• October in Review

  - by Richard Bingham

  With OpenWorld over October was time to get back to serious work for everyone, including the Fusion Applications Developer Relations team. Don't forget the OpenWorld content is still available, including presentation downloads, for a limited period of time so be sure to grab anything you found useful or take another scan for anything you might have missed. Of all the announcements, the continued evolution of the Oracle Cloud services for extending and integrating with Fusion Applications is increasing in popularity, and certainly the Cloud Marketplace is something we're becoming involved in. More details to follow. Fusion Concepts Last week Vik from our team started the new "Fusion Concepts" series of articles, providing those new to Fusion Applications an explanation of the architectural basics, with the aim to reduce the learning curve and lay the platform for more efficient and effective development. The series begun with an insightful first post on the different schemas that exist in the Fusion Applications database. Look out for upcoming posts on multi-lingual entities, profile options, look-ups and more. New Learning Resources Our YouTube channel continued to expand with more 'how to' videos on using page composer, extending the Simplified UI (aka FUSE), and integrating BI reports and analytics. Also the Oracle Learning Library is now well established as a central resource for knowledge, now with thousands of tutorials, videos, and documents. Of particular note are the great new extensibility-related videos added by the CRM Product Management team, including more on the ever-expanding capabilities of Application Composer. To see some examples of these search using keyword 'customization' or the product 'Sales Cloud'. Finally on learning resources, as Oliver mentioned the Oracle Press book on Fusion Application Customization and Extensibility is now available for pre-order on Amazon (due out 1st Jan). Out And About October also saw us attend the annual Apps Conference held by the UK Oracle User Group in London. Interestingly there was an Applications Transformation stream of sessions and content that included Fusion Applications with all the latest in the Oracle Applications evolution, as always focused around the three tenets of social, mobile, and cloud. Read more in Richard's post-event write up. Other teams around Oracle have also been busy. Angelo from the Platform Technical Services group has done quite a bit of work using web services with Fusion SaaS and has published many interesting findings on his blog. It's definitely recommended reading if you are working on any related integration projects. The middleware-for-applications group has built a new tool called "AppAdvantage" offering an online assessment of your use of Fusion Middleware technologies with Oracle Applications. As the popularity of integrating cloud applications with on-premises systems continued to grow, leveraging existing middleware technologies (and licenses) to support the integration solution is likely to be of paramount importance. Similarly the "Build Enterprise Application Extensions with Ease" section of the related webpage has AppsUX director Killan Evers speaking about customization using the composer tools. Both are useful resources for those just getting started with a move to Fusion Applications. The Oracle A-Team, specialists in middleware technical architecture, always publish superb content via their 'chronicles' site, now with a substantial amount specifically related to Fusion Applications. Click on the Fusion Applications menu on the top right of their homepage to see more. Last month of particular note was an article on customizing the timeout pop-up message that shows to inactive users, providing design-time insight and easy-to-follow steps. Finally if you're looking at using Oracle Middleware and Cloud to tailor and extend your applications then you may also be interested in this new blog post on the roadmap for Oracle SOA and the latest on-demand Cloud Development webcast.

• SQL SERVER – How to Get SQL Server Restart Notification?

  - by Pinal Dave

  Few days back my friend called me to know if there is any tool which can be used to get restart notification about SQL in their environment. I told that SQL Server can do it by itself with some configurations. He was happy and surprised to know that he need not spend any extra money. In SQL Server, we can configure stored procedure(s) to run at start-up of SQL Server. This blog would give steps to achieve how to achieve it. There are many situations where this feature can be used. Below are few. Logging SQL Server startup timings Modify data in some table during startup (i.e. table in tempdb) Sending notification about SQL start. Step 1 – Enable ‘scan for startup procs’ This can be done either using T-SQL or User Interface of Management Studio. EXEC sys.sp_configure N'Show Advanced Options', N'1' GO RECONFIGURE WITH OVERRIDE GO EXEC sys.sp_configure N'scan for startup procs', N'1' GO RECONFIGURE WITH OVERRIDE GO Below is the interface to change the setting. We need to go to “Server” > “Properties” and use “Advanced” tab. “Scan for Startup Procs” is the parameter under “Miscellaneous” section as shown below. We need to make value as “True” and hit OK. Step 2 – Create stored procedure It’s important to note that the procedure is executed after recovery is finished for ALL databases. Here is a sample stored procedure. You can use your own logic in the procedure. CREATE PROCEDURE SQLStartupProc AS BEGIN CREATE TABLE ##ThisTableShouldAlwaysExists (AnyColumn INT) END Step 3 – Set Procedure to run at startup We need to use sp_procoption to mark the procedure to run at startup. Here is the code to let SQL know that this is startup proc. sp_procoption 'SQLStartupProc', 'startup', 'true' This can be used only for procedures in master database. Msg 15398, Level 11, State 1, Procedure sp_procoption, Line 89 Only objects in the master database owned by dbo can have the startup setting changed. We also need to remember that such procedure should not have any input/output parameter. Here is the error which would be raised. Msg 15399, Level 11, State 1, Procedure sp_procoption, Line 107 Could not change startup option because this option is restricted to objects that have no parameters. Verification Here is the query to find which procedures is marked as startup procedures. SELECT name FROM sys.objects WHERE OBJECTPROPERTY(OBJECT_ID, 'ExecIsStartup') = 1 Once this is done, I have restarted SQL instance and here is what we would see in SQL ERRORLOG Launched startup procedure 'SQLStartupProc'. This confirms that stored procedure is executed. You can also notice that this is done after all databases are recovered. Recovery is complete. This is an informational message only. No user action is required. After few days my friend again called me and asked – I want to turn this OFF? Use comments section and post the answer for him.  Reference: Pinal Dave (http://blog.sqlauthority.com)Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, SQL Utility, T SQL

• Lead, Follow, or Get out of the way

  - by Daniel Moth

  This is one of the sayings (attributed to Thomas Paine) that totally resonated with me from the first time I heard it, which was only 3 years ago during some training course at work: "Lead, Follow, or Get out of the way" You'll find many books with this title and you'll find it quoted by politicians and other leaders in various countries at various times... the quote is open to interpretation and works on many levels. To set the tone of what this means to me, I'll use a simple micro example: In any given conversation, you are either leading it or following it, at different times/snapshots of the conversation. If you are not willing or able to lead it, and you are not willing or able to follow it, then you should depart. The bad alternative which this guidance encourages you NOT to do is to stick around and obstruct progress by not following, not leading, and simply complaining or trying to derail the discussion in no particular direction. The same pattern applies at your position/role at work. Either follow your management/leadership team, or try to lead them to what you think is a better place, or change jobs. Don't stick around complaining about the direction things are going, while not actively trying to either change things or make peace with it. In the previous paragraph you can replace the word "your management" with "the people reporting to you" and the guidance still holds. Either lead your direct reports to where you think they should go, or follow their lead, or change jobs. Complaining about folks not taking direction while doing nothing is not a maintainable state. To me this quote is not about a permanent state, it is not about some people always leading and some always following: It is about a role/hat that anybody can play/wear at any given moment. One minute I am leading you, the next I am following you, and the next we are both following someone else and so on... When there is disagreement, debate the different directions for as long as it takes for you to be comfortable that you can either follow or lead. If you don't become comfortable with either of those, get out of the way. Something to remember is that it is impossible to learn how to lead well, without learning how to follow well (probably deserves its own blog entry)... Things go wrong when someone thinks that they must always be leading, or when everybody wants to follow and nobody steps up to lead... Things go wrong when more than one person wants to lead and they don't try to reach agreement on a shared direction, stubbornly sticking to their guns pulling the rest of the team in multiple directions... Things go wrong when more than one person wants to lead and after numerous and lengthy discussions, none of them decides to follow or get out of the way... Things go wrong when people don't want to lead, don't want to follow, and insist on sticking around... While there are a few ways things that can go wrong as enumerated in the previous paragraph, the most common one in my experience is the last one I mentioned. You'll recognize these folks as the ones that always complain about everything that is wrong with their company/product but do nothing about it. Every time you hear someone giving feedback on how something is wrong or suboptimal, ask them "So now that you identified the problem, what do you think the solution is and what are you doing to drive us to that solution?" The next time things start going wrong, step up and remind everyone: Lead, Follow, or Get out of the way. For more perspectives, and for input to help you form your own interpretation, search the web for this phrase to see in what contexts it is being used (bing, google). Finally, regardless of your political views, I hope you can appreciate if only as an example this perspective of someone leading by actually getting out of the way. Comments about this post by Daniel Moth welcome at the original blog.

• Moving from Silverlight 4 Beta to RC - Part 1

  The other day I had finished up my Task-It Webinar, written a few blog posts, and knew the time had come to move from my Silverlight 4 Beta environment up to the latest RC (release candidate) bits that were released last Monday. What disappointed me when I went to the Silverlight 4 Information Page is that it told me what to install, but not what to uninstall first. Uninstalling I'm not entirely sure if I had to uninstall anything, or if installing the new stuff would just work, but in poking around the web I found posts stating that you must uninstall the following items first. Unfortunately I'm going by memory here and have not been able to find my way back to the magic page I found in the myriad of posts that I went through: Microsoft VisualStudio Beta 2 Microsoft .NET Framework 4 Extended (apparently this must be done *before* the next one) Microsoft .NET Framework Client Profile Microsoft Silverlight 4 Tools for Visual Studio 2010 WCF RIA Services Preview for Visual Studio 2010 While I was at it, I removed a bunch of other stuff, like Blend 3, Blend 4, the SDK's associated with them, and a bunch other stuff that was old. Of course, I didn't really want/need to keep any Silverlight 3 stuff around as I am developing Task-It in Silverlight 4. If I need a Silverlight 3 environment at some point I'll set it up in a virtual environment. NOTE: One thing that I did not uninstall is the Microsoft Silverlight 4 Toolkit November 2009. The reason is that they have not released the March version yet, so if you uninstall this, youll end up having to reinstall it. Installing OK, now that I had all of that old stuff off my machine, now it was time to get the new stuff. For this part I liked Tim Heuer's post, A Guide to What has Changed in Silverlight 4 RC better than the Silverlight 4 Information Page. VisualStudio 2010 RC - I installed Ultimate, but you may not need that version. No harm, it's free for now anyway. I downloaded the .exe and the 3 .rar files, then ran the .exe. I then extracted the contents of the ISO (using WinZip) to a new directory, and now had Setup.exe, a bunch of .cab files and some other assorted stuff. I simply ran Setup.exe and chose custom install (only because I wanted to uncheck Visual C++...I don't really have a need for that) Silverlight 4 Tools for Visual Studio 2010 - As mentioned in Tim's blog post, this installs this installs Silverlight developer runtime, SDK, tools, and this installs Silverlight developer runtime, SDK, tools, and WCF RIA Services. WCF RIA Services Toolkit March 2010 - I'm not sure if/when I'll need any of this stuff, but no harm in installing it anyway. Expression Blend 4 beta - Only if you plan to use Blend, which I do. Windows Phone Developer Tools - Only if you are interested in playing with Windows Phone 7 development. Wrap Up Hopefully I got those steps right. If anyone finds anything I've missed, please just add a comment to this post and I'll update it accordingly.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Oracle MAA Part 1: When One Size Does Not Fit All

  - by JoeMeeks

  The good news is that Oracle Maximum Availability Architecture (MAA) best practices combined with Oracle Database 12c (see video) introduce first-in-the-industry database capabilities that truly make unplanned outages and planned maintenance transparent to users. The trouble with such good news is that Oracle’s enthusiasm in evangelizing its latest innovations may leave some to wonder if we’ve lost sight of the fact that not all database applications are created equal. Afterall, many databases don’t have the business requirements for high availability and data protection that require all of Oracle’s ‘stuff’. For many real world applications, a controlled amount of downtime and/or data loss is OK if it saves money and effort. Well, not to worry. Oracle knows that enterprises need solutions that address the full continuum of requirements for data protection and availability. Oracle MAA accomplishes this by defining four HA service level tiers: BRONZE, SILVER, GOLD and PLATINUM. The figure below shows the progression in service levels provided by each tier. Each tier uses a different MAA reference architecture to deploy the optimal set of Oracle HA capabilities that reliably achieve a given service level (SLA) at the lowest cost.  Each tier includes all of the capabilities of the previous tier and builds upon the architecture to handle an expanded fault domain. Bronze is appropriate for databases where simple restart or restore from backup is ‘HA enough’. Bronze is based upon a single instance Oracle Database with MAA best practices that use the many capabilities for data protection and HA included with every Oracle Enterprise Edition license. Oracle-optimized backups using Oracle Recovery Manager (RMAN) provide data protection and are used to restore availability should an outage prevent the database from being able to restart. Silver provides an additional level of HA for databases that require minimal or zero downtime in the event of database instance or server failure as well as many types of planned maintenance. Silver adds clustering technology - either Oracle RAC or RAC One Node. RMAN provides database-optimized backups to protect data and restore availability should an outage prevent the cluster from being able to restart. Gold raises the game substantially for business critical applications that can’t accept vulnerability to single points-of-failure. Gold adds database-aware replication technologies, Active Data Guard and Oracle GoldenGate, which synchronize one or more replicas of the production database to provide real time data protection and availability. Database-aware replication greatly increases HA and data protection beyond what is possible with storage replication technologies. It also reduces cost while improving return on investment by actively utilizing all replicas at all times. Platinum introduces all of the sexy new Oracle Database 12c capabilities that Oracle staff will gush over with great enthusiasm. These capabilities include Application Continuity for reliable replay of in-flight transactions that masks outages from users; Active Data Guard Far Sync for zero data loss protection at any distance; new Oracle GoldenGate enhancements for zero downtime upgrades and migrations; and Global Data Services for automated service management and workload balancing in replicated database environments. Each of these technologies requires additional effort to implement. But they deliver substantial value for your most critical applications where downtime and data loss are not an option. The MAA reference architectures are inherently designed to address conflicting realities. On one hand, not every application has the same objectives for availability and data protection – the Not One Size Fits All title of this blog post. On the other hand, standard infrastructure is an operational requirement and a business necessity in order to reduce complexity and cost. MAA reference architectures address both realities by providing a standard infrastructure optimized for Oracle Database that enables you to dial-in the level of HA appropriate for different service level requirements. This makes it simple to move a database from one HA tier to the next should business requirements change, or from one hardware platform to another – whether it’s your favorite non-Oracle vendor or an Oracle Engineered System. Please stay tuned for additional blog posts in this series that dive into the details of each MAA reference architecture. Meanwhile, more information on Oracle HA solutions and the Maximum Availability Architecture can be found at: Oracle Maximum Availability Architecture - Webcast Maximize Availability with Oracle Database 12c - Technical White Paper

• Big Data – ClustrixDB – Extreme Scale SQL Database with Real-time Analytics, Releases Software Download – NewSQL

  - by Pinal Dave

  There are so many things to learn and there is so little time we all have. As we have little time we need to be selective to learn whatever we learn. I believe I know quite a lot of things in SQL but I still do not know what is around SQL. I have started to learn about NewSQL recently. If you wonder what is NewSQL I encourage all of you to read my blog post about NewSQL over here Big Data – Buzz Words: What is NewSQL – Day 10 of 21. NewSQL databases are quickly becoming popular – providing the scale of NoSQL with the SQL features and transactions. As a part of learning NewSQL database, I have recently started to learn about ClustrixDB. ClustrixDB has been the most mature NewSQL database used by some of the largest internet sites in the world for over 3 years, with extensive SQL support. In addition to scale, it provides fast real-time analytics by bringing massively parallel processing (MPP), available only in warehousing databases, to the transactional database. The reason I am more intrigued about learning ClustrixDB is their recent announcement on Oct 31. ClustrixDB was only available as an appliance, but now with their software release on Oct 31, everyone can use it. It is now available as forever free for up to 12 cores with community support, and there is a 45 day trial for unlimited cluster sizes. With the forever free world, I am indeed interested in ClustrixDB now. I know that few of the leading eCommerce sites in the world uses them for their transactional database. Here are few of the details I have quickly noted for ClustrixDB. ClustrixDB allows user to: Scale by simply adding nodes to the cluster with a single command Run billions of transactions a day Run fast real-time analytics Achieve high-availability with recovery from node failure Manages itself Easily migrate from MySQL as it is nearly plug-and-play compatible, use MySQL drivers, tools and replication. While I was going through the documentation I realized that ClustrixDB also has extensive support for SQL features including complex queries involving joins on a dozen or more tables, aggregates, sorts, sub-queries. It also supports stored procedures, triggers, foreign keys, partitioned and temporary tables, and fully online schema changes. It is indeed a very matured product and SQL solution. Indeed Clusterix sound very promising solution, I decided to dig a bit deeper to understand who are current customers of the Clustrix as they exist in the industry for quite a few years. Their client list is indeed very interesting and here is my quick research about them. Twoo.com – Europe’s largest social discovery (dating) site runs 4.4 Billion Transactions a day with table sizes over a Terabyte, on a 168 core cluster. EngageBDR – Top 3 in the online advertising category uses ClustrixDB to serve 6.9 billion ads a day through real-time bidding platform. Their reports went from 4 hours to 15 seconds. NoMoreRack – Top 2 fastest growing e-commerce company in US used ClustrixDB for high availability and fast growth through Amazon cloud. MakeMyTrip – India’s leading travel site runs on ClustrixDB with two clusters running as multi-master in Chennai and Bangalore. Many enterprises such as AOL, CSC, Rakuten, Symantec use ClustrixDB when their applications need scale. I must accept that I am impressed with the information I have learned so far and now is the time to do some hand’s on experience with their product. I want to learn this technology so in future when it is about NewSQL, I know what I am talking about. Read more why Clustrix explains why you ClustrixDB might be the right database for you. Download ClustrixDB with me today and install it on your machine so in future when we discuss the technical aspects of it, we all are on the same page. The software can be downloaded here.

• Oracle GoldenGate Active-Active Part 1

  - by Nick_W

  My name is Nick Wagner, and I'm a recent addition to the Oracle Maximum Availability Architecture (MAA) product management team.  I've spent the last 15+ years working on database replication products, and I've spent the last 10 years working on the Oracle GoldenGate product.  So most of my posting will probably be focused on OGG.  One question that comes up all the time is around active-active replication with Oracle GoldenGate.  How do I know if my application is a good fit for active-active replication with GoldenGate?   To answer that, it really comes down to how you plan on handling conflict resolution.  I will delve into topology and deployment in a later blog, but here is a simple architecture: The two most common resolution routines are host based resolution and timestamp based resolution. Host based resolution is used less often, but works with the fewest application changes.  Think of it like this: any transactions from SystemA always take precedence over any transactions from SystemB.  If there is a conflict on SystemB, then the record from SystemA will overwrite it.  If there is a conflict on SystemA, then it will be ignored.  It is quite a bit less restrictive, and in most cases, as long as all the tables have primary keys, host based resolution will work just fine.  Timestamp based resolution, on the other hand, is a little trickier. In this case, you can decide which record is overwritten based on timestamps. For example, does the older record get overwritten with the newer record?  Or vice-versa?  This method not only requires primary keys on every table, but it also requires every table to have a timestamp/date column that is updated each time a record is inserted or updated on the table.  Most homegrown applications can always be customized to include these requirements, but it's a little more difficult with 3rd party applications, and might even be impossible for large ERP type applications.  If your database has these features - whether it’s primary keys for host based resolution, or primary keys and timestamp columns for timestamp based resolution - then your application could be a great candidate for active-active replication.  But table structure is not the only requirement.  The other consideration applies when there is a conflict; i.e., do I need to perform any notification or track down the user that had their data overwritten?  In most cases, I don't think it's necessary, but if it is required, OGG can always create an exceptions table that contains all of the overwritten transactions so that people can be notified. It's a bit of extra work to implement this type of option, but if the business requires it, then it can be done. Unless someone is constantly monitoring this exception table or has an automated process in dealing with exceptions, there will be a delay in getting a response back to the end user. Ideally, when setting up active-active resolution we can include some simple procedural steps or configuration options that can reduce, or in some cases eliminate the potential for conflicts.  This makes the whole implementation that much easier and foolproof.  And I'll cover these in my next blog.

• SQLAuthority News – Live Virtual Classroom New Trend in Technology

  - by nupurdave

  This blog post is by Nupur Dave, who is housewife and works from home. Changing times and a super busy lifestyle have rendered most of us powerless when it comes to doing what we love to do. I feel that a man never ceases to learn and his sole aim is to seek knowledge, and keep growing. However, our tight schedules and packed calendars mean that we really have to struggle to take some time out and follow the path towards learning. Like all working professionals with a family to take care of, I hardly found time to pursue my interests. However, it was getting increasingly important for me to upgrade my skills, not only for my personal quest for knowledge but to also substantiate my professional standing. When I came to know about Koenig Live Virtual Classroom from friends, it piqued my interest. I felt like it was the answer to all my concerns. Without wasting a single minute, I contacted Koenig for a demo class. Here are some of the highlights of Koenig LVC which instantly struck a chord in me: Online Training – Koenig offers 1-on-1 Online Training with the instructor at the other end. Doesn’t matter where I am sitting, in my office or at home, I can connect to my trainer from anywhere. Flexible Timings – The most comfortable part is you get to choose the time that suits you best. Economical -  No need to travel a thousand miles, the experts are right here on your computer screen. So no extra cost of travel, lodging and meals. 24X7 Lab Access: This is again a great feature that proved to be very beneficial in gaining a practical understanding of the subject. Powered by a data center, this facility offers students much to look forward to. 300+ Full Time Certified Experts: Be assured that you are learning from the best people in the industry.

• Microsoft Certifications &ndash; how to prep? and why?

  - by Kelly Jones

  I often get asked by my colleagues, “how do you prepare for Microsoft exams?” Well, the answer for me is a little complicated, so I thought I’d write up here what I do. The first thing I do is go to Microsoft’s website to find the exam that I need to take.  If you’re looking to get a particular certification, then their site lists the exam or exams that you’ll need to pass.  If you’ve already taken an exam, you can log onto the MCP website and use their certification planner.  This little tool tells you what tests you need, based on the exams you’ve already passed.  It is very helpful with the certifications that are multiple tests and especially ones that have electives. Once you’ve identified the test, you can use Microsoft’s website to see the topics that it covers.  This is a good outline to follow when you study.  I’ll keep this handy to reference back throughout my studying to make sure that I’m covering all the topics I need to know. The next step is probably where I am a little different from others.  IF the exam outline covers material that I’ve already been working with, then I’ll skip a lot of the studying and go directly to the practice tests.  However, if I’m looking at the outline and wondering how in the world do you do that? – then it’s time to hit the books. So, where to find study materials?  Try typing in the exam number into any search engine.  You’ll typically find a ton of resources.  If you’re lucky, you’ll find books that others recommend based on their studying and exam experience.  As a Sogeti employee, I have access to three really good resources: an internal company list of all of the consultants who have passed particular tests (on our Connex website), Books 24x7, and Transcender practice exams. Once my studying is done (either through books or experience), I’ll go through the practice exams.  I find them really helpful in getting my knowledge lined up to the thinking process that the exam writers use.  If I’m relying on my experience, then this really helps me to identify gaps in my knowledge that I’ll need to fill. That’s about it.  If I’m doing ok on the practice exams, then I’ll take the real thing.  I’ve found that the practice exams are usually more difficult than then real thing. Oh – one other thing I do related to Microsoft exams – I try to take any beta exams that Microsoft makes available that fall into my skill set.  Microsoft has started a blog to announce these and the seats usually fill up really quick.  The blog is at http://blogs.technet.com/betaexams/ . You don’t get your results instantly, like a normal exam, instead you have to wait for everyone to finish taking the beta exams and for Microsoft to determine which questions they are using and which they are dropping.  So, be prepared to wait six to eight weeks for your results.

• PowerShell Script To Find Where SharePoint 2010 Features Are Activated

  - by Brian Jackett

  The script on this post will find where features are activated within your SharePoint 2010 farm.   Problem    Over the past few months I’ve gotten literally dozens of emails, blog comments, or personal requests from people asking “how do I find where a SharePoint feature has been activated?”  I wrote a script to find which features are installed on your farm almost 3 years ago.  There is also the Get-SPFeature PowerShell commandlet in SharePoint 2010.  The problem is that these only tell you if a feature is installed not where they have been activated.  This is especially important to know if you have multiple web applications, site collections, and /or sites.   Solution    The default call (no parameters) for Get-SPFeature will return all features in the farm.  Many of the parameter sets accept filters for specific scopes such as web application, site collection, and site.  If those are supplied then only the enabled / activated features are returned for that filtered scope.  Taking the concept of recursively traversing a SharePoint farm and merging that with calls to Get-SPFeature at all levels of the farm you can find out what features are activated at that level.  Store the results into a variable and you end up with all features that are activated at every level.    Below is the script I came up with (slight edits for posting on blog).  With no parameters the function lists all features activated at all scopes.  If you provide an Identity parameter you will find where a specific feature is activated.  Note that the display name for a feature you see in the SharePoint UI rarely matches the “internal” display name.  I would recommend using the feature id instead.  You can download a full copy of the script by clicking on the link below.    Note: This script is not optimized for medium to large farms.  In my testing it took 1-3 minutes to recurse through my demo environment.  This script is provided as-is with no warranty.  Run this in a smaller dev / test environment first.   001 002 003 004 005 006 007 008 009 010 011 012 013 014 015 016 017 018 019 020 021 022 023 024 025 026 027 028 029 030 031 032 033 034 035 036 037 038 039 040 041 042 043 044 045 046 047 048 049 050 051 052 053 054 055 056 057 058 059 060 061 062 063 064 065 066 067 068 function Get-SPFeatureActivated { # see full script for help info, removed for formatting [CmdletBinding()] param(   [Parameter(position = 1, valueFromPipeline=$true)]   [Microsoft.SharePoint.PowerShell.SPFeatureDefinitionPipeBind]   $Identity )#end param   Begin   {     # declare empty array to hold results.

• Consumer Oriented Search In Oracle Endeca Information Discovery – Part 1

  - by Bob Zurek

  Information Discovery, a core capability of Oracle Endeca Information Discovery, enables business users to rapidly search, discover and navigate through a wide variety of big data including structured, unstructured and semi-structured data. One of the key capabilities, among many, that differentiate our solution from others in the Information Discovery market is our deep support for search across this growing amount of varied big data. Our method and approach is very different than classic simple keyword search that is found in may information discovery solutions. In this first part of a series on the topic of search, I will walk you through many of the key capabilities that go beyond the simple search box that you might experience in products where search was clearly an afterthought or attempt to catch up to our core capabilities in this area. Lets explore. The core data management solution of Oracle Endeca Information Discovery is the Endeca Server, a hybrid search-analytical database that his highly scalable and column-oriented in nature. We will talk in more technical detail about the capabilities of the Endeca Server in future blog posts as this post is intended to give you a feel for the deep search capabilities that are an integral part of the Endeca Server. The Endeca Server provides best-of-breed search features aw well as a new class of features that are the first to be designed around the requirement to bridge structured, semi-structured and unstructured big data. Some of the key features of search include type a heads, automatic alphanumeric spell corrections, positional search, Booleans, wildcarding, natural language, and category search and query classification dialogs. This is just a subset of the advanced search capabilities found in Oracle Endeca Information Discovery. Search is an important feature that makes it possible for business users to explore on the diverse data sets the Endeca Server can hold at any one time. The search capabilities in the Endeca server differ from other Information Discovery products with simple “search boxes” in the following ways: The Endeca Server Supports Exploratory Search.  Enterprise data frequently requires the user to explore content through an ad hoc dialog, with guidance that helps them succeed. This has implications for how to design search features. Traditional search doesn’t assume a dialog, and so it uses relevance ranking to get its best guess to the top of the results list. It calculates many relevance factors for each query, like word frequency, distance, and meaning, and then reduces those many factors to a single score based on a proprietary “black box” formula. But how can a business users, searching, act on the information that the document is say only 38.1% relevant? In contrast, exploratory search gives users the opportunity to clarify what is relevant to them through refinements and summaries. This approach has received consumer endorsement through popular ecommerce sites where guided navigation across a broad range of products has helped consumers better discover choices that meet their, sometimes undetermined requirements. This same model exists in Oracle Endeca Information Discovery. In fact, the Endeca Server powers many of the most popular e-commerce sites in the world. The Endeca Server Supports Cascading Relevance. Traditional approaches of search reduce many relevance weights to a single score. This means that if a result with a good title match gets a similar score to one with an exact phrase match, they’ll appear next to each other in a list. But a user can’t deduce from their score why each got it’s ranking, even though that information could be valuable. Oracle Endeca Information Discovery takes a different approach. The Endeca Server stratifies results by a primary relevance strategy, and then breaks ties within a strata by ordering them with a secondary strategy, and so on. Application managers get the explicit means to compose these strategies based on their knowledge of their own domain. This approach gives both business users and managers a deterministic way to set and understand relevance. Now that you have an understanding of two of the core search capabilities in Oracle Endeca Information Discovery, our next blog post on this topic will discuss more advanced features including set search, second-order relevance as well as an understanding of faceted search mechanisms that include queries and filters.

• 3 Incredibly Useful Projects to jump-start your Kinect Development.

  - by mbcrump

  I’ve been playing with the Kinect SDK Beta for the past few days and have noticed a few projects on CodePlex worth checking out. I decided to blog about them to help spread awareness. If you want to learn more about Kinect SDK then you check out my”Busy Developer’s Guide to the Kinect SDK Beta”. Let’s get started:   KinectContrib is a set of VS2010 Templates that will help you get started building a Kinect project very quickly. Once you have it installed you will have the option to select the following Templates: KinectDepth KinectSkeleton KinectVideo Please note that KinectContrib requires the Kinect for Windows SDK beta to be installed. Kinect Templates after installing the Template Pack. The reference to Microsoft.Research.Kinect is added automatically.  Here is a sample of the code for the MainWindow.xaml in the “Video” template: <Window x:Class="KinectVideoApplication1.MainWindow" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="480" Width="640"> <Grid> <Image Name="videoImage"/> </Grid> </Window> and MainWindow.xaml.cs using System; using System.Windows; using System.Windows.Media; using System.Windows.Media.Imaging; using Microsoft.Research.Kinect.Nui; namespace KinectVideoApplication1 { public partial class MainWindow : Window { //Instantiate the Kinect runtime. Required to initialize the device. //IMPORTANT NOTE: You can pass the device ID here, in case more than one Kinect device is connected. Runtime runtime = new Runtime(); public MainWindow() { InitializeComponent(); //Runtime initialization is handled when the window is opened. When the window //is closed, the runtime MUST be unitialized. this.Loaded += new RoutedEventHandler(MainWindow_Loaded); this.Unloaded += new RoutedEventHandler(MainWindow_Unloaded); //Handle the content obtained from the video camera, once received. runtime.VideoFrameReady += new EventHandler<Microsoft.Research.Kinect.Nui.ImageFrameReadyEventArgs>(runtime_VideoFrameReady); } void MainWindow_Unloaded(object sender, RoutedEventArgs e) { runtime.Uninitialize(); } void MainWindow_Loaded(object sender, RoutedEventArgs e) { //Since only a color video stream is needed, RuntimeOptions.UseColor is used. runtime.Initialize(Microsoft.Research.Kinect.Nui.RuntimeOptions.UseColor); //You can adjust the resolution here. runtime.VideoStream.Open(ImageStreamType.Video, 2, ImageResolution.Resolution640x480, ImageType.Color); } void runtime_VideoFrameReady(object sender, Microsoft.Research.Kinect.Nui.ImageFrameReadyEventArgs e) { PlanarImage image = e.ImageFrame.Image; BitmapSource source = BitmapSource.Create(image.Width, image.Height, 96, 96, PixelFormats.Bgr32, null, image.Bits, image.Width * image.BytesPerPixel); videoImage.Source = source; } } } You will find this template pack is very handy especially for those new to Kinect Development.   Next up is The Coding4Fun Kinect Toolkit which contains extension methods and a WPF control to help you develop with the Kinect SDK. After downloading the package simply add a reference to the .dll using either the WPF or WinForms version. Now you will have access to several methods that can help you save an image: (for example) For a full list of extension methods and properties, please visit the site at http://c4fkinect.codeplex.com/. Kinductor – This is a great application for just learning how to use the Kinect SDK. The project uses MVVM Light and is a great start for those looking how to structure their first Kinect Application. Conclusion: Things are already getting easier for those working with the Kinect SDK. I imagine that after a few more months we will see the SDK go out of beta and allow commercial applications to run using it. I am very excited and hope that you continue reading my blog for more Kinect, WPF and Silverlight news.  Subscribe to my feed

• Web Services Example - Part 1: Declarative

  - by Denis T

  In this edition of the ADF Mobile blog we'll tackle part 1 of our Web Service examples. In this posting we'll take a look at using a declarative SOAP Web Service. Getting the sample code: Just click here to download a zip of the entire project. You can unzip it and load it into JDeveloper and deploy it either to iOS or Android. Please follow the previous blog posts if you need help getting JDeveloper or ADF Mobile installed. Defining our Web Service: First off, we should mention that this sample code is using a public web service provided free by CDYNE Corporation that provides weather forecasts by zipcode. Sometimes this service goes down so please ensure you know it's up before reporting this example isn't working. Let's take a look at the web service.  We created this by using the "Web Service Data Control" from the New Gallery and using this link to this wsdl:  "http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"   This web service has several methods but we're interested in GetCityForecastByZIP which takes a single string parameter for the zipcode and the second method, GetWeatherInformation that enumerates all possible forecast descriptions and associated image URLs.  The latter we'll use in the next edition but we included it here for completeness. Defing the Application: After adding a feature to the adfmf-feature.xml file, we added a taskflow to host the application flow.  This comprises of a home screen with a list with items for each method in the web service, "Forecast by Zip" and "Weather Info".  In this application we've also decided to hide the navigation bar since there is only one feature in the application. Forecast by Zip: The "Forecast By ZIP" option first presents the user with a screen where they can enter a zipcode and when the "Search" button is tapped, it executes the GetCityForecastByZIP method.  This is done by binding an Action binding to that method. The easiest way to accomplish this is to just drag & drop the method from the Data Control palette to the AMX page and drop it as a button and let the framework hook it up for you.  There is an inputText component on the page that is bound to a pageFlowScope variable called "zip".  This is used as the parameter to the Action binding when it is executed.  Because the actionListener attribute of the commandButton executes the Web Service each time, we ensure that the method is invoked every time the button is clicked. Weather Info: Unlike the previous method, this time instead of explictly executing the web service method we are using deferred invocation.  What this means is that we will bind to the results of the method and the framework will execute the method when it the data is required to be rendered.  We do this by simply doing a drag & drop of the results of the GetWeatherInformation to the AMX page.  When the page is rendered and the bindings are resolved the framework invokes the method.  This executes the method only when it is needed and fills the Data Control provider.  Because we never re-execute the method, you can click from Home to Weather Info and back many times and the web service is only ever invoked once. Issues and Possible Improvements: One thing you will quickly realize with this example is that the error handling is done by the framework for you. For simple examples this is fine but for real applications you'll want to customize these error messages.  With the declarative invocation of web services, this is difficult.  This is one aspect we'll address in the second installment of the web service examples where we will show you how to do programmatic invocation which allows you better error handling. Another issue you will notice with this example is that we can enumerate the weather information but there isn't an easy way to use that information to show the corresponding description and image as part of the forecast results.  We'll show you how to do this in the next example.

• Hyper-V for Developers Part 1 Internal Networks

  Over the last year, weve been working with Microsoft to build training and demo content for the next version of Office Communications Server code-named Microsoft Communications Server 14.  This involved building multi-server demo environments in Hyper-V, getting them running on demo servers which we took to TechEd, PDC, and other training events, and sometimes connecting the demo servers to the show networks at those events.  ITPro stuff that should scare the hell out of a developer! It can get ugly when I occasionally have to venture into ITPro land.  Lets leave it at that. Having gone through this process about 10 to 15 times in the last year, I finally have it down.  This blog series is my attempt to put all that knowledge in one place if anything, so I can find it somewhere when I need it again.  Ill start with the most simple scenario and then build on top of it in future blog posts. If youre an ITPro, please resist the urge to laugh at how trivial this is. Internal Hyper-V Networks Lets start simple.  An internal network is one that intended only for the virtual machines that are going to be on that network it enables them to communicate with each other. Create an Internal Network On your host machine, fire up the Hyper-V Manager and click the Virtual Network Manager in the Actions panel. Select Internal and leave all the other default values. Give the virtual network a name, and leave all the other default values. After the virtual network is created, open the Network and Sharing Center and click Change Adapter Settings to see the list of network connections. The only thing I recommend that you do is to give this connection a friendly label, e.g. Hyper-V Internal.  When you have multiple networks and virtual networks on the host machines, this helps group the networks so you can easily differentiate them from each other.  Otherwise, dont touch it, only bad things can happen. Connect the Virtual Machines to the Internal Network Im assuming that you have more than 1 virtual machine already configured in Hyper-V, for example a Domain Controller, and Exchange Server, and a SharePoint Server. What you need to do is basically plug in the network to the virtual machine.  In order to do this, the machine needs to have a virtual network adapter.  If the VM doesnt have a network adapter, open the VMs Settings and click Add Hardware in the left pane.  Choose the virtual network to which to bind the adapter to. If you already have a virtual network adapter on the VM, simply connect it to the virtual network. Assign IP Addresses to the Virtual Machines on the Internal Network Open the Network and Sharing Center on your VM, there should only be 1 network at this time.  Open the Properties of the connection, select Internet Protocol Version 4 (TCP/IPv4) and hit Properties. In this environment, Im assigning IP addresses as 192.168.0.xxx.  This particular VM has an IP address of 192.168.0.40 with a subnet mask of 255.255.255.0, and a DNS Server of 192.168.0.18.  DNS is running on the Domain Controller VM which has an IP address of 192.168.0.18. Repeat this process on every VM in your environment, obviously assigning a unique IP address to each.  In an environment with a domain controller, you should now be able to ping the machines from each other. What Next? After completing this process, heres what you still cannot do: Access the internet from any of the VMs Remote desktop to a VM from the host Remote desktop to a VM over the network In the next post, well take a look configuring an External network adapter on the virtual machines.  Well then build on top of that so that you can RDP into the VMs from the host machine and over the network.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Making it GREAT! Oracle Partners Building Apps Workshop with UX and ADF in UK

  - by ultan o'broin

  Yes, making is what it's all about. This time, Oracle Partners in the UK were making great looking usable apps with the Oracle Applications Development Framework (ADF) and user experience (UX) toolkit. And what an energy-packed and productive event at the Oracle UK, Thames Valley Park, location it was. Partners learned the fundamentals of enterprise applications UX, why it's important, all about visual design, how to wireframe designs, and then how to build their already-proven designs in ADF. There was a whole day on mobile apps, learning about mobile design principles, free mobile UX and ADF resources from Oracle, and then trying it out. The workshop wrapped up with the latest Release 7 simplified UIs, Mobilytics, and other innovations from Oracle, and a live demo of a very neat ADF Mobile Android app built by an Oracle contractor. And, what a fun two days both Grant Ronald of ADF and myself had in running the workshop with such a great audience, too! I particularly enjoyed the wireframing and visual design sessions interaction; and seeing some outstanding work done by partners. Of note from the UK workshop were innovative design features not seen before and made me all the happier that developers were bringing their own ideas from the consumer IT world of mobility, simplicity, and social to the world of work apps in a smart way within an enterprise methodology too.  Partner wireframe exercise. Applying mobile design principles and UX design patterns means you've already productively making great usable apps! Next, over to Oracle ADF Mobile with it! One simple example from the design of a mobile field service app was that participants immediately saw how the UX and device functionality of the super UK-based app Hailo app could influence their designs (the London cabbie influence maybe?), as well as how we all use maps, cameras, barcode scanners and microphones on our phones could be used in work. And, of course, ADF Mobile has the device integration solutions there too! I wonder will U.S. workshops in Silicon Valley see an Uber UX influence (LOL)! That we also had partners experienced with Oracle Forms who could now offer a roadmap from Forms to Simplified UI and Mobile using ADF, and do it through through the cloud, really made this particular workshop go "ZING!" for me. Many thanks to the Oracle PartnerNetwork (OPN) team for organizing this event with us, and to the representatives of the Oracle Partners that showed and participated so well. That's what I love out this outreach. It's a two-way, solid value-add for all. Interested? Why would partners and developers with ADF skills sign up for this workshop? Here's why: Learn to use the Oracle Applications User Experience design patterns as the usability building blocks for applications development in Oracle Application Development Framework. The workshop enables attendees to build modern and visually compelling desktop and mobile applications that look and behave like Oracle Cloud Applications, and that can co-exist with partner integrations, new, or existing applications deployments. Partners learn to offer customers and clients more than just coded functionality; instead they can provide a complete user experience with a roadmap for continued ROI from applications that also creating more business and attracts the kudos and respect from other makers of apps as they're wowed by the results. So, if you're a partner and interested in attending one of these workshops and benefitting from such learning, as well as having a platform to show off some of your own work, stay well tuned to your OPN channels, to this blog, to the VoX blog, and to the @usableapps Twitter account too. Can't wait?

• Server-Sent Events using GlassFish (TOTD #179)

  - by arungupta

  Bhakti blogged about Server-Sent Events on GlassFish and I've been planning to try it out for past some days. Finally, I took some time out today to learn about it and build a simplistic example showcasing the touch points. Server-Sent Events is developed as part of HTML5 specification and provides push notifications from a server to a browser client in the form of DOM events. It is defined as a cross-browser JavaScript API called EventSource. The client creates an EventSource by requesting a particular URL and registers an onmessage event listener to receive the event notifications. This can be done as shown var url = 'http://' + document.location.host + '/glassfish-sse/simple';eventSource = new EventSource(url);eventSource.onmessage = function (event) { var theParagraph = document.createElement('p'); theParagraph.innerHTML = event.data.toString(); document.body.appendChild(theParagraph);} This code subscribes to a URL, receives the data in the event listener, adds it to a HTML paragraph element, and displays it in the document. This is where you'll parse JSON and other processing to display if some other data format is received from the URL. The URL to which the EventSource is subscribed to is updated on the server side and there are multipe ways to do that. GlassFish 4.0 provide support for Server-Sent Events and it can be achieved registering a handler as shown below: @ServerSentEvent("/simple")public class MySimpleHandler extends ServerSentEventHandler { public void sendMessage(String data) { try { connection.sendMessage(data); } catch (IOException ex) { . . . } }} And then events can be sent to this handler using a singleton session bean as shown: @Startup@Statelesspublic class SimpleEvent { @Inject @ServerSentEventContext("/simple") ServerSentEventHandlerContext<MySimpleHandler> simpleHandlers; @Schedule(hour="*", minute="*", second="*/10") public void sendDate() { for(MySimpleHandler handler : simpleHandlers.getHandlers()) { handler.sendMessage(new Date().toString()); } }} This stateless session bean injects ServerSentEventHandlers listening on "/simple" path. Note, there may be multiple handlers listening on this path. The sendDate method triggers every 10 seconds and send the current timestamp to all the handlers. The client side browser simply displays the string. The HTTP request headers look like: Accept: text/event-streamAccept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3Accept-Encoding: gzip,deflate,sdchAccept-Language: en-US,en;q=0.8Cache-Control: no-cacheConnection: keep-aliveCookie: JSESSIONID=97ff28773ea6a085e11131acf47bHost: localhost:8080Referer: http://localhost:8080/glassfish-sse/faces/index2.xhtmlUser-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/536.5 (KHTML, like Gecko) Chrome/19.0.1084.54 Safari/536.5 And the response headers as: Content-Type: text/event-streamDate: Thu, 14 Jun 2012 21:16:10 GMTServer: GlassFish Server Open Source Edition 4.0Transfer-Encoding: chunkedX-Powered-By: Servlet/3.0 JSP/2.2 (GlassFish Server Open Source Edition 4.0 Java/Apple Inc./1.6) Notice, the MIME type of the messages from server to the client is text/event-stream and that is defined by the specification. The code in Bhakti's blog can be further simplified by using the recently-introduced Twitter API for Java as shown below: @Schedule(hour="*", minute="*", second="*/10") public void sendTweets() { for(MyTwitterHandler handler : twitterHandler.getHandlers()) { String result = twitter.search("glassfish", String.class); handler.sendMessage(result); }} The complete source explained in this blog can be downloaded here and tried on GlassFish 4.0 build 34. The latest promoted build can be downloaded from here and the complete source code for the API and implementation is here. I tried this sample on Chrome Version 19.0.1084.54 on Mac OS X 10.7.3.

• Ops Center 12c - Update - Provisioning Solaris on x86 Using a Card-Based NIC

  - by scottdickson

  Last week, I posted a blog describing how to use Ops Center to provision Solaris over the network via a NIC on a card rather than the built-in NIC.  Really, that was all about how to install Solaris on a SPARC system.  This week, we'll look at how to do the same thing for an x86-based server. Really, the overall process is exactly the same, at least for Solaris 11, with only minor updates. We will focus on Solaris 11 for this blog.  Once I verify that the same approach works for Solaris 10, I will provide another update. Booting Solaris 11 on x86 Just as before, in order to configure the server for network boot across a card-based NIC, it is necessary to declare the asset to associate the additional MACs with the server.  You likely will need to access the server console via the ILOM to figure out the MAC and to get a good idea of the network instance number.  The simplest way to find both of these is to start a network boot using the desired NIC and see where it appears in the list of network interfaces and what MAC is used when it tries to boot.  Go to the ILOM for the server.  Reset the server and start the console.  When the BIOS loads, select the boot menu, usually with Ctrl-P.  This will give you a menu of devices to boot from, including all of the NICs.  Select the NIC you want to boot from.  Its position in the list is a good indication of what network number Solaris will give the device. In this case, we want to boot from the 5th interface (GB_4, net4).  Pick it and start the boot processes.  When it starts to boot, you will see the MAC address for the interface Once you have the network instance and the MAC, go through the same process of declaring the asset as in the SPARC case.  This associates the additional network interface with the server.. Creating an OS Provisioning Plan The simplest way to do the boot via an alternate interface on an x86 system is to do a manual boot.  Update the OS provisioning profile as in the SPARC case to reflect the fact that we are booting from a different interface.  Update, in this case, the network boot device to be GB_4/net4, or the device corresponding to your network instance number.  Configure the profile to support manual network boot by checking the box for manual boot in the OS Provisioning profile. Booting the System Once you have created a profile and plan to support booting from the additional NIC, we are ready to install the server. Again, from the ILOM, reset the system and start the console.  When the BIOS loads, select boot from the Boot Menu as above.  Select the network interface from the list as before and start the boot process.  When the grub bootloader loads, the default boot image is the Solaris Text Installer.  On the grub menu, select Automated Installer and Ops Center takes over from there. Lessons The key lesson from all of this is that Ops Center is a valuable tool for provisioning servers whether they are connected via built-in network interfaces or via high-speed NICs on cards.  This is great news for modern datacenters using converged network infrastructures.  The process works for both SPARC and x86 Solaris installations.  And it's easy and repeatable.

• Fun tips with Analytics

  - by user12620172

  If you read this blog, I am assuming you are at least familiar with the Analytic functions in the ZFSSA. They are basically amazing, very powerful and deep. However, you may not be aware of some great, hidden functions inside the Analytic screen. Once you open a metric, the toolbar looks like this: Now, I’m not going over every tool, as we have done that before, and you can hover your mouse over them and they will tell you what they do. But…. Check this out. Open a metric (CPU Percent Utilization works fine), and click on the “Hour” button, which is the 2nd clock icon. That’s easy, you are now looking at the last hour of data. Now, hold down your ‘Shift’ key, and click it again. Now you are looking at 2 hours of data. Hold down Shift and click it again, and you are looking at 3 hours of data. Are you catching on yet? You can do this with not only the ‘Hour’ button, but also with the ‘Minute’, ‘Day’, ‘Week’, and the ‘Month’ buttons. Very cool. It also works with the ‘Show Minimum’ and ‘Show Maximum’ buttons, allowing you to go to the next iteration of either of those. One last button you can Shift-click is the handy ‘Drill’ button. This button usually drills down on one specific aspect of your metric. If you Shift-click it, it will display a “Rainbow Highlight” of the current metric. This works best if this metric has many ‘Range Average’ items in the left-hand window. Give it a shot. Also, one will sometimes click on a certain second of data in the graph, like this:  In this case, I clicked 4:57 and 21 seconds, and the 'Range Average' on the left went away, and was replaced by the time stamp. It seems at this point to some people that you are now stuck, and can not get back to an average for the whole chart. However, you can actually click on the actual time stamp of "4:57:21" right above the chart. Even though your mouse does not change into the typical browser finger that most links look like, you can click it, and it will change your range back to the full metric. Another trick you may like is to save a certain view or look of a group of graphs. Most of you know you can save a worksheet, but did you know you could Sync them, Pause them, and then Save it? This will save the paused state, allowing you to view it forever the way you see it now.  Heatmaps. Heatmaps are cool, and look like this:  Some metrics use them and some don't. If you have one, and wish to zoom it vertically, try this. Open a heatmap metric like my example above (I believe every metric that deals with latency will show as a heatmap). Select one or two of the ranges on the left. Click the "Change Outlier Elimination" button. Click it again and check out what it does.  Enjoy. Perhaps my next blog entry will be the best Analytic metrics to keep your eyes on, and how you can use the Alerts feature to watch them for you. Steve

• The best computer ever

  - by Jeff

  (This is a repost from my personal blog… wow… I need to write more technical stuff!) About three years and three months ago, I bought a 17" MacBook Pro, and it turned out to be the best computer I've ever owned. You might think that every computer with better specs is automatically better than the last, but that hasn't been my experience. My first one was a Sony, back in the Pentium III days, and it cost an astonishing $2,500. That was even more ridiculous in 1999 dollars. It had a dial-up modem, and a CD-ROM, built-in! It may have even played DVD's. A few years later I bought an HP, and it ended up being a pile of shit. The power connector inside came loose from the board, and on occasion would even short. In 2005, I bought a Dell, and it wasn't bad. It had a really high resolution screen (complete with dead pixels, a problem in those days), and it was the first laptop I felt I could do real work on. When 2006 rolled around, Apple started making computers with Intel CPU's, and I bought the very first one the week it came out. I used Boot Camp to run Windows. I still have it in its box somewhere, and I used it for three years. The current 17" was new in 2009. The goodness was largely rooted in having a big screen with lots of dots. This computer has been the source of hundreds of blog posts, tens of thousands of lines of code, video and photo editing, and of course, a whole lot of Web surfing. It connected to corpnet at Microsoft, WiFi in Hawaii and has presented many a deck. It has traveled with me tens of thousands of miles. Last year, I put a solid state drive in it, and it was like getting a new computer. I can boot up a Windows 7 VM in about 19 seconds. Having 8 gigs of RAM has always been fantastic. Everything about it has been fast and fun. When new, the battery (when not using VM's) could get as much as 10 hours. I can still do 7 without much trouble. After 460 charge cycles, the battery health is still between 85 and 90%. The only real negative has been the size and weight. It's only an inch thick, but naturally it's pretty big with a 17" screen. You don't get battery life like that without a huge battery, either, so it's heavy. It was never a deal breaker, but sometimes a long haul across a large airport, you know you're carrying it. Today, Apple announced a new, thinner and lighter 15" laptop, with twice the RAM and CPU cores, and four times the screen resolution. It basically handles my size and weight issues while retaining the resolution, and it still costs less than my 17" did. So I ordered one. Three years is an excellent run, but I kind of budgeted for a new workhorse this year anyway. So if you're interested in a 17" MacBook Pro with a Core 2 Duo 2.66 GHz CPU, 8 gigs of RAM and a 320 gig hard drive (sorry, I'm keeping the SSD), I have one to sell. They've apparently discontinued the 17", which is going to piss off the video community. It's in excellent condition, with a few minor scratches, but I take care of my stuff.

• Dependency Injection Introduction

  - by MarkPearl

  I recently was going over a great book called “Dependency Injection in .Net” by Mark Seeman. So far I have really enjoyed the book and would recommend anyone looking to get into DI to give it a read. Today I thought I would blog about the first example Mark gives in his book to illustrate some of the benefits that DI provides. The ones he lists are Late binding Extensibility Parallel Development Maintainability Testability To illustrate some of these benefits he gives a HelloWorld example using DI that illustrates some of the basic principles. It goes something like this… class Program { static void Main(string[] args) { var writer = new ConsoleMessageWriter(); var salutation = new Salutation(writer); salutation.Exclaim(); Console.ReadLine(); } } public interface IMessageWriter { void Write(string message); } public class ConsoleMessageWriter : IMessageWriter { public void Write(string message) { Console.WriteLine(message); } } public class Salutation { private readonly IMessageWriter _writer; public Salutation(IMessageWriter writer) { _writer = writer; } public void Exclaim() { _writer.Write("Hello World"); } }   If you had asked me a few years ago if I had thought this was a good approach to solving the HelloWorld problem I would have resounded “No”. How could the above be better than the following…. class Program { static void Main(string[] args) { Console.WriteLine("Hello World"); Console.ReadLine(); } }  Today, my mind-set has changed because of the pain of past programs. So often we can look at a small snippet of code and make judgements when we need to keep in mind that we will most probably be implementing these patterns in projects with hundreds of thousands of lines of code and in projects that we have tests that we don’t want to break and that’s where the first solution outshines the latter. Let’s see if the first example achieves some of the outcomes that were listed as benefits of DI. Could I test the first solution easily? Yes… We could write something like the following using NUnit and RhinoMocks… [TestFixture] public class SalutationTests { [Test] public void ExclaimWillWriteCorrectMessageToMessageWriter() { var writerMock = MockRepository.GenerateMock<IMessageWriter>(); var sut = new Salutation(writerMock); sut.Exclaim(); writerMock.AssertWasCalled(x => x.Write("Hello World")); } }   This would test the existing code fine. Let’s say we then wanted to extend the original solution so that we had a secure message writer. We could write a class like the following… public class SecureMessageWriter : IMessageWriter { private readonly IMessageWriter _writer; private readonly string _secretPassword; public SecureMessageWriter(IMessageWriter writer, string secretPassword) { _writer = writer; _secretPassword = secretPassword; } public void Write(string message) { if (_secretPassword == "Mark") { _writer.Write(message); } else { _writer.Write("Unauthenticated"); } } }   And then extend our implementation of the program as follows… class Program { static void Main(string[] args) { var writer = new SecureMessageWriter(new ConsoleMessageWriter(), "Mark"); var salutation = new Salutation(writer); salutation.Exclaim(); Console.ReadLine(); } }   Our application has now been successfully extended and yet we did very little code change. In addition, our existing tests did not break and we would just need add tests for the extended functionality. Would this approach allow parallel development? Well, I am in two camps on parallel development but with some planning ahead of time it would allow for it as you would simply need to decide on the interface signature and could then have teams develop different sections programming to that interface. So,this was really just a quick intro to some of the basic concepts of DI that Mark introduces very successfully in his book. I am hoping to blog about this further as I continue through the book to list some of the more complex implementations of containers.

• Property overwrite behaviour

  - by jeremyj

  I thought it worth sharing about property overwrite behaviour because i found it confusing at first in the hope of preventing some learning pain for the uninitiated with MSBuild :-)The confusion for me came because of the redundancy of using a Condition statement in a _project_ level property to test that a property has not been previously set. What i mean is that the following two statements are always identical in behaviour, regardless if the property has been supplied on the command line -  <PropertyGroup>    <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>  </PropertyGroup>has the same behaviour regardless of command line override as -  <PropertyGroup>     <PropA>PropA set at project level</PropA>   </PropertyGroup>  i.e. the two above property declarations have the same result whether the property is overridden on the command line or not.To prove this experiment with the following .proj file -<?xml version="1.0" encoding="utf-8"?><Project ToolsVersion="4.0" >  <PropertyGroup>    <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>  </PropertyGroup>  <Target Name="Target1">    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target2">    <PropertyGroup>      <PropA>PropA set in Target2</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target3">    <PropertyGroup>      <PropA Condition=" '$(PropA)' == '' ">PropA set in Target3</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target>  <Target Name="Target4">    <PropertyGroup>      <PropA Condition=" '$(PropA)' != '' ">PropA set in Target4</PropA>    </PropertyGroup>    <Message Text="PropA: $(PropA)"/>  </Target></Project>Try invoking it using both of the following invocations and observe its output -1)>msbuild blog.proj /t:Target1;Target2;Target3;Target42)>msbuild blog.proj /t:Target1;Target2;Target3;Target4 "/p:PropA=PropA set on command line"Then try those two invocations with the following three variations of specifying PropA at the project level -1)  <PropertyGroup>     <PropA Condition=" '$(PropA)' == '' ">PropA set at project level</PropA>   </PropertyGroup> 2)   <PropertyGroup>     <PropA>PropA set at project level</PropA>   </PropertyGroup>3)  <PropertyGroup>     <PropA Condition=" '$(PropA)' != '' ">PropA set at project level</PropA>   </PropertyGroup>

• Web Service Example - Part 3: Asynchronous

  - by Denis T

  In this edition of the ADF Mobile blog we'll tackle part 3 of our Web Service examples.  In this posting we'll take a look at firing the web service asynchronously and then filling in the UI when it completes.  This can be useful when you have data on the device in a local store and want to show that to the user while the application uses lazy loading from a web service to load more data. Getting the sample code: Just click here to download a zip of the entire project.  You can unzip it and load it into JDeveloper and deploy it either to iOS or Android.  Please follow the previous blog posts if you need help getting JDeveloper or ADF Mobile installed.  Note: This is a different workspace than WS-Part2 What's different? In this example, when you click the Search button on the Forecast By Zip option, now it takes you directly to the results page, which is initially blank.  When the web service returns a second or two later the data pops into the UI.  If you go back to the search page and hit Search it will again clear the results and invoke the web service asynchronously.  This isn't really that useful for this particular example but it shows an important technique that can be used for other use cases. How it was done 1)  First we created a new class, ForecastWorker, that implements the Runnable interface.  This is used as our worker class that we create an instance of and pass to a new thread that we create when the Search button is pressed inside the retrieveForecast actionListener handler.  Once the thread is started, the retrieveForecast returns immediately.  2)  The rest of the code that we had previously in the retrieveForecast method has now been moved to the retrieveForecastAsync.  Note that we've also added synchronized specifiers on both these methods so they are protected from re-entrancy. 3)  The run method of the ForecastWorker class then calls the retrieveForecastAsync method.  This executes the web service code that we had previously, but now on a separate thread so the UI is not locked.  If we had already shown data on the screen it would have appeared before this was invoked.  Note that you do not see a loading indicator either because this is on a separate thread and nothing is blocked. 4)  The last but very important aspect of this method is that once we update data in the collections from the data we retrieve from the web service, we call AdfmfJavaUtilities.flushDataChangeEvents().   We need this because as data is updated in the background thread, those data change events are not propagated to the main thread until you explicitly flush them.  As soon as you do this, the UI will get updated if any changes have been queued. Summary of Fundamental Changes In This Application The most fundamental change is that we are invoking and handling our web services in a background thread and updating the UI when the data returns.  This allows an application to provide a better user experience in many cases because data that is already available locally is displayed while lengthy queries or web service calls can be done in the background and the UI updated when they return.  There are many different use cases for background threads and this is just one example of optimizing the user experience and generating a better mobile application.
