• Root & nested AM

  Dear all

  I have Root with nested application modules, that AM root can access your nested,

  My Question...

  I needed to draw up methods at the level of the AOS and this method use your nested, is there a difference when I do in impl of AM and Nested impl AM root?

  If so, which one is better?

  I use jdev ADF 12 c / BC - JSF projects

  Thank you

  There is no difference in the views of programmers. If you use am nested within the user interface of the data control manages the path. If you want to access a nested root am am you will need to either use findApplicationModule method out use the evaluator of the generation of framework for you.

• Cannot access module app root in a nested

  I use Jdeveloper 11 g R2 (11.1.2.3) & Weblogic 10.3.5.0
  
  I have a root application module and a few nested application nested under the root one in my ADF application modules
  I have a few common methods under the application module root Impl class and try to access in the nested Impl classes
  like this (this code is in the nestedAppModuleImpl class):
  
  Root RootAppModuleImpl = (RootAppModuleImpl) someViewObject.getDBTransaction () .getRootApplicationModule ();
  root.doSomething ();
  
  When I run the above code, this exception is thrown:
  
  oracle.jbo.server.ApplicationModuleImpl cannot be cast to mypackage. RootAppModuleImpl
  
  Any comment or workaround?
  What is the solution?
  
  Concerning
  Mohsen

  Mohsen, there is something terribly wrong with your code.

   //(This code is in nestedAppModuleImpl class):
  
  RootAppModuleImpl root = (RootAppModuleImpl)someViewObject.getDBTransaction().getRootApplicationModule();
  root.doSomething();
  

  is not supposed. DoSomething() returns really a RootAppModuleImpl? You can access the root of the module application embedded by request module

  RootAppModuleImpl root = (RootAppModuleImpl)getRootApplicationModule();
  

  If you get a class cast exception, this means that there is something wrong with your RooAppModuleImpl. Extend ApplicationModuleImpl? If so, the cast should be possible.
  Is root of the RootAppModuleImpl type request module? then only you can access common methods after obtaining the application root module.

  the following method

  private ViewObject getAccountExistsView(DBTransaction t) {
  ApplicationModule root = t.getRootApplicationModule();
  ViewObject vo = root.findViewObject("MemberExistsView");
  if (vo == null) {
  vo = root.createViewObject("MemberExistsView","model.MemberExistsView");
  }
  return vo;
  }
  

  not make sense to me. Where is this method? in the RootAppModuleImpl? If so, why do you call getRootApplicationModule? You are in the application root Module. I can "commentary on the createViewObject, you call, but my feeling is that you don't need either. The view that you create must exist already if your application module are configured correctly.

  And you are right, you should not call createRootApplicationModule if it is not needed. In your case, what it is not!

• A few questions on the framework of the actor

  Hi all

  I tried to get my head under the actor and begins to see the light at the end of this tunnel-no need of sunglasses right away, because I have a few questions remaining:

  1. data transfer :

  So far I've had a quick glance the evaporative cooler model and actor model, as well as worked through the LabVIEW actor Framework Basics by labvolution. These examples are pretty clear for me now. What I don't understand though, is how you are supposed to provide "real" data These examples use only references and then update using the "value" property This may not be very fast, but is probably still enough for user interface applications. But what happens if I have a player who generates data by reading example of a card and I have, let's say, want to detach this far from the data backup process in a file. How I would pass large amounts of data between stakeholders effectively.

  2. using the framework of the actor with RT:

  In presentations to the AF, I saw that they always mentioned that it was completely "capable RT. While this may well be true for the RT itself system, yet once I wonder how to transfer data from an actor of the RT of a player in Windows. Yet once again, suppose I want to generate data on a cRIO and save that data on the host PC. I will establish a channel of communication between the target myself by network flow or similar? It defies any sort of encapsulation of the AF in my opinion...

  3. set the actors:

  However, what worries me the most, is the definition of the actors. How can you know what is a player in your system? Each card set as an actor? Define you each device as an actor and consolidate all I/o to the breast? Is there an easy way to know how to set the actors?

  4. technical support:

  While working with the examples, I found that the debugging can be quite difficult. I had several cases of "Not executable Subvi" this point through several other live who finally call something dyynamically and from there, you discover that one of your screw is broken. Is there an easy to know what is the problem? I know there are modules for LabVIEW that are designed to turn on debugging part of the actor, but who would not be available in a review of the CLA, where you will have only a base installation of LabVIEW.

  5 root and nested actors:

  Finally, I wonder what root and nested average actor. So far my understanding is that the actor root is the parent actor you cast in the launch of VI and nested the actors are all children who serve the actor parent and are, most of the time, launched since the actor-actor of parent nucleus. Is this correct? Is there a better definition of it?

  Any help on this is greatly appreciated. I'm looking forward to the discussion and interested if you frequently use the framework of the actor or if you have abandoned it even once after using it.

  See you soon,.

• file name is contained in several sites. Please open the site...

  Why Dreamweaver has a problem with that? Yes, the file name is used in several sites, but that particular file is unique to another Site Local folder and has a meaning local testing server. Everything that Dreamweaver is fully aware. Why, when Dreamweaver gets to do these amazing stuff, I have to click the appropriate Site?

  Bob

  Sorry, I don't have an answer to that. Even when I have several open sites pages, I've never been invited to switch to another site when registering.

  On the other hand, I do not have any installation where I use common files that require changes in Dreamweaver. One of the flaws of Dreamweaver is that it does not offer a simple way to work with files that are stored outside of the root of the site. Its origins date back to the time of static HTML sites (actually, I think that's what most people probably still use it to), so everything is based on all of the files within the root of the server.

  A technique that some people use to work with files outside of the root of the site is to create a site for external files and then nest to public folders inside. Dreamweaver warns against this, but it doesn't prevent you to do so. However, I think that several sites within a common root of nesting can lead to the kind of problem that you are experiencing.

• Nesting of the ADFLibs App Modules - jdev 11.1.2.3

  
  Hello:

  I have a dashboard with 6 tabs application. On each tab is a stubborn an ADFLib workflow. Note: each BTF has its own App Module.

  In the application of Captain dashboard, the BTF ADFLibs are deleted as regions in each tab. The master App has its own module of the application and I want to nest each module App BTF under the App Module only at the master app.  The reason is that each tab of the application currently creates a separate connection to the DB. I want the Master application only to create a DB connection for the entire application.

  In the range of resources, I can see the App Modules of the separate ADFLibs and I added these Modules App on the Master project, but AM newly added does not appear under the master App Module for me nest. (in the App Module-> - model data-> Instances of application Module)

  How can I nest several ADFLibs AM under only one App Module of Master?  (the ADFLibs AM displayed not in the Instances of app Module in the Master App)

  Thank you

  This blog shows how to do the nesting in the model layer: http://dayasahu.blogspot.jp/2013/07/adf-bc-import-feature.html?utm_source=dlvr.it&utm_medium=twitter

• Application module is not a root app module, but has no parent

  Hello
  
  I use JDeveloper 11.1.2.1.0
  
  I created a pl/sql procedure and he ran in the SQL worksheet, the procedure worked very well.
  After that, I created a method in request Module to access the procedure of the h. The client interface of the method was created and accessed the procedure and the procedure has worked well.
  After I created a View object and attached to the AM and let fall the attributes of the VO as a form on the page and tried to access the method in a bean to support am, there had to be two parameters passed to the procedure, that's why I took the AM method with a bean of support.
  
  But inside the AOS, there is a following line of code:

  stmt = getDBTransaction().createCallableStatement(str.toString(), 1);

  On this line, an error is being run, like this:
  
  < font color = "red" > oracle.jbo.InvalidOwnerException: Houston-25301: Application ApplicationModuleImpl_6 module is not a root app module, but has no parent < / make >
  
  Why does this error happen?
  
  Thank you
  Nigel.

  DemoImpl demo = new DemoImpl();
  

  You can't do that. Sascha has suggested, the problem being that you try to create an instance of AM in the wrong way.

  The best way to do this:

  (1) make sure "prop" is exposed on the client interface
  (2) add a link to your definition of prop page. Bind the parameter values as the case

• How to get the view of entity impl and get app module

  I want to know how to access the entity Imp Appmodule as I want to call the entity Impl Module application method.
  And I want to how to call view also entity impl object to get the value of the view attribute object.
  I want to get view object and entity Impl App Module to use in validation

  If you need validate, write this method in the implementation class entity itself. There is no point in writing this method in the app module and call this method from the entity, it's a bad habit. If you want to get some values of a VO, define view accessor in the EO. Through the accessor, you can see the required values.

• Nested vs Application Module Module Application root

  I have a popup that is used to create a new address / location container city, State, address line 1, line 2 address etc. I want to create this reusable component. I created an app for this Module with the name "LocationService".
  I created all of the links on this page. Now, I want to use this in the context of other use cases that have their own services. Should I now nest LocationService inside each service where I can use it, or there is another way to do this.

  If I want to commit to the time when I save stuff together. Then, what is the best way to keep the possibility of re-use and other things.

  In this case, the popup taskflow requires existing transaction value
  On the appellant/flow page, simply use the AM root rather than nested...

  Is - the current running in the server or Jdeveloper?

  If it is the server, you did all the changes recently? Did transfer a file? If so, you correctly transfer in binary mode?

  Delete the class files, copy the files again (binary mode if you transfer files class if the java files, transfer in ascii mode and then compile it in the server).

  Bounce the server and see what happens.

  Let us know how it goes.

  See you soon

• Link Module and DB App

  I use 11.1.1.6 JDeveloper.

  I have 20 modules app in my application. Each is set up using the weblogic Server Data Source.

  On Weblogic, I configured the Data Source, pooling of max size 50.

  While I tried to load test the application, I found the connection DB grow quickly with users to connect and eat 50 connections with only 10 user sessions.

  I had

  weblogic.jdbc.extensions.PoolLimitSQLException: weblogic.common.resourcepool.ResourceLimitException: no resources currently available in the pool

  CentralConnection to allocate to the applications, please increase the size of the pool and try again...

  at weblogic.jdbc.common.internal.JDBCUtil.wrapAndThrowResourceException(JDBCUtil.java:252)

  
  

  Is it assumed that all modules to share the DB connection? seems each module contains a DB data source and never release.
  

  
  

  What configuration I missed?

  
  

  Thank you

  You can create of 01:00 and adds the other AMs as nested AMs (but this will also require changes in pageDef files)

  What is the configuration that is optimized for the following scenarios:

  1. 100 concurrent users

  2. top of 1000 concurrent users

  Depends on the definition of 'simultaneous user '. If users are concurrent on db level, then you must have db, WLS datasource and AM pool configured to support connections simultaneous db at the minimum of 100 (or 1000).

  Is they are simultaneous only on the level of the web session (so they access db at the same time), then it can be treated with the smaller number of cases of AM and db connections (but with AM activation/passivation, which can affect performance).

  Here are some tips:

• One or more modules of App?

  Hello! Can someone explain to me when it is necessary to create several App modules in the project template? And when it is beter to all BC in a single App Module?
  
  I have a lot of BC in my application and I want to add in several modules App.
  
  Waiting for answers, cordially, Debuger!

  Debugger,
  You can only nest AMs if either you use the methods of the AM or you need to commit both together, otherwise, they can be independent.
  Simple logic to make AMs other than advice and standards referred to in the documentation provided by Jabr & Umesh is
  -keep similar functionality to 01:00 (let's say you have a rent an employee flow & pay another stream, you can have separate AMs for them if they donot use of similar artifacts)
  -Try to keep all these artifacts that need to be committed at once, based on the flow of your UI at 01:00.

• Modules of the app and objects of entity-caching issue

  Hello
  
  I'm working on an application that allows users to distribute scholarship funds to students. My main page uses a table based on a view object App Module has to display the information of the student. The attributes of this VO are based on an entity object, let's call it "foo." This page has a dynamic region popup to allow to define details of the scholarship... the called pre-existing taskflow creates new lines in the objects view App Module b, whose attributes are also mapped to EO foo or mapped to an EO with associations with the foo.
  
  So, with the new lines created, I quit my dynamic region, re - run my application Module has VO, and... no line. It is my understanding that, even if the your were in different Modules App, the fact they were using attributes based on the same EO would allow the lines created to persist in a cache of the entity. Within taskflow the dynamics of the region, there is another outcome where lines are displayed in VO that exists in the App Module b... so I'm pretty confident that my lines are created...
  
  Is there some steps needed to pass data between modules app? Is it impossible? I lose the EO cache when switching between taskflows? Or something else could be the problem?
  
  Thank you!

  Unfortunately your understanding "that the your were in different Modules of the application, the fact that they used the same EO-based attributes would allow the lines created to persist in a cache of the entity '... is incorrect.

  As you are 'reuse' OS through the AMs, the OS cache is instantiated two times, one for each AM, because AMS have entirely separate transactions (to the AMs of the nested exception... but you don't mention you have nested for your AMs so I figure that's irrelevant for you). This is the point of the AMs, separate transactions, so the behavior you're seeing. If you made your sub 2 the same AM, you would be able to reuse the cache of 'foo' EO. Nesting potentially your AMs under a parent AM would have the same effect.

  Note, it becomes a little more complicated in a workflow scenario, because workflows can instantiate separate transactions on a single AM optionally.

• Must install Labview App on cFP2200 with feature plug &amp; play for measurement modules

  Hello

  I am trying to install a monitoring software on cFP2200 devices. This software uses anywhere from 1 to 8 modules of I-102. I want to be able to deploy my build to the fieldpoint without having to know in advance how many modules will be there.

  My plan to achieve this was to design my application to assume that all modules HAVE 102 were available to read to go, throw an error that I catch and delete if they weren't. It works perfectly in tests of interpreted code. I managed to disconnect the field point, 102 HAVE devices to different locations than before, and my software could find them and ignore the slots where were connected HAVE 102 s.

  A question is asked now when I try to deploy a compiled version of this app on the fieldpoint. When I do that, I get a "conflict resolution" popup that lists all of the I-102 s who are not connected at deployment time. I have to choose 'cancel the deployment' or 'Skip deployment' in these cases. So I am unable to find I-102 modules if I move them to one location other than when they were connected to install or put new ones in.

  We will put these modules at customer sites and we want the ability to develop so that it contains some 102 HAVE more or less as the customer systems expand and contract. Under the current situation, I have to re - install the software manually whenever they move a module that is not really an acceptable long term solution.

  Are there ideas about how to address the issue?

  Thank you

  Kelsey Golden

  I just realized that the "conflict resolution" window really means nothing. As long as I select 'Skip', I can always move the modules or new install! It makes me wonder what the conflict resolution is intended in the first place if he is not actually stop me using the modules later.

  For all those who want plug-and-play in the future, my solution essentially try to read all possible addresses and ignore those throwing errors basically seems to be the way to do this. Just ignore the stupid conflict resolution window. I of course hope that the fact that I can still install modules in locations where conflicts implicitly he wasn't their installation is not a defect that NEITHER patch later outside.
