  • Autoscaling in a modern world&hellip;. Part 4

    - by Steve Loethen
    Now that I have the rules and services XML files in the cloud, it is time to sever the bounds of earth and live totally in the cloud.  I have to host the Autoscaling object in Azure as well, point it to the rules, tell it the management certs and get out of the way. A couple of questions.  Where to host?  The most obvious place to me was a worker role.  A simple, single purpose worker role, doing nothing but watching my app.  Here are the steps I used. 1) Created a project.  Separate project from my web site.  I wanted to be able to run the web in the cloud and the autoscaler local for debugging purposes.  Seemed like the easiest way.  2) Add the Wasabi block to the project. 3) Configure the settings.  I used the same settings used for the console app.  It points to the same web role, uses the same rules file.  4) Make sure the certification needed to manage the role is added to the cert store in the sky (“LocalMachine” and “My” are default locations). I ran the worker role in the local fabric.  It worked.  I then published to the cloud, and verified it worked again.  Here is what my code looked like. public override bool OnStart() { Trace.WriteLine("Set Default Connection Limit", "Information"); // Set the maximum number of concurrent connections ServicePointManager.DefaultConnectionLimit = 12; Trace.WriteLine("Set up configuration change code", "Information"); // set up config CloudStorageAccount.SetConfigurationSettingPublisher((configName, configSetter) => configSetter(RoleEnvironment.GetConfigurationSettingValue(configName))); Trace.WriteLine("Get current diagnostic configuration", "Information"); // Get current diagnostic configuration DiagnosticMonitorConfiguration dmc = DiagnosticMonitor.GetDefaultInitialConfiguration(); Trace.WriteLine("Set Diagnostic Buffer Size", "Information"); // Set Diagnostic Buffer size dmc.Logs.BufferQuotaInMB = 4; Trace.WriteLine("Set log transfer period", "Information"); // Set log transfer period dmc.Logs.ScheduledTransferPeriod = TimeSpan.FromMinutes(1); Trace.WriteLine("Set log verbosity", "Information"); // Set log filter to verbose dmc.Logs.ScheduledTransferLogLevelFilter = LogLevel.Verbose; Trace.WriteLine("Start the diagnostic monitor", "Information"); // Start the diagnostic monitor DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString", dmc); Trace.WriteLine("Get the current Autoscaler from the EntLib Container", "Information"); // Get the current Autoscaler from the EntLib Container scaler = EnterpriseLibraryContainer.Current.GetInstance<Autoscaler>(); Trace.WriteLine("Start the autoscaler", "Information"); // Start the autoscaler scaler.Start(); Trace.WriteLine("call the base class OnStart", "Information"); // call the base class OnStart return base.OnStart(); } public override void OnStop() { Trace.WriteLine("Stop the Autoscaler", "Information"); // Stop the Autoscaler scaler.Stop(); } I did have to turn on some basic logging for wasabi, which will cover in the next post.  This let me figure out that I hadn’t done the certificate step.

  • CCNet TFS Migration - Dealing with left over folders

    - by Michael Stephenson
    Im currently in the process of migrating our many BizTalk projects from MKS source control to TFS.  While we will be using TFS for work item tracking and source control etc we will be continuing to use Cruise Control for continuous integration although im updating this to CCNet 1.5 at the same time. Ill post a few things as much as a reminder to myself about some of the problems we come across. Problem After the first build of our code the next time a build is triggered an error is encountered by the TFS source control block refreshing the source code. System.IO.IOException: The directory is not empty.    at System.IO.Directory.DeleteHelper(String fullPath, String userPath, Boolean recursive)    at System.IO.Directory.Delete(String fullPath, String userPath, Boolean recursive)    at ThoughtWorks.CruiseControl.Core.Sourcecontrol.Vsts.deleteDirectory(String path)    at ThoughtWorks.CruiseControl.Core.Sourcecontrol.Vsts.GetSource(IIntegrationResult result)    at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Build(IIntegrationResult result)    at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Integrate(IntegrationRequest request) System.IO.IOException: The directory is not empty. at System.IO.Directory.DeleteHelper(String fullPath, String userPath, Boolean recursive) at System.IO.Directory.Delete(String fullPath, String userPath, Boolean recursive) at ThoughtWorks.CruiseControl.Core.Sourcecontrol.Vsts.deleteDirectory(String path) at ThoughtWorks.CruiseControl.Core.Sourcecontrol.Vsts.GetSource(IIntegrationResult result) at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Build(IIntegrationResult result) at ThoughtWorks.CruiseControl.Core.IntegrationRunner.Integrate(IntegrationRequest request) Project: Bupa.BPI.Documents Date of build: 2011-01-28 14:54:21 Running time: 00:00:05 Integration Request: Build (ForceBuild) triggered from VMOPBZDEV11 Solution The problem seems to be with a folder called TestLocations which is created by the build process and used along with the file adapter as a way to get messages into BizTalk.  For some reason the source control block when it does a full refresh of the code does not get rid of this folder and then complains thats a problem and fails the build. Interestingly there are other folders created by the build which are deleted fine.  My assumption is that this if something to do with the file adapter polling the directory.  However note that we have not had this problem with other source control blocks in the past. To workaround this I have added a prebuild task to the ccnet.config file to delete this folder before the source control block is executed.  See below for example < prebuild> exec>executable>cmd.exe</executable>buildArgs>/c "if exist "C:\<MyCode>\TestLocations" rd /s /q "C:\<MyCode>\TestLocations""</buildArgs>exec> prebuild> < < < </ </

  • Extending UPK with Enablement Packs

    - by bill.x.miller
    We've mentioned in earlier posts that UPK Development keeps the tool up to date through the use of Enable Service Packs (ESP'S). Regular releases ensure that the UPK Developer supports updates to targeted applications as well as new Java updates. Installing an ESP is quick and easy. • Download the latest ESP from My Oracle Support (requires a My Oracle Support account). • Run the setup for each client machine that uses the UPK Developer • Run the Library Updates from one of the clients (multi-user only) Enablement Pack 1 for UPK 3.6.1 contains new features such as a new Tabbed Gateway, FireFox 3.6 support for the Player and SmartHelp, and several new target application versions. But a very exciting feature that is part of this ESP is now available to all Oracle E-Business Suite customers. Until now, a requirement for EBS customers who wish to record UPK content is to install delivered library files (CUSTOM.pll and ODPN.pll) on to the Oracle Application Server. These files were required to present context information to the UPK Developer so that content can be launched in a context sensitive manner. This requirement involved the Oracle system administrator to transfer, install and compile these libraries into the system. Usually a simple process, however, we understood the need to streamline the procedure. With ESP 1 for UPK 3.6.1, these pll files are no longer required. Now, a simple procedure from within the EBS application can make context available to the UPK recorder. From the System Profile, search for UPK: Change the Site field to Enable UPK Recording. Save the Form. Context information will now be made available to the UPK Recorder without involving the System Administrator or DBA. The setting you see here makes context available to all client machines recording content with UPK and does not affect the performance of your EBS application.

  • BIP BIServer Query Debug

    - by Tim Dexter
    With some help from Bryan, I have uncovered a way of being able to debug or at least log what BIServer is doing when BIP sends it a query request. This is not for those of you querying the database directly but if you are using the BIServer and its datamodel to fetch data for a BIP report. If you have written or used the query builder against BIServer and when you run the report it chokes with a cryptic message, that you have no clue about, read on. When BIP runs a piece of BIServer logical SQL to fetch data. It does not appear to validate it, it just passes it through, so what is BIServer doing on its end? As you may know, you are not writing regular physical sql its actually logical sql e.g. select Jobs."Job Title" as "Job Title", Employees."Last Name" as "Last Name", Employees.Salary as Salary, Locations."Department Name" as "Department Name", Locations."Country Name" as "Country Name", Locations."Region Name" as "Region Name" from HR.Locations Locations, HR.Employees Employees, HR.Jobs Jobs The tables might not even be a physical tables, we don't care, that's what the BIServer and its model are for. You have put all the effort into building the model, just go get me the data from where ever it might be. The BIServer takes the logical sql and uses its vast brain to work out what the physical SQL is, executes it and passes the result back to BIP. select distinct T32556.JOB_TITLE as c1, T32543.LAST_NAME as c2, T32543.SALARY as c3, T32537.DEPARTMENT_NAME as c4, T32532.COUNTRY_NAME as c5, T32577.REGION_NAME as c6 from JOBS T32556, REGIONS T32577, COUNTRIES T32532, LOCATIONS T32569, DEPARTMENTS T32537, EMPLOYEES T32543 where ( T32532.COUNTRY_ID = T32569.COUNTRY_ID and T32532.REGION_ID = T32577.REGION_ID and T32537.DEPARTMENT_ID = T32543.DEPARTMENT_ID and T32537.LOCATION_ID = T32569.LOCATION_ID and T32543.JOB_ID = T32556.JOB_ID ) Not a very tough example I know but you get the idea. How do I know what the BIServer is up to? How can I find out what the issue might be if BIServer chokes on my query? There are a couple of steps: In the Administrator tool you need to set the logging level for the Administrator user to something greater than the default '0'. '7' is going to give you the max. Just remember to take it back down after you have finished the debug. I needed to bounce my BIServer service Now here's the secret sauce. Prefix the following to your BIP query set variable LOGLEVEL = 7; Set the log level to that you have in the admin tool Now run your BIP report. With the prefix in place; BIServer will write to the NQQuery.log file. This is located in the ./OracleBI/server/Log directory. In there you are going to find the complete process the BIServer has gone through to try and get the data back for you A quick note, if the BIServer can, its going to hit that great BIEE cache to get your data and you may not see the full log. IF this is the case. Get inot hte Administration page (via the browser login) and clear out your BIP report cursor. Then re-run. This will hopefully help out if you are trying to debug that annoying BIP report that will not run or is getting some strange data. Don't forget to turn that logging level back down once you are done. This will avoid the DBA screaming at you for sucking up all the disk space on the system.

  • Oracle Introduces Oracle Communications Data Model to Provide Actionable Insight for Communications

    - by kimberly.billings
    To help communications service providers (CSPs) manage and analyze rapidly growing data volumes cost effectively, Oracle recently introduced the Oracle Communications Data Model (OCDM). With the OCDM, CSPs can achieve rapid time to value by quickly implementing a standards-based enterprise data warehouse that features communications industry-specific reporting, analytics and data mining. The combination of the OCDM, Oracle Exadata and the Oracle Business Intelligence (BI) Foundation represents the most comprehensive data warehouse and BI solution for the communications industry. Hong Kong Broadband Network, the fastest growing and second largest broadband service provider in Hong Kong, enhanced its data warehouse using Oracle Communications Data Model. It went live with OCDM within three months, and has increased its subscriber base by 37 percent in six months and reduced customer churn to less than one percent. Read more about HKBN's use of OCDM. Read more about OCDM var gaJsHost = (("https:" == document.location.protocol) ?

  • security stuff's

    http://fmwdocs.us.oracle.com/doclibs/fmw/E10285_01/appslib7/web.1111/b31974/adding_security.htm#BGBGJEAH At design time, JDeveloper saves all policy store and identity store changes in a single file for the entire application. In the development environment, this is the jazn-data.xml file. After you configure the jazn-data.xml file using the editors, you can run the application in Integrated WebLogic Server and the contents of the policy store will be added to the domain-level store, the system-jazn-data.xml file, while the test users will be migrated to the embedded LDAP server that Integrated WebLogic Server uses for its identity store. The domain-level store allows you to test the security implementation by logging on as test users that you have created. looks like above part did went well with me, apart from following all instruction provided in doc, I need to create users from adminconsole in security-realms-Users and Groups sections to successfully login to pages.

  • Why Oracle Delivers More Value than IBM in Data Integration Solutions

    - by irem.radzik(at)oracle.com
    For data integration projects, IT organization look for a robust but an easy-to-use solution, which simplifies enterprise data architecture while providing exceptional value-- not one that adds complexity and costs. This is a major challenge today for customers who are using IBM InfoSphere products like DataStage or Change Data Capture. Whereas, Oracle consistently delivers higher level value with its data integration products such as Oracle Data Integrator, Oracle GoldenGate. There are many differentiators for Oracle's Data Integration offering in comparison to IBM. Here are the top five: Lower cost of ownership Higher performance in both real-time and bulk data movement Ease of use and flexibility Reliability Complete, Open, and Integrated Middleware Offering Architectural differences between products contribute a great deal to these differences. First of all, Oracle's ETL architecture does not require a middle-tier transformation server, something IBM does require. Not only it costs more to manage an additional transformation server including energy costs, but it adds a performance bottleneck as well. In addition, IBM's data integration products are complex and often require lengthy professional services engagements to integrate. This translates to higher costs and delayed time to market. Then there's the reliability factor. Our customers choose Oracle GoldenGate over IBM's InfoSphere Change Data Capture product because Oracle GoldenGate is designed for mission-critical systems that require guaranteed data delivery and automatic recovery in case of process interruptions. On Thursday we will discuss these key differentiators in detail and provide customer examples that chose Oracle over IBM in data integration projects. Join us on Thursday Feb 10th at 11am PT to learn how Oracle delivers more value than IBM in data integration solutions.

Now in its fourteenth year, The BI Survey regularly attracts around 3000 responses from a global audience. It provides an invaluable resource to companies deciding which software to select and to vendors who want to understand the needs of the market. The Survey is funded by its readers, not by the participant vendors. As with the previous thirteen editions, no vendors have been involved in any way with the formulation of The BI Survey. Unlike most other surveys, it is not commissioned, sponsored or influenced by vendors. Here is a link to the survey: https://digiumenterprise.com/answer/?link=1981-ZYQSEY8B If you take the survey you will get access to a summary of the results. By helping to promote the survey here I'll get access to some more detailed results including some country specific analysis so it will be interesting to see the results.

  • Are You Afraid of Each Other? Study Shows CMO’s/CIO’s Missing Benefits of Collaboration

    - by Mike Stiles
    Remember that person in school you spent months being too scared to talk to?  Then when you finally did, it led to a wonderful friendship…if not something more. New research from Oracle, Social Media Today and Leader Networks shows marketing and IT need to get over whatever’s holding them back and start reaping the benefits of collaboration. Back in the old days of just a few years ago, marketing could stay on their side of the building, IT could stay on their side of the building, and both could refer to the other as “those guys.” Today, the structure of organizations is shifting from islands to “us,” one integrated body where each part knows what the other parts are doing, and all parts work together in accomplishing job one…a winning customer experience. Ignore that, and you start losing. Give your reluctance to change priority over the benefits of new collaborations, and you start losing. You’re either working together and accelerating forward or getting in the way of each other’s separate agendas and grinding down…much to your competitors’ delight. The study reveals a basic current truth: those who are collaborating in marketing and IT report being more effective, however less than 1/3 report collaborating even “frequently.” In other words, this is obviously a good thing, so we’d better not do it. Smart. The white paper, “Socially Driven Collaboration,” set out to explore how today’s always-changing digital, social and mobile landscape is forcing change across the enterprise, whether it’s welcomed or not. Part of what it found is marketing and IT leaders are not unaware of what’s going on and see their roles evolving. And both know the ability to collaborate more effectively now exists. And of those who are collaborating, over 2/3 say they’re “more effective” professionally because of it. Yet even if you don’t want to take the Oracle study’s word for it, an August 2013 Accenture study of 400 senior marketing and 250 IT executives revealed only 10% think CMO/CIO collaboration is at the right level. There’s a lot of room for improvement here, and not just around people. Collaboration is also being called for across processes and technologies. Business benefits of such collaboration cited in the Oracle study include stronger marketing messages, faster speed-to-market, greater product adoption, faster discovery of product and service shortcomings, and reduction in project costs. Those are the benefits you will cheat yourself out of by keeping “those guys” at arm’s length and continuing to try to function in traditional roles while modern business and the consumer is changing around you. “Intelligence is the ability to adapt to change.” –Stephen Hawking @mikestilesPhoto: istockphoto

    Just found a good (looks like) tool for jQuery coding and debugging from the appinn.com (Chinese) named jQueryPad by Paul Stovell. With it we don’t need to switch between the visual studio and the browser when coding and debugging. There’s only one main screen where we can type the HTML and jQuery code and just press F5 to see the result in the bottom frame. .NET Frameworks 3.5 is required.   Hope this helps.

  • Meet our 2009 Oracle Graduates in South Africa

    - by anca.rosu
    Focusing on the broader Oracle community, Oracle South Africa initiated its first skills development programme in May 1988. Since its inception the programme has developed and improved and every year more graduates are taken on board. The Oracle Graduate Programme is made up of specific learning paths designed around customer, partner and Oracle specifications and is structured to meet the urgent skills requirements in the Oracle “economy”. The training programmes have a specific duration and incorporate both theoretical and practical application of Oracle product sets. It is aimed at creating: Meaningful employment for graduates; Learning opportunities for individuals within the organization so that career growth opportunities are exploited to the fullest; Capacity building for small enterprises which is aligned to Oracle’s Enterprise Development Programme Meet our five graduates who joined us in December 2008 and have spent over a year with us! Let’s get their initial feedback on the graduate programme and on their assignment to Jordan. Lector   On the Oracle Graduate Programme: “The Oracle Graduate Programme is an experience of a life time. I would not trade it for anything. It’s challenging and rewarding. I am proud and happy to be in an organization like Oracle” On the assignment in Jordan: "Friendly, welcoming people, world class instructors always willing to go the extra mile. What more can you ask for?"   Lungile On the Oracle Graduate Programme: “I joined Oracle as part of the graduate intake for pre-sales in order to develop my skills and knowledge. Working at Oracle has been an overwhelmingly positive experience as it has encouraged me to progress with my personal development. I am hugely grateful. It has been a great challenge and an awesome opportunity.” On the assignment to Jordan: “Going to Jordan was a great opportunity and the experience of a lifetime. The people were very welcoming and friendly. The culture was totally different from ours - the food, the clothes and the weather. It was an amazingly different experience to work from Sunday to Thursday with Friday and Saturday as the weekend.” Thabo On the Oracle Graduate Programme: “Life is an infinite learning path. I truly value growth. I believe for one to grow, one needs to be challenged to your full potential. The Oracle Graduate Programme offers real growth – and so much more.” On the assignment to Jordan: “I was amazed by the cultural differences. I now understood that to be part of the global community, I must embrace our similarities and understand our differences.”   Albeauty On the Oracle Graduate Programme: “Responsibility, dedication, focus and taking initiative … these are the key points I learned from Oracle. It is such an honour to finally be part of the Oracle family. The graduate programme itself was a great experience as I managed to learn how Oracle operates – it has been the highlight of my year. I believe that my hard work will assist in the growth of the company.” On the Jordan assignment: “A memory worth embracing. Going to Jordan was a great opportunity as I learned a lot with respect to integration between different cultures and getting to adapt to all things different. I, along with almost every other graduate, discovered that Oracle is far more than a database company. Now I know there is far more to the ‘Big Red’ name.” Emmanuel On the Oracle Graduate Programme: “The programme gave me invaluable exposure to the ICT sector and also provided an opportunity to travel, network and exchange ideas with others. The formal training helped me to improve my presentation skills and gave me a better understanding of business etiquette and communication.” On the assignment to Jordan: “It was my first trip abroad. It was a great chance to get to know each other. I had the opportunity to share ideas, share personal stuff as a team. We met experts who gave us superb training in Oracle Technologies. It was great.”   If you have any questions related to this article feel free to contact  [email protected].  You can find our job opportunities via http://campus.oracle.com.   Technorati Tags: Oracle community,South Africa,Graduate Programme,Jordan,Technologies

  • C#/.NET &ndash; Finding an Item&rsquo;s Index in IEnumerable&lt;T&gt;

    - by James Michael Hare
    Sorry for the long blogging hiatus.  First it was, of course, the holidays hustle and bustle, then my brother and his wife gave birth to their son, so I’ve been away from my blogging for two weeks. Background: Finding an item’s index in List<T> is easy… Many times in our day to day programming activities, we want to find the index of an item in a collection.  Now, if we have a List<T> and we’re looking for the item itself this is trivial: 1: // assume have a list of ints: 2: var list = new List<int> { 1, 13, 42, 64, 121, 77, 5, 99, 132 }; 3:  4: // can find the exact item using IndexOf() 5: var pos = list.IndexOf(64); This will return the position of the item if it’s found, or –1 if not.  It’s easy to see how this works for primitive types where equality is well defined.  For complex types, however, it will attempt to compare them using EqualityComparer<T>.Default which, in a nutshell, relies on the object’s Equals() method. So what if we want to search for a condition instead of equality?  That’s also easy in a List<T> with the FindIndex() method: 1: // assume have a list of ints: 2: var list = new List<int> { 1, 13, 42, 64, 121, 77, 5, 99, 132 }; 3:  4: // finds index of first even number or -1 if not found. 5: var pos = list.FindIndex(i => i % 2 == 0);   Problem: Finding an item’s index in IEnumerable<T> is not so easy... This is all well and good for lists, but what if we want to do the same thing for IEnumerable<T>?  A collection of IEnumerable<T> has no indexing, so there’s no direct method to find an item’s index.  LINQ, as powerful as it is, gives us many tools to get us this information, but not in one step.  As with almost any problem involving collections, there are several ways to accomplish the same goal.  And once again as with almost any problem involving collections, the choice of the solution somewhat depends on the situation. So let’s look at a few possible alternatives.  I’m going to express each of these as extension methods for simplicity and consistency. Solution: The TakeWhile() and Count() combo One of the things you can do is to perform a TakeWhile() on the list as long as your find condition is not true, and then do a Count() of the items it took.  The only downside to this method is that if the item is not in the list, the index will be the full Count() of items, and not –1.  So if you don’t know the size of the list beforehand, this can be confusing. 1: // a collection of extra extension methods off IEnumerable<T> 2: public static class EnumerableExtensions 3: { 4: // Finds an item in the collection, similar to List<T>.FindIndex() 5: public static int FindIndex<T>(this IEnumerable<T> list, Predicate<T> finder) 6: { 7: // note if item not found, result is length and not -1! 8: return list.TakeWhile(i => !finder(i)).Count(); 9: } 10: } Personally, I don’t like switching the paradigm of not found away from –1, so this is one of my least favorites.  Solution: Select with index Many people don’t realize that there is an alternative form of the LINQ Select() method that will provide you an index of the item being selected: 1: list.Select( (item,index) => do something here with the item and/or index... ) This can come in handy, but must be treated with care.  This is because the index provided is only as pertains to the result of previous operations (if any).  For example: 1: // assume have a list of ints: 2: var list = new List<int> { 1, 13, 42, 64, 121, 77, 5, 99, 132 }; 3:  4: // you'd hope this would give you the indexes of the even numbers 5: // which would be 2, 3, 8, but in reality it gives you 0, 1, 2 6: list.Where(item => item % 2 == 0).Select((item,index) => index); The reason the example gives you the collection { 0, 1, 2 } is because the where clause passes over any items that are odd, and therefore only the even items are given to the select and only they are given indexes. Conversely, we can’t select the index and then test the item in a Where() clause, because then the Where() clause would be operating on the index and not the item! So, what we have to do is to select the item and index and put them together in an anonymous type.  It looks ugly, but it works: 1: // extensions defined on IEnumerable<T> 2: public static class EnumerableExtensions 3: { 4: // finds an item in a collection, similar to List<T>.FindIndex() 5: public static int FindIndex<T>(this IEnumerable<T> list, Predicate<T> finder) 6: { 7: // if you don't name the anonymous properties they are the variable names 8: return list.Select((item, index) => new { item, index }) 9: .Where(p => finder(p.item)) 10: .Select(p => p.index + 1) 11: .FirstOrDefault() - 1; 12: } 13: }     So let’s look at this, because i know it’s convoluted: First Select() joins the items and their indexes into an anonymous type. Where() filters that list to only the ones matching the predicate. Second Select() picks the index of the matches and adds 1 – this is to distinguish between not found and first item. FirstOrDefault() returns the first item found from the previous clauses or default (zero) if not found. Subtract one so that not found (zero) will be –1, and first item (one) will be zero. The bad thing is, this is ugly as hell and creates anonymous objects for each item tested until it finds the match.  This concerns me a bit but we’ll defer judgment until compare the relative performances below. Solution: Convert ToList() and use FindIndex() This solution is easy enough.  We know any IEnumerable<T> can be converted to List<T> using the LINQ extension method ToList(), so we can easily convert the collection to a list and then just use the FindIndex() method baked into List<T>. 1: // a collection of extension methods for IEnumerable<T> 2: public static class EnumerableExtensions 3: { 4: // find the index of an item in the collection similar to List<T>.FindIndex() 5: public static int FindIndex<T>(this IEnumerable<T> list, Predicate<T> finder) 6: { 7: return list.ToList().FindIndex(finder); 8: } 9: } This solution is simplicity itself!  It is very concise and elegant and you need not worry about anyone misinterpreting what it’s trying to do (as opposed to the more convoluted LINQ methods above). But the main thing I’m concerned about here is the performance hit to allocate the List<T> in the ToList() call, but once again we’ll explore that in a second. Solution: Roll your own FindIndex() for IEnumerable<T> Of course, you can always roll your own FindIndex() method for IEnumerable<T>.  It would be a very simple for loop which scans for the item and counts as it goes.  There’s many ways to do this, but one such way might look like: 1: // extension methods for IEnumerable<T> 2: public static class EnumerableExtensions 3: { 4: // Finds an item matching a predicate in the enumeration, much like List<T>.FindIndex() 5: public static int FindIndex<T>(this IEnumerable<T> list, Predicate<T> finder) 6: { 7: int index = 0; 8: foreach (var item in list) 9: { 10: if (finder(item)) 11: { 12: return index; 13: } 14:  15: index++; 16: } 17:  18: return -1; 19: } 20: } Well, it’s not quite simplicity, and those less familiar with LINQ may prefer it since it doesn’t include all of the lambdas and behind the scenes iterators that come with deferred execution.  But does having this long, blown out method really gain us much in performance? Comparison of Proposed Solutions So we’ve now seen four solutions, let’s analyze their collective performance.  I took each of the four methods described above and run them over 100,000 iterations of lists of size 10, 100, 1000, and 10000 and here’s the performance results.  Then I looked for targets at the begining of the list (best case), middle of the list (the average case) and not in the list (worst case as must scan all of the list). Each of the times below is the average time in milliseconds for one execution as computer over the 100,000 iterations: Searches Matching First Item (Best Case)   10 100 1000 10000 TakeWhile 0.0003 0.0003 0.0003 0.0003 Select 0.0005 0.0005 0.0005 0.0005 ToList 0.0002 0.0003 0.0013 0.0121 Manual 0.0001 0.0001 0.0001 0.0001   Searches Matching Middle Item (Average Case)   10 100 1000 10000 TakeWhile 0.0004 0.0020 0.0191 0.1889 Select 0.0008 0.0042 0.0387 0.3802 ToList 0.0002 0.0007 0.0057 0.0562 Manual 0.0002 0.0013 0.0129 0.1255   Searches Where Not Found (Worst Case)   10 100 1000 10000 TakeWhile 0.0006 0.0039 0.0381 0.3770 Select 0.0012 0.0081 0.0758 0.7583 ToList 0.0002 0.0012 0.0100 0.0996 Manual 0.0003 0.0026 0.0253 0.2514   Notice something interesting here, you’d think the “roll your own” loop would be the most efficient, but it only wins when the item is first (or very close to it) regardless of list size.  In almost all other cases though and in particular the average case and worst case, the ToList()/FindIndex() combo wins for performance, even though it is creating some temporary memory to hold the List<T>.  If you examine the algorithm, the reason why is most likely because once it’s in a ToList() form, internally FindIndex() scans the internal array which is much more efficient to iterate over.  Thus, it takes a one time performance hit (not including any GC impact) to create the List<T> but after that the performance is much better. Summary If you’re concerned about too many throw-away objects, you can always roll your own FindIndex() method, but for sheer simplicity and overall performance, using the ToList()/FindIndex() combo performs best on nearly all list sizes in the average and worst cases.    Technorati Tags: C#,.NET,Litte Wonders,BlackRabbitCoder,Software,LINQ,List

  • Podcast Show Notes: Collaborate 10 Wrap-Up - Part 1

    - by Bob Rhubart
    OK, I know last week I promised you a program featuring Oracle ACE Directors Mike van Alst (IT-Eye) and Jordan Braunstein (TUSC) and The Definitive Guide to SOA: Oracle Service Bus author Jeff Davies. But things happen. In this case, what happened was Collaborate 10 in Las Vegas. Prior to the event I asked Oracle ACE Director and OAUG board member Floyd Teter to see if he could round up a couple of people at the event for an impromtu interview over Skype (I was here in Cleveland) to get their impressions of the event. Listen to Part 1 Floyd, armed with his brand new iPad, went above and beyond the call of duty. At the appointed hour, which turned out to be about hour after the close of Collaborate 10,  Floyd had gathered nine other people to join him in a meeting room somewhere in the Mandalay Bay Convention Center. Here’s the entire roster: Floyd Teter - Project Manager at Jet Propulsion Lab, OAUG Board Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Mark Rittman - EMEA Technical Director and Co-Founder, Rittman Mead,  ODTUG Board Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Chet Justice - OBI Consultant at BI Wizards Blog | Twitter | LinkedIn | Oracle Mix | Oracle ACE Profile Elke Phelps - Oracle Applications DBA at Humana, OAUG SIG Chair Blog | LinkedIn | Oracle Mix | Book | Oracle ACE Profile Paul Jackson - Oracle Applications DBA at Humana Blog | LinkedIn | Oracle Mix | Book Srini Chavali - Enterprise Database & Tools Leader at Cummins, Inc Blog | LinkedIn | Oracle Mix Dave Ferguson – President, Oracle Applications Users Group LinkedIn | OAUG Profile John King - Owner, King Training Resources Website | LinkedIn | Oracle Mix Gavyn Whyte - Project Portfolio Manager at iFactory Consulting Blog | Twitter | LinkedIn | Oracle Mix John Nicholson - Channels & Alliances at Greenlight Technologies Website | LinkedIn Big thanks to Floyd for assembling the panelists and handling the on-scene MC/hosting duties.  Listen to Part 1 On a technical note, this discussion was conducted over Skype, using Floyd’s iPad, placed in the middle of the table.  During the call the audio was fantastic – the iPad did a remarkable job. Sadly, the Technology Gods were not smiling on me that day. The audio set-up that I tested successfully before the call failed to deliver when we first connected – I could hear the folks in Vegas, but they couldn’t hear me. A frantic, last-minute adjustment appeared to have fixed that problem, and the audio in my headphones from both sides of the conversation was loud and clear.  It wasn’t until I listened to the playback that I realized that something was wrong. So the audio for Vegas side of the discussion has about the same fidelity as a cell phone. It’s listenable, but disappointing when compared to what it sounded like during the discussion. Still, this was a one shot deal, and the roster of panelists and the resulting conversation was too good and too much fun to scrap just because of an unfortunate technical glitch.   Part 2 of this Collaborate 10 Wrap-Up will run next week. After that, it’s back on track with the previously scheduled program.
