  • Setup basic proxypass in Apache

    - by Eric
    I have a web application that communicates to a web service deployed on the same server. The web app was written with Tibco General Interface and works well only when it is running locally on the development system. When I deploy the web app to the Apache server it fails with code 200 apparently due to cross domain data. I use Firefox as a browser. I have tried changing Internet Explorer to access cross domain data and it works however IE is not an option. Web application runs on 192.168.2.205 (port 80). Web service runs on 192.168.2.205:8040 I have tried a number of things with proxypass inside Apache with no luck.

  • Why use flash to as content headings? Why not?

    - by Itai
    A large number of sites lately which use Flash to replace what would be simple HTML headings (h1, h2, h3). Some of them do it consistently for every header. Why would you do this? What are the pros and cons of this? This seems strange to me and really inefficient, particularly since a page can have dozens of headers. I notice this because I use Flash Block (which temporarily disables Flash), so not everyone may have seen it. Just today I landed here with 4 flash headers. I've seen dozens of such use of Flash this week alone, and I am wondering if this has some benefits.

  • How to program for constraints/rules

    - by Gaurav
    First the background, during interviews in the past, many times I have been asked to design some or other variation of card game as programming puzzle, and I have tried to design it in OO way, but I have never been satisfied with my solutions. However it was not until recently that I realized that I had been approaching the problem from the wrong direction. Specifically I was trying to solve the problem by modeling individual card as an object. Problem with this is individual cards don't have any non-trivial intrinsic behavior and therefore are not suitable (or primary) candidate as objects. What is interesting and important about cards are rules and constraints, such as there could be only four suits, or only thirteen cards in each suit. Of course, then there are any number of rules for games. So my questions are Are there any idioms/constructs/patterns to program for rules & constraints. How many in 1 can be applied in conjunction with OO paradigm.

  • What units does the ntp drift file use?

    - by arielf
    When the ntpd daemon is running, the file: /var/lib/ntp/ntp.drift gets updated periodically. Example: 17:20 hostname 118 ~> ls -l /var/lib/ntp/ntp.drift -rw-r--r-- 1 ntp ntp 7 May 20 16:46 /var/lib/ntp/ntp.drift # So it looks like it was last updated ~34 minutes ago The file has one number in it, for example, looking at a 4 virtual hosts, I find these values, respectively: -22.086 -10.214 -13.669 6.045 I assume these are seconds per day(?), but not sure. man ntpd mentions a different drift file /etc/ntp.drift which doesn't seem to exist. The man page doesn't explain what units are being used for the drift. Questions: Is /etc/ntp.drift actually /var/lib/ntp/ntp.drift on Ubuntu? What units is the drift expressed in? Thanks!

  • Google adwords API - credit card safety question

    - by anon
    Hi, Google is asking me to fax credit card xerox in order to activate adwords API in MCC. This really sucks imo... they could have had prepaid option. In any case, my questions: 1) Are there alternatives to this - is there a 3rd party provider who will give me this service without me sending them the credit card info? 2) How secure is it to send my credit card fax via some online fax service? 3) Do you think they will reject the application if I hide my CVV number in the fax? Any other thoughts appreciated :) thanks

  • Transitioning to asynchronous programming model

    - by Simone
    our team is mantaining and developing a .NET web service written in C#. We have stress tested the web service's farm and we have evidence that the actual architecture doesn't scale well, as the number of request are constantly increasing. We analyzed Martin Fowler's conclusion in this article, and our team feels that migrating to an asynchronous programming model such as the one described could be the right direction to point to for our service too. My question is: do you think that this "switch" needs a complete rewrite of the application? Has been someone of you been able to adopt APM without rewriting everything and has some insight to share? Thank you in advance

  • How can architects work with self-organizing Scrum teams?

    - by Martin Wickman
    An organization with a number of agile Scrum teams also has a small group of people appointed as "enterprise architects". The EA group acts as control and gatekeeper for quality and adherence to decisions. This leads to overlaps between the team decision and EA decisions. For instance, the team might want to use library X or want to use REST instead of SOAP, but the EA does not approve of that. Now, this can lead to frustration when team decisions are overruled. Taken far enough, it can potentially lead to a situation where the EA people "grabs" all power and the team ends up feeling demotivated and not very agile at all. The Scrum guides has this to say about it: Self-organizing: No one (not even the Scrum Master) tells the Development Team how to turn Product Backlog into Increments of potentially releasable functionality. Is that reasonable? Should the EA team be disbanded? Should the teams refuse or simply comply?

  • How to Automatically Backup Your Gmail Attachments With IFTTT

    - by Mark Wilson
    When it comes to getting things done quickly, automation is the name of the game. We’ve looked at IFTTT before, and a new batch of updates has introduced a number of options that can be used to automatically do things with files that are sent to your Gmail address. What could this be used for? Well the most obvious starting point is to simply create a backup of any files that you receive via email. This is useful if you find that you often reach the size limit for your inbox as it enables you to delete emails without having to worry about losing the associated files. Start by paying a visit to the IFTTT website and then either sign into an existing account or create a new one.

  • How could RDBMSes be considered a fad?

    - by StuperUser
    Completing my Computing A-level in 2003 and getting a degree in Computing in 2007, and learning my trade in a company with a lot of SQL usage, I was brought up on the idea of Relational Databases being used for storage. So, despite being relatively new to development, I was taken-aback to read a comment (on Is LinqPad site quote "Tired of querying in antiquated SQL?" accurate? ) that said: [Some devs] despise [SQL] and think that it and RDBMS are a fad Obviously, a competent dev will use the right tool for the right job and won't create a relational database when e.g. flat file or another solution for storage is appropriate, but RDBMs are useful in a massive number of circumstances, so how could they be considered a fad?

  • Compiler Dependencies [closed]

    - by asghar ashgari
    I'm a newbie researcher who's passion is programming languages (Web era). I'm wondering why all the Web frameworks and Web-based general purposes languages, have a huge number of dependencies when you want to install and then use (e.g., extend, alternate, etc.) their compilers. For example, Ruby on Rails or Scala. If I want to download their source code, and try to build it again, to me at least, feels like a can of worms. I have a MAC, so I need to install MACports, then update my XCode, then get the compiler source code that has bunch of other dependencies, then its hard to set things up; just to see the installed open-source compiler works fine.

  • Silverlight Cream for January 11, 2011 -- #1024

    - by Dave Campbell
    1,000 blogposts is quite a few, but to die-hard geeks, 1000 isn't the number... 1K is the number, and today is my 1K blogpost! I've been working up to this for at least 11 months. Way back at MIX10, I approached some vendors about an idea I had. A month ago I contacted them and others, and everyone I contacted was very generous and supportive of my idea. My idea was not to run a contest, but blog as normal, and whoever ended up on my 1K post would get some swag... and I set a cut-off at 13 posts. So... blogging normally, I had some submittals, and then ran my normal process to pick up the next posts until I hit a total of 13. To provide a distribution channel for the swag, everyone on the list, please send me your snail mail (T-shirts) and email (licenses) addresses as soon as possible.   I'd like to thank the following generous sponsors for their contributions to my fun (in alphabetic order): and Rachel Hawley for contributing 4 Silverlight control sets First Floor Software and Koen Zwikstra for contributing 13 licenses for Silverlight Spy and Sara Faatz/Jason Beres for contributing 13 licenses for Silverlight Data Visualization controls and Svetla Stoycheva for contributing T-Shirts for everyone on the post and Ina Tontcheva for contributing 13 licenses for RadControls for Silverlight + RadControls for Windows Phone and Charlene Kozlan for contributing 1 combopack standard, 2 DataGrid for Silverlight, and 2 Listbox for Silverlight Standard And now finally...in this Issue: Nigel Sampson, Jeremy Likness, Dan Wahlin, Kunal Chowdhurry, Alex Knight, Wei-Meng Lee, Michael Crump, Jesse Liberty, Peter Kuhn, Michael Washington, Tau Sick, Max Paulousky, Damian Schenkelman Above the Fold: Silverlight: "Demystifying Silverlight Dependency Properties" Dan Wahlin WP7: "Using Windows Phone Gestures as Triggers" Nigel Sampson Expression Blend: "PathListBox: making data look cool" Alex Knight From SilverlightCream.com: Using Windows Phone Gestures as Triggers Nigel Sampson blogged about WP7 Gestures, the Toolkit, and using Gestures as Triggers, and actually makes it looks simple :) Jounce Part 9: Static and Dynamic Module Management Jeremy Likness has episode 9 of his explanation of his MVVM framework, Jounce, up... and a big discussion of Modules and Module Management from a Jounce perspective. Demystifying Silverlight Dependency Properties Dan Wahlin takes a page from one of his teaching opportunities, and shares his knowledge of Dependency Properties with us... beginning with what they are, defining them in code, and demonstrating their use. Customizing Silverlight ChildWindow Style using Blend Kunal Chowdhurry has a great post up about getting your Child Windows to match the look & feel of the rest of youra app... plus a bunch of Blend goodness thrown in. PathListBox: making data look cool File this post by Alex Knight in the 'holy crap' file along with the others in this series! ... just check out that cool Ticker Style Path ListBox at the top of the blog... too cool! Web Access in Windows Phone 7 Apps Wei-Meng Lee has the 3rd part of his series on WP7 development up and in this one is discussing Web Access... I mean *discussing* it... tons of detail, code, and explanation... great post. Prevent your Silverlight XAP file from caching in your browser. Michael Crump helps relieve stress on Silverlight developers everywhere by exploring how to avoid caching of your XAP in the browser... (WPFS) MVVM Light Toolkit: Soup To Nuts Part I Jesse Liberty continues his Windows Phone from Scratch series with a new segment exploring Laurent Bugnion's MVVMLight Toolkit beginning with acquiring and installing the toolkit, then proceeds to discuss linking the View and ViewModel, the ViewModel Locator, and page navigation.

Windows Phone 7 Animated Button Press Michael Washington took exception to button presses that gave no visual feedback and produced a behavior that does just that. Using TweetSharp in a Windows Phone 7 app Tau Sick demonstrates using TweetSharp to put a twitter feed into a WP7 app, as he did in "Hangover Helper"... all the instructions from getting Tweeetshaprt to the code necessary. Bindable Application Bar Extensions for Windows Phone 7 Max Paulousky has a post discussing some real extensions to the ApplicationBar for WP7.. he begins with a bindable application bar by Nicolas Humann that I've missed, probably because his blog is in French... and extends it to allow using DelegateCommand. How to: Load Prism modules packaged in a separate XAP file in an OOB application Damian Schenkelman posts about Prism, AppModules in separate XAPs and running OOB... if you've tried this, you know it's a hassle..

  • Web Application Tasks Estimation

    - by Ali
    I know the answer depends on the exact project and its requirements but i am asking on the avarage % of the total time goes into the tasks of the web application development statistically from your own experiance. While developing a web application (database driven) How much % of time does each of the following activities usually takes: -- database creation & all related stored procedures -- server side development -- client side development -- layout settings and designing I know there are lots of great web application developers around here and each one of you have done fair amount of web development and as a result there could be an almost fixed percentage of time going to each of the above activities of web developments for standard projects Update : I am not expecting someone to tell me number of hours i am asking about the average percentage of time that goes on each of the activities as per your experience i.e. server side dev 50%, client side development 20% ,,,,, I repeat there will be lots of cases that differs from the standard depending on the exact requirments of each web application project but here i am asking about Avarage for standard (no special requirment) web project

  • Web Site Performance and Assembly Versioning – Part 2 Versioning Combined Files Using Subversion

    - by capgpilk
    Ok so it took a while to post this second part. Many apologies, we had a big roll out of a new platform at work and many things had to get sidelined. So this is the second part in a short series of website performance and using versioning to help improve it. Minification and Concatination of JavaScript and CSS Files Versioning Combined Files Using Subversion – this post Versioning Combined Files Using Mercurial – published shortly In the previous post we used AjaxMin to shrink js and css files then concatenated them into one file each which had the file name of site-script.combined.min.js and site-style.combined.min.css. These file names are fine, but you can configure IIS 7 to cache these static files and so lower the amount of data transferred between server and client. This is done by editing the response headers in IIS. 1. In IIS7 Manager, choose the directory where these files are located and select HTTP Response Headers. 2. Check the Expire Web Content and set a time period well into the future. 3. When refreshing the web page, the server will respond with HTTP 304 forcing the browser to retrieve the file from its cache. 4. As can be seen in FireBug, the Cache-Control header has a max age of 31536000 seconds which equates to 365 days.   The server will always send this HTTP 304 message unless the file changes forcing it to send new content. To help force this we can change the file name based on the latest build using the SVN revision number in the filename. So we have lowered data transfer on content that hasn’t changed, but forced it to be sent when you have made a change to the css or js files. Now to get the SVN revision number in to the file name. 1. Import the MSBuildCommunityTasks targets which can be dowloaded from here. 1: <Import Project="$(MSBuildExtensionsPath) 2: \MSBuildCommunityTasks 3: \MSBuild.Community.Tasks.Targets" /> 2. Edit the BeforeBuild target to call out to svn and get the latest revision 1: <SvnVersion LocalPath="$(MSBuildProjectDirectory)" 2: ToolPath="$(ProgramFiles)\VisualSVN Server\bin"> 3: <Output TaskParameter="Revision" PropertyName="Revision" /> 4: </SvnVersion> 3. Set it to update the project AssemblyInfo.cs file for the svn revision. 1: <FileUpdate Files="Properties\AssemblyInfo.cs" 2: Regex="(\d+)\.(\d+)\.(\d+)\.(\d+)" 3: ReplacementText="$1.$2.$3.$(Revision)" /> 4. Now edit the AfterBuild target to get the full dll version. You could combine these two steps and just get the version from svn, I am working on one project that updates the AssemblyInfo file and another project that allows manual editing of the file, but needs that version within the file name; so I just combined the two for this post. 1: <MSBuild.ExtensionPack.Framework.Assembly 2: TaskAction="GetInfo" 3: NetAssembly="$(OutputPath)\mydll.dll"> 4: <Output TaskParameter="OutputItems" ItemName="Info" /> 5: </MSBuild.ExtensionPack.Framework.Assembly> 6: <Message Text="Version: %(Info.AssemblyVersion)" 7: Importance="High" /> 5. Use this Info.AssemblyVersion to write out the combined css and js files as described in the last post. 1: <WriteLinestoFile File="Scripts\site-%(Info.AssemblyVersion).combined.min.js" 2: Lines="@(JSLinesSite)" Overwrite="true" />   In the next post I will cover doing the same, but for a Mercurial repository.

  • A new SQL, a new Analysis Services, a new Workshop! #ssas #sql2012

    - by Marco Russo (SQLBI)
    One week ago Microsoft SQL Server 2012 finally debuted with a virtual launch event and you can find many intro sessions there (20 minutes each). There is a lot of new content available if you want to learn more about SQL 2012 and in this blog post I’d like to provide a few link to sessions, documents, bits and courses that are available now or very soon. First of all, the release of Analysis Services 2012 has finally released PowerPivot 2012 (many of us called it PowerPivot v2 before this official name) and also the new Data Mining Add-in for Microsoft Office 2010, now available also for Excel 64bit! And, of course, don’t miss the Microsoft SQL Server 2012 Feature Pack, there are a lot of upgrades for both DBAs and developers. I just discovered there is a new LocalDB version of SQL Express that can run in user mode without any setup. Is this the end of SQL CE? But now, back to Analysis Services: if you want some tutorial on Tabular, the Microsoft Virtual Academy has a whole track dedicated to Analysis Services 2012 but you will probably be interested also in the one about Reporting Services 2012. If you think that virtual is good but it’s not enough, there are plenty of conferences in the coming months – these are just those where I and Alberto will deliver some SSAS Tabular presentations: SQLBits X, London, March 29-31, 2012: if you are in London or want a good reason to go, this is the most important SQL Server event in Europe this year, no doubts about it. And not only because of the high number of attendees, but also because there is an impressive number of speakers (excluding me, of course) coming from all over the world. This is an event second only to PASS Summit in Seattle so there are no good reasons to not attend it. Microsoft SQL Server & Business Intelligence Conference 2012, Milan, March 28-29, 2012: this is an Italian conference so the language might be a barrier, but many of us also speak English and the food is good! Just a few seats still available. TechEd North America, Orlando, June 11-14, 2012: you know, this is a big event and it contains everything – if you want to spend a whole day learning the SSAS Tabular model with me and Alberto, don’t miss our pre-conference day “Using BISM Tabular in Microsoft SQL Server Analysis Services 2012” (be careful, it is on June 10, a nice study-Sunday!). TechEd Europe, Amsterdam, June 26-29, 2012: the European version of TechEd provides almost the same content and you don’t have to go overseas. We also run the same pre-conference day “Using BISM Tabular in Microsoft SQL Server Analysis Services 2012” (in this case, it is on June 25, that’s a regular Monday). I and Alberto will also speak at some user group meeting around Europe during… well, we’re going to travel a lot in the next months. In fact, if you want to get a complete training on SSAS Tabular, you should spend two days with us in one of our SSAS Tabular Workshop! We prepared a 2-day seminar, a very intense one, that start from the simple tabular modeling and cover architecture, DAX, query, advanced modeling, security, deployment, optimization, monitoring, relationships with PowerPivot and Multidimensional… Really, there are a lot of stuffs here! We announced the first dates in Europe and also an online edition optimized for America’s time zone: Apr 16-17, 2012 – Amsterdam, Netherlands Apr 26-27, 2012 – Copenhagen, Denmark May 7-8, 2012 – Online for America’s time zone May 14-15, 2012 – Brussels, Belgium May 21-22, 2012 – Oslo, Norway May 24-25, 2012 – Stockholm, Sweden May 28-29, 2012 – London, United Kingdom May 31-Jun 1, 2012 – Milan, Italy (Italian language) Also Chris Webb will join us in this workshop and in every date you can find who is the speaker on the web site. The course is based on our upcoming book, almost 600 pages (!) about SSAS Tabular, an incredible effort that will be available very soon in a preview (rough cuts from O’Reilly) and will be on the shelf in May. I will provide a link to order it as soon as we have one! And if you think that this is not enough… you’re right! Do you know what is the only thing you can do to optimize your Tabular model? Optimize your DAX code. Learning DAX is easy, mastering DAX requires some knowledge… and our DAX Advanced Workshop will provide exactly the required content. Public classes will be available later this year, by now we just deliver it on demand.

  • Why AdMob&#8217;s reported iPhone and Android market shares are inflated

    AdMob, the mobile advertiser that was bought by Google some months ago, has released its latest market share figures for the mobile browsers.Their main findings have already been discussed extensively: Smartphones are on the rise; 48% versus 35% last month. Feature phones are falling quickly; 58% to 35%. Still, the absolute number of feature phones rose by 31%, which means that the market as a whole is growing rapidly.The AdMob report, however, is not about browser market share but about ad impressions....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Do most companies not know how to write software?

    - by SnOrfus
    If you're an active reader here, try to think about how many times you've heard (and even agreed) when someone here has told someone else to start looking for a new job. Personally, I've seen it a lot more than I expected: it's almost starting to sound cliche. I get that there are bound to be a number of companies that are bad at developing software or managing a software project, but it almost seems like it's getting worse and more frequent, maybe we're just hearing from them and not all of the places that have decent work atmospheres/conditions. So I ask: In your experience, and through your developer friends do you find that it is common that companies have bad development environments and if so: Why do you think it's common? What do you think could be done to fix it as a developer, as a manager, as an industry? Do you think it's improving?

  • Did "sudo dconf reset -f /org/compiz". Now ccsm settings ignored

    - by bshanks
    I executed: sudo dconf reset -f /org/compiz Now changing settings in CompizConfig Settings Manager (ccsm) has no effect. For example, changing the number of desktops has no effect. I tried purging and reinstalling ccsm but it didn't help. Incidentally, where is the documentation for this sort of thing (which documentation specifies where Unity and Compiz store config settings?)? And where does dconf store things? And where is dconf's documentation? http://dag.wieers.com/home-made/dconf/dconf.1.html says nothing about the 'reset' command, and it says it stores things in /var/log/dconf, but nothing was there. Are there two things named 'dconf'? I would actually like to just put things back to where they were before I executed sudo dconf reset. I have a backup of my hard drive available, I just need to know which files to rollback. I tried rolling back the .config, .gconf, and .cache directories, to no avail. I'm using 12.04.

  • Tuning Red Gate: #4 of Some

    - by Grant Fritchey
    First time connecting to these servers directly (keys to the kingdom, bwa-ha-ha-ha. oh, excuse me), so I'm going to take a look at the server properties, just to see if there are any issues there. Max memory is set, cool, first possible silly mistake clear. In fact, these look to be nicely set up. Oh, I'd like to see the ANSI Standards set by default, but it's not a big deal. The default location for database data is the F:\ drive, where I saw all the activity last time. Cool, the people maintaining the servers in our company listen, parallelism threshold is set to 35 and optimize for ad hoc is enabled. No shocks, no surprises. The basic setup is appropriate. On to the problem database. Nothing wrong in the properties. The database is in SIMPLE recovery, but I think it's a reporting system, so no worries there. Again, I'd prefer to see the ANSI settings for connections, but that's the worst thing I can see. Time to look at the queries, tables, indexes and statistics because all the information I've collected over the last several days suggests that we're not looking at a systemic problem (except possibly not enough memory), but at the traditional tuning issues. I just want to note that, I started looking at the system, not the queries. So should you when tuning your environment. I know, from the data collected through SQL Monitor, what my top poor performing queries are, and the most frequently called, etc. I'm starting with the most frequently called. I'm going to get the execution plan for this thing out of the cache (although, with the cache dumping constantly, I might not get it). And it's not there. Called 1.3 million times over the last 3 days, but it's not in cache. Wow. OK. I'll see what's in cache for this database: SELECT  deqs.creation_time,         deqs.execution_count,         deqs.max_logical_reads,         deqs.max_elapsed_time,         deqs.total_logical_reads,         deqs.total_elapsed_time,         deqp.query_plan,         SUBSTRING(dest.text, (deqs.statement_start_offset / 2) + 1,                   (deqs.statement_end_offset - deqs.statement_start_offset) / 2                   + 1) AS QueryStatement FROM    sys.dm_exec_query_stats AS deqs         CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest         CROSS APPLY sys.dm_exec_query_plan(deqs.plan_handle) AS deqp WHERE   dest.dbid = DB_ID('Warehouse') AND deqs.statement_end_offset > 0 AND deqs.statement_start_offset > 0 ORDER BY deqs.max_logical_reads DESC ; And looking at the most expensive operation, we have our first bad boy: Multiple table scans against very large sets of data and a sort operation. a sort operation? It's an insert. Oh, I see, the table is a heap, so it's doing an insert, then sorting the data and then inserting into the primary key. First question, why isn't this a clustered index? Let's look at some more of the queries. The next one is deceiving. Here's the query plan: You're thinking to yourself, what's the big deal? Well, what if I told you that this thing had 8036318 reads? I know, you're looking at skinny little pipes. Know why? Table variable. Estimated number of rows = 1. Actual number of rows. well, I'm betting several more than one considering it's read 8 MILLION pages off the disk in a single execution. We have a serious and real tuning candidate. Oh, and I missed this, it's loading the table variable from a user defined function. Let me check, let me check. YES! A multi-statement table valued user defined function. And another tuning opportunity. This one's a beauty, seriously. Did I also mention that they're doing a hash against all the columns in the physical table. I'm sure that won't lead to scans of a 500,000 row table, no, not at all. OK. I lied. Of course it is. At least it's on the top part of the Loop which means the scan is only executed once. I just did a cursory check on the next several poor performers. all calling the UDF. I think I found a big tuning opportunity. At this point, I'm typing up internal emails for the company. Someone just had their baby called ugly. In addition to a series of suggested changes that we need to implement, I'm also apologizing for being such an unkind monster as to question whether that third eye & those flippers belong on such an otherwise lovely child.

  • Getting started with Oracle Database In-Memory Part III - Querying The IM Column Store

    - by Maria Colgan
    In my previous blog posts, I described how to install, enable, and populate the In-Memory column store (IM column store). This weeks post focuses on how data is accessed within the IM column store. Let’s take a simple query “What is the most expensive air-mail order we have received to date?” SELECT Max(lo_ordtotalprice) most_expensive_order FROM lineorderWHERE  lo_shipmode = 5; The LINEORDER table has been populated into the IM column store and since we have no alternative access paths (indexes or views) the execution plan for this query is a full table scan of the LINEORDER table. You will notice that the execution plan has a new set of keywords “IN MEMORY" in the access method description in the Operation column. These keywords indicate that the LINEORDER table has been marked for INMEMORY and we may use the IM column store in this query. What do I mean by “may use”? There are a small number of cases were we won’t use the IM column store even though the object has been marked INMEMORY. This is similar to how the keyword STORAGE is used on Exadata environments. You can confirm that the IM column store was actually used by examining the session level statistics, but more on that later. For now let's focus on how the data is accessed in the IM column store and why it’s faster to access the data in the new column format, for analytical queries, rather than the buffer cache. There are four main reasons why accessing the data in the IM column store is more efficient. 1. Access only the column data needed The IM column store only has to scan two columns – lo_shipmode and lo_ordtotalprice – to execute this query while the traditional row store or buffer cache has to scan all of the columns in each row of the LINEORDER table until it reaches both the lo_shipmode and the lo_ordtotalprice column. 2. Scan and filter data in it's compressed format When data is populated into the IM column it is automatically compressed using a new set of compression algorithms that allow WHERE clause predicates to be applied against the compressed formats. This means the volume of data scanned in the IM column store for our query will be far less than the same query in the buffer cache where it will scan the data in its uncompressed form, which could be 20X larger. 3. Prune out any unnecessary data within each column The fastest read you can execute is the read you don’t do. In the IM column store a further reduction in the amount of data accessed is possible due to the In-Memory Storage Indexes(IM storage indexes) that are automatically created and maintained on each of the columns in the IM column store. IM storage indexes allow data pruning to occur based on the filter predicates supplied in a SQL statement. An IM storage index keeps track of minimum and maximum values for each column in each of the In-Memory Compression Unit (IMCU). In our query the WHERE clause predicate is on the lo_shipmode column. The IM storage index on the lo_shipdate column is examined to determine if our specified column value 5 exist in any IMCU by comparing the value 5 to the minimum and maximum values maintained in the Storage Index. If the value 5 is outside the minimum and maximum range for an IMCU, the scan of that IMCU is avoided. For the IMCUs where the value 5 does fall within the min, max range, an additional level of data pruning is possible via the metadata dictionary created when dictionary-based compression is used on IMCU. The dictionary contains a list of the unique column values within the IMCU. Since we have an equality predicate we can easily determine if 5 is one of the distinct column values or not. The combination of the IM storage index and dictionary based pruning, enables us to only scan the necessary IMCUs. 4. Use SIMD to apply filter predicates For the IMCU that need to be scanned Oracle takes advantage of SIMD vector processing (Single Instruction processing Multiple Data values). Instead of evaluating each entry in the column one at a time, SIMD vector processing allows a set of column values to be evaluated together in a single CPU instruction. The column format used in the IM column store has been specifically designed to maximize the number of column entries that can be loaded into the vector registers on the CPU and evaluated in a single CPU instruction. SIMD vector processing enables the Oracle Database In-Memory to scan billion of rows per second per core versus the millions of rows per second per core scan rate that can be achieved in the buffer cache. I mentioned earlier in this post that in order to confirm the IM column store was used; we need to examine the session level statistics. You can monitor the session level statistics by querying the performance views v$mystat and v$statname. All of the statistics related to the In-Memory Column Store begin with IM. You can see the full list of these statistics by typing: display_name format a30 SELECT display_name FROM v$statname WHERE  display_name LIKE 'IM%'; If we check the session statistics after we execute our query the results would be as follow; SELECT Max(lo_ordtotalprice) most_expensive_order FROM lineorderWHERE lo_shipmode = 5; SELECT display_name FROM v$statname WHERE  display_name IN ('IM scan CUs columns accessed',                        'IM scan segments minmax eligible',                        'IM scan CUs pruned'); As you can see, only 2 IMCUs were accessed during the scan as the majority of the IMCUs (44) in the LINEORDER table were pruned out thanks to the storage index on the lo_shipmode column. In next weeks post I will describe how you can control which queries use the IM column store and which don't. +Maria Colgan

  • Looking for enterprise web application design inspiration [closed]

    - by Farshid
    I've checked many websites to be inspired about what the look and feel of a serious enterprise web-application should look like. But the whole I saw were designed for being used by single users and not serious corporate users. The designs I saw were mostly happy-colored, and looked like being developed by a small team of eager young passionate developers. But what I'm looking for, are showcases of serious web apps' designs (e.g. web apps developed by large corporations) that are developed for being used by a large number of corporate uses. Can you suggest me sources for this kind of inspiration?
