What is good practice to update fields of VO on the user action

Hi all

version: Jdeveloper: 11.1.2.1.0

I have an obligation to update some fields in VO (such as status, date of approval) to the "Approve" button is clicked, I want to know what the good practice of VO update in this case because I see two options for me here.

1 1 manipuler handle in a managed bean, get the iterator VO and to update the VO and invoke the validation operation.
2. write a method in AM and get the VO, update the attributes of the vo and call commit transaction db.

Can anyone suggest what is good practice in this case?

Kind regards
Delighted Nuka.

How about a combination of the two?
The requirement is a requirement of the company, the method must be implemented in the model. Use a method in the vo or am for her. This method you expose on the customer interface and then call through the layer, just like you call create method error. After you call the method commit the bean or no later than the point in your workflow.
You should not call commit inside the method as method then can be part of a larger transaction.

  • BUG: Windows Update, a negative impact on the user.

    This is the second time I had this problem, but this time I thought what is the problem.

    When Windows Update installs an update and requests that restart the computer and you can report up to four hours. The problem is, it ignores completely any request to postpone until after the first. If you select 4 hours, then 3 hours later tell him to postpone once again for 4 more, it will still restart regardless of your desire, an hour later.

    I entered things immediately when windows starts, and this glitch cost me an important download and data from two programs I've been multitasking since he ignored my requests - it wasn't just the right time to restart because of downloading and other circumstances. It is completely unacceptable that the windows to take it upon itself to restart without asking directly for the user. In a second window 3, I lost everything I work on and watched the "Windows applies an update" etc screen, then moments later it restarted.

    I had recently extended the restart, because I knew I'd be able to finish in the next 20 minutes or so. Either do take into account further postpone requests or if you carelessly ignore the desire of the user, generate a warning saying Windows PINGING in x minutes. Please save your work. I had no warning. Just bam, restart. Data of bye bye.

    So change "download updates up-to-date, but... "option then do not approve the installation of ANY updates unless you are ready to restart.

    Otherwise, WYSIWYG.

    PS: Do not forget this part:


    Related to security updates, your computer is dangerous before this restart occurs: it is vulnerable to attacks that exploit the problem has been corrected by the update that requires a restart.

    If the update requires a restart before your computer protected, why install if you are not ready to restart?

    Is there a way to insert a form field in an AcroForm which allow users of Reader to browse and insert an image in this form field?

    I know that LiveCycle can do, but I need to do using an AcroForm. Or maybe there is a third party plug-in that can be used in an AcroForm to do this?

    No, you don't need 11 Acrobat to create a form that uses this method, but your Reader users will have to upgrade. I don't see that they have yet to announce the date output to drive, but in the past, it was usually in about a month of the announcement.

  • Normal reboot a server DB is a good practice?

    Hi all

    Recently, I hit a bug "Bug 10194190 - Solaris: spin process and/or ASM and DB crash if RAC instance > 248 days ( Doc ID 10194190.8 )" "

    One solution is to restart the Server DB regularly.

    I would like to know if control restart a server DB is a good practice in a normal case without hitting the bug.

    In my experience, Unix platform is more stable than the Windows platform in

    end of time. Truth without papers we need to restart Windows

    Server for the services included in some cases.

    I heard not to restart a database regularly in the Unix platform.

    To my knowledge, a 7 x 24 reviews should have as more long availability possible.

    However, I share that a database must be restarted in some cases as

    patching and some other maintenance.

    In our case, I agree that we must take this workaround solution, restart regularly the DB server, to

    the problem at this point. However, I want to know, as a good practice, if a DB server must be restarted on a regular basis in the

    normal case without hitting the bug.

    Maybe a need to define "regular". To my knowledge, the bounce is not good because it has continuous setting on in the background, which is reset every rebound in memory. I am referring to the tuning that is associated with the presence of the SPFILE.

    I don't know how long it takes before this system is on the right track, it's an interesting question.

    But rebounding is good, because ultimately you will need a few days. Nothing like a test procedure and bounce a database is one procedure like the others.

    Obviously, 24/7 databases are a reality, which makes this exercise very difficult/impossible.

    Not many problems will be solved with bounce data well. But if a problem appears as it does, it is not impossible. I saw only once (on a Unix system). In the end, no one was able to explain the cause, and bounce was unsalted solution. The dirty fix was: kill the production process. And the problem disappeared with the upgrade (11g). Just a fact.

  • What does the Create action not?

    Hello

    I use JDeveloper 10.1.3.4 and you have questions about the action Create {color} {color: blue}.

    I have a data table named USERS and a corresponding VO in the data control palette. Drag and drop the original Version of users to the page as a table with the column of enabled selection, I let the user be able both to delete a selected line and create a new line.

    I'm new to this, but for deletion, there is no problem: drag the delete action under the control of data users VO and drop it into the table {color: green} > table facets > Selection > af:tableSelectOne - Select and node {color}, then drop the request module commit an act on the page also as a commandButton control. And the selected line can be deleted and committed deletion using these two new buttons.

    Similarly, I dragged the action Create {color} {color: blue} and he fell in the table {color: green} > table facets > footer node {color} like a command button. When the page is running, nothing is visibly when you click on the button create {color} of {color: blue}. I understand that you do not select a line to create a new line, so I did not put the button create in the same node with the button Delete. And I guess I'll have to create a separate page for the user to enter the values in the fields on the line must be created.

    What I want to know, what's this button with the action {color: blue} create {color} inside is different than a generic commandButton created from the ADF Faces Core > commandButton? If I create a commandButton control in the component palette that is empty inside. But by using the action of creation as a commandButton control, is not yet clear to me that creating would make the action inside the key. On the other hand, there must be a reason for the {color: blue} action Create {color} be there slot that VO in the range of control data for us to use. What is the reason? And that makes the action Create {color} {color: Blue}?

    Thanks for answering my question!


    Newman

    Hello Newman,

    If you want your new line to be available in the whole of current lines (for example to edit directly in the table, not on a form), then take a look on the CreateInsert operation. Otherwise, you need a form to edit the new line.

    Check out these links:

    What I want to know is how this button with the create action that it is different than a generic commandButton created from the ADF Faces Core > commandButton?

    When you create a button for the create action, your page links are configured automatically, then a link to action to create a to-do from the iterator is added to your pageDef (and this iterator is bound to your view object).

    And what is the Create action not?

    The create action creates a new line but does not insert it in the whole of lines.

  • What is a good practice to manage LOV in jdev apps?

    Hi, experts,
    In jdev 11.1.2.3,.

    In our projects, there are numerous LOVs whose value are stored in a common dictionary table, for example in the refcode table:
    refcode (id, low_value, high_value, sense, domain_no),
    Different LOVs can extract value peers (low_value, meaning), or (high_value, sense) refcode table by using domain_no as the filter criteria.

    In the user interface of the user, the values of field/code number should be displayed by a sense of refcode password
    To achieve this, I'll create many links between the different tables with refcode,
    and create your entity refcode consider the secondary entity views.

    I feel some odd (because so many associations with the same table refcode),
    What is a good practice to manage LOV in this way?

    Thank you.

  • Good practices of FIFO: updated old cluster or create new

    Hello world

    My question is more on "good practices" that really solve a problem.

    I use FIFO to send images and other data from a producer to a consumer.

    I created a cluster which includes all the data that must be sent through the FIFO.

    My question is: can I create a new cluster to each loop of the producer and put this cluster in the FIFO or should I set a shift and then register and update the data of this fallen registry change by sending in the FIFO?

    Below you will find two screenshots that sums up the idea (NB: these aren't the real VI.) We come here to show the general idea).

    If there is a difference (in the way that the computer uses memory for example, or something else...) between these two methods of programming, you will give me some details so that I can understand why to use one over the other, please?

    Thank you very much.

    Best regards.

    Luke

    I think that there is very little difference in terms of performance (perhaps the registry approach change is slower than sliiightly - but probably not noticeable in most cases).

    The main reason you want to use the shift register approach is that if you update only certain values before sending the data in the queue, those that would be lost if you created a new cluster each time. For example, if 'Directories' was constant, you could just power/updating that once the value to the registry to shift and just update the part "ImageAcquired" of the cluster before you send it in the queue. This also means that if you update your cluster to have more elements (using a type-def, of course), you can be less worried about having to update the individual elements.

    I think it is less a problem of performance (both are valid and effective) and more a matter of maintainability and flexibility.

  • Update field of auto-increment using ASP.

    I use Dreamweaver 3 and created dynamic arrays using the tools ASP. I met a wall:

    When you create a form to a form, how to configure the form to update an Auto-Increment field in Access?

    I have what I think is a good book on Dreamweaver, but this feature is not discussed. If I omit the field of

    the form, he leaves the null field and I get a database error, as I expect.

    Any help or documentation links will be appreciated.

    Joe

    As others have said, the database must manage this area and it shouldn't appear on the form on the page in code that performs the actual insertion or update.

    Do you a little differently depending on whether you use the wizard insert or create the form by hand and then apply the server behavior insert.

    If you use the wizard when you select the fields in the form, make sure that you click the auto increment field, and then click the icon 'less', this it will remove the form and it will not appear in the code generated automatically, leaving MS Access free to manipulate himself.

    If you create the form by hand, do not include a form for the field to auto-increment element, then when you apply the Insert behavior it will not appear in the code generated automatically, leaving MS Access free to deal with himself.
