• Alert: It is No Longer 1982, So Why is CRM Still There?

  - by Mike Stiles

  Hot off the heels of Oracle’s recent LinkedIn integration announcement and Oracle Marketing Cloud Interact 2014, the Oracle Social Cloud is preparing for another big event, the CRM Evolution conference and exhibition in NYC. The role of social channels in customer engagement continues to grow, and social customer engagement will be a significant theme at the conference. According to Paul Greenberg, CRM Evolution Conference Chair, author, and Managing Principal at The 56 Group, social channels have become so pervasive that there is no longer a clear reason to make a distinction between “social CRM” and traditional CRM systems. Why not? Because social is a communication hub every bit as vital and used as the phone or email. What makes social different is that if you think of it as a phone, it’s a party line. That means customer interactions are far from secret, and social connections are listening in by the hundreds, hearing whether their friend is having a positive or negative experience with your brand. According to a Mention.com study, 76% of brand mentions are neutral, neither positive nor negative. These mentions fail to get much notice. So think what that means about the remaining 24% of mentions. They’re standing out, because a verdict, about you, is being rendered in them, usually with emotion. Suddenly, where the R of CRM has been lip service and somewhat expendable in the past, “relationship” takes on new meaning, seriousness, and urgency. Remarkably, legions of brands still approach CRM as if it were 1982. Today, brands must provide customer experiences the customer actually likes (how dare they expect such things). They must intimately know not only their customers, but each customer, because technology now makes personalized experiences possible. That’s why the Oracle Social Cloud has been so mission-oriented about seamlessly integrating social with sales, marketing and customer service interactions so the enterprise can have an actionable 360-degree view of the customer. It’s the key to that customer-centricity we hear so much about these days. If you’re attending CRM Evolution, Chris Moody, Director of Product Marketing for the Oracle Marketing Cloud, will show you how unified customer experiences and enhanced customer centricity will help you attract and keep ideal customers and brand advocates (“The Pursuit of Customer-Centricity” Aug 19 at 2:45p ET) And Meg Bear, Group Vice President for the Oracle Social Cloud, will sit on a panel talking about “terms of engagement” and the ways tech can now enhance your interactions with customers (Aug 20 at 10a ET). If you can’t be there, we’ll be doing our live-tweeting thing from the @oraclesocial handle, so make sure you’re a faithful follower. You’ll notice NOBODY is writing about the wisdom of “company-centricity.” Now is the time to bring your customer relationship management into the socially connected age. @mikestilesPhoto: Sue Pizarro, freeimages.com

• Why do I always think I know much less than others? [closed]

  - by John Kenedy

  I have been in programming since primary 6. Since the time DOS comes, I have been doing programming in quickbasic 4.5, then to VB 6, then to C#. In between I also do programming in C++. But every time I open Stack Overflow and trying to help others answering their problems, it seems that I know nothing. I feel that I am so stupid even I have been in programming for so long. I would shock reading all the questions and unable to find any clue. Is technology moving too fast that left out me? I feel that technology changes too fast and I can't keep up, when I know ASP.NET web form, MVC is out, when I know MVC, android/iphone/HTML5 app is popular. It seems that I am chasing something and never reach 'it'. I don't know whether this is correct place for me to talk about this. I just wish to listen to opinion like you, how do you think technology should grow instead of recreating language, adding bug here and there to let programmer figure it out, while big company share the solution among themselves. This is exactly how I feel. The simple example is how do you think why doesn't Dictionary<> in .NET provide iterating the object using index? Why must we use Key or GetEnumerator(). Developer has to google and read wasted hour of hour of time to find pieces of hack code to use reflection to achieve reading from index. Where developer will keep it as collection and valuable code. HOwever when times come, everything changes again, developer has to find answer for new silly problems again! Yes, I really hate it! I hate how many big companies are playing with the developer by cutting a big picture into small puzzle and messing it up and asking developer to place it together themselves. As if they are creating problems for us to solve it, so we are unable to grow upfront, we are being manipulated by those silly problems they have created. Another sample would how difficult to collect Cookies from CookieContainer without passing the URL, yes without the URL and I WANT to get all cookie in the cookiecontainer without knowing the URL, I want to iterate all. Why does micros0ft have to limit me from doing that?

• Your Cinnamon Roll & Morning Coffee: Powered by Oracle Enterprise Manager

  - by Ruma Sanyal

  1024x768 Truth be told, as I was getting my morning coffee today, I was pondering the recent election results more than Oracle [there, I said it]. But then an email from Glen Hawkins from the Enterprise Management team hit my Inbox and I started viewing this video. It was about the world’s largest convenience store chain, 7-Eleven, focusing on creating the best Digital Guest Experience (DGE) for their customers. Turns out that Oracle Enterprise Manager (OEM) powers 7-Eleven’s DGE Middleware Platform as a Service solution that consists of Oracle SOA Suite, Exalogic, and Exadata. “We need to present a consistent view of 7-Eleven across all our endpoints: 10,000 stores & various digital entities like our websites and apps”, said Ronald Clanton, the DGE Program Director for 7-Eleven. As 7-Eleven was rolling out a loyalty program with mobile support across multiple geos, it had many complex business & technical requirements, including supporting a wide variety of different apps, 10M guests in NA alone, ability to support high speed transactions, and very aggressive timelines. A key requirement was shortening the cycle for provisioning new environments. Whereas with other vendors this would take a few weeks, Oracle consulting showed them how with OEM provisioning new environments would take half a day, which was quite impressive. 7-Eleven has started to roll out this new program and are delighted to report that some provisioning cycles are as low as 10 minutes which includes provisioning the full Oracle SOA suite, Exalogic and more. They are delighted with OEM’s reporting capabilities and customization thereof. Watch the video to see for yourself.

• Are closures with side-effects considered "functional style"?

  - by Giorgio

  Many modern programming languages support some concept of closure, i.e. of a piece of code (a block or a function) that Can be treated as a value, and therefore stored in a variable, passed around to different parts of the code, be defined in one part of a program and invoked in a totally different part of the same program. Can capture variables from the context in which it is defined, and access them when it is later invoked (possibly in a totally different context). Here is an example of a closure written in Scala: def filterList(xs: List[Int], lowerBound: Int): List[Int] = xs.filter(x => x >= lowerBound) The function literal x => x >= lowerBound contains the free variable lowerBound, which is closed (bound) by the argument of the function filterList that has the same name. The closure is passed to the library method filter, which can invoke it repeatedly as a normal function. I have been reading a lot of questions and answers on this site and, as far as I understand, the term closure is often automatically associated with functional programming and functional programming style. The definition of function programming on wikipedia reads: In computer science, functional programming is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids state and mutable data. It emphasizes the application of functions, in contrast to the imperative programming style, which emphasizes changes in state. and further on [...] in functional code, the output value of a function depends only on the arguments that are input to the function [...]. Eliminating side effects can make it much easier to understand and predict the behavior of a program, which is one of the key motivations for the development of functional programming. On the other hand, many closure constructs provided by programming languages allow a closure to capture non-local variables and change them when the closure is invoked, thus producing a side effect on the environment in which they were defined. In this case, closures implement the first idea of functional programming (functions are first-class entities that can be moved around like other values) but neglect the second idea (avoiding side-effects). Is this use of closures with side effects considered functional style or are closures considered a more general construct that can be used both for a functional and a non-functional programming style? Is there any literature on this topic? IMPORTANT NOTE I am not questioning the usefulness of side-effects or of having closures with side effects. Also, I am not interested in a discussion about the advantages / disadvantages of closures with or without side effects. I am only interested to know if using such closures is still considered functional style by the proponent of functional programming or if, on the contrary, their use is discouraged when using a functional style.

• Independent Research on 1500 Companies Reveals Challenges in Performance Visibility – Part 1

  - by ndwyouell

  At the end of May I was joined by Professor Andy Neely of Cambridge University on a webinar, with an audience of over 700, to discuss the results of this extensive study which covered 13 countries and nearly every commercial and industrial sector.  What stunned both of us was not so much the number listening but the 100 questions they asked in just 1 hour.  This certainly represents a record in my experience and for those that organized the webinar. So what was all the fuss about?  Well, to begin with this was a pretty big sample and it represented organizations with over $100m sales across the USA, Europe, Africa and the Middle East. It also delivered some pretty interesting results across a wide range of EPM subjects such as profitability, planning and reporting.  Let’s look at some of those findings. We kicked off with profitability, one of the key factors in driving performance, or that is what you would think, but in fact 82% of our respondents said they did not have complete visibility into the profitability of their organization. 91% of these went further to say that, not surprisingly, this lack of knowledge into the profitability has implications with over half citing 3 or more implications.  Implications cited included misallocated resources, revenue opportunities not maximized, erroneous decisions made and impaired financial performance.  Quite a list of implications, especially given the difficult economic circumstances many organizations are operating in at this time. So why is this?  Well other results in the study point to some of the potential reasons.  Firstly 59% of respondents that use spreadsheets use them for monitoring profitability and 93% of all managers responding to the study use spreadsheets to gather and analyze information.  This is an enormous proportion given the problems with using spreadsheets based performance management systems that have been widely talked about for many years.  For profitability analysis this is particularly important when you consider the typical requirement will be to allocate cost and revenue across 6+ dimensions based on many different allocation methods.  Not something that can be done easily in spreadsheets plus it gets to be a nightmare once you want to change allocations, run different scenarios and then change the basis of your planning and budgeting! It is no wonder so many organizations have challenges in performance visibility. My next blog will look at the fragmented nature of many organizations’ planning.  In the meantime if you want to read the complete report on the research go to: http://www.oracle.com/webapps/dialogue/ns/dlgwelcome.jsp?p_ext=Y&p_dlg_id=10077790&src=7038701&Act=29

• TransportWithMessageCredential & Service Bus – Introduction

  - by Michael Stephenson

  Recently we have been working on a project using the Windows Azure Service Bus to expose line of business applications. One of the topics we discussed a lot was around the security aspects of the solution. Most of the samples you see for Windows Azure Service Bus often use the shared secret with the Access Control Service to protect the service bus endpoint but one of the problems we found was that with this scenario any claims resulting from credentials supplied by the client are not passed through to the service listening to the service bus endpoint. As an example of this we originally were hoping that we could give two different clients their own shared secret key and the issuer for each would indicate which client it was. If the claims had flown to the listening service then we could check that the message sent by client one was a type they are allowed to send. Unfortunately this claim isn't flown to the listening service so we were unable to implement this scenario. We had also seen samples that talk about changing the relayClientAuthenticationType attribute would allow you to authenticate the client within the service itself rather than with ACS. While this was interesting it wasn't exactly what we wanted. By removing the step where access to the Relay endpoint is protected by authentication against ACS it means that anyone could send messages via the service bus to the on-premise listening service which would then authenticate clients. In our scenario we certainly didn't want to allow clients to skip the ACS authentication step because this could open up two attack opportunities for an attacker. The first of these would allow an attacker to send messages through to our on-premise servers and potentially cause a denial of service situation. The second case would be with the same kind of attack by running lots of messages through service bus which were then rejected the attacker would be causing us to incur charges per message on our Windows Azure account. The correct way to implement our desired scenario is to combine one of the common options for authenticating against ACS so the service bus endpoint cannot be accessed by an unauthenticated caller with the normal WCF security features using the TransportWithMessageCredential security option. Looking around I could not find any guidance on how to implement this correctly so on the back of setting this up I decided to write a couple of articles to walk through a couple of the common scenarios you may be interested in. These are available on the following links: Walkthrough - Combining shared secret and username token Walkthrough – Combining shared secret and certificates

• My First 5K, the recap.

  - by Chris Williams

  It was a nice day to be outside (and trust me, those aren't words you'll hear from me often.) I got to the site around 7:45, hit the pre-reg table and got my number along with a goody bag full of coupons for racing gear, a water bottle and a tshirt. Oh and a map. Stashed all that stuff in the jeep, emptied my pockets of everything but my iPhone and my jeep key, and proceeded to walk around for a bit as people started showing up and signing in. It was fairly breezy, and there was definitely a storm coming... but it was anyone's guess on when it would actually arrive. It was interesting to see everyone who was participating. If I had to guess, I would say the event was 60-70% women, with a pretty broad distribution of age... as young as 13 to well over 60 (in both genders.) I don't know exactly how many folks were there, but it was well over 300. Eventually it was time to kick things off, and everyone made their way to the start line. All of the 5k and 10k runners were mixed together, starting at the same time. All the walkers and the people with strollers or dogs were in the back. It was pretty chaotic at first, once things started, but it thinned out fairly quickly. The 10k people and the hardcore runners sped ahead of everyone else and the walkers gradually lagged behind. The 5K course was pretty nice, winding around a lake down in Eden Prairie. The 10K course overlapped most of ours, but branched off a couple times too. I didn't run the whole time, but I started the race running and I ended it running, and did a mix of walking and running along the way. I met my goals, which were a) don't ever stop and b) don't be last. The weather managed to hold out for the entire race. It never got too hot, there was a nice breeze and it was mostly overcast. Pretty much perfect in my book. About 20-30 minutes after I left, the rain came down pretty hard. I had a good time, and will most likely do more of them. We'll see.

• Cloud Infrastructure has a new standard

  - by macoracle

  I have been working for more than two years now in the DMTF working group tasked with creating a Cloud Management standard. That work has culminated in the release today of the Cloud Infrastructure Management Interface (CIMI) version 1.0 by the DMTF. CIMI is a single interface that a cloud consumer can use to manage their cloud infrastructure in multiple clouds. As CIMI is adopted by the cloud vendors, no more will you need to adapt client code to each of the proprietary interfaces from these multiple vendors. Unlike a de facto standard where typically one vendor has change control over the interface, and everyone else has to reverse engineer the inner workings of it, CIMI is a de jure standard that is under change control of a standards body. One reason the standard took two years to create is that we factored in use cases, requirements and contributed APIs from multiple vendors. These vendors have products shipping today and as a result CIMI has a strong foundation in real world experience. What does CIMI allow? CIMI is both a model for the resources (computing, storage networking) in the cloud as well as a RESTful protocol binding to HTTP. This means that to create a Machine (guest VM) for example, the client creates a “document” that represents the Machine resource and sends it to the server using HTTP. CIMI allows the resources to be encoded in either JavaScript Object Notation (JSON) or the eXentsible Markup Language (XML). CIMI provides a model for the resources that can be mapped to any existing cloud infrastructure offering on the market. There are some features in CIMI that may not be supported by every cloud, but CIMI also supports the discovery of which features are implemented. This means that you can still have a client that works across multiple clouds and is able to take full advantage of the features in each of them. Isn’t it too early for a standard? A key feature of a successful standard is that it allows for compatible extensions to occur within the core framework of the interface itself. CIMI’s feature discovery (through metadata) is used to convey to the client that additional features that may be vendor specific have been implemented. As multiple vendors implement such features, they become candidates to add the future versions of CIMI. Thus innovation can continue in the cloud space without being slowed down by a lowest common denominator type of specification. Since CIMI was developed in the open by dozens of stakeholders who are already implementing infrastructure clouds, I expect to CIMI being adopted by these same companies and others over the next year or two. Cloud Customers who can see the benefit of this standard should start to ask their cloud vendors to show a CIMI implementation in their roadmap.  For more information on CIMI and the DMTF's other cloud efforts, go to: http://dmtf.org/cloud

• If most of team can't follow the architecture, what do you do?

  - by Chris

  Hi all, I'm working on a greenfields project with two other developers. We're all contractors, and myself and one other just started working on the project while the orginal one has been doing most of the basic framework coding. In the past month, my fellow programmer and I have been just frustrated by the design descisions done by our co-worker. Here's a little background information: The application at face value appeared to be your standard n-layered web application using C# on the 3.5 framework. We have a data layer, business layer and a web interface. But as we got deeper into the project we found some very interesting things that have caused us some troubles. There is a custom data access sqlHelper type base which only accepts dictionary key/valued entries and returns only data tables. There are no entity objects, but there are some massive objects which do everything and then are tossed into session for persitance. The general idea is that the pages (.aspx) don't do anything, while the controls (.ascx) do everything. The general flow is that a client clicks on a button, which goes to a user control base which passes a process request to the 'BLL' class which goes to the page processor, which then goes to a getControlProcessor, which at last actually processes the request. The request itself is made up of a dictionary which is passing a string valued method name, stored procedure name, a control name and possibly a value. All switching of the processing is done by comparing the string values of the control names and method names. Pages are linked together via a common header control that uses a combination of javascript and tables to create a hyperlink effect. And as I found out yesterday, a simple hyperlink between one page and another does not work because of the need to have quite a bit of information in session to determine which control to display on a page. My fellow programmer and I both believe that this is a strange and uncommon approach to web application development. Both of us have been in this business for over five years and neither of us have seen this approach. My question is this, how would we approach our co-worker and voice our concerns and what should we do if he does not want to accept the criteic? We both do not want to insult the work that has been done, but feel that going forward will create a nightmare for development. Thanks for your comments.

• Java Cloud Service for developers

  - by JuergenKress

  The advent of cloud computing has reinvented application development for many companies. “That’s the beauty of the cloud,” says Cameron Purdy, vice president of development, Oracle. “It dramatically improves developer productivity because they can do what they do best without having to manage complex development, testing, staging, and production environments.” The key is to find a platform that doesn’t impose proprietary restrictions or force developers to learn new tools. For example, Oracle Java Cloud Service is an enterprise-grade platform as a service for building and deploying Java EE, Oracle WebLogic Server, and Oracle Application Development Framework (Oracle ADF) applications. “It’s designed to be flexible and easy to use,” says Purdy. “And it is also a standards-based solution -it’s not proprietary and there is no cloud lock-in. Developers get instant access to an enterprise-grade environment for a simple, monthly subscription.” Oracle Java Cloud Service instances are created with just a few clicks, so businesses can create a rich application development environment within minutes. Running on Oracle WebLogic Server and Oracle Exalogic, the underlying infrastructure also leverages Oracle Fusion Middleware’s integration with common services. For example, instances come integrated and preconfigured with optimized Oracle Database and Oracle Identity Management configurations. Based on Oracle Enterprise Manager, the Oracle Java Cloud Service console lets customers easily manage and monitor their Oracle Java Cloud Service instances. The open nature of the Oracle Java Cloud Service lets developers integrate through Web services such as SOAP and REST APIs, as well as use their favorite developer tools, whether they are out-of-the-box tools such as Maven and Ant or the productivity features built into Oracle JDeveloper, Oracle Enterprise Pack for Eclipse, or NetBeans IDE. The service allows for the seamless movement of applications between on-premise Oracle WebLogic Server domains and instances of Oracle Java Cloud Service within Oracle Cloud. This approach allows flexibility to mix and match the use of on-premise environments with cloud instances for development, test, and production environments.

• What Is .recently-used.xbel and How Do I Delete It for Good?

  - by The Geek

  If you’re reading this article, you’ve probably noticed the .recently-used.xbel file in the root of your User folder, and you’re wondering why it keeps constantly coming back even though you repeatedly delete it. So What Is It? The quick answer is that it’s part of the GTK+ library used by a number of cross-platform applications, perhaps the most well-known of which is the Pidgin instant messenger client. As the name implies, the file is used to store a list of the most recently used files. In the case of Pidgin, this comes into play when you are transferring files over IM, and that’s when the file will appear again. Note: this is actually a known and reported bug in Pidgin, but sadly the developers aren’t terribly responsive when it comes to annoyances. Pidgin seems to go for long periods of time without any updates, but we still use it because it’s open-source, cross-platform, and works well. How Do I Get Rid of It? Unfortunately, there’s no way to easily get rid of it, apart from using a different application. If you need to transfer files over Pidgin, the file is going to re-appear… but there’s a quick workaround! The general idea is to set the file properties to Hidden and Read-only. You’d think you could just set it to Hidden and be done with it, but Pidgin will re-create the file every time, so instead we’re leaving the file there and preventing it from being accessed. You could also totally remove access through the Security tab if you wanted to, but this worked fine for me… as you can see, no more file in the folder. Of course, you can’t have the show hidden files and folders option turned on, or the file will continue to show up. Want to get really geeky? You can toggle hidden files with a shortcut key.

• Accessing Controls Within A Gridview

  - by Bunch

  Sometimes you need to access a control within a GridView, but it isn’t quite as straight forward as just using FindControl to grab the control like you can in a FormView. Since the GridView builds multiple rows the key is to specify the row. In this example there is a GridView with a control for a player’s errors. If the errors is greater than 9 the GridView should display the control (lblErrors) in red so it stands out. Here is the GridView: <asp:GridView ID="gvFielding" runat="server" DataSourceID="sqlFielding" DataKeyNames="PlayerID" AutoGenerateColumns="false" >     <Columns>         <asp:BoundField DataField="PlayerName" HeaderText="Player Name" />         <asp:BoundField DataField="PlayerNumber" HeaderText="Player Number" />         <asp:TemplateField HeaderText="Errors">             <ItemTemplate>                 <asp:Label ID="lblErrors" runat="server" Text='<%# EVAL("Errors") %>'  />             </ItemTemplate>         </asp:TemplateField>     </Columns> </asp:GridView> In the code behind you can add the code to change the label’s ForeColor property to red based on the amount of errors. In this case 10 or more errors triggers the color change. Protected Sub gvFielding_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles gvFielding.DataBound     Dim errorLabel As Label     Dim errors As Integer     Dim i As Integer = 0     For Each row As GridViewRow In gvFielding.Rows         errorLabel = gvFielding.Rows(i).FindControl("lblErrors")         If Not errorLabel.Text = Nothing Then             Integer.TryParse(errorLabel.Text, errors)             If errors > 9 Then                 errorLabel.ForeColor = Drawing.Color.Red             End If         End If         i += 1     Next End Sub The main points in the DataBound sub is use a For Each statement to loop through the rows and to increment the variable i so you loop through every row. That way you check each one and if the value is greater than 9 the label changes to red. The If Not errorLabel.Text = Nothing line is there as a check in case no data comes back at all for Errors.

Investors / Partners / Publishers: information and contact forms for companies willing to become Investors/Partners/Publishers or login page to access portal restricted to those who already are. FAQ: list of common questions and answers to guide users and reduce number of support requests. Follow us / Community Facebook / Twitter / Google+: links to the company's pages/accounts on various social networks. Legal Terms / Terms of use / Terms & Conditions: rules users must follow when browsing the website. Privacy / Privacy Statement: explanations as to how the company deals with users' personal data and what users can do about it (request information to be deleted...). cookies: page that starts appearing on more and more websites due to new regulation (notably EU) imposing more transparency and control for users about cookies (e.g. BBC cookie page). Any input is welcome PS: if someone with enough rep could add the footer tag that would be great (min. 300 required).

• June 2013 release of SSDT contains a minor bug that you should be aware of

  - by jamiet

  I have discovered what seems, to me, like a bug in the June 2013 release of SSDT and given the problems that it created yesterday on my current gig I thought it prudent to write this blog post to inform people of it. I’ve built a very simple SSDT project to reproduce the problem that has just two tables, [Table1] and [Table2], and also a procedure [Procedure1]: The two tables have exactly the same definition, both a have a single column called [Id] of type integer. CREATE TABLE [dbo].[Table1] (     [Id] INT NOT NULL PRIMARY KEY ) My stored procedure simply joins the two together, orders them by the column used in the join predicate, and returns the results: CREATE PROCEDURE [dbo].[Procedure1] AS     SELECT t1.*     FROM    Table1 t1     INNER JOIN Table2 t2         ON    t1.Id = t2.Id     ORDER BY Id Now if I create those three objects manually and then execute the stored procedure, it works fine: So we know that the code works. Unfortunately, SSDT thinks that there is an error here: The text of that error is: Procedure: [dbo].[Procedure1] contains an unresolved reference to an object. Either the object does not exist or the reference is ambiguous because it could refer to any of the following objects: [dbo].[Table1].[Id] or [dbo].[Table2].[Id]. Its complaining that the [Id] field in the ORDER BY clause is ambiguous. Now you may well be thinking at this point “OK, just stick a table alias into the ORDER BY predicate and everything will be fine!” Well that’s true, but there’s a bigger problem here. One of the developers at my current client installed this drop of SSDT and all of a sudden all the builds started failing on his machine – he had errors left right and centre because, as it transpires, we have a fair bit of code that exhibits this scenario.  Worse, previous installations of SSDT do not flag this code as erroneous and therein lies the rub. We immediately had a mass panic where we had to run around the department to our developers (of which there are many) ensuring that none of them should upgrade their SSDT installation if they wanted to carry on being productive for the rest of the day. Also bear in mind that as soon as a new drop of SSDT comes out then the previous version is instantly unavailable so rolling back is going to be impossible unless you have created an administrative install of SSDT for that previous version. Just thought you should know! In the grand schema of things this isn’t a big deal as the bug can be worked around with a simple code modification but forewarned is forearmed so they say! Last thing to say, if you want to know which version of SSDT you are running check my blog post Which version of SSDT Database Projects do I have installed? @Jamiet

• Capture a Query Executed By An Application Or User Against a SQL Server Database in Less Than a Minute

  - by Compudicted

  At times a Database Administrator, or even a developer is required to wear a spy’s hat. This necessity oftentimes is dictated by a need to take a glimpse into a black-box application for reasons varying from a performance issue to an unauthorized access to data or resources, or as in my most recent case, a closed source custom application that was abandoned by a deserted contractor without source code. It may not be news or unknown to most IT people that SQL Server has always provided means of back-door access to everything connecting to its database. This indispensible tool is SQL Server Profiler. This “gem” is always quietly sitting in the Start – Programs – SQL Server <product version> – Performance Tools folder (yes, it is for performance analysis mostly, but not limited to) ready to help you! So, to the action, let’s start it up. Once ready click on the File – New Trace button, or using Ctrl-N with your keyboard. The standard connection dialog you have seen in SSMS comes up where you connect the standard way: One side note here, you will be able to connect only if your account belongs to the sysadmin or alter trace fixed server role. Upon a successful connection you must be able to see this initial dialog: At this stage I will give a hint: you will have a wide variety of predefined templates: But to shorten your time to results you would need to opt for using the TSQL_Grouped template. Now you need to set it up. In some cases, you will know the principal’s login name (account) that needs to be monitored in advance, and in some (like in mine), you will not. But it is VERY helpful to monitor just a particular account to minimize the amount of results returned. So if you know it you can already go to the Event Section tab, then click the Column Filters button which would bring a dialog below where you key in the account being monitored without any mask (or whildcard):  If you do not know the principal name then you will need to poke around and look around for things like a config file where (typically!) the connection string is fully exposed. That was the case in my situation, an application had an app.config (XML) file with the connection string in it not encrypted: This made my endeavor very easy. So after I entered the account to monitor I clicked on Run button and also started my black-box application. Voilà, in a under a minute of time I had the SQL statement captured:

• PASS: FY10 Actuals Posted

  - by Bill Graziano

  Earlier this year we published preliminary fiscal year 2010 financials to the Governance page on the PASS web site.  Please remember that FY10 runs from July 1st, 2009 through June 30th, 2010 and includes the November 2009 Summit.  We do our fiscal year this way so that the Summit falls earlier in the fiscal year.  The financials we had posted were P&L numbers at the portfolio level.  Prior to this we had posted our detailed budget but only posted the auditors report at the end of each year.  Today we updated our published financials to include: Pre-audit actuals from FY10 at the same level as our budget.  The document has both actuals and budget for FY10 side by side.  This is over 20 pages of detailed financial information covering hundreds of line-items. A letter describing key differences between our budget and actuals.  I walked through each line item where the difference was greater than $25,000 and explained what happened and why. We updated the financial graph going back to 2003 to include FY10. This update should “close the loop” on our financials.  You can now start with the published budget and compare it to the finished financials at the same level of detail.  We also plan to publish the auditor’s report when that is completed -- as we do every year. Overall I’m very happy with how FY10 turned out.  Keep in mind that this was the November 2009 Summit so we were still facing economic challenges.  With all that we were roughly break-even showing a $15,000 profit on $3.9 million of revenue.  I didn’t find anything shocking in reviewing our actual vs. budget but there were a few things that needed explanation.  You can see those in the letter on the governance page. Please keep in mind that these are the actuals from our operating financials.  The auditor may have us make adjustments for depreciation or other financial transactions.  We may also account for certain transactions differently for tax purposes than we do for financial reporting purposes.  I feel these financial statements give you the clearest picture of how our organization spends its money. We were late publishing these this year.  We were working through some tax issues and that delayed our ability to file our final tax forms which delayed this process.  In hindsight I should have published these documents as soon as we had them and not waited for the tax issues.  We’ll do this better in the future. And on a final note, you don’t need to login to view these documents.  If you have any questions you can post them here.  If we get more than a few questions we may see about creating some forums for financial issues on the PASS web site.

• Speed up your Silverlight Debugging for large projects

  - by Aligned

  I'm working on a 5+ year old ASP.NET project that has 74+ projects and we've been adding new Silverlight applications to run in the ASP.NET page islands. My machine at work isn't the most powerful, so I find myself waiting a lot for the whole thing to build. I'm using Visual Studio 2010, so that takes up a lot of resources as well. This causes me to get distracted and I start looking at the news... I need to combat that more :-). I can't get a new machine, that's up to someone else, so I've found a few tricks to help. 1. Only build the Silverlight project you're working with. This will build all referenced projects (you can see these by right clicking and clicking Project Dependencies) and package a new XAP (you can see all the actions in your output build window). Then refresh your page with the Silverlight app and it's up-to-date. 2. I was working with a co-worker (thanks Jordan) who was using the the Debug -> attach to processes window. In the Attach to: row there is a "Select..." button. In the dialog, click "Debug these code types:" and select Silverlight. Hit ok. Then all you need to do is find your process (you might need to click the refresh button). I'm usually debugging in IE, so I select the first one and push "i" on the keyboard. That brings me to the IE windows open. Find the one with type of Silverlight, x86. It is usually directly above one with type of x86 that has the page title for "title". Click attach and watch your output window spit out messages about loading debug symbols and your breakpoints enabled (if this doesn't happen you chose the wrong process, hit stop and try again). Now you can debug the client code as normal, server code requires a full F5 or attaching to the correct process. To improve this even further, bind the menu item to a key stroke. I chose ctrl + x, x. (Tools -> Options -> Keyboard, search for Debug.AttachToProcess, set the shortcut keys globaly and assign). Most of the time I build the project, then hit ctrl + x, x then i, then enter and I'm debugging. The process I want is usually the first IE in the list.

• Unintentional run-in with C# thread concurrency

  - by geekrutherford

  For the first time today we began conducting load testing on a ASP.NET application already in production. Obviously you would normally want to load test prior to releasing to a production environment, but that isn't the point here.   We ran a test which simulated 5 users hitting the application doing the same actions simultaneously. The first few pages visited seemed fine and then things just hung for a while before the test failed. While the test was running I was viewing the performance counters on the server noting that the CPU was consistently pegged at 100% until the testing tool gave up.   Fortunately the application logs all exceptions including those unhandled to the database (thanks to log4net). I checked the log and low and behold the error was:   System.ArgumentException: An item with the same key has already been added. (The rest of the stack trace intentionally omitted)   Since the code was running with debug on the line number where the exception occured was also provided. I began inspecting the code and almost immediately it hit me, the section of code responsible for the exception is trying to initialize a static class. My next question was how is this code being hit multiple times when I have a rudimentary check already in place to prevent this kind of thing (i.e. a check on a public variable of the static class before entering the initializing routine). The answer...the check fails because the value is not set before other threads have already made it through.   Not being one who consistently works with threading I wasn't quite sure how to handle this problem. Fortunately a co-worker recalled having to lock a section of code in the past but couldn't recall exactly how. After a quick search on Google the solution is as follows:   Object objLock = new Object(); lock(objLock) { //logic requiring lock }   The lock statement takes an object and tells the .NET runtime that the current thread has exclusive access while the code within brackets is executing. Once the code completes, the lock is released for another thread to utilize.   In my case, I only need to execute the inner code once to initialize my static class. So within the brackets I have a check on a public variable to prevent it from being initialized again.

• Nails vs Screws (C# List vs Dictionary)

  - by MarkPearl

  General This may sound like a typical noob statement, but I’m finding out in a very real way that just because you have a solution to a problem, doesn’t necessarily mean it is the best solution. This was reiterated to me when a friend of mine suggested I look at using Dictionaries instead of Lists for a particular problem – he was right, I have always just assumed that because lists solved my problem I did not need to look elsewhere. So my new manifesto to counter this ageless problem is as follows… Look for a solution that will logically work Once you have a solution look for possible alternatives Decide why your current solution is the best approach compared to the alternatives If it is.. use it till something better comes along, if it isnt…. change What’s the difference between Lists & Dictionaries Both lists and dictionaries are used to store collections of data. Assume we had the following declarations… var dic = new Dictionary<string, long>(); var lst = new List<long>(); long data;   With a list, you simply add the item to the list and it will add the item to the end of the list. lst.Add(data); With a dictionary, you need to specify some sort of key and the data you want to add so that it can be uniquely identified. dic.Add(uniquekey, data);   Because with a dictionary you now have unique identifier, in the background they provide all sort’s of optimized algorithms to find your associated data. What this means is that if you are wanting to access your data it is a lot faster than a List. So when is it appropriate to use either class? For me, if I can guarantee that each item in my collection will have a unique identifier, then I will use Dictionaries instead of Lists as there is a considerable performance benefit when accessing each data item. If I cannot make this sort of guarantee, then by default I will use a list. I know this is all really basic, and I hope I haven’t missed some fundamental principle… If anyone would like to add their 2 cents, please feel free to do so…
