Tables in SQL DEVELOPER DATA MODELER seem to be read only and have a chain symbol in the upper left

I have a bunch of tables in my data model. I have three relational models defined in this file. In one of the models, all the tables seem to be read only. They all have a chain in the upper left hand corner of their box.
I am not using version control, so that are not checked in or anything like that.
How do I unlock these objects? Why to they appear to be locked?
Thanks

It looks like you've linked tables across multiple models or designs.
Does this look about right?

Journal tables in SQL Developer Data Modeler

In my database I use journal tables, which can be generated automatically by Oracle Designer.
Now that I'm trying to start using SQL Developer Data Modeler, I can't find how to make journal tables with it.
Does anyone know whether Data Modeler supports journal tables or not? And if it does, how can I generate one?

No automatic generation you have to create them manually - use copy/paste to speed up the process.

Sql Developer Data Modeler 3.0 EA1: Relationship source and target names

When opening my version 2 model in version 3.0 EA1 the source name and target name of all my 231 relationships are deleted.
Is there a solution for this? I don't want to reenter these 462 labels...
Sincerely,
Marc de Oliveira

Hi Peter,
When I examine an XML file for a relation converted from version 2.0, the XML elements "nameOnSource" and "nameOnTarget" are missing in the converted 3.0 EA1 versionthey are not loaded during "open" of older design. If you define them they will go into XML file.

SQL Developer Data Modeler Definitions

I am brand new to SQL Developer Data Modeler, but not new to modeling (I've used Rational Rose for 8 years). Can someone point me to a list of definitions of the terms SQL Developer Data Modeler uses throughout its interface? I have poured through all of the help documentation only to find no such documentation.
Thank you in advance!
Craig Benson

Looks like you've run in something similar
Re: Datatypes changing on their own
Is column data type changing to Audio just on click of the column in Table properties dialog or you are doing something prior (add column, press Shift ...) ? Are you using domains ? Do you save model after importing or you trying to modify it right after import ?

Oracle SQL Developer Data Modeler start up error

Hi All,
I just downloaded Oracle SQL Developer Data Modeler (2.0.0.57.0) [Released 1 July 2009] by selecting the option "Oracle SQL Developer Data Modeler for Windows (This zip file includes the JRE)"
After I installed the same and tried to run it by clicking datamodeler.exe, I get the following error message
"unable to create an instance of the Java virtual machine located at path:..\jdk\jre\bin\client\jvm.dll"
On the same machine I can successfuly run the Oracle SQL Develper with no errors. My machine is having Windows XP Professional SP3.
Any ideas? If there was a problem with Java, than the Oracle SQL Developer should also not run. But as stated it runs with out any error but the Oracle SQL Developer Data Modeler gives the above error.
Regards,
JAA149

1 - The above problem has nothing to do with the memmory. I tried on a 400 MB RAM, 900 MB RAM, 1.5 MB RAM & 2 MB RAM with the same arror.
"unable to create an instance of the Java virtual machine located at path:..\jdk\jre\bin\client\jvm.dll"
http://i30.tinypic.com/9vkwf6.jpg
2 - There are two "datamodeler.exe: files
One is at D:\datamodeler\datamodeler.exe
2nd is at D:\datamodeler\bin\datamodeler.exe
The same error occurs with both the files.
3 - The Oracle SQL Developer Data Modeler version is "Oracle SQL Developer Data Modeler (2.0.0.57.0) [Released 1 July 2009]" and the file I downloaded is "Oracle SQL Developer Data Modeler for Windows (This zip file includes the JRE) - (57M)"
If I look in "D:\datamodeler\jdk\jre\README.txt" I find
"Java(TM) Platform, Standard Edition Runtime Environment Version 6"
If I run "D:\datamodeler\jdk\jre\bin\javacpl.exe" I get

If I run "D:\datamodeler\jdk\jre\bin\jureg.exe" I get
http://i28.tinypic.com/30boiyo.jpg
If i check at the control panle add/remove program
http://i30.tinypic.com/1428tba.jpg
If I go to "http://www.java.com/en/download/manual.jsp" and download "jre-6u16-windows-i586-s.exe" and run it.
If I go to "C:\Program Files\Java\jre6" I find the same files as in "D:\datamodeler\jdk\jre"
I am able to run Oracle SQL Developer with out any kind of error let alone the above one. But with Oracle SQL Developer Data Modeler I get the above mentioned error no matter what I try.
As the error states "unable to create an instance of the Java virtual machine located at path:..\jdk\jre\bin\client\jvm.dll". The file "jvm.dll" is located at two places. One at "D:\datamodeler\jdk\jre\bin\client\jvm.dll" and the second at "D:\datamodeler\jdk\jre\bin\server\jvm.dll"
A similiar problem occurs with JDeveloper with the fllowing solution
http://forums.oracle.com/forums/thread.jspa?threadID=506339&start=0&tstart=0
Which states the following
"hello!
in the problem with JDeveloper i have a solution. The jdk have a file jvm.dll in the path: jdk/jre/bin/client/jvm.dll this is the problem ... now in the path:jdk/jre/bin/client/ojvm has a file with the same name if you copy and paste this file to the another path, now its works fine your Jdeveloper.
Jdeveloper use two files to jvm.dll to work one in the folder /client and other in /server copy the same file to the two locations for precaution
for me work fine thanks..."
I tried to do the same (Copy from client folder to server folder)
D:\datamodeler\jdk\jre\bin\client\jvm.dll
COPIED THIS FILE TO
D:\datamodeler\jdk\jre\bin\server\jvm.dll
Nada. So I reversed it (copied from server folder to client folder)
D:\datamodeler\jdk\jre\bin\server\jvm.dll
COPIED THIS FILE TO
D:\datamodeler\jdk\jre\bin\client\jvm.dll
Does not work. So I tried another solution stated at the same forum entry
"Well,
i solved the problem by this way :
<SQLDEVELOPER>/jdev/bin/ide.conf
In this file, change this line :
AddVMOption -Xmx512M
by
AddVMOption -Xmx256M
Now, the executable is lauching correctly. No more errors with Java Virtual Machine.
But is it a good thing to solve it like that ?"
But the ide.conf file is only at "D:\sqldeveloper\ide\bin\ide.conf" which is for the SQL Developer and not the SQl Developer Data Modeler
Correct me if I am wrong but
JRE = Java Run Time Envoirment
JDK = Java Development Kit
And Oracle SQL Developer Data Modeler needs JRE and not JDK. In any case I download JDK
jdk-6u14-javafx-1_2-windows-i586.exe (121,306 KB) and installed it but no succcess.
I tried every thing except completely re-install my whole PC.
Any help will be much appreciated.
Cordially,

SQL Developer Data Modeling pricing

I just downloaded the EA version of SQL Developer Data Modeling. I read in the release notes that the production release won't be free - any idea about the pricing ?
Matthias

Once the pricing for SQL Developer Data Modeling has been confirmed, we will release the full licensing detail. This will not affect the SQL Developer licensing that exists today. We plan to release SQL Developer Data Modeling as a stand alone product and then as an extension to SQL Developer, for those who want to work in an integrated environment. You can download the second early adopter release of SQL Developer Data Modeling and test and use the product. Once we have a production release, we will not answer queries on the early adopter releases and the feedback application we are currently offering for this will be shut down. As such you can continue to work with the early adopter release, but it is incomplete and would be unsupported.

SQL Developer Data Modeler - MAC Version 2.0.0 Build 570 - Issues

In no particular order
- The Help, About box displays a different version information set then the SQL Developer Data Modeler, About SQl Developer Data Modeler.
- Not able to move any portion of the connection between entities. Thus there is no current way to align the lines as wanted.
- There is no way to scroll all the way to the right side if you have more then approximately 5 entities horizontally.
- Open SQl Developer data Modeler, Click on File, Open, select an XML file and a dialog box is displayed.
- The checkbox needs to be moved to the right as it is partially cut off.
- the text next to the checkbox is cutoff and only displays "Don't show this dialog agai".
- Printing Diagrams does not print correctly unless you have the entities displayed such that you can "read" them. If you have diminished the display so that you are not able to see the table or
field names then the Print Diagrams does not display the entity or field names.
- File, Recent Designs, does not retain the last or any design having been opened and/or saved.
- VarChar2 is not a displayed data type for Oracle 10G.
- There does not appear to be a way to create a set of fields which you would like to have added quickly and easily to selected tables.
- DDL Editor displays the Macintosh HD. It should display my User Directory

MySQL functionality within Oracle SQL Developer Data Modeler

Hi all,
I've read a few forum posts here that lead me to believe that MySQL is not currently supported by the data modeler tool (Link #1 I got to by clicking on the Statement Of Direction link on the main page SQL Developer Data Modeler</title><meta name="Title" content="SQL Developer Data Modeler"&g… Link #2 I got to by doing a search on the word MySQL within the forum search):
Link 1:
SQL Developer Data Modeler Statement of Direction
Link 2:
Can datamodeler be used with MySQL?
SQL Developer (not the Data Modeler tool, but the database admin-type tool not for modeling) does support MySQL using the latest MySQL Connector J 5.1 driver but, strangely, it doesn't seem the Data Modeler supports it, though. Can anyone please confirm that MySQL is currently unsupported for the Data Modeler tool? Thanks in advance.

Hi,
it doesn't seem the Data Modeler supports it, though.
Data Modeler doesn't have specific support for MySQL - i.e you cannot generate DDL for MySQL. Though you can import form MySQL server using JDBC connection in standalone DM or using created MySQL connection if you are using DM inside SQL Developer.
You can import definitions for tables(columns, PK and UK constraints, indexes, foreign keys) and views.

Foreign key Mapping based on Data - in SQL Developer Data modeler

Team
Do SQL Developer Data modeler supports Foreign Key mapping based on the Data in the Schema rather defined at the DDL ? For e.g if we implement a Objects Relation ship mapping in Data base, we don't define Foreign keys at table creation.
Toad does this feature through "AUTOMATIC FOREIGN KEYS MAPPING IN TOAD DATA MODELER" more info at (http://toadworld.com/Blogs/tabid/67/EntryId/905/Automatic-Foreign-Keys-Mapping-in-Toad-Data-Modeler.aspx)
any one know how to implement through some scripts also helps me
Regards
Raj

If you have table PKs defined and the candidate columns match those PK columns, then you can use the Discover Foreign Keys utility. Right mouse over the relational model name (node) in the left browser. It is about half way down the menu. I did a blog post about it last week on kentgraziano.com.

Oracle SQL Developer Data Modeler 3.0 Bugs, Resolution and workarounds

The purpose of this thread is to list bugs discovered while using ORACLE SQL Developer Data Modeler 3.0
Mainly with SQL SERVER 2005 and ORACLE 10g models.

SQL Server Physical model doesn't save table identity column.
here are the steps to get this bug:
1. create a table in relational model with a column as an integer to be used as an identity.
2. create or open a physical model for SQL-SERVER 2005
3. open the table in the physical model
4. edit the integer column property dialog
5. tick the identity check box and close the property dialog
6. save the model and close it
7. open it again, you will find the identity check is removed! (probably not saved from the start)

Domains usage in SQL Developer data MODELER

Hi,
I'm trying to understand how to use Domains in Oracle SQL Developer Data Modeler. We use version 3.1.3 . before I used Toad Modeler where domains are just part of your main design.
Oracle data modeler has some different concept.
let's assume I'm working on 2 designs: DesignA and DesignB that include relational models.
DesignA and Design B should use domains but list of domains in design A is very different than in design B.
Default domain file is located on c: drive where SqlModeler is installed. It is obviously unacceptable , so I need to change Default System Type directory in preferences.
And of course I want to have different domain directories for DESIGN A and DESIGN B.
So when I open design A then I changed Default System Type directory let's say to x:\AAA. Then i close design A and open Design B and change Default System Type directory to x:\BBB
I checked folders AAA and BBB and they have necessary XML files there: defaultdomains.xml, defaultRFDBSSites and so on....
Now questions:
can I rename defaultdomains.xls to something else like AAAdomains.xls? Domain administration can edit any domain file with any name , but how can I associate certain domain file with my design? My wish , when I open my design , then corresponding domain file will be open automatically. Is it possible?
If I open 2 designs in Sql Modeler and switch between designs then corresponding domain files should be changed automatically as well. Currently I shouldn't forget to change default System Type directory every time when I switch models. Is it the only way to handle it?
Thanks
vitaliy

Hi Vitaliy,
We use version 3.1.3
I recommend always to use the latest version. If you don't want to use beta (DM 4.0 EA is out) you can use DM 3.3.
Otherwise Oracle SQL Developer Data Modeler supports two types of domains:
1) DM installation domains - those in file defaultdomains.xml
2) Design level domains - they are stored in design directories and are visible to particular design only. They can be created in following ways:
2.1 Manually - there is a property "Domains file" and you id it's not set "defaultdomains" domain will become design level domain and will be stored in file with provided name (without .xml extension)
You can change later the file for design level domains, however you cannot change file for domain already in defaultdomains.xml.
2.2 Using types to domains wizard you can generate design level domains
2.3 Design level domains are created during import of DDL files (controlled in preferences)
2.4 You can import domains from specific file with domains using "File>Import>Domains" - you need to rename the source file if it's named defaultdomains.xml otherwise you'll get domains as installation domains
If the list with domains is too long you can define a list with preferred domains (or/and logical types) in "Preferences>Data Modeler>Model" and you can use shorter list in Table/Entity dialog if check "Preferred" check box next to "Type:" combo box.
If I open 2 designs in Sql Modeler and switch between designs then corresponding domain files should be changed automatically as well
If you open 2 designs in one instance of DM they will use the same file with default domains i.e. you'll lose domains in one of design depending of setting for "system data type directory". You need to go with design level domains.

Import / Export MySQL database in SQL Developer Data Modeler

Hello,
I have version 3.1.2.704 of SQL Developer Data Modeler and version 3.2.09 of SQL Developer installed.
When I´m adding a new connection in SQL Developer, I can choose the MySQL tab an create a connection to a MySQL database.
The connection test was successful and I can see all tables.
I use the same JDBC driver for SQL Developer and SQL Developer Data Modeler (mysql-connector-java-5.0.4-bin.jar).
But there are two problems.
1. First there is an problem when I want to import from a MySQL database (SQL Developer -> File -> DataModeler -> Import -> DataDictionary).
After choosing the MySQL connection and pressing the next button an error occurs: CONNECTION_TYPE
What is the reason?
2. In SQL Developer Data Modeler I have not the CONNECTION_TYPE problem. But when I want to export DDL, there is no MySQL type selectable, although there is working connection to the MySQL Database. It´s the same in SQL Developer.
What is the reason?

Hi,
Data Modeler does not explicitly support import from MySQL databases, although you can use a JDBC connection to do this.
Philip described how to set this up in forum message How to connect mySQL for reverve engineering
There is no MySQL tab in Data Modeler - you should use "JDBC-ODBC Bridge" - "other third party Driver".
Set URL like : jdbc:mysql://localhost:3306/database_name
driver Class: com.mysql.jdbc.DriverAlso Data Modeler does not support generation of DDL for MySQL.

Oracle SQL Developer Data Modeler Versus SQL Developer

Friends,
I'm trying to understand the differences between Oracle SQL Developer Data Modeler and the ability to use the Data Modeler in SQL Developer.
I've looked at both products home pages 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 stand-a-lone chargeable product whereas the use of the Data Modeler functionality of SQL Developer is free
2) The Data Modeler functionality within SQL Developer is basically a "viewer" I can create ERD's of my existing tables by dragging them into the modeler from the object navigator but that's about it. I can't save the diagram for later use or use it to change the structure of the table(s)
3) If I need to have "Oracle Designer" like ERD capabilities then I need to use Oracle SQL Developer Data Modeler (after purchase!)
4) Are there any other differences I have missed?
Thanks in advance

You can open any diagram created in the stand-alone product in the SQL Developer Data Modeler Viewer and navigate through all property dialogs and the full navigator, just like you can in the stand-alone product, but with no update capabilities. This allows developers to fully review the model and all properties, without making changes.

Bug report SQL DEVELOPER DATA MODELER

Hello,
I think i found a bug using Sql developer data modeler 2.0.0 build 584.
When importing a DDL file to create a relational model, foreign key constraints might not be created if foreign key uses multiple-field and the fields are not referenced in the same order as the primary key was.
ex:
Table FOO ..... PRIMARY KEY (id_1, id_2)
FOREIGN KEY (id_2, id_1) REFERENCES FOO (id_2, id_1)
Benjamin
P.S: Bellow is a portion of SQL code demonstrating the problem:
-- "_decompte"
CREATE TABLE "_decompte"(
numero_rang VARCHAR2(2),
numero_contrat VARCHAR2(13),
id_decompte VARCHAR2(19)
ALTER TABLE "_decompte"
add CONSTRAINT pk_decompte PRIMARY KEY (numero_rang, numero_contrat, id_decompte);
-- "_decompte_detail"
CREATE TABLE "_decompte_detail"(
numero_rang VARCHAR2(2),
id_ligne NUMBER(4),
numero_contrat VARCHAR2(13),
id_decompte VARCHAR2(19)
-- "_decompte_detail"
-- NOT Recognized by SQL DEVELOPER DATA MODELER (fields are not in the same order as primary key definition)
ALTER TABLE "_decompte_detail"
add CONSTRAINT fk_decompte_detail_1 FOREIGN KEY (numero_contrat, numero_rang , id_decompte) REFERENCES "_decompte"(numero_contrat, numero_rang , id_decompte);
-- Recognized by SQL DEVELOPER DATA MODELER
ALTER TABLE "_decompte_detail"
add CONSTRAINT fk_decompte_detail_2 FOREIGN KEY (numero_rang, numero_contrat, id_decompte) REFERENCES "_decompte"(numero_rang, numero_contrat, id_decompte);

Hi,
Well, I was recently given some database scripts and asked to correct and improve them. These scripts were not generated but rather hand made. Having no access to a DBMS I was just curious about the result of this option in Data modeler and tried it for a better DB overview. I don't need it at all, but I was surprised to discover that the result was a failure. So I tried various scripts until I found the mistake.
regards.

Does SQL Developer Data Modeler fit-in??

Hi Everyone,
Wish you happy new year 2011.
Does SQL Developer Data Modeler support conceptual, logical and physical in our modeling or only logical and physical?
We all use Erwin for modeling. Erwin works without database repository storing models in desktop folders and provide additional reporting. I find some place SQL Developer Data Modeler talked about repository need.
Does SQL Developer Data Modeler store the models in local/network folders instead of Database server?
What are the functions need database based repository to work with SQL Developer Data Modeler?
We are thinking of using SQL Developer Data Modeler for our conceptual, Logical, and data dictionary need. Will it help in our need?
Do we need to face any surprises on using SQL Developer Data Modeler for our need?
Thanks in sharing your experience and helping me out.
RI

1) Do we need to have Oracle database at back end to work with SQL Developer Data Modeler?No, Data Modeler use Oracle database only if you create reporting repository.
Data Modeler is free, you need database license only if you want to log service request
2) Will SQL Developer Data Modeler create any tables (as backend repository ) in Oracle database to store Model details? no
3) Do we need to create reporting schema in backend oracle database to generate reports of SQL Developer Data Modeler's items such as Entity/attributes etc?no, reports can be created out of current loaded design. However having reporting repository will give you additional benefits - history (reports can be generated for every snapshot of your designs there) and multi-user usage, you can create your own reports
4) Do we to use SQL Developer Data Modeler reverse engineer from DB2, SqlServer, Terra data etc?Data Modeler has full support for Oracle, DB2/390, DB2/UDB(LUW) and MS SQL Server. Reverse engineering from other databases (including Terra Data) is at generic JDBC level - you'll get some and some will be missing (no check constraints for example).
