• How to bind the AM method to EL

  I want to connect the AM method in EL expression to control the user interface component attribute made,.

  {in my AM I create a method and expose this data control method, rendering for the UI component attribute is defined as that "rendered =" #{bindings.isRayTesting.result ""} ", it seems that this method cannot be performed until the page is rendered,

  How do I make the excute method before the page is rendered.

  the AM method

  for example:

  	public boolean isRayTesting() {}
  	Returns false;
  	}

  {in my AM I create a method and expose this data control method, rendering for the UI component attribute is defined as that "rendered =" #{bindings.isRayTesting.result ""} ", it seems that this method cannot be performed until the page is rendered,

  To call the method that is exposed in the pagedef using EL, you need something like: #{bindings.isRayTesting. {Run} so there is no way to implement your use case using only the EL.

  Also, many of the properties of the JSF component (as "lent") are evaluated several times in the life cycle JSF request so an expensive operation in them can significantly degrade performance.

• How to reproduce the traditional method in RMAN?

  How can I do the following by using RMAN?
  

  DB version 10.2.0.4
  RedHat 5.2
  I'm not using a rman catalog

  in the past I have moved large data bases of 1 server to another with downtime of 5 minutes using backups made the old way to put tablespaces into backup mode and to make copies of data files.
  
  I used the following method:
  = > Part 1
  STARTUP NOMOUNT
  CREATE CONTROLFILE REUSE DATABASE "VPMY" RESETLOGS ARCHIVELOG value
  MAXLOGFILES 32
  MAXLOGMEMBERS 3
  .. .etc
  LOGFILE
  ... save file names
  DATA FILE
  ... list data files
  US7ASCII CHARACTER SET;
  
  = > Part 2
  Until the downtime scheduled, I copy logs archiving from the production server to the new, and run the following command to apply the last archiving logs:
  RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL;
  -> AUTO < -.
  
  = > Part 3
  After you apply the last archive log all restrict mode.
  ALTER DATABASE OPEN resetlogs;
  
  
  My question is, how do I part 2 in RMAN. I managed to duplicate databases and restore databases with rman to another server, but this obviously covers only the data to the point of backup. How can I make the elements above 1-3 with downtime of about 5 minutes like I did using old methods?
  
  Any help is very appreciated.

  += ==> Part 2 +.
  Until the downtime scheduled, I copy logs archiving from the production server to the new, and run the following command to apply the last archiving logs:
  RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL;
  -> AUTO<>
  My question is, how do I part 2 in RMAN.

  When you run this game with rman, you just run rman > restore database if archivelogs placed (or transfer) another directory before running the recovery you need to catalogue start with "arch_location" through rman

  I managed to duplicate databases and restore databases with rman to another server, but this obviously covers only the data to the point of backup. How can I make the elements above 1-3 with downtime of about 5 minutes like I did using old methods?

  I don't think this limit. But in mode archivelog (in your case), you can take (hot) backup with rman even while the database is open. You can try as below

  rman target /
  configure controlfile autobackup on;
  backup database plus archivelog
  

  Then copy (transfer) these files to the new server, backup and

  export ORACLE_SID=
  rman target /
  startup nomount;
  restore spfile from 'autobackup_location';
  startup force nomount;
  restore controlfile from 'autobackup_location';
  alter database mount;
  catalog start with 'bakup_location';
  restore database;
  recover database;
  alter database open resetlogs;

• Connector WFD SDK - how to call the server method?

  I use the FMS connector C++ to perform editing work. And I am obliged to call a method side server.

  I tried to use the INetConnection::call () method, but it seems to be successful.

  
  The specification of the server FMS told me to do,

  1. call the server method,

  NC. Call (streamname, null, "FCPublish");

  
  2. implement a callback function onFCPublsih

  nc.onFCPublish = function (info) {...}

  How can I implement the latter with FMS Connector C++?

  The FMS connector document include a subject too little on the method call server-side.

  WFD SDK connector, the netconnection call prototype looks like this.

  virtual bool call (const char * funcName, const unsigned char * arguments, unsigned size, OnResultHandler * result) = 0;

  Thus, you will have to serialize the arguments and then pass it to call the function.

  Check

  bool FMSCTester::testCall (const char * cmd, const char * arg)

  method in FMSCTester sample application that comes with the software development kit how to serialize and call the function.

  For Server callbacks, you have to implement a netconnection sink with the onCommand method is called when the server calls a method on the client.

  The onCommand prototype looks like this,

  onCommand Sub (const char * cmd, const unsigned char * arguments, unsigned bufLen, IRetValue * retVal)

  again, you can check the MyNCSink class in the FMSCTester sample project for an implementation of onCommand.

  In my application I am stretching from Verticalmanager to my class and display data in tableview.

  but the problem is that all the data is displayed with the scroll bar. To get the scroll for the tableview bar

  I sends you only (code tableview) if someone meets me, I want to paste all of the code.

  Please answer

  Please stand to be corrected if I'm wrong, you want to set the height of a manager who is unscrollable, in a Manager, a list field must be added, which is scrollable. First make the screen unscrollable by great call (Manager.No_VERTICAL_SCROLL); Then create a handler, override its methods getPreferredWidth(), getPreferredHeight() and sublayout(), as below:

  mainManager = new VerticalFieldManager(Manager.VERTICAL_SCROLL){
              public int getPreferredWidth()
              {
                  return super.getPreferredWidth();
              }
              public int getPreferredHeight()
              {
                                  // fixed height
                  return height;
              }
              protected void sublayout( int maxWidth, int maxHeight )
              {
                  super.sublayout(getPreferredWidth(),getPreferredHeight());
                  setExtent(getPreferredWidth(),getPreferredHeight());
              }
          };
  

  mainmanager add to your list.

• Threads Java - how to prevent the calling methods between objects

  I have two objects i.e. ObjectClass1 and ObjectClass2 and two threads Thread1 and Thread2. I need Thread1 to run the methods A and B of 1 of the ObjectClass and keep him execution methods C and D on ObjectClass2 and at the same time (at the same instance), I need Thread2 to run C and D of ObjectClass2 methods and keep him execution of methods A and B on 1 ObjectClass without producing a blockage.

  Please see the order in which I get the locks
  Thread1: {obj1, obj2} and Thread2: {obj2 obj1} which is the case perfect deadlock.

  This is exactly the opposite of my suggestion, and I even stated explicitly that if you do this, you define yourself in deadlock.

  What I said:

  1. you avoid deadlock so that any thread that needs to acquire lock1 both QL2 always does in a consistent order, like first on lock1, then inside this block synchronization, sync on QL2. If a son not {lock1 {QL2}} and the other not {QL2 {lock1}}, that's how you get blocked.

  Sorry if I wasn't clear enough. All threads need to acquire locks in the same order:

  //  ----- What I suggested ---
  // T1
  sync (lock1) {
    sync (lock2) {
      // stuff
    }
  }
  
  // T2
  sync (lock1) {
    sync (lock2) {
      // stuff
    }
  }
  
  // ---- What I said not to do, but you did ---
  // T1
  sync (lock1) {
    sync (lock2) {
      // stuff
    }
  }
  
  // T2
  sync (lock2) {
    sync (lock1) {

• How to call the AM method that accepts the parameter other than a string

  Hello
  
  I need to pass 2 parameters from the date of my method of AM.
  I checked the jdev doc and found the method which can be used for anything other than a string below parameter
  
  public Serializable invokeMethod (String methodName,
  [Serializable] methodParams,.
  Class [] methodParamTypes)
  
  one thing that I am not able to understand how to pass multiple dates in a single parameter of the class.
  can anyone tell me the syntax to invoke method for the passage of 2 dates.

  Hello

  Suppose you have a string and two date parameters

  Test of the chain;
  Date date1;
  Date2 date;

  Then move it like this

  OAApplicationModule am = pageContext.getApplicationModule (webBean);

  Serializable [] parameters is {test, date1, date2};.
  Class [] paramTypes = {String.class, Date.class, Date.class};
  am.invokeMethod ("initSummary", parameters, paramTypes);

• How to replace the onMenu methods?

  Hi, I can simply call to some Menu key methods:

  The screen onClose() method is responsible for MenuItem 'Close' which is present by default in the menu of the screen... You can override to get the desired results!

  It seems to have moved or from Lightroom CC?

  Here's a screenshot of what I mean...

  

  If anyone can help, I'd appreciate it.

  PS I don't want use sync that's not exactly what I'm after that other people have suggested.

• LOV depending on the separate View object with ViewCriteria

  Hello

  I use JDev 12.1.3. My use case is the following - I've simplified as much as I can. I insert and update the SFGroupUser table, but I want the LOV to the UserID field be limited to only the users that are connected to today's society through the SFCompanyUser table. Here is the structure of the table:

  The key point is that when you assign users (SFUser) (SFGroup) groups in the SFGroupUser table, not all users may be assigned to a group because the groups are part of the business and the users are associated with one or more companies. Could not assign a user to a group that belongs to a company that the user is not assigned to. If GroupID 1 belongs to CompanyID 1 and 1 UserID is also assigned to number 1 in the SFCompanyUser table, then Pseudo1 can be assigned to GroupID 1.

  In my ADF application, I created the entity objects and visualization of objects for all tables and all associations and links. I configured the perspective in the AppModule have a master relationship / detail like this:

  

  In the SFGroupUserView I put in place a LOV to the UserID field. Is this LOV I want to limit just users who are assigned to the current society (the master of the relationship master / detail). It is possible to limit the LOV uses a separate view object, in this case a SFCompanyUser based, where society is today's society?

  I worked with a view read-only as the LOV object. This VO joins SFCompanyUser and SFUser and has a view with a parameter of binding criteria for the CompanyID information. It seems that it is the way to go, but I do not see how to assign the current CompanyID to the variable binding.

  Another point. I read different things, including corner Code article http://www.oracle.com/technetwork/developer-tools/adf/learnmore/44-restrict-lov-169186.pdf of Frank Nimphius. In this article, it updates a variable binding in a listener of the popup. I would like to have all the logic to stay in business if possible components. The idea is that the JSF page displays data controls in the form of a table of editable with a menu item drop-down selectOneChoice.

  Kind regards

  Steve

  I solved my problem. The precious documentation carried out since the development of the Fusion of Web Applications with document Oracle Application Development Framework in section 5.12, in particular section 5.12.2 - How to define cascading lists LOV-Enabled view object attributes: https://docs.oracle.com/middleware/1213/adf/develop/adf-bc-vo-queries.htm#ADFFD349.

  Using a view criteria named in the view LOV object was correct. When the attribute of username in the SfgroupuserView view object has been configured to use the LOV, a view accessor was created for the SfgroupuserView. The accessor view points to the LOV view object. Edition of the accessor of view I said to use the criteria of view named object View LOV. The problem was that the ID of the company in the main table (sfgroup) was not an attribute of the SfgroupuserView view object, so I was not able to assign a value to the variable binding. So, I added the entity sfgroup as one of the entities that the SfgroupuserView was based on and then added the companyID attribute. I then used the new attribute companyID as the value to be assigned to the variable binding, the criteria of display for the view LOV object in view accessor.

  

  Now, everything works well in the AppModule. When you insert a new record in SfgroupuserView1 the user's selection is a drop-down list that displays only users assigned to today's society.

• How to check the page dirty with default values existing in viewObject?

  Hi all

  I use JDeveloper 11.1.1.4.

  I have two pages in my application. I am browsing for page2 page1.

  Before opening page 2 I created new line page 2 notice of object using method 'Create Insert()' with some default values by using the ViewRowImpl class.

  My problem is that I have a button to return to Page 2. If I click the back button, then check the Application module is dirty or not.

  But it always shows AM is dirty due to I'm setting some default values in ViewRowImpl. If I avoid the default values in ViewRowImpl then AM dirty check works fine.

  My Question is how to check the AM (or) dirty Page with default values in the object view?

  My bean Codes:

  Links DCBindingContainer = (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();

  DataControl dc = bindings.findDataControl("AppModuleDataControl");

  ApplicationModuleImpl am = ((ApplicationModuleImpl) dc.getDataProvider ());

  If (am.getDBTransaction (.isDirty (()))

  {

  return "Page is dirty."

  }

  My Jspx Codes:

  < af:commandLink id = "cl6" text = '2 '.
  shortDesc = "Add Row in Page2"
  actionListener = "#{bindings." Action CreateInsert.execute}' = 'Edit' >

  Thank you

  David...

• How to read the value of an independent textInput element inside the method?

  Hello
  
  I had a group of detail based on a readonly viewobject. I added an independent element textInput, you say, EndDate to this group that the user can enter a value inside. Now, when I run the app I select a row in the table and press a button that triggers a method inside a bean. My question is how I read the value in independent textInput (EndDate) within the method element?
  
  getTable () .getRowData () does not print the unbound attribute. It seems that it only contains attributes underlying viewobject
  
  I use JDev 11.1.1.4
  
  Kind regards
  Will do

  Will do,

  You can better create a transitional attribute for that in your view object, so you can use a regular expression #{row.bindings...} to get the value.
