Question about integrated NEXT_RECORD and when-validate-point trigger

Hello

I work with a form that/did the following:

1) has two blocks of data (block 1 - & gt; Simple registration block & Block 2 - & gt; Block Record multi)
2) has few items in each block.
(3) when I filled the block 1 fields and press tab to navigate to next item key of an element in the trigger in block 1, block 2, I created a timer and when the period expires, the When-Timer-Expired trigger in the form of fires, which has a cursor that retrieves data from different database tables and assigns to the items in block 2 and saving the form must Save all records to the database tables attached to form blocks.

During this process when I open the cursor and assign values to each element and say NEXT_RECORD when-validate-point triggers written on each level elements fires and validations. The code looks like this.

Code of the trigger WHEN-TIMER-EXPIRED

DECLARE
CURSOR C1
IS
................
................
................
BEGIN
FOR c1_rec in C1
LOOP
: block2.item1: = c1_rec.col1;
: block2.item2: = c1_rec.col2;
: block2.item3: = c1_rec.col3;
message ("point value 3 is" |: block2.item3);

NEXT_RECORD;
END LOOP;

DELETE_RECORD;
POST;
PREMIER_ENREGISTREMENT;
END;


So my problem is the value assigned to: block.item3 before call NEXT_RECORD is away for WHEN-VALIDATE-ITEM trigger on the same element. I tried to print the value as soon as the trigger is activated. Assume that the previous value is "100" the WVI trigger value is printed with a NULL value.

I tried several times, but all the time, I get the same value.

Can someone help me identify the problem?

Thanks for your time and help

Your problem may be a timing problem caused by a trigger when-validate-order of the day on your null file at the end change your loop like this:

FOR c1_rec in C1 LOOP
  If :System.Record_status <> 'NEW' then
    Next_record;  --only advance if record is already populated
  End if;
  :block2.item1 := c1_rec.col1;
  :block2.item2 := c1_rec.col2;
  :block2.item3 := c1_rec.col3;
  message ('Value of item 3 is ' || :block2.item3 ||', Value in Col3='||c1_rec.col3);
  message(' ',no_acknowledge); --force above message to display immediately
END LOOP;
POST;

In addition, you must not use next-element key to start a clock. What happens if the user clicks on the element rather than the tab? You should start the timer of the trigger when-validate-record of the first block. It runs all focus time leaves the line of Block_1, unless a change has been made, and regardless of how the user leaves the line.

    I have a field called equip_code and some validations on the when-validate-item trigger that fills some years messages then opens a comment box. Next to this piece of code equip, I have a button for the list of values. If the user clicks the button (LOV), I have this code.

    If FORM_SUCCESS then
    do_key ('LIST_VALUES');
    end if;

    How can I force the trigger when-validate-point once the user chooses in a list of values.

    Next key element I have this code

    Validate (item_scope);
    If form_failure then
    raise form_trigger_failure;
    end if;
    do_key ('enter');

    I have this so that when-validate-item trigger before button-next. But when the user chooses in a list of values, I want to trigger when-validate-point. Any help appreciated.

    Your LOV button, in relaxation when button pressed, just do this:

    Go_item('MY_BLOCK.) EQUIP_CODE');
    If Form_Success then
    List_Values;
    End if;

    I don't think that anything on the trigger next-item key you need. If the equip_code value is changed, the WVI trigger runs when the focus (the slider) leaves the field.

    If you want to force the validation immediately once the user selects a value from the LOV, you can then change the List_Values; call over Do_key ('LIST_VALUES'); then create a trigger key-ListVal on the element. In the code, you d code: If Show_LOV ('MY_LOV') then Validate (Item_Scope);

    You must NOT put the code of validation in the trigger element next key, because it does not work if the user uses the mouse to click in a different field, or that he uses any number of other methods to leave the field.

  • return to the step after when-validate-point raise form_trigger_failure

    Sorry for this question but its a long time I had to program forms...

    I do validation step in a when-validate-point trigger. the trigger fires form_tirgger_failure on the validation point failure.

    is there an easy way to make the focus to the item once the failure is triggered?

    the most insight.

    You don't have to do anything. When form_tirgger_failure raised in when-validate-item, navigation fails and that the focus remains on the original item.
    Is it not what you see?

  • A few questions about integration between POET and EBS

    Hi you
    I am a new bie BIEE. In those days, have a look at the POET architecture and BIEE components. In the next project, there is some work on the development of POET based on request of the EBS. I have a few questions about integration:

    (1) generally, the POET application and database server is decentralized with application and database EBS? Both BIEE 10g and 11g version can be integrated with EBS R12?

    (2) in the POET administration tool, the first step is to create arrays of physics. If the source application is EBS, is it still necessary to create the physical tables?

    (3) if the physical creation of tables is needed, how to transfer data from the source of BSE BIEE physical tables tables? What ETL tool is preferred for most of developers? generator for warehouse or Oracle data integration?

    (4) during the data transfer phase, there are many many large data to transfer, how to keep the entire? for example, it must transfer 1 million lines of source to physical tables BIEE database, when 50% is completed, users try to open the POET report, they can see the new data of 50% on the reports? is there some transaction in phase control ETL?

    could someone give some pointers for me? I am very appreciated if you can also provide any other information.

    Thanks in advance.

    (1) generally, the POET application and database server is decentralized with application and database EBS? Both BIEE 10g and 11g version can be integrated with EBS R12?

    You shud look at OBI request here that uses OBIEE as a tool for reporting with pre-built modules. 10g & 11g comes with different versions of the applications of BI that supports sources such as Siebel CRM, EBS, Peoplesoft, JD Edwards, etc...

    (2) in the POET administration tool, the first step is to create arrays of physics. If the source application is EBS, is it still necessary to create the physical tables?

    His independent of any source. It comes to OBIEE modeling to create the RPD with all the layers. If you build from scratch, then you will need to create all layers else if BI Apps is used so you can get pre-built RPD and other pre-designed components.

    (3) if the physical creation of tables is needed, how to transfer data from the source of BSE BIEE physical tables tables? What ETL tool is preferred for most of developers? generator for warehouse or Oracle data integration?

    BI apps comes with ETL pre-built mapping to use with the tools majorly with Informatica. Only applications BI 7.9.5.2 comes with ODI, but oracle has the intention of having only ODI for any other versions.

    (4) during the data transfer phase, there are many many large data to transfer, how to keep the entire? for example, it must transfer 1 million lines of source to physical tables BIEE database, when 50% is completed, users try to open the POET report, they can see the new data of 50% on the reports? is there some transaction in phase control ETL?

    User will see still old data because its good enable Cache and serving it after each load.

  • A question about the methods and parameters.

    Hey guys, this is my first post here. I am very new to Java and done a bit of C++ before Java. I had a question about the methods and parameters. I do not understand the methods; I know they can be repeated when it is called, but it's almost everything. I also know that a program should have a class that contains the main method. What I really, really understand on methods is what the parameters are. I know they are in parentheses and that is it. Could you explain what they are? I really appreciate it. Thanks to all in advance. Best regards, Michael

    Taking an example:
    Suppose you calculate area of the rectangle you need two inputs one is the length and the width. Area = l X b, where l = length, b = width

    If your method, say, calculateAreaOfRectangle (length int, int width) will be two parameters as arguments.

    System.out.println ("field of rectangle:" + calculateAreaOfRectangle (40,30);)

    public int calculateAreaOfRectangle (int length, int width) {}
    int area;
    Area = length * width;
    return of area;
    }

    So if you call this method then the output will be returned in 120.

    Parameters of a method are simply the input variables for the method of treatment for all calculations or something useful.

    And we cannot have methods inside the main method in Java. It is in the java syntax and if you do, it will throw a syntax error.

  • Question about the interruptions and priming

    Hello

    I had a few questions about the startup and interruptions in a virtualized environment

    Assuming that, plenty of virtualization (no material assistance to virtualization of memory ).

    1 initialization: in an ordinary PC, the boot process starts with the BIOS, to expansion ROM, back to the BIOS and MBR secondary boot record, then grub (is it) and finally the operating system. In a virtualized environment with VMM running directly on top of hardware (Native VMM), how is the initialization of the different process, as I understand it takes BIOS-> Expansion ROM - > BIOS-MBR-> other record secondary-> VMM-> OS--> applications >. Am I right on that?

    2 breaks: VMM examines the source interruptions prior to the interruption, so in a multicore environment, assuming a 2 processor core, how the VMM decides on the kernel for which the interruption in intended, prior to shipment of the interruption. Interruptions are tag ID, said core ID?

    Thanks in advance

Am I right on that?

    It is simplistic but essentially correct.  A metaphor would be a little better thinking that the hypervisor/vmm is an operating system, except that the process on this operating system are requests or comments OSes.  If the BIOS-> OPROM-> BIOS-> MBR-> hypervisor-> init process of the hypervisor-> reviews of fork () s operating systems.  This can become blurred by the design choices (for example Xen/Hyper-V init start a coded parent hard partition that makes hypercalls privileged to fork() guest OSes; ESXi init runs a very limited subset of applications directly on the hypervisor and ESX Classic is somewhere between these approaches).

    There is a subtle distinction between "hypervisor" and "www."  The "hypervisor" is the operating system of single root (e.g. ESX) who interacts directly with the hardware and has access to everything; a hypervisor is not to be used to run virtual machines.  When we talk about a "hypervisor", the tendency is to describe something which is a BONE (although usually a minimal OS designed only to run virtual machines).  The "www" is the layer that allows a virtual machine run: it provides the interposition, virtualization and emulation services and can be plural (for example a vmm by guest operating system).  Architecture of VMware deal with these two separate components, while most other virtualization platforms merge the two.

    Strictly speaking, the interruption is not transmitted to a guest operating system - receives the hypervisor (or rather the VMM it transmits to the hypervisor), the hypervisor drivers interpret the interruption (for example reading package of NIC, I/O process of HBA, the timer tick completion), then after a new appropriate break in the guest OS.

  • When-validate-point shot F10?

    In Forms6i, there is a block with data element two, itemA and itemB. I have a when-validate-Item trigger on itemA:

    If: itemA = 0 and: itemB > 0 then
    raise form_trigger_failure;
    end if;

    If I enter 0 itemA and itemB (current position of the slider on itemB) 5 and press F10, Oracle stores data. I don't want to save data if no trigger of W-V-I is not correct.

    -J' have set unit (property) of Validation at the point
    -KEY to ENGAGE on the level of form is:
    BEGIN
    Enter;
    IF this is Form_Success THEN
    RAISE Form_Trigger_Failure;
    END IF;
    IF: System.Form_Status = "MODIFIED" THEN
    Commit_Form;
    IF: System.Form_Status <>"QUERY" THEN
    Message ('error!');
    Bell;
    RAISE Form_Trigger_Failure;
    END IF;
    END IF;
    END;

    Can someone tell me what is the problem? Why forms commit data if one of the W-V-I is not ok?

    Have you done these steps?

    Enter 0 in itemA. -> WVI - lights and does not raise no exception for itemB is null
    Enter itemB 5. -> No WVI-trigger on this point, so no need for validation.
    Now your file is valid, that there will be no more validation, so the form will record data.

    You must either add an additional trigger WVI to the itemB, or create a WHEN-VALIDATE-RECORD-trigger block to do the validation.

  • Go_Item not available in a when-validate-Item trigger function

    Hello. I find that I can't use the Go_Item function in a trigger when-validate-point because it's a small trigger. Is there a common method to pull a trigger that I can use to validate an element (similar to the trigger when-validate-point) is not restricted to where I can use built-ins such as Go_Item, Go_Block, etc... I would use the trigger next-item key, but it does not when a user mouse clicks outside of the question, I need to validate.

    I need to get a validation on an element that identifies if some values were seized. If I find some values, so I need navigate a block "Diary problems" where the user can complete a problem. After leaving the block "Issues Log" I need then to return to the previous box and allow the user continue to enter items. This navigation appear to be limited in the when-validate-Item trigger.

    Any help would be greatly appreciated.

    Yes as Frane explained to create a timer and the fire on WHEN-VALIDATE-item and it expires after your operation as workaround

    or at the level of the blocks ONCE - NEW - ITEM - INSTANCE, you can write something similar

      if :system.trigger_item = 'MYBLOCK.MYITEM' then
             Your code
     end if;

  • Values to change due When-validate-item trigger

    Hello

    I develop a Form6i. I have a lov client_name field. I have a when-validate-item trigger for the customer name field.
    When I select the cutomer_name I have other fields who shoot according to the client_name as payment_term, Sales_rep, price list and so on.

    The question I have is Ex:

    When I select client_name = "ABCD". Field of payment term will be driven using the code of a trigger when_validate_item and complete payment limit = 45 Net.
    When I change the payment term is Net 30 and save the form, it will return to Net 45 and saves.
    I know it's because when-validate-trigger fire again at the form level.

    I want to change the payment_term to change only when client_name y change. Like the same functionality as Oracle, order entry

    How do I have more to come, can someone help please.

    Thank you.

    and in the when-timer-expired in the block of the form:

    go_block ('cxs');
