Oracle Database vs. ofa data model

• Data Modeler - compare models and DDL file

  I was the generation of DDL files by importing data dictionary. In the window to compare the models, the orange triangles with exclamation points show tables that are somehow different in the database and my data model.
  
  It would be a very useful feature, if she did not notice the type of information that never goes to the database. For example I used the Notes field and the table Types, and comparison feature shows that this information is missing in the database. In other words, it shows the exclamation points in each table, even if I had changed one table in my model.
  
  Is there a reason to make it work like that? Or is it going to be fixed in the future?

  Therefore the Data Modeler has not noticed that the sequence had changed

  DDL for new sequences is generated only - no. ALTER statements. Yet changes in the database can be merged into a physical model.
  I logged a bug for this.

• Data Modeler does not connect to SQL Server database

  I click connect on New / select connection to the base and nothing happens.  No connection is added to the list of connection in the Import Wizard dialog box (file-> import-> Oracle Designer model) so I can't go forward with the wizard and I can't connect to my SQL Server DB.

  The connection works very well according to the test and to connect buttons on the New / select connection to the base dialogue.  Initially, there was errors, reported originally by Test and Connect, but those that have been resolved with minor changes to the URL JDBC and CLASSPATH for jtds.

  Is there a Data Modeler error log which could give an overview of what's going on?  Everyone knows this?

  SQL Server 2008

  JTDS 1.3.1 and 1.2.8

  Thank you.

  Hello

  No connection is added to the list of connection in the dialog box Import Wizard (file-> import-> Oracle Designer model)

  This path is for the import of the Oracle Designer repository that resides on the Oracle database as well as the Oracle connections are listed here.

  You must use "file > import > data dictionary.

• Data modeling for a small database tutorial - understand the part 'Creating relationships between entities'

  I'm trying to understand and make use of Tutorial: modeling of data for a small database

  In this tutorial, I'm supposed to make Entity Transactions containing two attributes that designates the bosses (patron_id) and Books (book_id) (2.1.4) entities

  Later, I add two one-to-many relationships that attributes mentioned twice in the entity of Transactions (patron_id1 and book_id1). (2.1.5)

  So here are my questions: what is the purpose of creating attributed to point 2.1.4 if they are then reproduced in paragraph 2.1.5?

  If she could be crucial, I use Oracle SQL Developer Data Modeler Version 4.0.0.825 Build 825 on jdk1.7.0_25.

  Bonus question: how to turn attributes types on the logical diagram? I can't find the option anywhere...

  I would be really grateful for each answer and all the stuff!

  Looking at the documentation for version 2.  I checked 3.3 and 4.0 EA3 and corrected tutorial you can download the latest version and use this documentation.

• Model reusable SQL Oracle to create a DDL/DML Scripts for Oracle database

  Hello
  
  
  I have an obligation to set up a model of Oracle SQL to create the Scripts DDL/DML reusable for Oracle databases.
  Only the Oracle DBA will run scripts permissions is not a problem.
  
  The workflow for any DOF is as follows:-
  
  (1) new table
  
  a. check whether the table exists in the views system/admin.
  b. If the table exists then give message "Table exists".
  c. If the table does not exist then run DDL code
  
  (2) add the column
  
  a. check if the column exists for a given table of the system/admin views
  b. If the column exists in the specified table.
  B1. backup table.
  B2. ALTER table alter column
  B3. check data or execute convert dml sauvegardΘ to the new change script.
  c. If the column does not exist
  C1. backup table
  C2. ALTER table add column
  C3. Run dml to populate the column with the default value.
  
  The DML scripts are to populate the base tables with the data required for business operations.
  
  (3) addition of new line
  
  a. check if the line exists by comparing the old values of each column with the new values to be added for the new record.
  b. If there is, to give message line is
  c. If not exists, add the new record.
  
  (4) update existing record (we createtime columns in these tables as well as changes can be tracked)
  
  a. check if the row exists using the primary key.
  b. If there is.
  B1. off the record by using the "active" column of the table
  B2. Add new record with the necessary changes.
  c. If does not exist, add the new record with the necessary changes.
  
  Could you please help with some ideas that can get this done with precision?
  I tried several ways, but I am not able to set up something that meets all the requirements.
  
  Thank you

  If it helps at all. Sometimes we have a requirement for a DDL statement to be rerunable and her only error if something completely unexpected happens.

  It's a little monstrous, but basically, we wrap all DDL in a dynamic statement and capture errors that would indicate that the DDL script has already been run:

  Here's a bit of a model:

  declare
     w_ddl varchar2(32767);
  begin
     begin
        --
        dbms_output.put_line('Creating table TABLE_NAME');
        --
        w_ddl := 'CREATE TABLE MY_SCHEMA.TABLE_NAME
                  ( COLUMN_1     DATE          NOT NULL
                   ,COLUMN_2  VARCHAR2(10)  NOT NULL
                   ,COLUMN_3  DATE
                  )';
         --
        execute immediate w_ddl;
        --
        dbms_output.put_line('Successfully created table TABLE_NAME');
        --
     exception
        when others then
           if sqlcode = -955 then
              dbms_output.put_line('Table Already exists.');
           else
              dbms_output.put_line('creation of table TABLE_NAME failed:');
              dbms_output.put_line(sqlerrm);
              raise;
           end if;
     end;
  
    begin
        --
        dbms_output.put_line('Creating unique primary key constraint for TABLE_NAME');
        --
        w_ddl := 'ALTER TABLE MY_SCHEMA.TABLE_NAME ADD (
                 CONSTRAINT TABLE_NAME
                 PRIMARY KEY
                 (TABLE_NAME_ID) USING INDEX)';
         --
        execute immediate w_ddl;
        --
        dbms_output.put_line('Successfully created primary key on TABLE_NAME_ID');
        --
     exception
        when others then
           if sqlcode = -02264 then
              dbms_output.put_line('constraint already exists.');
           else
              dbms_output.put_line('creation of primary key failed:');
              dbms_output.put_line(sqlerrm);
              raise;
           end if;
     END;   
  
  <>
  

  It works well with our scripts to autmoated and help us when we iterate through development and back in if needed test environments.

  In this way, we can add the DDL statements to the deployment script and run the script again without error to set the database to the State required without having to run the newly created statement only.

  Sometimes this approach translates into a creation followed a statement alter table statement to add a column, but the end result of the script is always the same, and the deployment script can be controlled at source between iterations of development that is without having to restore the ddl changes to test the modified DDL script.

  hope that gives you some ideas.

• Developer of sql Oracle Data Modeling-diagram er

  Hello
  I tried to Oracle sql developer Data Modeler to see the relational ER diagrams.
  Tables are entered data maker but indicated no relationship between tables.
  Like this
  How can show the relationships between the tables?
  http://I54.Tinypic.com/30wxq1e.jpg

  SDDM cannot create a diagram with only simple table definitions. It requires primary keys (PKs) and the foreign key (FK) to be defined first. My guess is that you've imported these drawings from an existing database table. If so, this database does not contain these constraints. (I found this to be a problem in many organizations over the past 20 years - including my current job). You will need to determine:

  1. the PKs for each table (whether via the data profiling or to talk to someone who 'knows' what they are supposed to be, or by reading the logic/code of the application used to manage tables).
  2. the FKs between tables. You may be able to guess some based on column names, otherwise you will have to understand (ditto)

  Then you can update the model in SDDM with PK definiions (manually). You must do this before you draw in the FKs between tables. Now if you want a real entity-relationship model, you must create a logic model of the relational model. SDDM utility to convert the tables to entities and the relationships FKs.

  I have the basic steps with screenshots described in a presentation I gave in Denver at the end 2009. It was an earlier version of SDDM but the basics are the same. You can find the presentation here: http://www.rmoug.org/QEW2009/SQL%20Developer%20Data%20Modeler%20 (2) .pdf. Starting on slide 12.

• Calculate the fastest path between 2 nodes with the data model for the Oracle network

  Hi all,
  
  I have Oracle 10 g 2.
  
  My problem is the following:
  
  I created a network named ITALIA_NET in the data model for the Oracle network.
  The table of links of this network is named: ITALIA_NET_LINK$.
  The table of the nodes of this network is named: ITALIA_NET_NODE$.
  
  The table ITALIA_NET_LINK$ contains a field named COST that contains links (in meters) lengths.
  
  I've already calculated the SHORTEST PATH between two nodes of the network, by using the method of shortestPath() (using the Java API) as shown on "Pro Oracle Spatial for Oracle Database 11 g" manual. Infact, this method makes reference to the COST field for $ ITALIA_NET_LINK to make this calculation.
  
  Now, I want to calculate the FASTER PATH between two nodes of the network. I have the links (in hours) travel time to make this calculation.
  
  My idea is to create a new field in ITALIA_NET_LINK$ named Cost2 containing the travel time from the links and then do the math by using the shorthestPath() method, referring to the Cost2 field to $ ITALIA_NET_LINK COST field instead.
  By default, I know that the shorthestPath() method returns the COST field for $ ITALIA_NET_LINK. Is possible to change this setting and do that this method refers to the Cost2 field?
  
  In the alternative, is another way for the calculation of the fastest way?
  I want to leave the creation of another network as last solution, because I will have other costs of field (Cost3, cos4t,...)
  
  Thank you much in advance.

  Your approach is good. You will have two networks and you can read them in memory and analyze of shortest path. The shortestPath method is static for the class of NetworkManager. You can use the same method for both networks, once they are read into memory.

  ...
  read the network with time as cost of link
  NetTime network = NetworkManager.readNetwork (dbConnection, 'ITALIA_NET_TIME');
  read the network length as cost of link
  Network netLength = NetworkManager.readNetwork (dbConnection, 'ITALIA_NET_LENGTH');

  calculate the quickest way
  PathTime path = NetworkManager.shortestPath (netTime, startNodeID, endNodeID);
  calculate the shortest path
  PathLength path = NetworkManager.shortestPath (netLength, startNodeID, endNodeID);
  ...

  In the future, if you upgrade to 11g, network data model provides a load on demand (LOD) API that loads only the scores of necessary network in memory during the analysis. This command removes the restriction of the memory of the 10g (in memory API you use) API. API of LOD can handle very large networks and offers more features analysis and modeling capabilities.

  The following link contains the tutorial of NDM LOD API ready for download. Just for your information.

• 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

  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.

• Where should you install Oracle database and grid Infrastructure in order to comply with OFA?

  I downloaded two files compressed to the Oracle database installation, and both zipped install files for the grid Infrastructure.  The book I'm following for installation is said to use a directory of the database and a directory for the grid Infrastructure, but it does not explain where they should be located in OFA.  Probably they should both close up somewhere in the same Base of Oracle (since all Oracle related on a single file system should go in the same basis, according to my understanding), but it is not clear where they need to be installed over the other.  For example, the grid Infrastructure is a separate product that gets its own Oracle Home?  Anyone can shed some light on this process?

  Also, does it matter where the zipped files are uncompressed?  For example, use one of these files after the installation process, or OFA only cares location after installation?

  Yes, they go in separate oracle_home.  This should be explained in the respective Setup Guide.  This will be a CAR or a standalone ASM?  I have

  It does not matter where you unzip the installation files.  They are only used for the installation.

• Oracle SQL Developer Data Modeler 4.1 problem

  Hello:

  I m trying to use the new version 4.1 (BETA) of Datamodeler, but I have a problem at the time wherever I run the program.

  When I work the datamodeler.exe the console show me:

  UIDefaults.getUI () failed: no class ComponentUI for: oracle.ide.controls.StatusBarControl$ JDevStatusBar [, 0,0, 0 x 0, invalid...]

  Can you help me?

  Thank you.

  Hello

  Data Modeler 4.1 requires Java 1.8 can run correctly.

  If you try to run Data Modeler 4.1 with Java 1.7 it gets stuck in "Save the Extensions", and this error in the console log.

  When you try to start with Java 1.7 it normally gives a "JDK Version not supported" warning, which identifies the file that needs to be updated to refer to a jdk Java 1.8.

  Under Windows, this will normally be C:\Users\\AppData\Roaming\datamodeler\4.1.0.866\product.conf,

  But if you start from the console using the datamodeler64.exe it will use the file

  C:\Users\\AppData\Roaming\datamodeler64\4.1.0.866\product.conf instead.

  You can change this file.  Alternatively, if you delete the file, it should display the dialog box asking for the location of the JDK next time.
