Reverse Engg changes to Database

Hi All,
I am using Oracle SQL Developer Data modeler tool. Find it a very good tool for database designing. Here I can connect to Oracle database and get complete ER diagram, but I didn't see any place through through which I can Reverse Engineer changes made to ER Diagram back to Schema.
Do anybody have any idea about this.
Anybody?
Thanks,
Danish

Danish,
I'm not sure I understand exactly what you are after. So instead of explaining a lots of things, please take a look at the three new online demos on the [Data Modeler |http://www.oracle.com/technology/products/database/datamodeler/index.html] site on OTN. Once you've had a look at those, I think you can ask us again.
It sounds like you are looking for the update DDL scripts. These are created when you start to import the same schema into your updated model. On import you'll get a Merge dialog, which gives you the opportunity of Previewing the DDL. These will contain the update scripts. But before I go into more detail on that, there are some questions on that in the forum and I can write the steps, but first see if those demo are a help.

Table changes in database are not captured in ODI model level

Hi All,
Can any one help me how to fix the bug in ODI.
Table changes in database are not captured in ODI model level.
Thanks in advance

I created the interface which is running successfully.
Now i did some changes in target table(data base level).
I reversed the updated table in model section. Till here its ok
The table which is updated in the model section is not automatically updated in the interface.
I have to drop the existed datastore in the interface and and re do the entire process of bringing the updated datastore, mapping,etc..
Please tell the any alternate way.

How to change the database in a business area

Hello All,
I am trying to figure out a way to change the database that a business area connects to. When I created the business area I selected to look at tables from the default database. Now I need to change that setting to connect to a different database. The tables are exactly the same on both databases. I just need to change the database that the business area looks at.
Is there a simple way of accomplishing this? I want to avoid having to recreate the business area.
Thank you very much in advanced for your help with this matter.
Del Benavides.

Hi,
Select all your folders in Disco Administrator,ALT+ENTER to go to properties, then change the database from the default database to the remote database.
Hope that helps,

How to reflect db changes - Verify Database doesn't seem to work

I have changed a database (MS SQL Server) column from varchar 255 to varchar 1000, but the designer doesn't pick up the change.
I read that db changes can be picked up by using 'Verify Database' feature. It doesn't seem to work for us though. Is there any configuration to turn on for the feature to work properly or any work-around to refresh the database changes?
We are making the database connection using JDBC (JNDI) option since the report is being used in a Java web application.
Any comments or insights will be very much appreciated!

Hi Wallie,
Thank you very much for your reply! Here are the answers to your questions.
Are you able to create a new report off the modified database?
==> Yes.
Do new reports see the changes made to the database?
==> No.
Are the reports connecting directly to the database table, or is it a stored procedure, business view, universe being used?
==> Through a business view.
By the way, after trying so many things, I was able to figure out the reason. Since the report is using a view, not directly the table, the view itself had to be recompiled to reflect the table changes so that the view could pass the changes to the report. It was a very good thing to know. Your last question could have been a very helpful insight for this issue! Thank you so much again!

Facing problem while changing the database at runtime

hi everyone,
Before posting this thread, i have gone through the various posts addressing the problem....but still iam unable to get the solution for this problem.
The report has been generated in one system, so the database properties (connection string....) are hardcoded in the report file...
Now when iam trying to change the database, it is still connecting to the system where the report file was created.
I have tried the changeDatasource() method, but it didnot worked....
here is the code for changeDatasource() method
public static void changeDataSource(ReportClientDocument clientDoc,
 String reportName, String tableName,
 String username, String password, String connectionURL,
 String driverName,String jndiName) throws ReportSDKException {
 PropertyBag propertyBag = null;
 IConnectionInfo connectionInfo = null;
 ITable origTable = null;
 ITable newTable = null;
 // Declare variables to hold ConnectionInfo values.
 // Below is the list of values required to switch to use a JDBC/JNDI
 // connection
 String TRUSTED_CONNECTION = "false";
 String SERVER_TYPE = "JDBC (JNDI)";
 String USE_JDBC = "true";
 String DATABASE_DLL = "crdb_jdbc.dll";
 String JNDI_DATASOURCE_NAME = jndiName;
 String CONNECTION_URL = connectionURL;
 String DATABASE_CLASS_NAME = driverName;
 // The next few parameters are optional parameters which you may want to
 // uncomment
 // You may wish to adjust the arguments of the method to pass these
 // values in if necessary
 // String TABLE_NAME_QUALIFIER = "new_table_name";
 // String SERVER_NAME = "new_server_name";
 // String CONNECTION_STRING = "new_connection_string";
 // String DATABASE_NAME = "new_database_name";
 // String URI = "new_URI";
 // Declare variables to hold database User Name and Password values
 String DB_USER_NAME = username;
 String DB_PASSWORD = password;
 System.out.println("DB_USER_NAME......."+DB_USER_NAME);
 System.out.println("DB_PASSWORD......."+DB_USER_NAME);
 // Obtain collection of tables from this database controller
 if (reportName == null || reportName.equals("")) {
 Tables tables = clientDoc.getDatabaseController().getDatabase().getTables();
 System.out.println("Tables in reports........"+tables.size());
 for(int i = 0;i < tables.size();i++){
 origTable = tables.getTable(i);
 System.out.println("origTable........"+origTable.getQualifiedName());
 if (tableName == null || origTable.getName().equals(tableName)) {
 newTable = (ITable)origTable.clone(true);
 // We set the Fully qualified name to the Table Alias to keep the
 // method generic
 // This workflow may not work in all scenarios and should likely be
 // customized to work
 // in the developer's specific situation. The end result of this
 // statement will be to strip
 // the existing table of it's db specific identifiers. For example
 // Xtreme.dbo.Customer becomes just Customer
 newTable.setQualifiedName(origTable.getQualifiedName());
 System.out.println("newTable........"+newTable.getQualifiedName());
 // Change properties that are different from the original datasource
 // For example, if the table name has changed you will be required
 // to change it during this routine
 // table.setQualifiedName(TABLE_NAME_QUALIFIER);
 // Change connection information properties
 connectionInfo = newTable.getConnectionInfo();
 // Set new table connection property attributes
 propertyBag = new PropertyBag();
 // Overwrite any existing properties with updated values
 //propertyBag.put("Trusted_Connection", TRUSTED_CONNECTION);
 //propertyBag.put("Server Type", SERVER_TYPE);
 propertyBag.put("Use JDBC", USE_JDBC);
 propertyBag.put("Database DLL",DATABASE_DLL );
 propertyBag.put("JNDI Datasource Name",JNDI_DATASOURCE_NAME );
 propertyBag.put("Connection URL", CONNECTION_URL);
 propertyBag.put("Database Class Name", DATABASE_CLASS_NAME);
 //propertyBag.put("Server Name", SERVER_NAME); //Optional property
 // propertyBag.put("Connection String", CONNECTION_STRING); //Optional property
 // propertyBag.put("URI", URI); //Optional property
 connectionInfo.setAttributes(propertyBag);
 // Set database username and password
 // NOTE: Even if the username and password properties do not change
 // when switching databases, the
 // database password is *not* saved in the report and must be set at
 // runtime if the database is secured.
 connectionInfo.setKind(ConnectionInfoKind.SQL);
 connectionInfo.setUserName(DB_USER_NAME);
 connectionInfo.setPassword(DB_PASSWORD);
 // Update the table information
 clientDoc.getDatabaseController().setTableLocation(origTable,newTable);
Also i tried with replaceConnection() method...........it displayed the report, but with not column names and data
need help regarding.......
Edited by: abhishek.c1984 on Jun 25, 2009 10:02 AM

In the report i have two tables.............so before changing the database properties for each table iam printing their names.
The names are dispalyed correctly.......but once i set the table location...i.e through the following method..
clientDoc.getDatabaseController().setTableLocation(tables.getTable(i),newTable);
every time i can see only one table i.e. properties are set for the first table ........and each time the properties are being set for the first table only.....i dont no what is happening to the rest of the tables..
I have posted the method in the above post.....can any one please trace out the problem
Note: when i comment the following code, i can see all the tables
clientDoc.getDatabaseController().setTableLocation(tables.getTable(i),newTable);
when i uncomment it, i can see only first table repeating every time...

Getting errors after changing the Database

Previously I was using a different database connection for my adf application.Now i have changed the database connection through project properties->business components. I also deleted the details of the previous connection from connection.xml file. But still i'm getting the error about the previous connection.
Please share your opinion to get rid of this problem.

Try this.
1. Menu->View->Database->Database Navigator
2. Find your application specific connection.
3. Check properties of the connection, update/recreate, test the connection using Test button.
4. Menu->Build->Clean All

Changing the Database driver causing performance issue

Hello Experts
I am finding a strange issue where if I change the database to Oracle 11g ( you will find it if you click the database which you have created in physical layer) under Data Source definition the report takes a longer time to complete.
Actually I have upgraded the 10g rpd and catlog to 11g but database under data source definition was still using - oracle 10gR1 ( i donno whether this is a driver or not) . Everthing was running perfectly fine until I change the database under data source definition to Oracle 11g , the report takes a longer time . Also I found that the query is changed when I changed the database under data source definition to 11g.
Also to inform you that datawarehouse is Database 11g where the data lies.
what is the significance of Data source definition as changing it is changing the whole query.
Pls. help.

Hello,
Do you have the Full Oracle 11g DB Client installed on the same box where you are running your BI Server .? Also can you make sure you have copy of tnsnames.ora in following directories.
1. C:\Middleware\Oracle_BI1 \network\admin directory
2. C:\Middleware\oracle_common\network\admin
Check if the SQL Features that the datasource has , sometimes when you disable SQL features the server could issue a less effcient query to the database.
Thanks,

Reverse engineering for existing database

Hi,
I have two different databases, one with my application (i.e. DB1), and the other with the designer installation (i.e.DB2).
I want to get the Reverse Engineering of my app in DB1, and I know these steps:
- Design Editor> DB Admin tab> Generate> Capture design of > Server Model.
OK, but I get the "Create Database user" form, and the database and user name as "DEFAULT".
What do I have to do?
I just want designer to reverse engineer my DB1, and I think that it will store that meta info in the DB2. Am I correct?
I have created a new workarea and container for that purpose, but should I create a "Oracle database" before capturing the server model? and that database, should be the DB1 or the DB2? both are already created, so I think that I need just the connection.
thanks.

You've basically got this right - DB1 is the database you are capturing from and DB2 contains the Designer repository into which the metadata is being captured.
Designer wants to have a database definition and a schema definition in the repository to which it can attach your table definitions. In the Design Editor use the DB Admin tab to get to a place where you can create a database definition. Create an Oracle data definition for your application database (DB1) and create a schema definition (aka User) in that database to own your tables. Then those will appear as options in the Capture design of Server Model wizard.
Yes, I know - a lot of steps for what seems to be a simple task - reverse engineer an existing database. That's Designer for you. This is one of the reasons that I say that if ALL you want is to see your database in a server model diagram, Designer is overkill. But Designer can do SO MUCH more than that - if you want to fully use it, the annoyances are worth it.

Can I change the database Listener name in 11.5.10.2

Hi Hussen
Is it possible to change the Listener name and port on database node. My Application is of 4 node env. 2 rac database nodes 2 shared application tier nodes.
My requirement is to change the Database node listener name and port.
Thanks
reddy

Reddy,
It is possible -- Please see (How to change the hostname and/or port of the Database Tier using AutoConfig [ID 338003.1]) for details.
However, it is always recommended you have the ports on the application/database tier nodes within the same port pool -- See (How To change the Port Pool in the E-Business Suite 11i [ID 414439.1]).
Thanks,
Hussein

Change the database log on parameters in the run time with CR10 Delphi2007?

Hi,
I'm using crystal report 10 and Crystal VCL for Delphi. How can I change the database log on parameters in the run time?

You have to use the ConnectBuffer. See [this|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_erq/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes.do] note for details.
Also, consider searching the notes database:
https://www.sdn.sap.com/irj/scn/advancedsearch?cat=sdn_ossnotes&query=&adv=true
The search; VCL database crystal, returns a number of notes that may be of use.

Is it possible to change the Database default date format 'dd/mm/yy'

I'm inserting a date with the format 'dd-mon-yy' in a column, it gives the error:- " a non-numeric character was found where a numeric was expected ". I also tried the TO_DATE function but not successful.
I want to change the Database default Date format 'dd/mm/yy' to 'dd-mon-yy'. Is it possible?
version is (Oracle Server 7.3.2.0). I checked it on version ( Oracle Server 7.3.4.0) with format of 'dd-mon-yy'.
May I keep the both formats at a time?
Thanks for solution(s),
Tariq.

you can try with:
ALTER SESSION
SET NLS_DATE_FORMAT = 'dd-mon-yy';

How to co-ordinate changes in database and fmx if signature of package is changed?

There is a database parameter that define the dependency model of changes in stored procedures. I don't remember its name though.
One of its setting will let you run your form without the need to recompile if the stored procedure changed.
