the sql server allows only column of length 128..but none of my column length is greater than 128..
Could you please help me in this
Many thanks in advance

hi veeravalli ,
Thanks for the reply....actually the corresponding reports for this have already been prepared...i created a view in the backend with the same select which i wrote before and and tried calling the view from her.. i have viewed the data and all is perfect...but when i try viewing it from the front end it error saying invaild object name select * from databasename.dbo.View_name...but i have checked the view exists in the backend...
Thanks in advance....

How to see the tables which are in the physical layer of SampleAppLite rpd

Hi Everyone,
I am new to OBIEE and I installed OBI Apps with Oracle 11g in my laptop. I tried to create reports using the OracleBIAnalyticsApps rpd. How can I know from which schema the tables are coming in the physical layer of the repository so that I can create a connection pool to the database. I got the default SampleAppLite rpd when I install the OBIEE but I am unable to see those tables in the database schema which are used in the SampleAppLite physical layer. Can anyone tell me how can I see the tables in the database which I see in the rpd. Actually my question may be wrong as I am new to this field, so please let me know if this is a wrong question. As I unable to express my question correctly. Thanks.

For the OracleBIAnalyticsApps rpd - the tables are under "Catalog" then "dbo" in database "Oracle Data Warehouse" in the physical layer. The RPD comes out of the box with the required connection pools - you dont need to create any. The connection pools "Oracle Data Warehouse Repository Initblocks Connection Pool" and "Oracle Data Warehouse Connection Pool" in "Oracle Data Warehouse" read the data from the business analytics warehouse that you created in a schema name of your choosing with the DAC. All you need to do is edit the user name and password and the data source name with a connect string - which is the local net service name to your database for default call interface OCI 10g/11g assuming you used an Oracle database for your warehouse. One way to test the connection pool is to right click any table/alias then "Update Row Count".
BTW Using the Admin Tool open the OracleBIAnalyticsApps rpd then do "Tools" then "Utilities" then "Repository Documentation" then "Execute". This will create a spreadsheet showing you all the mappings from the presentation to business to physical layers.

No row count in the Physical layer of the Administration Tool

Hi,
While creating physical layer, I imported tables and set connection pool.
After this, to verify connectivity, clicked Tools > Update All Row Counts.
Now according to Oracle online guide,
"when update all row counts completes, verify that the row counts are displayed in the Physical layer of the Administration Tool"
I do not see the row counts in the Physical layer of the Administration Tool. No error message gets displayed either.
Am I doing something wrong?
I am new to OBIEE.
Thanks in Advance & Regards,
Deeba

Hi Hammett81 ,
I think, I have given configured connection pool correct. (following Oracle guidelines: 'In the Connection Pool dialog box, on the General tab, verify that the call interface is set to Default (OCI 10g) and change the data source name to the appropriate tnsnames.ora entry ( ORCL in this example). Please note that this is the TNS service name, not the ODBC DSN. ' )
I tried to give ODBC DSN (SH) as call interface, which resulted in an Error dialogue, implying, previous configuration was correct.
So, I reverted back.

Deeba

Refreshing the Physical Layer ( New Columns)?

Hi,
I am new to OBIEE. (11.1.1.5)
I have a physical layer defined and now I have added some additional columns to these tables in the database.
Now, How to get these new columns reflected in the Physical layer.
I tried the Tools -> Utilities -> Update Physical Layer.
But it only checks for the data types of the existing columns already in the Physical layer.
Please help.
Edited by: 937825 on Jul 16, 2012 6:46 PM

Use File->Import Metadata option
The tables and column which are in RPD are grayed out and which are not available are in black.
Pls mark correct or helpful if helps
