Location of database as part of the ADF

Hello

I have a new framework of the ADF. I use JDeveloper 12.1.3.

Here what intrigees me. I understand that when I use the view onlu-reading, my data object (I pulled from the database) are stored in all lines, and I can access it through the iterator.

But here's what I don't understand. When I use entity based in view, and I pull some data from data base, where it is stored? In Instance of EntityObject based my opinion or elsewhere?

Thx a lot

Reverse - VO is always store the current version of the line, with all the changes.  Or a new line that was added.  Or will be missing a line that has been deleted.  EO is to store the data needed to make these changes, until a commit or rollback is issued.

Now I'll betray my ignorance - I don't know if EO is to store the original line.  If I'm not mistaken, a restore requires a re - interview, and that's how the VO is set with the latest data from the database.  But I'm ready for someone to put me straight.

  • Move the database as part of the Oracle 12 c upgrade files

    Hello

    I read the document upgrade Oracle for the database Oracle 12 c.

    http://docs.Oracle.com/CD/E16655_01/server.121/e17642/upgrade.htm#CHDJJJEE

    Here in DBUA, step 8 says that

    Move database files in the page, select an option:

    • Move database as part of the upgrade files
    • Move the quick recovery as part of the upgrade area

    I wonder why we never need to use this feature to move database files?

    I understand for FRA, it will define just the parameters DB_RECOVERY_FILE_DEST and DB_RECOVERY_FILE_DEST_SIZE parameters to initialize at the new location and size new startup of the new home of Oracle database. But why never use us animated here database files option?

    I created query view object based on the master and two poll objects of the base seen as details. Then, I created two master of first child link and another link for master of the second child. Even in this case in my data controls I see two different components which is incorrect.

    -Orange [SECOND CHILD]

  • View database do not update the ADF application

    Greetings,

    IM facing a weird problem in my application (11.1.2.4.0 - ADF JDeveloper). All this time I was working directly with tables (VO), but now I also started to use database views.

    Everything works fine, when I add a new row in a table that is associated with my point of view of database it refresh properly.

    BUT if I manually remove lines of my database, the view is not updated in my application, not by refreshing the page.

    redeploy the application, execution of the query of the view inside the view object object. The only way to display the DB to be

    update inside the JDeveloper and at the time of deployment is to restart JDeveloper. I try to add an action on my OV of the re - run when

    I do something in particular, I hope that will reset the cache and retrieve the view DB again, but without success...

    Fixed: now, it's not yet update on restart jdeveloper.

    Just for accuracy, I'm talking about database views, and not only opposing views. I create a view of the object inside the application to retrieve data

    According to the results of the database view.

    Can you help me on this please?

    Yes the queries in SQLDeveloper showed me the correct results.

    But I am disappointed... When I went to close SQLDeveloper to try something, it me pop a message to change commit / rollback.

    After I commit to them, my app show too many correct results.

  • Inserting a new record in the database using a form empty ADF

    Hello

    I'm trying to insert a new record into the database using a form.

    I have an Employee table and its corresponding entity object and the view object. The table has an id that is used as the primary key and is filled using a sequence in the comic book.

    Data controls, I dragged and dropped at the sight of the employee as a form of ADF and checked the submit button include. Then I dragged and dropped the validation on submit button operation.

    When I connect to the app and go to the page used to create, I have 2 problems:
    1 - the form is filled with the logged in user info.
    2. If I try to change the news and validation, the user info is changed in the database and no new record is created.

    It makes a little sense to me, but I would like to know if there is a way around it (get an empty form and insert a new record).
    NB: the employee id is not part of the form, I want to be filled using the sequence.

    Kind regards
    MB

    User, please tell us your jdev version!

    To do this, you must create a new record before going to the display of the form page. In a stubborn workflow (btf), you drag the operation createInsert of the VO on the btf and it will generate a link method, add a view to the btf and put a navigation of the binding of the method of the page. Mark the method as 'Activity by default'. Now, ren, you call the workflow, you create a new record that will show your blank form.

  • Question about the ADF Version supported Oracle database

    Hello

    One of my client's situation trigger this thread, they have a few Oracle 9.2.0.6 inherited instance, which turns out to be that a version of database not supported for JDeveloper/ADF 12.1.3, in this case, supports an earlier version of the ADF is the only choice without upgrading of database to 11.x for them?

    And I'm also interested to know why JDeveloper/ADF confined its support to some version of database Oracle, thank you

    -Liang Yi

    Hello

    If I'm not wrong then the Oracle 9i database is out of support since juil.-2007. JDeveloper and ADF certifies and supports the unsupported database versions or operating systems. So I hope that answers the "why". The real solution is to upgrade the database, because that's the reason that will block you for what your client is to move forward.

  • How to better manage the ADF database connections

    Hello

    We got our DB connection configured as service JNDI in weblogic server and used in many features where we depend on EO / VO concept completely.

    Now, we need the customer that each connection from the pool must call a DB procedure first as below before you run the linked application SQL or anything:

    DBMS_SESSION.setIndentifier ("< app_user_id >" ");

    When you pull custom SQL, I guess that's pretty simple to do, but when it comes to EO/VO where ADF supports DB calls, we don't know how effectively...
    Can someone help how to achieve this?

    -Thanks a lot

  • Correct location for the ADF - settings.xml?

    What is the correct location for the adf ADF - settings.xml in JDev 11 g applications file? Documentation conflicted says:

    (1) as by Frank & Lynn Oracle Fusion Developer Guide pg 92, it appears in the correct location for the ADF - settings.xml is < workspace >/.adf/META - INF.

    (2) according to the ADF Web Guide, it seems, it must be < workspace > / < project > / META-INF: http://download.oracle.com/docs/cd/E14571_01/web.1111/b31973/ap_config.htm#BABCBJAB

    Which is correct? With our thanks,

    DMI

    Chris,

    the recommendation to create the ADF - settings.xml in the project source META-INF directory solves the problem of two projects to be used in a single workspace. If the two projects use ADFc MDS got confused. Notes version in R1 mentioned as follows:

    If your J2EE ADF (EAR) application contains several modules web application (WAR files) and contains more than one ADF task flows, then you can get unexpected behavior due to the web application using another its flow XML file with the same name of task (the problem is more likely to occur with the adfc config.xml file because each web application has usually one). You can avoid this problem by defining a 'root web application' separate for each web application (WAR). Web application at most one cannot have any parameters of root web app. To set the "web app root" for an application, you must add an XML file called META-INF/adf - settings.xml to WAR under WEB-INF/classes with content as follows:

    +
    xmlns:WAP = "http://xmlns.oracle.com/adf/share/http/config" >
    ++
    ++
    +
    +
    ++

    The value of the rootName attribute can be any name that uniquely identifies the web application (war) within the overall application (ear).

    In JDeveloper, the new file can be added as follows:

    + 1. Expand the web application project in the browser Application.
    + 2. Right-click on "Sources of the Application", and then select the item 'new ' +.
    + 3. Select "XML Document" and click OK.
    + 4. Type "adf - settings.xml ' under the file name +.
    + 5. Click on the "Browse" button, select the source directory of the project, click the iconic button "Create a new subdirectory" at the top right, type "META-INF" directory name and click OK, then click Select.
    + 6. You should now have a directory and file name "adf - settings.xml ' name '/META-INF +.
    + 7. Click OK to create the new file.
    + 8. In the Source Editor, paste in the XML file above and put a value appropriate for the rootName attribute (this is known as the parameter 'root web application').
    + 9. Make sure that the deployment for the Web application profile includes the new file META-INF/adf - settings.xml under WEB - INF / classes.

    So, if your application has a single web project then this configuration as documented in the book is good to use. To avoid the problem described above (which is in response to bug 8395585) you set it in the project's source. Note that adding adf - setting.xml in the project was presented as a work-around. The bug is closed with a fixed rate per 11.1.1.2, which means that, since the PS2 there should be no need to store the ADF - settings.xml in the source of the project more.

    So long answer that leads to a simple answer: the book is good and the documentation lists always bypass it. However, I'll fill a bug against documentation and make report understand (do not have the time to check the issue being fixed)

  • With the help of connections to database for the safety of the ADF

    Hi all

    I have a request of 11g ADF (11.1.1.2.0) that uses the security of ADF and authenticate via LDAP against an Oracle Internet Directory. Now, we have an obligation to authenticate Oracle database users and remove the need to use the OID. Is it possible to do this in WebLogic?

    I know that if I maintain my own tables with user name and password in the form of columns, I use a SQLAuthenticator as described here:
    http://Biemond.blogspot.com/2008/12/using-database-tables-as-authentication.html

    But in my case I don't have my own table 'users', I actually want to use RDBMS users (just like Oracle Forms only). Has anyone written an authenticator class that can do this?

    See you soon

    Hello

    Oracle Forms keeps a user login to the database schema - so it performs no authentication. If you want the personal connection, then security ADF isn't the riht place to look for that but referrals under ADF BC dynamic JDBC

    To perform authentication against the schema of a database without connecting to the application to it (only for authentication pupose), you will need to write a provider of custom authentication (a JAAS login Module) for WLS wrapped. Then, this can be configured using the WLS console and authenticate the user session. This can then be used to authenticate the security of the ADF. See the documentation for WLS for how to write custom authentication providers
