• Page output caching for dynamic web applications

  - by Mike Ellis

  I am currently working on a web application where the user steps (forward or back) through a series of pages with "Next" and "Previous" buttons, entering data until they reach a page with the "Finish" button. Until finished, all data is stored in Session state, then sent to the mainframe database via web services at the end of the process. Some of the pages display data from previous pages in order to collect additional information. These pages can never be cached because they are different for every user. For pages that don't display this dynamic data, they can be cached, but only the first time they load. After that, the data that was previously entered needs to be displayed. This requires Page_Load to fire, which means the page can't be cached at that point. A couple of weeks ago, I knew almost nothing about implementing page caching. Now I still don't know much, but I know a little bit, and here is the solution that I developed with the help of others on my team and a lot of reading and trial-and-error. We have a base page class defined from which all pages inherit. In this class I have defined a method that sets the caching settings programmatically. For pages that can be cached, they call this base page method in their Page_Load event within a if(!IsPostBack) block, which ensures that only the page itself gets cached, not the data on the page. if(!IsPostBack) {     ...     SetCacheSettings();     ... } protected void SetCacheSettings() {     Response.Cache.AddValidationCallback(new HttpCacheValidateHandler(Validate), null);     Response.Cache.SetExpires(DateTime.Now.AddHours(1));     Response.Cache.SetSlidingExpiration(true);     Response.Cache.SetValidUntilExpires(true);     Response.Cache.SetCacheability(HttpCacheability.ServerAndNoCache); } The AddValidationCallback sets up an HttpCacheValidateHandler method called Validate which runs logic when a cached page is requested. The Validate method signature is standard for this method type. public static void Validate(HttpContext context, Object data, ref HttpValidationStatus status) {     string visited = context.Request.QueryString["v"];     if (visited != null && "1".Equals(visited))     {         status = HttpValidationStatus.IgnoreThisRequest; //force a page load     }     else     {         status = HttpValidationStatus.Valid; //load from cache     } } I am using the HttpValidationStatus values IgnoreThisRequest or Valid which forces the Page_Load event method to run or allows the page to load from cache, respectively. Which one is set depends on the value in the querystring. The value in the querystring is set up on each page in the "Next" and "Previous" button click event methods based on whether the page that the button click is taking the user to has any data on it or not. bool hasData = HasPageBeenVisited(url); if (hasData) {     url += VISITED; } Response.Redirect(url); The HasPageBeenVisited method determines whether the destination page has any data on it by checking one of its required data fields. (I won't include it here because it is very system-dependent.) VISITED is a string constant containing "?v=1" and gets appended to the url if the destination page has been visited. The reason this logic is within the "Next" and "Previous" button click event methods is because 1) the Validate method is static which doesn't allow it to access non-static data such as the data fields for a particular page, and 2) at the time at which the Validate method runs, either the data has not yet been deserialized from Session state or is not available (different AppDomain?) because anytime I accessed the Session state information from the Validate method, it was always empty.

  In this Issue: Lazar Nikolov, Rudi Grobler, WindowsPhoneGeek, Jesse Liberty, Pete Brown, Jessica Foster, Chris Rouw, Andy Beaulieu, and Colin Eberhardt. Above the Fold: Silverlight: "A Silverlight Resizable TextBlock (and other resizable things)" Colin Eberhardt WP7: "Retrofitting the Trial API" Jessica Foster Shoutouts: Rudi Grobler has a post up that's not Silverlight, but it's cool stuff you may be interested in: WPF Themes now available on NuGet From SilverlightCream.com: Simulating rain in Silverlight Lazar Nikolov has a cool tutorial up at SilverlightShow... Simulating rain. Nice demo near to top, and source code plus a very nice tutorial on the entire process. Making the ApplicationBar bindable Rudi Grobler has a couple new posts up... first this one on making the WP7 AppBar bindable... he's created 2 simple wrappers that make it possible to bind to a method... with source as usual! All about Splash Screens in WP7 – Creating animated Splash Screen WindowsPhoneGeek's latest is about splash screens in WP7, but he goes one better with animated splash screens. Lots of good information including closing points in more of a FAQ-style listing. Testing Network Availability Jesse Liberty's latest is on testing for network availability in your WP7 app. This should be required reading for anyone building a WP7 app, since you never know when the network is going to be there or not. Lighting up on Windows 7 with Native Extensions for Microsoft Silverlight Pete Brown's latest post is about the Native Extensions for Microsoft Silverlight or NESL library. Pete describes what NESL is, a link to the library, installing it, and tons more information. If you wanna know or try NESL... this looks like the place to start. Retrofitting the Trial API Jessica Foster paused on the way to shipping her WP7 app to add in the trial API code. Check out what she went through to complete that task, as she explains the steps and directions she took. Good description, links, and code. WP7 Insights #2: Creating a Splash Screen in WP7 In the 2nd post in his series on WP7 development, Chris Rouw is discussing a WP7 splash screen. He gives some good external links for references then gets right into discussing his code. Air Hockey for Windows Phone 7 Andy Beaulieu shares a tutorial he wrote for the Expression Toolbox site, using the Physics Helper Library and Farseer Physics Engine -- an Air Hockey game for WP7. A Silverlight Resizable TextBlock (and other resizable things) I think Michael Washington had the best comment about Colin Eberhardt's latest outing: "Another WOW example" ... drop this in the pretty darn cool category: an attached behavior that uses a Thumb control within a popup to adorn any UI element to allow the user to resize it!

• Calling Web Services using ADF 11g

  - by James Taylor

  One of the benefits of ADF is that fact that it can use multiple data sources. With SOA playing a big part in today’s IT landscape, applications need to be able to utilise this SOA framework to leverage functionality from multiple systems to provide a composite application. ADF provides functionality to expose web services via the ADF Business Component so if you know how to use Business Components for a database. Configuring ADF for web services is much the same. In this example I use an OSB web service that gets a customer. Create a new Fusion Web Application (ADF) Application and click OK    Provide an Application Name, GetCustomerADF and click Next    From the Project Technologies move Web Services into the Selected box. Accept the defaults and click Finish. Right-click the Model project and select New In the Gallery select Web Services –> Web Service Data Control then click OK. Provide a name GetCustomerDC and give the URL endpoint for the Web Service, then click Next Select the web service operation you want to use for the ADF application. In my example my web service only has one operation. Click Finish Save your work, File –> Save The data control has now been created, the next steps create the UI components. In your application created in step 1 find the ViewController project, right-click and choose New In the Gallery select JSF –> JSF Page Provide a name for the jsp page, GetCustomer, Also ensure that the ‘Create as XML Document (*.jsp) check box is checked. I have selected the page template, Oracle Three Column Layout but you can create a layout of your choice. I only want 2 columns so I delete the last column but right-clicking the right had panel and selecting Delete Drag the fields you require from the web service data control to the left pannel. In my example I only require the Customer ID. When you drag to the panel select Texts –>ADF Input Text w/Label In this example I want to search on a customer based on the ID. So Once I select the ID I want to execute the request. To do this I need a button. Drag the operation object under the fields created in step 15. Select Methods –> ADF Button. You now need to provide the mappings, Choose the ‘Show EI Expression Builder’ Navigate to the bindings, ADFBindings –> bindings –> parametersIterator –> currentRow Click OK Drag and drop the return information I just want the results shown in a form. I want to show all fields Now it is time to test, Right-click the jspx page created in steps 11 – 21 and select Run A browser should start, enter valid values and test

• Performance problems loading XML with SSIS, an alternative way!

  - by AtulThakor

  I recently needed to load several thousand XML files into a SQL database, I created an SSIS package which was created as followed: Using a foreach container to loop through a directory and load each file path into a variable, the “Import XML” dataflow would then load each XML file into a SQL table.       Running this, it took approximately 1 second to load each file which seemed a massive amount of time to parse the XML and load the data, speaking to my colleague Martin Croft, he suggested the use of T-SQL Bulk Insert and OpenRowset, so we adjusted the package as followed:     The same foreach container was used but instead the following SQL command was executed (this is an expression):     "INSERT INTO MyTable(FileDate) SELECT   CAST(bulkcolumn AS XML)     FROM OPENROWSET(         BULK         '" + @[User::CurrentFile]  + "',         SINGLE_BLOB ) AS x"     Using this method we managed to load approximately 20 records per second, much faster…for data loading! For what we wanted to achieve this was perfect but I’ll leave you with the following points when making your own decision on which solution you decide to choose!      Openrowset Method Much faster to get the data into SQL You’ll need to parse or create a view over the XML data to allow the data to be more usable(another post on this!) Not able to apply validation/transformation against the data when loading it The SQL Server service account will need permission to the file No schema validation when loading files SSIS Slower (in our case) Schema validation Allows you to apply transformations/joins to the data Permissions should be less of a problem Data can be loaded into the final form through the package When using a schema validation errors can fail the package (I’ll do another post on this)

• SQL SERVER – Simple Explanation and Puzzle with SOUNDEX Function and DIFFERENCE Function

  - by pinaldave

  Earlier this week I asked a question where I asked how to Swap Values of the column without using CASE Statement. Read here: A Puzzle – Swap Value of Column Without Case Statement,there were more than 50 solutions proposed in the comment. There were many creative solutions. I have mentioned my personal favorite (different ones) here: Solution of Puzzle – Swap Value of Column Without Case Statement. However, I received lots of questions regarding one of the Solution by SIJIN KUMAR V P. He has used the function SOUNDEX in his solution. The request was to explain how SOUNDEX and DIFFERENCE works. Well, there are pretty decent documentations provided over here SOUNDEX function and DIFFERENCE over on MSDN and if I attempt to explain this function I will end up writing the same details which are available on MSDN. Instead of writing theory, we will try to learn this function by using a couple of simple puzzles. You try to solve the puzzles using the MSDN and see if you can learn something very quickly. In simple words - SOUNDEX converts an alphanumeric string to a four-character code to find similar-sounding words or names. The first character of the code is the first character of character_expression and the second through fourth characters of the code are numbers that represent the letters in the expression. Vowels incharacter_expression are ignored unless they are the first letter of the string. DIFFERENCE function returns an integer value. The  integer returned is the number of characters in the SOUNDEX values that are the same. The return value ranges from 0 through 4: 0 indicates weak or no similarity, and 4 indicates strong similarity or the same values. Learning Puzzle 1: Now let us run following four queries and observe its output. SELECT SOUNDEX('SQLAuthority') SdxValue SELECT SOUNDEX('SLTR') SdxValue SELECT SOUNDEX('SaLaTaRa') SdxValue SELECT SOUNDEX('SaLaTaRaM') SdxValue When you look at the result set all the four values are same. The reason for all the values to be same is as for SQL Server SOUNDEX function all the four strings are similarly sounding string. Learning Puzzle 2: Now let us run following five queries and observe its output. SELECT DIFFERENCE (SOUNDEX('SLTR'),SOUNDEX('SQLAuthority')) SELECT DIFFERENCE (SOUNDEX('TH'),SOUNDEX('SQLAuthority')) SELECT DIFFERENCE ('SQLAuthority',SOUNDEX('SQLAuthority')) SELECT DIFFERENCE ('SLTR',SOUNDEX('SQLAuthority')) SELECT DIFFERENCE ('SLTR','SQLAuthority') When you look at the result set you will get the result in the ranges from 1 to 4. Here is how it works if your result is 0 which means absolutely not relevant to each other and if your result is 1 which means the results are relevant to each other. Have you ever used above two functions in your business need or on production server? If yes, would you please leave a comment with use cases. I believe it will be beneficial to everyone.

• Database Mirroring on SQL Server Express Edition

  - by Most Valuable Yak (Rob Volk)

  Like most SQL Server users I'm rather frustrated by Microsoft's insistence on making the really cool features only available in Enterprise Edition.  And it really doesn't help that they changed the licensing for SQL 2012 to be core-based, so now it's like 4 times as expensive!  It almost makes you want to go with Oracle.  That, and a desire to have Larry Ellison do things to your orifices. And since they've introduced Availability Groups, and marked database mirroring as deprecated, you'd think they'd make make mirroring available in all editions.  Alas…they don't…officially anyway.  Thanks to my constant poking around in places I'm not "supposed" to, I've discovered the low-level code that implements database mirroring, and found that it's available in all editions! It turns out that the query processor in all SQL Server editions prepends a simple check before every edition-specific DDL statement: IF CAST(SERVERPROPERTY('Edition') as nvarchar(max)) NOT LIKE '%e%e%e% Edition%' print 'Lame' else print 'Cool' If that statement returns true, it fails. (the print statements are just placeholders)  Go ahead and test it on Standard, Workgroup, and Express editions compared to an Enterprise or Developer edition instance (which support everything). Once again thanks to Argenis Fernandez (b | t) and his awesome sessions on using Sysinternals, I was able to watch the exact process SQL Server performs when setting up a mirror.  Surprisingly, it's not actually implemented in SQL Server!  Some of it is, but that's something of a smokescreen, the real meat of it is simple filesystem primitives. The NTFS filesystem supports links, both hard links and symbolic, so that you can create two entries for the same file in different directories and/or different names.  You can create them using the MKLINK command in a command prompt: mklink /D D:\SkyDrive\Data D:\Data mklink /D D:\SkyDrive\Log D:\Log This creates a symbolic link from my data and log folders to my Skydrive folder.  Any file saved in either location will instantly appear in the other.  And since my Skydrive will be automatically synchronized with the cloud, any changes I make will be copied instantly (depending on my internet bandwidth of course). So what does this have to do with database mirroring?  Well, it seems that the mirroring endpoint that you have to create between mirror and principal servers is really nothing more than a Skydrive link.  Although it doesn't actually use Skydrive, it performs the same function.  So in effect, the following statement: ALTER DATABASE Mir SET PARTNER='TCP://MyOtherServer.domain.com:5022' Is turned into: mklink /D "D:\Data" "\\MyOtherServer.domain.com\5022$" The 5022$ "port" is actually a hidden system directory on the principal and mirror servers. I haven't quite figured out how the log files are included in this, or why you have to SET PARTNER on both principal and mirror servers, except maybe that mklink has to do something special when linking across servers.  I couldn't get the above statement to work correctly, but found that doing mklink to a local Skydrive folder gave me similar functionality. To wrap this up, all you have to do is the following: Install Skydrive on both SQL Servers (principal and mirror) and set the local Skydrive folder (D:\SkyDrive in these examples) On the principal server, run mklink /D on the data and log folders to point to SkyDrive: mklink /D D:\SkyDrive\Data D:\Data On the mirror server, run the complementary linking: mklink /D D:\Data D:\SkyDrive\Data Create your database and make sure the files map to the principal data and log folders (D:\Data and D:\Log) Viola! Your databases are kept in sync on multiple servers! One wrinkle you will encounter is that the mirror server will show the data and log files, but you won't be able to attach them to the mirror SQL instance while they are attached to the principal. I think this is a bug in the Skydrive, but as it turns out that's fine: you can't access a mirror while it's hosted on the principal either.  So you don't quite get automatic failover, but you can attach the files to the mirror if the principal goes offline.  It's also not exactly synchronous, but it's better than nothing, and easier than either replication or log shipping with a lot less latency. I will end this with the obvious "not supported by Microsoft" and "Don't do this in production without an updated resume" spiel that you should by now assume with every one of my blog posts, especially considering the date.

• Three Key Tenets of Optimal Social Collaboration

  - by kellsey.ruppel

  Today's blog post comes to us from John Bruswick! This post is an abridged version of John’s white paper in which he discusses three principals to optimize social collaboration within an enterprise.   By [email protected], Oracle Principal Sales Consultant Effective social collaboration is actionable, deeply contextual and inherently derives its value from business entities outside of itself. How does an organization begin the journey from traditional, siloed collaboration to natural, business entity based social collaboration? Successful enablement of enterprise social collaboration requires that organizations embrace the following tenets and understand that traditional collaborative functionality has inherent limits - it is innovation and integration in accordance with the following tenets that will provide net-new efficiency benefits. Key Tenets of Optimal Social Collaboration Leverage a Ubiquitous Social Fabric - Collaborative activities should be supported through a ubiquitous social fabric, providing a personalized experience, broadcasting key business events and connecting people and business processes.  This supports education of participants working in and around a specific business entity that will benefit from an implicit capture of tacit knowledge and provide continuity between participants.  In the absence of this ubiquitous platform activities can still occur but are essentially siloed causing frequent duplication of effort across similar tasks, with critical tacit knowledge eluding capture. Supply Continuous Context to Support Decision Making and Problem Solving - People generally engage in collaborative behavior to obtain a decision or the resolution for a specific issue.  The time to achieve resolution is referred to as "Solve Time".  Users have traditionally been forced to switch or "alt-tab" between business systems and synthesize their own context across disparate systems and processes.  The constant loss of context forces end users to exert a large amount of effort that could be spent on higher value problem solving. Extend the Collaborative Lifecycle into Back Office - Beyond the solve time from decision making efforts, additional time is expended formalizing the resolution that was generated from collaboration in a system of record.  Extending collaboration to result in the capture of an explicit decision maximizes efficiencies, creating a closed circuit for a particular thread.  This type of structured action may exist today within your organization's customer support system around opening, solving and closing support issues, but generally does not extend to Sales focused collaborative activities. Excelling in the Unstructured Future We will always have to deal with unstructured collaborative processes within our organizations.  Regardless of the participants and nature of the collaborate process, two things are certain – the origination and end points are generally known and relate to a business entity, perhaps a customer, opportunity, order, shipping location, product or otherwise. Imagine the benefits if an organization's key business systems supported a social fabric, provided continuous context and extended the lifecycle around the collaborative decision making to include output into back office systems of record.   The technical hurdle to embracing optimal social collaboration would fall away, leaving the company with an opportunity to focus on and refine how processes were approached.  Time and resources previously required could then be reallocated to focusing on innovation to support competitive differentiation unique to your business. How can you achieve optimal social collaboration? Oracle Social Network enables business users to collaborate with each other using a broad range of collaboration styles and integrates data from a variety of sources and business applications -- allowing you to achieve optimal social collaboration. Looking to learn more? Read John's white paper, where he discusses in further detail the three principals to optimize social collaboration within an enterprise.

• Finding the XPath with the node name

  - by julien.schneider(at)oracle.com

  A function that i find missing is to get the Xpath expression of a node. For example, suppose i only know the node name <theNode>, i'd like to get its complete path /Where/is/theNode.   Using this rather simple Xquery you can easily get the path to your node. declare namespace orcl = "http://www.oracle.com/weblogic_soa_and_more"; declare function orcl:findXpath($path as element()*) as xs:string { if(local-name($path/..)='') then local-name($path) else concat(orcl:findXpath($path/..),'/',local-name($path)) }; declare function orcl:PathFinder($inputRecord as element(), $path as element()) as element(*) { { for $index in $inputRecord//*[local-name()=$path/text()] return orcl:findXpath($index) } }; declare variable $inputRecord as element() external; declare variable $path as element() external; orcl:PathFinder($inputRecord, $path)   With a path         <myNode>nodeName</myNode>  and a message         <node1><node2><nodeName>test</nodeName></node2></node1>  the result will be         node1/node2/nodeName   This is particularly useful when you use the Validate action of OSB because Validate only returns the xml node which is in error and not the full location itself. The following OSB project reuses this Xquery to reformat the result of the Validate Action. Just send an invalid xml like <myElem http://blogs.oracle.com/weblogic_soa_and_more"http://blogs.oracle.com/weblogic_soa_and_more">      <mySubElem>      </mySubElem></myElem>   you'll get as nice <MessageIsNotValid> <ErrorDetail  nbr="1"> <dataElementhPath>Body/myElem/mySubElem</dataElementhPath> <message> Expected element 'Subelem1@http://blogs.oracle.com/weblogic_soa_and_more' before the end of the content in element mySubElem@http://blogs.oracle.com/weblogic_soa_and_more </message> </ErrorDetail> </MessageIsNotValid>   Download the OSB project : sbconfig_xpath.jar   Enjoy.

• SQL Saturday #162 Cambridge

  - by Most Valuable Yak (Rob Volk)

  Despite the efforts of American Airlines, this past weekend I attended the first SQL Saturday in the UK!  Hosted by the SQLCambs Chapter of PASS and organized by Mark (b|t) & Lorraine Broadbent, ably assisted by John Martin (b|t), Mark Pryce-Maher (b|t) and other folks whose names I've unfortunately forgotten, it was held at the Crowne Plaza Hotel, which is completely surrounded by Cambridge University. On Friday, they presented 3 pre-conference sessions given by the brilliant American Cloud & DBA Guru, Buck Woody (b|t), the brilliant Danish SQL Server Internals Guru, Mark Rasmussen (b|t), and the brilliant Scottish Business Intelligence Guru and recent Outstanding Pass Volunteer, Jen Stirrup (b|t).  While I would have loved to attend any of their pre-cons (having seen them present several times already), finances and American Airlines ultimately made that impossible.  But not to worry, I caught up with them during the regular sessions and at the speaker dinner.  And I got back the money they all owed me.  (Actually I owed Mark some money) The schedule was jam-packed even with only 4 tracks, there were 8 regular slots, a lunch session for sponsor presentations, and a 15 minute keynote given by Buck Woody, who besides giving an excellent history of SQL Server at Microsoft (and before), also explained the source of the "unknown contact" image that appears in Outlook.  Hint: it's not Buck himself. Amazingly, and against all better judgment, I even got to present at SQL Saturday 162!  I did a 5 minute Lightning Talk on Regular Expressions in SSMS.  I then did a regular 50 minute session on Constraints.  You can download the content for the regular session at that link, and for the regular expression presentation here. I had a great time and had a great audience for both of my sessions.  You would never have guessed this was the first event for the organizers, everything went very smoothly, especially for the number of attendees and the relative smallness of the space.  The event sponsors also deserve a lot of credit for making themselves fit in a small area and for staying through the entire event until the giveaways at the very end. Overall this was one of the best SQL Saturdays I've ever attended and I have to congratulate Mark B, Lorraine, John, Mark P-M, and all the volunteers and speakers for making this an astoundingly hard act to follow!  Well done!

• Countdown of Top 10 Reasons to Never Ever Use a Pie Chart

  - by Tony Wolfram

    Pie charts are evil. They represent much of what is wrong with the poor design of many websites and software applications. They're also innefective, misleading, and innacurate. Using a pie chart as your graph of choice to visually display important statistics and information demonstrates either a lack of knowledge, laziness, or poor design skills. Figure 1: A floating, tilted, 3D pie chart with shadow trying (poorly)to show usage statistics within a graphics application.   Of course, pie charts in and of themselves are not evil. This blog is really about designers making poor decisions for all the wrong reasons. In order for a pie chart to appear on a web page, somebody chose it over the other alternatives, and probably thought they were doing the right thing. They weren't. Using a pie chart is almost always a bad design decision. Figure 2: Pie Chart from an Oracle Reports User Guide   A pie chart does not do the job of effectively displaying information in an elegant visual form.  Being circular, they use up too much space while not allowing their labels to line up. Bar charts, line charts, and tables do a much better job. Expert designers, statisticians, and business analysts have documented their many failings, and strongly urge software and report designers not to use them. It's obvious to them that the pie chart has too many inherent defects to ever be used effectively. Figure 3: Demonstration of how comparing data between multiple pie charts is difficult.   Yet pie charts are still used frequently in today's software applications, financial reports, and websites, often on the opening page as a symbol of how the data inside is represented. In an attempt to get a flashy colorful graphic to break up boring text, designers will often settle for a pie chart that looks like pac man, a colored spinning wheel, or a 3D floating alien space ship.     Figure 4: Best use of a pie chart I've found yet.   Why is the pie chart so popular? Through its constant use and iconic representation as the classic chart, the idea persists that it must be a good choice, since everyone else is still using it. Like a virus or an urban legend, no amount of vaccine or debunking will slow down the use of pie charts, which seem to be resistant to logic and common sense. Even the new iPad from Apple showcases the pie chart as one of its options.     Figure 5: Screen shot of new iPad showcasing pie charts. Regardless of the futility in trying to rid the planet of this often used poor design choice, I now present to you my top 10 reasons why you should never, ever user a pie chart again.    Number 10 - Pie Charts Just Don't Work When Comparing Data Number 9 - You Have A Better Option: The Sorted Horizontal Bar Chart Number 8 - The Pie Chart is Always Round Number 7 - Some Genius Will Make It 3D Number 6 - Legends and Labels are Hard to Align and Read Number 5 - Nobody Has Ever Made a Critical Decision Using a Pie Chart Number 4 - It Doesn't Scale Well to More Than 2 Items Number 3 - A Pie Chart Causes Distortions and Errors Number 2 - Everyone Else Uses Them: Debunking the "Urban Legend" of Pie Charts Number 1 - Pie Charts Make You Look Stupid and Lazy

• 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.

• DotNetNuke 7.0 Only Weeks Away!

  - by sbwalker

  The software industry moves at a lightning pace, and it is only through constant focus and continuous investment that a software product can remain both stable and relevant over the long term. As we approach the 10 Year Anniversary of the DotNetNuke platform, it seems only fitting that we are on the verge of announcing yet another significant product milestone. DotNetNuke 7.0 is just around the corner and represents a bold step forward for our Content Management Platform, including substantial business productivity enhancements, investments in web platform relevance, and a significant overhaul and modernization of the user interface and user experience. It has been five months since I posted the announcement that the next major version of the platform was going to be DotNetNuke 7.0.  This announcement created tremendous excitement and anticipation in the DotNetNuke community, as major version increments have always been utilized as an opportunity  to introduce revolutionary new product features and capabilities. After months of intense product development, the finish line is finally in sight. With that, I am pleased to announce that we released a Release Candidate (RC) of DotNetNuke 7.0 yesterday. You can download the RC from our project page on Codeplex. A Release Candidate represents a software version which is very near to “release” quality. So although we will not be officially endorsing the RC for production use, or providing an official upgrade path, it does represent a significant milestone in our software development efforts ( if you are looking for a more detailed explanation of our software release terminology, I would encourage you to read the blog written by Co-Founder, Joe Brinkman titled "What's In A Name?" ). Modernizing a software platform does have its share of challenges from a backward compatibility perspective and, as usual, we are taking great care in ensuring a seamless upgrade path for our customers. In order to remain relevant and progressive, you need to be aware that DotNetNuke 7.0 has adopted a new set of baseline infrastructure requirements including ASP.NET 4.0.  As a result we are encouraging all major stakeholders in the ecosystem ( module developers, designers, partners, customers, etc... ) to take the opportunity to install the RC in their own local environments. This is the last opportunity to let us know about any final issues which may need to be addressed prior to final release. Mark your calendars now… the expected public release date (RTM) for DotNetNuke 7.0 will be Wednesday, November 28th. On a side note, we expect to release a 6.2.5 Maintenance version today. This release contains some high priority product quality improvements as well as security patches for some vulnerabilities reported through our standard ecosystem channels. As a result we will be encouraging all of our customers to upgrade to the 6.2.5 release as soon as it is available. I hope everyone is as excited as I am about the upcoming DotNetNuke 7.0 release. Please take the opportunity over the next week to put the new platform through its paces. Remember, only through our collective efforts can we ensure that this release has the greatest market impact of any DotNetNuke release to date.

• Designing Mobile SMS text advertising system

  - by Ramraj Edagutti

  Currently, I am working on a product where we have an SMS text advertising system, and using this, we setup advertising campaigns for clients, and later these campaigns are sent to the end users. This is very similar to Google Adwords, but targeted to Mobile users via SMS. Just to give an overview of the system Each Campaign is mapped to an advertiser Campaign has start date and end date Campaign has a filter condition(s) or query to select the target user base from our database (to whom we send Campaigns) Target user base can be fixed, for e.g send campaign to 10000 users Target user base can also be dynamic based on query condition, for e.g send campaign to users who are active and from a particular state, district, town etc. (this way user base will be keep changing on daily basis) Campaign can have multiple campaign messages Each campaign message has start date and end date Each campaign message can have multiple message texts for different locales, for e.g English,Hindi,Telugu etc After creating an advertisement campaign, we run daily night job to provision the target user base for that a particular campaign in a separate table, and another daily job runs on morning times and checks provisioned table for campaigns and targeted users and sends the campaign to users via SMS. Problem is, current UI for creating advertising campaigns is designed in a very technical manner, I mean, normal user or business owner or clients can not use the UI to create a campaign. Below are reasons why the UI is very technical in nature Filter condition(s) or query input filed, takes user ids or mobile numbers or SQL queries. Most of times or almost every time, we use big SQL queries So we end up storing SQL queries in a database for a campaign, later we use this SQL query to fetch targeted user base. For scheduling these campaigns, we have input filed on UI which takes quartz cron expression(s) ( for e.g. send campaign on "0 0 9 1-10 MAR 2012" ), again very technical in nature Normal user or business owner, can not use the UI for creating campaigns for reasons mentioned above, Currently, we ourself (developers) helping clients to setup/create campaigns. we are trying to re-design the UI to make it more user friendly so that any user can go to UI and create an advertisement campaign by himself. I am thinking of re-designing the current UI similar to Google Adwords interface, especially for selecting target users based on user geography like country, state, city etc. I also need to select users based user subscription(s), which might make system even more complex. And also, for campaign scheduling, I am thinking of using weekdays with hours. For example, I will shows Monday to Sunday on UI, and user can select the from hours, to hours etc. Any better ideas or suggestion on how to design UI in very user friendly manner and what design should be followed on server side code (we write backend code on java/jpa/spring/quartz)? And I am looking for ideas or design patterns on how to build SQL queries (using JPA/Hinernate) programmatically on server side, based on varies conditions like based on country, state, town, village, and user subscriptions.

• SQL Prompt Easter Egg

  - by Johnm

  Having Red Gate's SQL Prompt installed with SQL Server Management Studio has saved me many headaches over the years of its use. It is extremely nice to type in a table name and see not only the column names, but also their data types and identification of primary keys. Another cool feature is the built-in short cut scripts that are included toward the bottom of the suggestion box. An example of these short cut scripts would be to type in the letters  cv and then hit enter and the following template for CREATE VIEW will appear: CREATE VIEW --WITH ENCRYPTION, SCHEMABINDING, VIEW_METADATA AS     SELECT /* query specification */ -- WITH CHECK OPTION GO These scripts are great, and on occasion rather humorous. Recently, I was writing an UPDATE statement that would update a derived and aliased set of data in . An example of such a statement is as follows: UPDATE y SET a.[FieldA] = b.[FieldB] FROM     (         SELECT             a.[FieldA]             ,b.[FieldB]         FROM             [MyTableA] a             INNER JOIN [MyTableB] b                 ON a.[PKA] = b.[PKB]     ) y; Upon typing the UPDATE y portion I hit enter and the expression "A A A A R G H !" appeared resulting in an unexpected burst of laughter. With a dash of curiosity and a pinch of research I discovered that at the bottom of the SQL Prompt suggestion box resides a short cut script called "yell", which is described as "Vent your frustration". Another humorous short cut script is "neo", which is described as "-- I know Kung-Fu". All is required for these to activate is to type the first letter and hit enter. I wonder if there are any undocumented ones?

• Default Parameters vs Method Overloading

  - by João Angelo

  With default parameters introduced in C# 4.0 one might be tempted to abandon the old approach of providing method overloads to simulate default parameters. However, you must take in consideration that both techniques are not interchangeable since they show different behaviors in certain scenarios. For me the most relevant difference is that default parameters are a compile time feature while method overloading is a runtime feature. To illustrate these concepts let’s take a look at a complete, although a bit long, example. What you need to retain from the example is that static method Foo uses method overloading while static method Bar uses C# 4.0 default parameters. static void CreateCallerAssembly(string name) { // Caller class - Invokes Example.Foo() and Example.Bar() string callerCode = String.Concat( "using System;", "public class Caller", "{", " public void Print()", " {", " Console.WriteLine(Example.Foo());", " Console.WriteLine(Example.Bar());", " }", "}"); var parameters = new CompilerParameters(new[] { "system.dll", "Common.dll" }, name); new CSharpCodeProvider().CompileAssemblyFromSource(parameters, callerCode); } static void Main() { // Example class - Foo uses overloading while Bar uses C# 4.0 default parameters string exampleCode = String.Concat( "using System;", "public class Example", "{{", " public static string Foo() {{ return Foo(\"{0}\"); }}", " public static string Foo(string key) {{ return \"FOO-\" + key; }}", " public static string Bar(string key = \"{0}\") {{ return \"BAR-\" + key; }}", "}}"); var compiler = new CSharpCodeProvider(); var parameters = new CompilerParameters(new[] { "system.dll" }, "Common.dll"); // Build Common.dll with default value of "V1" compiler.CompileAssemblyFromSource(parameters, String.Format(exampleCode, "V1")); // Caller1 built against Common.dll that uses a default of "V1" CreateCallerAssembly("Caller1.dll"); // Rebuild Common.dll with default value of "V2" compiler.CompileAssemblyFromSource(parameters, String.Format(exampleCode, "V2")); // Caller2 built against Common.dll that uses a default of "V2" CreateCallerAssembly("Caller2.dll"); dynamic caller1 = Assembly.LoadFrom("Caller1.dll").CreateInstance("Caller"); dynamic caller2 = Assembly.LoadFrom("Caller2.dll").CreateInstance("Caller"); Console.WriteLine("Caller1.dll:"); caller1.Print(); Console.WriteLine("Caller2.dll:"); caller2.Print(); } And if you run this code you will get the following output: // Caller1.dll: // FOO-V2 // BAR-V1 // Caller2.dll: // FOO-V2 // BAR-V2 You see that even though Caller1.dll runs against the current Common.dll assembly where method Bar defines a default value of “V2″ the output show us the default value defined at the time Caller1.dll compiled against the first version of Common.dll. This happens because the compiler will copy the current default value to each method call, much in the same way a constant value (const keyword) is copied to a calling assembly and changes to it’s value will only be reflected if you rebuild the calling assembly again. The use of default parameters is also discouraged by Microsoft in public API’s as stated in (CA1026: Default parameters should not be used) code analysis rule.

• Export all SSIS packages from msdb using Powershell

  - by jamiet

  Have you ever wanted to dump all the SSIS packages stored in msdb out to files? Of course you have, who wouldn’t? Right? Well, at least one person does because this was the subject of a thread (save all ssis packages to file) on the SSIS forum earlier today. Some of you may have already figured out a way of doing this but for those that haven’t here is a nifty little script that will do it for you and it uses our favourite jack-of-all tools … Powershell!! Imagine I have the following package folder structure on my Integration Services server (i.e. in [msdb]): There are two packages in there called “20110111 Chaining Expression components” & “Package”, I want to export those two packages into a folder structure that mirrors that in [msdb]. Here is the Powershell script that will do that:Param($SQLInstance = "localhost") #####Add all the SQL goodies (including Invoke-Sqlcmd)##### add-pssnapin sqlserverprovidersnapin100 -ErrorAction SilentlyContinue add-pssnapin sqlservercmdletsnapin100 -ErrorAction SilentlyContinue cls $Packages = Invoke-Sqlcmd -MaxCharLength 10000000 -ServerInstance $SQLInstance -Query "WITH cte AS ( SELECT cast(foldername as varchar(max)) as folderpath, folderid FROM msdb..sysssispackagefolders WHERE parentfolderid = '00000000-0000-0000-0000-000000000000' UNION ALL SELECT cast(c.folderpath + '\' + f.foldername as varchar(max)), f.folderid FROM msdb..sysssispackagefolders f INNER JOIN cte c ON c.folderid = f.parentfolderid ) SELECT c.folderpath,p.name,CAST(CAST(packagedata AS VARBINARY(MAX)) AS VARCHAR(MAX)) as pkg FROM cte c INNER JOIN msdb..sysssispackages p ON c.folderid = p.folderid WHERE c.folderpath NOT LIKE 'Data Collector%'" Foreach ($pkg in $Packages) { $pkgName = $Pkg.name $folderPath = $Pkg.folderpath $fullfolderPath = "c:\temp\$folderPath\" if(!(test-path -path $fullfolderPath)) { mkdir $fullfolderPath | Out-Null } $pkg.pkg | Out-File -Force -encoding ascii -FilePath "$fullfolderPath\$pkgName.dtsx" } To run it simply change the “localhost” parameter of the server you want to connect to either by editing the script or passing it in when the script is executed. It will create the folder structure in C:\Temp (which you can also easily change if you so wish – just edit the script accordingly). Here’s the folder structure that it created for me: Notice how it is a mirror of the folder structure in [msdb]. Hope this is useful! @Jamiet UPDATE: THis post prompted Chad Miller to write a post describing his Powershell add-in that utilises a SSIS API to do exporting of packages. Go take a read here: http://sev17.com/2011/02/importing-and-exporting-ssis-packages-using-powershell/

• From DBA to Data Analyst

  - by Denise McInerney

  Cross posted from the PASS Blog There is a lot changing in the data professional’s world these days. More data is being produced and stored. More enterprises are trying to use that data to improve their products and services and understand their customers better. More data platforms and tools seem to be crowding the market. For a traditional DBA this can be a confusing and perhaps unsettling time. It’s also a time that offers great opportunity for career growth. I speak from personal experience. We sometimes refer to the “accidental DBA”, the person who finds herself suddenly responsible for managing the database because she has some other technical skills. While it was not accidental, six months ago I was unexpectedly offered a chance to transition out of my DBA role and become a data analyst. I have since come to view this offer as a gift, though at the time I wasn’t quite sure what to do with it. Throughout my DBA career I’ve gotten support from my PASS friends and colleagues and they were the first ones I turned to for counsel about this new situation. Everyone was encouraging and I received two pieces of valuable advice: first, leverage what I already know about data and second, work to understand the business’ needs. Bringing the power of data to bear to solve business problems is really the heart of the job. The challenge is figuring out how to do that. PASS had been the source of much of my technical training as a DBA, so I naturally started there to begin my Business Intelligence education. Once again the Virtual Chapter webinars, local chapter meetings and SQL Saturdays have been invaluable. I work in a large company where we are fortunate to have some very talented data scientists and analysts. These colleagues have been generous with their time and advice. I also took a statistics class through Coursera where I got a refresher in statistics and an introduction to the R programming language. And that’s not the end of the free resources available to someone wanting to acquire new skills. There are many knowledgeable Business Intelligence and Analytics professionals who teach through their blogs. Every day I can learn something new from one of these experts. Sometimes we plan our next career move and sometimes it just happens. Either way a database professional who follows industry developments and acquires new skills will be better prepared when change comes. Take the opportunity to learn something about the changing data landscape and attend a Business Intelligence, Business Analytics or Big Data Virtual Chapter meeting. And if you are moving into this new world of data consider attending the PASS Business Analytics Conference in April where you can meet and learn from those who are already on that road. It’s been said that “the only thing constant is change.” That’s never been more true for the data professional than it is today. But if you are someone who loves data and grasps its potential you are in the right place at the right time.

• What do you think of the EntLib 5.0 configuration tool?

  Hello again! Its been a while, I know. Ive been busy over the last few months with several projects, some of them software related, and one of them human my son Jesse was born on 26 February 2010. Fun times! Meanwhile, back in Redmond, the p&p team has been busy working on Enterprise Library 5.0 see Grigoris announcement for details on the beta. Theres a ton of new stuff in this release, but theres one big new feature that hasnt received a lot of attention that Im keen to hear your perspectives on. The change is the biggest overhaul to the configuration tool since Enterprise Library was launched. If you havent yet grabbed the EntLib 5.0 beta, heres a before and after shot of the config tool: Enterprise Library 4.1 config tool Enterprise Library 5.0 (beta 1) config tool The tool has been rebuilt from the ground up in response to some feedback and usability studies from the previous version of the tool. But is this a step in the right direction? Id love to hear what you think. If youve downloaded EntLib 5.0 and tried out the tool, please share your thoughts on: First impressions. Is the tool easy to understand? Easy to find what youre looking for? Easy to read existing configuration? Pretty? Ease of use for real life tasks. Rather than make up your own tasks, here are a few sample scenarios you might want to try: Configure the data access block with a SQL Server connection called Audit that points to a database called Audit on a server called DB Configure the logging block so that any log entries in the Audit category are written to both the Event Log and the Audit database (see above) Configure the validation block with a ruleset called Email Address that uses an appropriate regular expression for e-mail addresses Configure the policy injection block such that any calls to classes in the MyCompany.Security namespace are logged before and after the call using the Audit category (see above) Comparison with the old config tool. What do you like better in the new tool? What did you like better in the old tool? How do you rate your level of expertise using the old tool? Keep in mind that I no longer work in the p&p team, so I cant say how any of this feedback will be used (although Im sure the team is listening!). However since Ive invested so much time in Enterprise Library, both in leading the team and using the product on real projects Im very interested to hear what you all think of the tools new direction.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.

• ArchBeat Link-o-Rama for November 8, 2012

  - by Bob Rhubart

  Webcast: Meeting Customer Expectations in the New Age of Retail Keep your eye on this live webcast as Sanjeev Sharma (Principal Product Director, Oracle Exalogic), Kelly Goetsch (Senior Principal Product Manager, Oracle Commerce), and Dan Conway (Senior Product Manager, Oracle Retail) offer real-world examples of business value derived by running customer-facing applications on Oracle Engineered Systems. Live, Thursday Nov 8, 10am PT/ 1pm ET. Solving Big Problems in Our 21st Century Information Society | Irving Wladawsky-Berger "I believe that the kind of extensive collaboration between the private sector, academia and government represented by the Internet revolution will be the way we will generally tackle big problems in the 21st century. Just as with the Internet, governments have a major role to play as the catalyst for many of the big projects that the private sector will then take forward and exploit. The need for high bandwidth, robust national broadband infrastructures is but one such example." — Irving Wladawsky-Berger SOA Still Not Dead: Ratification of Governance Standard Highlights SOA’s Continued Relevance So just about the time I dig into Google Trends to learn that the conversation about governance peaked in 2004, along comes all this InfoQ article by Richard Seroter. And of course you've already listened to the OTN Archbeat Podcast about governance, right? Right? Implications of Java 6 End of Public Updates for Oracle E-Business Suite Users | Steven Chan The short version is: "Nothing will change for EBS users after February 2013." According to Steven Chan, "EBS users will continue to receive critical bug fixes and security fixes as well as general maintenance for Java SE 6." You'll find additional information on Steven's blog. ADF Mobile Custom Javascript – iFrame Injection | John Brunswick The ADF Mobile Framework provides a range of out of the box components to add within your AMX pages, according to John Brunswick. But what happens when "an out of the box component does not directly fulfill your development need? What options are available to extend your application interface?" John has an answer. How Data and BPM are married to get the right information to the right people at the right time | Leon Smiers "Business Process Management…supports a large group of stakeholders within an organization, all with different needs," says Oracle ACE Leon Smiers. "End-to-end processes typically run across departments, stakeholders and applications, and can often have a long life-span. So how do organizations provide all stakeholders with the information they need?" Leon provides answers in this post. Thought for the Day "(When) asking skilled architects…what they do when confronted with highly complex problems…(they) would most likely answer, 'Just use Common Sense.' (A) better expression than 'common sense' is 'contextual sense' — a knowledge of what is reasonable within a given content. Practicing architects through eduction, experience and examples accumulate a considerable body of contextual sense by the time they're entrusted with solving a system-level problem…" — Eberhardt Rechtin (January 16, 1926 – April 14, 2006) Source: SoftwareQuotes.com
