SQL Developer Data Modeler -- JRE or JDK

Hi,
Primarily, can any of you confirm that I need JDK (or J2SE SDK as the error message states) - and not just JRE as it is stated on the download pages on OTN?
I have just downloaded "SQL Developer Data Modeler" w/o JRE. Primarily because I already have JRE 1.6.0_17 installed, so downloading it bundled should not be necessary -- and secondly I would not want to risk intefering with the automatic software updating of JRE done by my company's IT support staff.
I may well be a complete Java amateur, but shouldn't JRE be sufficient, if you only want to run java apps?
Cheers, K

Hi -K-,
Yes, I do get an error.
I get the prompt: "Enter the full pathname for java.exe:"
I enter: "C:\Program Files\Java\jre6\bin\java.exe"
Then I get the error message: "Cannot find a J2SE SDK installed at path: C:\Program Files\Java\jre6."
Which I interpret as JDK being a prerequisite for running the application -- though I do not understand why.
Looking back at the download I realize that I have version 2.0.0-570 and not the new 2.0.0-584. I will try that tomorrow.
Cheers, K

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
http://i30.tinypic.com/mt8ocn.jpg
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,

My installation experience of SQL Developer Data Modeler

Installed SDDM successfully at work (Windows 7 Enterprise 64-bit 4GB) and at home (Windows 7 Home Premium 64-bit 4GB) after many frustrating hours. Finally found the simple solution:
1. Download JDK 6u33 - Java SE Development Kit 6 Update 33 ( link below). Select download for Windows x64. I had issues using JRE 6u33 per installation instructions... possibly self-inflicted error.
http://www.oracle.com/technetwork/java/javase/downloads/jdk6-downloads-1637591.html
2. Download SQL Developer Data Modeler.
http://www.oracle.com/technetwork/developer-tools/datamodeler/downloads/index.html
3. Change "SetJavaHome ../../jdk" to "SetJavaHome C:\Program Files\Java\jdk1.6.0_33" in file:
...\datamodeler\datamodeler\bin\datamodeler64.conf
Be sure to change the 64 bit version of the config file.
To start SDDM:
1. Click datamodeler64.exe (in bin)
2. At prompt (first time only), enter: C:\Program Files\Java\jdk1.6.0_33
Hope this helps!

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

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)

Customising the Legend (Legend Box) - SQL DEVELOPER DATA MODELER

Hi,
Is there a way to customize the legend Box (obtained when you right click Show->Legend in the Relational or Logical model window) in the latest latest version of SQL Developer Data Modeler.
For example i would like to remove a particular attribute from the legend say Changed by or Author.
Thanks in advance.

Hi,
It is not possible.
There will be such option in the future.

SQL Developer Data Modeler scripting

Hi,
I'm looking for a new modeling software for my company. SQL Developer Data Modeler (SDDM) has many features that fit my requirements. But there are some things that I'm not sure can be done. I work mostly with Oracle databases but still need to support some legacy and non-sql databases. Please look at problems below and tell me if and how those things can be achieved. Any suggestions for alternative solutions are welcome too.
1) I need to be able process Database Model from command line without human intervention and starting any GUI applications, for example generate DDL script form the model. Does SDDM have any interface for that?
2) I want to be able to export Database Model into a file in a custom (legacy) format.
3) SDDM stores database description in xml files. Is xml format defined anywhere? Are xsd schema files availabe?
4) Is there a SDK available that would allow reading SDDM Database Model into a custom application for further processing?
5) Is there any Java library available that parses Oracle-11-compatible SQL and PL/SQL?
Thank you in advance
Tomasz Grygo

Hi Kevin,
thanks for sharing your thoughts. There will be much more advanced find/search facilities in next version of Data Modeler and scripts also will be covered.

SQL Developer Data Modeler - Relation to Foreign Key Generation

SQL Developer Data Modeler 2.0.0 Build 584.
I am having trouble with Relations to Foreign Keys when Forward Engineering a Relational Model from a Logical Model.
First of all, the Naming Standard is not applied to the Foreign Keys when I perform the Engineer to Relational Model.
So I right click on the Relational Model from the Browser and Apply Naming Standards to Keys and Constraints.
I uncheck everything but Foreign Keys.
Now, Foreign Keys are named according to my Naming Standards.
However, this process also performs renames on the Column Foreign Keys even though I specifically unchecked that option.
This appears to be a BUG in the software and I haven't found a way around it.
I tried using {column} instead of {ref column} in the Naming Standard Template for Column Foreign Key, but that simply resulted in renaming my columns to "{column}".
Please confirm and/or let me know of any work-around for this.
Thanks,
Dan

Hi Philip,
Thanks for the reply.
Is this recorded as a bug to be addressed in the future?
Should I submit this problem via Oracle Support?
The other work-around I came up with is to override every Relation name in the Logical Model with the name I want to use in the Relational Model.
When the Relational Model is Engineered, this becomes my Foreign Key name.
Of course, this is not how I want to do things, so I am hoping for a bug fix someday.
Regards,
Dan

SQL Developer Data Modeler: Logical model, unable to create arc

I have a logical model in SQL Developer Data Modeler. Entity A has two 'incoming' foreign key relations to entities B and C. Both releations have the same optionality and cardinality. I want to place both relations in an arc. I see the buttons in my toolbar menu, but they are not enabled. Even when I select both relations it is not.
Bringing the logical model to the relational model creates foreign keys. These foreign keys can be selected and when I do that the 'Create new arc' button in the relational model toolbar is enabled.
What am I missing in the logical model ...? The documentation doesn't give a clue.
Erik

Thanks Sue, that worked. It is different from the way the ERD in Designer worked. Is there any reasoning behind it. As far as I know you should only put into an arc two or more relationships pointing to the same entity with the same optionality and the same cardinality. Selecting the entity with the relationships can only help in identifying at which relationship end the arc should be created but that is obvious.
And asking the question is answering it: it will help in adding an arc to two or more entities originating and ending at the same entity (and same cardinality and optionality).
Is that the reasoning behind it?
Regards
Erik

How can I find out what is causing this error in SQL Developer Data Modeler

Friends,
I am trying to import entities into into SQL Developer Data Modeler from Oracle Designer 10.1.2.3.
In case of need I perform these steps to perform the import:
File --> Import --> Oracle Designer Model --> Select database connection --> Select work area --> select application system --> select one entity --> Click finish --> Import starts
During the import process I see an alert dialog box with the message:
There are errors in import - check Log file Clicking Ok dismisses the alert box and I see the following summary screen:

Thanks in advance for any help you may be able to provide.

No this helps a lot. It's not strange. Firstly, in a versioned repository you should see Private Workareas and Shared workareas, so your workarea may be in either of these. It won't be in the Global Shared Workarea, as this only for non-versioned repositories. (I like to open the RON by selecting the full Repository, that way I can see the private and shared worlareas and the configuration and containers all in the same tree.
Now your workarea is defined by a set of rules, so when you expand the workarea in the RON, and select the object, then that's the workarea and object you'll see in the import dialog in the Data Modeler. So if you check it out and check it back in, and can't see it in the RON, then the rule is not seeing this object. (Did you refresh the workarea in the RON?) If you can't see it in the RON, you can't see it in the Data Modeler. If you're working in a versioned repository, you need to work in the specific work area, i.e V27 and this is what you need to select in the Data Modeler.
It looks like you are selecting the wrong workarea in the Data Modeler.

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.

How to install SQL Developer Data Modeler 3.1.1 for Mac OS X?

How do I install SQL Developer Data Modeler 3.1.1 for Mac OS X? I downloaded the file "datamodeler-3.1.1-703-macosx.gz" from OTN, but there is only a single file inside this archive - "datamodeler-3.1.1-703-macosx". What am I missing here?
Thanks in advance...

Extract that file and then run it.
Once you installed the tool to your Applications folder (if you choose to move it to Applications), you'll need to install Java (maybe).
What version of OS X are you on?
In a command window/terminal, type 'java -version'
If you get something back like 'java version "1.6..." then you're all good.
If you're on Mountain Lion, then type 'java' instead. That should download java for you.
Once you've got java available, then launch SQL Developer Data Modeler.
The installation notes are here if you want the official list of instructions

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.
