• Very very slow transfer speeds between Windows 7 and samba server running on Ubuntu 11.10/12.04 minimal

  - by kuzyt

  As mentioned in the title I tried transferring files between Windows 7 and the samba server running on both Ubuntu 11.10 and 12.04 but both showed very slow transfer speeds.

• Where should I start with debugging my exchange server?

  - by joadha

  I'm (foolishly?) attempting to install Exchange on top of Windows Server 2008 (64-bit) over Virtual Box running on Mac OSX Lion. Everything went smoothly until I got to the "Readiness Checks" tab. Readiness failed spectacularly on Hub Transport Role and Mailbox Role prereqs. Before I go too far down the rabbit hole in attempting to remedy this, I was hoping I could get some input on where to start in all of this. I already set up the following Active Directory roles, but it didn't seem to help: Active Directory Domain Services Active Directory Lightweight Directory Services I also enabled an Application Server role. Those three are the only roles I've set up-- I cannot locate within Server Manager the Organization Manager role or any of the other roles referenced in the list of borkedness below. Is this a typical experience in Exchange installation? Is there a tutorial created by somebody outside of Microsoft? Here's the output from Readiness Checks: Summary: 5 item(s). 2 succeeded, 3 failed.

• Ubuntu 11.10 running in windows 7 (wubi) AND on a separate partition

  - by Pareen

  I am in a very strange situation and need some help: I installed Ubuntu 11.10 through Wubi a while back so that I can use it alongside Windows 7. I was running out of space on my disk when trying to install applications. Without understanding how Wubi worked, I partitioned my C drive (creating a new 90 GB partition) in Windows, booted from the Ubuntu 11.10 install/live disk, and used the "something else" option to create a ext4 (setting the mount point to root) and swap space partitions (/sda5 and /sda6). After the install, my computer no longer boots with the previous Wubi menu and is now using the Linux grub. The options I have are /sda2, which boots Windows 7; /sda1, which doesn't do anything and reloads the same menu, and the run Linux options. So I now have Ubuntu running on a separate partition, as well as the original Wubi install. I want to delete the seperate partition and go back to running Ubuntu on Wubi...if I remove the partition will I need the Windows 7 disk to restore the boot loader? I dont have the Windows 7 disk on me so what is the best way to clean this up so I get rid of the seperate partition? -------------------------------------------------UPDATE----------------------------------------------------- ============================================================================================================ thank you so much for your response. Actually, it would be fantastic if I could migrate my Wubi install into the new partition because I had downloaded the AOSP on the Wubi install (as well as other files) and would love to preserve them. If i can do that and work on the new partition with the old files than that would be great, and I can worry about wiping out the partition completely later on i.e. when I have the windows disk or something. Can you tell me how to do this migration?? So when I select the /sda2, it loads up my Windows. If i click on the Linux, it loads up the newly install Linux (my files that were on the Wubi install aren't there) fine. If I click on the /sda1 (SYSTEM_DRIVE... this is what the Wubi was using to boot the menu that let me select Windows 7 or Ubuntu)... it fails and just reloads the original menu. Here is the link to my boot info script http://pastebin.com/dMrY0NL3

• SQLAuthority News – Presented Soft Skill Session on Presentation Skills at SQL Bangalore on May 3, 2014

  - by Pinal Dave

  I have presented on various database technologies for almost 10 years now. SQL, Database and NoSQL have been part of my life. Earlier this month, I had the opportunity to present on the topic Performing an Effective Presentation. I must say it was blast to prepare as well as present this session. This event was part of the SQL Bangalore community. If you are in Bangalore, you must be part of this group. SQL Bangalore is a wonderful community and we always have a great response when we present on technology. It is SQL User Group and we discuss everything SQL there. This month we had SQL Server 2014 theme and we had a community launch of SQL Server. We have the best of the best speakers presenting on SQL Server 2014 technology. The event had amazing speakers and each of them did justice to the subject. You can read about this over here. In this session I told a story from my life. I talked about who inspired me and how I learned to speak in public. I told stories about two legends  who have inspired me. There is no video recording of this session. If you want to get resources from this session, please sign up my newsletter at http://bit.ly/sqllearn. Well, I had a great time at this event. We had over 250 people showed up at this event and had a grand  time together. I personally enjoyed a session of Amit Benerjee, Balmukund Lakhani and Vinod Kumar. Ken and Surabh also entertained the audience. Overall, this was a grand event and if you were in Bangalore and did not make it to this event. You did miss out on a few things.

• Running Apache and Tomcat together on different subdomains?

  - by Ritesh M Nayak

  Posted this on ServerFault but didn't get a response. Hoping I will have better luck on the Ubuntu site. I have been trying to get this working the whole of today. I have a server which resolves to the domain example.com . This is running Apache2 and Tomcat 6. The requirement is to direct requests to example.com to apache2 and app.example.com to Tomcat. I know I have to do a VirtualHost proxy pass for this to work. Here are the settings on my server. /etc/hosts file looks something like this 127.0.0.1 localhost localhost.localdomain example.com app.example.com I have two virtual host files for the different domains in /etc/apache2/sites-enabled /etc/apache2/sites-enabled/example.com looks like this <VirtualHost *:80> # Admin email, Server Name (domain name) and any aliases ServerAdmin webmaster@localhost ServerName example.com ServerAlias www.example.com DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

• 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.

• IE9, HTML5 and truck load of other stuff happening around the web

  - by Harish Ranganathan

  First of all, I haven’t been updating this blog as regularly as it used to be.  Primarily, due to the fact was I was visiting a lot of cities talking about SharePoint, Web Matrix, IE9 and few other stuff.  IE9 is my new found love and I simply think we have done great work in improving the browser and browsing experiences for our users. This post would talk about IE, general things happening around the web and few misconceptions around IE (I had earlier written about IE8 and common myths When you think about the way web has transformed, its truly amazing.  Rewind back to late 90s and early 2000s, web was a luxury.  There were lot of desktop applications running around and web applications was starting to pick up.  Primarily reason was not a lot of folks were into web development and the areas of web were confined to HTML and JavaScript.  CSS was around here and there but no one took it so seriously.  XML, XSLT was fast picking up and contributed to decent web development techniques. So as a web developer all we had to worry about was, building good looking websites which worked well with IE6 and occasionally with Safari.  Firefox was  not even in the picture then and so was Chrome.  But with the various arms of W3C consortium and other bodies working actively on stuff like CSS, SVG and XHTML, few more areas came into picture when it comes to browsers supporting standards.  IE6 for sure wasn’t up to the speed and the main issue we were tackling then was privacy and piracy.  We did invest a lot of our efforts to curb piracy and one of the steps into it was that, IE7 the next version of IE would install only on genuine windows machines.  What this means, is that, people who were running pirated windows xp knowingly/unknowingly could not install IE7 and the limitations of IE6 really hurt them.  One more thing of importance is that, if you were running pirated windows, lots of chances that you didn’t get the security updates and thereby were vulnerable to run viruses/trojans on your system. Many of them actually block using IE in the first place and make it difficult to browse.  SP2 came as a big boon but again was there only for genuine windows machines. With Firefox coming as a free install and also heavily pushed by Google then, it was natural that people would try an alternative.  By then, we had started working on IE8 supporting the best standards (note HTML5, CSS 2.1 and other specs were then work in progress.  they are still) Later, Google in their infinite wisdom realized that with Firefox they were going nowhere and they released Chrome.  Now, they heavily push Chrome even for Firefox users, which is natural since its their browser. In the meanwhile, these browsers push their updates as mandatory and therefore have a very short lifecycle to add enhancements and support for stuff like CSS etc., Meanwhile, when IE8 came out, it really was the best standards supported browser and a lot of people saw our efforts in improving our browser. HTML5 is the buzz word in the industry and there is a lot of noise being made by many browsers claiming their support for it.  IE8 doesn’t have much support for HTML5.  But, with IE9 Beta, we have great support for many of HTML5 specifications.  Note that, HTML5 is still work under progress and one of the board of members working on the spec has mentioned that these specs might change and relying on them heavily is dangerous.  But, some of the advances such as video tag, etc., are indeed supported in IE9 Beta.  IE9 Beta also has full hardware acceleration support which other browsers don’t have. IE8 had advanced security features such as smartscreen filter, in-private browsing, anti-phishing and a lot of other stuff.  IE9 builds on top of these with the best in town security standards as well as support for HTML5, CSS3, Hardware acceleration, SVG and many other advancements in browser.  Read more at http://www.beautyoftheweb.com/#/highlights/html5  To summarize, IE9 Beta is really innovative and you should try it to believe what it provides.  You can visit http://www.beautyoftheweb.com/  to install as well as read more on this.

• T-SQL in Chicago – the LobsterPot teams with DataEducation

  - by Rob Farley

  In May, I’ll be in the US. I have board meetings for PASS at the SQLRally event in Dallas, and then I’m going to be spending a bit of time in Chicago. The big news is that while I’m in Chicago (May 14-16), I’m going to teach my “Advanced T-SQL Querying and Reporting: Building Effectiveness” course. This is a course that I’ve been teaching since the 2005 days, and have modified over time for 2008 and 2012. It’s very much my most popular course, and I love teaching it. Let me tell you why. For years, I wrote queries and thought I was good at it. I was a developer. I’d written a lot of C (and other, more fun languages like Prolog and Lisp) at university, and then got into the ‘real world’ and coded in VB, PL/SQL, and so on through to C#, and saw SQL (whichever database system it was) as just a way of getting the data back. I could write a query to return just about whatever data I wanted, and that was good. I was better at it than the people around me, and that helped. (It didn’t help my progression into management, then it just became a frustration, but for the most part, it was good to know that I was good at this particular thing.) But then I discovered the other side of querying – the execution plan. I started to learn about the translation from what I’d written into the plan, and this impacted my query-writing significantly. I look back at the queries I wrote before I understood this, and shudder. I wrote queries that were correct, but often a long way from effective. I’d done query tuning, but had largely done it without considering the plan, just inferring what indexes would help. This is not a performance-tuning course. It’s focused on the T-SQL that you read and write. But performance is a significant and recurring theme. Effective T-SQL has to be about performance – it’s the biggest way that a query becomes effective. There are other aspects too though – such as using constructs better. For example – I can write code that modifies data nicely, but if I haven’t learned about the MERGE statement and the way that it can impact things, I’m missing a few tricks. If you’re going to do this course, a good place to be is the situation I was in a few years before I wrote this course. You’re probably comfortable with writing T-SQL queries. You know how to make a SELECT statement do what you need it to, but feel there has to be a better way. You can write JOINs easily, and understand how to use LEFT JOIN to make sure you don’t filter out rows from the first table, but you’re coding blind. The first module I cover is on Query Execution. Take a look at the Course Outline at Data Education’s website. The first part of the first module is on the components of a SELECT statement (where I make you think harder about GROUP BY than you probably have before), but then we jump straight into Execution Plans. Some stuff on indexes is in there too, as is simplification and SARGability. Some of this is stuff that you may have heard me present on at conferences, but here you have me for three days straight. I’m sure you can imagine that we revisit these topics throughout the rest of the course as well, and you’d be right. In the second and third modules we look at a bunch of other aspects, including some of the T-SQL constructs that lots of people don’t know, and various other things that can help your T-SQL be, well, more effective. I’ve had quite a lot of people do this course and be itching to get back to work even on the first day. That’s not a comment about the jokes I tell, but because people want to look at the queries they run. LobsterPot Solutions is thrilled to be partnering with Data Education to bring this training to Chicago. Visit their website to register for the course. @rob_farley

• SQL Contests – Solution – Identify the Database Celebrity

  - by Pinal Dave

  Last week we were running contest Identify the Database Celebrity and we had received a fantastic response to the contest. Thank you to the kind folks at NuoDB as they had offered two USD 100 Amazon Gift Cards to the winners of the contest. We had also additional contest that users have to download and install NuoDB and identified the sample database. You can read about the contest over here. Here is the answer to the questions which we had asked earlier in the contest. Part 1: Identify Database Celebrity Personality 1 – Edgar Frank “Ted” Codd (August 19, 1923 – April 18, 2003) was an English computer scientist who, while working for IBM, invented the relational model for database management, the theoretical basis for relational databases. He made other valuable contributions to computer science, but the relational model, a very influential general theory of data management, remains his most mentioned achievement. (Wki) Personality 2 – James Nicholas “Jim” Gray (born January 12, 1944; lost at sea January 28, 2007; declared deceased May 16, 2012) was an American computer scientist who received the Turing Award in 1998 “for seminal contributions to database and transaction processing research and technical leadership in system implementation.” (Wiki) Personality 3 – Jim Starkey (born January 6, 1949 in Illinois) is a database architect responsible for developing InterBase, the first relational database to support multi-versioning, the blob column type, type event alerts, arrays and triggers. Starkey is the founder of several companies, including the web application development and database tool company Netfrastructure and NuoDB. (Wiki) Part 2: Identify NuoDB Samples Database Names In this part of the contest one has to Download NuoDB and install the sample database Hockey. Hockey is sample database and contains few tables. Users have to install sample database and inform the name of the sample databases. Here is the valid answer. HOCKEY PLAYERS SCORING TEAM Once again, it was indeed fun to run this contest. I have received great feedback about it and lots of people wants me to run similar contest in future. I promise to run similar interesting contests in the near future. Winners Within next two days, we will let winners send emails. Winners will have to confirm their email address and NuoDB team will send them directly Amazon Cards. Once again it was indeed fun to run this contest. Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL

• The Windows 8 and Ubuntu 12.04 Dual Boot NIghtmare

  - by Steve

  I have done some research as to how to go about this dual-boot, and I am close, but I need some guidance with booting into Windows 8 (Ubuntu is installed). I have a Lenovo Ideapad y510p. I will go over what I have done to dual-boot this laptop, with windows 8 pre-installed, with Ubuntu 12.04: I followed every instruction to the letter for the 97-vote response here, and everything worked fine up until after the repair boot section: Installing on a Pre-Installed Windows 8 System (UEFI Supported) I ran into the following error upon restarting after the repair boot section: error: invalid arch independent elf magic. This error (a grub issue) disabled me from booting into Ubuntu :( After a little googling, I followed the instructions in the reactivating grub 2 section to resolve the error: http://kb.acronis.com/content/1686 I found a possible solution to fixing the Windows 8 boot issue, and tried it: http://webcache.googleusercontent.com/search?q=cache:i9JMyXzzRpYJ:askubuntu.com/questions/279275/dual-boot-problem-windows-8-ubuntu-12-04+&cd=1&hl=en&ct=clnk&gl=us&client=ubuntu I thought the above solution worked, but when I attempt to boot into Windows 8, I get the following missing file error: File: \Boot\BCD Status: 0xc000000e Info: The Boot Configuration Data for your PC is missing or contains errors. Here is some other information that may be useful: I have 3 partitions devoted to Ubuntu. The first, sda8, has a flag bios_grub (1049 kb). The second, sda9, is where everything else is (96.6 GB). The last, sda10, is for swap (8299 MB). My question is: How do I fix the boot configuration for Windows 8? Any help would be greatly appreciated :) Update 1: When I attempt to boot into UEFI mode, I get the following error: invalid arch independent elf magic (the same error I saw in step 2). Update 2: A useful link here I found: Dual booting Ubuntu 12.04: UEFI and Legacy So, this is my 4th time installing Ubuntu on the laptop, and it looks like I need to install it in UEFI mode. Should I scrap it all again, and reinstall? Or is there ANY way of salvaging my installation? At this point, I can't even boot into Windows (although I have an installation cd to fix the windows boot issue, that would ultimately screw over ubuntu). Update 3: After doing a little more browsing around, I found a cool way around this messy grub stuff, using rEFInd. Rod Smith's post here saved me! Installing ubuntu 12.04.02 in uefi mode Now, I am able to dual-boot Windows 8 and Ubuntu and boot into both operating systems :) I have another issue (relating to the boot configuration in the bios) that I will post as a separate question :)

• How to implement an email unsubscribe system for a site with many kinds of emails?

  - by Mike Liu

  I'm working on a website that features many different types of emails. Users have accounts, and when logged in they have access to a setting page that they can use to customize what types of emails they receive. However, I'd like to also give users an easy way to unsubscribe directly in the emails they receive. I've looked into list unsubscribe headers as well as creating some type of one click link that would unsubscribe a user from that type of email without requiring login or further action. The later would probably require me to break convention and make changes to the database in response to a GET on the link. However, am I incorrect in thinking that either of these would require me to generate and permanently store a unique identifier in my database for every email I ever send, really complicating email delivery? Without that, I'm not sure how I would be able to uniquely identify a user and a type of email in order to change their email preferences, and this identifier would need to be stored forever as a user could have an email sitting in their inbox for a long time before they decide to act on it. Alternatively, I was considering having a no-login page for managing email preferences. In contrast to above where I would need one of these identifiers for each email, this would only need one identifier per user, with no generation or other action required on sending an email. All of these raise security issues, and they could potentially be used by people to tamper with others' email preferences. This could be mitigated somewhat by ensuring that the identifier is really difficult to guess. For the once per user identifier approach, I was considering generating the identifier by passing a user's ID through some type of encryption algorithm, is this a sound approach? For the per-email identifiers, perhaps I could use a user's ID appended to the time. However, even this would not eliminate the problem entirely, as this would really just be security through obscurity, and anyone with the URL could tamper, and in the end the main defense would have to be that most people aren't so bored as to tamper with other people's email preferences. Are there any other alternatives I've missed, or issues or solutions with these that anyone can provide insight on? What are best practices in this area?

• Data Connection Library in SharePoint Server 2010

  - by Wayne

  What is a Data Connection Library in SharePoint Server 2010? A Data Connection Library in Microsoft SharePoint Server 2010 is a library that can contain two kinds of data connections: an Office Data Connection (ODC) file or a Universal Data Connection (UDC) file. Microsoft InfoPath 2010 uses data connections that comply with the Universal Data Connection (UDC) file schema and typically have either a *.udcx or *.xml file name extension. Data sources described by these data connections are stored on the server and can be used in standard form templates and browser-enabled form templates. How to create a SharePoint Server Data Connection Library? 1. Browse to a SharePoint Server 2010 site on which you have at least Design permissions. If you are on the root site, create a new site before you continue with the next step. 2. On the Site Actions menu, click More Options. 3. On the Create page, click Library under Filter By, and then click Data Connection Library. 4. On the right side of the Create page, type a name for the library, and then click the Create button. 5. Copy the URL of the new data connection library. How to create a new data connection file in InfoPath? 1. Open InfoPath Designer 2010, click Blank Form, and then click Design Form. 2. On the Data tab, click Data Connections, and then click Add. 3. In the Data Connection Wizard, click Create a new connection to, click Receive data, and then click Next. 4. Click the kind of data source that you are connecting to, such as Database, Web service, or SharePoint library or list, and then click Next. 5. Complete the remaining steps in the Data Connection Wizard to configure your data connection, and then click Finish to return to the Data Connections dialog box. 6. In the Data Connections dialog box, click Convert to Connection File. 7. In the Convert Data Connection dialog box, enter the URL of the data connection library that you previously copied (delete "Forms/AllItems.aspx" and anything following it from the URL), enter a name for the data connection file at the end of the URL, and then click OK. It will take a few moments to convert and save the data connection file to the library. 8. Confirm that the data connection was converted successfully by examining the Details section of the Data Connections dialog box while the name of the converted data connection is selected. 9. Browse to the SharePoint data connection library, click the drop-down next to the name of the data connection, click Approve/Reject, click Approved, and then click OK. Take advantage of SharePoint Data Connection Library and other useful features of SharePoint family of products that include, SharePoint Foundation 2010, MOSS 2007 and free SharePoint templates or web parts.

• SQL SERVER – How to Roll Back SQL Server Database Changes

  - by Pinal Dave

  In a perfect scenario, no unexpected and unplanned changes occur. There are no unpleasant surprises, no inadvertent changes. However, even with all precautions and testing, there is sometimes a need to revert a structure or data change. One of the methods that can be used in this situation is to use an older database backup that has the records or database object structure you want to revert to. For this method, you have to have the adequate full database backup and a tool that will help you with comparison and synchronization is preferred. In this article, we will focus on another method: rolling back the changes. This can be done by using: An option in SQL Server Management Studio T-SQL, or ApexSQL Log The first two solutions have been described in this article The disadvantages of these methods are that you have to know when exactly the change you want to revert happened and that all transactions on the database executed in a specific time range are rolled back – the ones you want to undo and the ones you don’t. How to easily roll back SQL Server database changes using ApexSQL Log? The biggest challenge is to roll back just specific changes, not all changes that happened in a specific time range. While SQL Server Management Studio option and T-SQL read and roll forward all transactions in the transaction log files, I will show you a solution that finds and scripts only the specific changes that match your criteria. Therefore, you don’t need to worry about all other database changes that you don’t want to roll back. ApexSQL Log is a SQL Server disaster recovery tool that reads transaction logs and provides a wide range of filters that enable you to easily rollback only specific data changes. First, connect to the online database where you want to roll back the changes. Once you select the database, ApexSQL Log will show its recovery model. Note that changes can be rolled back even for a database in the Simple recovery model, when no database and transaction log backups are available. However, ApexSQL Log achieves best results when the database is in the Full recovery model and you have a chain of subsequent transaction log backups, back to the moment when the change occurred. In this example, we will use only the online transaction log. In the next step, use filters to read only the transactions that happened in a specific time range. To remove noise, it’s recommended to use as many filters as possible. Besides filtering by the time of the transaction, ApexSQL Log can filter by the operation type: Table name: As well as transaction state (committed, aborted, running, and unknown), name of the user who committed the change, specific field values, server process IDs, and transaction description. You can select only the tables affected by the changes you want to roll back. However, if you’re not certain which tables were affected, you can leave them all selected and once the results are shown in the main grid, analyze them to find the ones you to roll back. When you set the filters, you can select how to present the results. ApexSQL Log can automatically create undo or redo scripts, export the transactions into an XML, HTML, CSV, SQL, or SQL Bulk file, and create a batch file that you can use for unattended transaction log reading. In this example, I will open the results in the grid, as I want to analyze them before rolling back the transactions. The results contain information about the transaction, as well as who and when made it. For UPDATEs, ApexSQL Log shows both old and new values, so you can easily see what has happened. To create an UNDO script that rolls back the changes, select the transactions you want to roll back and click Create undo script in the menu. For the DELETE statement selected in the screenshot above, the undo script is: INSERT INTO [Sales].[PersonCreditCard] ([BusinessEntityID], [CreditCardID], [ModifiedDate]) VALUES (297, 8010, '20050901 00:00:00.000') When it comes to rolling back database changes, ApexSQL Log has a big advantage, as it rolls back only specific transactions, while leaving all other transactions that occurred at the same time range intact. That makes ApexSQL Log a good solution for rolling back inadvertent data and schema changes on your SQL Server databases.

• Transparent Technology from Amazon

  - by David Dorf

  Amazon has been making some interesting moves again, this time in the augmented humanity area.  Augmented humanity is about helping humans overcome their shortcomings using technology.  Putting a powerful smartphone in your pocket helps you in many ways like navigating streets, communicating with far off friends, and accessing information.  But the interface for smartphones is somewhat limiting and unnatural, so companies have been looking for ways to make the technology more transparent and therefore easier to use. When Apple helped us drop the stylus, we took a giant leap forward in simplicity.  Using touchscreens with intuitive gestures was part of the iPhone's original appeal.  People don't want to know that technology is there -- they just want the benefits.  So what's the next leap beyond the touchscreen to make smartphones even easier to use? Two natural ways we interact with the world around us is by using sight and voice.  Google and Apple have been using both in their mobile platforms for limited uses cases.  Nobody actually wants to type a text message, so why not just speak it?  Any if you want more information about a book, why not just snap a picture of the cover?  That's much more accurate than trying to key the title and/or author. So what's Amazon been doing?  First, Amazon released a new iPhone app called Flow that allows iPhone users to see information about products in context.  Yes, its an augmented reality app that uses the phone's camera to view products, and overlays data about the products on the screen.  For the most part it requires the barcode to be visible to correctly identify the product, but I believe it can also recognize certain logos as well.  Download the app and try it out but don't expect perfection.  Its good enough to demonstrate the concept, but its far from accurate enough.  (MobileBeat did a pretty good review.)  Extrapolate to the future and we might just have a heads-up display in our eyeglasses. The second interesting area is voice response, for which Siri is getting lots of attention.  Amazon may have purchased a voice recognition company called Yap, although the deal is not confirmed.  But it would make perfect sense, especially with the Kindle Fire in Amazon's lineup. I believe over the next 3-5 years the way in which we interact with smartphones will mature, and they will become more transparent yet more important to our daily lives.  This will, of course, impact the way we shop, making information more readily accessible than it already is.  Amazon seems to be positioning itself to be at the forefront of this trend, so we should be watching them carefully.

• SQL – Business Intelligence: Derive Data or Information?

  - by Pinal Dave

  We all know the value of information in our lives. Whether it’s a personal decision or a business initiated one, people need it. But the question is: who is to make the distinction between data and information? We all come across a whole lot of data daily, that may be significant or not. We filter what’s required and forget about the rest. Information is filtered and distilled data. Filtering and distillation can also alter its actual meaning and natural state. Therefore, in this blog we discover some ways to ensure that we’re using business intelligence derived from the right information for making critical management decisions. Four key questions managers must ask themselves before making a decision: 1. Am I working with data or information? 2. What is it’s context? 3. How recent is it? 4. How was it derived or what is the source? The first question is probably the most important. You must know what you’re dealing with here. If you see use of adjectives and conclusions drawn, it’s information. Not raw data. You very next concern must be whether this is guised to present a particular viewpoint or perspective. It makes a lot of difference if you take a decision based on someone’s propaganda to distort real facts. Therefore, the context and the intentions of the distillation process must be clear to you. The next consideration is whether data is recent enough to hold any value. Since it has a very short shelf life, you must ensure that its context and value is not lost out of time. The last and the most important consideration is how was it derived in the first place. The observer effect is what calls the shots here. The source can change the context to a great extent if the collection methodology  and purpose is not clear. Gathering intelligence for decision making requires users to be keen observers and not take the information provided on its face value alone. These probing questions will allow you to make sure that you’re working with clean and accurate data devoid of any influence or manipulations. Only then can you be sure of deriving true business intelligence for your organization. BI technology is also a great way to ensure accuracy of reports. SQL BI Platform  provides advanced tools and techniques for all your BI needs and concerns. Koenig Solutions offers this course along with a host of other Business Intelligence and IT courses on all latest technologies available in the market today.

• Extending the ADF Controller exception handler

  - by frank.nimphius

  The Oracle ADF controller provides a declarative option for developers to define a view activity, method activity or router activity to handle exceptions in bounded or unbounded task flows. Exception handling however is for exceptions only and not handling all types of Throwable. Furthermore, exceptions that occur during the JSF RENDER RESPONSE phase are not looked at either as it is considered too late in the cycle. For developers to try themselves to handle unhandled exceptions in ADF Controller, it is possible to extend the default exception handling, while still leveraging the declarative configuration. To add your own exception handler: · Create a Java class that extends ExceptionHandler · Create a textfile with the name “oracle.adf.view.rich.context.Exceptionhandler” (without the quotes) and store it in .adf\META-INF\services (you need to create the “services” folder) · In the file, add the absolute name of your custom exception handler class (package name and class name without the “.class” extension) For any exception you don't handle in your custom exception handler, just re-throw it for the default handler to give it a try … import oracle.adf.view.rich.context.ExceptionHandler; public class MyCustomExceptionHandler extends ExceptionHandler { public MyCustomExceptionHandler() {      super(); } public void handleException(FacesContext facesContext,                              Throwable throwable, PhaseId phaseId)                              throws Throwable {    String error_message;    error_message = throwable.getMessage();    //check error message and handle it if you can    if( … ){          //handle exception        …    }    else{       //delegate to the default ADFc exception handler        throw throwable;}    } } Note however, that it is recommended to first try and handle exceptions with the ADF Controller default exception handling mechanism. In the past, I've seen attempts on OTN to handle regular application use cases with custom exception handlers for where there was no need to override the exception handler. So don't go for this solution to quickly and always think of alternative solutions. Sometimes a try-catch-final block does it better than sophisticated web exception handling.

• SQLAuthority News – Presenting at Great Indian Developer Summit 2012 – SQL Server Misconception and Resolutions

  - by pinaldave

  Earlier during TechEd 2012, I presented a session on SQL Server Misconception and Resolutions. It was a pleasure to present this session with Vinod Kumar during the event. Great Indian Developer Summit is around the corner and I will be presenting there once again with the same topic. We had an excellent response during the last event; the hall was so filled, but there were plenty who were not able to get into the session as there was no place for them to sit or stand inside. Well, here is another chance for all who missed the presentation. New Additions During the last session, we were a two-presenter tag team, and we presented the session in a sense that it would suit two speakers in one stage. But this time, I am the only presenter, so I decided to present this session in a much different way. I will still assume there are two presenters. One of the presenters will be me, of course, and the second person will be YOU! Yes, you read that right – you will be presenting this session with me. If you wonder how, well, you will have to attend the session to figure it out. Talking Points We will be talking about the following topics in the session which we will relate to SQL Server: Moon Landing Napoléon Bonaparte Wall of China Bollywood …and of course, SQL Server itself. I promise that this 45 minute- presentation will be the one of the highlights of the event for you. Goodies I can only promise 20 goodies as of the moment. I might bring more when you meet me there. Session Details Title: SQL Server Misconceptions and Resolution – A Practical Perspective (Add to Calendar) Abstract: “The earth is flat”! – An ancient common misconception, which has been proven incorrect as we progressed in modern times. In this session, we will see various database misconceptions prevailing and their resolutions with the aid of the demos. In this unique session, the audience will be a part of the conversation and resolution. Date and Time: April 17, 2012, 16:55 to 17:40 Location: J. N.

• AdventureWorks 2014 Sample Databases Are Now Available

  - by aspiringgeek

    Where in the World is AdventureWorks? Recently, SQL Community feedback from twitter prompted me to look in vain for SQL Server 2014 versions of the AdventureWorks sample databases we’ve all grown to know & love. I searched Codeplex, then used the bing & even the google in an effort to locate them, yet all I could find were samples on different sites highlighting specific technologies, an incomplete collection inconsistent with the experience we users had learned to expect.  I began pinging internally & learned that an update to AdventureWorks wasn’t even on the road map.  Fortunately, SQL Marketing manager Luis Daniel Soto Maldonado (t) lent a sympathetic ear & got the update ball rolling; his direct report Darmodi Komo recently announced the release of the shiny new sample databases for OLTP, DW, Tabular, and Multidimensional models to supplement the extant In-Memory OLTP sample DB.  What Success Looks Like In my correspondence with the team, here’s how I defined success: 1. Sample AdventureWorks DBs hosted on Codeplex showcasing SQL Server 2014’s latest-&-greatest features, including:  In-Memory OLTP (aka Hekaton) Clustered Columnstore Online Operations Resource Governor IO 2. Where it makes sense to do so, consolidate the DBs (e.g., showcasing Columnstore likely involves a separate DW DB) 3. Documentation to support experimenting with these features As Microsoft Senior SDE Bonnie Feinberg (b) stated, “I think it would be great to see an AdventureWorks for SQL 2014.  It would be super helpful for third-party book authors and trainers.  It also provides a common way to share examples in blog posts and forum discussions, for example.”  Exactly.  We’ve established a rich & robust tradition of sample databases on Codeplex.  This is what our community & our customers expect.  The prompt response achieves what we all aim to do, i.e., manifests the Service Design Engineering mantra of “delighting the customer”.  Kudos to Luis’s team in SQL Server Marketing & Kevin Liu’s team in SQL Server Engineering for doing so.

• The Social Business Thought Leaders - Ray Wang

  - by kellsey.ruppel

  It seems both consumers and businesses are at the peak of the social hype. Overwhelmed by social media channels, platforms, and processes both in their private and professional life, many early adopters are starting to feel the social fatigue. Mirroring what happened with email and web sites during the late 1990's - early 2000's, more and more managers are looking to move from ubiquitous social media tactics to the most appropriate business use case and processes. This step becomes even more important considering the year over year contraction in IT budgets and the consequent need to maximize return on every dollar spent in new technologies. Ray Wang, CEO and Principal Analyst at Constellation Research, suggests engagement through collaborative technologies both as a conceptual model and a transformational tool for enterprises to reap business value. Without participation - the reasoning goes - there is no value and good technology alone is not enough to guarantee employee and customer adoption. Enterprise gamification is a new lever to succeed with Social Business by directing a critical mass of participation towards desired outcomes. What kind of outcomes? A recent study from Constellation Research (see 2012 Q1 Gamification Early Adopters Best Practices) highlights how Marketing, Customer Service and HR are leading the pack with gamification in processes such as: Sustaining long term customer loyalty (76.4%) Improving response in campaign to lead (74.5%) Right channeling incidents for resolution in social media (67.3%) Growing the number service and support incidents resolved by the community (63.6%) Improving employee referral rates and effective recruiting (43.6%) Driving on-boarding success with new hires (20%) More than simply adding badges, points and leaderboards to existing processes, enterprise gamification should be holistically embedded into employee and customer experience to stimulate specific behaviors. According to Ray Wang this can be done at three core levels: Measurable actions. The behaviors we want to facilitate consist of granular actions (i.e likes, comments, posts, recommendations, etc) and more complex actions (i.e projects, initiatives, programmes) attributed to individuals, groups and/or external actors  Reputation. The reputation an individual has earned through his actions is a key factor in building motivation among others and it is determined by its identity, social standing status and competitiveness Incentives or the intrinsic and extrinsic rewards that motivate behaviors and drive actions Listen to Ray Wang's video-interview to learn more about the dynamics that are shaping the future of collaboration and how gamification can help organizations attain new levels of engagement.

• BizTalk 2009 - The Community ODBC Adapter: Schema Generation with Input Parameters

  - by Stuart Brierley

  As previsouly noted in my post on Schema Generation using the Community ODBC Adapter, I ran into a problem when trying to generate a schema to represent a MySQL stored procedure that had input parameters.  After a bit of investigation and a few deadends I managed to figure out a way around this issue - detailed below are both the problem and solution in case you ever run into this yourself. The Problem Imagine a stored procedure that is coded as follows in MySQL: StuTest(in DStr varchar(80)) BEGIN   Declare GRNID int;   Select grn_id into GRNID from grn_header where distribution_number = DStr;   Select GRNID; END This is quite a simple stored procedure but can be used to illustrate the issue with parameters quite niceley. When generating the schema using the Add Generated Items wizard, I tried selecting "Stored Procedure" and then in the Statement Information window typing the stored procedure name: StuTest Pressing generate then gives the following error: "Incorrect Number of arguments for Procedure StuTest; expected 1, got 0" If you attempt to supply a value for the parameter you end up with a schema that will only ever supply the parameter value that you specify.  For example supplying StuTest('123') will always call the procedure with a parameter value of 123. The Solution   I tried contacting Two Connect about this, but their experience of testing the adapter with MySQL was limited. After looking through the code for the ODBC adapter myself and trying a few things out, I was eventually able to use the ODBC adapter to call a test stored procedure using a two way send port. In the generate schema wizard instead of selecting Stored Procedure I had to choose SQL Script instead, detailing the following script: Call StuTest(@InputParameter) By default this would create a request schema with an attribute called InputParameter, with a SQL type of NVarChar(1).  In most cases this is not going to be correct for the stored procedure being called. To change the type from the default that is applied you need to select the "Override default query processing" check box when specifying the script in the wizard.  This then opens the BizTalk ODBC Override window which lets you change the properties of the parameters and also test out the query script.  Once I had done this I was then able to generate the correct schema, which included an attribute representing the parameter.  By deploying the schema assembly I was then able to try the ODBC adapter out on a two way send port. When supplied with an appropriate message instance (for the generated request schema) this send port successfully returned the expected response.

• Keybindings for individual letter keys (not modifier-combinations) on a GtkTextView widget (Gtk3 and PyGI)

  - by monotasker

  I've been able to set several keybord shortcuts for a GtkTextView and a GtkTextEntry using the new css provider system. I'm finding, though, that I only seem to be able to establish keybindings for combinations including a modifier key. The widget doesn't respond to any bindings I set up that use: the delete key the escape key individual letter or punctuation keys alone Here's the code where I set up the css provider for the keybindings: #set up style context keys = Gtk.CssProvider() keys.load_from_path(os.path.join(data_path, 'keybindings.css')) #set up style contexts and css providers widgets = {'window': self.window, 'vbox': self.vbox, 'toolbar': self.toolbar, 'search_entry': self.search_entry, 'paned': self.paned, 'notelist_treeview': self.notelist_treeview, 'notelist_window': self.notelist_window, 'notetext_window': self.notetext_window, 'editor': self.editor, 'statusbar': self.statusbar } for l, w in widgets.iteritems(): w.get_style_context().add_provider(keys, Gtk.STYLE_PROVIDER_PRIORITY_USER) Then in keybindings.css this is an example of what works: @binding-set gtk-vi-text-view { bind "<ctrl>b" { "move-cursor" (display-lines, -5, 0) }; /* 5 lines up */ bind "<ctrl>k" { "move-cursor" (display-lines, -1, 0) }; /* down */ bind "<ctrl>j" { "move-cursor" (display-lines, 1, 0) }; /* up */ } Part of what I'm trying to do is just add proper delete-key function to the text widgets (right now the delete key does nothing at all). So if I add a binding like one of these, nothing happens: bind "Delete" { "delete-selection" () }; bind "Delete" { "delete-from-cursor" (chars, 1) }; The other part of what I want to do is more elaborate. I want to set up something like Vim's command and visual modes. So at the moment I'm just playing around with (a) setting the widget to editable=false by hitting the esc key; and (b) using homerow letters to move the cursor (as a proof-of-concept exercise). So far there's no response from the escape key or from the letter keys, even though the bindings work when I apply them to modifier-key combinations. For example, I do this in the css for the text-widget: bind "j" { "move-cursor" (display-lines, 1, 0) }; /* down */ bind "k" { "move-cursor" (display-lines, -1, 0) }; /* up */ bind "l" { "move-cursor" (logical-positions, 1, 0) }; /* right */ bind "h" { "move-cursor" (logical-positions, -1, 0) }; /* left */ but none of these bindings does anything, even if other bindings in the same set are respected. What's especially odd is that the vim-like movement bindings above are respected when I attach them to a GtkTreeView widget for navigating the tree-view options: @binding-set gtk-vi-tree-view { bind "j" { "move-cursor" (display-lines, 1) }; /* selection down */ bind "k" { "move-cursor" (display-lines, -1) }; /* selection up */ } So it seems like there are limitations or overrides of some kind on keybindings for the TextView widget (and for the del key?), but I can't find documentation of anything like that. Are these just things that can't be done with the css providers? If so, what are my alternatives for non-modified keybindings? Thanks.

• Most Unprofessional Workplace

  - by TehGrumpyCoder

  I've worked lots of places in lots of roles: Delivery truck driver, Boilermaker, antenna rigger, Professional Musician, Electronic Technician, Electrical Engineer, and for most of my career: Software Turkey. I want to say this large company is the most unprofessional place I've ever worked, but then I think about other jobs such as TTI that stiffed us all for 10 months salary -- or had us work 2-1/2 years at 66% however you want to look at it, or maybe NeoPlanet with a cast from a bad sitcom running the show, I could go on, but I digress (as usual). So maybe this place isn't the *most* unprofessional, but the personnel rank up there. I'm in a small room off a factory. There are 3 managerial offices, and 36 common-folk of various skill-sets in a variety of single to quad cubicles. No matter where you sit though, because of the layout and location, you've got a hard wall as one wall of your cubicle. Because of that hard wall, everything echoes. I get off the phone, and the guy in the next cubicle makes a comment in response to my phone conversation... I hate that it can be heard and I hate that they do that! These people have no problem yelling from cube to cube to carry on running conversations some of which are actually work-related. There's a lady two cubes away that talks so loud I can clearly hear every phone conversation she has... all work-related but still... Then the one in the next cubicle must have been raised on a farm because there's only one volume setting: LOUD... "HEY MARGE, CAN I GET IN FOR A QUICK APPOINTMENT AFTER WORK TONIGHT?" ... sigh Also that cube is the 'party cube' so that's where all the candy, cake, donuts, and leftovers sits. Anything MzLoud brings in has to have a verbal recipe associated with it at least 10 times during the day, and of course at volume. I've had running conversations over the top of my cube from people in the next one on each side. The weird thing is... the boss sits with an open door closer to this whole fiasco than me. So I wear a pair of Bose noise-cancelling headphones, and crank up Kenny Burrell, Herb Ellis, Wes Montgomery, or Jimmy Smith to the point I can't hear the racket... what the heck, I already have a hearing loss from playing guitar.
