hi all
if i create a view in the physical layer will it causes to performance issue
can any one suggest me on it,bez i have to create 3 views
thanks

Hi,
Using Aliases is a better way to increase performace. You can refer the Vanilla RPD. Aliases are extensively used ther.

Sql not supported in view in physical layer

hi, I wanna create a view (in physical layer)
table type = Select (under General tab in Phyiscal Table property)
I have checked the checkbox "Use database specific SQL".
and chosen "Oracle 9i" in Database tree.
the data structure in the table is in this thread methodology to get the result
the sql is
SELECT user,
MAX(decode(type,'A',value)) A,
MAX(decode(type,'B',value)) B,
MAX(decode(type,'C',value)) C
FROM tab
GROUP BY user
BUT when I click "View data" on the menu bar (right click the object in the phyiscal layer)
I get the error message.
Is max or decode not supported ? thanks

Could you please provide the error message that you are getting?
Cheers,

Views in Physical Layer

When creating a view on the Physical Layer, we get some white space to write a select statement on the window, Do we have nay parameter to choose the length of the space assigned.
My query is a long one containing many unions and i am running out of the space there.
Any parameter or config file where i can control the length of the space available ?

Hi,
If you create an opaque view ..the BI will Physical layer will have to complete all the joins at the BI Server level and then send it to the db..
while otherwise BI Joins will complete all the joins with the view and send it to the data base which would then replace it with the actual view query ...
so you leave less strain on BI server to start with
Secondly as a practice since view is a db object why not let it be in the db for the dba to maintain that in the repository where BI Admin has to maintain wrt future enhancements etc..There are various reasons to have opaque view and a view not as a database object atleast with high security level database. I cannot give out the reasons here though. But I am not able to accept your explanation of Joins. The joins happen in the database only and not on the BI server.

Creating views in Physical Layer of OBIEE Administration Tool

Hello,
I am doing a proof of concept of creating an OBIEE repository using the Administration Tool to make a model for an in house sandbox OLTP system. Because this POC isn't using a warehouse that is built nicely with everything I need, I am having to import the OLTP tables into the Physical Layer and then create a few extra views (by creating a new physical table object and selecting "Table Type: Select") to add some new columns I will need.
My problem is that once I have created two views 'ViewA' and 'ViewB', I want to then create a third view 'ViewC' that is the union of 'ViewA' and 'ViewB'. But when I create ViewC from these two views and try to then update row count or view data in newly created ViewC, I get an error message of the effect:
Message 208: Invalid object name 'DBO.ViewA'
Message 208: Invalid object name 'DBO.ViewB'
When I try and create ViewC with DBO.OriginalTableA and DBO.OriginalTableB, however, it works just fine. And I am also able to successfully update row count and view data in ViewA and ViewB independently. So it seems to me like a view initialization problem when trying to have ViewC be created from A and B.
Am I trying to do something that is not allowed in the Physical Layer of the BI Admin Tool? I would think that I should be able to work with views just like actual physical tables from my OLTP. Maybe not.
Any help or insight would be greatly appreciated. Many thanks.

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.

Different rows of a view in Physical Layer and Presentation Services

Hi all
From Administration tool you I have the view <View_Name> which has 3165 rows after Update Rows command.
The same number of rows is even when i make a simple select in TOAD:
Select count(*) from <View_Name>
The simple report has only three fields on Presentation Layer:
Asset Id-----Asset Number----------------Asset Description
This report displays 3101 rows.
I have done Reload Server Metadata, but no changes. Please help me to solve this issue.
Regards

Hi Sutirtha Roy
The problem seems in OWB because from here i can no see the rows in Presentation Service.
Or am I wrong??

Physical Layer Joins

I am creating a data model from a database that is in 3rd Normal Form. My understanding in the physical layer I should make the joins based on the relation between tables. I have a CUSTOMER & ADDRESS table and I understand that my join will be 1:M here since 1 Customer can have many addresses. However I would like to get all my facts from the CUSTOMER table so since this is going to be the fact table should the Many end of the join be at the CUSTOMER table. I have been given much misinformation about this and have 2 scenarios but do not know which is correct.
Scenario #1: Model the joins in the physical layer as 1:M e.g 1 Customer has many Addresses and then reverse the joins in the BMM to make the CUSTOMER table a fact table.
Scenario #2: Model the joins in the physical layer making the M (Many) side of the join on the Customer table therefore choosing it as a fact table in the physical layer.
Thanks in advance for any answer.

So if I understand correctly then the join in the physical layer will look like this: CUSTOMER------------->ADDRESSES. Is this because the CUSTOMER table is going to be the fact table. I thought the relationship between Customer and Addresses is a 1:M i.e. 1 Customer has many addresses. Why do we not model this in the Physical Layer.

Physical layer design in obiee 11g

Hi,
I need a clarification regarding physical layer degin in obiee 11g,I imported Oracle Apps reports ,but could not find any keys there at table level.So should i create keys on the imported table level or at the alias level of the imported tables.
Thanks-Bhaskar

If you import a transaction table you may have keys imported in physical layer but when you going with warehouse table you may not have keys at database level, you define them using join in physical layer.
We have surrogate keys in dwh.
Hope this clear your doubt, if helps pls mark

Read data using 2 diff connection pool for same DB folder in physical layer

Hi All,
i am using two connection pool which have different dsn connection information (both are directed to different database name or database server)..
so if i view the data of any table, a prompt will come asking for the connection pool, so how do i automize it....?
how do i set the different connection pool for different tables?
please let me know if u need further informtaion to understand my problem..
thnx...

thnx Stijn..
yupe that i know...
actually i have total of around 300 tables in physical layer (in both the schemas..) , around 12 fact and 100 dimension tables in bmm and same in the presentation layer...
so i think u can guess how many joins and other stuff, i have made in my bmm layer..
if now i will start modifying all this it will take lot of time...
i am just wondering that there is no alternative for this...
as when i check my data from the physical layer then a prompt ask for the connection pool (i have already made two connection pool..) so there could be some alternative way to automize the default connection pool setting for the tables/schemas folders in case if more than one connection pool exits under the same database in the physical layer...
isn't it?
thnx again..

Pass the filter to my physical layer view..

Hi,
My requirement is i need to pass the filter to my view (Physical Layer view).
Suppose if have a report with 4 or 5 prompts and 1 prompt am taking from that view (Physical Layer view).after running the report the query will be :
select a,b from x,(view (Physical Layer view)) where join conditions and where
prompt1='some value',prompt2='some value',prompt3='some value',prompt4='some value',prompt5='some value' (my prompts) (my prompts)
But my requirement is
select a,b from x,(view (Physical Layer view where prompt 5='some value')) where join conditions and where
prompt1='some value',prompt2='some value',prompt3='some value',prompt4='some value' (my prompts)
Hope you understand this..

Hi,
You want to pass the value from your dashboard Prompt to the physical layer view.
This can be achieved by using Request variable that you have the option of creating at the prompt level.
And then create session variable with the same name in RPD and now use that variable in the view created in the RPD physical layer in the where condition by calling the session variable.
Let me know if you need more info or if it does not work out for you.
Thanks.

Unable to view data in Physical layer of RPD

I have OBIEE installed on my local machine using Oracle 10g as the database installed on a remote machine. I am able to create the DSN and test the connection pool on my local machine.
The Call interface is OCI 10g in the connection pool. I am able to import tables into the database in the Physical layer of the repository but when I try to VIEW Data in the physical layer, it throws me an error stating,
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor at OCI call OCILogon.
nQsError: 17014 Could not connect to Oracle Database.
I have oracle 10g client installed on my local machine. I am able to view the tables and the data from SQL PLus. In OBIEE i am able to import tables but cannot view data.
Any suggestions on what could be causing this?

Sounds like one of my common issues. After you do the import, go back and check the connection pool. What I typically run into is that it has switched to the OCI connection rather than the ODBC connection used for the import, but it is still using the name of the ODBC DSN that was used for the import. Change it to the TNS name or the host:port/service and try again.

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

) seguridad

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.

Admin Tool Error When Viewing Data in Physical Layer nQSError: 43093

I am trying to view the data in my Admin Tool in the Physical Layer, I am getting:
[NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred.
[nQSError: 43093] An error occurred while processing the EXECUTE PHYSICAL statement.
[nQSError: 17001] Oracle Error code: 904, message: ORA-00904: "STUDENT_NUMBER": invalid identifier at OCI call OCIStmtExecute.
[nQSError: 17010] SQL statement preparation failed.
I know why I am getting the ORA-00904 error (the data structure in the external database has changed the the column STUDENT_NUMBER does not exist). However, I am getting TNS Listener errors when trying to re-import the changed data structure (import -> through server). I have checked my ODBC connection and it seems that is not the issue. This functionality existed before (I did pull in the data structure, that is where my error is originating from). Is there something I am missing?
Any insight is appreciated.
Thank you,
Kyle

Hi,
After an upgrade, these kind of issues can happen for several reasons as below
1. Wrong OCI Call Interface. If ODBC 3.5 has been used an Interface in 10g, then the upgraded .rpd might still be using the same even when you have got a number of different options to choose from in 11g. To resolve issues of this type change the underlying database version in the physical layer of the .rpd. Once, you make this change you can see a variety of changes in the queries, performance etc for good.
2. After you did a 'View Data' on the table, go through the NQQuery.log to see the query it is firing (Yes, you need to have log level set for this user though) and analyze it from the DB end. See, if you run the query in the DB it is fast, but if it is the Admin tool that hangs up with this query. In this case check the network speed, database settings, system DSN driver etc.
Hope this helps.
Thank you,
Dhar

I also import the tables in Oracle BI administration tool with my schema username and password.
But my problem is i cannot view the data on the table in physical layer using my schema username and password.
Please help,
Thanks in advance

Hi,
I'm confused about the last bit, you did a database import to get the tables into the RPD, which worked, but now they are not showing in the phsyical layer of the rpd? They should be there under a database with the name of the ODBC/OCI that you used when you imported them.
If they are not there then this would make me think that the import of the tables has not worked, try importing just one and see what happens.

Importing materialized views from database into physical layer

Hi,
I have created materialized view in the database. When I try to import the materialized view into the physical layer in OBIEE 10G (using the import from database option), it is not showing in the list of available object. I have selected all the object types (tables,views etc.). Can you please let me know how to import the existing MVs in the database into the physical layer.
Regards
Vinodh.
