• SQL Developer Data Modeler: logic model, impossible to create the arc

  I have a logic model in SQL Developer Data Modeler. Entity A has two 'incoming' relations of foreign entities B and C keys. The two releations have the same cardinality and optionality. I want to place the two relationships in an arc. I see the buttons in my menu to the toolbar, but they are not enabled. Even when I select the two relationships is not.
  
  What is the logic model for the relational model creates foreign keys. These foreign keys can be selected and when I do that the button "create a new arc" in the toolbar of the model relationship is enabled.
  
  What Miss me in the logic model...? The documentation does not give a clue.

  Erik,

  You must select the relationships and the entity, then the CRA buttons are enabled.

  Have removed and unzipped the installation once again without changing the error.

  After that, I started with another user on my computer, it the error does not occur.

  Is there a system folder to remove the configuration of my personal like jdeveloper and sql developer?

  I lose the most important features, for example. have no browser and cannot open a design.

  Hi Torsten,

  Thanks for reporting the problem. I logged a bug.

  You can view together as "list of system types" directory to "preference > Data Modeler"-probably no longer exists. I guess that the setting for this directory is empty when you start SQL Dev as a different user.

• How to create Spatial indexes in SQL Developer Data Modeler 4

  Hello

  What is the procedure to create a Spatial index in SDDM v4? I found myself at an impasse because of the following problems:

  (1) retro-engineering rate the spatial index, then I need to add them manually.

  (2) adding an index does not allow me to check the 'spatial', and does not allow me to add the sdo_geometry column in the index definition.

  (3) for the registration of the spatial properties for a table, I can not choose the name of the Spatial Index.

  I came across an old post (Data Modeler - cannot create a spatial index), but this post is no longer valid because SDDM V4 does not allow me to create an index without columns (definition of the incomplete index).

  Help is appreciated,

  Kind regards

  Richard.

  Hi Richard,

  Thanks for your update.  I'm scared, I was assuming you were using the stand alone rather than SQL Developer Data Modeler.

  I tried using SQL Developer 4.1.0.18.37 (ai2) using a thin connection and got the ClassCastException you have found.

  But when I used ai2 autonomous, maker of data using the same login details 'Advanced', it worked OK and imported from the spatial index.

  (I'm puzzled as to why these two seem to behave differently, as this is the version ai2 data integrated with SQL Developer ai2 maker).

  I then plugged and reverse engineering the same tables (yet) in a new model.

  Funny is that there is no error in the external journal this time, but the spatial properties are still not retroconcues correctly.

  Is it possible that you have not set the option to import the spatial properties?  I expect that the spatial properties would be imported or that the error should be registered.

  SQL Developer ai2 imported properly the spatial properties and the spatial index, when I used a basic connection and specified host, port, and SID or Service name.

  Another issue: SQL Developer relies on a certain JDK / JDBC library?

  Any Java JDK 1.8 should be good.

• Language SQL Developer Data Modeling

  When I installed SQL Developer Data Modeling 4.0, it came out a German version (maybe because I have German Windows).

  Now, the documentation is in English, it designates the menu names of dialog boxes with English names, I find not in the product.

  Thus, forum entries refer to the English properties.

  What should I do to install this product with the English language?

  Hello

  You should be able to find some datamodeler.conf and datamodeler64.conf in the datatamodeler/datatamodeler/bin subfolder of the folder that you installed (uncompressed) Data Modeler 4.0.0.833 in.

• Failed to connect to SQL Developer Data Modeling

  All,
  I use Oracle SQL Developer Data Modeler version 3.0.0.665 in an Oracle 10 g database environment. When I try to import CFDS, I get the following error message:
  

  NoSuchMethodError:
  oracle.i18.ntext.converter.CharacterConverterOGS.getInstance(I)Loracle/i18n/text/converter/CharacterConverter;

  I use the same connection to Oracle SQL Developer version 1.5.0.53 profile and my connection works fine here, but the same credentials in the Modeler SQL Developer data fails with the above error message. All thoughts, what causes this connection problem?
  
  Thank you

• Oracle SQL Developer with SQL Developer Data Modeler

  Friends,
  
  I'm trying to understand the differences between Oracle SQL Developer Data Modeler and the possibility to use the SQL Developer Data Modeler.
  
  I have looked at two home pages produced on OTN, http://www.oracle.com/technology/products/database/datamodeler/index.html & http://www.oracle.com/technology/products/database/sql_developer/index.html and would appreciate your comments on my findings so far
  
  (1) the Oracle SQL Developer Data Modeler is a paid product stand-a-lone while using the Data Modeler of SQL Developer feature is free
  
  (2) the Data Modeler in SQL Developer functionality is basically a "viewer" I create my existing table of DR. by dragging in the Modeler in the object browser, but that's all. I can't save the diagram for later use or use to change the structure of the or the tables
  
  (3) if I need to have 'Oracle Designer' as ERD capability so I need to use Oracle SQL Developer Data Modeler (after purchase!)
  
  (4) are there other differences that I missed?
  
  
  Thanks in advance

  Yes, you've nailed it!

  Have fun

• 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
  
  JAA149

  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.

• SQL DEVELOPER DATA MODELER tables seem to be read-only and make it a symbol of the string in the upper left corner

  I have a lot of tables in my data model.  I have three relational models defined in this file.  In one of the models, all tables seem to be read-only.  They all have a string in the upper left corner of the box.

  I use version control, so that are not archived or something like that.

  How to unlock these items?  Why they seem to be locked?

  Thank you

  Must not have been involuntary - you should have physically moved and dropped the tables/entities from one model to the other.

  If you want to copy them and be able to change in the future, use instead of copy / paste.

• SQL Developer, Data Modeler, cannot print

  I can't print any logic or relationship patterns of the Data Modeler.
  I'm currently running SQL Developer 3.0.04 on a Windows 7 PC and my printer works fine.
  When I run the print menu, it shows the number of pages that must be printed OK, I invoke the impression, but blank pages are printed.
  The sequence of menu that I used is:

  You can create from Modeler data using "file > export > schema considered" feature - repository will be created with the first exported design.
