Why ALIAS all the tables in the physical layer?

I build a RPD and keep see message (s) where it is suggested to Alias all the tables in the physical layer.

No reason?

Y at - it a PDF file / site that lists best practices for the construction of an RPD?

Thank you

In general, you may need to use more than 1 copy of a particular physical table. This means that you must use names of borrowing, even as you would in SQL. The advantage of using the alias is that when the physical table alias exchange all alias tables are changed automatically to change things in one place as if you created "copies" of the same physical table, you need to modify them one by one. We also use a naming convention names for each alias where the Dimensions get named Dim_ *, Fact_ * facts and bridge Tables Bridge_ * there has well listed more logically (in the way that you would use in the MDB layer).

  • How to set the join in the physical layer between the cube and the relational table

    Hello
    I have a data aggregated in essbase cube. I would like to supplement the information contained in the cube with data from relational source.

    I read the article http://community.altiusconsulting.com/blogs/altiustechblog/archive/2008/10/24/are-essbase-and-oracle-bi-enterprise-edition-obiee-a-match-made-in-heaven.aspx that describes how do.

    In this article, I think I have to define a complex join between any cube of essbase to my relational table in the physical layer.
    But when I use the Manager to join I am only able to define jooin between the tables of the source of the relationship, but not with the cube imported.

    In my case, I'm trying to reach the risk dimension in the cube based on risk_type_code (Gen3 members), with risk_type_code in relationship table dt_risk_type.

    How can I create this join?

    Concerning

    RelationTable.dt_risk_type = cube. "" Gen3, risk. "

    That's all ;-)

  • Could not import a custom in the physical layer table

    Background
    **********
    We are implementing the OBI Applications
    The RPD is OBI (analytical) applications, a. We created custom tables and are now building the logic layer.

    Problem
    *******
    Created a new custom table in the physical OBAW using the username of the OBI (analytical objects owner)

    Connected to the BI-Admin offline using the user/pwd administrator name

    Utility of used import, the appropriate custom table table (you can see in the dialog box), taken from the warehouse. It brings up the dialog box, and it looks like it is to import the table (by displaying the file flying over).

    Updating of the RPD. Even tried to connect and again.

    When you check the physical layer you do not see the custom table. Y at - it a cache that needs to be eliminated?

    have you checked if it creates a new connection pool and the table under this new connection pool?

  • When I click on "Show data" in the physical layer, the system throws an error of that connection failed

    Hello experts.

    I've download a RPD on my local machine. I have already imported all of the tables used in this RPD on my local machine. I created the DSN (obiee_reports), and the test connection is successful.

    I created a pool of connections with the DSN (obiee_reports). However, when I try to "view data" in the physical layer, the system throws an error "connection failed". Also, I am unable to create any analysis.

    I m do not know what I missed. Please notify.

    Thank you and best regards,

    If you use Oracle db then go to OIC as calling interface.

  • limitation of complex enter the physical layer

    Hi all

    Is there a limit on the modeling of MDB when we use the complex join in the physical layer. I have 1 and 4 Dimension table with more physical table relation.


    F-> D1-> D2-D3-D4 > >

    F.Col1 = D1. Col1, D1. Col2 = D2. Col2, D2. COL3 = D3. COL3 and D3. COL4 = case when D4. Col5 is null then D4. Another Col6 D4. End Col5)

    I use a complex join D3 - D4. In the report, I get the error [nQSError: 12002] communication to the Socket call = recv error: (number = 10038) an operation was attempted on something that is not a socket

    If I create the new calculated column CalCCol in D4 table in sql, containing the same logic (case when D4.) Col5 is null then D4. Another Col6 D4. End Col5) and using this join column in physics D3-> D4 (D3. COL4 = D4. CalcCol) in the physical layer, the report works without error.

    Should we do differently modeling in MDB layer or just this is a limitation with complex join in the physical layer?

    I don't think that there are limits for complex joins in MDB and physical layer. Correct me if I'm wrong...
    NQSError reg. : error 12002--> may be reason for cache currupted can see when it changes the online mode...
    Remove the cache and re-start the services that can help you.

    Assuming that you have mapped D2, D3, D4 tables D1 by add, button seems good.

    Send me your RPD record if you have any questions...

  • The physical layer Naming Convention

    Hello

    I am trying to install my physical layer and see the reference to name them correctly. When I look at the examples of sales, I see they use A01, A02, etc..

    But I have others indicate that I should their name:
    fact_sales
    dim_customers

    Anyone has any good advice on how to put in place a naming convention that is appropriate to the physical layer.

    And that I should just using this naming convention in names for the alias tables?

    Thank you
    Kathy

    Use as
    SALES_F and CUSTOMERS_D

    _F made
    _D for Dimensions
    At the top of case

    For Alias, use DATE (W_DAY_D) closing

    VVr,
    Again, you go ahead with the method described above, but be sure that you will do something weird here. You may face erros while creating a simple report based on 3 tables independent Sun for which I am not sure abt the granularity. Always do a test and for simple indicates it shud work well as BI server will automatically choose this made a model for SUN - SUN.

    A small question, why are you so stressed out creation made in the physical layer?

  • How to apply join types in the physical layer

    Hi all

    In Oracle Bi Admin tool, I've imported the views in the physical layer, and tried to reach points of view, now can we change the type of join in the physical layer?
    sound off for me, how can I register the type of join as "left outer" or "right outer" participates in the physical layer.

    can you pls help me, awating for your answers

    Kind regards
    Mary

    Hi Mary,

    In fact, you do not specify such information until the layer of logic (MDB). Just pretend that your physical join is an inner join for the moment. Put the tables in the MDB layer. Then look at the MDB joins. You will see that they are created as complex joins in the MDB layer, it is a best practice in the MDB layer. You will also notice a drop down which allows you to change the join of inner left outside/right external/full outer.

    Hope that helps!

  • In the physical layer star schema

    Recently, I came across a question from a colleague. The discussion continues as follows:
    He asked me what is the star schema, and where you can set? Physical layer or layer MDB?
    I've explained on the star schema and responded to his rest of the doubt that we define it in the layer of MDB.
    His immediate question is why can not we define it in the physical layer? Since MDB layer allows to build three-dimensional models, therefore, we must build it into this layer itself is my answer. But later in the evening, when I started to reflect on my way to the House, I started to think about his doubts.
    Here is what am curious that we can unite our physical layer tables too, why we can't define star in the physical layer? and why only in MDB? and what are the differences in the joints that we made in the physical layer as the layer MDB?
    I got tired of getting answers to these documents and in a few other online resources, but am not to succeed. Then, approach this forum in anticipation. Can anyof you help us to better understand these concepts.

    Yes, you need to (or is at least strongly recommended) to use complex joins in the MDB layer. I know that you can also use physical layers in the layer MDB, but I don't really know what happens when you do that and what are the consequences. I think I read once your knuckles are 'fixed' and the BI server is not to choose between the joints.

    So the idea is: set the 'true' joined in the physical layer using physical joints and define complex joins in MDB layer and let the BI server decide what physical join, it should use.

  • Problem definition complex join in the physical layer

    I have a problem with the definition of a complex join in the physical layer.

    I have the following two tables:

    DIM_ORG
    Id_Org
    DT_Start
    DT_End
    Nom_org

    FACT_REV
    Id_org
    Recipes

    The tabel DIM_ORG is type 2 SCD. The current/active nom_org can be identified in the table because DT_End will be empty.

    Using the expression builder to configure the physical join I have entered the following expression:

    DIM_ORG. Id_Org = FACT_REV. Id_Org AND DIM_ORG. DT_End is null

    The expression builder accepts the syntax, but when I want to close the physical foreign key window I get the message:

    [nQSError: 30001] Only the columns, designated operators and predicates are allowed.

    Any suggestions how to solve this problem? Am just missing something? All I want to do is set up a join to pick up the active nom_org of my size.

    Thanks for your help!

    Make a foreign key in the physical layer:
    DIM_ORG. Id_Org = FACT_REV. Id_Org

    In the MDB, set the logical table org dim source/content in tab/where a part:
    DIM_ORG. DT_End is null

    It seems that the RPD is looking for local tns config... try to use as hostname: port / ServiceName

    It should work, just in case where does not! stop to do so since it is question.
