• Make is more OOPey - good structure?

  - by Tom

  Hi, I just want advice on whether I could improve structure around a particular class which handles all disk access functions The structure of my program is that I have a class called Disk which gets data from flatfiles and databases on a, you guessed it, hard disk drive. I have functions like LoadTextFileToStringList, WriteStringToTextFile, DeleteLineInTextFile etc which are kind of "generic methods" In the same class I also have some more specific methods such as GetXFromDisk where X might be a particular field in a database table/query. Should I separate out the generic methods from the specialised. Should I make another class which inherits the generic methods. At the moment my class is static as there is no need to have an internal state of the class. I'm not really OOPing am I? Thanks Thomas

• How active record is automatically setting up the autoincremental value of ID?

  - by piemesons

  Here this is what we are doing:-- an_order = Order.new an_order.name = "Dave Thomas" an_order.email = "[email protected]" an_order.address = "123 Main St" an_order.pay_type = "check" an_order.save Now it will insert a new row in orders table right. I m having a ID column in that table. Now suppose after inserting this record the value of the ID corresponding to this record is 100. Now how this 100 value came to know? Does the previous value of ID ie 99 (Suppose) is stored somewhere in some variable/file in the ORM layer or before inserting this value a query was fired to know about the last inserted value or database is itself doing that or anything else???

• search for a winner, returning their rank

  - by incrediman

  Earlier I asked this question, which basically asked how to list 10 winners in a table with many winners, according to their points. This was answered. Now I'm looking to search for a given winner X in the table, and find out what position he is in, when the table is ordered by points. For example, if this is the table: Winners: NAME:____|__POINTS: Winner1 | 1241 Winner2 | 1199 Sally | 1000 Winner4 | 900 Winner5 | 889 Winner6 | 700 Winner7 | 667 Jacob | 623 Winner9 | 622 Winner10 | 605 Winner11 | 600 Winner12 | 586 Thomas | 455 Pamela | 434 Winner15 | 411 Winner16 | 410 These are possible inputs and outputs for what I want to do: Query: "Sally", "Winner12", "Pamela", "Jacob" Output: 3 12 14 623 How can I do this? Is it possible, using only a MySQL statement? Or do I need PHP as well? This is the kind of thing I want: WHEREIS FROM Winners WHERE Name='Sally' LIMIT 1 Ideas?

• NHibernate - EventListener for SaveOrUpdateCopy

  - by t-kehl

  Hi. I do Update with SaveOrUpdateCopy(). Now, I have attached an event for this: this.EventListeners.SaveOrUpdateCopyEventListeners = new IMergeEventListener[] { new AuditableSaveOrUpdateCopyEventListener() }; In the AuditableSaveOrUpdateCopyEventListener, I have inherited from DefaultSaveOrUpdateCopyEventListener and overriden OnMerge(): public class AuditableSaveOrUpdateCopyEventListener : DefaultSaveOrUpdateCopyEventListener { public override void OnMerge(MergeEvent evt) { this.AddAuditableData(evt); base.OnMerge(evt); } public override void OnMerge(MergeEvent evt, System.Collections.IDictionary copyCache) { this.AddAuditableData(evt); base.OnMerge(evt, copyCache); } private void AddAuditableData(MergeEvent evt) { var entity = evt.Original as AuditableEntityBase; if (entity != null) { ... } } } But when I now change properties in entity, they will not be saved to the database. Can someone give me a tip, how I can add my auditable-data for SaveOrUpdateCopy? Thank you. Best Regards, Thomas

• Configuring DSVL to show camera images from Logitech9000 webcam

  - by curryage

  I am trying to view camera feed from a Logitech9000 camera using DSVL(DirectShow Video Library) http://sourceforge.net/projects/dsvideolib/. The xml file currently looks as below: <?xml version="1.0" encoding="UTF-8"?> <dsvl_input xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="C:\Documents and Settings\Thomas\My Documents\projects\ARToolKit &amp; DSVideoLib\ARVideoLib\DsVideoLib\DsVideoLib.xsd"> <camera show_format_dialog="false" friendly_name="Logitech Webcam Pro 9000"> <pixel_format> <RGB24 flip_v="false"/> </pixel_format> </camera> </dsvl_input> However, the image that comes up looks vertically inverted. I tried changing the flip_v value to true in the config above but it did not make any difference. Any suggestions?

• Looking for easy way to analyze var_dump (PHP) on large objects

  - by sdek

  I know (PHP's) var_dump is supposed to be "human readable" and all, but analyzing large objects is just a pain in the neck. I am struggling to make sense of a few of the large objects that are being passed around in a script that we are running. (I know that using xdebug with and IDE is a good idea, but I have not been able to get xdebug to run on this project for some reason - several days lost, ugh). Any ideas on how I can easily digest the contents of a really big var_dump? Any ideas are welcome... Although I am hoping that there is something similar to Thomas Frank's JSON tool (where you just put some code in and it gives a nice graphical representation).

• NHibernate - define where condition

  - by t.kehl

  Hi. In my application the user can defines search-conditions. He can choose a column, set an operator (equals, like, greater than, less or equal than, etc.) and give in the value. After the user clicks on a button and the application should do a search on the database with the condition. I use NHibernate and ask me now, what is the efficientest way to do this with NHibernate. Should I create a query with it like (Column=Name, Operator=Like, Value=%John%) var a = session.CreateCriteria<Customer>(); a.Add(Restrictions.Like("Name", "%John%")); return a.List<Customer>(); Or should I do this with HQL: var q = session.CreateQuery("from Customer where " + where); return q.List<Customer >(); Or is there a more bether solution? Thanks for your help. Best Regards, Thomas

• How do I create a "here document" within a shell function?

  - by BenU

  I'm working my way through William Shotts Jr.'s great The Linux Command Line on my Mac OSX 10.7.5 system. 90% of the linux that Shotts covers is close enough to Darwin that I can figure out or GTEM to figure out what's going on. I've made it to chapter 27 on "Writing Shell Scripts" and am getting hung up creating "here files" within a function. I get an syntax error: unexpected end of file error when I include the following function: report_uptime () { cat <<- _EOF_ <H2>System Uptime</H2> <PRE>$(uptime)</PRE> _EOF_ return } The error goes away if I use the following function placeholder: report_uptime () { return } Also, elsewhere in the script, outside of a function I use the cat << _EOF_ format to create a "here file" with no trouble: cat << _EOF_ <HTML> <HEAD> <TITLE>$TITLE</TITLE> </HEAD> <BODY> <H1>$TITLE</H1> <P>$TIME_STAMP</P> $(report_uptime) $(report_disk_space) $(report_home_space) </BODY> </HTML> _EOF_ If anyone has any idea what I'm doing wrong I would be grateful!

• 100% CPU use when new usb device plugged in - services.exe / Windows Server 2003

  - by Will3265

  On my server I am trying to install a new usb drive but all that happens is that the system starts using huge amounts of processor cycles with services.exe. On closer inspection with process explorer there is a thread called umpnpmgr.dll using most of the services.exe processor time. I left it for a half hour and still nothing happened. Rebooted and tried again, same result. Tried a different usb drive, then a flash drive but still same issue. Tried updating driver but it said the update function was already in action. I have used process explorer to kill the thread now so the server can still perform its intended functions. Any device that was previously installed before this began happening will still work but any device new to the system will not. My question(s) is/are: Is there a way to manually install the device into the registry so Windows thinks it is a previously installed device? Or can this problem be repaired through anything other than a reinstall? To do a reinstall would mean backing up large amounts of data which is hard with a usb drive and insufficient space on all other network machines. Any help would be greatly appreciated. William

• Tom Kyte Budapestre jön!

  - by Lajos Sárecz

  Épp azon tunodöm, hogy blogom olvasói között van-e olyan, aki ne ismerné a asktom.oracle.com oldalt. Gyanítom, hogy kevesen vannak. Bár Tom mostanában elég elfoglaltnak tunik, hiszen népszeru oldalán jelenleg azt kéri, hogy elmaradásai miatt késobb kérdezzenek tole, most csupán a már megválaszolt kérdések böngészésére van lehetoség. Megjegyzem ez sem kis ajándék, ráadásul a mester aktivitását mutatja az az adat, amely a fooldalon látható: Az elmúlt négy hétben 47 új kérdést kapott, elolvasott 532 reakciót és megválaszolt ezek közül 380-at. Csoda, hogy van ideje átruccanni Európába, és eloadást tartani a hazai szakembereknek is. Információim szerint ez olyannyira egyedülálló lehetoség lesz, hogy eddig még ilyen nem volt Magyarországon, másrészt valószínuleg a jövoben nem is nagyon lesz még a régióban sem, mivel egyre inkább az a trend hogy úgynevezett virtual class-okat fog tartani o is, azaz személyesen majd maximum az éves OpenWorld konferencián lehet ot látni egy-egy eloadás erejéig. Áprilisban, Budapesten viszont két teljes napig lehet hallgatni tole a hasznosabbnál hasznosabb tanácsokat. Mik is lesznek ezek? Miért fontos a bind változók használata? Hogyan segíti a teljesítményt, a skálázhatóságot és még a biztonságot is? Hogyan muködik a materializált nézet? Mikor érdemes használni és hogyan lehet a leghasznosabbá tenni? Mikor milyen indexet érdemes használni? Mindenki tisztában van azzal, hogy indexekre szükség van, az már kevésbé egyértelmu mikor melyiket érdemes használni az optimális teljesítmény érdekében. Az eloadáson választ kapunk arra is Tom Kyte-tól, milyen szempontok alapján kell kiválasztani a megfelelo indexelést. Milyen adattárolási formákat érdemes választani? Elsore tán nem is gondolnánk hányféle trükk van az adatok optimális tárolására. Hogy csak a legfontosabbakat említsem: klaszeterezett adatszervezés, index-szervezésu tábla, particionálás, tömörítés. Mikor van szükség az adatok átszervezésére? Mik a legjobb technikák az adatok átszervezésére, hogyan lehet ezt úgy végrehajtani, hogy legkevésbé érintse az alkalmazás felhasználóit? Azt gondolom ezek a témák minden gyakorló rendszergazdának és Oracle fejlesztonek ismerosen csengenek, azonban abban egészen biztos vagyok, hogy mindenki számos újdonságot, hasznos tanácsot kaphat, ha részt vesz Thomas Kyte 2 napos tréningjén. Ja és nem utolsó sorban, egészen biztos, hogy lehetoség lesz kérdezni is Tom-tól! További információ és a regisztráció az Oracle University oldalán érheto el.

• ASP.NET Asynchronous Pages and when to use them

  - by rajbk

  There have been several articles posted about using  asynchronous pages in ASP.NET but none of them go into detail as to when you should use them. I finally found a great post by Thomas Marquardt that explains the process in depth. He addresses a key misconception also: So, in your ASP.NET application, when should you perform work asynchronously instead of synchronously? Well, only 1 thread per CPU can execute at a time.  Did you catch that?  A lot of people seem to miss this point...only one thread executes at a time on a CPU. When you have more than this, you pay an expensive penalty--a context switch. However, if a thread is blocked waiting on work...then it makes sense to switch to another thread, one that can execute now.  It also makes sense to switch threads if you want work to be done in parallel as opposed to in series, but up until a certain point it actually makes much more sense to execute work in series, again, because of the expensive context switch. Pop quiz: If you have a thread that is doing a lot of computational work and using the CPU heavily, and this takes a while, should you switch to another thread? No! The current thread is efficiently using the CPU, so switching will only incur the cost of a context switch. Ok, well, what if you have a thread that makes an HTTP or SOAP request to another server and takes a long time, should you switch threads? Yes! You can perform the HTTP or SOAP request asynchronously, so that once the "send" has occurred, you can unwind the current thread and not use any threads until there is an I/O completion for the "receive". Between the "send" and the "receive", the remote server is busy, so locally you don't need to be blocking on a thread, but instead make use of the asynchronous APIs provided in .NET Framework so that you can unwind and be notified upon completion. Again, it only makes sense to switch threads if the benefit from doing so out weights the cost of the switch. Read more about it in these posts: Performing Asynchronous Work, or Tasks, in ASP.NET Applications http://blogs.msdn.com/tmarq/archive/2010/04/14/performing-asynchronous-work-or-tasks-in-asp-net-applications.aspx ASP.NET Thread Usage on IIS 7.0 and 6.0 http://blogs.msdn.com/tmarq/archive/2007/07/21/asp-net-thread-usage-on-iis-7-0-and-6-0.aspx   PS: I generally do not write posts that simply link to other posts but think it is warranted in this case.

• Good Scoop: The PeopleSoft/IBM Backstory

  - by Brian Dayton

  Sometimes you're searching for something online and you find an unrelated, bonus nugget. Last week I stumbled across an interesting blog post from Chris Heller of a PeopleSoft consulting shop in San Ramon, CA called Grey Sparling. I don't know these guys. But Chris, who apparently used to work on the PeopleTools team, wrote a great article on a pre-acquisition, would-be deal between IBM and PeopleSoft that would have standardized PeopleSoft on IBM technology. The behind-the-scenes perspective is interesting. His commentary on the challenges that the company and PeopleSoft customers would have encountered if the deal had gone through was also interesting: ·         "No common ownership. It's hard enough to get large groups of people to work together when they work for the same company, but with two separate companies it is much, much harder. Even within Oracle, progress on Fusion applications was slow until Thomas Kurian took over Fusion applications in addition to Fusion middleware." ·         "No customer buy-in. PeopleSoft customers weren't asking for a conversion to WebSphere, so the fact that doing that could have helped PeopleSoft stay independent wouldn't have meant much to them, especially since the cost of moving to whatever a "PeopleSoft built on WebSphere" would have been significant." ·         "No executive buy-in. This is related to the previous point, but it's worth calling out separately. If Oracle had walked away and the deal with IBM had gone through, and PeopleSoft customers got put through the wringer as part of WebSphere move, all of the PeopleSoft project teams would be put in the awkward position of explaining to their management why these additional costs and headaches were happening. Essentially they would need to "sell" the partnership internally to their own management team. That's not a fun conversation to have." I'm not surprised that something like this was in the works. But I did find the inside scoop and Heller's perspective on the challenges particularly interesting. Especially the advantages of aligning development of applications and infrastructure development under one roof. Here's a link to the whole blog entry.

• The 2010 Life Insurance Conference - Washington, DC

  - by [email protected]

  How ironic to be in Washington, DC on April 15 - TAX DAY! Fortunately, I avoided IRS offices and attended the much more enjoyable 2010 Life Insurance Conference, presented by LIMRA, LOMA SOA and ACLI. This year's conference offered a variety of tracks focused on the Life Industry including Distribution/Marketing Marketing, Administration, Actuarial/Product Development, Regulatory, Reinsurance and Strategic Management. President and CEO of the ACLI, Frank Keating, opened the event by moderating a session titled "Executive Viewpoint on new Opportunities." Guest speakers included Ted Mathas, President and CEO of NY Life, and John Walters, President and CEO of Hartford Life. Both speakers were insightful as they shared the challenges and opportunities each company faces and the key role life insurance companies play in our society and the global economy. There were several key themes that were reiterated in multiple sessions throughout the conference - the economy is on the rebound, optimism is growing, consumer spending is up and an uptick in employment is likely to follow. The threat of a double dip recession has seemed to passed. Good news for our industry, and welcomed by all in attendance. Of special interest to me, given my background, was some research shared by both The Nolan Group and Novarica in separate sessions. Both firms indicate that policy administration upgrades/replacement projects remain a top priority in 2010. Carriers continue to invest in modern technology. Modern ultra-configurable systems enable carriers to switch from a waterfall to an agile project methodology, which often entails a "culture change" within an organization. Other themes heard throughout the two-day event: Virtually all sessions focused on People, Process and Technology! Product innovation, agility and speed to market are as important as ever. Social Networks and Twitter are becoming more popular ways of communicating with both field and dispersed staff. Several sessions focused on the application, new business and underwriting process. Companies continue looking for ways to increase market agility, accelerate speed to market, address cost issues and improve service levels across the process. They recognize the need to ease the way to do business with both producers and consumers. Author and economic futurist Jeff Thredgold presented an entertaining, informative and humorous general session on Wednesday afternoon that focused on the US and global economies, financial markets and retirement outlook. Thredgold did not disappoint anyone with his message! The Thursday morning general session was keynoted by Therese Vaughan (CEO - NAIC) and Thomas Crawford (President of C2 Group). Both speakers gave a poignant view of the recent financial crisis and discussed "Putting the Pieces Back Together." Therese spoke of the recent financial turmoil and likely changes to regulations to the financial services sector. Tom's topics focused on economic recovery and the political environment in Washington, and how that impacts our industry. Next year's event will be April 11-13, 2011 in Las Vegas. Roger A.Soppe, CLU, LUTCF, is the Senior Director of Insurance Strategy, Oracle Insurance.

• Digital Storage for Airline Entertainment

A weak charge will allow a strong current to flow through. Similar to HDDs, flash memory must provide: Bit error correction Bad block management NAND and NOR memories are treated differently when it comes to managing wear In many NOR-based systems no management is used at all, since the NOR is simply used to store code, and data is stored in other devices. In this case, it would take a near-infinite amount of time for wear to become an issue since the only time the chip would see an erase/write cycle is when the code in the system is being upgraded, which rarely if ever happens over the life of a typical system. NAND is usually found in very different application than is NOR Flash memory wears out This is expected to get worse over time Retention: Disappearing data Bits fade away Retention decreases with increasing read/writes Bits may change when adjacent bits are read Time and traffic are concerns Controllers typically groom read disturb errors Like DRAM refresh Increases erase/write frequency Application characteristics Music – reads high / writes very low Video – r high / writes very low Internet Cache – r high / writes low On airplanes Many consumers now have their own content viewing devices – do they need the airlines? Is there a way to offer more to consumers, especially with their own viewers Additional special content tie into airplane network access to electrical power, internet Should there be fixed embedded or removable storage for on-board airline entertainment? Is there a way to leverage personal and airline viewers and content in new and entertaining ways?

• The Niantic Project: Ingress by Felicia Hajra-Lee

  Despite the current fact that the augmented reality game for Android is still in beta phase, it is amazing to see that the world of literature is already taking momentum on this 'real-life' universe. After reading 'The Alignment: Ingress' by Thomas Greanias it took only a blink of the eye to go for 'The Niantic Project: Ingress' by Felicia Hajra-Lee, too. Here is the review I posted on Amazon.com: Ingress, a parallel universe to our reality, is here. There is no doubt about this anymore... The Niantic Project, originated at the CERN collider in Geneva, Switzerland, got into focus of global players. And the game is hard; fair-play is only for the fainted ones. Felicia understands to drag the audience directly into the action of the Niantic Project and its protagonists. The novella is heavily based on the investigations posted daily on the website of Ingress. She really understands how to interweave the various clues and creates an atmosphere where it sometimes feels challenging to differentiate between fiction and reality. It all starts with 'Epiphany Night' at the Niantic Labs, the high exposure of Exotic Matter (XM) and the escape of scientist Dr. Devra Bogdanovich and 'sentinel' Roland Jarvis. Of course, a new research, or should we name it technology, like the Niantic Project has to be protected and there are multiple parties on the hunt. Throughout the various chapters Felicia introduces new potential buyers from all over the globe, gives us detailed insights on the hunters and their brutal effectiveness to finish an assignment, and manages to keep the reader in high-pitched mode thanks to a couple of turn-arounds in the overall story. Personally, I have to say that I really enjoyed reading this title. Felicia's love to details is absolutely amazing, and sometimes I was really wondering whether she would be one of the assassins. But unfortunately I also have to say that I'm not a great fan of the structural organization of the (title-less) chapters. It is fascinating to follow the ventures of Devra, Farlowe and 855 but occasionally I had to go back to previous paragraphs in order to keep track of the individual plots. Overall a great title, captivating and rich in details but simply too short. Please Fecilia, gives us more to read. As an owner of an Android smartphone or tablet, you should get yourself into the world of Ingress. Check out the Play Store to install the app. Now. ;-)

• Managing Social Relationships for the Enterprise – Part 1

  - by Michael Hylton

  v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Reggie Bradford, Senior Vice President, Oracle Today, Mark Hurd, President of Oracle, Thomas Kurian, Executive Vice President of Oracle and I discussed the strategic importance of how social media is impacting the enterprise and how it is changing the way customers, prospects employees and investors interact with brands worldwide. Oracle understands that the consumer is in control and as such, brands must evolve and change to meet growing needs. In addition, according to social media thought leader and Analyst from Altimeter Group, Jeremiah Owyang, companies now average 178 corporate-owned social media accounts. When Oracle added leading social marketing, listening analytics and development tools from Vitrue, Collective Intellect and Involver to its Oracle’s Cloud Services Suite we went beyond providing a single set of tools. We developed an entire framework to include a comprehensive social relationship management suite to help companies move beyond the social enterprise and achieve the social-enabled enterprise. The fundamental shift from transaction to engagement means that enterprises need not only a social strategy, but should also ensure that the information and data received from social initiatives flow back to marketing, sales, support and service. Doing so enables companies to deliver a proactive and compelling experience and provides analytics to turn engagement into opportunity – and ultimately that opportunity into revenue. On September 13, 2012, I am delighted to sit down with Jeremiah to further the discussion about how enterprises are addressing social media strategies and managing content. In addition, we will be taking your questions after the webinar via Twitter (@Oracle, @ReggieBradford, @cwfinn, @jowyang). Use #oracle and #socbiz to submit questions and follow the conversation. I look forward to speaking with you and answering your questions online. For more information about becoming a social-enabled enterprise, visit www.oracle.com/social.

• Fast Data: Go Big. Go Fast.

  - by J Swaroop

  Cross-posting Dain Hansen's excellent recap of the Big Data/Fast Data announcement during OOW: For those of you who may have missed it, today’s second full day of Oracle OpenWorld 2012 started with a rumpus. Joe Tucci, from EMC outlined the human face of big data with real examples of how big data is transforming our world. And no not the usual tried-and-true weblog examples, but real stories about taxi cab drivers in Singapore using big data to better optimize their routes as well as folks just trying to get a better hair cut. Next we heard from Thomas Kurian who talked at length about the important platform characteristics of Oracle’s Cloud and more specifically Oracle’s expanded Cloud Services portfolio. Especially interesting to our integration customers are the messaging support for Oracle’s Cloud applications. What this means is that now Oracle’s Cloud applications have a lightweight integration fabric that on-premise applications can communicate to it via REST-APIs using Oracle SOA Suite. It’s an important element to our strategy at Oracle that supports this idea that whether your requirements are for private or public, Oracle has a solution in the Cloud for all of your applications and we give you more deployment choice than any vendor. If this wasn’t enough to get the juices flowing, later that morning we heard from Hasan Rizvi who outlined in his Fusion Middleware session the four most important enterprise imperatives: Social, Mobile, Cloud, and a brand new one: Fast Data. Today, Rizvi made an important step in the definition of this term to explain that he believes it’s a convergence of four essential technology elements: Event Processing for event filtering, business rules – with Oracle Event Processing Data Transformation and Loading - with Oracle Data Integrator Real-time replication and integration – with Oracle GoldenGate Analytics and data discovery – with Oracle Business Intelligence Each of these four elements can be considered (and architect-ed) together on a single integrated platform that can help customers integrate any type of data (structured, semi-structured) leveraging new styles of big data technologies (MapReduce, HDFS, Hive, NoSQL) to process more volume and variety of data at a faster velocity with greater results.  Fast data processing (and especially real-time) has always been our credo at Oracle with each one of these products in Fusion Middleware. For example, Oracle GoldenGate continues to be made even faster with the recent 11g R2 Release of Oracle GoldenGate which gives us some even greater optimization to Oracle Database with Integrated Capture, as well as some new heterogeneity capabilities. With Oracle Data Integrator with Big Data Connectors, we’re seeing much improved performance by running MapReduce transformations natively on Hadoop systems. And with Oracle Event Processing we’re seeing some remarkable performance with customers like NTT Docomo. Check out their upcoming session at Oracle OpenWorld on Wednesday to hear more how this customer is using Event processing and Big Data together. If you missed any of these sessions and keynotes, not to worry. There's on-demand versions available on the Oracle OpenWorld website. You can also checkout our upcoming webcast where we will outline some of these new breakthroughs in Data Integration technologies for Big Data, Cloud, and Real-time in more details.

• SQL SERVER – BI Quiz Hint – Performance Tuning Cubes – Hints

  - by pinaldave

  I earlier wrote about SQL BI Quiz over here and here. The details of the quiz is here: Working with huge data is very common when it is about Data Warehousing. It is necessary to create Cubes on the data to make it meaningful and consumable. There are cases when retrieving the data from cube takes lots of the time. Let us assume that your cube is returning you data very quickly. Suddenly on one day it is returning the data very slowly. What are the three things will you to diagnose this. After diagnose what you will do to resolve performance issue. Participate in my question over here I required BI Expert Jason Thomas to help with few hints to blog readers. He is one of the leading SSAS expert and writes a complicated subject in simple words. If queries were executing properly before but now take a long time to return the data, it means that there has been a change in the environment in which it is running. Some possible changes are listed below:-  1) Data factors:- Compare the data size then and now. Increase in data can result in different execution times. Poorly written queries as well as poor design will not start showing issues till the data grows. How to find it out? (Ans : SQL Server profiler and Perfmon Counters can be used for identifying the issues and performance  tuning the MDX queries)  2) Internal Factors:- Is some slow MDX query / multiple mdx queries running at the same time, which was not running when you had tested it before? Is there any locking happening due to proactive caching or processing operations? Are the measure group caches being cleared by processing operations? (Ans : Again, profiler and perfmon counters will help in finding it out. Load testing can be done using AS Performance Workbench (http://asperfwb.codeplex.com/) by running multiple queries at once)  3) External factors:- Is some other application competing for the same resources?  HINT : Read “Identifying and Resolving MDX Query Performance Bottlenecks in SQL Server 2005 Analysis Services” (http://sqlcat.com/whitepapers/archive/2007/12/16/identifying-and-resolving-mdx-query-performance-bottlenecks-in-sql-server-2005-analysis-services.aspx) Well, these are great tips. Now win big prizes by participate in my question over here.

• Good Scoop: The PeopleSoft/IBM Backstory

  - by [email protected]

  Sometimes you're searching for something online and you find an unrelated, bonus nugget. Last week I stumbled across an interesting blog post from Chris Heller of a PeopleSoft consulting shop in San Ramon, CA called Grey Sparling. I don't know these guys. But Chris, who apparently used to work on the PeopleTools team, wrote a great article on a pre-acquisition, would-be deal between IBM and PeopleSoft that would have standardized PeopleSoft on IBM technology. The behind-the-scenes perspective is interesting. His commentary on the challenges that the company and PeopleSoft customers would have encountered if the deal had gone through was also interesting: ·         "No common ownership. It's hard enough to get large groups of people to work together when they work for the same company, but with two separate companies it is much, much harder. Even within Oracle, progress on Fusion applications was slow until Thomas Kurian took over Fusion applications in addition to Fusion middleware." ·         "No customer buy-in. PeopleSoft customers weren't asking for a conversion to WebSphere, so the fact that doing that could have helped PeopleSoft stay independent wouldn't have meant much to them, especially since the cost of moving to whatever a "PeopleSoft built on WebSphere" would have been significant." ·         "No executive buy-in. This is related to the previous point, but it's worth calling out separately. If Oracle had walked away and the deal with IBM had gone through, and PeopleSoft customers got put through the wringer as part of WebSphere move, all of the PeopleSoft project teams would be put in the awkward position of explaining to their management why these additional costs and headaches were happening. Essentially they would need to "sell" the partnership internally to their own management team. That's not a fun conversation to have." I'm not surprised that something like this was in the works. But I did find the inside scoop and Heller's perspective on the challenges particularly interesting. Especially the advantages of aligning development of applications and infrastructure development under one roof. Here's a link to the whole blog entry.

• Invitation til Oracle Open Experience DK11

  - by user13847369

  Kære Partnere, Vi afholder sammen med Arrow et større kundearrangement den 7. December ved navnet "Oracle Open Experience DK11". I kan se agendaen for dagen her: V. Torben Markussen, Sales director/Middleware director Nordics, Oracle Fornem stemningen fra årets OpenWorld og få præsenteret de største og mest relevante nyheder. Hør hvordan I drager konkret fordel af Oracle-nyheder som Oracle Cloud, storageløsningen Pillar Axiom og de unikke nye muligheder med Fusion Applications. V. Hans Bøge, IT-arkitekt, Oracle Hans Bøge fortæller om hvordan I optimerer jeres licensløsning, og letter administrationen af jeres database. En server fødes med adskillige cores - alle med licensomkostninger. Hvorfor ikke nøjes med at aktivere det antal der matcher jeres behov? Hør hvordan I får en løsning, der kan opgraderes hen ad vejen som behovene opstår. V. Kim Estrup, Produktchef 11G , Oracle Brugerdefinerede implementeringer gør jeres systemer unikke, hvilket kun øger komplek og administration. Kim Estrup vil fortælle alt om, hvordan I letter forvaltningen af jeres traditionelle data-centre, samt etablerer lynhurtig adgang til skyen. Få indføring i en omfattende løsning, der skærer gennem kompleksitet, øger service-kvalitet og minimerer administrations- omkostninger. V. Steen Schmidt, IT-arkitekt, Oracle Hør hvordan de nyeste teknologier indenfor virtualisering og server-management, kan forsimple jeres IT-processer og reducere omkostninger markant. Få demonstreret en løsn der er fire gange mere skalerbar end den seneste VWware, og som kan understøtte op  til 128 virtuelle CPUer per virtuel maskine - endda til en brøkdel af omkostningen. Steen Schmidt fortæller alt om mulighederne i jeres storagesystem V. Erik Lund, Storage Presales-arkitekt, Oracle Lyder det for godt til at være sandt? Det kan faktisk lade sig gøre. Erik Lund fortæller alt om de nyeste storage-teknologier, der åbner op for skalerbarhed på både disc- og controllerniveau, og for database-komprimering med op til faktor 50. Det reducerer behovet for discs og formindsker jeres backup-vindue markant. Kombineret med markedets højeste udnyttelsesgrad og omkostningsfri QoS, giver det helt nye muligheder. Dagen starter kl 8.30 med morgenmad og slutter kl 14.00 Jeg håber I har lyst til at deltage samt at invitere jeres kunder.I skulle gerne have modtaget en invitation som I også kan bruge til at sende ud til jeres kunder.Er det ikke tilfældet så send mig endeligt en mail. Du kan også tilmelde dig via dette link: http://www.woho.dk/oracle og indtaste billetnummer: 1500Mvh Thomas Stenvald
