• vs 10g 11g: VO bind variable values stale on jbo.ampool.doampooling = false

  Hi gang
  
  (JDev 11g Build 5188)
  
  I'm currently such tests recommended by the merger of 11g Guide to test the management of State ADF BC with jbo.ampool.doampooling = false (see paragraphs 36 and 37). I see different behaviors under 11 g vs 10 g.
  
  I have a single VO updateable with a query that is limited by a single binding variable. I have a JSF page with the link as command inputText variable, executeWithParams one operating control commandButton, and a table showing the results of the VO.
  
  Less than 10g, I can:
  
  (1) open the page
  (2) enter a value (say X) to the variable binding, click the executeWithParams button and correctly to see results in the table corresponding to the value of the bind variable X.
  (3) enter a different value for the binding variable (say Y), click on the executeWithParams button and correctly to see results in the table corresponding to the value of the value of the bind variable Y.
  
  Less than 11g I get different behaviors for # 3. Instead when I press the button executeWithParams with the value defined on, the table always show results for the previous value of the variable X bind?
  
  It should be noted that if I set jbo.ampool.doampooling = true, the problem goes away, but probably the error reappears in a system of production under load, so I need to find what is happening here.
  
  Maybe I see a bug, but given the large amount of changes 11 g and large amount of documents that I read on the management of the State, it could just be that I missed something vital to 11 g.
  
  Does anyone have any opinions, what is happening here?
  
  Thank you for your help in advance.

• Problem in setting style during execution by using setStyle?

  In most tutorials for FLEX, I find affecting components Runtime Style is a problem

  Can someone please let me know what's at stake if we set the style in the runtime help by calling setStyle

  Thanks in advnace.

  Hi Kiran,

  Call the setStyle() method can result in reduced performance. Use it only when absolutely necessary.
  You should try to apply style sheets rather than using the setStyle() method because it is expensive. This method should only be used when you change styles an object during execution.
  You cannot get or set the style properties directly on a component that you can with other properties. Instead, you set the properties of style at run time by using ActionScript getStyle() and setStyle() methods.

  Hope this will make things clear...

  Thank you

• Disable the extended FIFO FPGA target during execution

  Hello

  I use a FIFO extended target in my FPGA to constantly calculate the derivative of a measured value (dB/dt). Thus the FIFO stores all values during time dt. This means dt determines the number of items in the FIFO and dB is determined by the actual value less the oldest value in the FIFO. It works well when I initialize with the code in figure InitFIFO.

  But the FIFO of compensation is not possible (see figure clearFIFO). In the while loop if "reset dB" is false, as the new value of B is written on the FIFO, then the oldest value is read from, for the number of items in the FIFO remain constant. To change dt during execution, I need to clear the FIFO and initialize it with a new length (number of items). I tried the next loop, but it does not work. The FIFO does not initilized with the elements. The length is zero and the loop counter for (#deltaB Length2) is 0.

  What I am doing wrong? Is there a better way to erase a FIFO during execution in the FPGA? I'm now stuck for 2 days with this problem and looking forward to any idea or suggestion.

  Thank you very much. Best regards

  Andy

  Hej,

  Thank you for your response. You were correct, that deltab FIFO length was 0 because the defalt value was zero. The problem is that in my host vi on the RT system I put DeltaB FIFO length in a loop of high priority and as you can see when I restart the FPGA, DeltaB FIFO length has a valid value (the code in figure 1 works well with a local variable of DeltaB FIFO length in the FPGA). But the variable to set the variable "reset dB" is under the control of the loop of low priority of the host vi. And there, I had an entry DeltaB FIFO length unwired.

  So, I learned that a control FPGA read/write unwired sends a '0' or resets the variable to its default value in the FPGA. I assumed that nothing is transferred and the last variable is retained if you let a control read/write unwired. Now, I learned of this stupid error!

  Thanks a lot again!

• ADF BC: default jbo.ampool.maxpoolsize

  Hello
  
  The "Guide of Oracle® Application Development Framework Developer for developers of forms/4GL 10 g Release 3 (10.1.3.0) B25947-01" has a Table 29-2, 'Parameters of Configuration Application Module pool sizing', which says for jbo.ampool.maxpoolsize'the default value is 5000 cases.'.»
  
  I used JDeveloper 10.1.3.4.0 to create a sample application for the default value of jbo.ampool.maxpoolsize.
  See http://www.consideringred.com/files/oracle/2010/MaxpoolsizeDefaultApp-v0.01.zip
  
  It has a module of application with code like this:

  public class ScottServiceImpl
       extends ApplicationModuleImpl
       implements ScottService
  {
  //...
       public void printMaxpoolsizeValues()
       {
            System.out.println("ScottServiceImpl.printMaxpoolsizeValues() : begin");
            System.out.println("AMPOOL_MAX_POOL_SIZE_DEFAULT = "
                 + PropertyConstants.AMPOOL_MAX_POOL_SIZE_DEFAULT);
            System.out.println("System " + PropertyConstants.ENV_AMPOOL_MAX_POOL_SIZE
                 + " = " + System.getProperty(PropertyConstants.ENV_AMPOOL_MAX_POOL_SIZE));
            System.out.println("PropertyMetadata.ENV_AMPOOL_MAX_POOL_SIZE"
                 + " : getName() = " + PropertyMetadata.ENV_AMPOOL_MAX_POOL_SIZE.getName()
                 + " : getDefault() = " + PropertyMetadata.ENV_AMPOOL_MAX_POOL_SIZE.getDefault());
            System.out.println("JboEnvUtil = " + JboEnvUtil.getProperty(
                 PropertyMetadata.ENV_AMPOOL_MAX_POOL_SIZE.getName()));
            System.out.println("JboEnvUtil with default = " + JboEnvUtil.getProperty(
                 PropertyMetadata.ENV_AMPOOL_MAX_POOL_SIZE.getName(),
                 PropertyMetadata.ENV_AMPOOL_MAX_POOL_SIZE.getDefault()));
            Hashtable vEnvironment = getSession().getEnvironment();
            System.out.println("session environment = " + vEnvironment.get(
                 PropertyMetadata.ENV_AMPOOL_MAX_POOL_SIZE.getName()));
            ApplicationPool vApplicationPool = getApplicationPool(
                 "maxpoolsizedefault.model.ScottServiceLocal");
            Hashtable vAPEnvironment = vApplicationPool.getEnvironment();
            System.out.println("ApplicationPool environment = " + vAPEnvironment.get(
                 PropertyMetadata.ENV_AMPOOL_MAX_POOL_SIZE.getName()));
            System.out.println("vApplicationPool.getMaxPoolSize() = "
                 + vApplicationPool.getMaxPoolSize());
            System.out.println("ScottServiceImpl.printMaxpoolsizeValues() : end");
       }
  //...
  }

  The result in the Panel Log in JDeveloper is like this:

  ScottServiceImpl.printMaxpoolsizeValues() : begin
  AMPOOL_MAX_POOL_SIZE_DEFAULT = 2147483647
  System jbo.ampool.maxpoolsize = null
  PropertyMetadata.ENV_AMPOOL_MAX_POOL_SIZE : getName() = jbo.ampool.maxpoolsize : getDefault() = 2147483647
  JboEnvUtil = 2147483647
  JboEnvUtil with default = 2147483647
  session environment = null
  ApplicationPool environment = null
  vApplicationPool.getMaxPoolSize() = 2147483647
  ScottServiceImpl.printMaxpoolsizeValues() : end

  question:
  (q1) What is the value default real to jbo.ampool.maxpoolsize, 5000 or 2147483647, or something else?
  
  (Note that this example shows a small part of the confusion that can occur during execution, which requires improvement 7540624, 'need an API to access the runtime property values', mentioned in Re: [Poll] what are the 3 top improvements you want to see in JDeveloper.)
  
  Thank you very much

  In 10.1.3.x, the default value is the large number of that show you.

  In 11.1.1.2.0, the default value is 4096

• masking steps during execution

  I have a sous-suite that I point the user to when asked to isolate a card failure.  To give them some flexibility, I got a popup that gives them a certain number of options (see attachment).  I have an m.o. that indicates the individual steps these select/run (i.e. '1' or '3' in the png).  Control flow (denoted by '2') is the noise they don't really need to worry and may / will cause confusion (and possibly problems for me if they select them accidentally).  Is there a way to hide these measures flow during execution control so that the user sees '1' and '2' (and other similar 'valid' selections?

  If there wasn't a need explicit to have the flow control logic, then I'd be tempted to compact all in the post of the Popup Message action.

  

  By setting the Popup Message Action to go to the step, , use Custom Condition (TRUE):

  

  And by using the following Expression:

  Step.Result.ButtonHit == 1? RunState.Sequence.Main ["MR_RPack_R55"]. UniqueStepId:
  
  Step.Result.ButtonHit == 2? "" "RunState.Sequence.Main ["End_PCI_Isolation"]." UniqueStepId:
  
  Step.Result.ButtonHit is 3? RunState.Sequence.Main ["MR_R103"]. UniqueStepId:
  
  Step.Result.ButtonHit is 4? "" "RunState.Sequence.Main ["PCI_Intf_PT"]." UniqueStepId: «»

  It should be appropriate level following the Popup Message.

  (SequenceFile attached).

  I hope this helps.

• How to change the frequency of sampling DAQmx during execution?

  Hello guys. I'm using LabVIEW in the measures of the frequency response function. My application requires the sampling rate to change according to the frequency of the signal during execution.

  I tried to do it with a "structure of the event" and it works well when I change the rate manually via the front control but it backs do not work when I set up the sampling frequency to vary automatically (just a frequency sweep). Photos below:

  Why not the structure of the event feels the change in the value of "rate"?

  Thanks in advance for your help.

  Lucas

  Hello

  In "automatic mode" to change the sampling rate, the calculated rate is written in the local variable (as illustrated in the code).  Structure of the event does not change value in the local variable as an event.

  In order to make the structure of the event to recognize the change in value of an indicator such as event: write the new value to the property "Value (Sgnl)" corrosponding node to rate indicator (see figure below).  This will make the structure of the event accept the value change in the indicator as event.

  Note: Use architectures such as producers and consumers for such applications, which makes the application readable and expandable.

  See rear queries if any.

  

• Change the value of a Boolean switch rocker during execution

  Hello world

  Is it possible to change the value of a switch to toggle Boolean during execution?

  I make a program where the user can switch a relay switch.  However, I want the program to replace the user input if a measured value exceeds a predefined threshold.

  The program below did almost what I want.  The major problem is that it if the measured value returns below the threshold, the relay will be awarded if the switch is set to 'true '.

  

  I would be very grateful for any suggestions to solve this problem!

• ImageViewer BackColor property during execution

  Hello

  I use IMAQ Vision Development mould 2010 with VS 2010.  I have observed that the backcolor property is not active when running, even if it can be modified at design time.

  Is this a bug? I also observed that the pallet type is not changed to r untime.

  

  Any help is appreciated.

  There is a property called fill Image box Style you need to set solid rather than default.  Then you should be able to change color during execution.  If you have a default value, it you cannot change color.  Sorry I forgot that you use Visual Studio.  Even if I'm using LabVIEW, you should be able to do the same thing in Visual Studio, just put these two properties.

  * Edit: Just a quick note, it is not necessary for me to use a property node explicitly linked here.

  I hope this helps!

  

• Filter the Table during execution and keep uncommitted line changes

  Hello

  I have a requirement which has been quite difficult for me so far.

  I use the first version Jdev 12 c.

  I have a table of AF that is connected to a ViewObject that is used for sending new data.

  When I add lines to this ViewObject, I put a field that I intend to use for filtering so that the number of lines is not displayed at the same time.  This field comes from a selection of LOV.

  I want to be able to change lines are displayed in the table based on what is the current value of selection LOV.  This isn't a problem for me, and it works perfectly using a view criteria and a variable transitional EO I put in place.

  My problem is that when I select a new value in the LOV and change to bind the variable view criteria, I want all changes uncommitted to the lines to be preserved in the View object.  Currently, the lines are not keep their changes, and I need to do this, because after that the user has entered data for a large number of lines, there will be a commit to the database for all new lines added.  Is this possible or should I look for an alternative?

  I also tried to use a table filter in the link of the page layer, but I get an error that I can't debug. It is marked as Houston-34014.  In this method, I try to access my bean in pageFlowScope to filter the table.  This bean variable is updated when the LOV selection changes.  Error messages settings are {0 = oracle.jbo.Key [-220-225], 1 = root}.  I also read that this filter parameter is a static filter and does not dynamically during execution.

  Any help would be appreciated, thanks for reading.

• How to hide the ADF table during execution

  Hi all

  I use Jdeveloper - 11.1.2.4.39.64.36.1 version

  Is it possible to show only the tables with associated in the same lines and hide tables with no record.

  For ex: Let's say that at the time of the design, there are three related data tables with the diagram below.

  Table 1

  Table 2

  Table 3

  However, during execution, there is no record for 'Table 2', but the table 1 and table 3 have records associated with them.

  Is it possible to hide the table 2 and get the following provision -

  Table 1

  Table 3

  According to the schema, table 2 should hide, and table 3 should get reordered under table 1 directly.

  Best regards

  Ankit Gupta

  Hello

  You can set the property visible from the table to something like #{bindings.. estimatedRowCount gt 0}

• Fill the programmatic view object during execution

  Hi all

  I have a requirement to switch between the three different data source during execution in a single page. The user interface and the field names are the same for these three cases, but data from various sources (queries).

  So, imagine that we have 3 objects in view which has implemented read-only (object request depending on the view) and we want to fill a display object at the main performance as a data source for my page.

  My idea is to use "Prgorammatic view object" for this data source and then fill dynamically the contents of one of the three objects view read-only based on a setting in the user's selection.

  First of all, I want to know if it is thin approach and if yes, then get some points on the implementation or any other sample.

  I found this example:

  http://techiecook.WordPress.com/2011/05/17/programmatically-populate-view-objects-in-Oracle-ADF/

  Thanks in advance,

  Nasser

  Hello

  It is more a case of use for Adaptive connections. See:https://blogs.oracle.com/groundside/entry/towards_ultra_reusability_for_adf

  You can use EL to change the name of the ViewObject that an iterator in ADF queries its data. If the switch is on the link layer and there is no need for programmatic view objects. Unlike in the article of the blog above, VO 3 exist in your case then you don't need to create on the fly. Just change the name of VO in the managed bean referenced

• Pass the value of the variable during execution

  Hello
  
  I have a package with a set of interfaces and three other variables.
  
  I want to pass the value of the variable at runtime, based on the value passed I want to decide which interface to run then. How can I do this? I got a set variable but I want to asssign the value during execution.
  
  Any help is greatly appreciated.
  
  
  Thank you
  San

  You have many options to achieve this goal.

  1. keep the run settings in the database, extract the Variables in a time of refreshment and use these variables in your Interfaces to get values of execution.

  2. change the value to the variables on the outside. You can declare a variable in a package as a step of the statement, and then use the variable in your interface in a successive step in your package. Then, create a scenario of your package and creating the scenario, it will prompt you to include the variables that you want to include as a startup parameter. Choose the one (s) concerned. Citing this scenario using Java or an OdiStartScen command or by using Webservices ODI externally, you can provide values of the runtime as a result.

  I hope this helps.

  Concerning
  A
