• Building a Data Mart with Pentaho Data Integration Video Review by Diethard Steiner, Packt Publishing

Indeed, a video watcher should be familiar with its concepts as the Star Schema, Slowly Changing Dimension types, etc. so I suggest prior to watching this course to consider skimming through the Data Warehouse concepts (if unfamiliar) or even better, read the excellent Ralph’s The Data Warehouse Tooolkit.

Indeed, I even suggest the name of the course should be ‘Building a Data Warehouse with Pentaho’. To successfully complete the course one needs to know some Linux (Ubuntu used in the course), the VI editor and the Bash command shell, but it seems that similar requirements would also apply to the Windows OS. Additionally, knowing some basic SQL would not hurt. As I had said, MonetDB is used in this course several times which seems to be not anymore complex than say MySQL, but based on what I read is very well suited for fast querying big volumes of data thanks to having a columnstore (vertical data storage). I don’t see what else can be a barrier, the material is very digestible. On this note, I must add that the author does not cover how to acquire the software, so here is what I found may help: Pentaho: the free Community Edition must be more than anyone needs to learn it. Or even go into a POC. MonetDB can be downloaded (exists for both, Linux and Windows) from http://goo.gl/FYxMy0 (just see the appropriate link on the left). The author seems to be using Eclipse to run SQL code, one can get it from http://goo.gl/5CcuN. To create, or edit database entities and/or schema otherwise one can use a universal tool called SQuirreL, get it from http://squirrel-sql.sourceforge.net.   Next, I must confess Diethard is very knowledgeable in what he does and beyond. However, there will be some accent heard to the user of the course especially if one’s mother tongue language is English, but it I got over it in a few chapters. I liked the rate at which the material is being presented, it makes me feel I paid for every second Eventually, my impressions are: Pentaho is an awesome ETL offering, it is worth learning it very much (I am an ETL fan and a heavy user of SSIS) MonetDB is nice, it tickles my fancy to know it more Data Warehousing, despite all the BigData tool offerings (Hive, Scoop, Pig on Hadoop), using the traditional tools still rocks Chapters 2 to 6 were the most fun to me with chapter 8 being the most difficult.   In terms of closing, I highly recommend this video to anyone who needs to grasp Pentaho concepts quick, likewise, the course is very well suited for any developer on a “supposed to be done yesterday” type of a project. It is for a beginner to intermediate level ETL/DW developer. But one would need to learn more on Data Warehousing and Pentaho, for such I recommend the 5 star Pentaho Data Integration 4 Cookbook. Enjoy it! Disclaimer: I received this video from the publisher for the purpose of a public review.

• SQL SERVER – UNION ALL and ORDER BY – How to Order Table Separately While Using UNION ALL

  - by pinaldave

  I often see developers trying following syntax while using ORDER BY. SELECT Columns FROM TABLE1 ORDER BY Columns UNION ALL SELECT Columns FROM TABLE2 ORDER BY Columns However the above query will return following error. Msg 156, Level 15, State 1, Line 5 Incorrect syntax near the keyword ‘ORDER’. It is not possible to use two different ORDER BY in the UNION statement. UNION returns single resultsetand as per the Logical Query Processing Phases. However, if your requirement is such that you want your top and bottom query of the UNION resultset independently sorted but in the same resultset you can add an additional static column and order by that column. Let us re-create the same scenario. First create two tables and populated with sample data. USE tempdb GO -- Create table CREATE TABLE t1 (ID INT, Col1 VARCHAR(100)); CREATE TABLE t2 (ID INT, Col1 VARCHAR(100)); GO -- Sample Data Build INSERT INTO t1 (ID, Col1) SELECT 1, 'Col1-t1' UNION ALL SELECT 2, 'Col2-t1' UNION ALL SELECT 3, 'Col3-t1'; INSERT INTO t2 (ID, Col1) SELECT 3, 'Col1-t2' UNION ALL SELECT 2, 'Col2-t2' UNION ALL SELECT 1, 'Col3-t2'; GO If we SELECT the data from both the table using UNION ALL . -- SELECT without ORDER BY SELECT ID, Col1 FROM t1 UNION ALL SELECT ID, Col1 FROM t2 GO We will get the data in following order. However, our requirement is to get data in following order. If we need data ordered by Column1 we can ORDER the resultset ordered by Column1. -- SELECT with ORDER BY SELECT ID, Col1 FROM t1 UNION ALL SELECT ID, Col1 FROM t2 ORDER BY ID GO Now to get the data in independently sorted in UNION ALL let us add additional column OrderKey and use ORDER BY  on that column. I think the description does not do proper justice let us see the example here. -- SELECT with ORDER BY - with ORDER KEY SELECT ID, Col1, 'id1' OrderKey FROM t1 UNION ALL SELECT ID, Col1, 'id2' OrderKey FROM t2 ORDER BY OrderKey, ID GO The above query will give the desired result. Now do not forget to clean up the database by running the following script. -- Clean up DROP TABLE t1; DROP TABLE t2; GO Here is the complete script used in this example. USE tempdb GO -- Create table CREATE TABLE t1 (ID INT, Col1 VARCHAR(100)); CREATE TABLE t2 (ID INT, Col1 VARCHAR(100)); GO -- Sample Data Build INSERT INTO t1 (ID, Col1) SELECT 1, 'Col1-t1' UNION ALL SELECT 2, 'Col2-t1' UNION ALL SELECT 3, 'Col3-t1'; INSERT INTO t2 (ID, Col1) SELECT 3, 'Col1-t2' UNION ALL SELECT 2, 'Col2-t2' UNION ALL SELECT 1, 'Col3-t2'; GO -- SELECT without ORDER BY SELECT ID, Col1 FROM t1 UNION ALL SELECT ID, Col1 FROM t2 GO -- SELECT with ORDER BY SELECT ID, Col1 FROM t1 UNION ALL SELECT ID, Col1 FROM t2 ORDER BY ID GO -- SELECT with ORDER BY - with ORDER KEY SELECT ID, Col1, 'id1' OrderKey FROM t1 UNION ALL SELECT ID, Col1, 'id2' OrderKey FROM t2 ORDER BY OrderKey, ID GO -- Clean up DROP TABLE t1; DROP TABLE t2; GO I am sure there are many more ways to achieve this, what method would you use if you have to face the similar situation?

• Speaker at the German Visual FoxPro Developer Conference 2003

  The following is an excerpt from the UniversalThread conference coverage of the German Visual FoxPro Developer Conference 2003 written by Hans-Otto Lochmann and Armin Neudert. Track: Visual FoxPro and Linux This track consists of 4 sessions presented on one day in one sequence. Originally the Linux portion of this track was to be presented by Whil Hentzen, the well-known publisher, book author and confer-ence speaker. Unfortunately some illness prevented him from joining this DevCon. Rainer got the bad news only on early Friday morning. It was definitely to late to find a replacement among the already invited speaker on such a short notice. So Rainer decided to take over these "three sessions in a row" by himself with "a little help from his friends". He hired a coach for him for the weekend and prepared slides and sessions by himself - the originally planed slides and session material were still in USA. Rainer survived barely an endless disaster of C0000005's due to various wrong configuration settings... At the presentation Jochen Kirstätter helped massively with technical details regarding Linux whereas Rainer did the slides and the presentation. Gerold Lübben then presented the MySQL part - as originally planned. This track concentrated on the how to run Visual FoxPro applications on Linux machines with the help of a Windows emulator like Wine. As more and more people use Linux machines in production (and not just for running servers), more and more invitations to bid for a development job includes the requirement to run the application in a Linux environment. If you would like to participate in such submissions, then you should get familiar with the open source operating system Linux and the open source Data Base system MySQL. [...] These sessions provided a broad, complete overview of where Linux fits into the current computing landscape from the perspective of a VFP developer, where VFP can be used with Linux, and a conceptual plan for how to approach the incorporation of Linux into your day-to-day work. In order for you to be able to work with a Linux back end, you're going to need to know something about how Linux works. The best way involves a two-step process: First, plunk down a Linux workstation on your desk next to your Windows machine and develop some experience with the new OS.Second, once you have a basic level of comfort with Linux, gained through your experience on a workstation, leverage that knowledge and learn to connect to a Linux server from your Windows machine. This track showed both of these processes: What you can expect when you set up your Linux work-station, how to set it up, how to connect to your Windows network, how to fit VFP into the mix, and even how you could use it to replace your Windows workstation in some cases. Also this track demonstrated how to connect to an existing Linux server, running MySQL or an another back end, and how to get your VFP apps talking to that back end data. This track also showed both of the positions you can take. Rainer disliked it wholeheartedly (the bad guy position in these talks) and Jochen loved it (the good guy and "typical Linux techie"-position we all love). These opposite position lasted for three sessions and both sides where shown with their Pros and Cons in live and lively discussions of the speakers (club banging was forbidden). Gerold Luebben showed how Visual Foxpro and MySQL can work together. MySQL is as one the most well known open SOURCE databases for nearly all platforms available. Particularly in eBusiness MySQL is well positioned and well known for its performance and its stability. Still we like Visual FoxPro more - for sure . [...]

• SQL SERVER – Read Only Files and SQL Server Management Studio (SSMS)

  - by pinaldave

  Just like any other Developer or DBA SQL Server Management Studio is my favorite application. Any any moment of the time I have multiple instances of the same application are open and I am working on it. Recently, I have come across a very interesting feature in SSMS related to “Read Only” files. I believe it is a little unknown feature as well so decided to write a blog about the same. First create a read only SQL file. You can make any file read by Right Click >> Properties >> Select Attribute Read Only. Now open the same file in SQL Server Management Studio. You will find that besides the file name there is a small ‘lock’ icon. This small icon indicates that the file is read only. Now let us attempt to edit the read only file. It will let us edit the file any way we want, however when we attempt to save it, it gives following pop-up value. The options in the pop-up are self explanatory and I liked it. The goal of the read only file is to prevent users to make un-intended changes. However, when a user should have complete control over the user file. User should be aware that the file is read only but if he wants to edit the file or save as a new file the choices should be present in front of it and the pop-up menu precisely captures the same. Now let us check option related to this feature in SSMS. Go to Menu >> Options >> Environment >> Documents You will find the third option which is “Allow editing of read-only files; warn when attempt to save”. In the above scenario it was already checked. Let us uncheck the same and do the same exercise which we have done earlier. I closed all the earlier window to avoid confusion. With the new option selected when I attempt to even modify the Read Only file, it gives me totally different pop up screen. It gives me an option like “Edit In-Memory”, “Make Writeable” etc. When you select “Edit In-Memory” it allows you to edit the file and later you can save as new file – just like the earlier scenario which we have discussed. . If clicked on the Make Writeable it will remove the restriction of the Read Only and file can be edited as pleased.

• Fill a Flash Drive with Portable Software using Lupo PenSuite

  - by Asian Angel

  A flash drive full of portable software is helpful to have along wherever you go. The Lupo PenSuite lets you choose from three different versions to get the best fit for your everyday needs. Note: If running the full version you will need a 512 MB USB flash drive or larger. Using Lupo PenSuite The one window to watch for during the setup process is where you have the opportunity to add a specific language pack if needed. Outside of that all that you need to do is sit back and wait for the suite to be extracted. Note: Extraction times will vary based on version and extraction location. Here we browsed to our flash drive to extract it to… Once the setup process is complete locate and double click the Lupo_PenSuite.exe file. This one time window will present you the opportunity to start using the suite immediately, or go directly into the options. When the suite is active you will have a new system tray icon that operates as a start menu button. At the bottom you can monitor the remaining room on your flash drive, and use the close button to exit the suite (may display as a power button based on menu theme). A quick look at the set up inside the suite. There is a pre-configured area for organizing and storing your personal files. Prefer a classic style menu? Just select for it in the options (various tab) and enjoy a smaller streamlined look. Note: You can also change the theme for the regular menu and add a user pic. The suite provides access to your portable software and online sites. You get to enjoy the best of both as shown in the following examples. Websites will open using the suite’s portable Firefox install. VLC is ready to play your downloaded videos. The suite also has some very nice photo editing programs added in. Installing Additional Apps If one of your favorite programs is not included in the suite version, it only takes a few minutes to add it in. Go to the Additional Apps webpage, download the app(s), and extract them onto your hard-drive. Note: Link for additional apps webpage provided below. Add the extracted app(s) to the MyApps folder in the suite’s folder hierarchy. Click on ASuite in the suite’s start menu. Drag and drop the portable app’s exe file into the MyApps section in the ASuite window. Your new software’s shortcut should display as shown here. Close this window when finished. Checking the suite’s start menu will show your new software ready to be used. Conclusion If you need a good portable software collection to carry with you on a flash drive then Lupo PenSuite is definitely worth taking a look at. We tested Lupo PenSuite on XP, Vista, and Windows 7 and it works great on all three. Another popular choice is PortableApps and you can check out our Review of that too they are essentially the same thing, each is just packaged differently.

• FairWarning Privacy Monitoring Solutions Rely on MySQL to Secure Patient Data

  - by Rebecca Hansen

  FairWarning® solutions have audited well over 120 billion events, each of which was processed and stored in a MySQL database. FairWarning is the world's leading supplier of privacy monitoring solutions for electronic health records, relied on by over 1,200 Hospitals and 5,000 Clinics to keep their patients' data safe. In January 2014, FairWarning was awarded the highest commendation in healthcare IT as the first ever Category Leader for Patient Privacy Monitoring in the "2013 Best in KLAS: Software & Services" report[1]. FairWarning has used MySQL as their solutions’ database from their start in 2005 to worldwide expansion and market leadership. FairWarning recently migrated their solutions from MyISAM to InnoDB and updated from MySQL 5.5 to 5.6. Following are some of benefits they’ve had as a result of those changes and reasons for their continued reliance on MySQL (from FairWarning MySQL Case Study). Scalability to Handle Terabytes of Data FairWarning's customers have a lot of data: On average, FairWarning customers receive over 700,000 events to be processed daily. Over 25% of their customers receive over 30 million events per day, which equates to over 1 billion events and nearly one terabyte (TB) of new data each month. Databases range in size from a few hundred GBs to 10+ TBs for enterprise deployments (data are rolled off after 13 months). Low or Zero Admin = Few DBAs "MySQL has not required a lot of administration. After it's been tuned, configured, and optimized for size on initial setup, we have very low administrative costs. I can scale and add more customers without adding DBAs. This has had a big, positive impact on our business.” - Chris Arnold, FairWarning Vice President of Product Management and Engineering. Performance Schema  As the size of FairWarning's customers has increased, so have their tables and data volumes. MySQL 5.6’ new maintenance and management features have helped FairWarning keep up. In particular, MySQL 5.6 performance schema’s low-level metrics have provided critical insight into how the system is performing and why. Support for Mutli-CPU Threads MySQL 5.6' support for multiple concurrent CPU threads, and FairWarning's custom data loader allow multiple files to load into a single table simultaneously vs. one at a time. As a result, their data load time has been reduced by 500%. MySQL Enterprise Hot Backup Because hospitals and clinics never stop, FairWarning solutions can’t either. FairWarning changed from using mysqldump to MySQL Enterprise Hot Backup, which has reduced downtime, restore time, and storage requirements. For many of their larger customers, restore time has decreased by 80%. MySQL Enterprise Edition and Product Roadmap Provide Complete Solution "MySQL's product roadmap fully addresses our needs. We like the fact that MySQL Enterprise Edition has everything included; there's no need to purchase separate modules."  - Chris Arnold Learn More>> FairWarning MySQL Case Study Why MySQL 5.6 is an Even Better Embedded Database for Your Products presentation Updating Your Products to MySQL 5.6, Best Practices for OEMs on-demand webinar (audio and / or slides + Q&A transcript) MyISAM to InnoDB – Why and How on-demand webinar (same stuff) Top 10 Reasons to Use MySQL as an Embedded Database white paper [1] 2013 Best in KLAS: Software & Services report, January, 2014. © 2014 KLAS Enterprises, LLC.

• Fake It Easy On Yourself

  - by Lee Brandt

  I have been using Rhino.Mocks pretty much since I started being a mockist-type tester. I have been very happy with it for the most part, but a year or so ago, I got a glimpse of some tests using Moq. I thought the little bit I saw was very compelling. For a long time, I had been using: 1: var _repository = MockRepository.GenerateMock<IRepository>(); 2: _repository.Expect(repo=>repo.SomeCall()).Return(SomeValue); 3: var _controller = new SomeKindaController(_repository); 4:  5: ... some exercising code 6: _repository.AssertWasCalled(repo => repo.SomeCall()); I was happy with that syntax. I didn’t go looking for something else, but what I saw was: 1: var _repository = new Mock(); And I thought, “That looks really nice!” The code was very expressive and easier to read that the Rhino.Mocks syntax. I have gotten so used to the Rhino.Mocks syntax that it made complete sense to me, but to developers I was mentoring in mocking, it was sometimes to obtuse. SO I thought I would write some tests using Moq as my mocking tool. But I discovered something ugly once I got into it. The way Mocks are created makes Moq very easy to read, but that only gives you a Mock not the object itself, which is what you’ll need to pass to the exercising code. So this is what it ends up looking like: 1: var _repository = new Mock<IRepository>(); 2: _repository.SetUp(repo=>repo.SomeCall).Returns(SomeValue); 3: var _controller = new SomeKindaController(_repository.Object); 4: .. some exercizing code 5: _repository.Verify(repo => repo.SomeCall()); Two things jump out at me: 1) when I set up my mocked calls, do I set it on the Mock or the Mock’s “object”? and 2) What am I verifying on SomeCall? Just that it was called? that it is available to call? Dealing with 2 objects, a “Mock” and an “Object” made me have to consider naming conventions. Should I always call the mock _repositoryMock and the object _repository? So I went back to Rhino.Mocks. It is the most widely used framework, and show other how to use it is easier because there is one natural object to use, the _repository. Then I came across a blog post from Patrik Hägne, and that led me to a post about FakeItEasy. I went to the Google Code site and when I saw the syntax, I got very excited. Then I read the wiki page where Patrik stated why he wrote FakeItEasy, and it mirrored my own experience. So I began to play with it a bit. So far, I am sold. the syntax is VERY easy to read and the fluent interface is super discoverable. It basically looks like this: 1: var _repository = A.Fake<IRepository>(); 2: a.CallTo(repo=>repo.SomeMethod()).Returns(SomeValue); 3: var _controller = new SomeKindaController(_repository); 4: ... some exercising code 5: A.CallTo(() => _repository.SOmeMethod()).MustHaveHappened(); Very nice. But is it mature? It’s only been around a couple of years, so will I be giving up some thing that I use a lot because it hasn’t been implemented yet? I doesn’t seem so. As I read more examples and posts from Patrik, he has some pretty complex scenarios. He even has support for VB.NET! So if you are looking for a mocking framework that looks and feels very natural, try out FakeItEasy!

• Windows Azure Use Case: New Development

  - by BuckWoody

  This is one in a series of posts on when and where to use a distributed architecture design in your organization's computing needs. You can find the main post here: http://blogs.msdn.com/b/buckwoody/archive/2011/01/18/windows-azure-and-sql-azure-use-cases.aspx Description: Computing platforms evolve over time. Originally computers were directed by hardware wiring - that, the “code” was the path of the wiring that directed an electrical signal from one component to another, or in some cases a physical switch controlled the path. From there software was developed, first in a very low machine language, then when compilers were created, computer languages could more closely mimic written statements. These language statements can be compiled into the lower-level machine language still used by computers today. Microprocessors replaced logic circuits, sometimes with fewer instructions (Reduced Instruction Set Computing, RISC) and sometimes with more instructions (Complex Instruction Set Computing, CISC). The reason this history is important is that along each technology advancement, computer code has adapted. Writing software for a RISC architecture is significantly different than developing for a CISC architecture. And moving to a Distributed Architecture like Windows Azure also has specific implementation details that our code must follow. But why make a change? As I’ve described, we need to make the change to our code to follow advances in technology. There’s no point in change for its own sake, but as a new paradigm offers benefits to our users, it’s important for us to leverage those benefits where it makes sense. That’s most often done in new development projects. It’s a far simpler task to take a new project and adapt it to Windows Azure than to try and retrofit older code designed in a previous computing environment. We can still use the same coding languages (.NET, Java, C++) to write code for Windows Azure, but we need to think about the architecture of that code on a new project so that it runs in the most efficient, cost-effective way in a Distributed Architecture. As we receive new requests from the organization for new projects, a distributed architecture paradigm belongs in the decision matrix for the platform target. Implementation: When you are designing new applications for Windows Azure (or any distributed architecture) there are many important details to consider. But at the risk of over-simplification, there are three main concepts to learn and architect within the new code: Stateless Programming - Stateless program is a prime concept within distributed architectures. Rather than each server owning the complete processing cycle, the information from an operation that needs to be retained (the “state”) should be persisted to another location c(like storage) common to all machines involved in the process.  An interesting learning process for Stateless Programming (although not unique to this language type) is to learn Functional Programming. Server-Side Processing - Along with developing using a Stateless Design, the closer you can locate the code processing to the data, the less expensive and faster the code will run. When you control the network layer, this is less important, since you can send vast amounts of data between the server and client, allowing the client to perform processing. In a distributed architecture, you don’t always own the network, so it’s performance is unpredictable. Also, you may not be able to control the platform the user is on (such as a smartphone, PC or tablet), so it’s imperative to deliver only results and graphical elements where possible.  Token-Based Authentication - Also called “Claims-Based Authorization”, this code practice means instead of allowing a user to log on once and then running code in that context, a more granular level of security is used. A “token” or “claim”, often represented as a Certificate, is sent along for a series or even one request. In other words, every call to the code is authenticated against the token, rather than allowing a user free reign within the code call. While this is more work initially, it can bring a greater level of security, and it is far more resilient to disconnections. Resources: See the references of “Nondistributed Deployment” and “Distributed Deployment” at the top of this article for more information with graphics:  http://msdn.microsoft.com/en-us/library/ee658120.aspx  Stack Overflow has a good thread on functional programming: http://stackoverflow.com/questions/844536/advantages-of-stateless-programming  Another good discussion on Stack Overflow on server-side processing is here: http://stackoverflow.com/questions/3064018/client-side-or-server-side-processing Claims Based Authorization is described here: http://msdn.microsoft.com/en-us/magazine/ee335707.aspx

• PASS Summit 2011 &ndash; Part IV

  - by Tara Kizer

  This is the final blog for my PASS Summit 2011 series.  Well okay, a mini-series, I guess. On the last day of the conference, I attended Keith Elmore’ and Boris Baryshnikov’s (both from Microsoft) “Introducing the Microsoft SQL Server Code Named “Denali” Performance Dashboard Reports, Jeremiah Peschka’s (blog|twitter) “Rewrite your T-SQL for Great Good!”, and Kimberly Tripp’s (blog|twitter) “Isolated Disasters in VLDBs”. Keith and Boris talked about the lifecycle of a session, figuring out the running time and the waiting time.  They pointed out the transient nature of the reports.  You could be drilling into it to uncover a problem, but the session may have ended by the time you’ve drilled all of the way down.  Also, the reports are for troubleshooting live problems and not historical ones.  You can use Management Data Warehouse for historical troubleshooting.  The reports provide similar benefits to the Activity Monitor, however Activity Monitor doesn’t provide context sensitive drill through. One thing I learned in Keith’s and Boris’ session was that the buffer cache hit ratio should really never be below 87% due to the read-ahead mechanism in SQL Server.  When a page is read, it will read the entire extent.  So for every page read, you get 7 more read.  If you need any of those 7 extra pages, well they are already in cache.  I had a lot of fun in Jeremiah’s session about refactoring code plus I learned a lot.  His slides were visually presented in a fun way, which just made for a more upbeat presentation.  Jeremiah says that before you start refactoring, you should look at your system.  Investigate missing or too many indexes, out-of-date statistics, and other areas that could be leading to your code running slow.  He talked about code standards.  He suggested using common abbreviations for aliases instead of one-letter aliases.  I’m a big offender of one-letter aliases, but he makes a good point.  He said that join order does not matter to the optimizer, but it does matter to those who have to read your code.  Now let’s get into refactoring! Eliminate useless things – useless/unneeded joins and columns.  If you don’t need it, get rid of it! Instead of using DISTINCT/JOIN, replace with EXISTS Simplify your conditions; use UNION or better yet UNION ALL instead of OR to avoid a scan and use indexes for each union query Branching logic – instead of IF this, IF that, and on and on…use dynamic SQL (sp_executesql, please!) or use a parameterized query in the application Correlated subqueries – YUCK! Replace with a join Eliminate repeated patterns Last, but certainly not least, was Kimberly’s session.  Kimberly is my favorite speaker.  I attended her two-day pre-conference seminar at PASS Summit 2005 as well as a SQL Immersion Event last December.  Did I mention she’s my favorite speaker?  Okay, enough of that. Kimberly’s session was packed with demos.  I had seen some of it in the SQL Immersion Event, but it was very nice to get a refresher on these, especially since I’ve got a VLDB with some growing pains.  One key takeaway from her session is the idea to use a log shipping solution with a load delay, such as 6, 8, or 24 hours behind the primary.  In the case of say an accidentally dropped table in a VLDB, we could retrieve it from the secondary database rather than waiting an eternity for a restore to complete.  Kimberly let us know that in SQL Server 2012 (it finally has a name!), online rebuilds are supported even if there are LOB columns in your table.  This will simplify custom code that intelligently figures out if an online rebuild is possible. There was actually one last time slot for sessions that day, but I had an airplane to catch and my kids to see!

• How to Create and Manage Contact Groups in Outlook 2010

  - by Mysticgeek

  If you find you’re sending emails to the same people all the time during the day, it’s tedious entering in their addresses individually. Today we take a look at creating Contact Groups to make the process a lot easier. Create Contact Groups Open Outlook and click on New Items \ More Items \ Contact Group. This opens the Contract Group window. Give your group a name, click on Add Members, and select the people you want to add from your Outlook Contacts, Address Book, or Create new ones. If you select from your address book you can scroll through and add the contacts you want. If you have a large amount of contacts you might want to search for them or use Advanced Find. If you want to add a new email contact to your group, you’ll just need to enter in their display name and email address then click OK. If you want the new member added to your Contacts list then make sure Add to Contacts is checked. After you have the contacts you want in the group, click Save & Close. Now when you compose a message you should be able to type in the name of the Contact Group you created… If you want to make sure you have everyone included in the group, click on the plus icon to expand the contacts. You will get a dialog box telling you the members of the group will be shown and you cannot collapse it again. Check the box not to see the message again then click OK. Then the members of the group will appear in the To field. Of course you can enter a Contact Group into the CC or Bcc fields as well. Add or Remove Members to a Contact Group After expanding the group you might notice some contacts aren’t included, or there is an old contact you don’t want to be in the group anymore. Click on the To button… Right-click on the Contact Group and select Properties. Now you can go ahead and Add Members… Or highlight a member and remove them…when finished click Save & Close. If you need to send emails to several of the same people, creating Contact Groups is a great way to save time by not entering them individually. If you work in for a large company, creating Contact Groups by department is a must!

• Where is the value of OEA

  - by [email protected]

  In a room full of architects, if you were to ask for the definition of enterprise architecture, or the importance thereof,  you are likely to get a number of varying view points ranging from,  a complete analysis of the digital assets of an organization,  to, a strategic alignment of business goals/objectives to IT initiatives.  Similiarily in a room full of senior business executives,  if you asked them how they see their IT groups and their effectiveness to align to business strategy,  you would get a myriad of responses,  ranging from, “a huge drain on our bottom line”, “always more expensive than budgeted”, “lack of agility,  by the time IT is ready,  my business strategy has changed”, and on the rare occurrence, “ a leader of innovation,  that is lock step with my business strategy”. However does this necessarily demonstrate the overall value of enterprise architecture.  Having a framework, and process is of critical importance to help produce a number of the artefacts that ultimately align technology goals and initiatives to business strategy,  however,  is that really where the value is?  I believe that first we need to understand the concept of value.  Value typically is a measure of sorts,  when we purchase a product it’s value is equivalent to the maximum amount that someone is willing to pay for the product,  however,  is the same equation valid in terms of the business value of enterprise architecture? Is the library of artefacts generated through a process/framework, inclusive of a strategic roadmap to realize the enterprise architecture where the value is? If we agree that enterprise architecture is the alignment of IT and IT assets to support business strategy, and by achieving our business strategy, we have we have increased the business value of the enterprise then;  it seems that, in order to really identify the true value of an enterprise architecture,  we need to understand how we measure business value .  A number of formal measurement methodologies exist for this purpose, business models, balanced scorecards, etc   After we have an understanding on how to measure the business value of each of the organizational units within an enterprise, then we understand how the enterprise architecture contributes to the success of business strategy,  and EXECUTE on the roadmap to implement, and deliver the IT initiatives that provide MEASUREABLE returns, As we analyse the value chain of each of the individual organizational units within the enterprise we may identify how that unit has performed by quantitatively measuring it proximity to achieving the goals defined by the business for each unit. However, It would appear that true business value (the aggregate of all of the business units in the value chain), is to some degree subjectively measured  as for public companies this lies in shareholder value,  as the true value, or be it, the maximum amount that someone would pay for shares of an organization.

• Part 9: EBS Customizations, how to track

  - by volker.eckardt(at)oracle.com

  In the previous blogs we were concentrating on the preparation tasks. We have defined standards, we know about the tools and techniques we will start with. Additionally, we have defined the modification strategy, and how to handle such topics best. Now we are ready to take the requirements! Such requirements coming over in spreadsheets, word files (like GAP documents), or in any other format. As we have to assign some attributes, we start numbering all that and assign a short name to each of these requirements (=CEMLI reference). We may also have already a Functional person assigned, and we might involve someone from the tech team to estimate, and we like to assign a status such as 'planned', 'estimated' etc. All these data are usually kept in spreadsheets, but I would put them into a database (yes, I am from Oracle :). If you don't have any good looking and centralized application already, please give a try with Oracle APEX. It should be up and running in a day and the imported sheets are than manageable concurrently!  For one of my clients I have created this CEMLI-DB; in between enriched with a lot of additional functionality, but initially it was just a simple centralized CEMLI tracking application. Why I am pointing out again the centralized method to manage such data? Well, your data quality will dramatically increase, if you let your project members see (also review and update) "your" data.  APEX allows you to filter, sort, print, and also export. And if you can spend some time to define proper value lists, everyone will gain from. APEX allows you to work in 'agile' mode, means you can improve your application step by step. Let's say you like to reference a document, or even upload the same, you can do that. Or, you need to classify the CEMLIs by release, just add this release field, same for business area or CEMLI type. One CEMLI record may then look like this: Prepare one or two (online) reports, to be ready to present your "workload" to the project management. Use such extracts also when you work offline (to prioritize etc.). But as soon as you are again connected, feed the data back into the central application. Note: I have combined this application with an additional issue tracker.  Here the most important element is the CEMLI reference, which acts as link to any other application (if you are not using APEX also as issue tracker :).  Please spend a minute to define such a reference (see blog Part 8: How to name Customizations).   Summary: Building the bridge from Gap analyse to the development has to be done in a controlled way. Usually the information is provided differently, but it is suggested to collect all requirements centrally. Oracle APEX is a great solution to enter and maintain such information in a structured, but flexible way. APEX helped me a lot to work with distributed development teams during the complete development cycle.

• Installing Eclipse for OSB Development

  - by James Taylor

  OSB provides 2 methods for OSB development, the OSB console, and Eclipse. This post deals with a typical development environment with OSB installed on a remote server and the developer requiring an IDE on their PC for development. As at 11.1.1.4 Eclipse is only IDE supported for OSB development. We are hoping OSB will support JDeveloper in the future. To get the download for Eclipse use the download WebLogic Server with the Oracle Enterprise Pack for Eclipse, e.g. wls1034_oepe111161_win32.exe.To ensure the Eclipse version is compatible with your OSB version I recommend using the Eclipse that comes with the supported WLS server, e.g. OSB 11.1.1.4 you would install WLS 10.3.4+oepe.The install is a 2 step process, install the base Eclipse, then install the OSB plugins. In this example I'm using the 11.1.1.4 install for windows, your versions may differ. You need to download 2 programs, WebLogic Server with the oepe plugin for your OS, and the Oracle Service Bus which is generally generic. Place these files in a directory of your choice. Start the executable I create a new Oracle Home for this installation as it don't want to impact on my JDeveloper install or any other Oracle products installed on my machine. Ignore the support / email notifications Choose a custom install as we only want to install the minimum for Eclipse. If you really want you can do a typical and install everything. Deselect all products then select the Oracle Enterprise Pack for Eclipse. This will select the minimum prerequisites required for install. As I'm only going to use this home for OSB Development I deselect the JRockit JVM. Accept the locations for the installs. If running on a Windows environment you will be asked to start a Node Manger service. This is optional. I have chosen to ignore. Select the user permissions you require, I have set to default. Do a last check to see if the values are correct and continue to install. The install should start. The install should complete successfully. I chose not to run the Quick Start. Extract the OSB download to a location of your choice and double click on the setup.exe. You may be asked to supply a correct java location. Point this to the java installed in your OS. I'm running Windows 7 so I used the 64bit version. Skip the software updates. Set the OSB home to the location of the WLS home installed above Choose a custom install as all we want to install is the OSB Eclipse Plugins. Select OSB IDE. For the rest of the install screens accept the defaults. Start the install There is no need to configure a WLS domain if you only intend to deploy to the remote server. If you need to do this there are other sites how to configure via the configuration wizard. Start Eclipse to make sure the OSB Plugin has been created. In the top right drop down you should see OSB as an option. Connecting to the remote server, select the Server Tab at the bottom Right-click in that frame and select Server. Chose the remote server version and the hostname Provide and name for your server if necessary, and accept the defaults Enter connection details for the remote server Click on the Remote server and it should validate stating its status.Now you ready to develop, Happy developing!

• WebGrid Helper and Complex Types

  - by imran_ku07

      Introduction:           WebGrid helper makes it very easy to show tabular data. It was originally designed for ASP.NET Web Pages(WebMatrix) to display, edit, page and sort tabular data but you can also use this helper in ASP.NET Web Forms and ASP.NET MVC. When using this helper, sometimes you may run into a problem if you use complex types in this helper. In this article, I will show you how you can use complex types in WebGrid helper.       Description:             Let's say you need to show the employee data and you have the following classes,   public class Employee { public string Name { get; set; } public Address Address { get; set; } public List<string> ContactNumbers { get; set; } } public class Address { public string City { get; set; } }               The Employee class contain a Name, an Address and list of ContactNumbers. You may think that you can easily show City in WebGrid using Address.City, but no. The WebGrid helper will throw an exception at runtime if any Address property is null in the Employee list. Also, you cannot directly show ContactNumbers property. The easiest way to show these properties is to add some additional properties,   public Address NotNullableAddress { get { return Address ?? new Address(); } } public string Contacts { get { return string.Join("; ",ContactNumbers); } }               Now you can easily use these properties in WebGrid. Here is the complete code of this example,  @functions{ public class Employee { public Employee(){ ContactNumbers = new List<string>(); } public string Name { get; set; } public Address Address { get; set; } public List<string> ContactNumbers { get; set; } public Address NotNullableAddress { get { return Address ?? new Address(); } } public string Contacts { get { return string.Join("; ",ContactNumbers); } } } public class Address { public string City { get; set; } } } @{ var myClasses = new List<Employee>{ new Employee { Name="A" , Address = new Address{ City="AA" }, ContactNumbers = new List<string>{"021-216452","9231425651"}}, new Employee { Name="C" , Address = new Address{ City="CC" }}, new Employee { Name="D" , ContactNumbers = new List<string>{"045-14512125","21531212121"}} }; var grid = new WebGrid(source: myClasses); } @grid.GetHtml(columns: grid.Columns( grid.Column("NotNullableAddress.City", header: "City"), grid.Column("Name"), grid.Column("Contacts")))                    Summary:           You can use WebGrid helper to show tabular data in ASP.NET MVC, ASP.NET Web Forms and  ASP.NET Web Pages. Using this helper, you can also show complex types in the grid. In this article, I showed you how you use complex types with WebGrid helper. Hopefully you will enjoy this article too.

• Override ToString() in your Classes

  - by psheriff

  One of the reasons I love teaching is because of the questions that I get from attendees. I was giving a presentation at DevConnections and was showing a collection of Product objects. When I hovered over the variable that contained the collection, it looked like Figure 2. As you can see in the collection, I have actual product names of my videos from www.pdsa.com/videos being displayed. To get your data to appear in the data tips you must override the ToString() method in your class. To illustrate this, take the following simple Product class shown below: public class Product{  public string ProductName { get; set; }  public int ProductId { get; set; }} This class does not have an override of the ToString() method so if you create a collection of Product objects you will end up with data tips that look like Figure 1. Below is the code I used to create a collection of Product objects. I have shortened the code in this blog, but you can get the full source code for this sample by following the instructions at the bottom of this blog entry. List<Product> coll = new List<Product>();Product prod; prod = new Product()  { ProductName = "From Zero to HTML 5 in 60 Minutes",     ProductId = 1 };coll.Add(prod);prod = new Product()   { ProductName = "Architecting Applications …",     ProductId = 2 };coll.Add(prod);prod = new Product()  { ProductName = "Introduction to Windows Phone Development",    ProductId = 3 };coll.Add(prod);prod = new Product()   { ProductName = "Architecting a Business  …",     ProductId = 4 };coll.Add(prod);......   Figure 1: Class without overriding ToString() Now, go back to the Product class and add an override of the ToString() method as shown in the code listed below: public class Product{  public string ProductName { get; set; }  public int ProductId { get; set; }   public override string ToString()  {    return ProductName;  }} In this simple sample, I am just returning the ProductName property. However, you can create a whole string of information if you wish to display more data in your data tips. Just concatenate any properties you want from your class and return that string. When you now run the application and hover over the collection object you will now see something that looks like Figure 2. Figure 2: Overriding ToString() in your Class Another place the ToString() override comes in handy is if you forget to use a DisplayMemberPath in your ListBox or ComboBox. The ToString() method is called automatically when a class is bound to a list control. Summary You should always override the ToString() method in your classes as this will help you when debugging your application. Seeing relevant data immediately in the data tip without having to drill down one more layer and maybe scroll through a complete list of properties should help speed up your development process. NOTE: You can download the sample code for this article by visiting my website at http://www.pdsa.com/downloads. Select “Tips & Tricks”, then select “Override ToString” from the drop down list.

• Playing HTML5 Video with fall back for IE8/IE7 and earlier versions of other browsers using Silverlight

  - by Harish Ranganathan

  One of the popular HTML5 tags is the video tag.  The ability to play videos without depending on a plugin is something that excites web developers to a great extent and no wonder you end up seeing video demos in all HTML5 conferences. Now, coming to HTML5 Video, the tag itself is simply <video id=”ID” src=”FILENAME.mp4/ogv/webm” > in the simplest form.  This also means that the video needs to be H.256 encoded MP4 format or some of the other formats as mentioned above.  For a detailed specification on this, check this Wikipedia article HTML5 video is supported by all the modern browsers such as IE9 (currently in RC stage), Mozilla Firefox 4 and Chrome latest versions.  Here below is a simple example of a HTML5 video tag and the screen shot of how it looks like in IE9 RC <!DOCTYPE html> <head></head> <body> <h1>This is a sample of an HTML5 Video</h1> <video src="video.mp4" id="myvideo">Your browser doesn’t support this currently</video> </body> </html> You can add attributes to the video tag such as “autoplay” which will automatically start playing the video.  Also, you can specify “poster” to display an initial picture before the video starts playing etc., but I am not going into those for now. This would play well in the modern browsers as mentioned above.  However, if the end users are viewing this page from an earlier version of browsers such as IE8/IE7 or IE6, this video wouldn’t play.  Whatever text that is specified between the video tags, would just show up. Note: for demo purposes, I went to the IE9 developer toolbar and chose IE8 as Browser Mode to exhibit this legacy behaviour.  However, in the interest of serving the larger community of users who visit the site, we would like to have a fall back mechanism for playing videos on older version of browsers. Now, Silverlight is supported in IE6/7 & 8 and other browsers too.  If we can have the same video encoded for Silverlight, we can put the fall-back code, as follows:- <video src="videos/video.mp4" id="myvideo">     <object height="252" type="application/x-silverlight-2" width="448">         <param name="source" value="resources/player.xap">         <param name="initParams" value="deferredLoad=true, duration=0, m=http://localhost/DemoSite/videos/video.mp4, autostart=false, autohide=true, showembed=true, postid=0" />         <param name="background" value="#00FFFFFF" />     </object> </video>   Note, this sample uses a Silverlight XAP file with the same video and uses the object tag to embed it instead of the HTML5 video tag. So, when I now run this sample and switch to IE8 (using the IE9 Developer toolbar’s Browser Mode), I get and when clicking on the “Play” icon, Note, there are multiple ways to play videos in Silverlight and this is one of the ways.  For a complete list of Silverlight samples, visit http://www.silverlight.net/learn/  Also, we can use Flash to play video in the fall-back mechanism as well. Thus, we can create a fall-back mechanism for playing HTML5 videos for the older browsers and hence ensure that the end users get to experience the same. Cheers !!!

• Entity Framework - Single EMDX Mapping Multiple Database

  - by michaelalisonalviar

  Because of my recent craze on Entity Framework thanks to Sir Humprey, I have continuously searched the Internet for tutorials on how to apply it to our current system. So I've come to learn that with EF, I can eliminate the numerous coding of methods/functions for CRUD operations, my overly used assigning of connection strings, Data Adapters or Data Readers as Entity Framework will map my desired database and will do its magic to create entities for each table I want (using EF Powertool) and does all the methods/functions for my Crud Operations. But as I begin applying it to a new project I was assigned to, I realized our current server is designed to contain each similar entities in different databases. For example Our lookup tables are stored in LookupDb, Accounting-related tables are in AccountingDb, Sales-related tables in SalesDb. My dilemma is I have to use an existing table from LookupDB and use it as a look-up for my new table. Then I have found Miss Rachel's Blog (here)Thank You Miss Rachel!  which enables me to let EF think that my TableLookup1 is in the AccountingDB using the following steps. Im on VS 2010, I am using C# , Using Entity Framework 5, SQL Server 2008 as our DB ServerStep 1:Creating A SQL Synonym. If you want a more detailed discussion on synonyms, this was what i have read -> (link here). To simply put it, A synonym enabled me to simplify my query for the Look-up table when I'm using the AccountingDB fromSELECT [columns] FROM LookupDB.dbo.TableLookup1toSELECT [columns] FROM TableLookup1Syntax: CREATE SYNONYM  TableLookup1(1) FOR LookupDB.dbo.TableLookup1 (2)1. What you want to call the table on your other DB2. DataBaseName.schema.TableNameStep 2: We will now follow Miss Rachel's steps. you can either visit the link on the original topic I posted earlier or just follow the step I made.1. I created a Visual Basic Solution that will contain the 4 projects needed to complete the merging2. First project will contain the edmx file pointing to the AccountingDB3. Second project will contain the edmx file pointing to the LookupDB4. Third Project will will be our repository of the merged edmx file. Create an edmx file pointing To AccountingDB as this the database that we created the Synonym on.Reminder: Aside from using the same name for the Entities, please make sure that you have the same Model Namespace for all your Entities  5. Fourth project that will contain the beautiful EDMX merger that Miss Rachel created that will free you from Hard coding of the merge/recoding the Edmx File of the third project everytime a change is done on either one of the first two projects' Edmx File.6. Run the solution, but make sure that on the solutions properties Single startup project is selected and the project containing the EDMX merger is selected.7. After running the solution, double click on the EDMX file of the 3rd project and set Lazy Loading Enabled = False. This will let you use the tables/entities that you see in that EDMX File.8. Feel free to do your CRUD Operations.I don't know if EF 5 already has a feature to support synonyms as I am still a newbie on that aspect but I have seen a linked where there are supposed suggestions on Entity Framework upgrades and one is the "Support for multiple databases"  So that's it! Thanks for reading!

• Integrating with Fusion Applications using SOAP web services and REST APIs (Part 1 of 2) by Arvind Srinivasamoorthy

  - by JuergenKress

  Fusion Applications provides several types of interfaces to facilitate integration with other applications within the enterprise and on the cloud.As one of the key integration interfaces, Fusion Applications (FA) supports SOAP services based integration, both inbound and outbound. At this point FA doesn’t provide REST API’s but it is planned for a future release. It is however possible to invoke external REST APIs from FA which we will discuss. Oracle continues to invest in improving both SOAP and REST based connectivity. The content in this blog is based on features that were available at the time of writing it. In this two part blog, I will cover the following topics briefly. Invoking FA SOAP web services from external applications Identifying the FA SOAP web service to be invoked Sample invocation from an external application Techniques to invoke FA services from an ADF application Invoking external SOAP Web Services from FA (covered in Part 2) Invoking external REST APIs from FA (covered in Part 2) I’ll touch upon some basics, so that you can quickly build a few SOAP/REST interactions with FA. If you do not already have access to an FA instance (on-premise or SaaS), you can request for a free 30 day trial of the Oracle Sales Cloud using http://cloud.oracle.com 1. Invoking FA SOAP web services from external applications There are two main types of services that FA exposes -  ADF Services - These services allow you to perform CRUD operations on Fusion business objects. For example, Sales Party Service, Opportunity Service etc. Using these services you can typically perform operations such as get, find, create, delete, update etc on FA objects.These services are typically useful for UI driven integrations such as looking up FA information from external application UIs, using third party Interfaces to create/update data in FA. They are also used in non-UI driven integration uses cases such as initial upload of business or setup data, synchronizing data with an external systems, etc. - Composite Services – These services involve more logic than CRUD and often involving human workflows, rules etc. These services perform a business function such as Get Orchestration Order Service and are used when building larger process based integrations with external systems.These services are usually asynchronous in nature and are not typically used for UI integration patterns. 1a. Identifying the FA SOAP web service to be invoked All FA web service metadata is available through an OER instance (Oracle Enterprise Repository) which is publicly available via http://fusionappsoer.oracle.com. This is the starting point for you to discover the services that you are going to work with. You do not need to own a FA account to browse the services using the above UI You can use the search area on the left to narrow down your search to what you are looking for. For example, you can choose the type as by ADF Services or Composite, you can narrow your search to a specific FA version, Product Family etc. Read the complete article here.

• 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.

• Ubuntu 12.04 // Likewise Open // Unable to ever authenticate AD users

  - by Rob

  So Ubuntu 12.04, Likewise latest from the beyondtrust website. Joins domain fine. Gets proper information from lw-get-status. Can use lw-find-user-by-name to retrieve/locate users. Can use lw-enum-users to get all users. Attempting to login with an AD user via SSH generates the following errors in the auth.log file: Nov 28 19:15:45 hostname sshd[2745]: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared object file: No such file or directory Nov 28 19:15:45 hostname sshd[2745]: PAM adding faulty module: pam_winbind.so Nov 28 19:15:51 hostname sshd[2745]: error: PAM: Authentication service cannot retrieve authentication info for DOMAIN\\user.name from remote.hostname Nov 28 19:16:06 hostname sshd[2745]: Connection closed by 10.1.1.84 [preauth] Attempting to login via the LightDM itself generates similar errors in the auth.log file. Nov 28 19:19:29 hostname lightdm: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared object file: No such file or directory Nov 28 19:19:29 hostname lightdm: PAM adding faulty module: pam_winbind.so Nov 28 19:19:47 hostname lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "DOMAIN\user.name" Nov 28 19:19:52 hostname lightdm: [lsass-pam] [module:pam_lsass]pam_sm_authenticate error [login:DOMAIN\user.name][error code:40022] Nov 28 19:19:54 hostname lightdm: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared object file: No such file or directory Nov 28 19:19:54 hostname lightdm: PAM adding faulty module: pam_winbind.so Attempting to login via a console on the system itself generates slightly different errors: Nov 28 19:31:09 hostname login[997]: PAM unable to dlopen(pam_winbind.so): /lib/security/pam_winbind.so: cannot open shared object file: No such file or directory Nov 28 19:31:09 hostname login[997]: PAM adding faulty module: pam_winbind.so Nov 28 19:31:11 hostname login[997]: [lsass-pam] [module:pam_lsass]pam_sm_authenticate error [login:DOMAIN\user.name][error code:40022] Nov 28 19:31:14 hostname login[997]: FAILED LOGIN (1) on '/dev/tty2' FOR 'DOMAIN\user.name', Authentication service cannot retrieve authentication info Nov 28 19:31:31 hostname login[997]: FAILED LOGIN (2) on '/dev/tty2' FOR 'DOMAIN\user.name', Authentication service cannot retrieve authentication info I am baffled. The errors obviously are correct, the file /lib/security/pam_winbind.so does not exist. If its a dependancy/required, surely it should be part of the package? I've installed/reinstalled, I've used the downloaded package from the beyondtrust website, i've used the repository, nothing seems to work, every method of installing this application generates the same errors for me. UPDATE : Hrmm, I thought likewise didn't use native winbind but its own modules. Installing winbind from apt-get uninstalls pbis-open (likewise) and generates failures when installing if pbis-open is installed first. Uninstalled winbind, reinstalled pbis-open, same issue as above. The file pam_winbind.so does not exist in that location. Setting up pbis-open-legacy (7.0.1.918) ... Installing Packages was successful This computer is joined to DOMAIN.LOCAL New libraries and configurations have been installed for PAM and NSS. Clearly it thinks it has installed it, but it hasn't. It may be a legacy issue with the previous attempt to configure domain integration manually with winbind. Does anyone have a working likewise-open installation and does the /etc/nsswitch.conf include references to winbind? Or do the /etc/pam.d/common-account or /etc/pam.d/common-password reference pam_winbind.so? I'm unsure if those entries are just legacy or setup by likewise. UPDATE 2 : Complete reinstall of OS fixed it and it worked seamlessly, like it was meant to and those 2 PAM files did NOT include entries for pam_winbind.so, so that was the underlying problem. Thanks for the assist.
