• The Evolution Of C#

  - by Paulo Morgado

  The first release of C# (C# 1.0) was all about building a new language for managed code that appealed, mostly, to C++ and Java programmers. The second release (C# 2.0) was mostly about adding what wasn’t time to built into the 1.0 release. The main feature for this release was Generics. The third release (C# 3.0) was all about reducing the impedance mismatch between general purpose programming languages and databases. To achieve this goal, several functional programming features were added to the language and LINQ was born. Going forward, new trends are showing up in the industry and modern programming languages need to be more: Declarative With imperative languages, although having the eye on the what, programs need to focus on the how. This leads to over specification of the solution to the problem in hand, making next to impossible to the execution engine to be smart about the execution of the program and optimize it to run it more efficiently (given the hardware available, for example). Declarative languages, on the other hand, focus only on the what and leave the how to the execution engine. LINQ made C# more declarative by using higher level constructs like orderby and group by that give the execution engine a much better chance of optimizing the execution (by parallelizing it, for example). Concurrent Concurrency is hard and needs to be thought about and it’s very hard to shoehorn it into a programming language. Parallel.For (from the parallel extensions) looks like a parallel for because enough expressiveness has been built into C# 3.0 to allow this without having to commit to specific language syntax. Dynamic There was been lots of debate on which ones are the better programming languages: static or dynamic. The fact is that both have good qualities and users of both types of languages want to have it all. All these trends require a paradigm switch. C# is, in many ways, already a multi-paradigm language. It’s still very object oriented (class oriented as some might say) but it can be argued that C# 3.0 has become a functional programming language because it has all the cornerstones of what a functional programming language needs. Moving forward, will have even more. Besides the influence of these trends, there was a decision of co-evolution of the C# and Visual Basic programming languages. Since its inception, there was been some effort to position C# and Visual Basic against each other and to try to explain what should be done with each language or what kind of programmers use one or the other. Each language should be chosen based on the past experience and familiarity of the developer/team/project/company and not by particular features. In the past, every time a feature was added to one language, the users of the other wanted that feature too. Going forward, when a feature is added to one language, the other will work hard to add the same feature. This doesn’t mean that XML literals will be added to C# (because almost the same can be achieved with LINQ To XML), but Visual Basic will have auto-implemented properties. Most of these features require or are built on top of features of the .NET Framework and, the focus for C# 4.0 was on dynamic programming. Not just dynamic types but being able to talk with anything that isn’t a .NET class. Also introduced in C# 4.0 is co-variance and contra-variance for generic interfaces and delegates. Stay tuned for more on the new C# 4.0 features.

• From NaN to Infinity...and Beyond!

  - by Tony Davis

  It is hard to believe that it was once possible to corrupt a SQL Server Database by storing perfectly normal data values into a table; but it is true. In SQL Server 2000 and before, one could inadvertently load invalid data values into certain data types via RPC calls or bulk insert methods rather than DML. In the particular case of the FLOAT data type, this meant that common 'special values' for this type, namely NaN (not-a-number) and +/- infinity, could be quite happily plugged into the database from an application and stored as 'out-of-range' values. This was like a time-bomb. When one then tried to query this data; the values were unsupported and so data pages containing them were flagged as being corrupt. Any query that needed to read a column containing the special value could fail or return unpredictable results. Microsoft even had to issue a hotfix to deal with failures in the automatic recovery process, caused by the presence of these NaN values, which rendered the whole database inaccessible! This problem is history for those of us on more current versions of SQL Server, but its ghost still haunts us. Recently, for example, a developer on Red Gate’s SQL Response team reported a strange problem when attempting to load historical monitoring data into a SQL Server 2005 database via the C# ADO.NET provider. The ratios used in some of their reporting calculations occasionally threw out NaN or infinity values, and the subsequent attempts to load these values resulted in a nasty error. It turns out to be a different manifestation of the same problem. SQL Server 2005 still does not fully support the IEEE 754 standard for floating point numbers, in that the FLOAT data type still cannot handle NaN or infinity values. Instead, they just added validation checks that prevent the 'invalid' values from being loaded in the first place. For people migrating from SQL Server 2000 databases that contained out-of-range FLOAT (or DATETIME etc.) data, to SQL Server 2005, Microsoft have added to the latter's version of the DBCC CHECKDB (or CHECKTABLE) command a DATA_PURITY clause. When enabled, this will seek out the corrupt data, but won’t fix it. You have to do this yourself in what can often be a slow, painful manual process. Our development team, after a quizzical shrug of the shoulders, simply decided to represent NaN and infinity values as NULL, and move on, accepting the minor inconvenience of not being able to tell them apart. However, what of scientific, engineering and other applications that really would like the luxury of being able to both store and access these perfectly-reasonable floating point data values? The sticking point seems to be the stipulation in the IEEE 754 standard that, when NaN is compared to any other value including itself, the answer is "unequal" (i.e. FALSE). This is clearly different from normal number comparisons and has repercussions for such things as indexing operations. Even so, this hardly applies to infinity values, which are single definite values. In fact, there is some encouraging talk in the Connect note on this issue that they might be supported 'in the SQL Server 2008 timeframe'. If didn't happen; SQL 2008 doesn't support NaN or infinity values, though one could be forgiven for thinking otherwise, based on the MSDN documentation for the FLOAT type, which states that "The behavior of float and real follows the IEEE 754 specification on approximate numeric data types". However, the truth is revealed in the XPath documentation, which states that "…float (53) is not exactly IEEE 754. For example, neither NaN (Not-a-Number) nor infinity is used…". Is it really so hard to fix this problem the right way, and properly support in SQL Server the IEEE 754 standard for the floating point data type, NaNs, infinities and all? Oracle seems to have managed it quite nicely with its BINARY_FLOAT and BINARY_DOUBLE types, so it is technically possible. We have an enterprise-class database that is marketed as being part of an 'integrated' Windows platform. Absurdly, we have .NET and XPath libraries that fully support the standard for floating point numbers, and we can't even properly store these values, let alone query them, in the SQL Server database! Cheers, Tony.

• When to implement: Together with or after the source product?

  - by Jeremy Oosthuizen

  Somebody recently relayed a prospect's question to me: How hard would it be to implement OUBI after the source product (CC&B, WAM or NMS) has already been implemented? Fact is that MOST non-OUBI Data Warehouse / Business Intelligence implementations take place after the source application(s) are in place and hopefully stable. If an organization decides that they need better reporting and management information, then the logical path (see The Data Warehouse Institute's Data Warehouse Maturity Model) is to a Data Warehouse -- no matter when their last applications were implemented. If there is a pre-built Data Warehouse for their specific application, or even for the desired business process in their industry, they're in luck. Else they have to design and build from scratch, using a toolset. The implementation of a toolset is unlike the implementation of OUBI which, like OBI Apps, contain pre-built ETL routines and user content. Much has been written before about the advantages of that. So, because OUBI is designed specifically for Oracle Utilities transactional products, we often implement them in parallel -- with OUBI lagging a little behind by necessity, like Reporting. Customers know from the start they're going to need the solution, and therefore purchase the products at the same time. My biggest argument FOR a parallel installation/implementation of OUBI with the source product is two-fold: - There could be things (which is the technical term for data elements) that customers figure out they need when implementing OUBI, which are often easier added to the source product's implementation project, than to add later; - OUBI's ETL often points out errors (severe or not) with converted data, which are easier to fix during the source product's implementation project, or it may even be impossible to fix afterwards. The Conversion routines sometimes miss these errors, because the source system can live with the not-quite-perfect converted data. If the data can't be properly extracted, i.e. the proper Dimensions linked to the Facts, then it can't get into OUBI. That means it can't be analyzed effectively along with the rest of the organization's data. Then there is also the throw-away-work argument, which may be significant. The operational / transactional system cannot go live without reports on Day 1. A lot of those reports would be taken care of by the implementation of OUBI. If OUBI is implemented after go-live, those reports STILL have to be built during the source product's implementation project, but they become throw-away after the OUBI implementation. I have sometimes been told that it is better to implement OUBI after the source product, because it cuts down on scope and risk for the source product's implementation project. All I can say to that, is bah humbug. No, seriously, given the arguments above, planning has to include the OUBI implementation and it has to be managed properly -- just like any other implementation. If so, it should not add any risk and it should be included in the scope from the start. The answer to the prospect's question is therefore that it is not that much more difficult; after all, most DW/BI implemenations are done like that. They just have to consider the points above.

• Anatomy of a serialization killer

  - by Brian Donahue

  As I had mentioned last month, I have been working on a project to create an easy-to-use managed debugger. It's still an internal tool that we use at Red Gate as part of product support to analyze application errors on customer's computers, and as such, should be easy to use and not require installation. Since the project has got rather large and important, I had decided to use SmartAssembly to protect all of my hard work. This was trivial for the most part, but the loading and saving of results was broken by SA after using the obfuscation, rendering the loading and saving of XML results basically useless, although the merging and error reporting was an absolute godsend and definitely worth the price of admission. (Well, I get my Red Gate licenses for free, but you know what I mean!)My initial reaction was to simply exclude the serializable results class and all of its' members from obfuscation, and that was just dandy, but a few weeks on I decided to look into exactly why serialization had broken and change the code to work with SA so I could write any new code to be compatible with SmartAssembly and save me some additional testing and changes to the SA project.In simple terms, SA does all that it can to prevent serialization problems, for instance, it will not obfuscate public members of a DLL and it will exclude any types with the Serializable attribute from obfuscation. This prevents public members and properties from being made private and having the name changed. If the serialization is done inside the executable, however, public members have the access changed to private and are renamed. That was my first problem, because my types were in the executable assembly and implemented ISerializable, but did not have the Serializable attribute set on them!public class RedFlagResults : ISerializable        {        }The second problem caused by the pruning feature. Although RedFlagResults had public members, they were not truly properties, and used the GetObjectData() method of ISerializable to serialize the members. For that reason, SA could not exclude these members from pruning and further broke the serialization. public class RedFlagResults : ISerializable        {                public List<RedFlag.Exception> Exceptions;                 #region ISerializable Members                 public void GetObjectData(SerializationInfo info, StreamingContext context)                {                                info.AddValue("Exceptions", Exceptions);                }                 #endregionSo to fix this, it was necessary to make Exceptions a proper property by implementing get and set on it. Also, I added the Serializable attribute so that I don't have to exclude the class from obfuscation in the SA project any more. The DoNotPrune attribute means I do not need to exclude the class from pruning.[Serializable, SmartAssembly.Attributes.DoNotPrune]        public class RedFlagResults        {                public List<RedFlag.Exception> Exceptions {get;set;}        }Similarly, the Exception class gets the Serializable and DoNotPrune attributes applied so all of its' properties are excluded from obfuscation.Now my project has some protection from prying eyes by scrambling up the code so it's harder to reverse-engineer, without breaking anything. SmartAssembly has also provided the benefit of merging so that the end-user doesn't need to extract all of the DLL files needed by RedFlag into a directory, and can be run directly from the .zip archive. When an error occurs (hey, I'm only human!), an exception report can be sent to me so I can see what went wrong without having to, er, debug the debugger.

• New Release of Oracle EPM (Enterprise Performance Management)

  - by Theresa Hickman

  I'm a huge fan of Hyperion products and consider Hyperion to be one of the best acquisitions Oracle has made in terms of applications. So I am really excited to talk about their latest release, Release 11.1.2 of the Oracle EPM System. This is EPM's largest release in 2 years, and it's jam-packed with new modules and features. In terms of brand new products, there are three: 1. Public Sector Planning and Budgeting meets the needs of public sector agencies, higher education, governments, etc. that have complex budget requirements. It supports position or employee-based budgeting and integrates with MS Office and your ERP ledgers to perform commitment control. 2. Hyperion Financial Close Management is a complete financial close solution that orchestrates the entire close process from subledgers and general ledger to financial reporting and disclosure submissions. And of course, it is integrated with GL systems and consolidation systems. I saw a demo of this and it looked pretty slick. They have this unified close calendar that looks like a regular calendar that gives each person participating in the close process a task list. It comes with a Gantt chart that shows the relationships and dependencies among closing tasks. There are dashboards to allow you to track the close progress and completion of tasks as well as perform trend analysis and see how much time is being spent on different activities in the close process. This gives you visibility that you never had before to understand where the bottlenecks are and where improvements could be made. I think what I liked best about this product was that it provides a central place for all participants to communicate their progress. When I worked as an Accountant, we used ad hoc tools, such as spreadsheets, Word documents, emails, and phone calls during the close process. I like the idea of having a central system to track the overall progress as well as automate the entire financial close process. Who knows, maybe Accountants won't have to revolve their lives around the month end close anymore with a tool like this. Those periodic fire drills can become predictable, well managed processes. 3. Disclosure Management is an out-of-the-box, pre-packaged XBRL solution to meet statutory reporting requirements. This product is really going to help companies improve the timeliness of producing financial reports. Reports can be authored using MS Word and Excel and then XBRL instance documents can be produced with its embedded XBRL tags. It even supports footnotes and disclosures of non-financial information. With a product like this, companies no longer have to outsource their XBRL filing; they can bring it back in house to save costs and time. In terms of other enhancements, they have ERP Integrator that provides integration and drill downs from Hyperion products to source systems, such as Oracle E-Business Suite, PeopleSoft, and SAP. No other vendor offers this level of integration. There's also a new product that links Oracle Essbase directly to Hyperion Financial Management for internal financial reporting, and new integrations between Hyperion Financial Management and Oracle's GRC products. They also improved the usability of Oracle Hyperion Planning. They made it much easier for end users to use the system via the web or via MS Excel when submitting plans and budgets. It is also integrated with intelligent approval workflows that are data-driven, user-configurable, and scenario-specific to efficiently streamline the budgeting process. Here's the press release from April 7, 2010. Here's the pre-recorded web cast where you can see the demos. Just register and watch the hour long presentation. And finally, here's the newsletter

• GCC 4.2.1 Compiling on Cygwin(Win7 64bit) for iPhone [closed]

  - by Kenneth Noland

  Hey This is going to take a long while to explain, but the short version is that I am currently attempting to compile the LLVM GCC frontend for ARMv7 to compile apps for the Cortex-A8(iPhone 3GS). I'm running into an error from LD when compiling libgcc(part of the gcc compilation process) that has been driving me mad! The command is this: /usr/llvm-gcc-4.2-2.8.source/build/./gcc/xgcc \ -B/usr/llvm-gcc-4.2_2.8.source/build/./gcc \ -B/usr/local/arm-apple-darwin/bin \ -B/usr/local/arm-apple-darwin/lib \ -isystem /usr/local/arm-apple-darwin/include \ -isystem /usr/local/arm-apple-darwin/sys-include \ -O2 -g -W -Wall -Wwrite-strings -wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -fno-inline -dynamiclib -nodefaultlibs -W1,-dead_strip \ -marm \ -install_name /usr/local/arm-apple-darwin/lib/libgcc_s.1.dylib \ -single_module -o ./libgcc_s.1.dylib.tmp \ -W1,-exported_symbols_list,libgcc/./libgcc.map -compatibility_version 1 -current_version 1.0 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc \ ... long list of .o files ... \ -lc And the result is typically a lot of undefined references to malloc, free, exit, etc. which typically indicate that libc is not getting compiled in. After going through the list of errors that ld is throwing, I see at the top that it is attempting to pull in /usr/lib/libc.a and complains that it is not the correct platform. Okay, that makes sense, so I spent 5 minutes on google and found an answer. Turns out that if I copy the libSystem.dylib and rename it to libc.dylib, that should solve the problem, but it doesn't. I couldn't find a copy of that file on my phone, so I pulled it directly from the SDK. I then get this strange error: ld64: in /usr/local/arm-apple-darwin/lib/libc.dylib, can't re-map file, errno=22 At this point, I did everything I could think of. I grabbed a fresh copy of my /usr/lib folder from my iphone and confirmed that libSystem.dylib(and libSystem.B.dylib) wasn't there. I unpacked the raw .ipsw package for iOS 4.2.1 and once again, I could not find a copy of libSystem.dylib there either. I unpacked the iPhoneSDK and MacOS SDK and I managed to find a copy of it in both, but that error just kept persisting. I copied libSystem.dylib, libSystem.B.dylib, tried all sorts of combinations of renaming to libc.dylib and still nothing but errors. I can't find a way to get it to recognize the file and link against it. I also tried linking against the libc.a located in the iphone SDK and that didn't work either. I checked what ./xgcc was firing off, and it was my freshly built copy of arm-apple-darwin-ld64 which should be fine. A little bit of background here. I built LLVM+Clang 2.8 with no errors, and I rebuilt the ODCCTools with some light modifications to get it to compile on Cygwin(I'll post my changes in a patch along with a tutorial if I can get this to work). I also grabbed the iphone-dev "includes" and "csu" project and those completed successfully, although there really is no point to them since I can't get it to link against crt0.a. I'm running out of ideas here. Can anyone help me out on this?

• Exploring packages in code

  In my previous post Searching for tasks with code you can see how to explore the control flow side of packages, drilling down through containers, task, and event handlers, but it didn’t cover the data flow. I recently saw a post on the MSDN forum asking how to edit an existing package programmatically, and the sticking point was how to find the the data flow and the components inside. This post builds on some of the previous code and shows how you can explore all objects inside a package. I took the sample Task Search application I’d written previously, and came up with a totally pointless little console application that just walks through the package and writes out the basic type and name of every object it finds, starting with the package itself e.g. Package – MyPackage . The sample package we used last time showed nested objects as well an event handler; a OnPreExecute event tucked away on the task SQL In FEL. The output of this sample tool would look like this: PackageObjects v1.0.0.0 (1.0.0.26627) Copyright (C) 2009 Konesans Ltd Processing File - Z:\Users\Darren Green\Documents\Visual Studio 2005\Projects\SSISTestProject\EventsAndContainersWithExe cSQLForSearch.dtsx Package - EventsAndContainersWithExecSQLForSearch For Loop - FOR Counter Loop Task - SQL In Counter Loop Sequence Container - SEQ For Each Loop Wrapper For Each Loop - FEL Simple Loop Task - SQL In FEL Task - SQL On Pre Execute for FEL SQL Task Sequence Container - SEQ Top Level Sequence Container - SEQ Nested Lvl 1 Sequence Container - SEQ Nested Lvl 2 Task - SQL In Nested Lvl 2 Task - SQL In Nested Lvl 1 #1 Task - SQL In Nested Lvl 1 #2 Connection Manager – LocalHost The code is very similar to what we had previously, but there are a couple of extra bits to deal with connections and to look more closely at a task and see if it is a Data Flow task. For connections your just examine the package's Connections collection as shown in the abridged snippets below. First you can see the call to the ProcessConnections method, followed by the method itself. // Load the package file Application application = new Application(); using (Package package = application.LoadPackage(filename, null)) { // Write out the package name Console.WriteLine("Package - {0}", package.Name); ... More ... // Look and the connections ProcessConnections(package.Connections); } private static void ProcessConnections(Connections connections) { foreach (ConnectionManager connectionManager in connections) { Console.WriteLine("Connection Manager - {0}", connectionManager.Name); } } What we didn’t see in the sample output above was anything to do with the Data Flow, but rest assured the code now handles it too. The following snippet shows how each task is examined to see if it is a Data Flow task, and if so we can then loop through all of the components inside the data flow. private static void ProcessTaskHost(TaskHost taskHost) { if (taskHost == null) { return; } Console.WriteLine("Task - {0}", taskHost.Name); // Check if the task is a Data Flow task MainPipe pipeline = taskHost.InnerObject as MainPipe; if (pipeline != null) { ProcessPipeline(pipeline); } } private static void ProcessPipeline(MainPipe pipeline) { foreach (IDTSComponentMetaData90 componentMetadata in pipeline.ComponentMetaDataCollection) { Console.WriteLine("Pipeline Component - {0}", componentMetadata.Name); // If you wish to make changes to the component then you should really use the managed wrapper. // CManagedComponentWrapper wrapper = componentMetadata.Instantiate(); // wrapper.SetComponentProperty("PropertyName", "Value"); } } Hopefully you can see how we get a reference to the Data Flow task, and then use the ComponentMetaDataCollection to find out what components we have inside the pipeline. If you wanted to know more about the component you could look at the ObjectType or ComponentClassID properties. After that it gets a bit harder and you should get a reference to the wrapper object as the comment suggest and start using the properties, just like you would in the create packages samples, see our Code Development category for some for these examples.

• Filtering data in LINQ with the help of where clause

  - by vik20000in

   LINQ has bought with itself a super power of querying Objects, Database, XML, SharePoint and nearly any other data structure. The power of LINQ lies in the fact that it is managed code that lets you write SQL type code to fetch data.  Whenever working with data we always need a way to filter out the data based on different condition. In this post we will look at some of the different ways in which we can filter data in LINQ with the help of where clause. Simple Filter for an array. Let’s say we have an array of number and we want to filter out data based on some condition. Below is an example int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 }; var lowNums =                 from num in numbers                 where num < 5                 select num;   Filter based on one of the property in the class. With the help of LINQ we can also filer out data from a list based on value of some property. var soldOutProducts =                 from prod in products                 where prod.UnitsInStock == 0                 select prod; Filter based on Multiple of the property in the class. var expensiveInStockProducts =         from prod in products         where prod.UnitsInStock > 0 && prod.UnitPrice > 3.00M         select prod; Filter based on the index of the Item in the list.In the below example we can see that we are able to filter data based on the index of the item in the list. string[] digits = { "zero", "one", "two", "three", "four", "five", "six"}; var shortDigits = digits.Where((digit, index) => digit.Length < index); There are many other way in which we can filter out data in LINQ. In the above post I have tried and shown few ways using the LINQ. Vikram

• Some thoughts on email hosting for one’s own domain

  - by jamiet

  I have used the same email providers for my own domains for a few years now however I am considering moving over to a new provider. In this email I’ll share my current thoughts and hopefully I’ll get some feedback that might help me to decide on what to do next. What I use today I have three email addresses that I use primarily (I have changed the domains in this blog post as I don’t want to give them away to spammers): [email protected] – My personal account that I give out to family and friends and which I use to register on websites [email protected]  - An account that I use to catch email from the numerous mailing lists that I am on [email protected] – I am a self-employed consultant so this is an account that I hand out to my clients, my accountant, and other work-related organisations Those two domains (jtpersonaldomain.com & jtworkdomain.com) are both managed at http://domains.live.com which is a fantastic service provided by Microsoft that for some perplexing reason they never bother telling anyone about. It offers multiple accounts (I have seven at jtpersonaldomain.com though as already stated I only use two of them) which are accessed via Outlook.com (formerly Hotmail.com) along with usage reporting plus a few other odds and sods that I never use. Best of all though, its totally free. In addition, given that I have got both domains hosted using http://domains.live.com I can link my various accounts together and switch between them at Outlook.com without having to login and logout: N.B. You’ll notice that there are two other accounts listed there in addition to the three I already mentioned. One is my mum’s account which helps me provide IT support/spam filtering services to her and the other is the donation account for AdventureWorks on Azure. I find that linking feature to be very handy indeed. Finally, http://domains.live.com is the epitome of “it just works”. I set up jtworkdomain.com at http://domains.live.com over three years ago and I am pretty certain I haven’t been back there even once to administer it. Proposed changes OK, so if I like http://domains.live.com so much why am I considering changing? Well, I earn my corn in the Microsoft ecosystem and if I’m reading the tea-leaves correctly its looking increasingly likely that the services that I’m going to have to be familiar with in the future are all going to be running on top of and alongside Windows Azure Active Directory and Office 365 respectively. Its clear to me that Microsoft’s are pushing their customers toward cloud services and, like it or lump it, data integration developers like me may have to come along for the ride. I don’t think the day is too far off when we can log into Windows Azure SQL Database (aka SQL Azure), Team Foundation Service, Dynamics etc… using the same credentials that are currently used for Office 365 and over time I would expect those things to get integrated together a lot better – that integration will be based upon a Windows Azure Active Directory identity. This should not come as a surprise, in my opinion Microsoft’s whole enterprise play over the past 15 or 20 years can be neatly surmised as “get people onto Windows Server and Active Directory then upsell from there” – in the not-too-distant-future the only difference is that they’re trying to do it in the cloud. I want to get familiar with these services and hence I am considering moving jtworkdomain.com onto Office 365. I’ll lose the convenience of easily being able to switch to that account at Outlook.com and moreover I’ll have to start paying for it (I think it’ll be about fifty quid a year – not a massive amount but its quite a bit more than free) but increasingly this is beginning to look like a move I have to make. So that’s where my head is at right now. Anyone have any relevant thoughts or experiences to share? Please let me know in the comments below. @Jamiet

• Configuring Multiple Instances of MySQL in Solaris 11

  - by rajeshr

  Recently someone asked me for steps to configure multiple instances of MySQL database in an Operating Platform. Coz of my familiarity with Solaris OE, I prepared some notes on configuring multiple instances of MySQL database on Solaris 11. Maybe it's useful for some: If you want to run Solaris Operating System (or any other OS of your choice) as a virtualized instance in desktop, consider using Virtual Box. To download Solaris Operating System, click here. Once you have your Solaris Operating System (Version 11) up and running and have Internet connectivity to gain access to the Image Packaging System (IPS), please follow the steps as mentioned below to install MySQL and configure multiple instances: 1. Install MySQL Database in Solaris 11 $ sudo pkg install mysql-51 2. Verify if the mysql is installed: $ svcs -a | grep mysql Note: Service FMRI will look similar to the one here: svc:/application/database/mysql:version_51 3. Prepare data file system for MySQL Instance 1 zfs create rpool/mysql zfs create rpool/mysql/data zfs set mountpoint=/mysql/data rpool/mysql/data 4. Prepare data file system for MySQL Instance 2 zfs create rpool/mysql/data2 zfs set mountpoint=/mysql/data rpool/mysql/data2 5. Change the mysql/datadir of the MySQL Service (SMF) to point to /mysql/data $ svcprop mysql:version_51 | grep mysql/data $ svccfg -s mysql:version_51 setprop mysql/data=/mysql/data 6. Create a new instance of MySQL 5.1 (a) Copy the manifest of the default instance to temporary directory: $ sudo cp /lib/svc/manifest/application/database/mysql_51.xml /var/tmp/mysql_51_2.xml (b) Make appropriate modifications on the XML file $ sudo vi /var/tmp/mysql_51_2.xml - Change the "instance name" section to a new value "version_51_2" - Change the value of property name "data" to point to the ZFS file system "/mysql/data2" 7. Import the manifest to the SMF repository: $ sudo svccfg import /var/tmp/mysql_51_2.xml 8. Before starting the service, copy the file /etc/mysql/my.cnf to the data directories /mysql/data & /mysql/data2. $ sudo cp /etc/mysql/my.cnf /mysql/data/ $ sudo cp /etc/mysql/my.cnf /mysql/data2/ 9. Make modifications to the my.cnf in each of the data directories as required: $ sudo vi /mysql/data/my.cnf Under the [client] section port=3306 socket=/tmp/mysql.sock ---- ---- Under the [mysqld] section port=3306 socket=/tmp/mysql.sock datadir=/mysql/data ----- ----- server-id=1 $ sudo vi /mysql/data2/my.cnf Under the [client] section port=3307 socket=/tmp/mysql2.sock ----- ----- Under the [mysqld] section port=3307 socket=/tmp/mysql2.sock datadir=/mysql/data2 ----- ----- server-id=2 10. Make appropriate modification to the startup script of MySQL (managed by SMF) to point to the appropriate my.cnf for each instance: $ sudo vi /lib/svc/method/mysql_51 Note: Search for all occurences of mysqld_safe command and modify it to include the --defaults-file option. An example entry would look as follows: ${MySQLBIN}/mysqld_safe --defaults-file=${MYSQLDATA}/my.cnf --user=mysql --datadir=${MYSQLDATA} --pid=file=${PIDFILE} 11. Start the service: $ sudo svcadm enable mysql:version_51_2 $ sudo svcadm enable mysql:version_51 12. Verify that the two services are running by using: $ svcs mysql 13. Verify the processes: $ ps -ef | grep mysqld 14. Connect to each mysqld instance and verify: $ mysql --defaults-file=/mysql/data/my.cnf -u root -p $ mysql --defaults-file=/mysql/data2/my.cnf -u root -p Some references for Solaris 11 newbies Taking your first steps with Solaris 11 Introducing the basics of Image Packaging System Service Management Facility How To Guide For a detailed list of official educational modules available on Solaris 11, please visit here For MySQL courses from Oracle University access this page.

• Error:couldn't read file-Kernel panic

  - by Thanos

  I have just installed ubuntu 12.04.1. To be honest I had to run installation several times until it was finished fine. When I finally managed to install it properly, I power on the laptop and the grub shoed up! I selected ubuntu generic. It takes some time to load and when it does I get an error message stating that error: couldn't read file Press any key to continue If I press any button nothing happens. If a leave it there, in a short while there is a black screen loading which gives some weird messages [0.946710] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0) [0.946755] Pid: 1, comm: swapper/0 Not tainted 3.2.0-29-generic #46-Ubuntu [0.946792] Call Trace: [0.946831] [<ffffffff81640ec8>] panic+0x91/0x1a4 [0.946869] [<ffffffff81cfc01e>] mount_block_root+0xdc/0x18e [0.946909] [<ffffffff81002930>] ? populate_rootfs_wait+0x300/0x9d0 [0.946947] [<ffffffff81cfc257>] mount_root+0x54/0x59 [0.946982] [<ffffffff81cfcec9>] prepare_namespace+0x16d/0x1a6 [0.947019] [<ffffffff81cfbd63>] kernel_init+0x153/0x158 [0.947094] [<ffffffff81cfbc10>] ? start_kernel+0x3bd/0x3bd [0.947129] [<ffffffff81664030>] ? gs_change+0x13/0x13 The thing is that the laptop isn't mine. A friend tried to dual boot ubuntu alongside windows 7 but he didn't succeed. Ubuntu option was in grub, but when you tried to boot it rebooted from the start. So from a Live CD I erased ubuntu, started windows to check if something went wrong, and fortunately everything was OK. Windows started normally! So I tried to install ubuntu. Before installation was completed the installer crashed! I was afraid that he would lost windows, something that was true... At that point I tried to install windows but whichever distro(XP, 7{home, proffessional, ultimate},8) I tried it could never reach the end. So I tried to reinstall ubuntu but I was facing those weird messages. What can I do to move on? ______________________________________________________________________ EDIT1: I tried to check and fix(if possible) with GParted it took a lot of hours,although gparted displays only 01:14, I restarted the system and now I get not exactly the same messages. Numbers in braces [ ] are different [0.818189] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0) [0.818235] Pid: 1, comm: swapper/0 Not tainted 3.2.0-29-generic #46-Ubuntu [0.818272] Call Trace: [0.818312] [<ffffffff81640ec8>] panic+0x91/0x1a4 [0.818351] [<ffffffff81cfc01e>] mount_block_root+0xdc/0x18e [0.818391] [<ffffffff81002930>] ? populate_rootfs_wait+0x300/0x9d0 [0.818428] [<ffffffff81cfc257>] mount_root+0x54/0x59 [0.818464] [<ffffffff81cfcec9>] prepare_namespace+0x16d/0x1a6 [0.818501] [<ffffffff81cfbd63>] kernel_init+0x153/0x158 [0.818574] [<ffffffff81cfbc10>] ? start_kernel+0x3bd/0x3bd [0.818610] [<ffffffff81664030>] ? gs_change+0x13/0x13 What on earth is going on? ______________________________________________________________________ EDIT2: I forgot to mention that my friend gave a punch to his laptop during a game. After that his cooler became to make a weird noise so I checked and it is a bit tortuous but it is working. What I beleive must be wrong is that his HDD makes a weird noise while trying to load ubuntu, which means he might need a new HDD. Could that be true?

• Laptop screen blank after login when external monitor is not connected

  - by Ramon Suarez

  Ubuntu does not switch back automatically to only monitor present when booting after disconnecting external monitor. Here's a video showing what happens. I get to the login window and everything looks ok, then I type my password, the desktop image shows up and... everything goes blank. It does not happen when I just login as a guest. When possible I work with my laptop connected to an external screen via the VGA port. The problem comes when I boot the computer without that secondary screen connected: The login screen comes out ok. After login the screen goes black, but I can hear the login sound. If I hit ctr + alt + backwards-delete and login again sometimes it is fixed, but not all. If I log in as a different user everything is OK. Then I log in as my user and sometimes it works. To have a screen I have to plug a monitor. Although I have turned on the laptop display with that monitor on, if I reboot it goes blank again after login, even if I turn off the external monitor before turning off the computer. I've managed to get my screen back with my username after going into recovery mode, but only sometimes. Failsafe would not load after second screen asking me what I wanted to do (no mouse to click nor keyboard working). My computer is a LDLC Aurore BB1-i5 -8 -S1. Which is the configuration file that keeps the information about the monitors using Displays under lightgdm and where is it? I guess if I could edit it I may have a chance :) One of the things I tried following a solution in another post was removing my monitors.xml file, but it does not work and I don't know how to create a good one that I could use now. When doing DISPLAY=:0 xrandrI get: Screen 0: minimum 320 x 200, current 320 x 200, maximum 8192 x 8192 LVDS1 connected (normal left inverted right x axis y axis) 1366x768 60.0 + 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) This is the full dmesg after activating sudo xdiagnoseas Bryce sugested. (If you tell me the relevant parts I will paste them here) When conecting the external monitor, only the external will work, although I can see using Displays that the computer thinks that both are working. I've asked the question in Launchpad but have it keeps on expiring without any feedback. In my opinion Ubuntu should be able to detect automatically that there is no external monitor present and switch to the laptop monitor. There's a similar question here, but it does not apply to my case External monitor set as primary even when disconnected from laptop Update: For clarification, the problem happens only with my user and once I log in. I even get to see the screensaver for about a second, and then it goes blank. Tried Bryce's example (see his answer below), but it did not work. This is the info I get from tty1 with Display=:0 xrandr: – Ramon Suarez Jul 9 at 16:36 Screen 0: minimum 320 x 200, current 320 x 200, maximum 8192 x 8192 LVDS1 connected (normal left inverted right x axis y axis) 1366x768 60.0 + 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis)

• Learning content for MCSDs: Web Applications and Windows Store Apps using HTML5

  Recently, I started again to learn for various Microsoft certifications. First candidate on my way to MSCD: Web Applications is the Exam 70-480: Programming in HTML5 with JavaScript and CSS3. Motivation to go for a Microsoft exam I guess, this is quite personal but let me briefly describe my intentions to go that exam. First, I'm doing web development since the 1990's. Working with HTML, CSS and Javascript is happening almost daily in my workspace. And honestly, I do not only do 'pure' web development but already integrated several HTML/CSS/Javascript frontend UIs into an existing desktop application (written in Visual FoxPro) inclusive two-way communication and data exchange. Hm, might be an interesting topic for another blog article here... Second, this exam has a very interesting aspect which is listed at the bottom of the exam's details: Credit Toward Certification When you pass Exam 70-480: Programming in HTML5 with JavaScript and CSS3, you complete the requirements for the following certification(s): Programming in HTML5 with JavaScript and CSS3 Specialist Exam 70-480: Programming in HTML5 with JavaScript and CSS3: counts as credit toward the following certification(s): MCSD: Web Applications MCSD: Windows Store Apps using HTML5 So, passing one single exam will earn you specialist certification straight-forward, and opens the path to higher levels of certifications. Preparations and learning path Well, due to a newsletter from Microsoft Learning (MSL) I caught interest in picking up the circumstances and learning materials for this particular exam. As of writing this article there is a promotional / voucher code available which enables you to register for this exam for free! Simply register yourself with or log into your existing account at Prometric, choose the exam for a testing facility near to you and enter the voucher code HTMLJMP (available through 31.03.2013 or while supplies last). Hurry up, there are restrictions... As stated above, I'm already very familiar with web development and the programming flavours involved into this. But of course, it is always good to freshen up your knowledge and reflect on yourself. Microsoft is putting a lot of effort to attract any kind of developers into the 'App Development'. Whether it is for the Windows 8 Store or the Windows Phone 8 Store, doesn't really matter. They simply need more apps. This demand for skilled developers also comes with a nice side-effect: Lots and lots of material to study. During the first couple of hours, I could easily gather high quality preparation material - again for free! Following is just a small list of starting points. If you have more resources, please drop me a message in the comment section, and I'll be glad to update this article accordingly. Developing HTML5 Apps Jump Start This is an accelerated jump start video course on development of HTML5 Apps for Windows 8. There are six modules that are split into two video sessions per module. Very informative and intense course material. This is packed stuff taken from an official preparation course for exam 70-480. Developing Windows Store Apps with HTML5 Jump Start Again, an accelerated preparation video course on Windows 8 Apps. There are six modules with two video sessions each which will catapult you to your exam. This is also related to preps for exam 70-481. Programming Windows 8 Apps with HTML, CSS, and JavaScript Kraig Brockschmidt delves into the ups and downs of Windows 8 App development over 800+ pages. Great eBook to read, study, and to practice the samples - best of all, it's for free. codeSHOW() This is a Windows 8 HTML/JS project with the express goal of demonstrating simple development concepts for the Windows 8 platform. Code, code and more code... absolutely great stuff to study and practice. Microsoft Virtual Academy I already wrote about the MVA in a previous article. Well, if you haven't registered yourself yet, now is the time. The list is not complete for sure, but this might keep you busy for at least one or even two weeks to go through the material. Please don't hesitate to add more resources in the comment section. Right now, I'm already through all videos once, and digging my way through chapter 4 of Kraig's book. Additional material - Pluralsight Apart from those free online resources, I also following some courses from the excellent library of Pluralsight. They already have their own section for Windows 8 development, but of course, you get companion material about HTML5, CSS and Javascript in other sections, too. Introduction to Building Windows 8 Applications Building Windows 8 Applications with JavaScript and HTML Selling Windows 8 Apps HTML5 Fundamentals Using HTML5 and CSS3 HTML5 Advanced Topics CSS3 etc... Interesting to see that Michael Palermo provides his course material on multiple platforms. Fantastic! You might also pay a visit to his personal blog. Hm, it just came to my mind that Aaron Skonnard of Pluralsight publishes so-called '24 hours Learning Paths' based on courses available in the course library. Would be interested to see a combination for Windows 8 App development using HTML5, CSS3 and Javascript in the future. Recommended workspace environment Well, you might have guessed it but this requires Windows 8, Visual Studio 2012 Express or another flavour, and a valid Developers License. Due to an MSDN subscription I working on VS 2012 Premium with some additional tools by Telerik. Honestly, the fastest way to get you up and running for Windows 8 App development is the source code archive of codeSHOW(). It does not only give you all source code in general but contains a couple of SDKs like Bing Maps, Microsoft Advertising, Live ID, and Telerik Windows 8 controls... for free! Hint: Get the Windows Phone 8 SDK as well. Don't worry, while you are studying the material for Windows 8 you will be able to leverage from this knowledge to development for the phone platform, too. It takes roughly one to two hours to get your workspace and learning environment, at least this was my time frame due to slow internet connection and an aged spare machine. ;-) Oh, before I forget to mention it, as soon as you're done, go quickly to the Windows Store and search for ClassBrowserPlus. You might not need it ad hoc for your development using HTML5, CSS and Javascript but I think that it is a great developer's utility that enables you to view the properties, methods and events (along with help text) for all Windows 8 classes. It's always good to look behind the scenes and to explore how it is made. Idea: Start/join a learning group The way you learn new things or intensify your knowledge in a certain technology is completely up to your personal preference. Back in my days at the university, we used to meet once or twice a week in a small quiet room to exchange our progress, questions and problems we ran into. In general, I recommend to any software craftsman to lift your butt and get out to exchange with other developers. Personally, I like this approach, as it gives you new points of view and an insight into others' own experience with certain techniques and how they managed to solve tricky issues. Just keep it relaxed and not too formal after all, and you might a have a good time away from your dull office desk. Give your machine a break, too.

• Database – Beginning with Cloud Database As A Service

  - by Pinal Dave

  I love my weekend projects. Everybody does different activities in their weekend – like traveling, reading or just nothing. Every weekend I try to do something creative and different in the database world. The goal is I learn something new and if I enjoy my learning experience I share with the world. This weekend, I decided to explore Cloud Database As A Service – Morpheus. In my career I have managed many databases in the cloud and I have good experience in managing them. I should highlight that today’s applications use multiple databases from SQL for transactions and analytics, NoSQL for documents, In-Memory for caching to Indexing for search.  Provisioning and deploying these databases often require extensive expertise and time.  Often these databases are also not deployed on the same infrastructure and can create unnecessary latency between the application layer and the databases.  Not to mention the different quality of service based on the infrastructure and the service provider where they are deployed. Moreover, there are additional problems that I have experienced with traditional database setup when hosted in the cloud: Database provisioning & orchestration Slow speed due to hardware issues Poor Monitoring Tools High network latency Now if you have a great software and expert network engineer, you can continuously work on above problems and overcome them. However, not every organization have the luxury to have top notch experts in the field. Now above issues are related to infrastructure, but there are a few more problems which are related to software/application as well. Here are the top three things which can be problems if you do not have application expert: Replication and Clustering Simple provisioning of the hard drive space Automatic Sharding Well, Morpheus looks like a product build by experts who have faced similar situation in the past. The product pretty much addresses all the pain points of developers and database administrators. What is different about Morpheus is that it offers a variety of databases from MySQL, MongoDB, ElasticSearch to Reddis as a service.  Thus users can pick and chose any combination of these databases.  All of them can be provisioned in a matter of minutes with a simple and intuitive point and click user interface.  The Morpheus cloud is built on Solid State Drives (SSD) and is designed for high-speed database transactions.  In addition it offers a direct link to Amazon Web Services to minimize latency between the application layer and the databases. Here are the few steps on how one can get started with Morpheus. Follow along with me.  First go to http://www.gomorpheus.com and register for a new and free account. Step 1: Signup It is very simple to signup for Morpheus. Step 2: Select your database   I use MySQL for my daily routine, so I have selected MySQL. Upon clicking on the big red button to add Instance, it prompted a dialogue of creating a new instance.   Step 3: Create User Now we just have to create a user in our portal which we will use to connect to a database hosted at Morpheus. Click on your database instance and it will bring you to User Screen. Over here you will notice once again a big red button to create a new user. I created a user with my first name.   Step 4: Configure your MySQL client I used MySQL workbench and connected to MySQL instance, which I had created with an IP address and user.   That’s it! You are connecting to MySQL instance. Now you can create your objects just like you would create on your local box. You will have all the features of the Morpheus when you are working with your database. Dashboard While working with Morpheus, I was most impressed with its dashboard. In future blog posts, I will write more about this feature.  Also with Morpheus you use the same process for provisioning and connecting with other databases: MongoDB, ElasticSearch and Reddis.

• Personal Development : Time, Planning , Repairs & Maintenance

  - by Rajesh Pillai

  Personal Development : Time, Planning, Repairs & Maintenance These are just my thoughts, but some you may find something interesting in it. Please think over it. We may know many things, but still we always keeps procrastinating it. I have written this as I have heard many people coming back and saying they don’t have time to do things they like. These are my thoughts buy may be useful to someone else too. Certain things in life needs periodic repairs and maintenance. To cite some examples , your CAR, your HOUSE, your personal laptop/desktop, your health etc. Likewise there are certain other things in professional life that requires repair/ maintenance /or some kind of polishing, so that you always stay on top of it. But they are not always obvious. Some of them are - Improving your communication skills - Increasing your vocabulary - Upgrading your technical skills - Pursuing your hobby - Increasing your knowledge/awareness etc… etc… And then there are certain things that we are always short of…. one is TIME. We all know TIME is one of the most precious things in life and yet we all are very miserable at managing it. Remember you can only manage it and not control it. You can only control which you own or which you create. In theory time is infinite. So, there should be abundant of it. But remember one thing, you know this, it’s not reversible. Once it has elapsed you cannot live it again. Think over it. So, how do find that golden 25th hour every day. To find the 25th hour you need to reflect back on your current daily activities. Analyze them and see where you are spending most of your time and is it really important. Even the 8 hours that you spent in the office, is it spent fruitfully. At the end of the day is the 8 precious hour that you spent was worth it. Just reflect back on your activities. Did you learn something? If yes did you make a point to NOTE IT. If you didn’t NOTED it then was the time you spent really worth it. Just ponder over it. Some calculations of your daily activities where most of the time is spent. Let’s start (in no particular order though) - Sleep (6.5 hours) [Remember you only require 6 good hours of sleep every day]. Some may thing it is 8, but it’s a myth.   o To achive 6 hours of sleep and be in good health you can practice 15 minutes of daily meditation. So effectively you can    round it to 6.5 hours. - Morning chores(2 hours) : Some may need to prepare breakfast and all other things. - Office commuting (avg. to and fro 3 hours) - Office Work (avg 9.5 hours) Total Hours: 21 hours effective time which is spent irrespective of what you do. There may be some variations here and there. Still you have 3 hours EXTRA. Where do these 3 hours go? If you can find it, then you may get that golden 25th hour out of these 3 hours. Let’s discount 2 hours for contingencies, still you have 1 hour with you. If you can’t find it then you are living a direction less life. As you can see, the 25th Hour lies within the 24 hours of the day. It’s upto each one of us to find and make use of it. Now what can you do with that 25th hour i.e. 1 hour extra of your life. Imagine the possibility. Again some calculations 1 hour daily * 30 days = 30 hours every month 30 hours pm * 12 month = 360 hours every year. 360 hours every year seems very promising. Let’s add some contingencies, say, let’s be optimistic and say 50 % contingency. Still you have 180 hours every year. That leaves with 30 minutes every day of extra time. That’s hell a lot of time, if you could manage it. These may sound like a high talk [yes, it is, unless you apply these simple rules and rationalize your everyday living and stop procrastinating]. NOTE: I haven’t taken weekend, holidays and leaves into account. So, that leaves us with a lot of buffer time. You can meet family friends, relatives, other tasks, and yet have these 180 pure hours of joy every year. Do whatever you want to do with it. So, how important is this 180 hours per year to you? Just think over it. You may use it the way you like - 50 hours [pursue your hobby like drawing, crafting, learn dance, learn juggling, learn swimming, travelling hmm.. anything you like doing and you didn’t had time to do it.] - 30 hours you can learn a new programming language or technology (i.e. you can get comfortable with it) - 50 hours [improve existing skills] - 20 hours [improve you communication skill]. Do some light reading. - 30 hours [YOU DECIDE WHAT TO DO]? So, if you had done this for one year you would have learnt a new programming language, upgraded existing skills, improved you communication etc.. If you had done this for two years.. imagine the level of personal development or growth which you may have attained….. If you had done this for three years….. NOW I think I don’t need to mention this… So, you still have TIME, as they say TIME is infinite. So, make judicious use of this precious thing. And never ever comeback saying “I don’t have time”. So, if you are RICH in TIME, everything else will be automatically taken care of, as those things may just be a byproduct of how you spend your time… So, happy TIMING your TIME everyday.

• Oracle WebCenter: Common User Experience Architecture

  - by kellsey.ruppel(at)oracle.com

  You may remember that the key goals of the new release of WebCenter are providing a Modern User Experience, unparalleled Application Integration, converging all the best of the existing portal platforms into WebCenter and delivering a Common User Experience Architecture.  In previous weeks we've provided an overview of Oracle WebCenter and discussed some of the other key goals and this week, we'll focus on how the new release of Oracle WebCenter delivers a Common User Experience Architecture.When Oracle talks about a Common User Experience Architecture, it really focuses on a core set of areas.  First, the way that information is accessed needs to be consistent and extensible so that as requirements change, the applications don't need to be rewritten for every change. Second, this information access layer needs to be securely accessible to any application, site, or any other channel that needs to leverage this information.  Third, there needs to be a consistent presentation layout, Oracle calls it a UI shell, so that all resources can fit together in a useable, productive way.  Fourth, there needs to be a common set of design patterns for how different menus, features, and services fit into this UI Shell for broad and productive usability.  Fifth, there needs to be a set of design patterns for the individual services that plug into this UI shell so that end users can move from one module of the application to another without new learning.  Finally, all of these layers need to be customizable in an easy way that insulates IT from patching and upgrading problems and allows the business owners the agility to quickly change with the market conditions.As Oracle has already announced, we will release our next generation of enterprise applications called Oracle Fusion Applications.  We have thousands of developers building these applications that all had different programming tool experience and UI design experience.  We've educated over 6,000 developers building Oracle Fusion Applications to leverage these Common User Experience Architecture patterns to speed their learning curve of the new Java standards as well as SOA principles to deliver a revolutionary new set of applications.  You could imagine the big challenge with getting all these developers with different backgrounds and different UI design skills to deliver a completely integrated application user experience.  This is why Oracle invested heavily in designing this Common User Experience Architecture, based on Oracle WebCenter and the Oracle Application Development Framework (ADF).  It pulls together the best practices and design patterns that Oracle development required in order to bring Fusion Applications to market and Oracle WebCenter is the user experience layer that all of this is surfaced through.  In this way, customers can quickly brand a deployment for new partnerships without having to redevelop a new site.  Or they can quickly add new options to the UI Shell to enable their line of business managers to quickly adapt to a new competitive product.  And with the core integration of the activities to produce a Business Activity Stream, customers are able to stay on top of all their key business actions when they happen as they happen and more importantly, the system can recommend actions or resources to help act on these activities.And we've authored this whole set of design patterns for Oracle development to take advantage of in delivering Fusion Applications.  We're also applying these design patterns to our existing eBusiness Suite, Peoplesoft, Siebel, and JD Edwards applications so that they can tie in the exact same way that Fusion Applications has been brought together.  This will provide customers with a complete Common User Experience Architecture for their entire ecosystem of applications within their enterprise whether they are from Oracle, another vender, or custom built applications. And this is all provided in the new release of Oracle WebCenter.  These design patterns cover elements around delivering a complete, aggregated menu of all the capabilities that their role allows independent of which application they are trying to access.   It means that as they move from one application to another, they will have a consistent user experience.  And if they are using an Oracle application, any customizations that are made to the application are preserved and managed through upgrades and patches.Be sure to check back this week as we share more information and resources on Oracle's Common User Experience Architecture.

• Oracle and Partners release CAMP specification for PaaS Management

  - by macoracle

  Cloud Application Management for Platforms The public release of the Cloud Application Management for Platforms (CAMP) specification, an initial draft of what is expected to become an industry standard self service interface specification for Platform as a Service (PaaS) management, represents a significant milestone in cloud standards development. Created by several players in the emerging cloud industry, including Oracle, the specification is being submitted to the OASIS standards organization (draft charter) where it will be finalized in an open development process. CAMP is targeted at application developers and deployers for self service management of their application on a Platform-as-a-Service cloud. It is closely aligned with the application development process where applications are typically developed in an Application Development Environment (ADE) and then deployed into a private or public platform cloud. CAMP standardizes the model behind an application’s dependencies on platform components and provides a standardized format for moving applications between the ADE and the cloud, and if and when desirable, between clouds. Once an application is deployed, CAMP provides users with a standardized self service interface to the PaaS offering, allowing the cloud consumer to manage the lifecycle of the application on that platform and the use of the underlying platform services. The CAMP interface includes a RESTful binding of the CAMP model onto the standard HTTP protocol, using JSON as the encoding for the model resources. The model for CAMP includes resources that represent the Application, its Components and any Platform Components that they depend on. It's important PaaS Cloud consumers understand that for a PaaS cloud, these are the abstractions that the user would prefer to work with, not Virtual Machines and the various resources such as compute power, storage and networking. PaaS cloud consumers would also not like to become system administrators for the infrastructure that is hosting their applications and component services. CAMP works on this more abstract level, and yet still accommodates platforms that are built using an underlying infrastructure cloud. With CAMP, it is up to the cloud provider whether or not this underlying infrastructure is exposed to the consumer. One major challenge addressed by the CAMP specification is that of ensuring that application deployment on a new platform is as seamless and error free as possible. This becomes even more difficult when the application may have been developed for a different platform and is now moving to a new one. In CAMP this is accomplished by matching the requirements of the application and its components to the specific capabilities of the underlying platform. This needs to be done regardless of whether there are existing pools of virtualized platform resources (such as a database pool) which are provisioned(on the basis of a schema for example), or whether the platform component is really just a set of virtual machines drawn from an infrastructure pool. The interoperability between platform clouds that CAMP offers means that a CAMP client such as an ADE can target multiple clouds with a single common interface. Applications can even be spread across multiple platform clouds and then managed without needing to create a specialized adapter to manage the components running in each cloud. The development of CAMP has been an effort by a small set of companies, but there are significant advantages to this approach. For example, the way that each of these companies creates their platforms is different enough, to ensure that CAMP can cover a wide range of actual deployments. CAMP is now entering the next phase of development under the guidance of an open standards organization, OASIS, which will likely broaden it’s capabilities. We hope is to keep it concise and minimal, however, to ease implementation and adoption. Over time there will be many different types of platform components that applications can use and which need management. CAMP at this point only includes one example of this (in an appendix) – DataBase as a Service. I am looking forward to the start of the CAMP Technical Committee in OASIS and will do my best to ensure a successful development process. Hope to see you there.

• A Good Developer is So Hard to Find

  - by James Michael Hare

  Let me start out by saying I want to damn the writers of the Toughest Developer Puzzle Ever – 2. It is eating every last shred of my free time! But as I've been churning through each puzzle and marvelling at the brain teasers and trivia within, I began to think about interviewing developers and why it seems to be so hard to find good ones.  The problem is, it seems like no matter how hard we try to find the perfect way to separate the chaff from the wheat, inevitably someone will get hired who falls far short of expectations or someone will get passed over for missing a piece of trivia or a tricky brain teaser that could have been an excellent team member.   In shops that are primarily software-producing businesses or other heavily IT-oriented businesses (Microsoft, Amazon, etc) there often exists a much tighter bond between HR and the hiring development staff because development is their life-blood. Unfortunately, many of us work in places where IT is viewed as a cost or just a means to an end. In these shops, too often, HR and development staff may work against each other due to differences in opinion as to what a good developer is or what one is worth.  It seems that if you ask two different people what makes a good developer, often you will get three different opinions.   With the exception of those shops that are purely development-centric (you guys have it much easier!), most other shops have management who have very little knowledge about the development process.  Their view can often be that development is simply a skill that one learns and then once aquired, that developer can produce widgets as good as the next like workers on an assembly-line floor.  On the other side, you have many developers that feel that software development is an art unto itself and that the ability to create the most pure design or know the most obscure of keywords or write the shortest-possible obfuscated piece of code is a good coder.  So is it a skill?  An Art?  Or something entirely in between?   Saying that software is merely a skill and one just needs to learn the syntax and tools would be akin to saying anyone who knows English and can use Word can write a 300 page book that is accurate, meaningful, and stays true to the point.  This just isn't so.  It takes more than mere skill to take words and form a sentence, join those sentences into paragraphs, and those paragraphs into a document.  I've interviewed candidates who could answer obscure syntax and keyword questions and once they were hired could not code effectively at all.  So development must be more than a skill.   But on the other end, we have art.  Is development an art?  Is our end result to produce art?  I can marvel at a piece of code -- see it as concise and beautiful -- and yet that code most perform some stated function with accuracy and efficiency and maintainability.  None of these three things have anything to do with art, per se.  Art is beauty for its own sake and is a wonderful thing.  But if you apply that same though to development it just doesn't hold.  I've had developers tell me that all that matters is the end result and how you code it is entirely part of the art and I couldn't disagree more.  Yes, the end result, the accuracy, is the prime criteria to be met.  But if code is not maintainable and efficient, it would be just as useless as a beautiful car that breaks down once a week or that gets 2 miles to the gallon.  Yes, it may work in that it moves you from point A to point B and is pretty as hell, but if it can't be maintained or is not efficient, it's not a good solution.  So development must be something less than art.   In the end, I think I feel like development is a matter of craftsmanship.  We use our tools and we use our skills and set about to construct something that satisfies a purpose and yet is also elegant and efficient.  There is skill involved, and there is an art, but really it boils down to being able to craft code.  Crafting code is far more than writing code.  Anyone can write code if they know the syntax, but so few people can actually craft code that solves a purpose and craft it well.  So this is what I want to find, I want to find code craftsman!  But how?   I used to ask coding-trivia questions a long time ago and many people still fall back on this.  The thought is that if you ask the candidate some piece of coding trivia and they know the answer it must follow that they can craft good code.  For example:   What C++ keyword can be applied to a class/struct field to allow it to be changed even from a const-instance of that class/struct?  (answer: mutable)   So what do we prove if a candidate can answer this?  Only that they know what mutable means.  One would hope that this would infer that they'd know how to use it, and more importantly when and if it should ever be used!  But it rarely does!  The problem with triva questions is that you will either: Approve a really good developer who knows what some obscure keyword is (good) Reject a really good developer who never needed to use that keyword or is too inexperienced to know how to use it (bad) Approve a really bad developer who googled "C++ Interview Questions" and studied like hell but can't craft (very bad) Many HR departments love these kind of tests because they are short and easy to defend if a legal issue arrises on hiring decisions.  After all it's easy to say a person wasn't hired because they scored 30 out of 100 on some trivia test.  But unfortunately, you've eliminated a large part of your potential developer pool and possibly hired a few duds.  There are times I've hired candidates who knew every trivia question I could throw out them and couldn't craft.  And then there are times I've interviewed candidates who failed all my trivia but who I took a chance on who were my best finds ever.    So if not trivia, then what?  Brain teasers?  The thought is, these type of questions measure the thinking power of a candidate.  The problem is, once again, you will either: Approve a good candidate who has never heard the problem and can solve it (good) Reject a good candidate who just happens not to see the "catch" because they're nervous or it may be really obscure (bad) Approve a candidate who has studied enough interview brain teasers (once again, you can google em) to recognize the "catch" or knows the answer already (bad). Once again, you're eliminating good candidates and possibly accepting bad candidates.  In these cases, I think testing someone with brain teasers only tests their ability to answer brain teasers, not the ability to craft code. So how do we measure someone's ability to craft code?  Here's a novel idea: have them code!  Give them a computer and a compiler, or a whiteboard and a pen, or paper and pencil and have them construct a piece of code.  It just makes sense that if we're going to hire someone to code we should actually watch them code.  When they're done, we can judge them on several criteria: Correctness - does the candidate's solution accurately solve the problem proposed? Accuracy - is the candidate's solution reasonably syntactically correct? Efficiency - did the candidate write or use the more efficient data structures or algorithms for the job? Maintainability - was the candidate's code free of obfuscation and clever tricks that diminish readability? Persona - are they eager and willing or aloof and egotistical?  Will they work well within your team? It may sound simple, or it may sound crazy, but when I'm looking to hire a developer, I want to see them actually develop well-crafted code.

• Cloud Computing = Elasticity * Availability

  - by Herve Roggero

  What is cloud computing? Is hosting the same thing as cloud computing? Are you running a cloud if you already use virtual machines? What is the difference between Infrastructure as a Service (IaaS) and a cloud provider? And the list goes on… these questions keep coming up and all try to fundamentally explain what “cloud” means relative to other concepts. At the risk of over simplification, answering these questions becomes simpler once you understand the primary foundations of cloud computing: Elasticity and Availability.   Elasticity The basic value proposition of cloud computing is to pay as you go, and to pay for what you use. This implies that an application can expand and contract on demand, across all its tiers (presentation layer, services, database, security…).  This also implies that application components can grow independently from each other. So if you need more storage for your database, you should be able to grow that tier without affecting, reconfiguring or changing the other tiers. Basically, cloud applications behave like a sponge; when you add water to a sponge, it grows in size; in the application world, the more customers you add, the more it grows. Pure IaaS providers will provide certain benefits, specifically in terms of operating costs, but an IaaS provider will not help you in making your applications elastic; neither will Virtual Machines. The smallest elasticity unit of an IaaS provider and a Virtual Machine environment is a server (physical or virtual). While adding servers in a datacenter helps in achieving scale, it is hardly enough. The application has yet to use this hardware.  If the process of adding computing resources is not transparent to the application, the application is not elastic.   As you can see from the above description, designing for the cloud is not about more servers; it is about designing an application for elasticity regardless of the underlying server farm.   Availability The fact of the matter is that making applications highly available is hard. It requires highly specialized tools and trained staff. On top of it, it's expensive. Many companies are required to run multiple data centers due to high availability requirements. In some organizations, some data centers are simply on standby, waiting to be used in a case of a failover. Other organizations are able to achieve a certain level of success with active/active data centers, in which all available data centers serve incoming user requests. While achieving high availability for services is relatively simple, establishing a highly available database farm is far more complex. In fact it is so complex that many companies establish yearly tests to validate failover procedures.   To a certain degree certain IaaS provides can assist with complex disaster recovery planning and setting up data centers that can achieve successful failover. However the burden is still on the corporation to manage and maintain such an environment, including regular hardware and software upgrades. Cloud computing on the other hand removes most of the disaster recovery requirements by hiding many of the underlying complexities.   Cloud Providers A cloud provider is an infrastructure provider offering additional tools to achieve application elasticity and availability that are not usually available on-premise. For example Microsoft Azure provides a simple configuration screen that makes it possible to run 1 or 100 web sites by clicking a button or two on a screen (simplifying provisioning), and soon SQL Azure will offer Data Federation to allow database sharding (which allows you to scale the database tier seamlessly and automatically). Other cloud providers offer certain features that are not available on-premise as well, such as the Amazon SC3 (Simple Storage Service) which gives you virtually unlimited storage capabilities for simple data stores, which is somewhat equivalent to the Microsoft Azure Table offering (offering a server-independent data storage model). Unlike IaaS providers, cloud providers give you the necessary tools to adopt elasticity as part of your application architecture.    Some cloud providers offer built-in high availability that get you out of the business of configuring clustered solutions, or running multiple data centers. Some cloud providers will give you more control (which puts some of that burden back on the customers' shoulder) and others will tend to make high availability totally transparent. For example, SQL Azure provides high availability automatically which would be very difficult to achieve (and very costly) on premise.   Keep in mind that each cloud provider has its strengths and weaknesses; some are better at achieving transparent scalability and server independence than others.    Not for Everyone Note however that it is up to you to leverage the elasticity capabilities of a cloud provider, as discussed previously; if you build a website that does not need to scale, for which elasticity is not important, then you can use a traditional host provider unless you also need high availability. Leveraging the technologies of cloud providers can be difficult and can become a journey for companies that build their solutions in a scale up fashion. Cloud computing promises to address cost containment and scalability of applications with built-in high availability. If your application does not need to scale or you do not need high availability, then cloud computing may not be for you. In fact, you may pay a premium to run your applications with cloud providers due to the underlying technologies built specifically for scalability and availability requirements. And as such, the cloud is not for everyone.   Consistent Customer Experience, Predictable Cost With all its complexities, buzz and foggy definition, cloud computing boils down to a simple objective: consistent customer experience at a predictable cost.  The objective of a cloud solution is to provide the same user experience to your last customer than the first, while keeping your operating costs directly proportional to the number of customers you have. Making your applications elastic and highly available across all its tiers, with as much automation as possible, achieves the first objective of a consistent customer experience. And the ability to expand and contract the infrastructure footprint of your application dynamically achieves the cost containment objectives.     Herve Roggero is a SQL Azure MVP and co-author of Pro SQL Azure (APress).  He is the co-founder of Blue Syntax Consulting (www.bluesyntax.net), a company focusing on cloud computing technologies helping customers understand and adopt cloud computing technologies.

• Microsoft Cloud Day - the ups and downs

  - by Charles Young

  The term ‘cloud’ can sometimes obscure the obvious.  Today’s Microsoft Cloud Day conference in London provided a good example.  Scott Guthrie was halfway through what was an excellent keynote when he lost network connectivity.  This proved very disruptive to his presentation which centred on a series of demonstrations of the Azure platform in action.  Great efforts were made to find a solution, but no quick fix presented itself.  The venue’s IT facilities were dreadful – no WiFi, poor 3G reception (forget 4G…this is the UK) and, unbelievably, no-one on hand from the venue staff to help with infrastructure issues.  Eventually, after an unscheduled break, a solution was found and Scott managed to complete his demonstrations.  Further connectivity issues occurred during the day. I can say that the cause was prosaic.  A member of the venue staff had interfered with a patch board and inadvertently disconnected Scott Guthrie’s machine from the network by pulling out a cable. I need to state the obvious here.  If your PC is disconnected from the network it can’t communicate with other systems.  This could include a machine under someone’s desk, a mail server located down the hall, a server in the local data centre, an Internet search engine or even, heaven forbid, a role running on Azure. Inadvertently disconnecting a PC from the network does not imply a fundamental problem with the cloud or any specific cloud platform.  Some of the tweeted comments I’ve seen today are analogous to suggesting that, if you accidently unplug your microwave from the mains, this suggests some fundamental flaw with the electricity supply to your house.   This is poor reasoning, to say the least. As far as the conference was concerned, the connectivity issue in the keynote, coupled with some later problems in a couple of presentations, served to exaggerate the perception of poor organisation.   Software problems encountered before the conference prevented the correct set-up of a smartphone app intended to convey agenda information to attendees.  Although some information was available via this app, the organisers decided to print out an agenda at the last moment.  Unfortunately, the agenda sheet did not convey enough information, and attendees were forced to approach conference staff through the day to clarify locations of the various presentations. Despite these problems, the overwhelming feedback from conference attendees was very positive.  There was a real sense of excitement in the morning keynote.  For many, this was their first sight of new Azure features delivered in the ‘spring’ release.  The most common reaction I heard was amazement and appreciation that Azure’s new IaaS features deliver built-in template support for several flavours of Linux from day one.  This coupled with open source SDKs and several presentations on Azure’s support for Java, node.js, PHP, MongoDB and Hadoop served to communicate that the Azure platform is maturing quickly.  The new virtual network capabilities also surprised many attendees, and the much improved portal experience went down very well. So, despite some very irritating and disruptive problems, the event served its purpose well, communicating the breadth and depth of the newly upgraded Azure platform.  I enjoyed the day very much.

• Why Your ERP System Isn't Ready for the Next Evolution of the Enterprise

  - by ken.pulverman

    ERP has been the backbone of enterprise software.  The data held in your ERP system is core of most companies.  Efficiencies gained through the accounting and resource allocation through ERP software have literally saved companies trillions of dollars. Not only does everything seem to be fine with your ERP system, you haven't had to touch it in years.  Why aren't you ready for what comes next? Well judging by the growth rates in the space (Oracle posted only a 3% growth rate, while SAP showed a 12% decline) there hasn't been much modernization going on, just a little replacement activity. If you are like most companies, your ERP system is connected to a proprietary middleware solution that only effectively talks with a handful of other systems you might have acquired from the same vendor.   Connecting your legacy system through proprietary middleware is expensive and brittle and if you are like most companies, you were only willing to pay an SI so much before you said "enough."  So your ERP is working.  It's humming along.  You might not be able to get Order to Promise information when you take orders in your call center, but there are work arounds that work just fine. So what's the problem? The problem is that you built your business around your ERP core, and now there is such pressure to innovate your business processes to keep up that you need a whole new slew of modern apps and you need ERP data to be accessible from everywhere.   Every time you change a sales territory or a comp plan or change a benefits provider your ERP system, literally the economic brain of your business, needs to know what's going on.  And this giant need to access and provide information to your ERP is only growing. What makes matters even more challenging is that apps today come in every flavor under the Sun™.   SaaS, cloud, managed, hybrid, outsourced, composite....and they all have different integration protocols. The only easy way to get ahead of all this is to modernize the way you connect and run your applications.  Unlike the middleware solutions of yesteryear, modern middleware is effectively the operating system of the enterprise.  In the same way that you rely on Apple, Microsoft, and Google to find a video driver for your 23" monitor or to ensure the Word or Keynote runs, modern middleware takes care of intra-application connectivity and process execution.  It effectively allows you to take ERP out of the middle while ensuring connectivity to your vital data for anything you want to do.  The diagram below reflects that change.    In this model, the hegemony of ERP is over.  It too has to become a stealthy modern app to help you quickly adapt to business changes while managing vital information.  And through modern middleware it will connect to everything.  So yes ERP as we've know it is dead, but long live ERP as a connected application member of the modern enterprise. I want to Thank Andrew Zoldan, Group Vice President Oracle Manufacturing Industries Business Unit for introducing me to how some of his biggest customers have benefited by modernizing their applications infrastructure and making ERP a connected application. by John Burke, Group Vice President, Applications Business Unit

  - by arungupta

  Hot off the press ... Java EE 6 Pocket Guide from 'OReilly Media is now available in Paperback and Kindle Edition. Here are the book details: Release Date: Sep 21, 2012 Language: English Pages: 208 Print ISBN: 978-1-4493-3668-4 | ISBN 10:1-4493-3668-X Ebook ISBN:978-1-4493-3667-7 | ISBN 10:1-4493-3667-1 The book provides a comprehensive summary of the Java EE 6 platform. Main features of different technologies from the platform are explained and accompanied by tons of samples. A chapter is dedicated to Managed Beans, Servlets, Java Persistence API, Enterprise JavaBeans, Contexts and Dependency Injection, JavaServer Faces, SOAP-Based Web Services, RESTful Web Services, Java Message Service, and Bean Validation in that format. Many thanks to Markus Eisele, John Yeary, and Bert Ertman for reviewing and providing valuable comments. This book was not possible without their extensive feedback! This book was mostly written by compiling my blogs, material from 2-day workshops, and several hands-on workshops around the world. The interactions with users of different technologies and whiteboard discussions with different specification leads helped me understand the technology better. Many thanks to them for helping me be a better user! The long international flights during my travel around the world proved extremely useful for authoring the content. No phone, no email, no IM, food served on the table, power outlet = a perfect recipe for authoring ;-) Markus wrote a detailed review of the book. He was one of the manuscript reviewers of the book as well and provided valuable guidance. Some excerpts from his blog: It covers the basics you need to know of Java EE 6 and gives good examples of all relevant parts. ... This is a pocket guide which is comprehensively written. I could follow all examples and it was a good read overall. No complicated constructs and clear writing. ... GO GET IT! It is the only book you probably will need about Java EE 6! It is comprehensive, wonderfully written and covers everything you need in your daily work. It is not a complete reference but provides a great shortcut to the things you need to know. To me it is a good beginners guide and also works as a companion for advanced users. Here is the first tweet feedback ... Jeff West was super prompt to place the first pre-order of my book, pretty much the hour it was announced. Thank you Jeff! @mike_neck posted the very first tweet about the book, thanks for that! The book is now available in Paperback and Kindle Edition from the following websites: O'Reilly Media (Ebook, Print & Ebook, Print) Amazon.com (Kindle Edition and Paperback) Barnes and Noble Overstock (1% off Amazon) Buy.com Booktopia.com Tower Books Angus & Robertson Shopping.com Here is how I can use your help: Help spread the word about the book If you bought a Paperback or downloaded Kindle Edition, then post your review here.
