  • Oracle Tutor: Installing Is Not Implementing or Why CIO's should care about End User Adoption

    - by emily.chorba(at)oracle.com
    Eighteen months ago I showed Tutor and UPK Productive Day One overview to a CIO friend of mine. He works in a manufacturing business which had been recently purchased by a global conglomerate. He had a major implementation coming up, but said that the corporate team would be coming in to handle the project. I asked about their end user training approach, but it was unclear to him at the time. We were in touch over the course of the implementation project. The major activities were data conversion, how-to workshops, General Ledger realignment, and report definition. The message was "Here's how we do it at corporate, and here's how you are going to do it." In short, it was an application software installation. The corporate team had experience and confidence and the effort through go-live was smooth. Some weeks after cutover, problems with customer orders began to surface. Orders could not be fulfilled in a timely fashion. The problem got worse, and the corporate emergency team was called in. After many days of analysis, the issue was tracked down and resolved, but by then there were weeks of backorders, and their customer base was impacted in a significant way. It took three months of constant handholding of customers by the sales force for good will to be reestablished, and this itself diminished a new product sales push. I learned of these results in a recent conversation with the CIO. I asked him what the solution to the problem was, and he replied that it was twofold. The first component was a lack of understanding by customer service reps about how a particular data item in order entry was to be filled in, resulting in discrepant order data. The second component was that product planners were using this data, along with data from other sources, to fill in a spreadsheet based on the abandoned system. This spreadsheet was the primary input for planning data. The result of these two inaccuracies was that key parts were not being ordered to effectively meet demand and the lead time for finished goods was pushed out by weeks. I reminded him about the Productive Day One approach, and it's focus on methodology and tools for end user training. A more collaborative solution workshop would have identified proper applications use in the new environment. Using UPK to document correct transaction entry would have provided effective guidelines to the CSRs for data entry. Using Oracle Tutor to document the manual tasks would have eliminated the use of an out of date spreadsheet. As we talked this over, he said, "I wish I knew when I started what I know now." Effective end user adoption is the most critical and most overlooked success factor in applications implementations. When the switch is thrown at go-live, employees need to know how to use the new systems to do their jobs. Their jobs are made up of manual steps and systems steps which must be performed in the right order for the implementing organization to operate smoothly. Use Tutor to document the manual policies and procedures, use UPK to document the systems tasks, and develop this documentation in conjunction with a solution workshop. This is the path to develop effective end user training material for a smooth implementation. Learn More For more information about Tutor, visit Oracle.com or the Tutor Blog.

  • Subterranean IL: Custom modifiers

    - by Simon Cooper
    In IL, volatile is an instruction prefix used to set a memory barrier at that instruction. However, in C#, volatile is applied to a field to indicate that all accesses on that field should be prefixed with volatile. As I mentioned in my previous post, this means that the field definition needs to store this information somehow, as such a field could be accessed from another assembly. However, IL does not have a concept of a 'volatile field'. How is this information stored? Attributes The standard way of solving this is to apply a VolatileAttribute or similar to the field; this extra metadata notifies the C# compiler that all loads and stores to that field should use the volatile prefix. However, there is a problem with this approach, namely, the .NET C++ compiler. C++ allows methods to be overloaded using properties, like volatile or const, on the parameters; this is perfectly legal C++: public ref class VolatileMethods { void Method(int *i) {} void Method(volatile int *i) {} } If volatile was specified using a custom attribute, then the VolatileMethods class wouldn't be compilable to IL, as there is nothing to differentiate the two methods from each other. This is where custom modifiers come in. Custom modifiers Custom modifiers are similar to custom attributes, but instead of being applied to an IL element separately to its declaration, they are embedded within the field or parameter's type signature itself. The VolatileMethods class would be compiled to the following IL: .class public VolatileMethods { .method public instance void Method(int32* i) {} .method public instance void Method( int32 modreq( [mscorlib]System.Runtime.CompilerServices.IsVolatile)* i) {} } The modreq([mscorlib]System.Runtime.CompilerServices.IsVolatile) is the custom modifier. This adds a TypeDef or TypeRef token to the signature of the field or parameter, and even though they are mostly ignored by the CLR when it's executing the program, this allows methods and fields to be overloaded in ways that wouldn't be allowed using attributes. Because the modifiers are part of the signature, they need to be fully specified when calling such a method in IL: call instance void Method( int32 modreq([mscorlib]System.Runtime.CompilerServices.IsVolatile)*) There are two ways of applying modifiers; modreq specifies required modifiers (like IsVolatile), and modopt specifies optional modifiers that can be ignored by compilers (like IsLong or IsConst). The type specified as the modifier argument are simple placeholders; if you have a look at the definitions of IsVolatile and IsLong they are completely empty. They exist solely to be referenced by a modifier. Custom modifiers are used extensively by the C++ compiler to specify concepts that aren't expressible in IL, but still need to be taken into account when calling method overloads. C++ and C# That's all very well and good, but how does this affect C#? Well, the C++ compiler uses modreq(IsVolatile) to specify volatility on both method parameters and fields, as it would be slightly odd to have the same concept represented using a modifier or attribute depending on what it was applied to. Once you've compiled your C++ project, it can then be referenced and used from C#, so the C# compiler has to recognise the modreq(IsVolatile) custom modifier applied to fields, and vice versa. So, even though you can't overload fields or parameters with volatile using C#, volatile needs to be expressed using a custom modifier rather than an attribute to guarentee correct interoperability and behaviour with any C++ dlls that happen to come along. Next up: a closer look at attributes, and how certain attributes compile in unexpected ways.

  • Adding Output Caching and Expire Header in IIS7 to improve performance

    - by Renso
    The problem: Images and other static files will not be cached unless you tell it to. In IIS7 it is remarkably easy to do this. Web pages are becoming increasingly complex with more scripts, style sheets, images, and Flash on them. A first-time visit to a page may require several HTTP requests to load all the components. By using Expires headers these components become cacheable, which avoids unnecessary HTTP requests on subsequent page views. Expires headers are most often associated with images, but they can and should be used on all page components including scripts, style sheets, and Flash. Every time a page is loaded, every image and other static content like JavaScript files and CSS files will be reloaded on every page request. If the content does not change frequently why not cache it and avoid the network traffic?! The solution: In IIS7 there are two ways to cache content, using the web.config file to set caching for all static content, and in IIS7 itself setting aching by file extension that gives you that extra level of granularity. Web.config: In IIS7, Expires Headers can be enabled in the system.webServer section of the web.config file:   <staticContent>     <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="1.00:00:00" />   </staticContent> In the above example a cache expiration of 1 day was added. It will be a full day before the content is downloaded from the web server again. To expire the content on a specific date:   <staticContent>     <clientCache cacheControlMode="UseExpires" httpExpires="Sun, 31 Dec 2011 23:59:59 UTC" />   </staticContent> This will expire the content on December 31st 2011 one second before midnight. Issues/Challenges: Once the file has been set to be cached it wont be updated on the user's browser for the set cache expiration. So be careful here with content that may change frequently, like during development. Typically in development you don't want to cache at all for testing purposes. You could also suffix files with timestamp or versions to force a reload into the user's browser cache. IIS7 Expire Web Content Open up your web app in IIS. Open up the sub-folders until you find the folder or file you want to ad an expiration date to. In IIS6 you used to right-click and select properties, no such luck in IIS7, double click HTTP Response. Once the window loads for the HTTP Response Headers, look to the Actions navigation bar to the right, all the way at the top select SET COMMON HEADERS. The Enable HTTP keep-alive will already be pre-selected. Go ahead and add the appropriate expiration header to the file or folder. Note that if you selected a folder, it will apply that setting to all images inside that folder and all nested content, even subfolders. So, two approaches, depending on what level or granularity you need.

  • Wireless Network Found, can't connect, repeated requests for authentication

    - by Herm Holland
    After trawling through the internet, on forums, support websites, and through dozens upon dozens of answered questions on this site, I've not found a solution to what seems like a fairly regular problem... I cannot connect to a wireless network, and am continually asked for the network password. I have tried countless suggested solutions on the different locations I've already referred to. None of them have worked. Details of my experience are as follows: I have just recently installed Ubuntu 12.04.1 (32-bit). Ubuntu installed on my system seemingly fine, and I even formatted my hard drive during the process. It's as if it were a new desktop computer. During the installation I was asked to connect to a Wireless Network. I have a USB Wireless Card connected which I have used to connect desktop PC's, laptops, and a Wii to the internet from approximately the same area of the house (thus the same distance from the Wireless Router). I chose my network, entered the correct password for it (I double checked; it's definitely the right password) and proceeded with the installation. Several times before the installation was complete, I was asked to authenticate the connection, and this seemed to do nothing each time. On the repeated screens the password was already entered in the appropriate box. When Ubuntu booted up the first thing I was faced with (other than something about Language settings, or something) was another request for authentication. Again, the password was already there, so I clicked connect. It did not connect. Instead, I was once again faced with repeated requests every few minutes. I went onto my laptop, which is connected to this network, checked the details of the network, and entered them manually into my Ubuntu PC (including the IPv4 and IPv6 information) but this didn't work either, so I set it back to finding the settings automatically. Note, also, that the "Connect automatically" and "Available to all users" boxes are checked, and have been unchecked & rechecked countless times. I have also tried having my User account connect automatically, and to need a password entered at the welcome screen. Whilst I've been writing this, it has gone through a spat of connecting successfully to the network for less than a minute, before coming offline again, only to repeat the process. But it has now returned to prompting me for a password every couple of minutes. This computer has already run on the Fedora OS, and had no trouble connecting to, and maintaining a connection. I also have a laptop running Windows 7 less than a metre away from this desktop PC, which is connected and has no trouble maintaining a connection at 50%-100% strength (fluctuating). Therefore: - I know it's not the wireless card - I know it's not the PC itself - I know it's not the access point - I know it's not the location of my PC or wireless card - It is solely because of Ubuntu Everything else has worked fine, but the moment Ubuntu was introduced into the equation, it has gone completely wrong. Honestly; I prefer Ubuntu as an OS to Fedora, but if I can't solve the problem it'll be straight back to Fedora that I'll have to go. Can anyone help me at all?

Scripts calling Node.js as a shell command must be changed to instead use the "nodejs" command.

  • Content Challenge: You Can Only Get it Here

    - by Mike Stiles
    Part of the content conundrum for brands is figuring out what kind of content customers would find cool, desirable, and relevant. The mere fact many brands have no idea what this content might be is, in itself, pretty alarming. You’d have to have a pretty thorough lack of involvement with and understanding of your customers to not know what they might like. But despite what should be a great awakening in which consumers are using every technology and trick in the book to shield themselves from ads and commercials, brand self-obsession continues as marketers concentrate on their message, their campaign, what they want to say, and what they want social users to do. When individuals conduct themselves in that same fashion on Facebook and Twitter, it gets tiresome and starts losing value pretty quickly. Their posts eventually get hidden. Conversely, friends who post things that consistently entertain or inform, with little self-marketing desperation involved, win the coveted “show all updates” setting. Of course brands are going to use social to market. It’s pretty much the point of having social in the marketing mix. And yes, people who follow a brand’s Twitter account or “Like” a brand’s Facebook Page implicitly state they want to know what’s going on with that brand’s products and services. But if you have a Facebook friend that assumes you want every one of her posts to be about what wine she likes (Mitsubishi’s current campaign is even based around weeding out pretentious Facebook friends, then running them over), then you know how it must feel for your fans and followers to get a sales pitch for your crackers or whatever you’re selling every single time. Is there such a thing as content that doesn’t sell but that still advances the brand and makes the consumer more involved and valuable? Of course. And perhaps there are no better companies than enterprise brands to do it. Enterprise organizations are large enough to go beyond a product and engage readers/viewers at higher, broader levels…communicating expertise across entire sectors, subjects and industries. You’re going from pitchman to news source, and getting full credit for it as the presenter. A recent GigaOM article pointed out the success a San Francisco-based startup called Crunchyroll is having. Their niche (and they proudly admit it’s a niche) is providing Japanese anime, Korean drama and Asian live action content to countries that can’t get it any other way via licensing deals. Shows are available in HD and on the same day they air in the host country. Crunchyroll not only gets 8 million viewers a month, they have 100,000 paying subscribers at $7-12/month. Got a point, Mike? I do happen to have one. Crunchyroll illustrates the content opportunity enterprise companies have…which is to determine your “area,” the interest graph of your customers, then provide content that speaks to and satisfies those interests that can’t be found anywhere else. At least not in the same style, or of the same quality, or with the same authority. Do what no one else is doing. Provide what no one else is providing in your sector. If underserved users are willing to pay monthly for access to awkwardly moving cartoon dragons, imagine the audience you could attract with free, useful, non-sales content in your customers’ area of interest. It’s an audience you’ll want in place when the time does come to put out that marketing message. A content challenge is better than a content conundrum any day.

  • Copying A Slide From One Presentation To Another

    - by Tim Murphy
    There are many ways to generate a PowerPoint presentation using Open XML.  The first way is to build it by hand strictly using the SDK.  Alternately you can modify a copy of a base presentation in place.  The third approach to generate a presentation is to build a new presentation from the parts of an existing presentation by copying slides as needed.  This post will focus on the third option. In order to make this solution a little more elegant I am going to create a VSTO add-in as I did in my previous post.  This one is going to insert Tags to identify slides instead of NonVisualDrawingProperties which I used to identify charts, tables and images.  The code itself is fairly short. SlideNameForm dialog = new SlideNameForm(); Selection selection = Globals.ThisAddIn.Application.ActiveWindow.Selection;   if(dialog.ShowDialog() == DialogResult.OK) { selection.SlideRange.Tags.Add(dialog.slideName,dialog.slideName); } Zeyad Rajabi has a good post here on combining slides from two presentations.  The example he gives is great if you are doing a straight merge.  But what if you want to use your source file as almost a supermarket where you pick and chose slides and may even insert them repeatedly?  The following code uses the tags we created in the previous step to pick a particular slide an copy it to a destination file. using (PresentationDocument newDocument = PresentationDocument.Open(OutputFileText.Text,true)) { PresentationDocument templateDocument = PresentationDocument.Open(FileNameText.Text, false);   uniqueId = GetMaxIdFromChild(newDocument.PresentationPart.Presentation.SlideMasterIdList); uint maxId = GetMaxIdFromChild(newDocument.PresentationPart.Presentation.SlideIdList);   SlidePart oldPart = GetSlidePartByTagName(templateDocument, SlideToCopyText.Text);   SlidePart newPart = newDocument.PresentationPart.AddPart<SlidePart>(oldPart, "sourceId1");   SlideMasterPart newMasterPart = newDocument.PresentationPart.AddPart(newPart.SlideLayoutPart.SlideMasterPart);   SlideIdList idList = newDocument.PresentationPart.Presentation.SlideIdList;   // create new slide ID maxId++; SlideId newId = new SlideId(); newId.Id = maxId; newId.RelationshipId = "sourceId1"; idList.Append(newId);   // Create new master slide ID uniqueId++; SlideMasterId newMasterId = new SlideMasterId(); newMasterId.Id = uniqueId; newMasterId.RelationshipId = newDocument.PresentationPart.GetIdOfPart(newMasterPart); newDocument.PresentationPart.Presentation.SlideMasterIdList.Append(newMasterId);   // change slide layout ID FixSlideLayoutIds(newDocument.PresentationPart);     //newPart.Slide.Save(); newDocument.PresentationPart.Presentation.Save(); } The GetMaxIDFromChild and FixSlideLayoutID methods are barrowed from Zeyad’s article.  The GetSlidePartByTagName method is listed below.  It is really one LINQ query that finds SlideParts with child Tags that have the requested Name. private SlidePart GetSlidePartByTagName(PresentationDocument templateDocument, string tagName) { return (from p in templateDocument.PresentationPart.SlideParts where p.UserDefinedTagsParts.First().TagList.Descendants <DocumentFormat.OpenXml.Presentation.Tag>().First().Name == tagName.ToUpper() select p).First(); } This is what really makes the difference from what Zeyad posted.  The most powerful thing you can have when generating documents from templates is a consistent way of naming items to be manipulated.  I will be show more approaches like this in upcoming posts. del.icio.us Tags: Office Open XML,Presentation,PowerPoint,VSTO,TagList

  • SQL SERVER – What are Actions in SSAS and How to Make a Reporting Action

    - by Pinal Dave
    Actions are used for customized browsing and drilling of data for the end-user. It’s an event that a user can raise while accessing the cube data. They are used in cube browsers like excel and are triggered when a user in a client tool clicks on a particular member, level, dimension, cells or may be the cube itself.  For example a user might be able to see a reporting services report, open a web page or drill through to detailed information related to the cube data. Analysis server supports 3 types of actions :- Report Drill-through Standard Actions In this blog post, I will explain the Reporting  action. The objective of this action is to return a report with details of the product where the sales amount is greater than 1000 in cube browser analysis. You need to create a basic cube first with the facts and dimensions you want in the analysis. Following are the steps to create reporting action. Go to SQL server data tools and open the analysis services project. Navigate to actions and click on new reporting action. 2.) Specify the name of the action and choose target type as attribute members since we have to create the action on members for a attribute. 3.) Specify the Target object of your report action. Target object would be the dimension or attribute on which you want the report to appear. In our case it is product name. 4.) Next you have to define the condition on which you want the report link to appear. However, this is an optional feature. In this example we are specifying a condition, which will check if the sales amount is greater than 10,000. So, that the link appears only for those products where the defined condition is met. 5.) Next you have to specify the server name on which the report is present, report path  and the report format in which you want the report to appear. 6.) Additionally you can specify the parameters. As with conditional expression, the parameters should be a valid MDX expression. The parameter name should be same as the one defined in the report. 7.) Deploy your solution after you are done with specifying parameters and go to the cube browser. 8.) Click on the analyze in excel button, this will open your cube in excel 9.) Make an analysis which shows product names and their sales amount. 10.) Right click on a product where sales amount is greater than 10000 you will see the reporting action link. Click on that and you will be taken to your reporting services report. 11.) Clicking on the link will take you to the URL of the report. I created this report using report project wizard in SQL server data tools. So, this is how we can launch reports from a cube browser. Similarly you can open web pages, run applications and a number of  other tasks. Koenig Solutions offers SSAS training which contains all Analysis Services including Reporting in great detail. In my next blog post I will talk about drill-through actions. Author: Namita Sharma, Senior Corporate Trainer at Koenig Solutions.

  • SSIS - Connect to Oracle on a 64-bit machine (Updated for SSIS 2008 R2)

    - by jorg
    We recently had a few customers where a connection to Oracle on a 64 bit machine was necessary. A quick search on the internet showed that this could be a big problem. I found all kind of blog and forum posts of developers complaining about this. A lot of developers will recognize the following error message: Test connection failed because of an error in initializing provider. Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed. After a lot of searching, trying and debugging I think I found the right way to do it! Problems Because BIDS is a 32 bit application, as well on 32 as on 64 bit machines, it cannot see the 64 bit driver for Oracle. Because of this, connecting to Oracle from BIDS on a 64 bit machine will never work when you install the 64 bit Oracle client. Another problem is the "Microsoft Provider for Oracle", this driver only exists in a 32 bit version and Microsoft has no plans to create a 64 bit one in the near future. The last problem I know of is in the Oracle client itself, it seems that a connection will never work with the instant client, so always use the full client. There are also a lot of problems with the 10G client, one of it is the fact that this driver can't handle the "(x86)" in the path of SQL Server. So using the 10G client is no option! Solution Download the Oracle 11G full client. Install the 32 AND the 64 bit version of the 11G full client (Installation Type: Administrator) and reboot the server afterwards. The 32 bit version is needed for development from BIDS with is 32 bit, the 64 bit version is needed for production with the SQLAgent, which is 64 bit. Configure the Oracle clients (both 32 and 64 bits) by editing  the files tnsnames.ora and sqlnet.ora. Try to do this with an Oracle DBA or, even better, let him/her do this. Use the "Oracle provider for OLE DB" from SSIS, don't use the "Microsoft Provider for Oracle" because a 64 bit version of it does not exist. Schedule your packages with the SQLAgent. Background information Visual Studio (BI Dev Studio)is a 32bit application. SQL Server Management Studio is a 32bit application. dtexecui.exe is a 32bit application. dtexec.exe has both 32bit and 64bit versions. There are x64 and x86 versions of the Oracle provider available. SQLAgent is a 64bit process. My advice to BI consultants is to get an Oracle DBA or professional for the installation and configuration of the 2 full clients (32 and 64 bit). Tell the DBA to download the biggest client available, this way you are sure that they pick the right one ;-) Testing if the clients have been installed and configured in the right way can be done with Windows ODBC Data Source Administrator: Start... Programs... Administrative tools... Data Sources (ODBC) ADITIONAL STEPS FOR SSIS 2008 R2 It seems that, unfortunately, some additional steps are necessary for SQL Server 2008 R2 installations: 1. Open REGEDIT (Start… Run… REGEDIT) on the server and search for the following entry (for the 32 bits driver): HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC\MTxOCI Make sure the following values are entered: 2. Next, search for (for the 64 bits driver): HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\MSDTC\MTxOCI Make sure the same values as above are entered. 3. Reboot your server.

  • virtual host not working in windows7 xampp

    - by K.B Panamaldeniya-littletipz
    hi i am using windows7 and xampp , i want to create a virtual host . so i added 127.0.0.1 myawesomeproject to my C:\Windows\System32\drivers\etc\hosts like this # Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host # localhost name resolution is handled within DNS itself. 127.0.0.1 localhost 127.0.0.1 myawesomeproject ::1 localhost and i added some lines to C:\xampp\apache\conf\extra\httpd-vhosts.conf like this # # Virtual Hosts # # If you want to maintain multiple domains/hostnames on your # machine you can setup VirtualHost containers for them. Most configurations # use only name-based virtual hosts so the server doesn't need to worry about # IP addresses.

  • Upgrades in 5 Easy Pieces

    - by Anne R.
    Even though there are a few select tasks that I have to do once or twice a year, I can’t remember how to do them! Or where to find the bits and pieces to complete the task. So I love it when someone consolidates everything under one spot. That’s what the CRM On Demand team has done with the upgrade information. Specifically, they have: Provided a “one-stop” area for managing upgrades at your company. Broken down the upgrade process into 5 (yes, 5) steps. Explained when and how to perform each step with dates specific to your pod. Included details about each step, visible by expanding the step. Translated the steps into 11 languages. Added a list of release-specific resources with links from the page. Now, just head for the Training and Support portal, click the Release Info tab, and walk through the “5 Essential Steps to a Successful Upgrade.” Before you continue, though, select your language from the drop-down list on the Release Info page. CRM On Demand now has the upgrade steps translated into 11 languages. On the Step page, you can expand each section in sequence and follow the more detailed instructions that appear. This will ensure that you’ve covered all your bases for each upgrade. Here’s a shortened version of the information that you’ll find: 1. Verify your Primary Contact Information. Have you checked your primary contact information to make sure you’re being notified of all upgrade information? Or do you want more users to receive upgrade announcements? This section provides you with the navigation path to do that in CRM On Demand. 2. Review your Key Upgrade Dates. If you expand this step, a nice table appears with your critical dates for the various milestones. IMPORTANT: When your CRM On Demand pod has been officially added to the upgrade schedule, closer to the release date itself, this table will display your specific timetable. 3. Migrate your Customizations from the Staging Environment before the Snapshot Date. Oracle refreshes the Staging data with a copy of your Production data made on the Production Snapshot Date. So this section lists considerations relevant to this step. It also reminds you of the 2-week period when you should not be making any changes in your Staging environment.   4. Conduct your Upgrade Validation on the Staging Environment. When the Customer Validation Testing period begins, you need to log in to your Staging Environment to validate that your key business processes and customizations continue to behave as expected. If your company utilizes Web Services, Web Links, Web Applets or Workflow, focus on testing these first. You generally have about two weeks for testing. If you run into problems during this time, follow the instructions shown in this section for logging a service request. It describes exactly how to fill out the fields in the SR for the fastest resolution. 5. Conduct "White Glove" Testing in your Upgraded Production Environment. Before users start using the upgrade, you should access a few tabs and reports. Doing this actually warms up the cache so that frequently used pages and reports will come up at normal speed on Monday morning, when users log in to the upgraded system. Resources listed under this step help you in further preparing for the upgrade. Now there’s also a new Documentation section on the right with links to these release-specific resources.   Very nice, I commented, when discussing these improvements with the “responsible party.” She confirmed that, yes, they tried to consolidate the upgrade information, translate it for better communication, simplify it into 5 easy pieces, and drive admins responsible for handling upgrades to this one site instead of sending out elaborate emails. Yes, I just love it when someone practically reaches out and holds my hand through a process. Next best thing to a wizard!

  • Impressions of my ASUS eee slate EP121 - Dual core 4GB, 64GB SSD

    - by tonyrogerson
    This thing is lovely, very nice bluetooth keyboard that has nice feedback on the keypress, there is no mouse but you can use the stylus or get yourself a bluetooth mouse, me, I've opted for a Microsoft ARC mouse which is a delight to use, the USB doors are a pain to open for the first time if like me you don't have any finger nails. It came as a suprise that the slate shows four processors, Dual Core with multi-threading, I didn't really look at the processor I was more interested in the amount of memory and the SSD; you don't get the full 4GB even with the 64 bit version of Windows 7 installed (which I immediately upgraded to Ultimate through my MSDN subscription). The box is extremely responsive - extremely, it loads Winword in literally a second. I've got office 2010 and onenote 2010 on there now; one problem is that on applying all (43) windows updates since the upgrade the machine is still sat on step 3 of 3 on the start up configuring updates screen after about an hour, you can't turn this machine off without using a paper clip to reset it and as I have just found you need a paper clip :). Installing Windows 7 SP1 was effortless. One of the first things I did on it was to reduce the size of the font, by default its set at 125%, my eye sight is ok :) so I've set that back down. Amazon Kindle for the PC works really well, plenty of text on the screen when viewed portrait, the case it comes with also allows the slate to stand up in various positions - portrait, horizontal - seems stable enough. The wireless works well, seems to have a better signal than my other two laptop machines which is good news. The gadget passed the pose test at work :). I use offline files to keep a copy of all my work stuff locally, I'm not sure what it is, well, its probably my server but whenever I try and sync it runs for a couple of minutes then fails with network name no longer contactable, funnily enough its fine from my big laptop so I can only guess this may be a driver type issue on the EP121 itself - very odd and very annoying. I do a lot of presenting and need to plug into a VGA project because most sites that's all that is offered, the EP121 has a mini-hdmi output which is great except for this scenario, hdmi is digital, vga is analogue, you will struggle to find a cost effective solution, I found HDFury and also a device HP do, however, a better solution appears to be getting a USB graphics adapter for instance the one I've ordered is the ClimaxDigital USB 2.0 to DVI,VGA or HDMI Adaptor which gives everything I need - VGA and DVI output and great resolution as well - ok, so fingers crossed because I'm presenting next Wednesday in Edinburgh and not taking my 300kg lenovo w700 (I'm sure my back just sighed in relief) - it certainly works really well on my LED TV, the install was simple - it just works! One of the several reasons for buying this piece of kit was to use it on my LED TV to remote into my main machine to check stuff whilst sat in my living room, also to watch webcasts and lecture videos in comfort away from my office, because of the wireless speed and limitation I'm opting for a USB network adapter from Belkin - that will also allow me to take advantage of my home gigabit network, there are only 2 usb ports on the slate so I'm going to knock up a hub so connecting it in is straight forward and simple, I'm also going to purchase a second power supply so I don't have to faff about with that either.I now have the developer x64 edition of SQL Server 2008 R2, yes everything :) - about 16GB left to play with on the machine now but that will be fine, I'll put AdventureWorks on there so I can play and demo stuff which is all I'm after from this, my development machine is significantly more powerful and meets my storage needs too.Travel test this weekend and next week, I'm in Dundee for my final exam for the masters degree.

  • Why would Copying a Large Image to the Clipboard Freeze a Computer?

    - by Akemi Iwaya
    Sometimes, something really odd happens when using our computers that makes no sense at all…such as copying a simple image to the clipboard and the computer freezing up because of it. An image is an image, right? Today’s SuperUser post has the answer to a puzzled reader’s dilemna. Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. Original image courtesy of Wikimedia. The Question SuperUser reader Joban Dhillon wants to know why copying an image to the clipboard on his computer freezes it up: I was messing around with some height map images and found this one: (http://upload.wikimedia.org/wikipedia/commons/1/15/Srtm_ramp2.world.21600×10800.jpg) The image is 21,600*10,800 pixels in size. When I right click and select “Copy Image” in my browser (I am using Google Chrome), it slows down my computer until it freezes. After that I must restart. I am curious about why this happens. I presume it is the size of the image, although it is only about 6 MB when saved to my computer. I am also using Windows 8.1 Why would a simple image freeze Joban’s computer up after copying it to the clipboard? The Answer SuperUser contributor Mokubai has the answer for us: “Copy Image” is copying the raw image data, rather than the image file itself, to your clipboard. The raw image data will be 21,600 x 10,800 x 3 (24 bit image) = 699,840,000 bytes of data. That is approximately 700 MB of data your browser is trying to copy to the clipboard. JPEG compresses the raw data using a lossy algorithm and can get pretty good compression. Hence the compressed file is only 6 MB. The reason it makes your computer slow is that it is probably filling your memory up with at least the 700 MB of image data that your browser is using to show you the image, another 700 MB (along with whatever overhead the clipboard incurs) to store it on the clipboard, and a not insignificant amount of processing power to convert the image into a format that can be stored on the clipboard. Chances are that if you have less than 4 GB of physical RAM, then those copies of the image data are forcing your computer to page memory out to the swap file in an attempt to fulfil both memory demands at the same time. This will cause programs and disk access to be sluggish as they use the disk and try to use the data that may have just been paged out. In short: Do not use the clipboard for huge images unless you have a lot of memory and a bit of time to spare. Like pretty graphs? This is what happens when I load that image in Google Chrome, then copy it to the clipboard on my machine with 12 GB of RAM: It starts off at the lower point using 2.8 GB of RAM, loading the image punches it up to 3.6 GB (approximately the 700 MB), then copying it to the clipboard spikes way up there at 6.3 GB of RAM before settling back down at the 4.5-ish you would expect to see for a program and two copies of a rather large image. That is a whopping 3.7 GB of image data being worked on at the peak, which is probably the initial image, a reserved quantity for the clipboard, and perhaps a couple of conversion buffers. That is enough to bring any machine with less than 8 GB of RAM to its knees. Strangely, doing the same thing in Firefox just copies the image file rather than the image data (without the scary memory surge). Have something to add to the explanation? Sound off in the comments.

  • Live Event: OTN Architect Day: Cloud Computing - Two weeks and counting

    - by Bob Rhubart
    In just two weeks architects and others will gather at the Oracle Conference Center in Redwood Shores, CA for the first Oracle Technology Network Architect Day event of 2013. This event focuses on Cloud Computing, and features sessions specifically focused on real-world examples of the implementation of cloud computing. When: Tuesday July 9, 2013              8:30am - 12:30pm Where: Oracle Conference Center              350 Oracle Pkwy              Redwood City, CA 94065 Register now. It's free! Here's the agenda: 8:30am - 9:00am Registration and Continental Breakfast 9:00am - 9:45am Keynote 21st Century IT | Dr. James Baty VP, Global Enterprise Architecture Program, Oracle Imagine a time long, long ago. A time when servers were certified and dedicated to specific applications, when anything posted on an enterprise web site was from restricted, approved channels, and when we tried to limit the growth of 'dirty' data and storage. Today, applications are services running in the muti-tenant hybrid cloud. Companies beg their customers to tweet them, friend them, and publicly rate their products. And constantly analyzing a deluge of Internet, social and sensor data is the key to creating the next super-successful product, or capturing an evil terrorist. The old IT architecture was planned, dedicated, stable, controlled, with separate and well-defined roles. The new architecture is shared, dynamic, continuous, XaaS, DevOps. This keynote session describes the challenges and opportunities that the new business / IT paradigms present to the IT architecture and architects. 9:45am - 10:30am Technical Session Oracle Cloud: A Case Study in Building a Cloud | Anbu Krishnaswami Enterprise Architect, Oracle Building a Cloud can be challenging thanks to the complex requirements unique to Cloud computing and the massive scale typically associated with Cloud. Cloud providers can take an Infrastructure as a Service (IaaS) approach and build a cloud on virtualized commodity hardware, or they can take the Platform as a Service (PaaS) path, a service-oriented approach based on pre-configured, integrated, engineered systems. This presentation uses the Oracle Cloud itself as a case study in the use of engineered systems, demonstrating how the technical design of engineered systems is leveraged for building PaaS and SaaS Cloud services and a Cloud management infrastructure. The presentation will also explore the principles, patterns, best practices, and architecture views provided in Oracle's Cloud reference architecture. 10:30 am -10:45 am Break 10:45am-11:30am Technical Session Database as a Service | Michael Timpanaro-Perrotta Director, Product Management, Oracle Database Cloud New applications are now commonly built in a Cloud model, where the database is consumed as a service, and many established business processes are beginning to migrate to database as a service (DBaaS). This adoption of DBaaS is made possible by the availability of new capabilities in the database that enable resource pooling, dynamic resource management, model-based provisioning, metered use, and effective quality-of-service controls. This session will examine the catalog of database services at a large commercial bank to understand how these capabilities are enabling DBaaS for a wide range of needs within the enterprise. 11:30 am - 12:00 pm Panel Q&A Dr. James Baty, Anbu Krishnaswami, and Michael Timpanaro-Perrotta respond to audience questions. Registration is free, but seating is limited, so register now.

  • WebLogic Server–Use the Execution Context ID in Applications–Lessons From Hansel and Gretel

    - by james.bayer
    I learned a neat trick this week.  Don’t let your breadcrumbs go to waste like Hansel and Gretel did!  Keep track of the code path, logs and errors for each request as they flow through the system.  Earlier this week an OTN forum post in the WLS – General category by Oracle Ace John Stegeman asked a question how to retrieve the Execution Context ID so that it could be used on an error page that a user could provide to a help desk or use to check with application administrators so they could look up what went wrong.  What is the Execution Context ID (ECID)?  Fusion Middleware injects an ECID as a request enters the system and it says with the request as it flows from Oracle HTTP Server to Oracle Web Cache to multiple WebLogic Servers to the Oracle Database. It’s a way to uniquely identify a request across tiers.  According to the documentation it’s: The value of the ECID is a unique identifier that can be used to correlate individual events as being part of the same request execution flow. For example, events that are identified as being related to a particular request typically have the same ECID value.  The format of the ECID string itself is determined by an internal mechanism that is subject to change; therefore, you should not have or place any dependencies on that format. The novel idea that I see John had was to extend this concept beyond the diagnostic information that is captured by Fusion Middleware.  Why not also use this identifier in your logs and errors so you can correlate even more information together!  Your logging might already identify the user, so why not identify the request so you filter down even more.  All you need to do inside of WebLogic Server to get ahold of this information is invoke DiagnosticConextHelper: weblogic.diagnostics.context.DiagnosticContextHelper.getContextId() This class has other helpful methods to see other values tracked by the diagnostics framework too.  This way I can see even more detail and get information across tiers. In performance profiling, this can be very handy to track down where time is being spent in code.  I’ve blogged and made videos about this before.  JRockit Flight Recorder can use the WLDF Diagnostic Volume in WLS 10.3.3+ to automatically capture and correlate lots of helpful information for each request without installing any special agents and with the out-of-the-box JRockit and WLS settings!  You can see here how information is displayed in JRockit Flight Recorder about a single request as it calls a Servlet, which calls an EJB, which gets a DB connection, which starts a transaction, etc.  You can get timings around everything and even see the SQL that is used. http://download.oracle.com/docs/cd/E21764_01/web.1111/e13714/using_flightrecorder.htm#WLDFC480 Recent versions of the WLS console also are able to visualize this data too, so it works with other JVMs besides JRockit when you turn on WLDF instrumentation. I wrote a little sample application that verified to myself that the ECID did actually cross JVM boundaries.  I invoked a Servlet in one JVM, which acted as an EJB client to Stateless Session Bean running in another JVM.  Each call returned the same ECID.  You need to turn on WLDF Instrumentation for this to work otherwise the framework returns null.  I’m glad John put me on to this API as I have some interesting ideas on how to correlate some information together.

  • C#: A "Dumbed-Down" C++?

    - by James Michael Hare
    I was spending a lovely day this last weekend watching my sons play outside in one of the better weekends we've had here in Saint Louis for quite some time, and whilst watching them and making sure no limbs were broken or eyes poked out with sticks and other various potential injuries, I was perusing (in the correct sense of the word) this month's MSDN magazine to get a sense of the latest VS2010 features in both IDE and in languages. When I got to the back pages, I saw a wonderful article by David S. Platt entitled, "In Praise of Dumbing Down"  (msdn.microsoft.com/en-us/magazine/ee336129.aspx).  The title captivated me and I read it and found myself agreeing with it completely especially as it related to my first post on divorcing C++ as my favorite language. Unfortunately, as Mr. Platt mentions, the term dumbing-down has negative connotations, but is really and truly a good thing.  You are, in essence, taking something that is extremely complex and reducing it to something that is much easier to use and far less error prone.  Adding safeties to power tools and anti-kick mechanisms to chainsaws are in some sense "dumbing them down" to the common user -- but that also makes them safer and more accessible for the common user.  This was exactly my point with C++ and C#.  I did not mean to infer that C++ was not a useful or good language, but that in a very high percentage of cases, is too complex and error prone for the job at hand. Choosing the correct programming language for a job is a lot like choosing any other tool for a task.  For example: if I want to dig a French drain in my lawn, I can attempt to use a huge tractor-like backhoe and the job would be done far quicker than if I would dig it by hand.  I can't deny that the backhoe has the raw power and speed to perform.  But you also cannot deny that my chances of injury or chances of severing utility lines or other resources climb at an exponential rate inverse to the amount of training I may have on that machinery. Is C++ a powerful tool?  Oh yes, and it's great for those tasks where speed and performance are paramount.  But for most of us, it's the wrong tool.  And keep in mind, I say this even though I have 17 years of experience in using it and feel myself highly adept in utilizing its features both in the standard libraries, the STL, and in supplemental libraries such as BOOST.  Which, although greatly help with adding powerful features quickly, do very little to curb the relative dangers of the language. So, you may say, the fault is in the developer, that if the developer had some higher skills or if we only hired C++ experts this would not be an issue.  Now, I will concede there is some truth to this.  Obviously, the higher skilled C++ developers you hire the better the chance they will produce highly performant and error-free code.  However, what good is that to the average developer who cannot afford a full stable of C++ experts? That's my point with C#:  It's like a kinder, gentler C++.  It gives you nearly the same speed, and in many ways even more power than C++, and it gives you a much softer cushion for novices to fall against if they code less-than-optimally.  A bug is a bug, of course, in any language, but C# does a good job of hiding and taking on the task of handling almost all of the resource issues that make C++ so tricky.  For my money, C# is much more maintainable, more feature-rich, second only slightly in performance, faster to market, and -- last but not least -- safer and easier to use.  That's why, where I work, I much prefer to see the developers moving to C#.  The quantity of bugs is much lower, and we don't need to hire "experts" to achieve the same results since the language itself handles those resource pitfalls so prevalent in poorly written C++ code.  C++ will still have its place in the world, and I'm sure I'll still use it now and again where it is truly the correct tool for the job, but for nearly every other project C# is a wonderfully "dumbed-down" version of C++ -- in the very best sense -- and to me, that's the smart choice.

  • EF4 Code First Control Unicode and Decimal Precision, Scale with Attributes

    - by Dane Morgridge
    There are several attributes available when using code first with the Entity Framework 4 CTP5 Code First option.  When working with strings you can use [MaxLength(length)] to control the length and [Required] will work on all properties.  But there are a few things missing. By default all string will be created using unicode so you will get nvarchar instead of varchar.  You can change this using the fluent API or you can create an attribute to make the change.  If you have a lot of properties, the attribute will be much easier and require less code. You will need to add two classes to your project to create the attribute itself: 1: public class UnicodeAttribute : Attribute 2: { 3: bool _isUnicode; 4:  5: public UnicodeAttribute(bool isUnicode) 6: { 7: _isUnicode = isUnicode; 8: } 9:  10: public bool IsUnicode { get { return _isUnicode; } } 11: } 12:  13: public class UnicodeAttributeConvention : AttributeConfigurationConvention<PropertyInfo, StringPropertyConfiguration, UnicodeAttribute> 14: { 15: public override void Apply(PropertyInfo memberInfo, StringPropertyConfiguration configuration, UnicodeAttribute attribute) 16: { 17: configuration.IsUnicode = attribute.IsUnicode; 18: } 19: } The UnicodeAttribue class gives you a [Unicode] attribute that you can use on your properties and the UnicodeAttributeConvention will tell EF how to handle the attribute. You will need to add a line to the OnModelCreating method inside your context for EF to recognize the attribute: 1: protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder) 2: { 3: modelBuilder.Conventions.Add(new UnicodeAttributeConvention()); 4: base.OnModelCreating(modelBuilder); 5: } Once you have this done, you can use the attribute in your classes to make sure that you get database types of varchar instead of nvarchar: 1: [Unicode(false)] 2: public string Name { get; set; }   Another option that is missing is the ability to set the precision and scale on a decimal.  By default decimals get created as (18,0).  If you need decimals to be something like (9,2) then you can once again use the fluent API or create a custom attribute.  As with the unicode attribute, you will need to add two classes to your project: 1: public class DecimalPrecisionAttribute : Attribute 2: { 3: int _precision; 4: private int _scale; 5:  6: public DecimalPrecisionAttribute(int precision, int scale) 7: { 8: _precision = precision; 9: _scale = scale; 10: } 11:  12: public int Precision { get { return _precision; } } 13: public int Scale { get { return _scale; } } 14: } 15:  16: public class DecimalPrecisionAttributeConvention : AttributeConfigurationConvention<PropertyInfo, DecimalPropertyConfiguration, DecimalPrecisionAttribute> 17: { 18: public override void Apply(PropertyInfo memberInfo, DecimalPropertyConfiguration configuration, DecimalPrecisionAttribute attribute) 19: { 20: configuration.Precision = Convert.ToByte(attribute.Precision); 21: configuration.Scale = Convert.ToByte(attribute.Scale); 22:  23: } 24: } Add your line to the OnModelCreating: 1: protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder) 2: { 3: modelBuilder.Conventions.Add(new UnicodeAttributeConvention()); 4: modelBuilder.Conventions.Add(new DecimalPrecisionAttributeConvention()); 5: base.OnModelCreating(modelBuilder); 6: } Now you can use the following on your properties: 1: [DecimalPrecision(9,2)] 2: public decimal Cost { get; set; } Both these options use the same concepts so if there are other attributes that you want to use, you can create them quite simply.  The key to it all is the PropertyConfiguration classes.   If there is a class for the datatype, then you should be able to write an attribute to set almost everything you need.  You could also create a single attribute to encapsulate all of the possible string combinations instead of having multiple attributes on each property. All in all, I am loving code first and having attributes to control database generation instead of using the fluent API is huge and saves me a great deal of time.

    I have some serious problems with Technaxx pci-e 302p card. It has uPD720200a NEC chip with 4020 firmware. BIOS recognises it. Sometimes it recognises devices and system mounts them and are functional for few minutes, other times they can't be mount and error occours. After fresh install card worked fine, but after kernel and firmware update it behaves as mentioned.

  • Visual Studio Extensions

    - by Scott Dorman
    Originally posted on: http://geekswithblogs.net/sdorman/archive/2013/10/18/visual-studio-extensions.aspxAs a product, Visual Studio has been around for a long time. In fact, it’s been 18 years since the first Visual Studio product was launched. In that time, there have been some major changes but perhaps the most important (or at least influential) changes for the course of the product have been in the last few years. While we can argue over what was and wasn’t an important change or what has and hasn’t changed, I want to talk about what I think is the single most important change Microsoft has made to Visual Studio. Specifically, I’m referring to the Visual Studio Gallery (first introduced in Visual Studio 2010) and the ability for third-parties to easily write extensions which can add new functionality to Visual Studio or even change existing functionality. I know Visual Studio had this ability before the Gallery existed, but it was expensive (both from a financial and development resource) perspective for a company or individual to write such an extension. The Visual Studio Gallery changed all of that. As of today, there are over 4000 items in the Gallery. Microsoft itself has over 100 items in the Gallery and more are added all of the time. Why is this such an important feature? Simply put, it allows third-parties (companies such as JetBrains, Telerik, Red Gate, Devart, and DevExpress, just to name a few) to provide enhanced developer productivity experiences directly within the product by providing new functionality or changing existing functionality. However, there is an even more important function that it serves. It also allows Microsoft to do the same. By providing extensions which add new functionality or change existing functionality, Microsoft is not only able to rapidly innovate on new features and changes but to also get those changes into the hands of developers world-wide for feedback. The end result is that these extensions become very robust and often end up becoming part of a later product release. An excellent example of this is the new CodeLens feature of Visual Studio 2013. This is, perhaps, the single most important developer productivity enhancement released in the last decade and already has huge potential. As you can see, out of the box CodeLens supports showing you information about references, unit tests and TFS history.   Fortunately, CodeLens is also accessible to Visual Studio extensions, and Microsoft DevLabs has already written such an extension to show code “health.” This extension shows different code metrics to help make sure your code is maintainable. At this point, you may have already asked yourself, “With over 4000 extensions, how do I find ones that are good?” That’s a really good question. Fortunately, the Visual Studio Gallery has a ratings system in place, which definitely helps but that’s still a lot of extensions to look through. To that end, here is my personal list of favorite extensions. This is something I started back when Visual Studio 2010 was first released, but so much has changed since then that I thought it would be good to provide an updated list for Visual Studio 2013. These are extensions that I have installed and use on a regular basis as a developer that I find indispensible. This list is in no particular order. NuGet Package Manager for Visual Studio 2013 Microsoft CodeLens Code Health Indicator Visual Studio Spell Checker Indent Guides Web Essentials 2013 VSCommands for Visual Studio 2013 Productivity Power Tools (right now this is only for Visual Studio 2012, but it should be updated to support Visual Studio 2013.) Everyone has their own set of favorites, so mine is probably not going to match yours. If there is an extension that you really like, feel free to leave me a comment!

  • DataContractSerializer: type is not serializable because it is not public?

    - by Michael B. McLaughlin
    I recently ran into an odd and annoying error when working with the DataContractSerializer class for a WP7 project. I thought I’d share it to save others who might encounter it the same annoyance I had. So I had an instance of  ObservableCollection<T> that I was trying to serialize (with T being a class I wrote for the project) and whenever it would hit the code to save it, it would give me: The data contract type 'ProjectName.MyMagicItemsClass' is not serializable because it is not public. Making the type public will fix this error. Alternatively, you can make it internal, and use the InternalsVisibleToAttribute attribute on your assembly in order to enable serialization of internal members - see documentation for more details. Be aware that doing so has certain security implications. This, of course, was malarkey. I was trying to write an instance of MyAwesomeClass that looked like this: [DataContract] public class MyAwesomeClass { [DataMember] public ObservableCollection<MyMagicItemsClass> GreatItems { get; set; }   [DataMember] public ObservableCollection<MyMagicItemsClass> SuperbItems { get; set; }     public MyAwesomeClass { GreatItems = new ObservableCollection<MyMagicItemsClass>(); SuperbItems = new ObservableCollection<MyMagicItemsClass>(); } }   That’s all well and fine. And MyMagicItemsClass was also public with a parameterless public constructor. It too had DataContractAttribute applied to it and it had DataMemberAttribute applied to all the properties and fields I wanted to serialize. Everything should be cool, but it’s not because I keep getting that “not public” exception. I could tell you about all the things I tried (generating a List<T> on the fly to make sure it wasn’t ObservableCollection<T>, trying to serialize the the Collections directly, moving it all to a separate library project, etc.), but I want to keep this short. In the end, I remembered my the “Debug->Exceptions…” VS menu option that brings up the list of exception-related circumstances under which the Visual Studio debugger will break. I checked the “Thrown” checkbox for “Common Language Runtime Exceptions”, started the project under the debugger, and voilà: the true problem revealed itself. Some of my properties had fairly elaborate setters whose logic I wanted to ignore. So for some of them, I applied an IgnoreDataMember attribute to them and applied the DataMember attribute to the underlying fields instead. All of which, in line with good programming practices, were private. Well, it just so happens that WP7 apps run in a “partial trust” environment and outside of “full trust”-land, DataContractSerializer refuses to serialize or deserialize non-public members. Of course that exception was swallowed up internally by .NET so all I ever saw was that bizarre message about things that I knew for certain were public being “not public”. I changed all the private fields I was serializing to public and everything worked just fine. In hindsight it all makes perfect sense. The serializer uses reflection to build up its graph of the object in order to write it out. In partial trust, you don’t want people using reflection to get at non-public members of an object since there are potential security problems with allowing that (you could break out of the sandbox pretty quickly by reflecting and calling the appropriate methods and cause some havoc by reflecting and setting the appropriate fields in certain circumstances. The fact that you cannot reflect your own assembly seems a bit heavy-handed, but then again I’m not a compiler writer or a framework designer and I have no idea what sorts of difficulties would go into allowing that from a compilation standpoint or what sorts of security problems allowing that could present (if any). So, lesson learned. If you get an incomprehensible exception message, turn on break on all thrown exceptions and try running it again (it might take a couple of tries, depending) and see what pops out. Chances are you’ll find the buried exception that actually explains what was going on. And if you’re getting a weird exception when trying to use DataContractSerializer complaining about public types not being public, chances are you’re trying to serialize a private or protected field/property.

  • Oracle MDM Maturity Model

    - by David Butler
    A few weeks ago, I discussed the results of a survey conducted by Oracle’s Insight team. The survey was based on the data management maturity model that the Oracle Insight team has developed over the years as they analyzed customer IT organizations to help them get more out of everything they already have. I thought you might like to learn more about the maturity model itself. It can help you figure out where you stand when it comes to getting your organizations data management act together. The model covers maturity levels around five key areas: Profiling data sources; Defining a data strategy; Defining a data consolidation plan; Data maintenance; and Data utilization. Profile data sources: Profiling data sources involves taking an inventory of all data sources from across your IT landscape. Then evaluate the quality of the data in each source system. This enables the scoping of what data to collect into an MDM hub and what rules are needed to insure data harmonization across systems. Define data strategy: A data strategy requires an understanding of the data usage. Given data usage, various data governance requirements need to be developed. This includes data controls and security rules as well as data structure and usage policies. Define data consolidation strategy: Consolidation requires defining your operational data model. How integration is to be accomplished. Cross referencing common data attributes from multiple systems is needed. Synchronization policies also need to be developed. Data maintenance: The desired standardization needs to be defined, including what constitutes a ‘match’ once the data has been standardized. Cleansing rules are a part of this methodology. Data quality monitoring requirements also need to be defined. Utilize the data: What data gets published, and who consumes the data must be determined. How to get the right data to the right place in the right format given its intended use must be understood. Validating the data and insuring security rules are in place and enforced are crucial aspects for full no-risk data utilization. For each of the above data management areas, a maturity level needs to be assessed. Where your organization wants to be should also be identified using the same maturity levels. This results in a sound gap analysis your organization can use to create action plans to achieve the ultimate goals. Marginal is the lowest level. It is characterized by manually maintaining trusted sources; lacking or inconsistent, silo’d structures with limited integration, and gaps in automation. Stable is the next leg up the MDM maturity staircase. It is characterized by tactical MDM implementations that are limited in scope and target a specific division.  It includes limited data stewardship capabilities as well. Best Practice is a serious MDM maturity level characterized by process automation improvements. The scope is enterprise wide. It is a business solution that provides a single version of the truth, with closed-loop data quality capabilities. It is typically driven by an enterprise architecture group with both business and IT representation.   Transformational is the highest MDM maturity level. At this level, MDM is quantitatively managed. It is integrated with Business Intelligence, SOA, and BPM. MDM is leveraged in business process orchestration. Take an inventory using this MDM Maturity Model and see where you are in your journey to full MDM maturity with all the business benefits that accrue to organizations who have mastered their data for the benefit of all operational applications, business processes, and analytical systems. To learn more, Trevor Naidoo and I have written the Oracle MDM Maturity Model whitepaper. It’s free, so go ahead and download it and use it as you see fit.

  • Requesting feedback on my OO design

    - by Prog
    I'm working on an application that creates music by itself. I'm seeking feedback for my OO design so far. This question will focus on one part of the program. The application produces Tune objects, that are the final musical products. Tune is an abstract class with an abstract method play. It has two subclasses: SimpleTune and StructuredTune. SimpleTune owns a Melody and a Progression (chord sequence). It's play implementation plays these two objects simultaneously. StructuredTune owns two Tune instances. It's own play plays the two Tunes one after the other according to a pattern (currently only ABAB). Melody is an abstract class with an abstract play method. It has two subclasses: SimpleMelody and StructuredMelody. SimpleMelody is composed of an array of notes. Invoking play on it plays these notes one after the other. StructuredMelody is composed of an array of Melody objects. Invoking play on it plays these Melodyies one after the other. I think you're starting to see the pattern. Progression is also an abstract class with a play method and two subclasses: SimpleProgression and StructuredProgression, each composed differently and played differently. SimpleProgression owns an array of chords and plays them sequentially. StructuredProgression owns an array of Progressions and it's play implementation plays them sequentially. Every class has a corresponding Generator class. Tune, Melody and Progression are matched with corresponding abstract TuneGenerator, MelodyGenerator and ProgressionGenerator classes, each with an abstract generate method. For example MelodyGenerator defines an abstract Melody generate method. Each of the generators has two subclasses, Simple and Structured. So for example MelodyGenerator has a subclasses SimpleMelodyGenerator, with an implementation of generate that returns a SimpleMelody. (It's important to note that the generate methods encapsulate complex algorithms. They are more than mere factory method. For example SimpleProgressionGenerator.generate() implements an algorithm to compose a series of Chord objects, which are used to instantiate the returned SimpleProgression). Every Structured generator uses another generator internally. It is a Simple generator be default, but in special cases may be a Structured generator. Parts of this design are meant to allow the end-user through the GUI to choose what kind of music is to be created. For example the user can choose between a "simple tune" (SimpleTuneGenerator) and a "full tune" (StructuredTuneGenerator). Other parts of the system aren't subject to direct user-control. What do you think of this design from an OOD perspective? What potential problems do you see with this design? Please share with me your criticism, I'm here to learn. Apart from this, a more specific question: the "every class has a corresponding Generator class" part feels very wrong. However I'm not sure how I could design this differently and achieve the same flexibility. Any ideas?

  • Get to Know a Candidate (8 of 25): Rocky Anderson&ndash;Justice Party

    - by Brian Lanham
    DISCLAIMER: This is not a post about “Romney” or “Obama”. This is not a post for whom I am voting. Information sourced for Wikipedia. Ross Carl “Rocky” Anderson served two terms as the 33rd mayor of Salt Lake City, Utah, between 2000 and 2008.  He is the Executive Director of High Road for Human Rights.  Prior to serving as Mayor, he practiced law for 21 years in Salt Lake City, during which time he was listed in Best Lawyers in America, was rated A-V (highest rating) by Martindale-Hubbell, served as Chair of the Utah State Bar Litigation Section[4] and was Editor-in-Chief of, and a contributor to, Voir Dire legal journal. As mayor, Anderson rose to nationwide prominence as a champion of several national and international causes, including climate protection, immigration reform, restorative criminal justice, LGBT rights, and an end to the "war on drugs". Before and after the invasion by the U.S. of Iraq in 2003, Anderson was a leading opponent of the invasion and occupation of Iraq and related human rights abuses. Anderson was the only mayor of a major U.S. city who advocated for the impeachment of President George W. Bush, which he did in many venues throughout the United States. Anderson's work and advocacy led to local, national, and international recognition in numerous spheres, including being named by Business Week as one of the top twenty activists in the world on climate change,serving on the Newsweek Global Environmental Leadership Advisory Board, and being recognized by the Human Rights Campaign as one of the top ten straight advocates in the United States for LGBT equality. He has also received numerous awards for his work, including the EPA Climate Protection Award, the Sierra Club Distinguished Service Award, the Respect the Earth Planet Defender Award, the National Association of Hispanic Publications Presidential Award, The Drug Policy Alliance Richard J. Dennis Drugpeace Award, the Progressive Democrats of America Spine Award, the League of United Latin American Citizens Profile in Courage Award, the Bill of Rights Defense Committee Patriot Award, the Code Pink (Salt Lake City) Pink Star honor, the Morehouse University Gandhi, King, Ikeda Award, and the World Leadership Award for environmental programs. Formerly a member of the Democratic Party, Anderson expressed his disappointment with that Party in 2011, stating, “The Constitution has been eviscerated while Democrats have stood by with nary a whimper. It is a gutless, unprincipled party, bought and paid for by the same interests that buy and pay for the Republican Party." Anderson announced his intention to run for President in 2012 as a candidate for the newly-formed Justice Party. Although founded by Rocky Anderson of Utah, the Justice Party was first recognized by Mississippi and describes itself as advocating economic justice through measures such as green jobs and a right to organize, environment justice through enforcing employee safeguards in trade agreements, and social and civic justice through universal health care. In its first press release, the Utah Justice Party set forth its goals for justice in the economic, environmental, social and civic realms, along with a call to rid the corrupting influence of big money from government, to reverse the erosion of rights guaranteed by the Constitution, and to stop draining American resources to support illegal wars of aggression. Its press release says its grassroots supporters believe that now is the time for all to "shed their skeptical view that their voices don't matter", that "our 2-party system is a 'duopoly' controlled by the same corporate and military interests", and that the people must act to ensure "that our nation will achieve a brighter, sustainable future.” Anderson has ballot access in CO, CT, FL, ID, LA, MI, MN, MS, NJ, NM, OR, RI, TN, UT, VT, WA (152 electoral votes) and has write-in access in AL, AK, DE, GA, IL, IO, KS, MD, MO, NE, NH, NY, PA, TX Learn more about Rocky Anderson and Justice Party on Wikipedia.
