• Oracle Ebusiness Suite 12.1.3 Oracle VM templates

  - by wcoekaer

  Steven Chan just published a great blog entry that talks about the release of a new set of Oracle VM templates. Oracle Ebusiness Suite 12.1.3. You can find the blog post here. Templates are available for: E-Business Suite 12.1.3 Vision (64-bit) E-Business Suite 12.1.3 Production (32-bit) E-Business Suite 12.x Sparse Middle Tiers (32-bit and 64-bit) Thanks Steven! Why does this stuff matter? Well, in general, virtualization (or cloud) solutions provide an easy way to create Virtual Machines. Whether it's through a "cloud api" or just a virtualization API. But all you end up with, in the end, is still just a Virtual Machine... Maybe with an OS pre-installed/pre-configured. So you have flexibility of moving VMs around and providing a VM but what about the actual applications (anything more than a very basic app)? The application administrator then still has to go and install and configure the OS for that application and install the application and its patches and basic configuration so that the application user then can go in. Building gold images for complex software stacks that are not owned by the users/admins is always very difficult. With our templates, we provide a number of things : Oracle Linux pre-installed and pre-configured with the minimum required packages for that application to run. (so it's secure) Oracle Linux can be distributed and used for free or with a support subscription. There is no trial license, there is no registration key, no alpha version or community version versus enterprise version. You get what we provide in our engineered systems, what we provide support for, without change. Supported out of the box. No virtual Trial appliances, no prototypes, no POC. What you download is production ready without change. The applications are installed by the developers of the application. The database team builds database templates, the applications engineering team builds applications templates. The first boot/configuration scripts ask for the basic information such as hostname, ip address, user passwords and then go off and set everything up correctly. All tested together - application - operating system - hypervisor. not 3 (or more) products from 3(or more) different companies.

• TechEd 2010 Day Three: The Database Designer (Isn't)

  - by BuckWoody

  Yesterday at TechEd 2010 here in New Orleans I worked the front-booth, answering general SQL Server questions for the masses. I was actually a little surprised to find most of the questions I got were from folks that wanted to know more about Stream Insight and Master Data Services. In past conferences I've been asked a lot of "free consulting" questions, about problems folks have had from older products. I don't mind that a bit - in fact, I'm always happy to help in any way I can. But this time people are really interested in the new features in the product, and I like that they are thinking ahead, not just having to solve problems in production. My presentation was on "Database Design in an Hour". We had the usual fun, and SideShow Bob made an appearance - I kid you not. The guy in the back of the room looked just like Sideshow Bob, so I quickly held a "bes thair" contest, and he won. Duing the presentation, I explain the tools you can use to design databases. I also explain that the "Database Designer" tool in SQL Server Management Studio (SSMS) isn't truly a desinger - it uses non-standard notation, doesn't have a meta-data dictionary, and worst of all, it works at the physical level. In other words, whatever you do in SSMS will automatically change the field/table/relationship structures in the database. We fixed this in SSMS 2008 and higher by adding an option to block that, but the tool is not a good design function nonetheless. To be fair, no one I know of at Microsoft recommends that it is - but I was shocked to hear so many developers in the room defending it as a good tool. I think the main issue for someone who doesn't have to work with Relational Systems a great deal is that it can be difficult to figure out Foreign Keys. The syntax makes them look "backwards", so it's just easier to grab a field and place it on the table you want to point to. There are options. You can download a couple of free tools (CA has a community edition of ER-WIN, Quest has one, and Embarcadero also has one) and if you design more than one or two databases a year, it may be worth buying a true design tool. For years I used Visio, but we changed it so that it doesn't forward-engineer (create the DDL) any more, so it isn't a true design tool either. So investigate those free and not-so-free tools. You'll find they help you in your job - but stay away from the Database Designer in SSMS. Or I'll send Sideshow Bob over there to straighten you out.

• Executing server validators first before OnClientClick Javascript confirm/alert

  - by kaushalparik27

  I got to answer a simple question over community forums. Consider this: Suppose you are developing a webpage with few input controls and a submit button. You have placed some server validator controls like RequiredFieldValidator to validate the inputs entered by the user. Once user fill-in all the details and try to submit the page via button click you want to alert/confirm the submission like "Are you sure to modify above details?". You will consider to use javascript on click of the button.Everything seems simple and you are almost done. BUT, when you run the page; you will see that Javascript alert/confirm box is executing first before server validators try to validate the input controls! Well, this is expected behaviour. BUT, this is not you want. Then? The simple answer is: Call Page_ClientValidate() in javascript where you are alerting the submission. Below is the javascript example:    <script type="text/javascript" language="javascript">        function ValidateAllValidationGroups() {            if (Page_ClientValidate()) {                return confirm("Are you sure to modify above details?");            }        }    </script>Page_ClientValidate() function tests for all server validators and return bool value depends on whether the page meets defined validation criteria or not. In above example, confirm alert will only popup up if Page_ClientValidate() returns true (if all validations satisfy). You can also specify ValidationGroup inside this function as Page_ClientValidate('ValidationGroup1') to only validate a specific group of validation in your page.        function ValidateSpecificValidationGroup() {            if (Page_ClientValidate('ValidationGroup1')) {                return confirm("Are you sure to modify above details?");            }        }I have attached a sample example with this post here demonstrating both above cases. Hope it helps./.

• To Serve Man?

  - by Dave Convery

  Since the announcement of Windows 8 and its 'Metro' interface, the .NET community has wondered if the skills they've spent so long developing might be swept aside,in favour of HTML5 and JavaScript. Mercifully, that only seems to be true of SilverLight (as Simon Cooper points out), but it did leave me thinking how easy it is to impose a technology upon people without directly serving their needs. Case in point: QR codes. Once, probably, benign in purpose, they seem to have become a marketer's tool for determining when someone has engaged with an advert in the real world, with the same certainty as is possible online. Nobody really wants to use QR codes - it's far too much hassle. But advertisers want that data - they want to know that someone actually read their billboard / poster / cereal box, and so this flawed technology is suddenly everywhere, providing little to no value to the people who are actually meant to use it. What about 3D cinema? Profits from the film industry have been steadily increasing throughout the period that digital piracy and mass sharing has been possible, yet the industry cinema chains have forced 3D films upon a broadly uninterested audience, as a way of providing more purpose to going to a cinema, rather than watching it at home. Despite advances in digital projection, 3D cinema is scarcely more immersive to us than were William Castle's hoary old tricks of skeletons on wires and buzzing chairs were to our grandparents. iTunes - originally just a piece of software that catalogued and ripped music for you, but which is now multi-purpose bloatware; a massive, system-hogging behemoth. If it was being built for the people that used it, it would have been split into three or more separate pieces of software long ago. But as bloatware, it serves Apple primarily rather than us, stuffed with Music, Video, Various stores and phone / iPad management all bolted into one. Why? It's because, that way, you're more likely to bump into something you want to buy. You can't even buy a new laptop without finding that a significant chunk of your hard drive has been sold to 'select partners' - advertisers, suppliers of virus-busting software, and endless bloatware-flogging pop-ups that make using a new laptop without reformatting the hard drive like stepping back in time. The product you want is not the one you paid for. This is without even looking at services like Facebook and Klout, who provide a notional service with the intention of slurping up as much data about you as possible (in Klout's case, whether you create an account with them or not). What technologies do you find annoying or intrusive, and who benefits from keeping them around?

• My Reference for Amy Lewis

  - by Denise McInerney

  The 2013 election campaign for the PASS Board of Directors is underway. There are seven qualified candidates running this year. They all offer a wealth of experience volunteering for PASS and the SQL Server community. One of these candidates, Amy Lewis, asked me to write a reference for her to include on her candidate application. I have a lot of experience working with Amy and was pleased to provide this reference: I enthusiastically support Amy Lewis as a candidate for the PASS Board of Directors. I have known and worked with Amy in various PASS' volunteer capacities for years, starting when we were both leaders of SIGs (the precursors to the Virtual Chapters.) In that time I have seen Amy grow as a leader, taking on increasing responsibility and developing her leadership skills in the process. From the Program Committee to the BI Virtual Chapter to her local user group's SQL Saturday Amy has demonstrated a capacity to organize and lead volunteers. A successful leader delivers results, and does so in a way that encourages and empowers the people she is working with; Amy embodies this leadership style. As Director for Virtual Chapters I have most recently worked with Amy in her capacity of DW/BI VC Leader. This VC is one of our largest and most active, and Amy's leadership is a key contribution to that success. I was pleased to see that Amy was also thinking about succession and prepared other volunteers to take over the chapter leadership. Amy has shown an understanding of PASS' strategic goals and has focused her volunteer efforts to help us reach those goals. For the past couple of years we have been trying to expand PASS reach and relevance to SQL communities around the world. The VCs are a key vehicle for this expansion. Amy embraced this idea and organized the VC to engage volunteers in Europe & Australia and provide content that could reach SQL professionals in those regions. A second key strategy for PASS is expanding into the data analytics space. Again Amy rose to the occasion helping to shape the program for our first Business Analytics Conference and leveraging the BI VC to promote the event. By all measures I think Amy is prepared to serve on the Board and contribute in a positive way.

• New hidden parameters in Oracle 11.2

  - by Mike Dietrich

  We really welcome every external review of our slides. And also recommendations from customers visiting our workshops. So it happened to me more than a week ago that Marco Patzwahl, the owner of MuniqSoft GmbH, had a very lengthy train ride in Germany (as the engine drivers go on strike this week it could have become even worse) and nothing better to do then reviewing our slide set. And he had plenty of recommendations. Besides that he pointed us to something at least I was not aware of and added it to the slides: In patch set 11.2.0.2 a new behaviour for datafile write errors has been implemented. With this release ANY write error to a datafile will cause the instance to abort. Before 11.2.0.2 those errors usually led to an offline datafile if the database operates in archivelog mode (your production database do, don’t they?!) and the datafile does not belong to the SYSTEM tablespace. Internal discussion found this behaviour not up-to-date and alligned with RAC systems and modern storages. Therefore it has been changed and a new underscore parameter got introduced. _DATAFILE_WRITE_ERRORS_CRASH_INSTANCE=TRUE This is the default setting´and the new behaviour beginning with Oracle 11.2.0.2 If you would like to revert to the pre-11.2.0.2 behaviour you’ll have to set in your init.ora/spfile this parameter to false. But keep in mind that there’s a reason why this has been changed. You’ll find more info in MOS Note: 7691270.8 and this topic in the current version of the slides on slide 255. Thanks to Marco for the review!!   And then I received an email from Kurt Van Meerbeeck today. Kurt is pretty well known in the Oracle community. And he’s the owner of jDUL/DUDE, a database unloading tool which bypasses the Oracle database engine and access data direclty from the blocks. Kurt visited the upgrade workshop two weeks ago in Belgium and did highlight to me that since Oracle 11.2.0.1 even though you haven’t set neither SGA_TARGET nor MEMORY_TARGET the database might still do resize operations. Reason why this behaviour has been changed: Prevention of ORA-4031 errors. But on databases with extremly high loads this can cause trouble. Further information can be found in MOS Note:1269139.1 . And the parameter set to TRUE by default is called _MEMORY_IMM_MODE_WITHOUT_AUTOSGA=TRUE This can be found now in the slide set as well on slide number 240. And thanks to Kurt for this information!!

• User connection management in Reporting Services configuration

  - by Testas

  IT professionals will use Reporting Services Configuration Manager to perform post installation tasks for SQL Server Reporting Services. Introduced in SQL Server 2005, Reporting Services Configuration Manager provides an intuitive interface to perform tasks including specifying the report server database, report manager url, and indeed one of the first post installation tasks that should be performed is backing up the encryption keys that are used to protect the sensitive information within the rdl files.  Many of the options that are selected within Reporting Services Configuration Manager are written to a number of configuration files including the rsreportserver.config file located in C:\Program Files\Microsoft SQL Server\Report Server InstanceName\Reporting Services\ReportServer folder.When opening this file you will notice that there are more configuration settings within the rsreportserver.config file than is available through the Reporting Services Configuration Manager Interface. As a result there are additional configuration options that can be defined within this file.  A customer was having a problem performing stress tests against a new Report Server that would be going live for an enterprise reporting system. One aspect of the stress test was to fire 50 connections from a single user account. When performing the stress test an error described that the maximum active request had been exceeded. Within the rsreportserver.config, there is a key that is added to the file:  <Add Key=”MaxActiveReqForOneUser” Value=”20”/>  Changing the value from 20 to 50 accommodated the needs of the stress test, however, a wider question should be asked pertaining to this setting when implementing Reporting Services to a production environment. Within an intranet environment, the default setting is appropriate when network bandwidth is high, users are known and demand for reports is particularly high from a group of users.  However, when deploying a Reporting Server solution to an extranet, or the internet, you may want to consider reducing this setting to reduce to scope of connections that can be acquired by a single user and placing unnecessary pressure on the report server. I do hope that Reporting Services Configuration Manager evolves to include an advanced page that includes an intuitive interface to change configuration settings such as the MaxActiveReqForOneUser, and also configure rendering and data extensions and define secure connection levels to the report server. All these options can be configured within the rsreportserver.config file, and these are setting that customers would like to see in Reporting Services Configuration Manager in the future.   If you think that the SQL community would benefit from this addition, you can vote on it at Microsoft Connect  https://connect.microsoft.com/SQLServer/feedback/details/565575/extending-reporting-services-configuration-manager-rscm

• Using ext4 in VMware machine

  First of all, using a journaling filesystems like NTFS, ext4, XFS, or JFS (not to name all of them) is a very good idea and nowadays unthinkable not to do. Linux offers a good variety of different option as journaling filesystem for your system. Since years I am using SGI's XFS and I am pretty confident with stability, performance and liability of the system. In earlier years I had to struggle with incompatibilities between XFS and the boot loader. Using an ext2 formatted /boot solved this issue. But, wow, that is ages ago! Lately, I had to setup a fresh Lucid Lynx (Ubuntu 10.04 LTS) system for a change of our internal groupware / messaging system. Therefore, I fired up a new virtual machine with almost standard configuration in VMware Server and run through our network-based PXE boot and installation procedure. At a certain step in this process, Ubuntu asks you about the partitioning of your hard drive(s). Honestly, I have to say that only out of curiousity I sticked to the "default" suggestion and gave my faith and trust into the Ubuntu installation routine... Resulting to have an ext4 based root mount point ( / ). The rest of the installation went on without further concerns or worries. Note:I really can't remember why I chose to go away from my favourite... Well, it should turn out to be the wrong decision after all. Ok, let's continue the story about ext4 in a VMware based virtual machine. After some hours installing additional packages and configuring the new system using LDAP for general authentication and login, I had an "out-of-the-box" usable enterprise messaging system based on Zarafa 6.40 Community Edition inclusive proper SSL-based Webaccess interface and Z-Push extension for ActiveSync with my Nokia mobile. Straightforward and pretty nice for the time spent on the setup. Having priority on other tasks I let the system just running and didn't pay any further attention at all. Until I run into an upgrade of "Mail for Exchange" on Symbian OS. My mobile did not bother me at all with the upgrade and everything went smooth, but trying to re-establish the ActiveSync connection to the Zarafa messaging system resulted in a frustating situation. So, I shifted my focus back to the Linux system and I was amazed to figure out that the root had been remounted readonly due to hard drive failures or at least ext4 reported errors. Firing up Google only confirmed my concerns and it seems that using ext4 for VMware based virtual machines does not look like a stable and reliable candidate to me. You might consider reading those external resources: ext4 fs corruption under VMWare Server 2.01Bug #389555 - ext4 filesystem corruption Well, I learned my lesson and ext{2|3|4} based filesystems are not going to be used on any of my Linux systems or customer installations in the future. Addendum: I did not try this setup in other virtualization environments like VirtualBox, qemu, kvm, Xen, etc.

• Basic web architecture : Perl -> PHP

  - by Sunny Jim

  This is an architecture question. If there is a better forum, please redirect me. Apologies in advance. Essentially every website is built around a relational database, right? When a user uploads form data, that data is stored in a table. The problem is that the table structure(s) need to be modified whenever the website form is modified. Although I understand that modern web frameworks work around this problem by automatically building forms based on the table structure. For the last 20 years, I have been building websites using Perl. When I first encountered this problem, the easiest solution was to save serialized Perl objects as data BLOBS. After XML's introduction, this solution worked even better because XML is so effective for representing arbitrary data. This approach is consistent with the original Perl principles of Hubris, Laziness, and Impatience and I'm pretty committed to it. Obviously, the biggest drawback is that this solution locks me into the Perl interpreter. So instead, I've just completed a prototype of a universal RDB table. The prototype is written in Perl but porting it to PHP will be a good chance to develop those skills. The principal is based on the XML::Dumper module, which converts arbitrary Perl data structures into uniform XML. With my approach, each XML node is stored as a table record. I underestimated this undertaking and rolled something up myself. But the effort allows me to discuss the basic design instead of implementation details. As mentioned, I'm pretty committed to this approach of using flexible data structures. It's been successfully deployed on many websites, large, and complex. But are there any drawbacks I've overlooked? I rolled my own. Are other people taking a similar approach to their data? What kinds of solutions are available? I have not abandoned my dream of eventually contributing something useful to the worldwide community. In order to proceed, the next step would be peer review. How does one pursue that effort? Thanks! -Jim

• Bay Area Coherence Special Interest Group Next Meeting July 21, 2011

  - by csoto

  Date: Thursday, July 21, 2011 Time: 4:30pm - 8:15pm ET (note that Parking at 475 Sansome Closes at 8:30pm) Where: Oracle Office, 475 Sansome Street, San Francisco, CA Google Map We will be providing snacks and beverages. Register! - Registration is required for building security. Presentation Line Up:? 5:10pm - Batch Processing Using Coherence in Oracle Group Policy Administration - Paul Cleary, Oracle Oracle Insurance Policy Administration (OIPA) is a flexible, rules-based policy administration solution that provides full record keeping for all policy lifecycle transactions. One component of OIPA is Cycle processing, which is the batch processing of pending insurance transactions. This presentation introduces OIPA and Cycle processing, describing the unique challenges of processing a high volume of transactions within strict time windows. It then reviews how OIPA uses Oracle Coherence and the Processing Pattern to meet these challenges, describing implementation specifics that highlight the simplicity and robustness of the Processing Pattern. 6:10pm - Secure, Optimize, and Load Balance Coherence with F5 - Chris Akker, F5 F5 Networks, Inc., the global leader in Application Delivery Networking, helps the world’s largest enterprises and service providers realize the full value of virtualization, cloud computing, and on-demand IT. Recently, F5 and Oracle partnered to deliver a novel solution that integrates Oracle Coherence 3.7 with F5 BIG-IP Local Traffic Manager (LTM). This session will introduce F5 and how you can leverage BIG-IP LTM to secure, optimize, and load balance application traffic generated from Coherence*Extend clients across any number of servers in a cluster and to hardware-accelerate CPU-intensive SSL encryption. 7:10pm - Using Oracle Coherence to Enable Database Partitioning and DC Level Fault Tolerance - Alexei Ragozin, Independent Consultant and Brian Oliver, Oracle Partitioning is a very powerful technique for scaling database centric applications. One tricky part of partitioned architecture is routing of requests to the right database. The routing layer (routing table) should know the right database instance for each attribute which may be used for routing (e.g. account id, login, email, etc): it should be fast, it should fault tolerant and it should scale. All the above makes Oracle Coherence a natural choice for implementing such routing tables in partitioned architectures. This presentation will cover synchronization of the grid with multiple databases, conflict resolution, cross cluster replication and other aspects related to implementing robust partitioned architecture.

• TypeScript first impressions

  - by Bertrand Le Roy

  Anders published a video of his new project today, which aims at creating a superset of JavaScript, that compiles down to regular current JavaScript. Anders is a tremendously clever guy, and it always shows in his work. There is much to like in the enterprise (good code completion, refactoring and adoption of the module pattern instead of namespaces to name three), but a few things made me rise an eyebrow. First, there is no mention of CoffeeScript or Dart, but he does talk briefly about Script# and GWT. This is probably because the target audience seems to be the same as the audience for the latter two, i.e. developers who are more comfortable with statically-typed languages such as C# and Java than dynamic languages such as JavaScript. I don’t think he’s aiming at JavaScript developers. Classes and interfaces, although well executed, are not especially appealing. Second, as any code generation tool (and this is true of CoffeeScript as well), you’d better like the generated code. I didn’t, unfortunately. The code that I saw is not the code I would have written. What’s more, I didn’t always find the TypeScript code especially more expressive than what it gets compiled to. I also have a few questions. Is it possible to duck-type interfaces? For example, if I have an IPoint2D interface with x and y coordinates, can I pass any object that has x and y into a function that expects IPoint2D or do I need to necessarily create a class that implements that interface, and new up an instance that explicitly declares its contract? The appeal of dynamic languages is the ability to make objects as you go. This needs to be kept intact. More technical: why are generated variables and functions prefixed with _ rather than the $ that the EcmaScript spec recommends for machine-generated variables? In conclusion, while this is a good contribution to the set of ideas around JavaScript evolution, I don’t expect a lot of adoption outside of the devoted Microsoft developers, but maybe some influence on the language itself. But I’m often wrong. I would certainly not use it because I disagree with the central motivation for doing this: Anders explicitly says he built this because “writing application-scale JavaScript is hard”. I would restate that “writing application-scale JavaScript is hard for people who are used to statically-typed languages”. The community has built a set of good practices over the last few years that do scale quite well, and many people are successfully developing and maintaining impressive applications directly in JavaScript. You can play with TypeScript here: http://www.typescriptlang.org

• Java EE 7 turns one today!

  - by delabassee

  "Tell me and I forget. Teach me and I remember. Involve me and I learn." (Benjamin Franklin) Today marks the first year anniversary of Java EE 7. The JSR 342 specification was finalised on May 28, 2013 with the official launch taking place on June 12, 2013 (original press release). As of today, there are already 3 Java EE 7 compatible Application Servers, coming from different 'vendors' (Oracle, TmaxSoft and Red Hat). Two of those Java EE 7 Application Servers are free and open source. We expect the list of Java EE 7 compatible Application Servers to grow over the coming months. Source: RebelLabs - 'Java Tools and Technologies Landscape for 2014' According to a recent independent survey, one third of the Java EE users who participated in that survey is already using Java EE 7. This is a good sign but it also means that a lot of people are not yet on Java EE 7. So if you haven't yet embarked on Java EE 7, now is really the time to do so! There are various ways to learn Java EE 7, in no particular order ... Continue to read The Aquarium. Through this blog, we are relaying Java EE news but we are also doing our best to highlight relevant technical contents such as articles, community tutorials, etc. Watch the GlassFish YouTube channel. Amongst others, it contains the different videos of the Java EE 7 launch, those videos will give you good technical update on Java EE and its different components specifications (JMS 2.0, JAX-RS 2.0, EJB 3.2, etc.) Take a formal training. Oracle University is starting to roll-out Java EE 7 trainings like the 'Java EE 7: New Features' class.  Attend conferences and JUGs sessions. On that note, we have spent a lot of time to create a strong JavaOne 'Server-Side Java' track. It's still possible to benefit from the early bird JavaOne pricing but don't wait too much! Read books. There are more than 25 (!) books related to Java EE 7 or to one of the Java EE 7 component specification.  There are many more ways to learn Java EE but if I have to suggest one and only one way, I would recommend the Java EE 7 Tutorial. It's exhaustive and clear, it's free and it continues to evolve. And finally as the introductory quote suggest, participation is key to learning. Participate in JUGs,  participate in Adopt-a-JSR, get involved in the different open source communities evolving around Java EE, participate in the JCP... in one word, participate!

• WPF Control Toolkits Comparison for LOB Apps

  In preparation for a new WPF project Ive been researching options for WPF Control toolkits.  While we want a lot of the benefits of WPF, the application is a fairly typical line of business application (LOB).  So were not focused on things like media and animations, but instead a simple, solid, intuitive, and modern user interface that allows for well architected separation of business logic and presentation layers. While WPF is mature, it hasnt lived the long life that Winforms has yet, so there is still a lot of room for third party and community control toolkits to fill the gaps between the controls that ship with the Framework.  There are two such gaps I was concerned about.  As this is an LOB app, we have needs for presenting lots of data and not surprisingly much of it is in grid format with the need for high performance, grouping, inline editing, aggregation, printing and exporting and things that weve been doing with LOB apps for a long time.  In addition we want a dashboard style for the UI in which the user can rearrange and shrink and grow tiles that house the content and functionality.  From a cost perspective, building these types of well performing controls from scratch doesnt make sense.  So I evaluated what you get from the .NET Framework along with a few different options for control toolkits.  I tried to be fairly thorough, but know that this isnt a detailed benchmarking comparison or intense evaluation.  Its just meant to be a feature set comparison to be used when thinking about building an LOB app in WPF.  I tried to list important feature differences and notes based on my experience with the trial versions and what I found in documentation and reference materials and samples.  Ive also listed the importance of the controls based on how I think they are needed in LOB apps.  There are several toolkits available, but given I dont have unlimited time, I picked just a few.  Maybe Ill add on more later.  The toolkits I compared are: Teleriks RadControls for WPF since I had heard some good things about Telerik Infragistics NetAdvantage WPF since both I and the customer have some experience with the vendors tools WPF Toolkit on codeplex since many of my colleagues have used it Blacklight codeplex project which had WPF support for the Tile View control  (with Release 4.3 WPF is not going to be supported in favor of focusing only on SilverLight controls, so I dropped that from the comparison) Click Here to Download the WPF Control Toolkits Comparison Hopefully this helps someone out there.  Feel free to post a comment on your experiences or if you think something I listed is incorrect or missing.  Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• 24HOP gets off to a good start

  - by Rob Farley

  Session 11 is on as I write this – Ami Levin presenting about Primary Keys. It’s a good session. But actually, they’ve all been excellent so far, not just Ami’s. I’ve heard only good things about the content. So if you’re reading this and 24HOP is still on, then tune in and take part. If it’s finished, get yourself over to http://sqlpass.org/24hours and see if the sessions have been made available on-demand. Yes – you should be able to watch the sessions when you want to for a year. Watching live is best, because you can ask questions and have them answered during the session, but if there are ones you just couldn’t make, then watching them on-demand is a good option. Numbers have been “not bad”. At the moment it’s still the middle of the night for most Americans – about 6:30am in New York, and yet we’ve had well over a hundred at all the sessions so far, getting up to well over 300 for some sessions. And when I look through the list of names, I see a bunch of names that suggest we’re reaching people from all around the world. I’m seriously looking forward to seeing the stats about which countries have been represented in the audiences. There have been a few comments about the platform. Everyone seems to consider IBTalk an improvement on LiveMeeting, but the closed captioning has met a mixed reception. Some people are loving it, whereas other people are finding the translations leave quite a bit of space for improvement. If you have feedback on this, please feel free to drop me an email (my name with an underscore at hotmail.com, or with a dot at sqlpass.org should reach me just fine, or Twitter, etc). I don’t know how many of the sessions I’ll get to watch overnight – but I’m looking forward to seeing how things go as the day progresses. Big thanks to everyone who’s involved – the sponsors, PASS HQ team and the IBTalk folk who have stayed up overnight to facilitate, plus the moderators, the people doing the live captioning, and of course the speakers and attendees. I love how the SQL Community gets behind things like this. Earlier, the Adelaide SQL Server User Group gathered and watched Denny Lee’s session on BigData, and everyone in the group agreed that it worked really well. I took a picture of our cinema room, although you could only see a small section of the audience. @rob_farley

• Book review: Peopleware: Productive Projects and Teams

  - by DigiMortal

     Peopleware by Tom DeMarco and Timothy Lister is golden classic book that can be considered as mandatory reading for software project managers, team leads, higher level management and board members of software companies. If you make decisions about people then you cannot miss this book. If you are already good on managing developers then this book can make you even better – you will learn new stuff about successful development teams for sure. Why peopleware? Peopleware gives you very good hints about how to build up working environment for project teams where people can really do their work. Book also covers team building topics that are also important reading. As software developer I found practically all points in this book to be accurate and valid. Many times I have found my self thinking about same things and Peopleware made me more confident about my opinions. Peopleware covers also time management and planning topics that help you do way better job on using developers time effectively by minimizing the amount of interruptions by phone calls, pointless meetings and i-want-to-know-what-are-you-doing-right-now questions by managers who doesn’t write code anyway. I think if you follow suggestions given by Peopleware your developers are very happy. I suggest you to also read another great book – Death March by Edward Yourdon. Death March describes you effectively what happens when good advices given by Peopleware are totally ignored or worse yet – people are treated exactly opposite way. I consider also Death March as golden classics and I strongly recommend you to read this book too.

• How do I configure sound with PulseAudio and Multiseat?

  - by Anthony

  In the spirit of full disclosure, i just posted this question to the ubuntu forums, but i figure more heads working on it couldn't hurt. I have a multi-seat setup working quite well. Hot plugging input devices works as expected and such. The only issue I am still not able to resolve is getting the audio for each seat. Here is a summary of my attempts at getting audio to work: Make ~/.pulse/default.pa dynamically configured based on which $DISPLAY the user logs in at. See this pastebin for the details. Load pulseaudio as a system-wide instance. Couldn't get this to work. None of the audio hardware was accessible to the users. Use udev rules to mark seats in ConsoleKit. Following udev guidelines found here: http://www.freedesktop.org/wiki/Software/systemd/multiseat I didn't think this would work, although it was "guaranteed" to work by someone in irc.freenode #pulseaudio None of those attempts yielded success, which is why I now turn to the community for help. It is quite possible that the suggested methods work and I just messed some aspect of it up, idk. This is the last piece of the puzzle which is needed before I can go and update the MultiseatX page to include instructions for Ubuntu 12.04. My understandings on the situation: Access to pulseaudio is restricted to the active session as marked by ConsoleKit (something about an ACL). CK can only mark one session as active at a time. This simple little fact of life leads me to believe that the solution should involve pulseaudio being run as a system-wide instance. Each user should connect to the pulse server and be limited to a subset of all the hardware. Maybe each user connects to the pulse server via localhost, idk. I do know that regardless of my attempts and their failed results, I was always able to use sudo aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav to play something to any of the hardware. I'm grasping at straws and am now down to the last few hairs i can pull out of my head. Please, help me figure this out so we can share the wealth. Any additional information needed will be provided at your request.

• Kicking off the ODI12c Blog Series

  - by Madhu Nair

  Normal 0 false false false EN-US ZH-TW X-NONE MicrosoftInternetExplorer4 It is always exciting to talk about a new release, especially one as significant as the newly released Oracle Data Integrator 12c (ODI12c). Why? Because it is packed with features that addresses many requirements for the user community. If you missed sneak previews at this year's Oracle Open World sessions, do not despair. Because over the coming weeks the ODI12c team of developers and consultants will be sharing their perspective on key features, experiences and best practices for ODI12c right here through a series of blogs. Before diving into feature details in subsequent blogs it helps to understand the overall themes that went into developing ODI12c. Let the Productivity Flow: Let us face it. Designing for developer user experience is always top of mind to any enterprise software. ODI12c addresses this through the introduction of declarative flow based mappings (the topic of our next ODI blog by the way!!). Reusability has been addressed though the introduction of reusable mappings cutting down development times for repeated logics. An enhanced debugger makes life easy for complex granular debugging scenarios. Unique repository IDs now allow you to manage multiple repositories. Performance is Paramount: Another major area of focus for ODI12c is performance. Increased parallelism (like the multiple target table load feature), reduced session overheads and ability to customize loads plans through physical views all empower the user to tune run times for extreme performances. mapping showing multiple target load physical representation allowing users to choose execution options Integrating it all: This release is not just about ODI12c as a standalone product. Closer integration with Oracle GoldenGate now brings Change Data Capture (CDC) capabilities into ODI12c. Oracle Warehouse Builder (OWB) jobs can now be executed and monitored from within ODI12c. And ODI12c is fast becoming the de facto standard for Oracle Applications that need data integration in their solutions. The best example being the latest release of the Oracle BI Applications technology. Even as we bring you in-depth write-ups about the features there are some great previews and resources that are already out there. Like this super entry by beta partner Rittman Mead Consulting and this ODI12c Key Features White Paper. You can download ODI12c here (this post helps). The best though is the upcoming Executive Webcast featuring customers and executives who have seen and conceived the product. Don’t miss it!

• XAML RadControls Q1 2010 Official

  Q1 2010 release focuses on strengthening 3 main aspects of RadControls for Silverlight and RadControls for WPF: Ensuring first-class performance for all data-centric controls through various techniques, Enhancing and polishing RadControls themes Providing highly advanced, enterprise-level features, especially for the data visualization controls  We know that performance is crucial for line-of-business applications. Therefore, we always make sure that RadControls can help you achieve unmatched performance and this has always been our number one priority. RadControls achieve unbeatable performance through UI and Data Virtualization, Data Sampling and built-in Load On Demand features. Several of the major controls in the bundles have been enhanced with UI virtualization support Scheduler, CoverFlow and Book. As a part of Q1 2010 we also want to bring an unparalleled visual richness to your applications. To achieve that we have done a major rework of all our themes. We used a uniform templating approach across all controls, streamlined naming conventions for resources and delivered a much more consistent look of the controls along the way. RadControls for WPF bundle has been enriched with two new controls Map and Book.   Another new control has been included in the Q1 2010 release. However, it continues to be in a CTP stage. This is the Transition control. We decided that this is the better way to proceed as we will need some more input from our community on how exactly to develop this control further. Therefore, we will be regularly blogging on the development progress so that we can clearly indicate the direction, in which the control is evolving and gather your feedback on whether this is the best direction. Our Charting controls for Silverilght and WPF have been advanced with major new features such as Data Sampling, Zooming and Scrolling, Automatic SmartLables positioning, Sorting and Filtering and many more. The new built-in paging of the GridView control now allows you to page through your data, thus resulting in an event faster and more responsive grid that can easily handle enormously large datasets. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.
