SQL Data Modeler - Problem Opening Saved Logical Model

I created a logical model in the Data Modeler tool and saved it as a .dmd file.
When I try to open the .dmd file nothing pulls up. I get the following logs:
2012-11-08 11:09:45 - Building Diagrams
2012-11-08 11:11:25 - Open Design: 'CTS'
2012-11-08 11:11:25 - Open Design: 'OK'
I created a test model and saved it as a .dmdz file and I get can it to open. I tried to revise the file type of my original model to .dmdz and when I try to open, I get the following error message and nothing shows up.
"Some objects are not loaded correctly. See the log file for details." There is nothing in the log file.
Any ideas about how to get my .dmd file to open correctly?

What worked for me was going to Tools .. Preferences .. Data Modeler, and then making sure that each of the "Default <x> Directory" specifications pointed to a part of the hard drive that my operating system login user had permission to reach. (I suggest a sub-directory under your login user's "My Documents" or "Documents" folder, or whatever your operating system calls it.) Allowing the initially blank defaults produced weird behavior on my machine. YMMV.

  • PreparedStatement.setDate(1,java.sql.Date x) problem

    I am using Sun JDBC-ODBC bridge to access MS SQL Server 2000. I have following statement:
    java.util.Date date = new java.util.Date();
    java.sql.Date expire_date = new java.sql.Date(date.getTime());
    PreparedStatement pstat = con.prepareStatement("update account set expire_date=? where userid=?");
    pstat.setDate(1,expire_date);
    pstat.setString(2,userid);
    When I ran the program, I got a SQLException error as
    java.sql.SQLException: [Microsoft][ODBC SQL Server Driver]Optional features not implemented.
    I have traced the problem happened in the statement pstat.setDate(1,expire_date). I use jdbc-odbc bridge from j2se 1.3.1.
    I appreciate any help.
    Thanks, Brian

    May I refer to a recent topic where I explained a lot about date conversion between JDBC and SQLServer?

  • Problem opening saved emails

    I have saved my important emails to my flash drive and have always been able to open them.  For some reason, now I cannot access any of them and keep getting the same message.  It is:
    "Adobe Reader could not open ".......eml" because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded)."
    Like I said, it is for all of my saved emails and all have the extension ".eml".  Please help!

    Thanks for your help, Pat.  This actually did not work, however, in another post from 6/7/10, someone had asked about Adobe Reader 9.3 not working with Windows 7.  I see that you had answered that post also, but the problem was solved by graffiti.  Graffiti said that if you have both Reader and Acrobat installed on the same machine, you should uninstall one and repair the other since both fight for resources leading to various issues.  Once I uninstalled Reader, the problem was solved.  Thanks so much for taking the time to try to help me.  You actually did, by leading me to the correct answer.  Have a nice day.

  • Problems opening saved pdf files on desktop

    I can open pdf files in Mavericks Safari 7.0, but if I save it to the desktop and try to re-open, I get error messages.  However, if a pdf arrives in an email, I can save to the desktop and it opens perfectly.  Any ideas, please?

    Back up all data.
    If Adobe Reader or Acrobat is installed, there should be a setting in its preferences such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected. Otherwise do as follows.
    Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
    /Library/Internet Plug-ins
    In the Finder, select
    Go ▹ Go to Folder
    from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
    From the folder that opens, remove any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
    The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present. The same goes for a plugin called "iGetter," and perhaps others.
    If you still have the issue, repeat with this line:
    ~/Library/Internet Plug-ins
    If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.

  • SQL date query problem with century/ year

    We have an oracle database with about 6 million records. There is a date field called Entered Date that ranges from 1985 to the present.
    The majority of these records were entered prior to Jan 1 2000.
    If I run a query like
    select count(*) from (tablename) where entered_date < '01-JAN-00' I get 0
    if I do
    select count(*) from (tablename) where entered_date < '31-DEC-99' I get 0
    BUT IF I DO
    select count(*) from (tablename) where entered_date < '01-JAN-00' I get 6 million records
    or
    select count(*) from TREASURY.ctrc where entrydate > '31-DEC-99' I get 6 million records
    I've tried the same queries using 4 digit years but get the same results; it thinks that 2000 is the less than 1999
    How do I get around this?
    thanks

    Hi,
    975204 wrote:
    there are 6 million records on the table
    about two thirds have a date prior to Jan 1 , 2000How do you know that? From knowledge of the application, you may know that two thirds of them are supposed to have dates prior to 2000, but if
    SELECT  COUNT (*)
    FROM      TABLE_NAME
    WHERE      ENTRYDATE < TO_DATE ( '01-JAN-2000'
                           , 'DD-MON-YYYY'
    ;returns 0, that's pretty strong proof that none of them actually do.
    When I look at the dates , they display as 31-DEC-86Another example of why using 2-digit years is such a bad idea.
    I cant actually provide dump of this clients confidential dataSeriously; you can't provide one DUMP output? You've already said that it displays as 31-DEC-86, so even if the fact that 1 entry in the 6-million row table was done on December 31, 1986 was such a big secret, it's already out, and you won't be causing any more harm by showing the DUMP results.
    I ran the query with the same format as the date ie
    SELECT COUNT(*) FROM TREASURY.CTRC WHERE ENTRYDATE < TO_DATE ( '31-DEC-99'
    , 'DD-MON-YY'
    but same results
    if the column is defined as a DATE type, does Oracle make a distinction based on how the data displays, meaning does it think that 31-DEC-86 is different than 31-DEC-1986?No, all DATE columns have the same format. A DATE may be displayed one way of the other, but it is stored as neither.
    Do I need to convert all the data to a 4 digit year? You should always display dates with a 4-digit year.
    Run an update query that says if year >= 80 and <= 99 add 19 in front of the year, else add 20 in front of the yearLet's find out exactly what the problem is, first.
    Did you see Ascheffer's message? ^1^ It was dated just a couple of minutes before your last message, so you might not have noticed it. Run it to see what the actual 4-digit years are.
    If it shows, for example, that there are a lot of entrydates in the years 2080 to 2099, and you decide that all of those really should be 100 years earlier, then use ADD_MONTHS to correct them:
    UPDATE     table_name
    SET     entrydate = ADD_MONTHS ( entrydate
                               , -100 * 12
    WHERE   entrydate >= TO_DATE ( '01-JAN-2080'
                             , 'DD-MON-YYYY'
    AND     entrydate <  TO_DATE ( '01-JAN-2100'
                             , 'DD-MON-YYYY'

  • Engineer to Logical Model in SQL Developer EA4 causes problems

    I'm working with SQL Developer 3.0 EA4 (Build MAIN-03.97)
    Unfortunately I fond out, that it would be impossible to use the function " Engineer to Logical Model" any more after I change the relational model. In datamodeler.log I got the error message line "[AWT-EventQueue-0] ERROR MDBAction - java.lang.NullPointerException" for each time I use the function "Engineer to Logical Model". I try it out with the sample model "sh_cre_all.sql" and with following steps:
    1) Import via DDL File – no problem
    2) Engineer to Logical Model – no problem
    3) Change some attributes in the relational model – no problem
    4) Again Engineer to Logical Model – no problem
    5) Save, Exit an Open the sample – no problem
    6) Again Step 3 and 4 – no problem
    7) Add a table via drag&drop from an oracle schema – no problem
    8) Save, Exit an Open the sample – no problem
    9) Engineer to Logical Model no longer possible!!!
    Bernd

    I have experienced similar problems with 'Engineer to Logical model'.
    The scenario was following:
    Creating Logical model using 'Engineer to Logical model' from existing Relational model.
    Modifying the Relational model and 'Engineer to Logical model' again. No exception occured but the Logical model wasn't updated accordingly.
    Removing all entities from the Logical model.
    Trying to 'Engineer to Logical model' again. No entities were created in the Logical model (even after few tries).
    So I got to situation where I was unable to generate a Logical model, which was quite frustrating.
    The workaround was to create new Data Modeller project and import to it from the original project - the 'Engineer to Logical model' worked again.

  • 4.0 EA1 - Data Modeler does not open saved models

    Hi,
    When trying to open a Data Modeler design created by Data Modeler 3.3.1.748, the Logical Model is empty (has no objects) and the Relational Model is not opened.  Right clicking on the Relational_1 node and attempting to open the Relational Model yields an empty Relational Model (again no objects).  Since the Relational Model is empty I can't even try to open the Physical Model.
    I am able to successfully import DDL and Data Dictionary objects into a new model, however, after saving the model, If I try opening it with SQL Dev 4.0 or SQL Dev 3.2.20 with the 3.3.1.748 version of Data Modeler, none of the models are properly opened as above.
    Finally when closing a Data Modeler Design, the entire Data Modeler Browser tree disapears (the browser pane remains but is empty).  The only apparent way to recover the browser tree is to restart SQL Developer.

    I've started from a fresh install of EA1 without importing settings from v3.2.  Changed my look and feel to match my OS (Windows) enabled logging and set the logging directory.
    Now when I start DataModeler I get the following:

    For some reason it's trying to read C:\Program Files\SQLDeveloper\SQLDev-4.0.0.12.27\sqldeveloper\extensions\oracle.datamodeler.4\types\types.xml, however prior to running SQL Dev the oracle.datamodeler.4 directory does not exist although an oracle.datamodeler directory (without the dot4) does exist with the types\types.xml file.
    If I rename the oracle.datamodeler directory to oracle.datamodeler.4 then the data model opens partially, though all my relationships are missing and probably other stuff as well.  Further I get the following in the log:

    If instead of renaming the oracle.datamodeler directory to oracle.datamodeler.4 I copy it, then everything loads correctly, though models created with SQL Dev 3.2 have errors when opening the Physical Model, but once saved with SQL Dev 4's DataModeler, those errors do not reoccur.
    Is the fact that it's trying to read files from a nonexistant oracle.datamodeler.4 directory a bug?
    If not what should be in the oracle.datamodeler.4 directory?  Obviously not everything in the oracle.datamodeler directory, but at least some of the files are needed.

  • Logical model fwd engineer to relational model.  Missing FK relationships

    We are experiencing missing relationships in the relational model when engineering from logical model to the relational model. The logical model objects have properly defined primary keys defined. We are using SQL Data Modeler v3.1.700. Any suggestions on how to engineering these relationships without deleting the objects from the relational model.
    Thanks,
    Ed

    Hi Ed,
    I presume you had some relationships in the Logical Model that you were expecting to be engineered to Foreign Key relationships in the Relational Model.
    Please can you provide more detail to help resolve your problem. For example:
    Was the problem on an initial engineer from the logical model? Or on a re-engineer?
    Are you using Entity subtyping in your Logical Model?
    Are there any relevant error messages in the log file? (This is normally file datamodeler.log in folder datamodeler\datamodeler\log.)

  • DataModeler: Cannot engineer from logical model to relational model

    Hello,
    I have been trying for a couple of (very frustrating) hours to engineer a very simple logical model to its relational model. The toolbar button (and also menu option) that should do this just does nothing. No errors, no feedback, absolutely nothing!!! However I could engineer a relational model back to its logical model.
    I am using SQL Modeler version 1.5.1 build 525 on Windows Vista. I have closed and restarted the program many times but to no avail. Are there other factors (e.g. anti-virus, JDK etc) that could be responsible? But then why are other parts of the software working but not this one?
    Please kindly send your advice asap so I can proceed. I really like the Modeler and will not want to discard it.
    Thanks,
    Chiedu

    Hi Folks,
    I was able to figure out the likely cause of the problem. The version of Modeler (datamodeling-1.5.1-525-no-jre.zip) I used was downloaded without JRE. The current version of JRE installed on my computer is Java 6 Update 12 (build 1.6.0_12-b04). I suppose the two don't quite work very well together.
    I have now downloaded and installed another version (datamodeling-1.5.1-525.zip) with its own JRE and the problem was resolved.
    My guess is that the problem was due to the incompatibilities that may exist between Data Modeler and the various versions of JRE.
    Thanks.

  • SQL data extraction?

    Hi,
    can nay one here tell me what is SQL data extraction?
    in one on my requirements it was written simply SQL data extraction as flat file
    then modelling the data flow for the falt file to the BW.
    is it something related to database?
    explain me
    Thanks,
    Ravi

    Hi,
    it means that your flat file will be generated out of an database by SQL means (SQL = Structured Query Language).
    For instance your flat file will have the data returned by a statement like:
    SELECT FIELD1, FIELD2, FIELD3 FROM TABLE.
    The above is SQL but it can definitively be more complex (several tables, filters, grouping/aggregation...)
    Your flat file will then be loaded in your BW.
    Hope this helps...

  • SQL Data Modeler - Startup Problem

    Hi
    I've created a Relational Model with Oracle SQL Developer Data Modeler, with a few tables, and everything was working ok.
    Yesterday I made some changes to the model, added columns and another table, saved the model and closed the Data Modeler.
    Today - when I tried to open the Model, I only get an error "Some objects are not loaded correctly. See the log file for details"
    The log at the bottom of the Data Modeler only shows: "Open Design: "nameof model"" and no details of what went wrong. No other details is provided, and as far as i can see - and now I can't view the model at all.
    Any ideas how to find the problem/ fix it in order to get the created Model back?
    Thanks
    Coenraad

    Hi Philip
    Thanks, I found the log file there. I have cleared the log file, and when I tried to open the model again, it created the below information, any ideas what could be wrong?

  • Open Toad Data Modeler diagram with SQL Data Modeler

    hi, I've made a diagram with TOAD Data Modeler in Windows. Now I'm working with Linux, so I need a portable application to work with. Oracle SQL Data Modeler seems to be the solution to my problems, but I can't open/import my TOAD's diagrams into SQL Data Modeler.
    Anyone knows how to do it?
    Thanks in advance,
    Neuquino

    Hi Neuquino,
    there is no import from TOAD Data Modeler. You can generate DDL script with TOAD DM and import that script.

  • 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.

    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

  • Export logical model open all relational and physical model? -- Problem

    Hello,
    If I export only logical model ( file --> export --> To design Data Modeler) . Oracle Data Modeler open all relational and physical model, if I have 100 relational model open all, and this is very resource.
    Can it be avoided?
    Thanks.
