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.

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

Select
coln name(which is a lengthly list of conversion) AS column_name
From Table name.

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

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.

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

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

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.

Refreshing the panels when new content added?

Hey, guys. My first post here; hope I'm not too much of a JNewbie for you. :)
I'm getting my feet wet in Swing, working on an invoice program for work. I want it to look like a regular invoice, with fields for SKU, description, cost per unit, units, and total per line item. Right now, I have those five fields in a Jpanel that I add to the bottom of the layout.
The problem is that I need the ability to go to File => Add New Item... and have another JPanel with those five fields add to the bottom so a 2nd item can be added to the form below the first. I tried making a function that adds them to the panel, using the same type of syntax that the generated code (using a form builder in NetBeans) did. I don't see the lines get added.
My thought is that there is some function I need to call to redraw or refresh the panel so that the new components start drawing. However, my Great Javadoc Adventure has turned up no clues.
Can anyone please give me a hand with making this happen, or at the least coming up with an alternate solution that will achieve similar results?
Thanks much.

I tried revalidate() , but no change.
Here's the function I'm using to try to add the item...
private void NewLineItem()
javax.swing.JPanel jLine = new javax.swing.JPanel();
jLine.setLayout(new org.netbeans.lib.awtextra.AbsoluteLayout());
jItemCode.setHorizontalAlignment(javax.swing.JTextField.CENTER);
jLine.add(jItemCode, new org.netbeans.lib.awtextra.AbsoluteConstraints(0, 0, 110, -1));
jCourseDelivery.setHorizontalAlignment(javax.swing.JTextField.LEFT);
jLine.add(jCourseDelivery, new org.netbeans.lib.awtextra.AbsoluteConstraints(110, 0, 240, -1));
jItemQuantity.setHorizontalAlignment(javax.swing.JTextField.CENTER);
jLine.add(jItemQuantity, new org.netbeans.lib.awtextra.AbsoluteConstraints(350, 0, 110, -1));
jItemRate.setHorizontalAlignment(javax.swing.JTextField.CENTER);
jLine.add(jItemRate, new org.netbeans.lib.awtextra.AbsoluteConstraints(460, 0, 100, -1));
jItemAmount.setHorizontalAlignment(javax.swing.JTextField.CENTER);
jLine.add(jItemAmount, new org.netbeans.lib.awtextra.AbsoluteConstraints(560, 0, 100, -1));
jLineItemSection.add(jLine);
jLineItemSection.revalidate();
pack();
JLineItemSection is a JPanel inside my frame.
Any suggestions? I think the way I am using the AbsoluteContraints is screwed up, as I'm having a lot of trouble with the layouts in general. The form editor in NetBeans (at least, the version in 3.6) needs a LOT of work.

How to identify the SQLs which are using the tables and new columns

Hi
I m using oracle 10G Database in windows. Developers have added some columns in some of the database tables and were asking to check whether there is some impact on performance or not. I have not done this performance tuning before. Kindly help me how to proceed further.
How to obtain the sqls which are touching the tables and the new columns? It would be really great if you can help me with this.
Thanks

You can try to use DBA_DEPENDENCIES to get PL/SQL objects using tables: http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/statviews_1041.htm#i1576452.
However if SQL code is not stored in database in a trigger, a procedure, a function, a package or a view, it is impossible to retrieve all SQL code referencing some table from database dictionary: for this you would have to analyze application source code.

How to divide the totalorderprice in 1st query with totalorders in 2nd query and save the result in new column

SELECT o.OrderID,SUM((od.UnitPrice * od.Quantity) - (od.Discount/100))+ o.Freight AS TotalOrderPrice
FROM [Order Details] as od join Orders as o on o.OrderID=od.OrderID
GROUP BY o.OrderID, o.Freight
select distinct o.employeeid, count(o.OrderID)as totalorders from Orders o group by o.EmployeeID

As suggested above, you need a common key for JOINing the queries (CTE-s):
WITH CTE1 AS
(select distinct o.employeeid, count(o.OrderID)as totalorders from Orders o group by o.EmployeeID)
CTE2 AS (SELECT o.OrderID, SUM((od.UnitPrice * od.Quantity) - (od.Discount/100))+ o.Freight AS TotalOrderPrice
FROM [Order Details] as od join Orders as o on o.OrderID=od.OrderID
GROUP BY o.OrderID, o.Freight)
SELECT
FROM CTE1 INNER JOIN CTE2 .....
