    BPM Process Accelerator Packs – Update | Pat Shepherd Architect Pat Shepherd shares several resources relevant to the new Oracle Process Accelerators for Oracle Business Process Management. Oracle BI EE Management Pack Now Available for Oracle Enterprise Manager 12cR2 | Mark Rittman A handy and informative overview from Oracle ACE Director Mark Rittman. WebSockets on WebLogic Server | Steve Button "As there's no standard WebSocket Java API at this point, we've chosen to model the API on the Grizzly WebSocket API with some minor changes where necessary," says James "Buttso" Buttons. "Once the results of JSR-356 (Java API for WebSocket) becomes public, we'll look to implement and support that." Oracle Reference Architecture: Software Engineering This document from the IT Strategies from Oracle library focuses on integrated asset management and the need for efffective asset metadata management to insure that assets are properly tracked and reused in a manner that provides a holistic functional view of the enterprise. The tipping point for cloud management is nigh | Cloud Computing - InfoWorld "Businesses typically don't think too much about managing IT resources until they become too numerous and cumbersome to deal with on an ad hoc basis—a point many companies will soon hit in their adoption of cloud computing." — David Linthicum DevOps Basics: Track Down High CPU Thread with ps, top and the new JDK7 jcmd Tool | Frank Munz "The approach is very generic and works for WebLogic, Glassfish or any other Java application," say Frank Munz. "UNIX commands in the example are run on CentOS, so they will work without changes for Oracle Enterprise Linux or RedHat. Creating the thread dump at the end of the video is done with the jcmd tool from JDK7." Frank has captured the process in the posted video. OIM 11g R2 UI customization | Daniel Gralewski "OIM user interface customizations are easier now, and they survive patch applications--there is no need to reapply them after patching," says Fusion Middleware A-Team member Daniel Gralewski. "Adding new artifacts, new skins, and plugging code directly into the user interface components became an easier task." Daniel shows just how easy in this post. Thought for the Day "I have yet to see any problem, however complicated, which, when looked at in the right way, did not become still more complicated." — Poul Anderson (November 25, 1926 – July 31, 2001) Source: SoftwareQuotes.com

  • Connecting SceneBuilder edited FXML to Java code

    - by daniel
    Recently I had to answer several questions regarding how to connect an UI built with the JavaFX SceneBuilder 1.0 Developer Preview to Java Code. So I figured out that a short overview might be helpful. But first, let me state the obvious. What is FXML? To make it short, FXML is an XML based declaration format for JavaFX. JavaFX provides an FXML loader which will parse FXML files and from that construct a graph of Java object. It may sound complex when stated like that but it is actually quite simple. Here is an example of FXML file, which instantiate a StackPane and puts a Button inside it: -- <?xml version="1.0" encoding="UTF-8"?> <?import java.lang.*?> <?import java.util.*?> <?import javafx.scene.control.*?> <?import javafx.scene.layout.*?> <?import javafx.scene.paint.*?> <StackPane prefHeight="150.0" prefWidth="200.0" xmlns:fx="http://javafx.com/fxml"> <children> <Button mnemonicParsing="false" text="Button" /> </children> </StackPane> ... and here is the code I would have had to write if I had chosen to do the same thing programatically: import javafx.scene.control.*; import javafx.scene.layout.*; ... final Button button = new Button("Button"); button.setMnemonicParsing(false); final StackPane stackPane = new StackPane(); stackPane.setPrefWidth(200.0); stackPane.setPrefHeight(150.0); stacPane.getChildren().add(button); As you can see - FXML is rather simple to understand - as it is quite close to the JavaFX API. So OK FXML is simple, but why would I use it?Well, there are several answers to that - but my own favorite is: because you can make it with SceneBuilder. What is SceneBuilder? In short SceneBuilder is a layout tool that will let you graphically build JavaFX user interfaces by dragging and dropping JavaFX components from a library, and save it as an FXML file. SceneBuilder can also be used to load and modify JavaFX scenegraphs declared in FXML. Here is how I made the small FXML file above: Start the JavaFX SceneBuilder 1.0 Developer Preview In the Library on the left hand side, click on 'StackPane' and drag it on the content view (the white rectangle) In the Library, select a Button and drag it onto the StackPane on the content view. In the Hierarchy Panel on the left hand side - select the StackPane component, then invoke 'Edit > Trim To Selected' from the menubar That's it - you can now save, and you will obtain the small FXML file shown above. Of course this is only a trivial sample, made for the sake of the example - and SceneBuilder will let you create much more complex UIs. So, I have now an FXML file. But what do I do with it? How do I include it in my program? How do I write my main class? Loading an FXML file with JavaFX Well, that's the easy part - because the piece of code you need to write never changes. You can download and look at the SceneBuilder samples if you need to get convinced, but here is the short version: Create a Java class (let's call it 'Main.java') which extends javafx.application.Application In the same directory copy/save the FXML file you just created using SceneBuilder. Let's name it "simple.fxml" Now here is the Java code for the Main class, which simply loads the FXML file and puts it as root in a stage's scene. /* * Copyright (c) 2012, Oracle and/or its affiliates. All rights reserved. */ package simple; import java.util.logging.Level; import java.util.logging.Logger; import javafx.application.Application; import javafx.fxml.FXMLLoader; import javafx.scene.Scene; import javafx.scene.layout.StackPane; import javafx.stage.Stage; public class Main extends Application { /** * @param args the command line arguments */ public static void main(String[] args) { Application.launch(Main.class, (java.lang.String[])null); } @Override public void start(Stage primaryStage) { try { StackPane page = (StackPane) FXMLLoader.load(Main.class.getResource("simple.fxml")); Scene scene = new Scene(page); primaryStage.setScene(scene); primaryStage.setTitle("FXML is Simple"); primaryStage.show(); } catch (Exception ex) { Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex); } } } Great! Now I only have to use my favorite IDE to compile the class and run it. But... wait... what does it do? Well nothing. It just displays a button in the middle of a window. There's no logic attached to it. So how do we do that? How can I connect this button to my application logic? Here is how: Connection to code First let's define our application logic. Since this post is only intended to give a very brief overview - let's keep things simple. Let's say that the only thing I want to do is print a message on System.out when the user clicks on my button. To do that, I'll need to register an action handler with my button. And to do that, I'll need to somehow get a handle on my button. I'll need some kind of controller logic that will get my button and add my action handler to it. So how do I get a handle to my button and pass it to my controller? Once again - this is easy: I just need to write a controller class for my FXML. With each FXML file, it is possible to associate a controller class defined for that FXML. That controller class will make the link between the UI (the objects defined in the FXML) and the application logic. To each object defined in FXML we can associate an fx:id. The value of the id must be unique within the scope of the FXML, and is the name of an instance variable inside the controller class, in which the object will be injected. Since I want to have access to my button, I will need to add an fx:id to my button in FXML, and declare an @FXML variable in my controller class with the same name. In other words - I will need to add fx:id="myButton" to my button in FXML: -- <Button fx:id="myButton" mnemonicParsing="false" text="Button" /> and declare @FXML private Button myButton in my controller class @FXML private Button myButton; // value will be injected by the FXMLLoader Let's see how to do this. Add an fx:id to the Button object Load "simple.fxml" in SceneBuilder - if not already done In the hierarchy panel (bottom left), or directly on the content view, select the Button object. Open the Properties sections of the inspector (right panel) for the button object At the top of the section, you will see a text field labelled fx:id. Enter myButton in that field and validate. Associate a controller class with the FXML file Still in SceneBuilder, select the top root object (in our case, that's the StackPane), and open the Code section of the inspector (right hand side) At the top of the section you should see a text field labelled Controller Class. In the field, type simple.SimpleController. This is the name of the class we're going to create manually. If you save at this point, the FXML will look like this: -- <?xml version="1.0" encoding="UTF-8"?> <?import java.lang.*?> <?import java.util.*?> <?import javafx.scene.control.*?> <?import javafx.scene.layout.*?> <?import javafx.scene.paint.*?> <StackPane prefHeight="150.0" prefWidth="200.0" xmlns:fx="http://javafx.com/fxml" fx:controller="simple.SimpleController"> <children> <Button fx:id="myButton" mnemonicParsing="false" text="Button" /> </children> </StackPane> As you can see, the name of the controller class has been added to the root object: fx:controller="simple.SimpleController" Coding the controller class In your favorite IDE, create an empty SimpleController.java class. Now what does a controller class looks like? What should we put inside? Well - SceneBuilder will help you there: it will show you an example of controller skeleton tailored for your FXML. In the menu bar, invoke View > Show Sample Controller Skeleton. A popup appears, displaying a suggestion for the controller skeleton: copy the code displayed there, and paste it into your SimpleController.java: /** * Sample Skeleton for "simple.fxml" Controller Class * Use copy/paste to copy paste this code into your favorite IDE **/ package simple; import java.net.URL; import java.util.ResourceBundle; import javafx.fxml.FXML; import javafx.fxml.Initializable; import javafx.scene.control.Button; public class SimpleController implements Initializable { @FXML // fx:id="myButton" private Button myButton; // Value injected by FXMLLoader @Override // This method is called by the FXMLLoader when initialization is complete public void initialize(URL fxmlFileLocation, ResourceBundle resources) { assert myButton != null : "fx:id=\"myButton\" was not injected: check your FXML file 'simple.fxml'."; // initialize your logic here: all @FXML variables will have been injected } } Note that the code displayed by SceneBuilder is there only for educational purpose: SceneBuilder does not create and does not modify Java files. This is simply a hint of what you can use, given the fx:id present in your FXML file. You are free to copy all or part of the displayed code and paste it into your own Java class. Now at this point, there only remains to add our logic to the controller class. Quite easy: in the initialize method, I will register an action handler with my button: () { @Override public void handle(ActionEvent event) { System.out.println("That was easy, wasn't it?"); } }); ... -- ... // initialize your logic here: all @FXML variables will have been injected myButton.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent event) { System.out.println("That was easy, wasn't it?"); } }); ... That's it - if you now compile everything in your IDE, and run your application, clicking on the button should print a message on the console! Summary What happens is that in Main.java, the FXMLLoader will load simple.fxml from the jar/classpath, as specified by 'FXMLLoader.load(Main.class.getResource("simple.fxml"))'. When loading simple.fxml, the loader will find the name of the controller class, as specified by 'fx:controller="simple.SimpleController"' in the FXML. Upon finding the name of the controller class, the loader will create an instance of that class, in which it will try to inject all the objects that have an fx:id in the FXML. Thus, after having created '<Button fx:id="myButton" ... />', the FXMLLoader will inject the button instance into the '@FXML private Button myButton;' instance variable found on the controller instance. This is because The instance variable has an @FXML annotation, The name of the variable exactly matches the value of the fx:id Finally, when the whole FXML has been loaded, the FXMLLoader will call the controller's initialize method, and our code that registers an action handler with the button will be executed. For a complete example, take a look at the HelloWorld SceneBuilder sample. Also make sure to follow the SceneBuilder Get Started guide, which will guide you through a much more complete example. Of course, there are more elegant ways to set up an Event Handler using FXML and SceneBuilder. There are also many different ways to work with the FXMLLoader. But since it's starting to be very late here, I think it will have to wait for another post. I hope you have enjoyed the tour! --daniel

  • I flashed my DS4700 with a 7 series firmware, now my DS4300 cannot read the disks I moved to that lo

    - by Daniel Hoeving
    In preparation for adding a number of 1Tb SATA disks to our DS4700 I flashed the controller firmware from a 6 series (which only supports up to 2Tb logical drives) to a 7 series (which supports larger than 2Tb logical drives). Attached to this DS4700 was a EXP710 expansion drawer that we had planned to migrate out to our co-location to allieviate the storage issues we were having there. Unfortunately these two projects were planned in isolation to one another so I was at the time unaware of the issue that this would cause. Prior to migrating the drawer I was reading the "IBM TotalStorage DS4000 EXP700 and EXP710 Storage Expansion EnclosuresInstallation, User’s, and Maintenance Guide" and discovered this: Controller firmware 6.xx or earlier has a different metadata (DACstore) data structure than controller firmware 7.xx.xx.xx. Metadata consists of the array and logical drive configuration data. These two metadata data structures are not interchangeable. When powered up and in Optimal state, the storage subsystem with controller firmware level 7.xx.xx.xx can convert the metadata from the drives configured in storage subsystems with controller firmware level 6.xx or earlier to controller firmware level 7.xx.xx.xx metadata data structure. However, the storage subsystem with controller firmware level 6.xx or earlier cannot read the metadata from the drives configured in storage subsystems with controller firmware level 7.xx.xx.xx or later. I had assumed that if I deleted the logical drives and array information on the EXP710 prior to migrating it to the DS4300 (6.60.22 firmware) this would satisfy the above, unfortunately I was wrong. So my question is a) Is it possible to restore the DAC information to its factory settings, b) What tool(s) would I use to accomplish this, or c) is this a lost cause? Daniel.

  • Synchronizing files between Linux servers, through FTP

    - by Daniel Magliola
    I have the following configuration of servers: 1 central linux server, a VPS 8 satellite linux servers, "crappy shared hostings" I have a bunch of files that I need to have in all servers. Right now i'm copying them everywhere manually, but I want to be able to copy them to the central server, and then have a scheduled process that runs every now and then and synchronizes them (only outwardly, no need to try to find "new" files in the satellite servers). There are a couple of catches though: I can't have any custom software in the satellite servers, or do strange command line things that'll auto connect to them and send the files directly. I know this is the way these kinds of things are normally done, but the satellite servers are crappy shared hosting ones where I have absolutely no control over anything. I need to send the files over FTP I also need to have, in my central server, a list of the files that are available in each of the satellite servers, to make sure they are ready before I send traffic to them. If I were to do this manually, the steps would be: get the list of files in a satellite server compare to my own, and send the files that are missing get the list of files again, and store it in my central database. I'd like to know what tools are out there that can alleviate as much of this as possible, first the syncing, and then the "getting the list of files available in the other server". I'm going to be doing everything from PHP, not sure if there are good tools to "use FTP from PHP", which i'm pretty sure i'll have to do for step 3 at least. Thanks in advance for any ideas! Daniel

  • Error importing large MySQL dump file which includes binary BLOBs in Windows

    - by Daniel Magliola
    I'm trying to import a MySQL dump file, which I got from my hosting company, into my Windows dev machine, and i'm running into problems. I'm importing this from the command line, and i'm getting a very weird error: ERROR 2005 (HY000) at line 3118: Unknown MySQL server host '+?*á±dÆ-N+Æ·h^ye"p-i+ Z+-$?P+Y.8+|?+l8/l¦¦î7æ¦X¦XE.ºG[ ;-ï?éµ?º+¦¦].?+f9d릦'+ÿG?-0à¡úè?-?ù??¥'+NÑ' (11004) I'm attaching the screenshot because i'm assuming the binary data will get lost... I'm not exactly sure what the problem is, but two potential issues are the size of the file (2 Gb) which is not insanely large, but it's not trivially small either, and the other is the fact that many of these tables have JPG images in them (which is why the file is 2Gb large, for the most part). Also, the dump was taken in a Linux machine and I'm importing this into Windows, not sure if that could add to the problems (I understand it shouldn't) Now, that binary garbage is why I think the images in the file might be a problem, but i've been able to import similar dumps from the same hosting company in the past, so i'm not sure what might be the issue. Also, trying to look into this file (and line 3118 in particular) is kind of impossible given its size (i'm not really handy with Linux command line tools like grep, sed, etc). The file might be corrupted, but i'm not exactly sure how to check it. What I downloaded was a .gz file, which I "tested" with WinRar and it says it looks OK (i'm assuming gz has some kind of CRC). If you can think of a better way to test it, I'd love to try that. Any ideas what could be going on / how to get past this error? I'm not very attached to the data in particular, since I just want this as a copy for dev, so if I have to lose a few records, i'm fine with that, as long as the schema remains perfectly sound. Thanks! Daniel

  • Win2008: Boot from mirrored dynamic disk fails!

    - by Daniel Marschall
    Hello. I am using Windows Server 2008 R2 Datacenter and I got two 1.5TB S-ATA2 hard disks installed and I want to make a soft raid. (I do know the disadvantages of softraid vs. hardraid) I have following partitions on Disk 0: (1) Microsoft Reserved 100 MB (dynamic), created during setup (2) System Partition 100 GB (dynamic) (3) Data partition, 1.2TB (dynamic) I already mirrored these contents to Disk 1. Its contents are: (1) System partition mirror, 100 GB (dynamic) (2) Data partition, 1.2 TB mirror (dynamic) (3) Unusued 100 MB (dynamic) -- is from "MSR" of Disk 0, created during setup. Since data and system partition are mirrored, I expect that my system works if disk 0 would fail. But it doesn't. If I force booting on disk 0: Works (I get the 2 bootloader screen) If I force booting on disk 1 (F8 for BBS), nothing happens. I got a blank black screen with the blinking caret. I already made disk1/partition1 active with diskpart, but it still does not boot from this drive. Please help. Both partitions are in "MBR" partition style. They look equal, except the missing "MSR" partition at the partition beginning (which seems to be not relevant to booting). Regards Daniel Marschall

  • android memory management outside heap

    - by Daniel Benedykt
    Hi I am working on an application for android and we since we have lots of graphics, we use a lot of memory. I monitor the memory heap size and its about 3-4 Mb , and peeks of 5Mb when I do something that requires more memory (and then goes back to 3). This is not a big deal, but some other stuff is handled outside the heap memory, like loading of drawables. For example if I run the ddms tool outside eclipse, and go to sysinfo, I see that my app is taking 20Mb on the Droid and 12 on the G1, but heap size are the same in both, because data is the same but images are different. So the questions are: How do I know what is taking the memory outside the heap memory? What other stuff takes memory outside the heap memory? Complex layouts (big tree) ? Animations? Thanks Daniel

  • Delphi: Get MAC of Router

  • CakePHP: 2-level JOIN with one Query

    - by Daniel Magliola
    I have the following models in CakePHP: A Deposit belongs to an Account An Account belongs to a Customer I want to have a list of Deposits, and I need to show the name of the customer (so I have to join through the Customer). I also need to paginate this list. If I set Deposit->recursive = 2, I can get the Customer, however, CakePHP runs one query joining Deposit and Account, and then runs one query per each Deposit, to get the Customer. How can I make it get both models with only one query? I tried this, but it didn't work: $this->paginate = array('joins' => array( array( 'table' => 'customers', 'alias' => 'AccountCustomer', 'type' => 'inner', 'foreignKey' => false, 'conditions' => array('Account.customer_id = AccountCustomer.id') ) )); Any ideas?

    Hello everyone. I'm trying to make a self hosted WCF app that uses nettcpbinding but works in an environment without a domain. It's just two regular windows pc's, one is the server and the other one will be the client. The problem with this is that when I try to get the client to connect it's rejected because of the security settings. Can you please point me in the right direction as to how I can get this scenario to work? Should I (if possible) disable security? Is there another (hopefully simple) way to accomplish this?

  • Surgical slave reads for Ruby on Rails, mulitple databases.

    - by Daniel
    Greetings, I'm currently working on a multiple database rails application. I want to off load the SELECT queries on to the slave databases for only SOME of the databases or specific models. The issue is that in places, we swap out the current database connection and put in a different one for a short time; to load fixtures or to handle sharding. Does anyone have any recommendations on a ruby gem that 1. will split select/(sql writes) with a considerable amount of control. We want to handle just some models and we are looking for a neat surgical fix. 2. does not monkey around with activerecord. 3. is still being maintained. TIA -daniel

    Hi, I was writing some php code after a long sint doing ruby and I accidently wrote this: [root@ip-10-160-47-98 test]# cat run.php <?php class MyTest { public function run() { var_dump(this.test); } } $object = new MyTest(); $object->run(); [root@ip-10-160-47-98 test]# php run.php string(8) "thistest" [root@ip-10-160-47-98 test]# Now, this.test should have been $this-test, but the compiler was actually happy to let this run. Does anyone know how (this.test) got converted into a string "thistest"? Compiled and run on php 5.3.2 amazon instance ami-e32273a6 (CentOS 5.4) -daniel

  • Can I get a dump of all my databases *except one* using mysqldump?

    - by Daniel Magliola
    I'm currently using mySQLdump to backup my dev machine and servers. There is one project I just started, however, that has a HUUUUUGE database that I don't really need backed up, and i'll be a big problem to add it to the rest of the backup cycle. I'm currently doing this: "c:\Program Files\mysql\MySQL Server 5.1\bin\mysqldump" -u root -pxxxxxx --all-databases g:\backups\MySQL\mysqlbackup.sql Is it possible to somehow specify "except this database(s)"? I wouldn't like to have to specify the list of DBs manually, since that would mean that I'd have to remember updating my backup batch file every time I create a new DB, and I know that's not gonna happen. EDIT: As you probably guessed from my command line above, i'm doing this on Windows, so I can't do any kind of fancy bash stuff, only wimpy .bat things. Alternatively, if you have other ideas to solve this same issue, they are more than welcome, of course! Thanks Daniel

  • From interpeted to native code: "dynamic" languages compiler support

    - by Daniel
    First, I am aware that dynamic languages is a term used mainly by a vendor; I am using it just to have a container word to include languages like Perl (a favorite of mine), Python, Tcl, Ruby, PHP and so on. They are interpreted but I am interested here to refer to languages featuring strong capability to support the programmer efficiency and the support for typical constructs of modern interpreted languages My question is: there are dynamic languages can be compiled efficiently in native executable code - typically for Windows platforms? Which ones? Maybe using some third part ad-hoc tools? I am not talking about huge executables carrying with them a full interpreter or some similar tricks nor some smart module able to include its own dependances or some required modules, but a honest, straight, standard, solid executable code. If not, there is some technical reason inhibiting the availability of such a best-of-both-world feature? Thanks! Daniel
