• SQL SERVER – Beginning of SQL Server Architecture – Terminology – Guest Post

  - by pinaldave

  SQL Server Architecture is a very deep subject. Covering it in a single post is an almost impossible task. However, this subject is very popular topic among beginners and advanced users.  I have requested my friend Anil Kumar who is expert in SQL Domain to help me write  a simple post about Beginning SQL Server Architecture. As stated earlier this subject is very deep subject and in this first article series he has covered basic terminologies. In future article he will explore the subject further down. Anil Kumar Yadav is Trainer, SQL Domain, Koenig Solutions. Koenig is a premier IT training firm that provides several IT certifications, such as Oracle 11g, Server+, RHCA, SQL Server Training, Prince2 Foundation etc. In this Article we will discuss about MS SQL Server architecture. The major components of SQL Server are: Relational Engine Storage Engine SQL OS Now we will discuss and understand each one of them. 1) Relational Engine: Also called as the query processor, Relational Engine includes the components of SQL Server that determine what your query exactly needs to do and the best way to do it. It manages the execution of queries as it requests data from the storage engine and processes the results returned. Different Tasks of Relational Engine: Query Processing Memory Management Thread and Task Management Buffer Management Distributed Query Processing 2) Storage Engine: Storage Engine is responsible for storage and retrieval of the data on to the storage system (Disk, SAN etc.). to understand more, let’s focus on the following diagram. When we talk about any database in SQL server, there are 2 types of files that are created at the disk level – Data file and Log file. Data file physically stores the data in data pages. Log files that are also known as write ahead logs, are used for storing transactions performed on the database. Let’s understand data file and log file in more details: Data File: Data File stores data in the form of Data Page (8KB) and these data pages are logically organized in extents. Extents: Extents are logical units in the database. They are a combination of 8 data pages i.e. 64 KB forms an extent. Extents can be of two types, Mixed and Uniform. Mixed extents hold different types of pages like index, System, Object data etc. On the other hand, Uniform extents are dedicated to only one type. Pages: As we should know what type of data pages can be stored in SQL Server, below mentioned are some of them: Data Page: It holds the data entered by the user but not the data which is of type text, ntext, nvarchar(max), varchar(max), varbinary(max), image and xml data. Index: It stores the index entries. Text/Image: It stores LOB ( Large Object data) like text, ntext, varchar(max), nvarchar(max),  varbinary(max), image and xml data. GAM & SGAM (Global Allocation Map & Shared Global Allocation Map): They are used for saving information related to the allocation of extents. PFS (Page Free Space): Information related to page allocation and unused space available on pages. IAM (Index Allocation Map): Information pertaining to extents that are used by a table or index per allocation unit. BCM (Bulk Changed Map): Keeps information about the extents changed in a Bulk Operation. DCM (Differential Change Map): This is the information of extents that have modified since the last BACKUP DATABASE statement as per allocation unit. Log File: It also known as write ahead log. It stores modification to the database (DML and DDL). Sufficient information is logged to be able to: Roll back transactions if requested Recover the database in case of failure Write Ahead Logging is used to create log entries Transaction logs are written in chronological order in a circular way Truncation policy for logs is based on the recovery model SQL OS: This lies between the host machine (Windows OS) and SQL Server. All the activities performed on database engine are taken care of by SQL OS. It is a highly configurable operating system with powerful API (application programming interface), enabling automatic locality and advanced parallelism. SQL OS provides various operating system services, such as memory management deals with buffer pool, log buffer and deadlock detection using the blocking and locking structure. Other services include exception handling, hosting for external components like Common Language Runtime, CLR etc. I guess this brief article gives you an idea about the various terminologies used related to SQL Server Architecture. In future articles we will explore them further. Guest Author  The author of the article is Anil Kumar Yadav is Trainer, SQL Domain, Koenig Solutions.

• Social Network Updates: While You Were Busy Marketing 2

  - by Mike Stiles

  Since social moves at the speed of data, it’s already time for another update, as we did back in April, on the changes the various social networks have made or gone through while you were busy marketing. Facebook There’s a lot of talk Facebook’s developing a mobile product to act like Flipboard and surface news, from both users and media outlets. The biggest news was Facebook/Instagram’s introduction of 15-second videos, enhanced with with filters, to take some of Vine’s candy. You can also delete parts of videos and rerecord them, and there’s image stabilization. Facebook’s ad revenue is coming along just fine, thank you very much. 35% quarter-to-quarter growth in Q2. And it looks like new formats like Mobile App Install Ads and Unpublished Page Posts are adding to the mix. If you don’t already, you’ll soon see a little camera in comment boxes letting you insert photos right into the comments you make. The drive toward “more visual” continues. The other big news is Facebook’s adoption of our Twitter friend, the hashtag. Adding # sets apart the post topic so it can be easily found or discovered. It’s also being added to Google Plus, Tumblr, and Pinterest. Twitter Want to send someone a promoted tweet when they’re in range of your store? That could be happening by the end of this year. Some users have been seeing automatic in-stream previews of images on Twitter.com. Right now it’s images in your own tweets, but we can assume all tweets are next. Get your followers organized! Twitter raised the limit on the number of lists you can create from 20 to 1,000. They also raised the number of accounts you can have in a list from 500 to 5,000. Twitter started notifying you when someone favorites a tweet you’re mentioned in or re-tweets a tweet you re-tweeted. Anyway, it’s the first time Twitter’s notified you about indirect interactions like that. Who’s afraid of Instagram? A study shows 6-second Vine videos are being posted to Twitter at the rate of 9/second, up from 5/second 2 months ago. Vine has over 13 million users and branded Vines are 4x more likely to be shared than video ads. Google Plus Now featuring a 3-column redesigned stream, and images that take up a whole column. And photo filters Auto Highlight and Auto Awesome work to turn your photos into a real show. Google Hangouts is the workhorse for all Google messaging now, it’s not just an online chat with 9 people anymore. Google Plus Dashboard improves the connection between your company’s Google Plus business page and your Google Plus Local. Updates go out across all Google properties and you can do your managing from the dashboard. With Google Plus’ authorship system, you can build “Author Rank” based on what you write and put on the web. If your stuff is +1’ed and shared a lot, you’re the real deal and there are search result benefits. LinkedIn "Who's Viewed Your Updates" shows you what you’ve shared recently, who saw it and what they did about it in real-time. “Influencers” is, well, influential. Traffic to all LI news products has gone up 8x since it was introduced. LinkedIn is quickly figuring out how to get users to stick around awhile. You and your brand can post images and documents in status updates now. In fact, that whole “document posting” thing is making some analysts wonder if LinkedIn will drift on over to the Dropboxes and YouSendIts of the world. C’mon, admit it. Your favorite part of LinkedIn is being able to see who’s viewed your profile. Now you’ve got even more info and can see what/who you have in common. Premium users get even deeper insights about how people are finding them. If you’re a big fan of security, you’ll love that LinkedIn started offering two-factor authentication (2FA). It’s optional, but step 2 is a one-time code texted to your registered mobile. Pinterest A study showed pins have a looong shelf life compared to other social net posts. “Clicks kept coming for 30 days and beyond.” Most pins are timeless, and the infinite scroll causes people to see older pins. Is it a keeper? Pinterest jumped 82% to 54 million users in the past year. It’s valued at $2.5 billion and is one of the biggest sources of referral traffic there is. That said, CEO Ben Silbermann adds, "Right now, we don't make money." A new search feature stops you from having to endlessly scroll through your own pins looking for that waterfall picture you posted. Simply select “just my pins” in the search bar. New "Rich Pins" lets brands add info like price and availability to pins that can be updated daily via a data feed from your merchant site. Not so fast, you have to apply to Pinterest for it first. Like other social nets, Pinterest does not allow sexual content, nudity, or even partial nudity. However…some art contains nudity, and Pinterest wants to allow art. What constitutes “art” will be judged by…what we have to assume are Pinterest employees who love their job. @mikestilesPhoto: stock.xchng, Tim Marmon

• Getting the innermost .NET Exception

  - by Rick Strahl

  Here's a trivial but quite useful function that I frequently need in dynamic execution of code: Finding the innermost exception when an exception occurs, because for many operations (for example Reflection invocations or Web Service calls) the top level errors returned can be rather generic. A good example - common with errors in Reflection making a method invocation - is this generic error: Exception has been thrown by the target of an invocation In the debugger it looks like this: In this case this is an AJAX callback, which dynamically executes a method (ExecuteMethod code) which in turn calls into an Amazon Web Service using the old Amazon WSE101 Web service extensions for .NET. An error occurs in the Web Service call and the innermost exception holds the useful error information which in this case points at an invalid web.config key value related to the System.Net connection APIs. The "Exception has been thrown by the target of an invocation" error is the Reflection APIs generic error message that gets fired when you execute a method dynamically and that method fails internally. The messages basically says: "Your code blew up in my face when I tried to run it!". Which of course is not very useful to tell you what actually happened. If you drill down the InnerExceptions eventually you'll get a more detailed exception that points at the original error and code that caused the exception. In the code above the actually useful exception is two innerExceptions down. In most (but not all) cases when inner exceptions are returned, it's the innermost exception that has the information that is really useful. It's of course a fairly trivial task to do this in code, but I do it so frequently that I use a small helper method for this: /// <summary> /// Returns the innermost Exception for an object /// </summary> /// <param name="ex"></param> /// <returns></returns> public static Exception GetInnerMostException(Exception ex) { Exception currentEx = ex; while (currentEx.InnerException != null) { currentEx = currentEx.InnerException; } return currentEx; } This code just loops through all the inner exceptions (if any) and assigns them to a temporary variable until there are no more inner exceptions. The end result is that you get the innermost exception returned from the original exception. It's easy to use this code then in a try/catch handler like this (from the example above) to retrieve the more important innermost exception: object result = null; string stringResult = null; try { if (parameterList != null) // use the supplied parameter list result = helper.ExecuteMethod(methodToCall,target, parameterList.ToArray(), CallbackMethodParameterType.Json,ref attr); else // grab the info out of QueryString Values or POST buffer during parameter parsing // for optimization result = helper.ExecuteMethod(methodToCall, target, null, CallbackMethodParameterType.Json, ref attr); } catch (Exception ex) { Exception activeException = DebugUtils.GetInnerMostException(ex); WriteErrorResponse(activeException.Message, ( HttpContext.Current.IsDebuggingEnabled ? ex.StackTrace : null ) ); return; } Another function that is useful to me from time to time is one that returns all inner exceptions and the original exception as an array: /// <summary> /// Returns an array of the entire exception list in reverse order /// (innermost to outermost exception) /// </summary> /// <param name="ex">The original exception to work off</param> /// <returns>Array of Exceptions from innermost to outermost</returns> public static Exception[] GetInnerExceptions(Exception ex) {     List<Exception> exceptions = new List<Exception>();     exceptions.Add(ex);       Exception currentEx = ex;     while (currentEx.InnerException != null)     {         exceptions.Add(ex);     }       // Reverse the order to the innermost is first     exceptions.Reverse();       return exceptions.ToArray(); } This function loops through all the InnerExceptions and returns them and then reverses the order of the array returning the innermost exception first. This can be useful in certain error scenarios where exceptions stack and you need to display information from more than one of the exceptions in order to create a useful error message. This is rare but certain database exceptions bury their exception info in mutliple inner exceptions and it's easier to parse through them in an array then to manually walk the exception stack. It's also useful if you need to log errors and want to see the all of the error detail from all exceptions. None of this is rocket science, but it's useful to have some helpers that make retrieval of the critical exception info trivial.

• Nerdstock 2012: A photo review of Microsoft TechEd North America 2012

  - by The Un-T Guy

  Not only could I not fathom that I would ever be attending a tech event of the magnitude of TechEd, neither could any of my co-workers.  As the least technical person in the history of Information Technology ever, I felt as though I were walking into the belly of the beast, fearing I’d not be allowed out until I could write SSIS packages, program in Visual Basic, or at least arm wrestle a DBA.  Most of my fears were unrealized.   But I made it.  I was here.  I even got to wear the Mark of the Geek neck package with schedule, eyeglass cleaners, name badge (company name obfuscated so they don’t fire me), and a pen.  The name  badge was seemingly the key element, as every vendor in the place wanted to scan it to capture name, email address, and numbers to show their bosses back home.  It also let me eat the food and drink the coffee so that’s a fair trade.   A recurring theme throughout the presentations and vendor demos was “the Cloud” and BYOD (bring your own device).  The below was a common site throughout the week, as attendees from all over the world brought their own devices and were able to (seemingly) seamlessly connect to the Worldwide Innerwebs.  Apparently proof that Microsoft and the event organizers were practicing what they were preaching.   “Cavernous” is one way to describe the downstairs facility itself.  “Freaking cavernous” might be more accurate.  Work sessions were held in classrooms on the second and third floors but the real action was happening downstairs.  Microsoft bookstore, blogger hub (shoutout to Geekswithblogs.net), The Wall (sans Pink Floyd, sadly), couches, recharging stations…   …a game zone with pool and air hockey tables, pinball machines, foosball…   …vintage video games…           …and a even giant chess board.  Looked like this guy was opening with the Kaspersky parry.   The blend of technology and fantasy even went so far as to bring childhood favorites to life.  Assuming, of course, your childhood was pre-video games (like mine) and you were stuck with electric football and Rock ‘em Sock ‘em robots:   And, lest the “combatants” become unruly or – God forbid – afternoon snacks were late, Orange County’s finest was on the scene to keep the peace.  On a high-tech mode of transport, of course.   She wasn’t the only one to think this was a swell way to transition from one concourse to the next.  Given the level of support provided by the entire Orange County Convention Center staff, I knew they had to have some secret.   Here’s one entrance to the vendor zone/”Technical Learning Center.”  Couldn’t help but think of them as the remora attached to the Whale Shark that is Microsoft…   …or perhaps planets orbiting the sun. Microsoft is just that huge and it seemed like every vendor in the industry looks forward to partnering with the tech behemoth.   Aside from the free stuff from the vendors, probably the most popular place in the house was the dining area.  Amazing spreads every day, multiple times a day.  While no attendance numbers were available at press time, literally thousands of attendees were fed, and fed well, every day.  And lest you think my post from earlier in the week exaggerated about the backpacks…   …or that I’m exaggerating about the lunch crowds.  This represents only about between 25-30% of the lunch crowd – it was all my camera could capture at once.  No one went away hungry.   The only thing missing was a a vat of Red Bull but apparently organizers went old school, with probably 100 urns of the original energy drink – coffee – all around the venue.   Of course, following lunch and afternoon sessions, some preferred the even older school method of re-energizing.  There were rumors that Microsoft was serving graham crackers and milk in this area.  But they were only rumors.   Cannot overstate the wonderful service provided by the Orange County Convention Center staff.  Coffee, soft drinks, juice, and water were available always.  Buffet meals were delicious with a wide range of healthy options available, in addition to hundreds (at least) special meal requests supported every day.  Ever tried to keep up with an estimated 9,000 hungry and thirsty IT-ers?  These folks did.  Kudos to all of the staff and many thanks!   And while I occasionally poke fun at the Whale Shark, if nothing else this experience convinced me of one thing:  Microsoft knows how to put on a professional event.  Hundreds of informative, professionally delivered sessions, covering a wide range of topics set at varying levels of expertise (some that even I was able to follow), social activities, vendor partnerships…they brought everything you could ask for to inform, educate, and inspire an entire IT industry.   So as I depart the belly of the beast, I can both take pride in the fact that I survived the week and marvel at the brilliance surrounding me.  The IT industry – or at least the segment associated with Microsoft – is in good, professional hands.  And what won’t fit in their hands can be toted in the Microsoft provided backpacks.  Win-win.   Until New Orleans…

• Using LogParser - part 2

  - by fatherjack

  PersonAddress.csv SalesOrderDetail.tsv In part 1 of this series we downloaded and installed LogParser and used it to list data from a csv file. That was a good start and in this article we are going to see the different ways we can stream data and choose whether a whole file is selected. We are also going to take a brief look at what file types we can interrogate. If we take the query from part 1 and add a value for the output parameter as -o:datagrid so that the query becomes LOGPARSER "SELECT top 15 * FROM C:\LP\person_address.csv" -o:datagrid and run that we get a different result. A pop-up dialog that lets us view the results in a resizable grid. Notice that because we didn't specify the columns we wanted returned by LogParser (we used SELECT *) is has added two columns to the recordset - filename and rownumber. This behaviour can be very useful as we will see in future parts of this series. You can click Next 10 rows or All rows or close the datagrid once you are finished reviewing the data. You may have noticed that the files that I am working with are different file types - one is a csv (comma separated values) and the other is a tsv (tab separated values). If you want to convert a file from one to another then LogParser makes it incredibly simple. Rather than using 'datagrid' as the value for the output parameter, use 'csv': logparser "SELECT SalesOrderID, SalesOrderDetailID, CarrierTrackingNumber, OrderQty, ProductID, SpecialOfferID, UnitPrice, UnitPriceDiscount, LineTotal, rowguid, ModifiedDate into C:\Sales_SalesOrderDetail.csv FROM C:\Sales_SalesOrderDetail.tsv" -i:tsv -o:csv Those familiar with SQL will not have to make a very big leap of faith to making adjustments to the above query to filter in/out records from the source file. Lets get all the records from the same file where the Order Quantity (OrderQty) is more than 25: logparser "SELECT SalesOrderID, SalesOrderDetailID, CarrierTrackingNumber, OrderQty, ProductID, SpecialOfferID, UnitPrice, UnitPriceDiscount, LineTotal, rowguid, ModifiedDate into C:\LP\Sales_SalesOrderDetailOver25.csv FROM C:\LP\Sales_SalesOrderDetail.tsv WHERE orderqty > 25" -i:tsv -o:csv Or we could find all those records where the Order Quantity is equal to 25 and output it to an xml file: logparser "SELECT SalesOrderID, SalesOrderDetailID, CarrierTrackingNumber, OrderQty, ProductID, SpecialOfferID, UnitPrice, UnitPriceDiscount, LineTotal, rowguid, ModifiedDate into C:\LP\Sales_SalesOrderDetailEq25.xml FROM C:\LP\Sales_SalesOrderDetail.tsv WHERE orderqty = 25" -i:tsv -o:xml All the standard comparison operators are to be found in LogParser; >, <, =, LIKE, BETWEEN, OR, NOT, AND. Input and Output file formats. LogParser has a pretty impressive list of file formats that it can parse and a good selection of output formats that will let you generate output in a format that is useable for whatever process or application you may be using. From any of these To any of these IISW3C: parses IIS log files in the W3C Extended Log File Format.   NAT: formats output records as readable tabulated columns. IIS: parses IIS log files in the Microsoft IIS Log File Format. CSV: formats output records as comma-separated values text. BIN: parses IIS log files in the Centralized Binary Log File Format. TSV: formats output records as tab-separated or space-separated values text. IISODBC: returns database records from the tables logged to by IIS when configured to log in the ODBC Log Format. XML: formats output records as XML documents. HTTPERR: parses HTTP error log files generated by Http.sys. W3C: formats output records in the W3C Extended Log File Format. URLSCAN: parses log files generated by the URLScan IIS filter. TPL: formats output records following user-defined templates. CSV: parses comma-separated values text files. IIS: formats output records in the Microsoft IIS Log File Format. TSV: parses tab-separated and space-separated values text files. SQL: uploads output records to a table in a SQL database. XML: parses XML text files. SYSLOG: sends output records to a Syslog server. W3C: parses text files in the W3C Extended Log File Format. DATAGRID: displays output records in a graphical user interface. NCSA: parses web server log files in the NCSA Common, Combined, and Extended Log File Formats. CHART: creates image files containing charts. TEXTLINE: returns lines from generic text files. TEXTWORD: returns words from generic text files. EVT: returns events from the Windows Event Log and from Event Log backup files (.evt files). FS: returns information on files and directories. REG: returns information on registry values. ADS: returns information on Active Directory objects. NETMON: parses network capture files created by NetMon. ETW: parses Enterprise Tracing for Windows trace log files and live sessions. COM: provides an interface to Custom Input Format COM Plugins. So, you can query data from any of the types on the left and really easily get it into a format where it is ready for analysis by other tools. To a DBA or network Administrator with an enquiring mind this is a treasure trove. In part 3 we will look at working with multiple sources and specifically outputting to SQL format. See you there!

• Installing SOA Suite 11.1.1.3

  - by James Taylor

  With the release of Oracle SOA Suite 11.1.1.3 last week (28 April 2010) I thought I would attempt to implement a complete SOA Environment with SOA Suite, BPM and OSB on the WLS infrastructure. One major point of difference with the 11.1.1.3 is that is is released as a point release so you must have 11.1.1.2 installed first, then upgrade to 11.1.1.3. This post is performing the upgrade on Linux, if upgrading on windows you will need to substitute the directories and files accordingly. This post assumes that you have SOA Suite 11.1.1.2 installed already. 1. Download 11.1.1.3 software from the following site: http://www.oracle.com/technology/software/products/middleware/htdocs/fmw_11_download.html WLS 11.1.1.3   RCU 11.1.1.3 SOA Suite 11.1.1.3 OSB 11.1.1.3 Copy files to a staging area. For the purpose of this document the staging area is: /u01/stage  2. Shutdown your existing SOA Suite 11.1.1.2 environment 3. Execute the WLS 11.1.1.3 install from the stage directory. wls1033_linux32.bin 4. Choose the existing 11.1.1.2 Middleware Home 5. Ignore the security update notification 6. Accept the default products to be upgraded. 7. Upgrade of WebLogic has been completed   8. Upgrade the SOA Suite database schemas using the RCU utility. Unzip the RCU utility into the staging area and run the install ./u01/stage/rcuHome/bin/rcu 9. Drop the existing Repository and provide connection details 9. Install SOA Suite patch set 11.1.1.3. Unzip the SOA Suite patchset and execute the runInstaller with the following command. ./u01/stage/Disk1/runInstaller –jreLoc $MW_HOME/jdk160_18/jre 10. Choose the existing 11.1.1.2 middleware home 11. Start Install 12. Your SOA Suite Install should now be completed. Now we need to update the database repository. Login to SQLPlus as sysdba and execute the following command. SELECT version, status FROM schema_version_registry where owner = 'DEV_SOAINFRA'; the result should be similar to this: VERSION                        STATUS      OWNER ------------------------------ ----------- ------------------------------ 11.1.1.2.0                     VALID       DEV_SOAINFRA As you can see the version if these repositories are still at 11.1.1.2. 13. To upgrade these versions you have 2 options. 1 install via RCU, but this will remove any existing services. The second option is to use the Patch Set Assistant. From the $MW_HOME directory run the following command ./Oracle_SOA1/bin/psa -dbType Oracle -dbConnectString 'localhost:1521:xe' -dbaUserName sys -schemaUserName DEV_SOAINFRA 14. Install OSB. For the OSB install I did not install the IDE, or the Examples. run the runInstaller from the command line, unzip the OSB download to the stage area. ./u01/stage/osb/Disk1/runInstaller –jreLoc $MW_HOME/jdk160_18/jre 15. Choose Custom Install NOT to install the IDE (Eclipse) or Examples. 16. Unselect the, Examples and IDE checkboxes. 17. Accept the defaults and start installing. 18. Once the install has been completed configure the domain by running the Configuration Wizard. $MW_HOME/oracle_common/common/bin/config.sh You can create a new domain. In this document I will extend the soa_domain. 19. Select the following from the check list. I have selected the BPM Suite, this is unrelated to OSB but wanted it for my development purposes. To use this functionality additional license are required. 20. Configure the database connectivity. 21. Configure the database connectivity for the OSB schema. 22. Accept the defaults if installing on standard machine, if you require a cluster or advanced configuration then choose the option for you. 23. Upgrade is complete and OSB has been installed. Now you can start your environment.

• Why Software Sucks...and What You Can Do About It – book review

  - by DigiMortal

      How do our users see the products we are writing for them and how happy they are with our work? Are they able to get their work done without fighting with cool features and crashes or are they just switching off resistance part of their brain to survive our software? Yeah, the overall picture of software usability landscape is not very nice. Okay, it is not even nice. But, fortunately, Why Software Sucks...and What You Can Do About It by David S. Platt explains everything. Why Software Sucks… is book for software users but I consider it as a-must reading also for developers and specially for their managers whose politics often kills all usability topics as soon as they may appear. For managers usability is soft topic that can be manipulated the way it is best in current state of project. Although developers are not UI designers and usability experts they are still very often forced to deal with these topics and this is how usability problems start (of course, also designers are able to produce designs that are stupid and too hard to use for users, but this blog here is about development). I found this book to be very interesting and funny reading. It is not humor book but it explains you all so you remember later very well what you just read. It took me about three evenings to go through this book and I am still enjoying what I found and how author explains our weird young working field to end users. I suggest this book to all developers – while you are demanding your management to hire or outsource usability expert you are at least causing less pain to end users. So, go and buy this book, just like I did. And… they thanks to mr. Platt :) There is one book more I suggest you to read if you are interested in usability - Don't Make Me Think: A Common Sense Approach to Web Usability, 2nd Edition by Steve Krug. Editorial review from Amazon Today’s software sucks. There’s no other good way to say it. It’s unsafe, allowing criminal programs to creep through the Internet wires into our very bedrooms. It’s unreliable, crashing when we need it most, wiping out hours or days of work with no way to get it back. And it’s hard to use, requiring large amounts of head-banging to figure out the simplest operations. It’s no secret that software sucks. You know that from personal experience, whether you use computers for work or personal tasks. In this book, programming insider David Platt explains why that’s the case and, more importantly, why it doesn’t have to be that way. And he explains it in plain, jargon-free English that’s a joy to read, using real-world examples with which you’re already familiar. In the end, he suggests what you, as a typical user, without a technical background, can do about this sad state of our software—how you, as an informed consumer, don’t have to take the abuse that bad software dishes out. As you might expect from the book’s title, Dave’s expose is laced with humor—sometimes outrageous, but always dead on. You’ll laugh out loud as you recall incidents with your own software that made you cry. You’ll slap your thigh with the same hand that so often pounded your computer desk and wished it was a bad programmer’s face. But Dave hasn’t written this book just for laughs. He’s written it to give long-overdue voice to your own discovery—that software does, indeed, suck, but it shouldn’t.

• Big Data – Buzz Words: Importance of Relational Database in Big Data World – Day 9 of 21

  - by Pinal Dave

  In yesterday’s blog post we learned what is HDFS. In this article we will take a quick look at the importance of the Relational Database in Big Data world. A Big Question? Here are a few questions I often received since the beginning of the Big Data Series - Does the relational database have no space in the story of the Big Data? Does relational database is no longer relevant as Big Data is evolving? Is relational database not capable to handle Big Data? Is it true that one no longer has to learn about relational data if Big Data is the final destination? Well, every single time when I hear that one person wants to learn about Big Data and is no longer interested in learning about relational database, I find it as a bit far stretched. I am not here to give ambiguous answers of It Depends. I am personally very clear that one who is aspiring to become Big Data Scientist or Big Data Expert they should learn about relational database. NoSQL Movement The reason for the NoSQL Movement in recent time was because of the two important advantages of the NoSQL databases. Performance Flexible Schema In personal experience I have found that when I use NoSQL I have found both of the above listed advantages when I use NoSQL database. There are instances when I found relational database too much restrictive when my data is unstructured as well as they have in the datatype which my Relational Database does not support. It is the same case when I have found that NoSQL solution performing much better than relational databases. I must say that I am a big fan of NoSQL solutions in the recent times but I have also seen occasions and situations where relational database is still perfect fit even though the database is growing increasingly as well have all the symptoms of the big data. Situations in Relational Database Outperforms Adhoc reporting is the one of the most common scenarios where NoSQL is does not have optimal solution. For example reporting queries often needs to aggregate based on the columns which are not indexed as well are built while the report is running, in this kind of scenario NoSQL databases (document database stores, distributed key value stores) database often does not perform well. In the case of the ad-hoc reporting I have often found it is much easier to work with relational databases. SQL is the most popular computer language of all the time. I have been using it for almost over 10 years and I feel that I will be using it for a long time in future. There are plenty of the tools, connectors and awareness of the SQL language in the industry. Pretty much every programming language has a written drivers for the SQL language and most of the developers have learned this language during their school/college time. In many cases, writing query based on SQL is much easier than writing queries in NoSQL supported languages. I believe this is the current situation but in the future this situation can reverse when No SQL query languages are equally popular. ACID (Atomicity Consistency Isolation Durability) – Not all the NoSQL solutions offers ACID compliant language. There are always situations (for example banking transactions, eCommerce shopping carts etc.) where if there is no ACID the operations can be invalid as well database integrity can be at risk. Even though the data volume indeed qualify as a Big Data there are always operations in the application which absolutely needs ACID compliance matured language. The Mixed Bag I have often heard argument that all the big social media sites now a days have moved away from Relational Database. Actually this is not entirely true. While researching about Big Data and Relational Database, I have found that many of the popular social media sites uses Big Data solutions along with Relational Database. Many are using relational databases to deliver the results to end user on the run time and many still uses a relational database as their major backbone. Here are a few examples: Facebook uses MySQL to display the timeline. (Reference Link) Twitter uses MySQL. (Reference Link) Tumblr uses Sharded MySQL (Reference Link) Wikipedia uses MySQL for data storage. (Reference Link) There are many for prominent organizations which are running large scale applications uses relational database along with various Big Data frameworks to satisfy their various business needs. Summary I believe that RDBMS is like a vanilla ice cream. Everybody loves it and everybody has it. NoSQL and other solutions are like chocolate ice cream or custom ice cream – there is a huge base which loves them and wants them but not every ice cream maker can make it just right  for everyone’s taste. No matter how fancy an ice cream store is there is always plain vanilla ice cream available there. Just like the same, there are always cases and situations in the Big Data’s story where traditional relational database is the part of the whole story. In the real world scenarios there will be always the case when there will be need of the relational database concepts and its ideology. It is extremely important to accept relational database as one of the key components of the Big Data instead of treating it as a substandard technology. Ray of Hope – NewSQL In this module we discussed that there are places where we need ACID compliance from our Big Data application and NoSQL will not support that out of box. There is a new termed coined for the application/tool which supports most of the properties of the traditional RDBMS and supports Big Data infrastructure – NewSQL. Tomorrow In tomorrow’s blog post we will discuss about NewSQL.

• How to create a new Team Project Collection in TFS2010:

  - by jehan

  TFS 2010 has introduced the notion of Team Project Collection (TPC).  I have already discussed about TPC in my earlier post, you can check it out here. In this post, I will demonstrate how to create a new Team Project Collection in TFS2010. First, you have to open the TFS Administration Console (Start à All Programs à Microsoft Team Foundation Server 2010 à Team Foundation Server Administration Console), expand the Application Tier node in TFS Administration Console and click on Team Project Collection. Here you will see the TPC’s which are already exist, I am having only one TPC named New Collection and I’m going to create a new TPC called Demo Collection. To create a new Team Project Collection, you need to click on Create Collection; it will open the Create New Team Project Collection window.     Under the Name tab, you have to enter the name of Collection which you want to give for your new TPC (I naming it as Demo Collection). You can also provide some description about your TPC in Description tab which is optional and click next. Here, you need to enter the name of SQL Server Instance where you want your new TPC data to reside. You have the option either to choose the creating a Database for this TPC or use the already existing empty database and then click next.   In next screen, you have to choose SharePoint configuration. Here you have the options to either configure SharePoint Site for TPC at default collections or you can specify the your existing SharePoint site and  you can also choose not  to configure the SharePoint for this collection, if you choose last option then you cannot configure the Share Point sites for the all the Team Projects under this Project Collection. You also have the flexibility to create a Share Point site for this TPC later on, then if you need you have to configure SharePoint site for the existing team projects manually.   In next screen, you will have the Reports configuration. Here you have the options to either configure the Reports for TPC at default path or you can specify the path for at existing Reports folder, you can also choose not to configure the Reports for this collection, if you choose last option then you cannot create  the Reports  for the all the Team Projects under this Project Collection. Here also you can enable reporting for this TPC later on. The next screen is related to Lab Management Configuration, Lab Management is the new feature in TFS2010 which enables the users to create and manage virtual test environments where you can deploy and test your application. There are no options available here as I don’t have the Lab Management configured for my Team Foundation Server. The next screen is Review Configuration window, which will show up all the configuration settings you have specified, so that you can review the configurations before creating the Team Project Collection. If you want to make any changes to the configurations then you can go back to the previous windows and can make the changes. After Reviewing the configuration settings, you can click on verify button. Which will verify that if you’re Team Project Collection is ready to be created or not, it will show up the errors and warning (if any) which can make your Team Project Collection fail. You can then choose to create the Team Project Collection if the verify option doesn’t throw any warnings and errors. If the verify option throws any errors, then it is strongly suggested that you have to first rectify the issues then only go for TPC creation especially in case of warnings as it is a common practice to overlook the warnings.   If you choose the create TPC option, then it will start the process of creating a Team Project Collection  and once its completed you can check the status of configuration different components  during Team Project Collection. You can see in below screen that all the components are configured successfully.   In next screen, you can find the location of log file created for this Team Project Creation, this log file is really important in case of Team Project creation failure because it will help you to find  the root cause for the failure. Now, you can see that the New Team Projection (Demo Collection) which was created is now available in Team Foundation Collection tab and its status is Online.   You can now try to connect to this Team Project Collection from Team Explorer. Choose the newly created Team Project Collection and click on connect.     This Team Project Collection is empty because no Team Projects are created yet. Now, you can create the new Team Projects and start working.

• Clean Up the New Ubuntu Grub2 Boot Menu

  - by Trevor Bekolay

  Ubuntu adopted the new version of the Grub boot manager in version 9.10, getting rid of the old problematic menu.lst. Today we look at how to change the boot menu options in Grub2. Grub2 is a step forward in a lot of ways, and most of the annoying menu.lst issues from the past are gone. Still, if you’re not vigilant with removing old versions of the kernel, the boot list can still end up being longer than it needs to be. Note: You may have to hold the SHIFT button on your keyboard while booting up to get this menu to show. If only one operating system is installed on your computer, it may load it automatically without displaying this menu. Remove Old Kernel Entries The most common clean up task for the boot menu is to remove old kernel versions lying around on your machine. In our case we want to remove the 2.6.32-21-generic boot menu entries. In the past, this meant opening up /boot/grub/menu.lst…but with Grub2, if we remove the kernel package from our computer, Grub automatically removes those options. To remove old kernel versions, open up Synaptic Package Manager, found in the System > Administration menu. When it opens up, type the kernel version that you want to remove in the Quick search text field. The first few numbers should suffice. For each of the entries associated with the old kernel (e.g. linux-headers-2.6.32-21 and linux-image-2.6.32-21-generic), right-click and choose Mark for Complete Removal. Click the Apply button in the toolbar and then Apply in the summary window that pops up. Close Synaptic Package Manager. The next time you boot up your computer, the Grub menu will not contain the entries associated with the removed kernel version. Remove Any Option by Editing /etc/grub.d If you need more fine-grained control, or want to remove entries that are not kernel versions, you must change the files located in /etc/grub.d. /etc/grub.d contains files that hold the menu entries that used to be contained in /boot/grub/menu.lst. If you want to add new boot menu entries, you would create a new file in this folder, making sure to mark it as executable. If you want to remove boot menu entries, as we do, you would edit files in this folder. If we wanted to remove all of the memtest86+ entries, we could just make the 20_memtest86+ file non-executable, with the terminal command sudo chmod –x 20_memtest86+ Followed by the terminal command sudo update-grub Note that memtest86+ was not found by update-grub because it will only consider executable files. However, instead, we’re going to remove the Serial console 115200 entry for memtest86+… Open a terminal window Applications > Accessories > Terminal. In the terminal window, type in the command: sudo gedit /etc/grub.d/20_memtest86+ The menu entries are found at the bottom of this file. Comment out the menu entry for serial console 115200 by adding a “#” to the start of each line. Save and close this file. In the terminal window you opened, enter in the command sudo update-grub Note: If you don’t run update-grub, the boot menu options will not change! Now, the next time you boot up, that strange entry will be gone, and you’re left with a simple and clean boot menu. Conclusion While changing Grub2’s boot menu may seem overly complicated to legacy Grub masters, for normal users, Grub2 means that you won’t have to change the boot menu that often. Fortunately, if you do have to do it, the process is still pretty easy. For more detailed information about how to change entries in Grub2, this Ubuntu forum thread is a great resource.

• .NET 3.5 Installation Problems in Windows 8

  - by Rick Strahl

  Windows 8 installs with .NET 4.5. A default installation of Windows 8 doesn't seem to include .NET 3.0 or 3.5, although .NET 2.0 does seem to be available by default (presumably because Windows has app dependencies on that). I ran into some pretty nasty compatibility issues regarding .NET 3.5 which I'll describe in this post. I'll preface this by saying that depending on how you install Windows 8 you may not run into these issues. In fact, it's probably a special case, but one that might be common with developer folks reading my blog. Specifically it's the install order that screwed things up for me -  installing Visual Studio before explicitly installing .NET 3.5 from Windows Features - in particular. If you install Visual Studio 2010 I highly recommend you install .NET 3.5 from Windows features BEFORE you install Visual Studio 2010 and save yourself the trouble I went through. So when I installed Windows 8, and then looked at the Windows Features to install after the fact in the Windows Feature dialog, I thought - .NET 3.5 - who needs it. I'd be happy to not have to install .NET 3.5, but unfortunately I found out quite a while after initial installation that one of my applications/tools (DevExpress's awesome CodeRush) depends on it and won't install without it. Enabling .NET 3.5 in Windows 8 If you want to run .NET 3.5 on Windows 8, don't download an installer - those installers don't work on Windows 8, and you don't need to do this because you can use the Windows Features dialog to enable .NET 3.5: And that *should* do the trick. If you do this before you install other apps that require .NET 3.5 and install a non-SP1 one version of it, you are going to have no problems. Unfortunately for me, even after I've installed the above, when I run the CodeRush installer I still get this lovely dialog: Now I double checked to see if .NET 3.5 is installed - it is, both for 32 bit and 64 bit. I went as far as creating a small .NET Console app and running it to verify that it actually runs. And it does… So naturally I thought the CodeRush installer is a little whacky. After some back and forth Alex Skorkin on Twitter pointed me in the right direction: He asked me to look in the registry for exact info on which version of .NET 3.5 is installed here: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP where I found that .NET 3.5 SP1 was installed. This is the 64 bit key which looks all correct. However, when I looked under the 32 bit node I found: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\NET Framework Setup\NDP\v3.5 Notice that the service pack number is set to 0, rather than 1 (which it was for the 64 bit install), which is what the installer requires. So to summarize: the 64 bit version is installed with SP1, the 32 bit version is not. Uhm, Ok… thanks for that! Easy to fix, you say - just install SP1. Nope, not so easy because the standalone installer doesn't work on Windows 8. I can't get either .NET 3.5 installer or the SP 1 installer to even launch. They simply start and hang (or exit immediately) without messages. I also tried to get Windows to update .NET 3.5 by checking for Windows Updates, which should pick up on the dated version of .NET 3.5 and pull down SP1, but that's also no go. Check for Updates doesn't bring down any updates for me yet. I'm sure at some random point in the future Windows will deem it necessary to update .NET 3.5 to SP1, but at this point it's not letting me coerce it to do it explicitly. How did this happen I'm not sure exactly whether this is the cause and effect, but I suspect the story goes like this: Installed Windows 8 without support for .NET 3.5 Installed Visual Studio 2010 which installs .NET 3.5 (no SP) I now had .NET 3.5 installed but without SP1. I then: Tried to install CodeRush - Error: .NET 3.5 SP1 required Enabled .NET 3.5 in Windows Features I figured enabling the .NET 3.5 Windows Features would do the trick. But still no go. Now I suspect Visual Studio installed the 32 bit version of .NET 3.5 on my machine and Windows Features detected the previous install and didn't reinstall it. This left the 32 bit install at least with no SP1 installed. How to Fix it My final solution was to completely uninstall .NET 3.5 *and* to reboot: Go to Windows Features Uncheck the .NET Framework 3.5 Restart Windows Go to Windows Features Check .NET Framework 3.5 and voila, I now have a proper installation of .NET 3.5. I tried this before but without the reboot step in between which did not work. Make sure you reboot between uninstalling and reinstalling .NET 3.5! More Problems The above fixed me right up, but in looking for a solution it seems that a lot of people are also having problems with .NET 3.5 installing properly from the Windows Features dialog. The problem there is that the feature wasn't properly loading from the installer disks or not downloading the proper components for updates. It turns out you can explicitly install Windows features using the DISM tool in Windows.dism.exe /online /enable-feature /featurename:NetFX3 /Source:f:\sources\sxs You can try this without the /Source flag first - which uses the hidden Windows installer files if you kept those. Otherwise insert the DVD or ISO and point at the path \sources\sxs path where the installer lives. This also gives you a little more information if something does go wrong.© Rick Strahl, West Wind Technologies, 2005-2012Posted in Windows  .NET   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• SQL SERVER – PAGELATCH_DT, PAGELATCH_EX, PAGELATCH_KP, PAGELATCH_SH, PAGELATCH_UP – Wait Type – Day 12 of 28

  - by pinaldave

  This is another common wait type. However, I still frequently see people getting confused with PAGEIOLATCH_X and PAGELATCH_X wait types. Actually, there is a big difference between the two. PAGEIOLATCH is related to IO issues, while PAGELATCH is not related to IO issues but is oftentimes linked to a buffer issue. Before we delve deeper in this interesting topic, first let us understand what Latch is. Latches are internal SQL Server locks which can be described as very lightweight and short-term synchronization objects. Latches are not primarily to protect pages being read from disk into memory. It’s a synchronization object for any in-memory access to any portion of a log or data file.[Updated based on comment of Paul Randal] The difference between locks and latches is that locks seal all the involved resources throughout the duration of the transactions (and other processes will have no access to the object), whereas latches locks the resources during the time when the data is changed. This way, a latch is able to maintain the integrity of the data between storage engine and data cache. A latch is a short-living lock that is put on resources on buffer cache and in the physical disk when data is moved in either directions. As soon as the data is moved, the latch is released. Now, let us understand the wait stat type  related to latches. From Book On-Line: PAGELATCH_DT Occurs when a task is waiting on a latch for a buffer that is not in an I/O request. The latch request is in Destroy mode. PAGELATCH_EX Occurs when a task is waiting on a latch for a buffer that is not in an I/O request. The latch request is in Exclusive mode. PAGELATCH_KP Occurs when a task is waiting on a latch for a buffer that is not in an I/O request. The latch request is in Keep mode. PAGELATCH_SH Occurs when a task is waiting on a latch for a buffer that is not in an I/O request. The latch request is in Shared mode. PAGELATCH_UP Occurs when a task is waiting on a latch for a buffer that is not in an I/O request. The latch request is in Update mode. PAGELATCH_X Explanation: When there is a contention of access of the in-memory pages, this wait type shows up. It is quite possible that some of the pages in the memory are of very high demand. For the SQL Server to access them and put a latch on the pages, it will have to wait. This wait type is usually created at the same time. Additionally, it is commonly visible when the TempDB has higher contention as well. If there are indexes that are heavily used, contention can be created as well, leading to this wait type. Reducing PAGELATCH_X wait: The following counters are useful to understand the status of the PAGELATCH: Average Latch Wait Time (ms): The wait time for latch requests that have to wait. Latch Waits/sec: This is the number of latch requests that could not be granted immediately. Total Latch Wait Time (ms): This is the total latch wait time for latch requests in the last second. If there is TempDB contention, I suggest that you read the blog post of Robert Davis right away. He has written an excellent blog post regarding how to find out TempDB contention. The same blog post explains the terms in the allocation of GAM, SGAM and PFS. If there was a TempDB contention, Paul Randal explains the optimal settings for the TempDB in his misconceptions series. Trace Flag 1118 can be useful but use it very carefully. I totally understand that this blog post is not as clear as my other blog posts. I suggest if this wait stats is on one of your higher wait type. Do leave a comment or send me an email and I will get back to you with my solution for your situation. May the looking at all other wait stats and types together become effective as this wait type can help suggest proper bottleneck in your system. Read all the post in the Wait Types and Queue series. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All the discussions of Wait Stats in this blog are generic and vary from system to system. It is recommended that you test this on a development server before implementing it to a production server.

• &ldquo;My life at Oracle&rdquo;

  - by cristian.condurache(at)oracle.com

  Hello everybody! My name is Eva and I currently work in Oracle Italy as Sales Programs Manager for the Technology Sales organization. Since 2009, I also proudly represent the Oracle Education Foundation within my country as the Ambassador for Italy. My career path in this amazing company began 5 years ago as a fresh graduate: after various years studying abroad, in Germany and Ireland mainly, I was looking for a valuable and concrete opportunity which could fulfill my energetic spirit. I wanted to develop myself inside a stimulating and “fast” business environment.. and here came Oracle and I really couldn’t ask for anything better!  THE PARTNER EXPERIENCE The first department I had the chance to work into was the Alliances and Channels organization, where I had the opportunity to join a brilliant team of great and visionary guys. I began having the responsibility to analyze and rationalize the portfolio of Oracle business partners and to identify potential cross-area solutions, which had to be highlighted both on the local market and internationally: this ended up with the implementation of the “Partner Community” model, a business environment of selected Oracle partners, specialized on the different technology focus areas. This new concept was then recognized as an EMEA Best Practice and replicated internationally. Having the opportunity to strengthen day after day strategic relationships with several business partners and study the market positioning of their technology solutions, I was given the role to develop the “Oracle Partner Network Innovation Award” in Italy: the EMEA competition encouraging and rewarding proven and successful technology innovations, creating high value for our common customers and generating new business potential. Several Italian partner solutions won different prizes and I decided that it was worth collecting all those valuable projects, winners and short-listed, inside two specific books in order also to provide them an international market visibility: OPN Innovation Award Booklet 2007 and OPN Innovation Award Booklet 2008 Inside the Alliances and Channels department I really had the opportunity to do    amazing things, like for example working side-by-side with one of the most exceptional teams in Oracle I have ever worked with: the EMEA Recruitment Team. Together, in fact, we conceived a brand new business initiative for our partners, called “Oracle Campus Joint Program”. This program was awarded as an EMEA Best Practice and acknowledged by both Italian public institutions and press media. Italy   is currently running its 5th edition.   Briefly, the “Oracle Campus Joint Program” aims at facing the growing issue of lack of  technology competences and skills on the market. By identifying a specific technology area and developing an intensive 4-6 week Oracle University training course and by collaborating with important academic institutes, international “gurus” and professionals, our business partners are able to benefit from a pool of brilliant top talented young consultants and offer them a significant career opportunity. BUSINESS BUT NOT ONLY: THE NO-PROFIT EXPERIENCE OF ORACLE Currently my mission in Oracle is to continue driving the implementation of strategic business development and sales programs for the entire Oracle Technology stack, involving both partners and the end-customers. But as a completely distinguished role from the day-today business, I’m also honored to represent in Italy the charity global organization founded by Oracle - the Oracle Education Foundation - and drive its corporate citizenship and marketing programs. Oracle Education Foundation is an independent charitable organization funded by Oracle and is dedicated to helping students develop 21st century skills through project learning and the use of technology. It provides “ThinkQuest” as a free program to primary and secondary (K12) schools. Just some significant numbers: today 548,000 students/teachers in 47 countries use ThinkQuest and the Oracle Education Foundation partners with 40+ no-profit or government organizations globally. ABOUT MYSELF AND MY INTERESTS About myself…I’m very enthusiastic and positive, trying always to transform difficult issues in challenging opportunities. My day usually begins very early in the morning with running, swimming or when I need to collect some “zen” energies with a yoga session or better with a long walk with my dog. I definitely love animals and generally speaking I’m very keen on environmental issues and try, as much as I can, to carry out a healthy and “planet respectful” lifestyle. My thirst for knowledge pushed me some time ago to begin a new personal challenge: I decided to enroll, dedicating a good part of my free time, for a second university degree: I chose “Neuroeconomics”, an innovative academic path which combines psychology, economics, and neuroscience and studies how people make decisions and the role of the brain when people evaluate these decisions, categorizing risks and rewards and generally interacting with each other. I’ve been very glad to talk about my experience in this article, as working for Oracle is something very stimulating. This company ensures you the opportunity to face new challenges, work with highly talented people and be professionally highlighted also globally. Motivation, good results and innovation is always pursued, recognized and fully supported. Thanks and wish you all an amazing career! If you have any question please contact [email protected].

• Searching for tasks with code – Executables and Event Handlers

  Searching packages or just enumerating through all tasks is not quite as straightforward as it may first appear, mainly because of the way you can nest tasks within other containers. You can see this illustrated in the sample package below where I have used several sequence containers and loops. To complicate this further all containers types, including packages and tasks, can have event handlers which can then support the full range of nested containers again. Towards the lower right, the task called SQL In FEL also has an event handler not shown, within which is another Execute SQL Task, so that makes a total of 6 Execute SQL Tasks 6 tasks spread across the package. In my previous post about such as adding a property expressionI kept it simple and just looked at tasks at the package level, but what if you wanted to find any or all tasks in a package? For this post I've written a console program that will search a package looking at all tasks no matter how deeply nested, and check to see if the name starts with "SQL". When it finds a matching task it writes out the hierarchy by name for that task, starting with the package and working down to the task itself. The output for our sample package is shown below, note it has found all 6 tasks, including the one on the OnPreExecute event of the SQL In FEL task TaskSearch v1.0.0.0 (1.0.0.0) Copyright (C) 2009 Konesans Ltd Processing File - C:\Projects\Alpha\Packages\MyPackage.dtsx MyPackage\FOR Counter Loop\SQL In Counter Loop MyPackage\SEQ For Each Loop Wrapper\FEL Simple Loop\SQL In FEL MyPackage\SEQ For Each Loop Wrapper\FEL Simple Loop\SQL In FEL\OnPreExecute\SQL On Pre Execute for FEL SQL Task MyPackage\SEQ Top Level\SEQ Nested Lvl 1\SEQ Nested Lvl 2\SQL In Nested Lvl 2 MyPackage\SEQ Top Level\SEQ Nested Lvl 1\SQL In Nested Lvl 1 #1 MyPackage\SEQ Top Level\SEQ Nested Lvl 1\SQL In Nested Lvl 1 #2 6 matching tasks found in package. The full project and code is available for download below, but first we can walk through the project to highlight the most important sections of code. This code has been abbreviated for this description, but is complete in the download. First of all we load the package, and then start by looking at the Executables for the package. // Load the package file Application application = new Application(); using (Package package = application.LoadPackage(filename, null)) { int matchCount = 0; // Look in the package's executables ProcessExecutables(package.Executables, ref matchCount); ... // // ... // Write out final count Console.WriteLine("{0} matching tasks found in package.", matchCount); } The ProcessExecutables method is a key method, as an executable could be described as the the highest level of a working functionality or container. There are several of types of executables, such as tasks, or sequence containers and loops. To know what to do next we need to work out what type of executable we are dealing with as the abbreviated version of method shows below. private static void ProcessExecutables(Executables executables, ref int matchCount) { foreach (Executable executable in executables) { TaskHost taskHost = executable as TaskHost; if (taskHost != null) { ProcessTaskHost(taskHost, ref matchCount); ProcessEventHandlers(taskHost.EventHandlers, ref matchCount); continue; } ... // // ... ForEachLoop forEachLoop = executable as ForEachLoop; if (forEachLoop != null) { ProcessExecutables(forEachLoop.Executables, ref matchCount); ProcessEventHandlers(forEachLoop.EventHandlers, ref matchCount); continue; } } } As you can see if the executable we find is a task we then call out to our ProcessTaskHost method. As with all of our executables a task can have event handlers which themselves contain more executables such as task and loops, so we also make a call out our ProcessEventHandlers method. The other types of executables such as loops can also have event handlers as well as executables. As shown with the example for the ForEachLoop we call the same ProcessExecutables and ProcessEventHandlers methods again to drill down into the hierarchy of objects that the package may contain. This code needs to explicitly check for each type of executable (TaskHost, Sequence, ForLoop and ForEachLoop) because whilst they all have an Executables property this is not from a common base class or interface. This example was just a simple find a task by its name, so ProcessTaskHost really just does that. We also get the hierarchy of objects so we can write out for information, obviously you can adapt this method to do something more interesting such as adding a property expression. private static void ProcessTaskHost(TaskHost taskHost, ref int matchCount) { if (taskHost == null) { return; } // Check if the task matches our match name if (taskHost.Name.StartsWith(TaskNameFilter, StringComparison.OrdinalIgnoreCase)) { // Build up the full object hierarchy of the task // so we can write it out for information StringBuilder path = new StringBuilder(); DtsContainer container = taskHost; while (container != null) { path.Insert(0, container.Name); container = container.Parent; if (container != null) { path.Insert(0, "\\"); } } // Write the task path // e.g. Package\Container\Event\Task Console.WriteLine(path); Console.WriteLine(); // Increment match counter for info matchCount++; } } Just for completeness, the other processing method we covered above is for event handlers, but really that just calls back to the executables. This same method is called in our main package method, but it was omitted for brevity here. private static void ProcessEventHandlers(DtsEventHandlers eventHandlers, ref int matchCount) { foreach (DtsEventHandler eventHandler in eventHandlers) { ProcessExecutables(eventHandler.Executables, ref matchCount); } } As hopefully the code demonstrates, executables (Microsoft.SqlServer.Dts.Runtime.Executable) are the workers, but within them you can nest more executables (except for task tasks).Executables themselves can have event handlers which can in turn hold more executables. I have tried to illustrate this highlight the relationships in the following diagram. Download Sample code project TaskSearch.zip (11KB)

• Troubleshooting High-CPU Utilization for SQL Server

  - by Susantha Bathige

  The objective of this FAQ is to outline the basic steps in troubleshooting high CPU utilization on  a server hosting a SQL Server instance. The first and the most common step if you suspect high CPU utilization (or are alerted for it) is to login to the physical server and check the Windows Task Manager. The Performance tab will show the high utilization as shown below: Next, we need to determine which process is responsible for the high CPU consumption. The Processes tab of the Task Manager will show this information: Note that to see all processes you should select Show processes from all user. In this case, SQL Server (sqlserver.exe) is consuming 99% of the CPU (a normal benchmark for max CPU utilization is about 50-60%). Next we examine the scheduler data. Scheduler is a component of SQLOS which evenly distributes load amongst CPUs. The query below returns the important columns for CPU troubleshooting. Note – if your server is under severe stress and you are unable to login to SSMS, you can use another machine’s SSMS to login to the server through DAC – Dedicated Administrator Connection (see http://msdn.microsoft.com/en-us/library/ms189595.aspx for details on using DAC) SELECT scheduler_id ,cpu_id ,status ,runnable_tasks_count ,active_workers_count ,load_factor ,yield_count FROM sys.dm_os_schedulers WHERE scheduler_id See below for the BOL definitions for the above columns. scheduler_id – ID of the scheduler. All schedulers that are used to run regular queries have ID numbers less than 1048576. Those schedulers that have IDs greater than or equal to 1048576 are used internally by SQL Server, such as the dedicated administrator connection scheduler. cpu_id – ID of the CPU with which this scheduler is associated. status – Indicates the status of the scheduler. runnable_tasks_count – Number of workers, with tasks assigned to them that are waiting to be scheduled on the runnable queue. active_workers_count – Number of workers that are active. An active worker is never preemptive, must have an associated task, and is either running, runnable, or suspended. current_tasks_count - Number of current tasks that are associated with this scheduler. load_factor – Internal value that indicates the perceived load on this scheduler. yield_count – Internal value that is used to indicate progress on this scheduler.                                                                 Now to interpret the above data. There are four schedulers and each assigned to a different CPU. All the CPUs are ready to accept user queries as they all are ONLINE. There are 294 active tasks in the output as per the current_tasks_count column. This count indicates how many activities currently associated with the schedulers. When a  task is complete, this number is decremented. The 294 is quite a high figure and indicates all four schedulers are extremely busy. When a task is enqueued, the load_factor  value is incremented. This value is used to determine whether a new task should be put on this scheduler or another scheduler. The new task will be allocated to less loaded scheduler by SQLOS. The very high value of this column indicates all the schedulers have a high load. There are 268 runnable tasks which mean all these tasks are assigned a worker and waiting to be scheduled on the runnable queue.   The next step is  to identify which queries are demanding a lot of CPU time. The below query is useful for this purpose (note, in its current form,  it only shows the top 10 records). SELECT TOP 10 st.text  ,st.dbid  ,st.objectid  ,qs.total_worker_time  ,qs.last_worker_time  ,qp.query_plan FROM sys.dm_exec_query_stats qs CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) st CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) qp ORDER BY qs.total_worker_time DESC This query as total_worker_time as the measure of CPU load and is in descending order of the  total_worker_time to show the most expensive queries and their plans at the top:      Note the BOL definitions for the important columns: total_worker_time - Total amount of CPU time, in microseconds, that was consumed by executions of this plan since it was compiled. last_worker_time - CPU time, in microseconds, that was consumed the last time the plan was executed.   I re-ran the same query again after few seconds and was returned the below output. After few seconds the SP dbo.TestProc1 is shown in fourth place and once again the last_worker_time is the highest. This means the procedure TestProc1 consumes a CPU time continuously each time it executes.      In this case, the primary cause for high CPU utilization was a stored procedure. You can view the execution plan by clicking on query_plan column to investigate why this is causing a high CPU load. I have used SQL Server 2008 (SP1) to test all the queries used in this article.

• SQL SERVER – Guest Post by Sandip Pani – SQL Server Statistics Name and Index Creation

  - by pinaldave

  Sometimes something very small or a common error which we observe in daily life teaches us new things. SQL Server Expert Sandip Pani (winner of Joes 2 Pros Contests) has come across similar experience. Sandip has written a guest post on an error he faced in his daily work. Sandip is working for QSI Healthcare as an Associate Technical Specialist and have more than 5 years of total experience. He blogs at SQLcommitted.com and contribute in various forums. His social media hands are LinkedIn, Facebook and Twitter. Once I faced following error when I was working on performance tuning project and attempt to create an Index. Mug 1913, Level 16, State 1, Line 1 The operation failed because an index or statistics with name ‘Ix_Table1_1′ already exists on table ‘Table1′. The immediate reaction to the error was that I might have created that index earlier and when I researched it further I found the same as the index was indeed created two times. This totally makes sense. This can happen due to many reasons for example if the user is careless and executes the same code two times as well, when he attempts to create index without checking if there was index already on the object. However when I paid attention to the details of the error, I realize that error message also talks about statistics along with the index. I got curious if the same would happen if I attempt to create indexes with the same name as statistics already created. There are a few other questions also prompted in my mind. I decided to do a small demonstration of the subject and build following demonstration script. The goal of my experiment is to find out the relation between statistics and the index. Statistics is one of the important input parameter for the optimizer during query optimization process. If the query is nontrivial then only optimizer uses statistics to perform a cost based optimization to select a plan. For accuracy and further learning I suggest to read MSDN. Now let’s find out the relationship between index and statistics. We will do the experiment in two parts. i) Creating Index ii) Creating Statistics We will be using the following T-SQL script for our example. IF (OBJECT_ID('Table1') IS NOT NULL) DROP TABLE Table1 GO CREATE TABLE Table1 (Col1 INT NOT NULL, Col2 VARCHAR(20) NOT NULL) GO We will be using following two queries to check if there are any index or statistics on our sample table Table1. -- Details of Index SELECT OBJECT_NAME(OBJECT_ID) AS TableName, Name AS IndexName, type_desc FROM sys.indexes WHERE OBJECT_NAME(OBJECT_ID) = 'table1' GO -- Details of Statistics SELECT OBJECT_NAME(OBJECT_ID) TableName, Name AS StatisticsName FROM sys.stats WHERE OBJECT_NAME(OBJECT_ID) = 'table1' GO When I ran above two scripts on the table right after it was created it did not give us any result which was expected. Now let us begin our test. 1) Create an index on the table Create following index on the table. CREATE NONCLUSTERED INDEX Ix_Table1_1 ON Table1(Col1) GO Now let us use above two scripts and see their results. We can see that when we created index at the same time it created statistics also with the same name. Before continuing to next set of demo – drop the table using following script and re-create the table using a script provided at the beginning of the table. DROP TABLE table1 GO 2) Create a statistic on the table Create following statistics on the table. CREATE STATISTICS Ix_table1_1 ON Table1 (Col1) GO Now let us use above two scripts and see their results. We can see that when we created statistics Index is not created. The behavior of this experiment is different from the earlier experiment. Clean up the table setup using the following script: DROP TABLE table1 GO Above two experiments teach us very valuable lesson that when we create indexes, SQL Server generates the index and statistics (with the same name as the index name) together. Now due to the reason if we have already had statistics with the same name but not the index, it is quite possible that we will face the error to create the index even though there is no index with the same name. A Quick Check To validate that if we create statistics first and then index after that with the same name, it will throw an error let us run following script in SSMS. Make sure to drop the table and clean up our sample table at the end of the experiment. -- Create sample table CREATE TABLE TestTable (Col1 INT NOT NULL, Col2 VARCHAR(20) NOT NULL) GO -- Create Statistics CREATE STATISTICS IX_TestTable_1 ON TestTable (Col1) GO -- Create Index CREATE NONCLUSTERED INDEX IX_TestTable_1 ON TestTable(Col1) GO -- Check error /*Msg 1913, Level 16, State 1, Line 2 The operation failed because an index or statistics with name 'IX_TestTable_1' already exists on table 'TestTable'. */ -- Clean up DROP TABLE TestTable GO While creating index it will throw the following error as statistics with the same name is already created. In simple words – when we create index the name of the index should be different from any of the existing indexes and statistics.

• Some New .NET Toys (Repost)

  - by Kevin Grossnicklaus

  Last week I was fortunate enough to spend time in Redmond on Microsoft’s campus for the 2011 Microsoft MVP Summit. It was great to hang out with a number of old friends and get the opportunity to talk tech with the various product teams up at Microsoft. The weather wasn’t exactly sunny but Microsoft always does a great job with the Summit and everyone had a blast (heck, I even got to run the bases at SafeCo field) While much of what we saw is covered under NDA, there a ton of great things in the pipeline from Microsoft and many things that are already available (or just became so) that I wasn’t necessarily aware of. The purpose of this post is to share some of the info I learned on resources and tools available to .NET developers today. Please let me know if you have any questions (or if you know of something else cool which might benefit others). Enjoy! Visual Studio 2010 SP1 Microsoft has issued the RTM release of Visual Studio 2010 SP1. You can download the full SP1 on MSDN as of today (March 10th to the general public) and take advantage of such things as: Silverlight 4 is included in the box (as opposed to a separate install) Silverlight 4 Profiling WCF RIA Services SP1 Intellitrace for 64-bit and SharePoint ASP.NET now easily supports IIS Express and SQL CE Want a description of all that’s new beyond the above biased list (which arguably only contains items I think are important)? Check out this KB article. Portable Library Tools CTP Without much fanfare Microsoft has released a CTP of a new add-in to Visual Studio 2010 which simplifies code sharing between projects targeting different runtimes (i.e. Silverlight, WPF, Win7 Phone, XBox). With this Add-In installed you can add a new project of type “Portable Library” and specify which platforms you wish to target. Once that is done, any code added to this library will be limited to use only features which are common to all selected frameworks. Other projects can now reference this portable library and be provided assemblies custom built to their environment. This greatly simplifies the current process of sharing linked files between platforms like WPF and Silverlight. You can find out more about this CTP and how it works on this great blog post. Visual Studio Async CTP Microsoft has also released a CTP of a set of language and framework enhancements to provide a much more powerful asynchronous programming model. Due to the focus on async programming in all types of platforms (and it being the ONLY option in Silverlight and Win7 phone) a move towards a simpler and more understandable model is always a good thing. This CTP (called Visual Studio Async CTP) can be downloaded here. You can read more about this CTP on this blog post. MSDN Code Samples Gallery Microsoft has also launched new code samples gallery on their MSDN site: http://code.msdn.microsoft.com/. This site allows you to easily search for small samples of code related to a particular technology or platform. If a sample of code you are looking for is not found, you can request one via the site and other developers can see your request and provide a sample to the site to suit your needs. You can also peruse requested samples and, if you find a scenario where you can provide value, upload your own sample for the benefit of others. Samples are packaged into the VS .vsix format and include any necessary references/dependencies. By using .vsix as the deployment mechanism, as samples are installed from the site they are kept in your Visual Studio 2010 Samples Gallery and kept for your future reference. If you get a chance, check out the site and see how it is done. Although a somewhat simple concept, I was very impressed with their implementation and the way they went about trying to suit a need. I’ll definitely be looking there in the future as need something or want to share something. MSDN Search Capabilities Another item I learned recently and was not aware of (that might seem trivial to some) is the power of the MSDN site’s search capabilities. Between the Code Samples Gallery described above and the search enhancements on MSDN, Microsoft is definitely investing in their platform to help provide developers of all skill levels the tools and resources they need to be successful. What do I mean by the MSDN search capability and why should you care? If you go to the MSDN home page (http://msdn.microsoft.com) and use the “Search MSDN with Big” box at the very top of the page you will see some very interesting results. First, the search actually doesn’t just search the MSDN library it searches: MSDN Library All Microsoft Blogs CodePlex StackOverflow Downloads MSDN Magazine Support Knowledgebase (I’m not sure it even ends there but the above are all I know of) Beyond just searching all the above locations, the results are formatted very nicely to give some contextual information based on where the result came from. For example, if a keyword search returned results from CodePlex, each row in the search results screen would include a large amount of information specific to CodePlex such as: Looking at the above results immediately tells you everything from the page views to the CodePlex ratings. All in all, knowing that this much information is indexed and available from a single search location will lead me to utilize this as one of my initial searches for development information.

• Social Business Forum Milano: Day 2

  - by me

  @YourService. The business world has flipped and small business can capitalize  by Frank Eliason (twitter: @FrankEliason ) Technology and social media tools have made it easier than ever for companies to communicate with consumers. They can listen and join in on conversations, solve problems, get instant feedback about their products and services, and more. So why, then, are most companies not doing this? Instead, it seems as if customer service is at an all time low, and that the few companies who are choosing to focus on their customers are experiencing a great competitive advantage. At Your Service explains the importance of refocusing your business on your customers and your employees, and just how to do it. Explains how to create a culture of empowered employees who understand the value of a great customer experience Advises on the need to communicate that experience to their customers and potential customers Frank Eliason, recognized by BusinessWeek as the 'most famous customer service manager in the US, possibly in the world,' has built a reputation for helping large businesses improve the way they connect with customers and enhance their relationships Quotes from the Audience: Bertrand Duperrin ?@bduperrin social service is not about shutting up the loudest cutsomers ! #sbf12 @frankeliason Paolo Pelloni ?@paolopelloniGautam Ghosh ?@GautamGhosh RT @cecildijoux: #sbf12 @frankeliason you need to change things and fix the approach it's not about social media it's about driving change  Peter H.

John shared some great best practices on how to deploy an enterprise wide  community model  in a large company. He started with the most important question What is the commercial value of adding social ? Then he talked about the success of Community of Practices deployment and outlined some key use cases including the relevant measures to proof the ROI of the investment. Examples:  Community of practice -> measure: systematic collection of value stories  Self-service website  -> measure: based on representative models Optimizing asset inventory - > measure: Actual counts  This use case was particular interesting.  It is a crowd sourced spending/saving of infrastructure model.  User can cancel IT services they don't need (as example Software xx).  5% of the saving goes to social responsibility projects. The John outlined some  best practices on how to address the WIIFM (What's In It For Me) question of the individual users:  - change from hierarchy to graph -  working out loud = observable work + narrating  your work  - add social skills to career objectives - example: building a purposeful social network course/training as part of the job development curriculum And last but not least John gave some important tips on how to get senior management buy-in by establishing management sponsored division level collaboration boards which defines clear uses cases and measures.

• Parallelism in .NET – Part 17, Think Continuations, not Callbacks

  - by Reed

  In traditional asynchronous programming, we’d often use a callback to handle notification of a background task’s completion.  The Task class in the Task Parallel Library introduces a cleaner alternative to the traditional callback: continuation tasks. Asynchronous programming methods typically required callback functions.  For example, MSDN’s Asynchronous Delegates Programming Sample shows a class that factorizes a number.  The original method in the example has the following signature: public static bool Factorize(int number, ref int primefactor1, ref int primefactor2) { //... .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } However, calling this is quite “tricky”, even if we modernize the sample to use lambda expressions via C# 3.0.  Normally, we could call this method like so: int primeFactor1 = 0; int primeFactor2 = 0; bool answer = Factorize(10298312, ref primeFactor1, ref primeFactor2); Console.WriteLine("{0}/{1} [Succeeded {2}]", primeFactor1, primeFactor2, answer); If we want to make this operation run in the background, and report to the console via a callback, things get tricker.  First, we need a delegate definition: public delegate bool AsyncFactorCaller( int number, ref int primefactor1, ref int primefactor2); Then we need to use BeginInvoke to run this method asynchronously: int primeFactor1 = 0; int primeFactor2 = 0; AsyncFactorCaller caller = new AsyncFactorCaller(Factorize); caller.BeginInvoke(10298312, ref primeFactor1, ref primeFactor2, result => { int factor1 = 0; int factor2 = 0; bool answer = caller.EndInvoke(ref factor1, ref factor2, result); Console.WriteLine("{0}/{1} [Succeeded {2}]", factor1, factor2, answer); }, null); This works, but is quite difficult to understand from a conceptual standpoint.  To combat this, the framework added the Event-based Asynchronous Pattern, but it isn’t much easier to understand or author. Using .NET 4’s new Task<T> class and a continuation, we can dramatically simplify the implementation of the above code, as well as make it much more understandable.  We do this via the Task.ContinueWith method.  This method will schedule a new Task upon completion of the original task, and provide the original Task (including its Result if it’s a Task<T>) as an argument.  Using Task, we can eliminate the delegate, and rewrite this code like so: var background = Task.Factory.StartNew( () => { int primeFactor1 = 0; int primeFactor2 = 0; bool result = Factorize(10298312, ref primeFactor1, ref primeFactor2); return new { Result = result, Factor1 = primeFactor1, Factor2 = primeFactor2 }; }); background.ContinueWith(task => Console.WriteLine("{0}/{1} [Succeeded {2}]", task.Result.Factor1, task.Result.Factor2, task.Result.Result)); This is much simpler to understand, in my opinion.  Here, we’re explicitly asking to start a new task, then continue the task with a resulting task.  In our case, our method used ref parameters (this was from the MSDN Sample), so there is a little bit of extra boiler plate involved, but the code is at least easy to understand. That being said, this isn’t dramatically shorter when compared with our C# 3 port of the MSDN code above.  However, if we were to extend our requirements a bit, we can start to see more advantages to the Task based approach.  For example, supposed we need to report the results in a user interface control instead of reporting it to the Console.  This would be a common operation, but now, we have to think about marshaling our calls back to the user interface.  This is probably going to require calling Control.Invoke or Dispatcher.Invoke within our callback, forcing us to specify a delegate within the delegate.  The maintainability and ease of understanding drops.  However, just as a standard Task can be created with a TaskScheduler that uses the UI synchronization context, so too can we continue a task with a specific context.  There are Task.ContinueWith method overloads which allow you to provide a TaskScheduler.  This means you can schedule the continuation to run on the UI thread, by simply doing: Task.Factory.StartNew( () => { int primeFactor1 = 0; int primeFactor2 = 0; bool result = Factorize(10298312, ref primeFactor1, ref primeFactor2); return new { Result = result, Factor1 = primeFactor1, Factor2 = primeFactor2 }; }).ContinueWith(task => textBox1.Text = string.Format("{0}/{1} [Succeeded {2}]", task.Result.Factor1, task.Result.Factor2, task.Result.Result), TaskScheduler.FromCurrentSynchronizationContext()); This is far more understandable than the alternative.  By using Task.ContinueWith in conjunction with TaskScheduler.FromCurrentSynchronizationContext(), we get a simple way to push any work onto a background thread, and update the user interface on the proper UI thread.  This technique works with Windows Presentation Foundation as well as Windows Forms, with no change in methodology.

• Sun Fire X4800 M2 Delivers World Record TPC-C for x86 Systems

  - by Brian

  Oracle's Sun Fire X4800 M2 server equipped with eight 2.4 GHz Intel Xeon Processor E7-8870 chips obtained a result of 5,055,888 tpmC on the TPC-C benchmark. This result is a world record for x86 servers. Oracle demonstrated this world record database performance running Oracle Database 11g Release 2 Enterprise Edition with Partitioning. The Sun Fire X4800 M2 server delivered a new x86 TPC-C world record of 5,055,888 tpmC with a price performance of $0.89/tpmC using Oracle Database 11g Release 2. This configuration is available 06/26/12. The Sun Fire X4800 M2 server delivers 3.0x times better performance than the next 8-processor result, an IBM System p 570 equipped with POWER6 processors. The Sun Fire X4800 M2 server has 3.1x times better price/performance than the 8-processor 4.7GHz POWER6 IBM System p 570. The Sun Fire X4800 M2 server has 1.6x times better performance than the 4-processor IBM x3850 X5 system equipped with Intel Xeon processors. This is the first TPC-C result on any system using eight Intel Xeon Processor E7-8800 Series chips. The Sun Fire X4800 M2 server is the first x86 system to get over 5 million tpmC.

It simulates a complete environment where a population of terminal operators executes transactions against a database. The benchmark is centered around the principal activities (transactions) of an order-entry environment. These transactions include entering and delivering orders, recording payments, checking the status of orders, and monitoring the level of stock at the warehouses. Key Points and Best Practices Oracle Database 11g Release 2 Enterprise Edition with Partitioning scales easily to this high level of performance. COMSTAR (Common Multiprotocol SCSI Target) is the software framework that enables an Oracle Solaris host to serve as a SCSI Target platform. COMSTAR uses a modular approach to break the huge task of handling all the different pieces in a SCSI target subsystem into independent functional modules which are glued together by the SCSI Target Mode Framework (STMF). The modules implementing functionality at SCSI level (disk, tape, medium changer etc.) are not required to know about the underlying transport. And the modules implementing the transport protocol (FC, iSCSI, etc.) are not aware of the SCSI-level functionality of the packets they are transporting. The framework hides the details of allocation providing execution context and cleanup of SCSI commands and associated resources and simplifies the task of writing the SCSI or transport modules. Oracle iPlanet Web Server middleware is used for the client tier of the benchmark. Each web server instance supports more than a quarter-million users while satisfying the response time requirement from the TPC-C benchmark.
