• SQL Saturday 43 (Redmond, WA) Review

  - by BuckWoody

  Last Saturday (June 12th) we held a “SQL Saturday” (more about those here) event in Redmond, Washington. The event was held at the Microsoft campus, at the Mixer in our new location called the “Commons”. This is a mall-like area that we have on campus, and the Mixer is a large building with lots of meeting rooms, so it made a perfect location for the event. There was a sign to find the parking, and once there they had a sign to show how to get to the building. Since it’s a secure facility, Greg Larsen and crew had a person manning the door so that even late arrivals could get in. We had about 400 sign up for the event, and a little over 300 attend (official numbers later). I think we would have had a lot more, but the sun was out – and you just can’t underestimate the effect of that here in the Pacific Northwest. We joke a lot about not seeing the sun much, but when a day like what we had on Saturday comes around, and on a weekend at that, you’d cancel your wedding to go outside to play in the sun. And your spouse would agree with you for doing it. We had some top-notch speakers, including Clifford Dibble and Kalen Delany. The food was great, we had multiple sponsors (including Confio who seems to be at all of these) and the attendees were from all over the professional spectrum, from developers to BI to DBA’s. Everyone I saw was very engaged, and when I visited room-to-room I saw almost no one in the halls – everyone was in the sessions. I also saw a much larger Microsoft presence this year, especially from Dan Jones’ team. I had a great turnout at my session, and yes, I was wearing an Oracle staff shirt. I did that because I wanted to show that the session I gave on “SQL Server for the Oracle DBA” was non-marketing – I couldn’t exactly bash Oracle wearing their colors! These events are amazing. I can’t emphasize enough how much I appreciate the volunteers and how much work they put into these events, and to you for coming. If you’re reading this and you haven’t attended one yet, definitely find out if there is one in your area – and if not, start one. It’s a lot of work, but it’s totally worth it.       Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• The Solution

  - by Patrick Liekhus

  So I recently attended a class about time management as well as read the book “The Seven Habits of Highly Effective People” by Stephen Covey.  Both have been instrumental in helping me get my priorities aligned as well as keep me focused. The reason I bring this up is that it gave me a great idea for a small application with which to create a great technical stack solution that would be easy to demo and explain.  Therefore, the project from this point forward with be the Liekhus.TimeTracker application which will bring some the time management skills that I have acquired into a technical implementation.  The idea is rather simple, but leverages some of the basic principles of Covey along with some of the worksheets that I garnered from class.  The basics are as such: 1) a plan is a must have and 2) write it down!  A plan not written down is just an idea.  How many times have you had an idea that didn’t materialize?  Exactly.  Hence why I am writing it all down now! The worksheet consists of a few simple columns that I will outline below as well as some modifications that I made according to the Covey habits.  The worksheet looks like the following: Status Issue Area CQ Notes P  F  L     1234   P  F  L     1234   P  F  L     1234   P  F  L     1234   P  F  L     1234   P  F  L     1234   P  F  L     1234   P  F  L     1234   P  F  L     1234   The idea is really simple and straightforward; you write down all your tasks and keep track of them along the way.  The status stands for (P)ending, (F)inished or (L)ater.  You write a quick title for the issue and select the CQ (Covey Quadrant) with which the issue occurs.  The notes section is for things that happen while you are working through the issue.  And last, but not least, is the Area column that I added as a way to identify the Role or Area of your life that this task falls within based upon Covey’s teachings. The second part of this application is a simple phone log that allows you to track your phone conversations throughout the day.  All of this is currently done on a sheet of paper, but being involved in technology, I want it to have bells and whistles.  Therefore, this is my simple idea for a project that will allow me to test my theories about coding and implementations.  Stay tuned as the next session will be flushing out the concept and coming up with user stories to begin the SCRUM process. Thanks

• Birt on Tomcat unable to find JARs

  - by LostInTheWoods

  First, my setup: BiRT Runtime: 3.7.2. Ubuntu 10.04 Tomcat 6 Sun Java 1.6.0 I have a jar file I want to deploy onto the Tomcat server so it is usable by the runtime, so I placed the jar file in /var/lib/tomcat6/webapps/birt/WEB-INF/lib. As I understand it this is the default location for JAR files that are going to be used by a BiRT report. But the jar file is not accessible by the report that is trying to call it. In the BiRT logs I see: Error evaluating Javascript expression. Script engine error: ReferenceError: "DynDSinfo" is not defined. (/report/data-sources/oda-data-source[@id="54"]/method[@name="beforeOpen"]#20) Script source: /report/data-sources/oda-data-source[@id="54"]/method[@name="beforeOpen"], line: 0, text: __bm_beforeOpen() org.eclipse.birt.data.engine.core.DataException: Fail to execute script in function __bm_beforeOpen(). Source: "DynDSinfo" is the class I am trying to reference.. and now for the kicker... this works fine on Tomcat6 on Windows 7. The same files in the same places. So is there some additional configuration or some environmental variable that needs to be set, or something different on the Linux (Ubuntu) platform? All help or ideas gratefully received, Stephen

• SQL Query to update parent record with child record values

  - by Wells

  I need to create a Trigger that fires when a child record (Codes) is added, updated or deleted. The Trigger stuffs a string of comma separated Code values from all child records (Codes) into a single field in the parent record (Projects) of the added, updated or deleted child record. I am stuck on writing a correct query to retrieve the Code values from just those child records that are the children of a single parent record. -- Create the test tables CREATE TABLE projects ( ProjectId varchar(16) PRIMARY KEY, ProjectName varchar(100), Codestring nvarchar(100) ) GO CREATE TABLE prcodes ( CodeId varchar(16) PRIMARY KEY, Code varchar (4), ProjectId varchar(16) ) GO -- Add sample data to tables: Two projects records, one with 3 child records, the other with 2. INSERT INTO projects (ProjectId, ProjectName) SELECT '101','Smith' UNION ALL SELECT '102','Jones' GO INSERT INTO prcodes (CodeId, Code, ProjectId) SELECT 'A1','Blue', '101' UNION ALL SELECT 'A2','Pink', '101' UNION ALL SELECT 'A3','Gray', '101' UNION ALL SELECT 'A4','Blue', '102' UNION ALL SELECT 'A5','Gray', '102' GO I am stuck on how to create a correct Update query. Can you help fix this query? -- Partially working, but stuffs all values, not just values from chile (prcodes) records of parent (projects) UPDATE proj SET proj.Codestring = (SELECT STUFF((SELECT ',' + prc.Code FROM projects proj INNER JOIN prcodes prc ON proj.ProjectId = prc.ProjectId ORDER BY 1 ASC FOR XML PATH('')),1, 1, '')) The result I get for the Codestring field in Projects is: ProjectId ProjectName Codestring 101 Smith Blue,Blue,Gray,Gray,Pink ... But the result I need for the Codestring field in Projects is: ProjectId ProjectName Codestring 101 Smith Blue,Pink,Gray ... Here is my start on the Trigger. The Update query, above, will be added to this Trigger. Can you help me complete the Trigger creation query? CREATE TRIGGER Update_Codestring ON prcodes AFTER INSERT, UPDATE, DELETE AS WITH CTE AS ( select ProjectId from inserted union select ProjectId from deleted )

• Pigs in Socks?

  - by MightyZot

  My wonderful wife Annie surprised me with a cruise to Cozumel for my fortieth birthday. I love to travel. Every trip is ripe with adventure, crazy things to see and experience. For example, on the way to Mobile Alabama to catch our boat, some dude hauling a mobile home lost a window and we drove through a cloud of busting glass going 80 miles per hour! The night before the cruise, we stayed in the Malaga Inn and I crawled UNDER the hotel to look at an old civil war bunker. WOAH! Then, on the way to and from Cozumel, the boat plowed through two beautiful and slightly violent storms. But, the adventures you have while travelling often pale in comparison to the cult of personalities you meet along the way.  :) We met many cool people during our travels and we made some new friends. Todd and Andrea are in the publishing business (www.myneworleans.com) and teaching, respectively. Erika is a teacher too and Matt has a pig on his foot. This story is about the pig. Without that pig on Matt’s foot, we probably would have hit a buoy and drowned. Alright, so…this pig on Matt’s foot…this is no henna tatt, this is a man’s tattoo. Apparently, getting tattoos on your feet is very painful because there is very little muscle and fat and lots of nifty nerves to tell you that you might be doing something stupid. Pig and rooster tattoos carry special meaning for sailors of old. According to some sources, having a tattoo of a pig or rooster on one foot or the other will keep you from drowning. There are many great musings as to why a pig and a rooster might save your life. The most plausible in my opinion is that pigs and roosters were common livestock tagging along with the crew. Since they were shipped in wooden crates, pigs and roosters were often counted amongst the survivors when ships succumbed to Davy Jones’ Locker. I didn’t spend a whole lot of time researching the pig and the rooster, so consider these musings as you would a grain of salt. And, I was not able to find a lot of what you might consider credible history regarding the tradition. What I did find was a comfort, or solace, in the maritime tradition. Seems like raw traditions like the pig and the rooster are in danger of getting lost in a sea of non-permanence. I mean, what traditions are us old programmers and techies leaving behind for future generations? Makes me wonder what Ward Christensen has tattooed on his left foot.  I guess my choice would have to be a Commodore 64.   (I met Ward, by the way, in an elevator after he received his Dvorak awards in 1992. He was a very non-assuming individual sporting business casual and was very much a “sailor” of an old-school programmer. I can’t remember his exact words, but I think they were essentially that he felt it odd that he was getting an award for just doing his work. I’m sure that Ward doesn’t know this…he couldn’t have set a more positive example for a young 22 year old programmer. Thanks Ward!)

• SQL SERVER – Merge Operations – Insert, Update, Delete in Single Execution

  - by pinaldave

  This blog post is written in response to T-SQL Tuesday hosted by Jorge Segarra (aka SQLChicken). I have been very active using these Merge operations in my development. However, I have found out from my consultancy work and friends that these amazing operations are not utilized by them most of the time. Here is my attempt to bring the necessity of using the Merge Operation to surface one more time. MERGE is a new feature that provides an efficient way to do multiple DML operations. In earlier versions of SQL Server, we had to write separate statements to INSERT, UPDATE, or DELETE data based on certain conditions; however, at present, by using the MERGE statement, we can include the logic of such data changes in one statement that even checks when the data is matched and then just update it, and similarly, when the data is unmatched, it is inserted. One of the most important advantages of MERGE statement is that the entire data are read and processed only once. In earlier versions, three different statements had to be written to process three different activities (INSERT, UPDATE or DELETE); however, by using MERGE statement, all the update activities can be done in one pass of database table. I have written about these Merge Operations earlier in my blog post over here SQL SERVER – 2008 – Introduction to Merge Statement – One Statement for INSERT, UPDATE, DELETE. I was asked by one of the readers that how do we know that this operator was doing everything in single pass and was not calling this Merge Operator multiple times. Let us run the same example which I have used earlier; I am listing the same here again for convenience. --Let’s create Student Details and StudentTotalMarks and inserted some records. USE tempdb GO CREATE TABLE StudentDetails ( StudentID INTEGER PRIMARY KEY, StudentName VARCHAR(15) ) GO INSERT INTO StudentDetails VALUES(1,'SMITH') INSERT INTO StudentDetails VALUES(2,'ALLEN') INSERT INTO StudentDetails VALUES(3,'JONES') INSERT INTO StudentDetails VALUES(4,'MARTIN') INSERT INTO StudentDetails VALUES(5,'JAMES') GO CREATE TABLE StudentTotalMarks ( StudentID INTEGER REFERENCES StudentDetails, StudentMarks INTEGER ) GO INSERT INTO StudentTotalMarks VALUES(1,230) INSERT INTO StudentTotalMarks VALUES(2,255) INSERT INTO StudentTotalMarks VALUES(3,200) GO -- Select from Table SELECT * FROM StudentDetails GO SELECT * FROM StudentTotalMarks GO -- Merge Statement MERGE StudentTotalMarks AS stm USING (SELECT StudentID,StudentName FROM StudentDetails) AS sd ON stm.StudentID = sd.StudentID WHEN MATCHED AND stm.StudentMarks > 250 THEN DELETE WHEN MATCHED THEN UPDATE SET stm.StudentMarks = stm.StudentMarks + 25 WHEN NOT MATCHED THEN INSERT(StudentID,StudentMarks) VALUES(sd.StudentID,25); GO -- Select from Table SELECT * FROM StudentDetails GO SELECT * FROM StudentTotalMarks GO -- Clean up DROP TABLE StudentDetails GO DROP TABLE StudentTotalMarks GO The Merge Join performs very well and the following result is obtained. Let us check the execution plan for the merge operator. You can click on following image to enlarge it. Let us evaluate the execution plan for the Table Merge Operator only. We can clearly see that the Number of Executions property suggests value 1. Which is quite clear that in a single PASS, the Merge Operation completes the operations of Insert, Update and Delete. I strongly suggest you all to use this operation, if possible, in your development. I have seen this operation implemented in many data warehousing applications.

• My new laptop - with a really nice battery option

  - by Rob Farley

  It was about time I got a new laptop, and so I made a phone-call to Dell to discuss my options. I decided not to get an SSD from them, because I’d rather choose one myself – the sales guy tells me that changing the HD doesn’t void my warranty, so that’s good (incidentally, I’d love to hear people’s recommendations for which SSD to get for my laptop). Unfortunately this machine only has one HD slot, but I figure that I’ll put lots of stuff onto external disks anyway. The machine I got was a Dell Studio XPS 16. It’s red (which suits my company), but also has the Intel® Core™ i7-820QM Processor, which is 4 Cores/8 Threads. Makes for a pretty Task Manager, but nothing like the one I saw at SQLBits last year (at 96 cores), or the one that my good friend James Rowland-Jones writes about here. But the reason for this post is actually something in the software that comes with the machine – you know, the stuff that most people uninstall at the earliest opportunity. I had just reinstalled the operating system, and was going through the utilities to get the drivers up-to-date, when I noticed that one of Dell applications included an option to disable battery charging. So I installed it. And sure enough, I can tell the battery not to charge now. Clearly Dell see it as a temporary option, and one that’s designed for when you’re on a plane. But for me, I most often use my laptop with the power plugged in, which means I don’t need to have my battery continually topping itself up. So I really love this option, but I feel like it could go a little further. I’d like “Not Charging” to be the default option, and let me set it when I want to charge it (which should theoretically make my battery last longer). I also intend to work out how this option works, so that I can script it and put it into my StartUp options (so it can be the Default setting). Actually – if someone has already worked this out and can tell me what it does, then please feel free to let me know. Even better would be an external switch. I had a switch on my old laptop (a Dell Latitude) for WiFi, so that I could turn that off before I turned on the computer (this laptop doesn’t give me that option – no physical switch for flight mode). I guess it just means I’ll get used to leaving the WiFi off by default, and turning it on when I want it – might save myself some battery power that way too. Soon I’ll need to take the plunge and sync my iPhone with the new laptop. I’m a little worried that I might lose something – Apple’s messages about how my stuff will be wiped and replaced with what’s on the PC doesn’t fill me with confidence, as it’s a new PC that doesn’t have stuff on it. But having a new machine is definitely a nice experience, and one that I can recommend. I’m sure when I get around to buying an SSD I’ll feel like it’s shiny and new all over again!

• Travelling MVP #4: DevReach 2012

  - by DigiMortal

  Our next stop after Varna was Sofia where DevReach happens. DevReach is one of my favorite conferences in Europe because of sensible prices and strong speakers line-up. Also they have VIP-party after conference and this is good event to meet people you don’t see every day, have some discussion with speakers and find new friends. Our trip from Varna to Sofia took about 6.5 hours on bus. As I was tired from last evening it wasn’t problem for me as I slept half the trip. After smoking pause in Velike Tarnovo I watched movies from bus TV. We had supper later in city center Happy’s – place with good meat dishes and nice service. And next day it begun…. :) DevReach 2012 DevReach is held usually in Arena Mladost. It’s near airport and Telerik office. The event is organized by local MVP Martin Kulov together with Telerik. Two days of sessions with strong speakers is good reason enough for me to go to visit some event. Some topics covered by sessions: Windows 8 development web development SharePoint Windows Azure Windows Phone architecture Visual Studio Practically everybody can find some interesting session in every time slot. As the Arena is not huge it is very easy to go from one sessions to another if selected session for time slot is not what you expected. On the second floor of Arena there are many places where you can eat. There are simple chunk-food places like Burger King and also some restaurants. If you are hungry you will find something for your taste for sure. Also you can buy beer if it is too hot outside :) Weather was very good for October – practically Estonian summer – 25C and over. Sessions I visited Here is the list of sessions I visited at DevReach 2012: DevReach 2012 Opening & Welcome Messsage with Martin Kulov and Stephen Forte Principled N-Tier Solution Design with Steve Smith Data Patterns for the Cloud with Brian Randell .NET Garbage Collection Performance Tips with Sasha Goldshtein Building Secured, Scalable, Low-latency Web Applications with the Windows Azure Platform with Ido Flatow It’s a Knockout! MVVM Style Web Applications with Charles Nurse Web Application Architecture – Lessons Learned from Adobe Brackets with Brian Rinaldi Demystifying Visual Studio 2012 Performance Tools with Martin Kulov SPvNext – A Look At All the Exciting And New Features In SharePoint with Sahil Malik Portable Libraries – Why You Should Care with Lino Tadros I missed some sessions because of some death march projects that are going and that I have to coordinate but it was not big loss as I had time to walk around in session venue neighborhood and see Sofia Business Park. Next year again! I will be there again next year and hopefully more guys from Estonia will join me. I think it’s good idea to take short vacation for DevReach time and do things like we did this time – Bucharest, Varna, Sofia. It’s only good idea to plan some more free time so we are not very much in hurry and also we have no work stuff to do on the trip. This far this trip has been one of best trips I have organized and I will go and meet all those guys in this region again! :)

And who could? Stephen King said it best in his review when he referred to the Collins’ novel as “a violent, jarring speed-rap of a novel that generates nearly constant suspense and may also generate a fair amount of controversy”. So what’s the tie in for IT? Let’s leave the dystopia of District 12 and come back to today’s reality. This is the world of radical IT paradigm shifts that haven’t been seen since Java was introduced in 1995. Everything you learned in school is probably outdated as of Friday. And everything you learned on Friday will probably change when you get to work on Monday. Nevertheless, we’re eager, we’re aspiring, we’re hungry to learn. While the challenges upon us may not rival the venomous bees (or ‘tracker jackers’) seen in this blockbuster, there are certainly obstacles to be found. In preparation, I leave you two pieces of advice - aside from avoiding werewolves… Learn the Cloud If you had asked me what to learn in 1995, I would have said, “Go learn Java”. But now my advice is “Go learn Java and then learn Cloud”. Cloud computing and Java go hand in hand. This is especially true for Oracle’s own Public Cloud which uses Java (via WebLogic 12c) as well as Oracle Database at its core foundation. Understanding the connotations of elasticity, scale, virtualization, and multi-tenancy, (to name just a few) requires a strong foundation in computer science and especially Java to get it right. Without Java, the Cloud is nothing more than a brittle application meagerly deployed on the internet. Get Social and Actively Participate And at all levels. Socializing your ideas internally is dreadfully important. And this means socializing and communicating your good ideas to lines of business, to architects, business analysts, developers, DBAs and Operations. But don’t forget to go external. Stay current by being on the lookout for blogs, tweets, webcasts, papers, podcasts and videos for your technology area. Be not just a subscriber but a participant in these channels as well. Attend industry and vendor sponsored events to learn from the experts – and seek out opportunities to stay connected with those that are smarter than you. You’ll gain more understanding if you participate actively. At the same time you’ll make friends (and allies) and you’ll be glad you did. Tell help you get social and actively participate [while learning the Cloud] here are a couple of pointers for you: See our website on Cloud and Fusion Middleware Subscribe to our regular Fusion Middleware Newsletter Follow us on Twitter and Facebook Find us at one of our key events Meanwhile, happy IT hunger games!

• Write TSQL, win a Kindle.

  - by Fatherjack

  So recently Red Gate launched sqlmonitormetrics.red-gate.com and showed the world how to embed your own scripts harmoniously in a third party tool to get the details that you want about your SQL Server performance. The site has a way to submit your own metrics and take a copy of the ones that other people have submitted to build a library of code to keep track of key metrics of your servers performance. There have been several submissions already but they have now launched a competition to provide an incentive for you to get creative and show us what you can do with a bit of TSQL and the SQL Monitor framework*. What’s it worth? Well, if you are one of the 3 winners then you get to choose either a Kindle Fire or $199. How do you win? Simply write the T-SQL for a SQL Monitor custom metric and the relevant description and introduction for it and submit it via  sqlmonitormetrics.red-gate.com before 14th Sept 2012 and then sit back and wait while the judges review your code and your aims in writing the metric. Who are the judges and how will they judge the metrics? There are two judges for this competition, Steve Jones (Microsoft SQL Server MVP, co-founder of SQLServerCentral.com, author, blogger etc) and Jonathan Allen (um, yeah, Steve has done all the good stuff, I’m here by good fortune). We will be looking to rate the metrics on each of 3 criteria: how the metric can help with performance tuning SQL Server. how having the metric running enables DBA’s to meet best practice. how interesting /original the idea for the metric is. Our combined decision will be final etc etc **  What happens to my metric? Any metrics submitted to the competition will be automatically entered into the site library and become available for sharing once the competition is over. You’ll get full credit for metrics you submit regardless of the competition results. You can enter as many metrics as you like. How long does it take? Honestly? Once you have the T-SQL sorted then so long as you can type your name and your email address you are done : http://sqlmonitormetrics.red-gate.com/share-a-metric/ What can I monitor? If you really really want a Kindle or $199 (and let’s face it, who doesn’t? ) and are momentarily stuck for inspiration, take a look at these example custom metrics that have been written by Stuart Ainsworth, Fabiano Amorim, TJay Belt, Louis Davidson, Grant Fritchey, Brad McGehee and me  to start the library off. There are some great pieces of TSQL in those metrics gathering important stats about how SQL Server is performing.   * – framework may not be the best word here but I was under pressure and couldnt think of a better one. If you prefer try ‘engine’, or ‘application’? I don’t know, pick something that makes sense to you. ** – for the full (legal) version of the rules check the details on sqlmonitormetrics.red-gate.com or send us an email if you want any point clarified. Disclaimer – Jonathan is a Friend of Red Gate and as such, whenever they are discussed, will have a generally positive disposition towards Red Gate tools. Other tools are often available and you should always try others before you come back and buy the Red Gate ones.

• The Oracle Retail Week Awards - most exciting awards yet?

  - by sarah.taylor(at)oracle.com

  Last night's annual Oracle Retail Week Awards saw the UK's top retailers come together to celebrate the very best of our industry over the last year.  The Grosvenor House Hotel on Park Lane in London was the setting for an exciting ceremony which this year marked several significant milestones in British - and global - retail.  Check out our videos about the event at our Oracle Retail YouTube channel, and see if you were snapped by our photographer on our Oracle Retail Facebook page. There were some extremely hot contests for many of this year's awards - and all very deserving winners.  The entries have demonstrated beyond doubt that retailers have striven to push their standards up yet again in all areas over the past year.  The judging panel includes some of the most prestigious names in the retail industry - to impress the panel enough to win an award is a substantial achievement.  This year the panel included the likes of Andy Clarke - Chief Executive of ASDA Group; Mark Newton Jones - CEO of Shop Direct Group; Richard Pennycook - the finance director at Morrisons; Rob Templeman - Chief Executive of Debenhams; and Stephen Sunnucks - the president of Gap Europe.  These are retail veterans  who have each helped to shape the British High Street over the last decade.  It was great to chat with many of them in the Oracle VIP area last night.  For me, last night's highlight was honouring both Sir Stuart Rose and Sir Terry Leahy for their contributions to the retail industry.  Both have set the standards in retailing over the last twenty years and taken their respective businesses from strength to strength, demonstrating that there is always a need for innovation even in larger businesses, and that a business has to adapt quickly to new technology in order to stay competitive.  Sir Terry Leahy's retirement this year marks the end of an era of global expansion for the Tesco group and a milestone in the progression of British retail.  Sir Terry has helped steer Tesco through nearly 20 years of change, with 14 years as Chief Executive.  During this time he led the drive for international expansion and an aggressive campaign to increase market share.  He has led the way for High Street retailers in adapting to the rise of internet retailing and nurtured a very successful home delivery service.  More recently he has pioneered the notion of cross-channel retailing with the introduction of Tesco apps for the iPhone and Android mobile phones allowing customers to scan barcodes of items to add to a shopping list which they can then either refer to in store or order for delivery.  John Lewis Partnership was a very deserving winner of The Oracle Retailer of the Year award for their overall dedication to excellent retailing practices.  The business was also named the American Express Marketing/Advertising Campaign of the Year award for their memorable 'Never Knowingly Undersold' advert series, which included a very successful viral video and radio campaign with Fyfe Dangerfield's cover of Billy Joel's 'She's Always a Woman' used for the adverts.  Store Design of the Year was another exciting category with Topshop taking the accolade for its flagship Oxford Street store in London, which combines boutique concession-style stalls with high fashion displays and exclusive collections from leading designers.  The store even has its own hairdressers and food hall, making it a truly all-inclusive fashion retail experience and a global landmark for any self-respecting international fashion shopper. Over the next few weeks we'll be exploring some of the winning entries in more detail here on the blog, so keep an eye out for some unique insights into how the winning retailers have made such remarkable achievements.

• Thinktecture.IdentityModel: Comparing Strings without leaking Timinig Information

  - by Your DisplayName here!

  Paul Hill commented on a recent post where I was comparing HMACSHA256 signatures. In a nutshell his complaint was that I am leaking timing information while doing so – or in other words, my code returned faster with wrong (or partially wrong) signatures than with the correct signature. This can be potentially used for timing attacks like this one. I think he got a point here, especially in the era of cloud computing where you can potentially run attack code on the same physical machine as your target to do high resolution timing analysis (see here for an example). It turns out that it is not that easy to write a time-constant string comparer due to all sort of (unexpected) clever optimization mechanisms in the CLR. With the help and feedback of Paul and Shawn I came up with this: Structure the code in a way that the CLR will not try to optimize it In addition turn off optimization (just in case a future version will come up with new optimization methods) Add a random sleep when the comparison fails (using Shawn’s and Stephen’s nice Random wrapper for RNGCryptoServiceProvider). You can find the full code in the Thinktecture.IdentityModel download. [MethodImpl(MethodImplOptions.NoOptimization)] public static bool IsEqual(string s1, string s2) {     if (s1 == null && s2 == null)     {         return true;     }       if (s1 == null || s2 == null)     {         return false;     }       if (s1.Length != s2.Length)     {         return false;     }       var s1chars = s1.ToCharArray();     var s2chars = s2.ToCharArray();       int hits = 0;     for (int i = 0; i < s1.Length; i++)     {         if (s1chars[i].Equals(s2chars[i]))         {             hits += 2;         }         else         {             hits += 1;         }     }       bool same = (hits == s1.Length * 2);       if (!same)     {         var rnd = new CryptoRandom();         Thread.Sleep(rnd.Next(0, 10));     }       return same; }

• Bitmask data insertions in SSDT Post-Deployment scripts

  - by jamiet

  On my current project we are using SQL Server Data Tools (SSDT) to manage our database schema and one of the tasks we need to do often is insert data into that schema once deployed; the typical method employed to do this is to leverage Post-Deployment scripts and that is exactly what we are doing. Our requirement is a little different though, our data is split up into various buckets that we need to selectively deploy on a case-by-case basis. I was going to use a SQLCMD variable for each bucket (defaulted to some value other than “Yes”) to define whether it should be deployed or not so we could use something like this in our Post-Deployment script: IF ($(DeployBucket1Flag) = 'Yes')BEGIN   :r .\Bucket1.data.sqlENDIF ($(DeployBucket2Flag) = 'Yes')BEGIN   :r .\Bucket2.data.sqlENDIF ($(DeployBucket3Flag) = 'Yes')BEGIN   :r .\Bucket3.data.sqlEND That works fine and is, I’m sure, a very common technique for doing this. It is however slightly ugly because we have to litter our deployment with various SQLCMD variables. My colleague James Rowland-Jones (whom I’m sure many of you know) suggested another technique – bitmasks. I won’t go into detail about how this works (James has already done that at Using a Bitmask - a practical example) but I’ll summarise by saying that you can deploy different combinations of the buckets simply by supplying a different numerical value for a single SQLCMD variable. Each bit of that value’s binary representation signifies whether a particular bucket should be deployed or not. This is better demonstrated using the following simple script (which can be easily leveraged inside your Post-Deployment scripts): /* $(DeployData) is a SQLCMD variable that would, if you were using this in SSDT, be declared in the SQLCMD variables section of your project file. It should contain a numerical value, defaulted to 0. In this example I have declared it using a :setvar statement. Test the affect of different values by changing the :setvar statement accordingly. Examples: :setvar DeployData 1 will deploy bucket 1 :setvar DeployData 2 will deploy bucket 2 :setvar DeployData 3   will deploy buckets 1 & 2 :setvar DeployData 6   will deploy buckets 2 & 3 :setvar DeployData 31  will deploy buckets 1, 2, 3, 4 & 5 */ :setvar DeployData 0 DECLARE  @bitmask VARBINARY(MAX) = CONVERT(VARBINARY,$(DeployData)); IF (@bitmask & 1 = 1) BEGIN     PRINT 'Bucket 1 insertions'; END IF (@bitmask & 2 = 2) BEGIN     PRINT 'Bucket 2 insertions'; END IF (@bitmask & 4 = 4) BEGIN     PRINT 'Bucket 3 insertions'; END IF (@bitmask & 8 = 8) BEGIN     PRINT 'Bucket 4 insertions'; END IF (@bitmask & 16 = 16) BEGIN     PRINT 'Bucket 5 insertions'; END An example of running this using DeployData=6 The binary representation of 6 is 110. The second and third significant bits of that binary number are set to 1 and hence buckets 2 and 3 are “activated”. Hope that makes sense and is useful to some of you! @Jamiet P.S. I used the awesome HTML Copy feature of Visual Studio’s Productivity Power Tools in order to format the T-SQL code above for this blog post.

• 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.

• PASS Summit 2011 &ndash; Part II

  - by Tara Kizer

  I arrived in Seattle last Monday afternoon to attend PASS Summit 2011.  I had really wanted to attend Gail Shaw’s (blog|twitter) and Grant Fritchey’s (blog|twitter) pre-conference seminar “All About Execution Plans” on Monday, but that would have meant flying out on Sunday which I couldn’t do.  On Tuesday, I attended Allan Hirt’s (blog|twitter) pre-conference seminar entitled “A Deep Dive into AlwaysOn: Failover Clustering and Availability Groups”.  Allan is a great speaker, and his seminar was packed with demos and information about AlwaysOn in SQL Server 2012.  Unfortunately, I have lost my notes from this seminar and the presentation materials are only available on the pre-con DVD.  Hmpf! On Wednesday, I attended Gail Shaw’s “Bad Plan! Sit!”, Andrew Kelly’s (blog|twitter) “SQL 2008 Query Statistics”, Dan Jones’ (blog|twitter) “Improving your PowerShell Productivity”, and Brent Ozar’s (blog|twitter) “BLITZ! The SQL – More One Hour SQL Server Takeovers”.  In Gail’s session, she went over how to fix bad plans and bad query patterns.  Update your stale statistics! How to fix bad plans Use local variables – optimizer can’t sniff it, so it’ll optimize for “average” value Use RECOMPILE (at the query or stored procedure level) – CPU hit OPTIMIZE FOR hint – most common value you’ll pass How to fix bad query patterns Don’t use them – ha! Catch-all queries Use dynamic SQL OPTION (RECOMPILE) Multiple execution paths Split into multiple stored procedures OPTION (RECOMPILE) Modifying parameter values Use local variables Split into outer and inner procedure OPTION (RECOMPILE) She also went into “last resort” and “very last resort” options, but those are risky unless you know what you are doing.  For the average Joe, she wouldn’t recommend these.  Examples are query hints and plan guides. While I enjoyed Andrew’s session, I didn’t take any notes as it was familiar material.  Andrew is a great speaker though, and I’d highly recommend attending his sessions in the future. Next up was Dan’s PowerShell session.  I need to look into profiles, manifests, function modules, and function import scripts more as I just didn’t quite grasp these concepts.  I am attending a PowerShell training class at the end of November, so maybe that’ll help clear it up.  I really enjoyed the Excel integration demo.  It was very cool watching PowerShell build the spreadsheet in real-time.  I must look into this more!  On a side note, I am jealous of Dan’s hair.  Fabulous hair! Brent’s session showed us how to quickly gather information about a server that you will be taking over database administration duties for.  He wrote a script to do a fast health check and then later wrapped it into a stored procedure, sp_Blitz.  I can’t wait to use this at my work even on systems where I’ve been the primary DBA for years, maybe there’s something I’ve overlooked.  We are using EPM to help standardize our environment and uncover problems, but sp_Blitz will definitely still help us out.  He even provides a cloud-based update feature, sp_BlitzUpdate, for sp_Blitz so you don’t have to constantly update it when he makes a change.  I think I’ll utilize his update code for some other challenges that we face at my work.

• JavaOne Latin America 2012 Trip Report

  - by reza_rahman

  JavaOne Latin America 2012 was held at the Transamerica Expo Center in Sao Paulo, Brazil on December 4-6. The conference was a resounding success with a great vibe, excellent technical content and numerous world class speakers. Some notable local and international speakers included Bruno Souza, Yara Senger, Mattias Karlsson, Vinicius Senger, Heather Vancura, Tori Wieldt, Arun Gupta, Jim Weaver, Stephen Chin, Simon Ritter and Henrik Stahl. Topics covered included the JCP/JUGs, Java SE 7, HTML 5/WebSocket, CDI, Java EE 6, Java EE 7, JSF 2.2, JMS 2, JAX-RS 2, Arquillian and JavaFX. Bruno Borges and I manned the GlassFish booth at the Java Pavilion on Tuesday and Webnesday. The booth traffic was decent and not too hectic. We met a number of GlassFish adopters including perhaps one of the largest GlassFish deployments in Brazil as well as some folks migrating to Java EE from Spring. We invited them to share their stories with us. We also talked with some key members of the local Java community. Tuesday evening we had the GlassFish party at the Tribeca Pub. The party was definitely a hit and we could have used a larger venue (this was the first time we had the GlassFish party in Brazil). Along with GlassFish enthusiasts, a number of Java community leaders were there. We met some of the same folks again at the JUG leader's party on Wednesday evening. On Thursday Arun Gupta, Bruno Borges and I ran a hands-on-lab on JAX-RS, WebSocket and Server-Sent Events (SSE) titled "Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket". This is the same Java EE 7 lab run at JavaOne San Francisco. The lab provides developers a first hand glipse of how an HTML 5 powered Java EE application might look like. We had an overflow crowd for the lab (at one point we had about twenty people standing) and the lab went very well. The slides for the lab are here: Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket from Reza Rahman The actual contents for the lab is available here. Give me a shout if you need help getting it up and running. I gave two solo talks following the lab. The first was on JMS 2 titled "What’s New in Java Message Service 2". This was essentially the same talk given by JMS 2 specification lead Nigel Deakin at JavaOne San Francisco. I talked about the JMS 2 simplified API, JMSContext injection, delivery delays, asynchronous send, JMS resource definition in Java EE 7, standardized configuration for JMS MDBs in EJB 3.2, mandatory JCA pluggability and the like. The session went very well, there was good Q & A and someone even told me this was the best session of the conference! The slides for the talk are here: What’s New in Java Message Service 2 from Reza Rahman My last talk for the conference was on JAX-RS 2 in the keynote hall. Titled "JAX-RS 2: New and Noteworthy in the RESTful Web Services API" this was basically the same talk given by the specification leads Santiago Pericas-Geertsen and Marek Potociar at JavaOne San Francisco. I talked about the JAX-RS 2 client API, asyncronous processing, filters/interceptors, hypermedia support, server-side content negotiation and the like. The talk went very well and I got a few very kind complements afterwards. The slides for the talk are here: JAX-RS 2: New and Noteworthy in the RESTful Web Services API from Reza Rahman On a more personal note, Sao Paulo has always had a special place in my heart as the incubating city for Sepultura and Soulfy -- two of my most favorite heavy metal musical groups of all time! Consequently, the city has a perpertually alive and kicking metal scene pretty much any given day of the week. This time I got to check out a solid performance by local metal gig Republica at the legendary Manifesto Bar. I also wanted to see a Dio Tribute at the Blackmore but ran out of time and energy... Overall I enjoyed the conference/Sao Paulo and look forward to going to Brazil again next year!

• 2014 Conferences - JFokus, JavaLand & GeeCon!

  - by Heather VanCura

  There has been a delay in publishing these past event summaries from early 2014--JFokus in February, JavaLand in March, and GeeCon in May. As we plan for Devoxx UK next week, I found these summaries that did not make it past 'draft' stage.  We had some great successes with the first three events of 2014, a Java developer conference trifecta! Participation topics included Java, the JCP program overall and the Adopt-a-JSR programs.   First up in February was JFokus in Stockholm. The energy and talent in Stockholm is amazing and the conference organizers do a stellar job running it and welcoming the speakers of this event.  I enjoyed the city walk and speaker dinner, as well as many opportunities to interact with conference speakers and attendees, both during and after the conference hours. Reza Rehman invited me to speak during his Java EE 7 lab session about the Adopt-a-JSR program, and I gave a quickie session on the JCP and Adopt-a-JSR.  There was also a late night Birds of a Feather (BoF) session held jointly with Cecelia Borg, Martijn Verburg and Reza Rehman.  This was an interactive conversation with a focus on the Java EE community survey results and encouraging more community participation and collaboration in Java development.  The Java 8 keynote by Georges Saab and Mark Reinhold was also very entertaining,  I was sorry to miss FOSDEM happening the previous weekend this year in Brussels, but I hope to attend in 2015.  Favorite take home gift -- Lambdas cap! In March, the inaugural version of the JavaLand conference happened inside Phantasialand, an amusement park in Germany. Markus Eisele suggested having an Early Adopters area at the conference, which I was keen to implement. In 2013 at Devoxx Belgium we held some activities in the Hackergaren area around Lambdas and Java EE 7, so this was a great opportunity to expand on a more interactive conference format and Andreas Badelt from the program committee helped in the planning for this area.  Daniel Bryant and Mani Sarkar from the London Java Community led some general Adopt-a-JSR discussions and AdoptOpen JDK activities.  JCP Spec Leads, Anatole Tresch from Credit Suisse, leading JSR 354, Money & Currency API, and Ed Burns from Oracle, leading JSR 344, JavaServer Faces 2.2, attended to engage with conference attendees on their JSRs.  Favorite - Stephen Chin's roller coaster video. In May, GeeCon in Krakow was anther awesome conference!  The conference organizers were warm and welcoming and I enjoyed time getting to know the other speakers at the event. There was a JCP and Adopt-a-JSR participation session as well as a moderated panel session on Early Adopters.  We had an amazing panel -- Daniel Bryant, Arun Gupta, Tomasz Borek , and Peter Lawrey. The panel discussed the Adopt-a-JSR and Adopt OpenJDK program, and how the participants work together to get involved and contribute to both the Java SE and Java EE platforms.  If was an interesting discussion and sparked some new ideas on how Java User Groups in Poland and around the world can contribute in a significant and meaningful way to create better and more practical Java standards today and in the future.  Favorite take home gift - GeeCon mug!   These were some of the highlights of the events--looking forward to Devoxx UK next week.  I will publish these details tomorrow!

• Standards Corner: Preventing Pervasive Monitoring

  - by independentid

   Phil Hunt is an active member of multiple industry standards groups and committees and has spearheaded discussions, creation and ratifications of industry standards including the Kantara Identity Governance Framework, among others. Being an active voice in the industry standards development world, we have invited him to share his discussions, thoughts, news & updates, and discuss use cases, implementation success stories (and even failures) around industry standards on this monthly column. Author: Phil Hunt On Wednesday night, I watched NBC’s interview of Edward Snowden. The past year has been tumultuous one in the IT security industry. There has been some amazing revelations about the activities of governments around the world; and, we have had several instances of major security bugs in key security libraries: Apple's ‘gotofail’ bug  the OpenSSL Heartbleed bug, not to mention Java’s zero day bug, and others. Snowden’s information showed the IT industry has been underestimating the need for security, and highlighted a general trend of lax use of TLS and poorly implemented security on the Internet. This did not go unnoticed in the standards community and in particular the IETF. Last November, the IETF (Internet Engineering Task Force) met in Vancouver Canada, where the issue of “Internet Hardening” was discussed in a plenary session. Presentations were given by Bruce Schneier, Brian Carpenter,  and Stephen Farrell describing the problem, the work done so far, and potential IETF activities to address the problem pervasive monitoring. At the end of the presentation, the IETF called for consensus on the issue. If you know engineers, you know that it takes a while for a large group to arrive at a consensus and this group numbered approximately 3000. When asked if the IETF should respond to pervasive surveillance attacks? There was an overwhelming response for ‘Yes'. When it came to 'No', the room echoed in silence. This was just the first of several consensus questions that were each overwhelmingly in favour of response. This is the equivalent of a unanimous opinion for the IETF. Since the meeting, the IETF has followed through with the recent publication of a new “best practices” document on Pervasive Monitoring (RFC 7258). This document is extremely sensitive in its approach and separates the politics of monitoring from the technical ones. Pervasive Monitoring (PM) is widespread (and often covert) surveillance through intrusive gathering of protocol artefacts, including application content, or protocol metadata such as headers. Active or passive wiretaps and traffic analysis, (e.g., correlation, timing or measuring packet sizes), or subverting the cryptographic keys used to secure protocols can also be used as part of pervasive monitoring. PM is distinguished by being indiscriminate and very large scale, rather than by introducing new types of technical compromise. The IETF community's technical assessment is that PM is an attack on the privacy of Internet users and organisations. The IETF community has expressed strong agreement that PM is an attack that needs to be mitigated where possible, via the design of protocols that make PM significantly more expensive or infeasible. Pervasive monitoring was discussed at the technical plenary of the November 2013 IETF meeting [IETF88Plenary] and then through extensive exchanges on IETF mailing lists. This document records the IETF community's consensus and establishes the technical nature of PM. The draft goes on to further qualify what it means by “attack”, clarifying that  The term is used here to refer to behavior that subverts the intent of communicating parties without the agreement of those parties. An attack may change the content of the communication, record the content or external characteristics of the communication, or through correlation with other communication events, reveal information the parties did not intend to be revealed. It may also have other effects that similarly subvert the intent of a communicator.  The past year has shown that Internet specification authors need to put more emphasis into information security and integrity. The year also showed that specifications are not good enough. The implementations of security and protocol specifications have to be of high quality and superior testing. I’m proud to say Oracle has been a strong proponent of this, having already established its own secure coding practices.

• BizTalk: Instance Subscription: Details

  - by Leonid Ganeline

  It has interesting behavior and it is not always what we are waiting for. An orchestration can be enlisted with many subscriptions. In other word it can have several Receive shapes. Usually the first Receive uses the Activation subscription but other Receives create the Instance subscriptions. [See “Publish and Subscribe Architecture” in MSDN] Here is a sample process. This orchestration has two receives. It is a typical Sequential Convoy. [See "BizTalk Server 2004 Convoy Deep Dive" in MSDN by Stephen W. Thomas]. Let's experiment started.   There are three typical scenarios. First scenario: everything is OK Activation subscription for the Sample message is created when the orchestration the SampleProcess is enlisted. The Instance subscription is created only when the SampleProcess orchestration instance is started and it is removed when the orchestration instance is ended. So far so good, the Message_2 was delivered exactly in this time interval and was consumed. Second scenario: no consumers Three Sample_2 messages were delivered. One was delivered before the SampleProcess was started and before the instance subscription was created. Second message was delivered in the correct time interval. The third one was delivered after the SampleProcess orchestration was ended and the instance subscription was removed. Note: ·         It was not the first Sample_2 was consumed. It was first in the queue but in was not waiting, it was suspended when it was delivered to the Message Box and didn’t have any subscribers at this moment. The first and the last Sample_2 messages were Suspended (Nonresumable) in the Message Box. For each of this message we have got two (!) service instances associated with this suspended message. One service instance has the ServiceClass of Messaging, and we can see its Error Description:   The second service instance has the ServiceClass of RoutingFailureReport, and we can see its Error Description:   Third scenario: something goes wrong Two Sample_2 messages were delivered. Both were delivered in the same interval when the SampleProcess orchestration was working and the instance subscription was created and was working too. First Sample_2 was consumed. The second Sample_2 has the subscription but the subscriber, the SampleProcess orchestration, will not consume it. After the SampleProcess orchestration is ended (And only after! I will discuss this in the next article.), it is suspended (Nonresumable). In this time only one service instance associated with this kind of scenario is suspended. This service instance has the ServiceClass of Orchestration, and we can see its Error Description: In the Message tab we will see the Sample_2 message in the Suspended (Resumable) status. Note: ·         This behavior looks ambiguous. We see here the orchestration consumes the extra message(s) and gets suspended together with those extra messages. These messages are not consumed in term of “processed by orchestration”. But they are consumed in term of the “delivered to the subscriber”. The receive shape in the orchestration is not received these extra messages. But these messages are routed to the orchestration.     Unified Sequential convoy  Now one more scenario. It is the unified sequential convoy. That means the activation subscription is for the same message type as it for the instance subscription. The Sample_2 message is now the Sample message. For simplicity the SampleProcess orchestration consumes only two Sample messages. Usually the orchestration consumes a lot of messages inside loop, but now it is only two of them. First message starts the orchestration, the second message goes inside this orchestration. Then the next pair of messages follows, and so on. But if the input messages follow in shorter intervals we have got the problem. We lost messages in unpredictable manner. Note: ·         Maybe the better behavior would be if the orchestration removes the instance subscription after the message is consumed, not in the end on the orchestration. Right now it is a “feature” of the BizTalk subscription mechanism.
