ArchBeat Link-o-Rama Top 10 for December 9-15, 2012

- by Bob Rhubart

You click, we listen. The following list reflects the Top 10 most popular items posted on the OTN ArchBeat Facefbook page for the week of December 9-15, 2012. DevOps Basics II: What is Listening on Open Ports and Files – WebLogic Essentials | Dr. Frank Munz "Can you easily find out which WebLogic servers are listening to which port numbers and addresses?" asks Dr. Frank Munz. The good doctor has an answer—and a tech tip. Using OBIEE against Transactional Schemas Part 4: Complex Dimensions | Stewart Bryson "Another important entity for reporting in the Customer Tracking application is the Contact entity," says Stewart Bryson. "At first glance, it might seem that we should simply build another dimension called Dim – Contact, and use analyses to combine our Customer and Contact dimensions along with our Activity fact table to analyze Customer and Contact behavior." SOA 11g Technology Adapters – ECID Propagation | Greg Mally "Many SOA Suite 11g deployments include the use of the technology adapters for various activities including integration with FTP, database, and files to name a few," says Oracle Fusion Middleware A-Team member Greg Mally. "Although the integrations with these adapters are easy and feature rich, there can be some challenges from the operations perspective." Greg's post focuses on technical tips for dealing with one of these challenges. Podcast: DevOps and Continuous Integration In Part 1 of a 3-part program, panelists Tim Hall (Senior Director of product management for Oracle Enterprise Repository and Oracle’s Application Integration Architecture), Robert Wunderlich (Principal Product Manager for Oracle’s Application Integration Architecture Foundation Pack) and Peter Belknap (Director of product management for Oracle SOA Integration) discuss why DevOps matters and how it changes development methodologies and organizational structure. Good To Know - Conflicting View Objects and Shared Entity | Andrejus Baranovskis Oracle ACE Director Andrejus Baranovskis shares his thoughts -- and a sample application -- dealing with an "interesting ADF behavior" encountered over the weekend. Cloud Deployment Models | B. R. Clouse Looking out for the cloud newbies... "As the cloud paradigm grows in depth and breadth, more readers are approaching the topic for the first time, or from a new perspective," says B. R. Clouse. "This blog is a basic review of cloud deployment models, to help orient newcomers and neophytes." Service governance morphs into cloud API management | David Linthicum "When building and using clouds, the ability to manage APIs or services is the single most important item you can provide to ensure the success of the project," says David Linthicum. "But most organizations driving a cloud project for the first time have no experience handling a service-based architecture and don't see the need for API management until after deployment. By then, it's too late." Oracle Fusion Middleware Security: Password Policy in OAM 11g R2 | Rob Otto Rob Otto continues the Oracle Fusion Middleware A-Team "Oracle Access Manager Academy" series with a detailed look at OAM's ability to support "a subset of password management processes without the need to use Oracle Identity Manager and LDAP Sync." Understanding the JSF Lifecycle and ADF Optimized Lifecycle | Steven Davelaar Could you call that a surprise ending? Oracle WebCenter & ADF Architecture Team (A-Team) member learned a lot more than he expected while creating a UKOUG presentation entitled "What you need to know about JSF to be succesful with ADF." Expanding on requestaudit - Tracing who is doing what...and for how long | Kyle Hatlestad "One of the most helpful tracing sections in WebCenter Content (and one that is on by default) is the requestaudit tracing," says Oracle Fusion Middleware A-Team architect Kyle Hatlestad. Get up close and technical in his post. Thought for the Day "There is no code so big, twisted, or complex that maintenance can't make it worse." — Gerald Weinberg Source: SoftwareQuotes.com

Come see us at JavaU at JavaOne!

- by tmcginn

In just a little under a month, JavaOne will be in full swing (no pun intended) and thousands of Java developers will gather to hear the latest Java news, immerse themselves in Java technology and learn some new things. This year, I am fortunate enough to be able to attend, along with my Java curriculum development colleagues Matt Heimer and Mike Williams. We start our week at JavaOne teaching a one-day session at JavaU on Sunday morning. If you have never attended a training session through JavaU, you should check it out. There are some terrific sessions this year, and it might help to justify your trip to JavaOne if you can say it was for training! This year I am teaching a one day session on Java SE 7 New Features - a great session for anyone interested in the specific details of what is new in Java SE 7. Matt is teaching a one-day session on Developing Portable Java EE applications with the Enterprise JavaBeans 3.1 API and Java Persistence 2.0 API EJB, and Mike is doing a one-day session on developing Rich Client applications with Java SE 7 using Java FX 2. I asked Matt and Mike to tell me what developers can expect from their sessions. Matt: "My session will get you up to speed on everything you need to know to create portable Java EE 6 applications using EJB 3.1 and JPA 2. I am going to cover why everyone can benefit from using EJBs (and why developers should relearn them if they haven't looked at them for years). Students who attend my session will see JPA examples showcasing how to use relational databases in an enterprise applications without programming to JDBC and without writing SQL statements. EJB and JPA benefit from being paired together, so I will also show how transaction management is easier in a container. I encourage students to bring a laptop and code as they learn!" Mike: "My session covers how to develop a rich client application using Java FX 2. Starting with the basic concepts of JavaFX, students will see how a JavaFX application is built from its layout, to its controls, to its data structures. In addition, more advanced controls like charts, smart tables, and transitions will be added to the application. Finally, a quick review of JavaFX concurrency and data binding is included. Blended with the core concepts the session will include some of the latest JavaFX technology. This includes using Scene Builder to create a JavaFX UI and connecting your XML UI definition to Java code. In addition, packaging of the JavaFX application will be covered with some examples of the new native packaging features." As I mentioned, my session covers the changes in the Java for SE 7, including the language changes that were voted into Java SE 7 from Project Coin. I will also look at how you can take advantage if the the new I/O library (NIO.2) for writing applications that work with files, directories and file systems. We will also look at the changes in Asynchronous I/O that are a part of the changes in NIO/2. We will spend some time looking at the changes to the Java Virtual Machine as well, including support for dynamically typed languages (JSR-292). We will spend some time looking at the Java Concurrency enhancements (JSR-166), including the new Fork/Join framework. And we'll round out the day with a look at changes in Swing, XML and a number of smaller changes in the API's. And, if these topics aren't grabbing your interest, take a look at the other 10 sessions that range from topics on architecture to how to pass the Oracle Certified Programmer I and II exams. See you soon!

Protecting Consolidated Data on Engineered Systems

- by Steve Enevold

In this time of reduced budgets and cost cutting measures in Federal, State and Local governments, the requirement to provide services continues to grow. Many agencies are looking at consolidating their infrastructure to reduce cost and meet budget goals. Oracle's engineered systems are ideal platforms for accomplishing these goals. These systems provide unparalleled performance that is ideal for running applications and databases that traditionally run on separate dedicated environments. However, putting multiple critical applications and databases in a single architecture makes security more critical. You are putting a concentrated set of sensitive data on a single system, making it a more tempting target. The environments were previously separated by iron so now you need to provide assurance that one group, department, or application's information is not visible to other personnel or applications resident in the Exadata system. Administration of the environments requires formal separation of duties so an administrator of one application environment cannot view or negatively impact others. Also, these systems need to be in protected environments just like other critical production servers. They should be in a data center protected by physical controls, network firewalls, intrusion detection and prevention, etc Exadata also provides unique security benefits, including a reducing attack surface by minimizing packages and services to only those required. In addition to reducing the possible system areas someone may attempt to infiltrate, Exadata has the following features: 1. Infiniband, which functions as a secure private backplane 2. IPTables to perform stateful packet inspection for all nodes Cellwall implements firewall services on each cell using IPTables 3. Hardware accelerated encryption for data at rest on storage cells Oracle is uniquely positioned to provide the security necessary for implementing Exadata because security has been a core focus since the company's beginning. In addition to the security capabilities inherent in Exadata, Oracle security products are all certified to run in an Exadata environment. Database Vault Oracle Database Vault helps organizations increase the security of existing applications and address regulatory mandates that call for separation-of-duties, least privilege and other preventive controls to ensure data integrity and data privacy. Oracle Database Vault proactively protects application data stored in the Oracle database from being accessed by privileged database users. A unique feature of Database Vault is the ability to segregate administrative tasks including when a command can be executed, or that the DBA can manage the health of the database and objects, but may not see the data Advanced Security helps organizations comply with privacy and regulatory mandates by transparently encrypting all application data or specific sensitive columns, such as credit cards, social security numbers, or personally identifiable information (PII). By encrypting data at rest and whenever it leaves the database over the network or via backups, Oracle Advanced Security provides the most cost-effective solution for comprehensive data protection. Label Security is a powerful and easy-to-use tool for classifying data and mediating access to data based on its classification. Designed to meet public-sector requirements for multi-level security and mandatory access control, Oracle Label Security provides a flexible framework that both government and commercial entities worldwide can use to manage access to data on a "need to know" basis in order to protect data privacy and achieve regulatory compliance Data Masking reduces the threat of someone in the development org taking data that has been copied from production to the development environment for testing, upgrades, etc by irreversibly replacing the original sensitive data with fictitious data so that production data can be shared safely with IT developers or offshore business partners Audit Vault and Database Firewall Oracle Audit Vault and Database Firewall serves as a critical detective and preventive control across multiple operating systems and database platforms to protect against the abuse of legitimate access to databases responsible for almost all data breaches and cyber attacks. Consolidation, cost-savings, and performance can now be achieved without sacrificing security. The combination of built in protection and Oracle’s industry-leading data protection solutions make Exadata an ideal platform for Federal, State, and local governments and agencies.

The Linux powered LAN Gaming House

- by sachinghalot

LAN parties offer the enjoyment of head to head gaming in a real-life social environment. In general, they are experiencing decline thanks to the convenience of Internet gaming, but Kenton Varda is a man who takes his LAN gaming very seriously. His LAN gaming house is a fascinating project, and best of all, Linux plays a part in making it all work.Varda has done his own write ups (short, long), so I'm only going to give an overview here. The setup is a large house with 12 gaming stations and a single server computer.The client computers themselves are rack mounted in a server room, and they are linked to the gaming stations on the floor above via extension cables (HDMI for video and audio and USB for mouse and keyboard). Each client computer, built into a 3U rack mount case, is a well specced gaming rig in its own right, sporting an Intel Core i5 processor, 4GB of RAM and an Nvidia GeForce 560 along with a 60GB SSD drive.Originally, the client computers ran Ubuntu Linux rather than Windows and the games executed under WINE, but Varda had to abandon this scheme. As he explains on his site:"Amazingly, a majority of games worked fine, although many had minor bugs (e.g. flickering mouse cursor, minor rendering artifacts, etc.). Some games, however, did not work, or had bad bugs that made them annoying to play."Subsequently, the gaming computers have been moved onto a more conventional gaming choice, Windows 7. It's a shame that WINE couldn't be made to work, but I can sympathize as it's rare to find modern games that work perfectly and at full native speed. Another problem with WINE is that it tends to suffer from regressions, which is hardly surprising when considering the difficulty of constantly improving the emulation of the Windows API. Varda points out that he preferred working with Linux clients as they were easier to modify and came with less licensing baggage.Linux still runs the server and all of the tools used are open source software. The hardware here is a Intel Xeon E3-1230 with 4GB of RAM. The storage hanging off this machine is a bit more complex than the clients. In addition to the 60GB SSD, it also has 2x1TB drives and a 240GB SDD.When the clients were running Linux, they booted over PXE using a toolchain that will be familiar to anyone who has setup Linux network booting. DHCP pointed the clients to the server which then supplied PXELINUX using TFTP. When booted, file access was accomplished through network block device (NBD). This is a very easy to use system that allows you to serve the contents of a file as a block device over the network. The client computer runs a user mode device driver and the device can be mounted within the file system using the mount command.One snag with offering file access via NBD is that it's difficult to impose any security restrictions on different areas of the file system as the server only sees a single file. The advantage is perfomance as the client operating system simply sees a block device, and besides, these security issues aren't relevant in this setup.Unfortunately, Windows 7 can't use NBD, so, Varda had to switch to iSCSI (which works in both server and client mode under Linux). His network cards are not compliant with this standard when doing a netboot, but fortunately, gPXE came to the rescue, and he boostraps it over PXE. gPXE is also available as an ISO image and is worth knowing about if you encounter an awkward machine that can't manage a network boot. It can also optionally boot from a HTTP server rather than the more traditional TFTP server.According to Varda, booting all 12 machines over the Gigabit Ethernet network is surprisingly fast, and once booted, the machines don't seem noticeably slower than if they were using local storage. Once loaded, most games attempt to load in as much data as possible, filling the RAM, and the the disk and network bandwidth required is small. It's worth noting that these are aspects of this project that might differ from some other thin client scenarios.At time of writing, it doesn't seem as though the local storage of the client machines is being utilized. Instead, the clients boot into Windows from an image on the server that contains the operating system and the games themselves. It uses the copy on write feature of LVM so that any writes from a client are added to a differencing image allocated to that client. As the administrator, Varda can log into the Linux server and authorize changes to the master image for updates etc.SummaryOverall, Varda estimates the total cost of the project at about $40,000, and of course, he needed a property that offered a large physical space in order to house the computers and the gaming workstations. Obviously, this project has stark differences to most thin client projects. The balance between storage, network usage, GPU power and security would not be typical of an office installation, for example. The only letdown is that WINE proved to be insufficiently compatible to run a wide variety of modern games, but that is, perhaps, asking too much of it, and hats off to Varda for trying to make it work.

Windows Azure Recipe: Consumer Portal

- by Clint Edmonson

Nearly every company on the internet has a web presence. Many are merely using theirs for informational purposes. More sophisticated portals allow customers to register their contact information and provide some level of interaction or customer support. But as our understanding of how consumers use the web increases, the more progressive companies are taking advantage of social web and rich media delivery to connect at a deeper level with the consumers of their goods and services. Drivers Cost reduction Scalability Global distribution Time to market Solution Here’s a sketch of how a Windows Azure Consumer Portal might be built out: Ingredients Web Role – this will host the core of the solution. Each web role is a virtual machine hosting an application written in ASP.NET (or optionally php, or node.js). The number of web roles can be scaled up or down as needed to handle peak and non-peak traffic loads. Database – every modern web application needs to store data. SQL Azure databases look and act exactly like their on-premise siblings but are fault tolerant and have data redundancy built in. Access Control (optional) – if identity needs to be tracked within the solution, the access control service combined with the Windows Identity Foundation framework provides out-of-the-box support for several social media platforms including Windows LiveID, Google, Yahoo!, Facebook. It also has a provider model to allow integration with other platforms as well. Caching (optional) – for sites with high traffic with lots of read-only data and lists, the distributed in-memory caching service can be used to cache and serve up static data at higher scale and speed than direct database requests. It can also be used to manage user session state. Blob Storage (optional) – for sites that serve up unstructured data such as documents, video, audio, device drivers, and more. The data is highly available and stored redundantly across data centers. Each entry in blob storage is provided with it’s own unique URL for direct access by the browser. Content Delivery Network (CDN) (optional) – for sites that service users around the globe, the CDN is an extension to blob storage that, when enabled, will automatically cache frequently accessed blobs and static site content at edge data centers around the world. The data can be delivered statically or streamed in the case of rich media content. Training Labs These links point to online Windows Azure training labs where you can learn more about the individual ingredients described above. (Note: The entire Windows Azure Training Kit can also be downloaded for offline use.) Windows Azure (16 labs) Windows Azure is an internet-scale cloud computing and services platform hosted in Microsoft data centers, which provides an operating system and a set of developer services which can be used individually or together. It gives developers the choice to build web applications; applications running on connected devices, PCs, or servers; or hybrid solutions offering the best of both worlds. New or enhanced applications can be built using existing skills with the Visual Studio development environment and the .NET Framework. With its standards-based and interoperable approach, the services platform supports multiple internet protocols, including HTTP, REST, SOAP, and plain XML SQL Azure (7 labs) Microsoft SQL Azure delivers on the Microsoft Data Platform vision of extending the SQL Server capabilities to the cloud as web-based services, enabling you to store structured, semi-structured, and unstructured data. Windows Azure Services (9 labs) As applications collaborate across organizational boundaries, ensuring secure transactions across disparate security domains is crucial but difficult to implement. Windows Azure Services provides hosted authentication and access control using powerful, secure, standards-based infrastructure. See my Windows Azure Resource Guide for more guidance on how to get started, including links web portals, training kits, samples, and blogs related to Windows Azure.

Information on upgrading Kinect Applications to MS SDK Beta 2.

- by mbcrump

Introduction Microsoft recently released the Kinect for Windows SDK Beta 2. It contains many enhancements and fixes that can be found here. The only problem with it is that a lot of current demo applications no longer function properly. Today, I’m going to walk you through a typical scenario of upgrading a Kinect application built with Beta 1 to Beta 2. Note: This tutorial covers WPF, but you can use the same techniques for WinForms. 1) Fix the references Let’s start with a fairly popular Kinect demo called Kinect User Interface Demo. This project uses the beta 1 version of Microsoft.Research.Kinect.dll and version 1.0.0.0 of Coding4Fun’s Kinect library. After you download the source code and extract the zip you will see the following references in Visual Studio 2010: Pay attention to the following references as these are the .dlls that you will have to update: Coding4Fun.Kinect.Wpf Microsoft.Research.Kinect If you click on Coding4Fun.Kinect.Wpf file you will see the following version information (v1.0.0.0): This needs to be upgraded to the Coding4Fun Kinect library built against Beta 2. So head over to http://c4fkinect.codeplex.com/ and hit download and you will have the following files. Go ahead and hit the delete key on your keyboard to remove the Coding4Fun.Kinect.Wpf.dll file from your project. Select “Add Reference” and navigate out to the folder where you extracted the files and select Coding4Fun.Kinect.Wpf.dll. If you click on the Coding4Fun.Kinect.Wpf.dll file and check properties it should be listed at 1.1.0.0: Fix Microsoft.Research.Kinect.dll The official SDK Beta 2 released a new .dll that you will need to reference in your application. Go ahead and select Microsoft.Research.Kinect.dll in your application and hit the Delete key on your keyboard. Go ahead and select Add Reference again and select Microsoft.Research.Kinect.dll from the .NET tab. Double check and make sure the version number is 1.0.0.45 as shown below. References fixed – Runtime needs to be updated. So we have fixed the references in a typical Kinect application that uses Microsoft’s SDK and C4F Kinect libraries. Now, we will need to update the runtime. All Beta 1 Kinect applications will instantiate the Runtime with the following code: Can you see that it is now marked with [Depreciated]? That means we need to update it before Microsoft decides to remove it from future versions of the SDK. We can fix this very easily by replacing this code: readonly Runtime _runtime = new Runtime(); with Microsoft.Research.Kinect.Nui.Runtime _nui; and adding similar code to our Loaded event as shown below public MainWindow() { InitializeComponent(); Loaded += new RoutedEventHandler(MainWindow_Loaded); } void MainWindow_Loaded(object sender, RoutedEventArgs e) { if (Runtime.Kinects.Count == 0) { txtInfo.Text = "Missing Kinect"; } else { _nui = Runtime.Kinects[0]; _nui.Initialize(RuntimeOptions.UseColor); // Video Frame Ready Event can happen now!!! //_nui.VideoFrameReady += new EventHandler<ImageFrameReadyEventArgs>(_nui_VideoFrameReady); _nui.VideoStream.Open(ImageStreamType.Video, 2, ImageResolution.Resolution640x480, ImageType.Color); } } In this sample, I am testing to see if a Kinect is detected and if it is then I initialize the runtime with my first Kinect by using the Runtime.Kinects[0]. You can also specify other Kinect devices here. The rest of the code is standard code that you simply modify however you wish (ie Skeletal, Depth, etc) depending on what type of video feed you want. Conclusion As you can see it really wasn’t that painful to upgrade your project to Beta 2. I would recommend that you go ahead and upgrade to Beta 2 as future versions of the SDK will use these methods. Thanks for reading. Subscribe to my feed

Utility to Script SQL Server Configuration

- by Bill Graziano

I wrote a small utility to script some key SQL Server configuration information. I had two goals for this utility: Assist with disaster recovery preparation Identify configuration changes I’ve released the application as open source through CodePlex. You can download it from CodePlex at the Script SQL Server Configuration project page. The application is a .NET 2.0 console application that uses SMO. It writes its output to a directory that you specify. Disaster Planning ScriptSqlConfig generates scripts for logins, jobs and linked servers. It writes the properties and configuration from the instance to text files. The scripts are designed so they can be run against a DR server in the case of a disaster. The properties and configuration will need to be manually compared. Each job is scripted to its own file. Each linked server is scripted to its own file. The linked servers don’t include the password if you use a SQL Server account to connect to the linked server. You’ll need to store those somewhere secure. All the logins are scripted to a single file. This file includes windows logins, SQL Server logins and any server role membership. The SQL Server logins are scripted with the correct SID and hashed passwords. This means that when you create the login it will automatically match up to the users in the database and have the correct password. This is the only script that I programmatically generate rather than using SMO. The SQL Server configuration and properties are scripted to text files. These will need to be manually reviewed in the event of a disaster. Or you could DIFF them with the configuration on the new server. Configuration Changes These scripts and files are all designed to be checked into a version control system. The scripts themselves don’t include any date specific information. In my environments I run this every night and check in the changes. I call the application once for each server and script each server to its own directory. The process will delete any existing files before writing new ones. This solved the problem I had where the scripts for deleted jobs and linked servers would continue to show up. To see any changes I just need to query the version control system to show many any changes to the files. Database Scripting Utilities that script database objects are plentiful. CodePlex has at least a dozen of them including one I wrote years ago. The code is so easy to write it’s hard not to include that functionality. This functionality wasn’t high on my list because it’s included in a database backup. Unless you specify the /nodb option, the utility will script out many user database objects. It will script one object per file. It will script tables, stored procedures, user-defined data types, views, triggers, table types and user-defined functions. I know there are more I need to add but haven’t gotten around it yet. If there’s something you need, please log an issue and get it added. Since it scripts one object per file these really aren’t appropriate to recreate an empty database. They are really good for checking into source control every night and then seeing what changed. I know everyone tells me all their database objects are in source control but a little extra insurance never hurts. Conclusion I hope this utility will help a few of you out there. My goal is to have it script all server objects that aren’t contained in user databases. This should help with configuration changes and especially disaster recovery.

Building Tag Cloud Declarative ADF Component

- by Arunkumar Ramamoorthy

When building a website, there could a requirement to add a tag cloud to let the users know the popular tags (or terms) used in the site. In this blog, we would build a simple declarative component to be used as tag cloud in the page. To start with, we would first create the declarative component, which could display the tag cloud. We will do that by creating a new custom application from the new gallery. Give a name for the app and the project and from the new gallery, let us create a new ADF Declarative Component We need to specify the name for the declarative component, attributes in it etc. as follows For displaying the tags as cloud, we need to pass the content to this component. So, we will create an attribute to hold the values for the tag. Let us name it as "value" and make it as java.lang.String type. Once after this, to hold the component, we need to create a tag library. This can be done by clicking on the Add Tag Library button. Clicking on OK buttons in all the open dialogs would create a declarative component for us. Now, we need to display the tag cloud based on the value passed to the component. To do that, we assume that the value is a Tree Binding and has two attributes in it, say "Name" and "Weight". To make a tag cloud, we would put together the "Name" in a loop and set it's font size based on the "Weight". After putting our logic to work, here is how the source look Attributes added to the declarative components can be retrieved by using #{attrs.<attribute_name>}. Now, we need to deploy this project as ADF Library Jar file, so that this can be distributed to the consuming applications. We'll select ADF Library Jar as type and create the profile. We would be getting the jar file after deployment. To test the functionality, we could create a simple Fusion Web Application. To add our custom component to the consuming application, we can create a file system connection pointing to the location where the jar file is and add it or, add through the project properties of the ViewController project. Now, our custom component has been added to the consuming application. We could test that by creating a VO in the model project with a query like, select 'Faces' as Name,25 as Weight from dual union all select 'ADF', 15 from dual union all select 'ADFdi', 30 from dual union all select 'BC4J', 20 from dual union all select 'EJB', 40 from dual union all select 'WS', 35 from dual Add this VO to the AppModule, so that it would be exposed to the data control. Then, we could create a jspx page, and add a tree binding to the VO created. We can now see our Tag Cloud declarative component is available in the component palette. It can be inserted from the component palette to our page and set it's value property to CollectionModel of the tree binding created. Now that we've created the Declarative component and added that to our page successfully, we can run the page to see how it looks. As per the query, the Tags are displayed in different fonts, based on their weight.

The new Silverlight 5 beta will be available during the starting quarter of the next year with new capabilities and lot of new features. Silverlight 5 will be powerful development platform for both web-based business apps and rich media solutions. We can expect final version of Silverlight 5 on end of 2011. Windows Phone 7 Development Tools Mobile application development will be very hot in year 2011 and Windows Phone 7 will be one of the hottest technologies of next year. You can get introduction on Windows Phone 7 Development Tools from somasegar’s blog post and MSDN documentation available from here. EF Code First I am a big fan of Entity Framework’s Code First approach and hope that Code First approach will attract more people onto Entity Framework 4. EF Code First lets you focus on domain model which will enable Domain-Driven Development for applications. I hope that DDD fans will love the EF Code First approach. The Entity Framework 4 now supports three types of approaches and these will attract different types of developer audience. ASP.NET MVC 3 The ASP.NET MVC 3 will be the hottest technology of Microsoft web stack on the next year. ASP.NET developers will widely move to the ASP.NET MVC Framework from their WebForms development. The new Razor view engine is great and it will increase the adoption of ASP.NET MVC 3. Razor the will improve the productivity when working with ASP.NET MVC 3 Views. You can build great web applications using ASP.NET MVC 3 and jQuery with better maintainability, generation of clean HTML and even better performance. In my opinion, the best technology stack for web development is ASP.NET MVC 3 and Entity Framework 4 Code First as ORM. On the next year, you can expect more articles from my blog on ASP.NET MVC 3 and Entity Framework 4 Code First. RavenDB NoSQL and Document databases will get more attention on the coming year and RavenDB will be the most notable document database in the .NET stack. RavenDB is an Open Source (with a commercial option) document database for the .NET/Windows platform developed by Ayende Rahien. RavenDB is .NET focused document database which comes with a fully functional .NET client API and supports LINQ. I have written few articles on RavenDB and you can read it from here. Managed Extensibility Framework (MEF) Many people didn't realized the power of MEF. The MEF lets you create extensible applications and provides a great solution for the runtime extensibility problem. I hope that .NET developers will more adopt the MEF on the next year for their .NET applications. You can get an excellent introduction on MEF from Anoop Madhusudanan’s blog post MEF or Managed Extensibility Framework – Creating a Zoo and Animals

Migrating Virtual Iron guest to Oracle VM 3.x

- by scoter

As stated on the official site, Oracle in 2009, acquired a provider of server virtualization management software named Virtual Iron; you can find all the acquisition details at this link. Into the FAQ on the official site you can also view that, for the future, Oracle plans to fully integrate Virtual Iron technology into Oracle VM products, and any enhancements will be delivered as a part of the combined solution; this is what is going on with Oracle VM 3.x. So, customers started asking us to migrate Virtual Iron guests to Oracle VM. IMPORTANT: This procedure needs a dedicated OVM-Server with no-guests running on top; be careful while execute this procedure on production environments. In these little steps you will find how-to migrate, as fast as possible, your guests between VI ( Virtual Iron ) and Oracle VM; keep in mind that OracleVM has a built-in P2V utility ( Official Documentation ) that you can use to migrate guests between VI and Oracle VM. Concepts: VI repositories. On VI we have the same "repository" concept as in Oracle VM; the difference between these two products is that VI use a raw-lun as repository ( instead of using ocfs2 and its capabilities, like ref-links ). The VI "raw-lun" repository, with a pure operating-system perspective, may be presented as in this picture: Infact on this "raw-lun" VI create an LVM2 volume-group. The VI "raw-lun" repository, with an hypervisor perspective, may be presented as in this picture: So, the relationships are: LVM2-Volume-Group <-> VI Repository LVM2-Logical-Volume <-> VI guest virtual-disk The first step is to present the VI repository ( raw-lun ) to your dedicated OVM-Server. Prepare dedicated OVM-Server On the OVM-Server ( OVS ) you need to discover new lun and, after that, discover volume-group and logical-volumes containted in VI repository; due to default OVS configuration you need to edit lvm2 configuration file: /etc/lvm/lvm.conf # By default for OVS we restrict every block device: # filter = [ "r/.*/" ] and comment the line starting with "filter" as above. Now you have to discover the raw-lun presented and, next, activate volume-group and logical-volumes: #!/bin/bash for HOST in `ls /sys/class/scsi_host`;do echo '- - -' > /sys/class/scsi_host/$HOST/scan; done CPATH=`pwd` cd /dev for DEVICE in `ls sd[a-z] sd?[a-z]`;do echo '1' > /sys/block/$DEVICE/device/rescan; done cd $CPATH cd /dev/mapper for PARTITION in `ls *[a-z] *?[a-z]`;do partprobe /dev/mapper/$PARTITION; done cd $CPATH vgchange -a yAfter that you will see a new device:[root@ovs01 ~]# cd /dev/6000F4B00000000000210135bef64994[root@ovs01 6000F4B00000000000210135bef64994]# ls -l 6000F4B0000000000061013* lrwxrwxrwx 1 root root 77 Oct 29 10:50 6000F4B00000000000610135c3a0b8cb -> /dev/mapper/6000F4B00000000000210135bef64994-6000F4B00000000000610135c3a0b8cb By your OVM-Manager create a guest server with the same definition as on VI:same core number as VI source guestsame memory as VI source guestsame number of disks as VI source guest ( you can create OVS virtual disk with a small size of 1GB because the "clone" will, eventually, extend the size of your new virtual disks )Summarizing:source-virtual-disk path ( VI ):/dev/mapper/6000F4B00000000000210135bef64994-6000F4B00000000000610135c3a0b8cbdest-virtual-disk path ( OVS ):/OVS/Repositories/0004fb00000300006cfeb81c12f12f00/VirtualDisks/0004fb000012000055e0fc4c5c8a35ee.img ** ** = to identify your virtual disk you have verify its name under the "vm.cfg" file of your new guest.Clone VI virtual-disk to OVS virtual-diskdd if=/dev/mapper/6000F4B00000000000210135bef64994-6000F4B00000000000610135c3a0b8cb of=/OVS/Repositories/0004fb00000300006cfeb81c12f12f00/VirtualDisks/0004fb000012000055e0fc4c5c8a35ee.img Clean unsupported parameters and changes on OVS.1.

Then based on 1: a) deleting web.config and renaming should only happen if code in destination is new b) Robocopy should not override files if they are the same I think there is /Xo option to do that any idea how to achieve that? :)

Web Services Example - Part 1: Declarative

- by Denis T

In this edition of the ADF Mobile blog we'll tackle part 1 of our Web Service examples. In this posting we'll take a look at using a declarative SOAP Web Service. Getting the sample code: Just click here to download a zip of the entire project. You can unzip it and load it into JDeveloper and deploy it either to iOS or Android. Please follow the previous blog posts if you need help getting JDeveloper or ADF Mobile installed. Defining our Web Service: First off, we should mention that this sample code is using a public web service provided free by CDYNE Corporation that provides weather forecasts by zipcode. Sometimes this service goes down so please ensure you know it's up before reporting this example isn't working. Let's take a look at the web service. We created this by using the "Web Service Data Control" from the New Gallery and using this link to this wsdl: "http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL" This web service has several methods but we're interested in GetCityForecastByZIP which takes a single string parameter for the zipcode and the second method, GetWeatherInformation that enumerates all possible forecast descriptions and associated image URLs. The latter we'll use in the next edition but we included it here for completeness. Defing the Application: After adding a feature to the adfmf-feature.xml file, we added a taskflow to host the application flow. This comprises of a home screen with a list with items for each method in the web service, "Forecast by Zip" and "Weather Info". In this application we've also decided to hide the navigation bar since there is only one feature in the application. Forecast by Zip: The "Forecast By ZIP" option first presents the user with a screen where they can enter a zipcode and when the "Search" button is tapped, it executes the GetCityForecastByZIP method. This is done by binding an Action binding to that method. The easiest way to accomplish this is to just drag & drop the method from the Data Control palette to the AMX page and drop it as a button and let the framework hook it up for you. There is an inputText component on the page that is bound to a pageFlowScope variable called "zip". This is used as the parameter to the Action binding when it is executed. Because the actionListener attribute of the commandButton executes the Web Service each time, we ensure that the method is invoked every time the button is clicked. Weather Info: Unlike the previous method, this time instead of explictly executing the web service method we are using deferred invocation. What this means is that we will bind to the results of the method and the framework will execute the method when it the data is required to be rendered. We do this by simply doing a drag & drop of the results of the GetWeatherInformation to the AMX page. When the page is rendered and the bindings are resolved the framework invokes the method. This executes the method only when it is needed and fills the Data Control provider. Because we never re-execute the method, you can click from Home to Weather Info and back many times and the web service is only ever invoked once. Issues and Possible Improvements: One thing you will quickly realize with this example is that the error handling is done by the framework for you. For simple examples this is fine but for real applications you'll want to customize these error messages. With the declarative invocation of web services, this is difficult. This is one aspect we'll address in the second installment of the web service examples where we will show you how to do programmatic invocation which allows you better error handling. Another issue you will notice with this example is that we can enumerate the weather information but there isn't an easy way to use that information to show the corresponding description and image as part of the forecast results. We'll show you how to do this in the next example.

Configuring nginx server to handle requests from multiple domains

- by KillABug

Use Case:- I am working on a web application which allows to create HTML templates and publish them on amazon S3.Now to publish the websites I use nginx as a proxy server. What the proxy server does is,when a user enters the website URL,I want to identify how to check if the request comes from my application i.e app.mysite.com(This won't change) and route it to apache for regular access,if its coming from some other domain like a regular URL www.mysite.com(This needs to be handled dynamically.Can be random) it goes to the S3 bucket that hosts the template. My current configuration is: user nginx; worker_processes 1; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; charset utf-8; keepalive_timeout 65; server_tokens off; sendfile on; tcp_nopush on; tcp_nodelay off; Default Server Block to catch undefined host names server { listen 80; server_name app.mysite.com; access_log off; error_log off; location / { proxy_pass http://127.0.0.1:8080; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_redirect off; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; client_max_body_size 10m; client_body_buffer_size 128k; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; } } } Load all the sites include /etc/nginx/conf.d/*.conf; Updates as I was not clear enough :- My question is how can I handle both the domains in the config file.My nginx is a proxy server on port 80 on an EC2 instance.This also hosts my application that runs on apache on a differnet port.So any request coming for my application will come from a domain app.mysite.com and I also want to proxy the hosted templates on S3 which are inside a bucket say sites.mysite.com/coolsite.com/index.html.So if someone hits coolsite.com I want to proxy it to the folder sites.mysite.com/coolsite.com/index.html and not to app.syartee.com.Hope I am clear The other server block: # Server for S3 server { # Listen on port 80 for all IPs associated with your machine listen 80; # Catch all other server names server_name _; //I want it to handle other domains then app.mysite.com # This code gets the host without www. in front and places it inside # the $host_without_www variable # If someone requests www.coolsite.com, then $host_without_www will have the value coolsite.com set $host_without_www $host; if ($host ~* www\.(.*)) { set $host_without_www $1; } location / { # This code rewrites the original request, and adds the host without www in front # E.g. if someone requests # /directory/file.ext?param=value # from the coolsite.com site the request is rewritten to # /coolsite.com/directory/file.ext?param=value set $foo 'http://sites.mysite.com'; # echo "$foo"; rewrite ^(.*)$ $foo/$host_without_www$1 break; # The rewritten request is passed to S3 proxy_pass http://sites.mysite.com; include /etc/nginx/proxy_params; } } Also I understand I will have to make the DNS changes in the cname of the domain.I guess I will have to add app.mysite.com under the CNAME of the template domain name?Please correct if wrong. Thank you for your time

Searching for context in Silverlight applications

- by PeterTweed

A common behavior in business applications that have developed through the ages is for a user to be able to get information or execute commands in relation to some information/function displayed by right clicking the object in question and popping up a context menu that offers relevant options to choose. The Silverlight Toolkit April 2010 release introduced the context menu object. This can be added to other UI objects and display options for the user to choose. The menu items can be enabled or disabled as per your application logic and icons can be added to the menu items to add visual effect. This post will walk you through how to use the context menu object from the Silverlight Toolkit. Steps: 1. Create a new Silverlight 4 application 2. Copy the following namespace definition to the user control object of the MainPage.xaml file: xmlns:my="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Input.Toolkit" 3. Copy the following XAML into the LayoutRoot grid in MainPage.xaml: <Border CornerRadius="15" Background="Blue" Width="400" Height="100"> <TextBlock Foreground="White" FontSize="20" Text="Context Menu In This Border...." HorizontalAlignment="Center" VerticalAlignment="Center" > </TextBlock> <my:ContextMenuService.ContextMenu> <my:ContextMenu > <my:MenuItem Header="Copy" Click="CopyMenuItem_Click" Name="copyMenuItem"> <my:MenuItem.Icon> <Image Source="copy-icon-small.png"/> </my:MenuItem.Icon> </my:MenuItem> <my:Separator/> <my:MenuItem Name="pasteMenuItem" Header="Paste" Click="PasteMenuItem_Click"> <my:MenuItem.Icon> <Image Source="paste-icon-small.png"/> </my:MenuItem.Icon> </my:MenuItem> </my:ContextMenu> </my:ContextMenuService.ContextMenu> </Border> The above code associates a context menu with two menu items and a separator between them to the border object. The menu items has icons associated with them to add visual appeal. The menu items have click event handlers that will be added in the MainPage.xaml.cs code behind in a later step. 4. Add two icon sized images to the ClientBin directory of the web project hosting the Silverlight application, named copy-icon-small.png and paste-icon-small.jpg respectively. I used copy and paste icons as the names suggest. 5. Add the following code to the class in MainPage.xaml.cs file: private void CopyMenuItem_Click(object sender, RoutedEventArgs e) { MessageBox.Show("Copy selected"); } private void PasteMenuItem_Click(object sender, RoutedEventArgs e) { MessageBox.Show("Paste selected"); } This code adds the event handlers for the menu items defined in step 3. 6. Run the application, right click on the border and select a menu option and see the appropriate message box displayed. Congratulations it’s that easy!

website connection reset on first load

- by Tar

i'm using nginx with php-cgi. lately a problem has arose where if you don't view my site for a while, like 3-4 minutes, and then open it again, the first request you send will return connection reset by peer in the browser. if you refresh, operation is normal for all subsequent requests. this happens every time and it isn't just an isolated incident, it happens to everyone using my site. i've tried to restart nginx and php-cgi but to no avail. does anyone know what the problem could be? i can provide whatever information necessary. it's worth noting that there's nothing in error log besides that message about client closing the connection early. nginx.conf user nobody; worker_processes 4; error_log /var/log/nginx/error.log; pid /var/run/nginx.pid; events { worker_connections 2048; } http { include /etc/nginx/mime.types; error_page 404 /404.html; error_page 403 /403.html; error_page 444 /444.html; error_page 502 /502.html; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; large_client_header_buffers 8 8k; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 30; server_tokens off; gzip on; gzip_proxied any; gzip_comp_level 6; gzip_buffers 64 8k; gzip_min_length 1024; gzip_http_version 1.1; gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; include /etc/nginx/conf.d/*.conf; } default.conf server { listen 80; server_name domain.com; error_log /var/log/nginx/error.log debug; access_log /var/log/nginx/access.log; location / { if ($request_method !~ ^(GET|HEAD|POST)$ ) { return 444; } if ($http_user_agent ~* Havij|hvj|acunetix|wget|HTtrack) { return 403; } root /home/admin06/public_html; autoindex off; index index.php; # Images and static content is treated different location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|xml)$ { access_log off; expires 30d; root /home/admin06/public_html; } location /nginx_status { stub_status on; access_log off;] deny all; } location ~ \.php$ { fastcgi_split_path_info ^(.+\.php)(/.*)$; #try_files $uri =404; fastcgi_pass backend; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /home/site/public_html$fastcgi_script_name; include fastcgi_params; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_intercept_errors on; fastcgi_ignore_client_abort off; fastcgi_connect_timeout 60; fastcgi_send_timeout 60; fastcgi_read_timeout 60; fastcgi_buffer_size 128k; fastcgi_buffers 4 256k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; } ## Disable viewing .htaccess & .htpassword location ~ /\.ht { deny all; } location ~ error_log { deny all; } location ~ access_log { deny all; } location ~ \.cgi { deny all; } location ~ \.db { deny all; } }

Web Service Example - Part 3: Asynchronous

- by Denis T

In this edition of the ADF Mobile blog we'll tackle part 3 of our Web Service examples. In this posting we'll take a look at firing the web service asynchronously and then filling in the UI when it completes. This can be useful when you have data on the device in a local store and want to show that to the user while the application uses lazy loading from a web service to load more data. Getting the sample code: Just click here to download a zip of the entire project. You can unzip it and load it into JDeveloper and deploy it either to iOS or Android. Please follow the previous blog posts if you need help getting JDeveloper or ADF Mobile installed. Note: This is a different workspace than WS-Part2 What's different? In this example, when you click the Search button on the Forecast By Zip option, now it takes you directly to the results page, which is initially blank. When the web service returns a second or two later the data pops into the UI. If you go back to the search page and hit Search it will again clear the results and invoke the web service asynchronously. This isn't really that useful for this particular example but it shows an important technique that can be used for other use cases. How it was done 1) First we created a new class, ForecastWorker, that implements the Runnable interface. This is used as our worker class that we create an instance of and pass to a new thread that we create when the Search button is pressed inside the retrieveForecast actionListener handler. Once the thread is started, the retrieveForecast returns immediately. 2) The rest of the code that we had previously in the retrieveForecast method has now been moved to the retrieveForecastAsync. Note that we've also added synchronized specifiers on both these methods so they are protected from re-entrancy. 3) The run method of the ForecastWorker class then calls the retrieveForecastAsync method. This executes the web service code that we had previously, but now on a separate thread so the UI is not locked. If we had already shown data on the screen it would have appeared before this was invoked. Note that you do not see a loading indicator either because this is on a separate thread and nothing is blocked. 4) The last but very important aspect of this method is that once we update data in the collections from the data we retrieve from the web service, we call AdfmfJavaUtilities.flushDataChangeEvents(). We need this because as data is updated in the background thread, those data change events are not propagated to the main thread until you explicitly flush them. As soon as you do this, the UI will get updated if any changes have been queued. Summary of Fundamental Changes In This Application The most fundamental change is that we are invoking and handling our web services in a background thread and updating the UI when the data returns. This allows an application to provide a better user experience in many cases because data that is already available locally is displayed while lengthy queries or web service calls can be done in the background and the UI updated when they return. There are many different use cases for background threads and this is just one example of optimizing the user experience and generating a better mobile application.

nginx + php-fpm - where are my $_GET params?

- by egis

I have a strange problem here. I just moved from apache + mod_php to nginx + php-fpm. Everything went fine except this one problem. I have a site, let's say example.com. When I access it like example.com?test=get_param $_SERVER['REQUEST_URI'] is /?test=get_param and there is a $_GET['test'] also.

nginx + php-fpm - where are my $_GET params?

- by egis

Hello everyone, I have a strange problem here. I just moved from apache + mod_php to nginx + php-fpm. Everything went fine except this one problem. I have a site, let's say example.com. When I access it like example.com?test=get_param $_SERVER['REQUEST_URI'] is /?test=get_param and there is a $_GET['test'] also. But when I access example.com/ajax/search/?search=get_param $_SERVER['REQUEST_URI'] is /ajax/search/?search=get_param yet there is no $_GET['search'] (there is no $_GET array at all). I'm using Kohana framework. which routes /ajax/search to controller, but I've put phpinfo() at index.php so I'm checking for $_GET variables before framework does anything (this means that disapearing get params aren't frameworks fault). My nginx.conf is like this worker_processes 4; pid logs/nginx.pid; events { worker_connections 1024; } http { index index.html index.php; autoindex on; autoindex_exact_size off; include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 128; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log logs/access.log main; error_log logs/error.log debug; sendfile on; tcp_nopush on; tcp_nodelay off; keepalive_timeout 2; gzip on; gzip_comp_level 2; gzip_proxied any; gzip_types text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript; include sites-enabled/*; } and example.conf is like this server { listen 80; server_name www.example.com; rewrite ^ $scheme://example.com$request_uri? permanent; } server { listen 80; server_name example.com; root /var/www/example/; location ~ /\. { return 404; } location / { try_files $uri $uri/ /index.php; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include /usr/local/nginx/conf/fastcgi_params; } location ~* ^/(modules|application|system) { return 403; } # serve static files directly location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt)$ { access_log off; expires 30d; } } fastcgi_params is like this fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param SCRIPT_NAME $fastcgi_script_name; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx/$nginx_version; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; # PHP only, required if PHP was built with --enable-force-cgi-redirect fastcgi_param REDIRECT_STATUS 200; fastcgi_connect_timeout 60; fastcgi_send_timeout 180; fastcgi_read_timeout 180; fastcgi_buffer_size 128k; fastcgi_buffers 4 256k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; fastcgi_intercept_errors on; fastcgi_param QUERY_STRING $query_string; fastcgi_param PATH_INFO $fastcgi_path_info; What is the problem here?

XNA WP7 Texture memory and ContentManager

- by jlongstreet

I'm trying to get my WP7 XNA game's memory under control and under the 90MB limit for submission. One target I identified was UI textures, especially fullscreen ones, that would never get unloaded. So I moved UI texture loads to their own ContentManager so I can unload them. However, this doesn't seem to affect the value of Microsoft.Phone.Info.DeviceExtendedProperties.GetValue("ApplicationCurrentMemoryUsage"), so it doesn't look like the memory is actually being released. Example: splash screens. In Game.LoadContent(): Application.Instance.SetContentManager("UI"); // set the current content manager for (int i = 0; i < mSplashTextures.Length; ++i) { // load the splash textures mSplashTextures[i] = Application.Instance.Content.Load<Texture2D>(msSplashTextureNames[i]); } // set the content manager back to the global one Application.Instance.SetContentManager("Global"); When the initial load is done and the title screen starts, I do: Application.Instance.GetContentManager("UI").Unload(); The three textures take about 6.5 MB of memory. Before unloading the UI ContentManager, I see that ApplicationCurrentMemoryUsage is at 34.29 MB. After unloading the ContentManager (and doing a full GC.Collect()), it's still at 34.29 MB. But after that, I load another fullscreen texture (for the title screen background) and memory usage still doesn't change. Could it be keeping the memory for these textures allocated and reusing it? edit: very simple test: protected override void LoadContent() { // Create a new SpriteBatch, which can be used to draw textures. spriteBatch = new SpriteBatch(GraphicsDevice); PrintMemUsage("Before texture load: "); // TODO: use this.Content to load your game content here red = this.Content.Load<Texture2D>("Untitled"); PrintMemUsage("After texture load: "); } private void PrintMemUsage(string tag) { Debug.WriteLine(tag + Microsoft.Phone.Info.DeviceExtendedProperties.GetValue("ApplicationCurrentMemoryUsage")); } protected override void Update(GameTime gameTime) { // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); // TODO: Add your update logic here if (count++ == 100) { GC.Collect(); GC.WaitForPendingFinalizers(); PrintMemUsage("Before CM unload: "); this.Content.Dispose(); GC.Collect(); GC.WaitForPendingFinalizers(); PrintMemUsage("After CM unload: "); red = null; spriteBatch.Dispose(); GC.Collect(); GC.WaitForPendingFinalizers(); PrintMemUsage("After SpriteBatch Dispose(): "); } base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); // TODO: Add your drawing code here if (red != null) { spriteBatch.Begin(); spriteBatch.Draw(red, new Vector2(0,0), Color.White); spriteBatch.End(); } base.Draw(gameTime); } This prints something like (it changes every time): Before texture load: 7532544 After texture load: 10727424 Before CM unload: 9875456 After CM unload: 9953280 After SpriteBatch Dispose(): 9953280

ADF page security - the untold password rule

- by ankuchak

I'm kinda new to Oracle ADF. So, in this blog post I'm going to share something with you that I faced (and recovered from) recently. Initially I thought if I should at all put a blog post on this, because it's totally simple. Still, simplicity is a relative term. So without wasting further time, let's kick off. I was exploring the ADF security aspect to secure a page through html basic authentication. The idea is very simple and the credential store etc. come into picture. But I was not able to run a successful test of this phenomenally simple thing even after trying for over 30 minutes. This is what I did. I created a simple jsf page and put a panel in it. And I put a simple el to show the current user name. Next I created a user that I should test with. I named the password as myuser, just to keep it simple. Then I created an enterprise role and mapped the user that I just created. Then I created an application role and mapped the enterprise role to it. Then I mapped the resource, the simple jsf page in this case, to this application role. This way, only users with the given application role can only access this page (as if you didn't know this duh!). Of course, I had to create the page definition for the page before I could map it to an application role. What else! done! Then I hit the run menu item and it all went well... Until... I got this message. I put the correct credentials repeatedly 2-3 times. Still I got the same error. Why? I didn't get any error message during the deployment. nope. Then, as I said before, I spent over 30 minutes trying different things out, things like mapping only the user(not the role) to the page, changing the context root etc. Nothing worked! Then of course, I bothered to look at the logs and found this. See the first red line. That says it all. So the problem was with that password. The password must have at least one special character and one digit in it. I think I was misled by the missing password hint/rule and the fact that the deployment didn't fail even if the user was not created properly. Well, yes, I agree that I was fool enough not to look at the logs. Later I changed the password to something like myuser123# . And it worked. I hope it helped.

Play in NetBeans IDE (Part 2)

- by Geertjan

Peter Hilton was one of many nice people I met for the first time during the last few days constituting JAX London. He did a session today on the Play framework which, if I understand it correctly, is an HTML5 framework. It doesn't use web.xml, Java EE, etc. It uses Scala internally, as well as in its templating language. Support for Play would, I guess, based on the little I know about it right now, consist of extending the HTML5 application project, which is new in NetBeans IDE 7.3. The workflow I imagine goes as follows. You'd create a new HTML5 application project, at which point you can choose a variety of frameworks and templates (Coffee Script, Angular, etc), which comes out of the box with the HTML5 support (i.e., Project Easel) in NetBeans IDE 7.3. Then, once the project is created, you'll right-click it and go to the Project Properties dialog, where you'll be able to enable Play support: At this stage, i.e., when you've checked the checkbox above and then clicked OK, all the necessary Play files will be added to your project, e.g., the routes file and the application.conf, for example. And then you have a Play application. Creating support in this way entails nothing more than creating a module that looks like this, i.e., with one Java class, where even the layer.xml file below is superfluous: All the code in the PlayEnablerPlanel.java that you see above is as follows: import java.awt.BorderLayout; import javax.swing.JCheckBox; import javax.swing.JComponent; import javax.swing.JPanel; import org.netbeans.spi.project.ui.support.ProjectCustomizer; import org.netbeans.spi.project.ui.support.ProjectCustomizer.Category; import org.openide.util.Lookup; public class PlayEnablerPanel implements ProjectCustomizer.CompositeCategoryProvider { @ProjectCustomizer.CompositeCategoryProvider.Registration( projectType = "org.netbeans.modules.web.clientproject", position = 1000) public static PlayEnablerPanel enablePlay() { return new PlayEnablerPanel(); } @Override public Category createCategory(Lookup lkp) { return ProjectCustomizer.Category.create("Play Framework", "Configure Play", null); } @Override public JComponent createComponent(Category ctgr, Lookup lkp) { JPanel playPanel = new JPanel(new BorderLayout()); playPanel.add(new JCheckBox("Enable Play"), BorderLayout.NORTH); return playPanel; } } Looking forward to having a beer with Peter soon (he lives not far away, in Rotterdam) to discuss this! Also read Part 1 of this series, which I wrote some time ago, and which has other ideas and considerations.

I am getting a 400 Bad Request error when using Nginx and PHP-FPM, why?

- by Bob

I am trying to run a website (that requires PHP - it technically doesn't require MySQL at this time, but it may sometime in the near future as I continue developing it, so I went ahead and installed that as well) using nginx 1.2.4 and PHP-FPM 5.3.3 on Ubuntu 12.04.1 LTS. As far as I know, I haven't done anything wrong, but clearly something is not quite right - I seem to be getting a 400 Bad Request error whenever I try to browse to my website. I've been mostly following one guide, and I've done more or less everything it recommends, except for not setting up PHP-FPM to use a Unix Socket and I used service as opposed to /etc/init.d/ when starting/stopping nginx, PHP, and MySQL. Anyways, here are my relevant configuration files (I have only censored personal/sensitive details, like my domain name - which contains my real name): /etc/nginx/nginx.conf user www-data; worker_processes 4; pid /var/run/nginx.pid; events { worker_connections 768; # multi_accept on; } http { ## # Basic Settings ## sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 15; types_hash_max_size 2048; # server_tokens off; # server_names_hash_bucket_size 64; # server_name_in_redirect off; include /etc/nginx/mime.types; default_type application/octet-stream; ## # Logging Settings ## access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; ## # Gzip Settings ## gzip on; gzip_disable "msie6"; # gzip_vary on; # gzip_proxied any; # gzip_comp_level 6; # gzip_buffers 16 8k; # gzip_http_version 1.1; # gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript; ## # nginx-naxsi config ## # Uncomment it if you installed nginx-naxsi ## #include /etc/nginx/naxsi_core.rules; ## # nginx-passenger config ## # Uncomment it if you installed nginx-passenger ## #passenger_root /usr; #passenger_ruby /usr/bin/ruby; ## # Virtual Host Configs ## include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; } /etc/nginx/sites-enabled/subdomain.mydomain.net server { listen 80; # listen for IPv4 listen [::]:80; # listen for IPv6 server_name www.subdomain.mydomain.net subdomain.mydomain.net; access_log /srv/www/subdomain.mydomain.net/logs/access.log; error_log /srv/www/subdomain.mydomain.net/logs/error.log; location / { root /srv/www/subdomain.mydomain.net/public; index index.php; } location ~ \.php$ { try_files $uri =400; include fastcgi_params; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /srv/www/subdomain.mydomain.net/public$fastcgi_script_name; } } All the directories listed in the configuration files above are correct on my server (to the extent of my knowledge). I have not included /etc/php5/fpm/pool.d/www.conf or /etc/php5/fpm/php.ini in this post as they're rather long, but I have posted them on Pastebin: http://pastebin.com/ensErJD8 and http://pastebin.com/T23dt7vM, respectively. Although, the only thing I've changed in either of the two files was in php.ini, where I set expose_php to off so as to hide the .php file extension from users. What can I do to resolve my issue? Please let me know if I need to supply any additional details.

Deadlock Analysis in NetBeans 8

- by Geertjan

Lock contention profiling is very important in multi-core environments. Lock contention occurs when a thread tries to acquire a lock while another thread is holding it, forcing it to wait. Lock contentions result in deadlocks. Multi-core environments have even more threads to deal with, causing an increased likelihood of lock contentions. In NetBeans 8, the NetBeans Profiler has new support for displaying detailed information about lock contention, i.e., the relationship between the threads that are locked. After all, whenever there's a deadlock, in any aspect of interaction, e.g., a political deadlock, it helps to be able to point to the responsible party or, at least, the order in which events happened resulting in the deadlock. As an example, let's take the handy Deadlock sample code from the Java Tutorial and look at the tools in NetBeans IDE for identifying and analyzing the code. The description of the deadlock is nice: Alphonse and Gaston are friends, and great believers in courtesy. A strict rule of courtesy is that when you bow to a friend, you must remain bowed until your friend has a chance to return the bow. Unfortunately, this rule does not account for the possibility that two friends might bow to each other at the same time. To help identify who bowed first or, at least, the order in which bowing took place, right-click the file and choose "Profile File". In the Profile Task Manager, make the choices below: When you have clicked Run, the Threads window shows the two threads are blocked, i.e., the red "Monitor" lines tell you that the related threads are blocked while trying to enter a synchronized method or block: But which thread is holding the lock? Which one is blocked by the other? The above visualization does not answer these questions. New in NetBeans 8 is that you can analyze the deadlock in the new Lock Contention window to determine which of the threads is responsible for the lock: Here is the code that simulates the lock, very slightly tweaked at the end, where I use "setName" on the threads, so that it's even easier to analyze the threads in the relevant NetBeans tools. Also, I converted the anonymous inner Runnables to lambda expressions. package org.demo; public class Deadlock { static class Friend { private final String name; public Friend(String name) { this.name = name; } public String getName() { return this.name; } public synchronized void bow(Friend bower) { System.out.format("%s: %s" + " has bowed to me!%n", this.name, bower.getName()); bower.bowBack(this); } public synchronized void bowBack(Friend bower) { System.out.format("%s: %s" + " has bowed back to me!%n", this.name, bower.getName()); } } public static void main(String[] args) { final Friend alphonse = new Friend("Alphonse"); final Friend gaston = new Friend("Gaston"); Thread t1 = new Thread(() -> { alphonse.bow(gaston); }); t1.setName("Alphonse bows to Gaston"); t1.start(); Thread t2 = new Thread(() -> { gaston.bow(alphonse); }); t2.setName("Gaston bows to Alphonse"); t2.start(); } } In the above code, it's extremely likely that both threads will block when they attempt to invoke bowBack. Neither block will ever end, because each thread is waiting for the other to exit bow. Note: As you can see, it really helps to use "Thread.setName", everywhere, wherever you're creating a Thread in your code, since the tools in the IDE become a lot more meaningful when you've defined the name of the thread because otherwise the Profiler will be forced to use thread names like "thread-5" and "thread-6", i.e., based on the order of the threads, which is kind of meaningless. (Normally, except in a simple demo scenario like the above, you're not starting the threads in the same class, so you have no idea at all what "thread-5" and "thread-6" mean because you don't know the order in which the threads were started.) Slightly more compact: Thread t1 = new Thread(() -> { alphonse.bow(gaston); },"Alphonse bows to Gaston"); t1.start(); Thread t2 = new Thread(() -> { gaston.bow(alphonse); },"Gaston bows to Alphonse"); t2.start();
