Physical/Logical model that implement oracle database

Dear Forum's member,
I need documentation where I can see a grafical or a figure of the Physical/Logical relationship model that implement the Oracle object internally. It's not an specific example. It's about how oracle store the objects that it manage and are they related to the others.
Best regards,
José Guillén

I once used Erwin Design tool which can help in your task. I do not know if this is still around, since I used it in 2005.

Unable to Create Entity Model from existing oracle database

Hi,
I am using Visual Studio 2013, .net framework 4.5, entity framework 5.0 and oracle 11g database.
Issue Description: I need to develop WCF service to exposing the account information which needs to get the data from 20 oracle tables. Trying to create entity model from existing oracle database. first i tried creating just two tables it
was created but it took more than 30 minutes. then i selected remaining few tables it took more than a days but nothing created just showing spinning the wheel. then i tried with fresh project and selected all the tables but same issue nothing created and
also there is no error. during this process i checked database query monitoring there is a big sql statement collection tables metadata. i don't know what was wrong the query taking too much time to complete the process.
we tried multiple machine and different oracle database all are same issue.
Sql server database -looks good no issues.
Any help/tips/ideas welcome to overcome this issue.

Hi Sakthimp,
Welcome to MSDN forum.
Your issue is out of support range of VS General Question forum which mainly discusses the usage of Visual Studio IDE such as
WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help System
and Visual Studio Editor.
Because your issue only occurred with oracle database, moreover Oracle developed the Entity Framework for Oracle itself, I suggest that you can consult your issue on Oracle forum/community:
you will get better solution and support there.

Data Modeler goes to Oracle Database Repository ?

Hi Philip,
Thank you very much for your quick answer. Hope that this forum is the correct one right now.
To us it seems to be inpossible to use the data modeller v3.1 with SVN.
The recent designer-toolbox hasn't been updated by Oracle since 2007.
That's why we have created various interfaces and workarounds of our own:
A cg-refcode-interface with multilingualism, a table- and module-api, a hyperion application
to generate ddl-statements from case-repository (using user-extension for the new features of v10g).
These interfaces would not be possible with XML structure and would be discarded.
Central data modeling is a strategic approach for our company (financial) and has been
classified with risk class 1.
Because of this fact, I'd like to ask again:
Is there a timetable for converting Oracle's Data Modeler from XML structure to database?
By the way: This was promissed by Mrs Sue Harper in 2007.
Regards,
Reinhard

Hi Reinhard,
To us it seems to be inpossible to use the data modeller v3.1 with SVN. Why is that? Is it forbidden to use SVN in your company or you have other reasons.
Is there a timetable for converting Oracle's Data Modeler from XML structure to database? Not for functional repository. We have reporting repository and our target is all information to be there. You can have history of your designs (snapshot at specific time) in reporting repository and then you can run your tools against it.
That's for the moment. I'm not going to make other promises.

List of companies that use oracle database

Hello everyone,
I am studying Oracle DBA and I have to do a 6 month internship in the summer in order to finish my studies and get the degree. The question is: is there a way to find what companies/firms use oracle in the US?
Thanks in advance..

Dude company data is its real asset no body will allow you to make their valueable asset as testing Lab material. just get training from good professional take exam and do a lot of practices. This will make you a little champ in 2-3 years. Expert not before 7 years. So you should be consistent and patient in learning and earning.

ODSI service using function from oracle database

Hi ,
I need to create a ODSI service using function from oracle database.
I am not sure how to create a Physical Layer and Logical Layer using the function fron db.
Kindly provide a sample . I need It ASAP. Thanks in advance.
Regards,
Tara

Here's what you do.
Create New Physical Data Service -> Relational -> MyDataSource -> Table -> SomeTable ... finish the wizard.
So now you have a Physical Data Service that represents a database table.
Create New Physcial Data Service -> Relational -> MyDataSource (the same one as above) -> Database Function -> Enter UPPER for the Function name, enter MyUpper fro the XQuery Function. Finish the Wizard (use something like MyUpperDs for the ds name).
Open MyUpperDs. Right-click -> Edit Signature on MyUpper. Change the ReturnType to string, change the Occurrence to Zero or One.
Add a parameter, change the Type to string, change the Occurrence to Zero or One.
Save.
Now, open the first ds you made SomeTable.ds (whatever). Run it in the test view.
Go to the Overview tab. Create New Operation. Give it the name SOMETABLE_UPPER. Save it.
Go to the Query Map tab, open SOMETABLE_UPPER. Drag and drop SOMETABLE (the system-generated function into the mapper. It will show a dotted line from SOMETABLE to the Return. Now drag-and-drop the SOMETABLE to the top-level element of the return type, it will show solid lines from each element in SOMETABLE to each element in the return type.
Now, drag-and-drop MyUpperDs.MyUpper into the Query Mapper. Edit the source, find where it added the line "for $x in myd:MyUpper()" and delete that line.
Change a line that simply returns a value to use your function, for example, change
<FIRST_NAME>{fn:data($CUSTOMER/FIRST_NAME)}</FIRST_NAME>
to
<FIRST_NAME>{myd:MyUpper(fn:data($CUSTOMER/FIRST_NAME))}</FIRST_NAME>
Click on the Plan tab and Show Query Plan. You will see that in the query plan, it is using the database UPPER function where you specified MyUpper.
Go to the Test View and run it.

Oracle Database Authentication against Microsoft Active Directory

Hello
Does anyone know if it is possible or can point me in the right direction of some documentation that discuss Oracle database user authentication against and Enterprise Directory Service, in my cases MS AD?
My environment consists of Oracle RDBMS 10.2.0.3 on Linux Red Hat AS 4. Our users connect in from Window clients. I would like to know if there is a way to autheticate users from Windows to the database using LDAP based (AD) authentication. In oters words how do I configure authentication to be done for "identified globally accounts"? I know that the identified by globally accounts require the use of the CN which I have done, but it seems like there is some piece missing. Perhaps an Oracle schema or modification to Active Directory??
So my questions are
1. Is it possible to authenticate users against AD without the implementation of OID?
2. Is there documentation someone has or can point me to that outlines the required steps?
3. Anything I should know?
I appreciate any help. The documentation I have found so far doesn't seem to be what I need... So I am looking for some advice.
Thanks.

Sure, two methods to auth from Oracle DB to MSAD:
OID and OVD
I am working on our own proof of concept configuring EUS connect to OVD with an MSAD as auth at the moment. OVD basically is presenting the database with OracleSchema and OracleContext info. And when you connect via netca (ldap.ora), you assign it as OID directory authentication type.
Here's an OVD manual on Integrating with EUS (chapter 7 is for MSAD)http://www.oracle.com/technology/products/id_mgmt/ovds/pdf/e10286.pdf
And this would be what the EUS config should look like:
http://www.oracle.com/technology/deploy/security/database-security/howtos/eus-how-to.html
If you've done everything in the first doc...
Hope this answers your questions.

Oracle Database Mobile Server 11g

Hi,
We implemented Oracle EBS R11i for one of our customers. We also implemented Oracle Mobile Server 9i on Windows Server and Olite 9i on PDAs running Windows.
Now the customer wants to upgrade Oracle EBS to R12 and also upgrade Oracle Mobile Server and Olite 9i to newer versions of Oracle and also want to use Android on the PDAs/Mobile Devices.
Can we implement Oracle Database Mobile Server 11g and Mobile Client as mentioned in these links:
http://www.oracle.com/technetwork/products/database-mobile-server/dms-11g-datasheet-512117.pdf
http://www.oracle.com/technetwork/products/database-mobile-server/overview/index.html
I think it will be a new implementation of Oracle Database Mobile server and Mobile client and not an upgrade.
Any suggestions is welcome.
Regards,
Thiru

MFS embeds Olite into the product. Put another way, through MFS interfaces it defines/determines what functionality of mobile server can be used. Under the MFS configuration the Olite client database is used and the web-to-go app is used, there are no other choices. Very common when a software product includes some other product, it will determine what parts of the embedded product gets used.
Olite 10.3.0.3 as a separately download product used standalone has additional capability. Note: 10.3.0.3 is no longer separately downloadable over OTN.
In DMS 11.x -- we removed Olite client database, rearchitected sync to better fit BDB and allows for BDB and SQLite (either one of those can be used) on the client db. Again, MFS is only compatible with 10.3.0.3/2 right now. That team is a different development team within Oracle, on totally different release schedules than the Database Mobile Server development team. Android support was added in DMS 11.x.
thanks

Database locking using JSP and Oracle database

Dear All
I am reading about how to do database locking in general and i want to implement these mechanisms using JSP pages and oracle database, but i have the following questions:-
1.If i write a “select for update” quesry in the JSP page will it locks the record ? or it will not lock the record because the connection between the JSP pages and the server will be stateless in most online systems?
2.If i write all my jave code in transaction , something like this:-
• Begin transaction
• Commit or
• Rollback
Then should i be worried about the locking issues or the database manger will handle the locking mechanisms to insure data integrity(and what the default mechanism (if any) that the oracle database manger use to do the locking)?
3. If the answer for question 2 is no, then how can i handle the optimistic and the pentemistic locking using JSP pages?
BR

One way to solve this issue is as follows:
* You add a new column to each database table called 'version' which is of int type.
* Each time you alter any field in a record, you increament the version number.
* When you read a record and display it, you store the version number in your code
* when you go to update the record, you write your sql something like this:
update person set firstName=? where personId=? and version=?
Where the version is whatever you stored locally. If someone altered the record in the database while your
end user was looking at it, the version numbers will not match and the sql statement will
return zero as the number of records it altered. If its zero, inform the end user someone altered the record
while he was looking at it and weather or not he wants to proceed.
The chances of two people altering the same record in a table while both are logged in and viewing the same set of data is small so such collisions will be few.
You only need transactions if you are updating more than one record at a time (in the same table or multiple tables).
You dont need it for reading records if you use a single sql statement to read (for example: to join multiple tables).
In general, you get a (pooled) connection, use it, and close it as quickly as possible in a try/catch/finally block. You dont hold onto it for the duration of the user's session. A book on JDBC should help clarify this.

PDF Files in Oracle Database

First of all Hi and Thanks to All Respected Gurus of this forum for providing non-stop services to resolve problems on world-wide level.
I am using Oracle Database 11g-R1 with Oracle Application Express 4.1.
My clients (end-users) have the access to upload PDF files into database via an application built-in Oracle Application Express.
Suddenly ".dmp" size has been increased rapidly from 360 MB to 2.7 Gb and all it happened due to uploading of PDF Files.
I want to know is it alarming for Oracle Database? Because users have lot-of files to upload, so I am in doubt that will Oracle Database Services / Performance will be disturbed by increasing of database size or Oracle Database Server could be crashed?
Please confirm. Thanks in advance.
Regards: Muhammad Uzair Awan

Performance may be impacted.
Backup time would increase.
Backup space (Disk / Tape) requirements would increase.
There shouldn't be a "crash" of the database
Since you are running 11gR1, I presume that you are not running the Express Edition.

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.)
David

Logical model cannot refer to 'remote objects'?

Hi
Using DM 3.3.0.747.
In the relational model one can drag and drop in a table from another relational model from a separate design. This shows that table as a linked table and can be refreshed via the 'Synchronize Remote Objects' and allows that table to be referenced from your 'local' tables (i.e. used in foreign keys).
I tried the same, but for a logical model entity. This does not work/is not allowed? What is the expected behaviour?
We would like to use this for logical models as well. (So that we may develop/document the logical models separate, but use common/shared entities in the same way possible in relational models. This will help us a lot in keeping the models smaller and easier to manage and version control.)
Thank you & Regards

How to connect oracle database using DSN from jsp

hello, can any know how can i connect to[b] oracle database using DSN name from jsp .I am using oracle 9i and Tomcat 5
Using odbc tool i have created the dsn name but ithe connection does not make .here is the code that i have tried
Connection connection = null;
     try
          Class.forName("oracle.jdbc.driver.OracleDriver");
     catch(ClassNotFoundException Exception)
          out.println("error occoured during loading the driver ");
     try
          out.println("getting the connection");
          connection = DriverManager.getConnection("jdbc:oracle:deepak","scott","tiger");
          out.println("connection getted");
     catch(Exception exception1)
          out.println("error occoured ");
pls help as soon as possible
Sorry, for my english

you are actually using JDBC so the DSN entry does not matter.
2 things.
Make sure that your oracle database driver is in your classpath on your tomcat server.
I.E. copy the file classes12.jar into your common/lib folder of tomcat, or into your WEB-INF/lib folder of your application. and RESTART your server. classes12.jar can be found on the internet or more easily somewhere within your oracle installation. just search for it.
Make sure your jdbc url is correct. I believe it goes like this.... fill in the blacks
connection conn = DriverManager.getConnection("jdbc:oracle:thin:scott/tiger@MyOracleHost:1521:MyDB");Note how the username are passed in the first string there fore there is no need to pass additional parameters. This method may be depriciated, but if so, just take out the user and pass from the string and continue to pass them as 3 seperate strings.
connection conn = DriverManager.getConnection("jdbc:oracle:thin:MyOracleHost:1521:MyDB","scott","tiger");That should get your connection. if not, post your errors.

Cannot connect to Oracle database from SQL Server

Hi
We have set up a SQL Server linked server and tried to use this SQL Server linked server to connect to Oracle database. We are using SQL Server 2008 and Oracle client 11g 11.02.00.01. However, we got this error message:
Msg 7347, Level 16, State 1, Line 1
OLE DB provider 'OraOLEDB.Oracle' for linked server 'OurLinkedServer' returned data that does not match expected data length for column '[OraOLEDB.Oracle].Ourfieldname'. The (maximum) expected data length is 6, while the returned data length is 2.
We are able to connect some of the tables ok but some of the tables are not connected and got the above error message.
Any suggestions are greatly appreciated.
Thanks a lot
Tom

Hi
Here is more information. We just found out that the Oracle database team changed the character set to something else and then they changed it back to UTF8.
Currently, it is using UTF8 character set on the Oracle side. Will this causing us this error message on our sql server linked server?
The error message said "The (maximum) expected data length is 6, while the returned data length is 2."
This refers to a field/column with char(1)
Any suggestions are greatly appreciated
Thank you
Tom
