• How to build the data model to the server of short?

  After the Quick Start Guide, I am still confused of short components. In the view of BI, it should be a short server integrated data model and a tool to develop and manage the data model. Which component is this role, CloverETL or something?

  We have created a series of screencast "Getting started with short Information" discovered who should provide that you answer these questions.

  You can find the full outline on our page OTN: http://www.oracle.com/technetwork/middleware/endeca/learnmore/index.html

• How to rename items in the data model?

  I'm new to BICS and tries to rename an existing view, fact or dimensions. I am able to rename the entire data model, but not the individual items. This feature is available?

  Don't think you can really... the only option I see is the following ("synchronization with the database"), but not sure it will work

  

• Join Materialzed views overlooking the Materialzed to build the data model

  Hello everyone, we are in a situation where we are looking in the process of creating views Materialzed and possibly to join these views to an another Materialzed.
  
  Basically, instead of build real tables, we seek in this approach to speed up development time.
  
  Pointers? All the possible questions you plan?
  
  Best regards

  Hi once again a friend,.

  If you need to build a model quickly and you are clear what you have to do with the materialized view you can start at this stage. But remember that it's better to have a 'real' model with "real tables" instead of materialized views. Once you have a model in the production environment with MV, you can define and develop a model of real data with enough time.

  Kind regards.

• How to define a data model

  How can we write the data model based on query. And write XML.

  that Yes, I know... but I'm neighter Oracle development and product management...
  But when you start with an existing data model and add your changes step by step it is still currently not so difficult to write a data model. OK, it is not comfortable... but it works.

• I can create forms in the designer, but when I use a data model, I can't interact with the form

  In LiveCycle Designer ES2 I can create a form and then preview and interact with the form.

  This guess I just build objects by dragging the pieces pre-made object on the form (for example, text field) - which I can name, wrap in subforms something - I can add actions and all is well.  When I preview the PDF, I can enter data in the fields, click on the radio buttons, making things appear that everything is great.

  But LC ES2 is based on the data driven development model by, so in my case I need a form guide as well as the form - so it's better to have a model of data created in the first place - and then create the form based on the data model - then build guide form based on the data model - it is also a good idea, and I'm cool with that.

  My problem is that when I'm building a data model (just for a quick and dirty development demo, not associated with services back-end or databases) and I create the form based on the data model - I can't interact with all objects in the preview pane form - further when I launch the workspace and call my process that contains the form - I even can't interact with the form.

  What I am doing wrong?

  Summons - I can create a form and interact with it - but If I start with a data model and generate the form based on that - I can't interact with the form (option buttons click-I can not enter data in form fields - etc) what causes this?  What should I do to use a data model and be able to create an interactive form? >

  Does anyone know what causes this problem?  It's driving me crazy.

  Thank you-

  Ben

  You do not hurt anuthing. It works as advertised. When you generate a Guide and work with a fml data model designer you will only create a static non-fillable PDF file. This is because when you import the model in the designer of the model must be turned in a schema. The schema may not represent constraints and validations can be encoded in the model. The only thing that can be maintained is the structure, so Designer forbids you to buidl an interactive form.

  If you know what you're doing, you could take the data it is generated from the Guide and merge on a XDP template file that you create (unless he models in a first time - you can use the sample XML data as a starting point) using LC forms. Edowmside, is that if there are constraints and rules you would have to code them in the model as well. That's the way it is now there, but it will improve over time, as more of the ability of the model is exposed to the XFA world.

  Hope that helps

• Create sequences of data Modeler?

  Hello
  
  I started using SQL Developer Data Modeler to model my first APEX application, but there is one thing I don't understand.
  
  The logic model, I can create the model of my application, but I cannot find anywhere that I can define thath my PK should be filled from a when.
  Apex is a step in the wizard, the sequencing and the trigger, but if I have the model of the Data Modeler, then I have "let go" this important feature in common for most all of my objects table.
  
  There is something that I am missing?
  
  Kind regards.

  Hello

  You must set your PK column as "auto-increment" in the relational model. Also you can adjust the settings for this column to the "Auto-increment" page of the dialog column. Additional settings in ' preferences > Data Modeler > model > physics > Oracle.

• How to get the logical tab in the main area of 4.1.2 Data Modeler?

  I just installed Oracle Developer Data Modeler: Version 4.1.2.895.

  I was following section 2.1 development of the logic model

  http://docs.Oracle.com/CD/E48219_01/doc.40/e48205/tut_data_modeling.htm#DMDUG36169

  I used the example of library. I added the areas.

  Then I tried to create the books.

  The document says:

  1. In the main area (right) of the Data Modeler window, click the logical tab.
  2. Click the icon of the new entity.
     
     

  But I don't see the logical TAB on the right side at all.

  I see the Start Page. On the far right is the browser window. Basically, I see Messages - Log.

  On the left side, I have the browser window.

  Can someone tell me please how to get the logical TAB in the main area?

  Thanks in advance.

  Hello!

  In the browser with the right button on the logic model and select view.

  I hope this helps!

• Oracle SQL Developer Data Modeler start error

  Hi all
  
  I just downloaded Oracle SQL Developer Data Modeling (2.0.0.57.0) [released July 1, 2009] by selecting the option ' Oracle SQL Developer Data Modeler for Windows (this zip file contains the JRE).
  
  After that I installed the same and tried to start clicking on datamodeler.exe, I get the following error message
  
  "Failed to create an instance of the JVM on the path:... \jdk\jre\bin\client\jvm.dll.
  
  On the same machine, I can successfully run the SQL Oracle program without error. My machine is having Windows XP Professional SP3.
  
  Any ideas? If there is a problem with Java, that of the Oracle SQL Developer should also not run. But as I said it runs with any error, but the Oracle SQL Developer Data Modeler gives the above error.
  
  Kind regards

  Hey Jawad,

  you wrote you have 960 MB of RAM - how did you do a test with 1.5 MB of RAM and 2 MB of RAM?
  No doubt this is a problem of memory - memory change in the datamodeler.conf file option:
  -There 'AddVMOption-Xmx768M"by default; to take
  -"AddVMOption-Xmx512M" or never, making it suitable for your configuration - you can check the available free memory first.

• How to start collecting data through digital triggering entry user GOLD

  Hello

  I have a vi with which I would like to collect data. It is configured to start to perceive when the start trigger is detected, which works perfectly, but I would also create a user can start the process of data collection by pressing a button instead of apply the trigger. I am at a loss on how to do it. I thought that the structure of the event would work well; However, the relaxation has no Boolean value I can associate it with. If that were the case, I could then perform a logical comparison between the trigger and the button to determine if the collection of data should begin.

  So, how can I represent a trigger activated as a Boolean value? Or is there a better way to reach my goal?

  I think I can make things clearer by expressing in linear programming that it is, I'm trying to achieve:

  If (trigger == true: button == true) {}

  begin to collect data

  }

  I have attached my vi where someone feels useful.

  Hello

  You're right, 6229 USB is certainly not compatible with NO-Sync. However, you should be able to do with the DAQmx driver functions.

  If I understand correctly, you want to generate a graph of your analog input and have this file based on a triggered event entry. A line using PFI will not work for this particular function, but you can create a task digital input instead and pass the thread to a D e/s instead of a PFI line line. You can then use for/no-write the analog input file using a case structure depending on the State of the digital line.

  I hope this helps! Let me know if you have any other questions.

• How to take account of changes to the data model view controller page.

  Hi all

  I use jdeveloper 12 c on windows.

  I create adf form view control data.

  now, I change the country_id column in the layer of data model in the corresponding view and assign the value list.

  but in the moment of the conception, the country_id filed shows normal text field.

  Instead, I want it to become a part of the select list.

  How to do this? How to keep account of changes we make in the layer of the layer of viewcontoller model?

  I mean, if I change something in the model, it should be automatically reflected on my page that is in sight controller.

  Kindly guide me.

  Thank you.

  Hi Maahjoor,

  All you have to do is just to refresh your data control, drag and drop the particular column. Now you can see the list of values. Unless he used.

  Thank you

• How can I Data Modeler does not generate constraints on NNC_ tables?

  Hi all

  Unfortunately I have not found the answer using Google ;-)

  When I generate my DDL scripts on my model on some tables Data Modeler (version 4.0.0) automatically generates constraints on the columns of the table "NNC_" for example:

  CREATE TABLE STG_DURCHGANGSKNOTEN

  (

  ID NUMBER CONSTRAINT NNC_STG_DURCHGANGSKNOTENv1_ID NOT NULL,

  Kilometrierung VARCHAR2 (20) CONSTRAINT NNC_STG_DURCHGANGSKNOTENv1_Kilometrierung NOT NULL,

  Letzte_Aenderung DATE CONSTRAINT NNC_STG_DURCHGANGSKNOTENv1_Letzte_Aenderung NOT NULL,

  Knotentyp VARCHAR2 (100) CONSTRAINT NNC_STG_DURCHGANGSKNOTENv1_Knotentyp NOT NULL,

  Name VARCHAR2 (100),

  BZ_Bezeichner VARCHAR2 (100),

  GUI_Bezeichner VARCHAR2 (100),

  Spurplanabschnitt_ID NUMBER NNC_STG_DURCHGANGSKNOTENv1_Spurplanabschnitt_ID CONSTRAINT NOT NULL,.

  XML_Document XMLTYPE

  );

  How can I avoid this? I like to just get something like this:

  CREATE TABLE STG_DURCHGANGSKNOTEN

  (

  IDENTIFICATION NUMBER NOT NULL,

  Kilometrierung VARCHAR2 (20) NOT NULL,

  Letzte_Aenderung DATE NOT NULL,

  Knotentyp VARCHAR2 (100) NOT NULL,

  Name VARCHAR2 (100),

  BZ_Bezeichner VARCHAR2 (100),

  GUI_Bezeichner VARCHAR2 (100),

  Spurplanabschnitt_ID NUMBER NOT NULL,

  XML_Document XMLTYPE

  );

  Thank you

  Matthias

  Hi Matthias,

  The NOT NULL Constraint clause appears likely because 'Not Null Constraint Name' property is set to the column.  (It is indicated on the Panel "forced by default and ' in the column properties dialog box.)

  To stop these products, you can go to the Data Modeler/DOF of the preferences page (on the Tools menu) and set the option 'generate short form of NO forced NULL.

  Note that there now is a forum specifically for the Data Modeler: SQL Developer Data Modeler

• How to consume the data model library adf for the project?

  Hello
  
  I use Jdev 11.1.1.6.
  
  I have a workspace Jdev containing the business component (entity objects, view and application module objects exposing the your). This workspace is deployed to a library of the ADF. This library is packed with DB connection details.
  
  I have a different workspace Jdev which needs to consume this library of ADF data model. This workspace is actually just the layer view (no business at all components).
  I added the data library ADF model to his draft opinion and it is showing application module and your sub of the data controls.
  
  My question is: how will this project view to connect to DB when running?
  It allows the connection of packaged data model ADF Libabry? If so, how?
  or should I create a business under this workspace view, just the purpose of connection project? If Yes, then what is the use of connections, including creating the library of the ADF?
  
  Thank you
  JAI

  Hello

  It uses the connection in the library of the ADF. However, I recommend that not save you the database connect information in the library of the ADF. Instead:

  -set the ADF BC model to use JDBC data sources
  -In the library of the ADF, configure it to contain only the name of data source
  -In the view project (the workspace) set up the database connection that is exposed by the library

  When the library is imported, verify the Application resources--> connections and right click on the name of the connection that is imported to configure
