  • Red Gate's on the road in 2012 - Will you catch us?

    - by RedAndTheCommunity
    Annabel Bradford, our Communities and Events Manager, tells all about her experience of our 1st SQL Saturday of the year. The first stop this year was SQL Saturday #104 Colorado Springs, back in early January. I made the trip across from the UK just for this SQL Saturday event, and I'm so glad I did. I picked up Max from Red Gate's Pasadena office and we flew into Colorado Springs airport late on Friday evening to be greeted by freezing temperatures, which was quite a shock after the California sunshine. Rising before the sun, we arrived at Mr Biggs, the venue for the event, in the darkness. It was great to see so many smiling attendees so bright and early on a Saturday morning. Everyone was eager to learn more about SQL Server, and hundreds of people came and chatted with us at the table, saw demos and learnt more about Red Gate tools. The event highlights for the attendees were definitely the unlimited lazer quest, bowling and pool available during the break times. For Max, Grant Fritchey and I on the Red Gate table, the highlights have to be meeting customers and getting the opportunity to meet attendees who'd heard of, but wanted to know more about, Red Gate. We were delighted to hear lots of valuable feedback that we took back to share with the team. As a thank you for sharing insights about their work lives and how they use SQL Server and Red Gate tools, attendees are able to take away Red Gate SQL Server books. We aim to have a range of titles available when we exhibit, so that attendees can choose a book that's going to be most interesting to them, and that they can use as a reference back at the office. Every time I meet a Red Gate user or a member of the SQL community, I'm always overwhelmed by the enthusiasm they have for their industry. Everyone who gives up their time to learn more about their job should be rewarded, and at Red Gate we like to do just that. Red Gate has long supported the SQL community through sponsorship to facilitate user group meetings and community events, but it's only though face-to-face contact that we really get a chance to see the impact of our support. I hope we'll have the chance to see you on the road at some point this year. We'll be at a range of events, including free SQL Saturdays, one day free events 'the Red Gate way', two-day Rallys, and full-week conferences. Next stop is SQL Saturday #109 Silicon Valley on March 3rd where you'll meet Jeff and Arneh, two of our US-based SQL team members. Be sure to ask them any questions you've got about the Red Gate tools, as these guys will be delighted to hear your questions, show you the options, and will make a note of your feedback to send through to the development team. Until the next time. Happy learning! Annabel                         Grant, Max and Annabel at SQL Saturday #104 Colorado Springs

  • Transform your Oracle Tutor Documents to Your Corporate Standard

    - by mary.keane
    You have all of your company's processes documented in Oracle Tutor, and now you want to get the HTML files to reflect your company's corporate look and feel. How are you going to do this without having an HTML guru to change every HTML page? The good news is you do not need to be an HTML expert to make minor changes to your documents. All Tutor HTML files are attached to a group of style sheets, so any changes you make to the style sheets will immediately be reflected in all of your HTML documents. If you want to give it a try, here's what you do (please note that these tips are applicable to release Oracle Tutor 12.2 and greater): Navigate to your Tutor HTML directory, and copy into a draft folder a representative group of HTML files (don't forget the flowchart image files that are associated with the procedures). You'll also need to copy the following files: tutor.css tutor_notabs.css tutor_scripts.js tutor_tabs.css flow_icon.gif Here's the default look to the Oracle Tutor desk manual. Let's say I want to use my company's corporate style in the HTML documents. At Oracle, we use Oracle Red (FF0000), Oracle Black (000000), and Oracle Gray (666666). So I want to incorporate those colors into the Tutor HTML files. I open tutor.css from the draft folder in a text editor. My preference is to use Notepad, but there are others. Make sure, however, that it is a text editor, and not a word processing program. I want to change the headings to Oracle Red. The desk manual title is listed as the DMPAGETITLE, so I find that in tutor.css. The style names in the style sheets are descriptive, but sometimes you may have to experiment to find the right style (this is why you're working in a draft folder). I change the color attribute to FF00000, and then I save the document. Now I look at one of the desk manuals in my draft folder. I've successfully changed the title of the desk manual, so, now that I have more confidence that I can do this, I start changing other styles. I need to make changes in the tutor_tabs.css file as well, so I open that document. Then I look at one of the procedures. Oops! All that red is distracting, and the users may not be able to follow their procedures. So I go back to the corporate style guide, and I find some shades of gray that have been approved. So I use that, and it is now more readable. It's good enough for a first draft, and I would show it to my colleagues at this point to get their input. On my next blog, I'll discuss how to change the flowchart colors to match your corporate look and feel. Have you used the cascading styles sheets to change the look of your Tutor documents? If so, let us know what you've done in your post. Mary R. Keane Senior Development Manager, Oracle Tutor & UPK Content

  • 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!

  • My Take on Hadoop World 2011

    - by Jean-Pierre Dijcks
    I’m sure some of you have read pieces about Hadoop World and I did see some headlines which were somewhat, shall we say, interesting? I thought the keynote by Larry Feinsmith of JP Morgan Chase & Co was one of the highlights of the conference for me. The reason was very simple, he addressed some real use cases outside of internet and ad platforms. The following are my notes, since the keynote was recorded I presume you can go and look at Hadoopworld.com at some point… On the use cases that were mentioned: ETL – how can I do complex data transformation at scale Doing Basel III liquidity analysis Private banking – transaction filtering to feed [relational] data marts Common Data Platform – a place to keep data that is (or will be) valuable some day, to someone, somewhere 360 Degree view of customers – become pro-active and look at events across lines of business. For example make sure the mortgage folks know about direct deposits being stopped into an account and ensure the bank is pro-active to service the customer Treasury and Security – Global Payment Hub [I think this is really consolidation of data to cross reference activity across business and geographies] Data Mining Bypass data engineering [I interpret this as running a lot of a large data set rather than on samples] Fraud prevention – work on event triggers, say a number of failed log-ins to the website. When they occur grab web logs, firewall logs and rules and start to figure out who is trying to log in. Is this me, who forget his password, or is it someone in some other country trying to guess passwords Trade quality analysis – do a batch analysis or all trades done and run them through an analysis or comparison pipeline One of the key requests – if you can say it like that – was for vendors and entrepreneurs to make sure that new tools work with existing tools. JPMC has a large footprint of BI Tools and Big Data reporting and tools should work with those tools, rather than be separate. Security and Entitlement – how to protect data within a large cluster from unwanted snooping was another topic that came up. I thought his Elephant ears graph was interesting (couldn’t actually read the points on it, but the concept certainly made some sense) and it was interesting – when asked to show hands – how the audience did not (!) think that RDBMS and Hadoop technology would overlap completely within a few years. Another interesting session was the session from Disney discussing how Disney is building a DaaS (Data as a Service) platform and how Hadoop processing capabilities are mixed with Database technologies. I thought this one of the best sessions I have seen in a long time. It discussed real use case, where problems existed, how they were solved and how Disney planned some of it. The planning focused on three things/phases: Determine the Strategy – Design a platform and evangelize this within the organization Focus on the people – Hire key people, grow and train the staff (and do not overload what you have with new things on top of their day-to-day job), leverage a partner with experience Work on Execution of the strategy – Implement the platform Hadoop next to the other technologies and work toward the DaaS platform This kind of fitted with some of the Linked-In comments, best summarized in “Think Platform – Think Hadoop”. In other words [my interpretation], step back and engineer a platform (like DaaS in the Disney example), then layer the rest of the solutions on top of this platform. One general observation, I got the impression that we have knowledge gaps left and right. On the one hand are people looking for more information and details on the Hadoop tools and languages. On the other I got the impression that the capabilities of today’s relational databases are underestimated. Mostly in terms of data volumes and parallel processing capabilities or things like commodity hardware scale-out models. All in all I liked this conference, it was great to chat with a wide range of people on Oracle big data, on big data, on use cases and all sorts of other stuff. Just hope they get a set of bigger rooms next time… and yes, I hope I’m going to be back next year!

  • 24 Hours of PASS: Whine, Whine, Whine

    - by Most Valuable Yak (Rob Volk)
    24 Hours of Pass (or 24HOP) is a great program offered by PASS to provide free, online training for anyone who wants to learn more about SQL Server.  They routinely have the best SQL Server presenters available for these sessions, and attract hundreds, perhaps even a thousand attendees from around the world.  This is definitely one of the best things they've started doing in the past few years, and every session I've attended has been excellent. So why am I so grumpy about it? I'm not really, pretty much everything here is a minor annoyance that I can deal with.  However since they're so minor they seem to be things that can be easily corrected and would make the process much better. First off, this is my biggest gripe, the registration page: https://www323.livemeeting.com/lrs/8000181573/Registration.aspx?pageName=lj6378f4fhf5hpdm What grinds my gears about this?  I have to scroll alllllllllllllllllllllllllllll the way to bottom to actually register for the sessions.  This wouldn't be so bad except all the details of the session, including the presenter, is in a separate list at the top.  Both lists contain info the other does not, and scrolling between them to determine "Should I make time to listen to this?  Who is speaking at this time anyway?" is really unnecessary. My preference would be to keep the top list and add the checkboxes and schedule info in separate columns.  This is a full-width design, so there's plenty of space for this data, which is pretty small anyway.  The other huge benefit is halving the size of the page, which improves performance and lowers bandwidth usage considerably.  And if you know HTML/ASP.Net, and you view the page source, you can find PLENTY of other things that can be reduced even further.  (not just viewstate) One nice thing that PASS does is send iCal reminders to your email address so you can accept them to your calendar.  Again, they leave off the presenter in the appointment details, while still duplicating the meeting title in the body.  Sometimes I make decisions based on speaker rather than content (Natalie Portman is reading the Yellow Pages??? I'M THERE!) and having the speaker in the iCal is helpful. Next minor annoyances are the necessity for providing a company name, and the survey questions.  I know PASS needs to market themselves effectively, and they need information to do that, and since this is a free event it's really not worth complaining about, but why ask the survey question twice? (once at registration, once again when joining the LiveMeeting)  Same thing for the company name.  All of this should be tied to email address, so that's all I should need to enter when joining the LiveMeeting. The last one is also minor, but it irks me in this day and age of multiple browsers and the decline of Internet Explorer as a dominant platform.  The registration page was originally created in Visual Studio 2003, and has a lot of IE-specific crud representative of the browser situation of 2003. (IE5 references? really? and is the aforementioned viewstate big enough?)  This causes some grief with other browsers like Firefox, Chrome, and sometimes IE8 or 9.  And don't get me started on using the page on a Mac or in Safari. My main point is that PASS is an international organization, welcoming everyone from all levels of SQL Server proficiency, and in that spirit I think it would help to accommodate a wider range of browser software, especially since the registration page is extremely simple.  I recognize that this page is not hosted on the PASS website and may be maintained by some division of Microsoft, but to me that's even worse if MS can't update their own pages.  They've deprecated IE6, so they don't need to maintain support on their own websites anymore. OK, I'll shut up now. #sqlpass #24HOP

  • PHP and Ruby: how to leverage both? and, is it worth it?

    - by dukeofgaming
    As you might have noticed from the title, this is not a "PHP or Ruby", or a "PHP vs. Ruby" question. This is a question on how to leverage PHP + Ruby in the same business. I myself am a PHP developer, I love the language because of its convenience and I specially love the ecosystem of resources that surround it: Joomla, Drupal, Wordpress, Symfony2, Doctrine2, etc. However, the language itself can be a little disappointing sometimes. OTOH, Ruby looks like a very beautiful language and —from studying it superficially in several aspects— I could say it is leaner than Python as a language per se. However, from what I've seen there is pretty much only RoR making noise, and I don't like RoR so much (mainly because its model layer). As Co-CEO and CTO at my company I'm trying to think outside of the box since I want to start to focus on the human side of technology and see if its sane to use both PHP and Ruby. Here are some random thoughts: Ruby folk seem to be generally better suited programmers than PHP folk (in terms of averages), I know the previous statement is somewhat baloney because very good and well architected PHP can be written, but I'd say the Ruby programmer culture is better than PHP's. The thing about Ruby is that it seems better suited for rapid development, I don't really know if this is only the case for RoR, but I do know that there are certain practices (perhaps not so good) like monkey patching that let business needs be satified quicker. From a marketing point of view (yep, sometimes you need to leverage the marketing BS for the sake of your company) Ruby seems better while PHP carries some stigmas. PHP 5.4 is bringing traits, and that is better/cleaner than mixins. That could really make PHP as lean as Ruby —or more— for certain stuff. Now, concretely, my questions: Would a PHP programmer want to learn Ruby?, I know I do, but conversely, would a Ruby programmer want to learn PHP?. What kinds of projects or situations would be better suited for Ruby that are not suited for PHP?. What is the actual ecosystem of Ruby?, aside from RoR, I have not seen other hyped technologies/frameworks (I've seen RSpec, but I confess being a total noob on what BDD really consists of and its implications). Supposing there are a certain type of projects ideal for Ruby, would there be a moment that its better to move it to PHP?. I know PHP can handle lots of stuff, but I've read that Ruby has its limitations when scaling (or is that RoR?, or is that baloney for both?). Finally and most importantly, would it be sane to maintain projects in two languages?, or is that just stupid. As I said, it looks like Ruby is leaner on the short term and that can make a project happen and succeed, but I'm not so sure about that on the long run. I'm looking for insights mainly from people that know well the strengths and weaknesses of the languages —preferably both of them— and Ruby's ecosystem in real practice, meaning: frameworks and applications like the ones I quoted from PHP's ecosystem. Best regards and thanks for your time.

  • Healthcare and Distributed Data Don't Mix

    - by [email protected]
    How many times have you heard the story?  Hard disk goes missing, USB thumb drive goes missing, laptop goes missing...Not a week goes by that we don't hear about our data going missing...  Healthcare data is a big one, but we hear about credit card data, pricing info, corporate intellectual property...  When I have spoken at Security and IT conferences part of my message is "Why do you give your users data to lose in the first place?"  I don't suggest they can't have access to it...in fact I work for the company that provides the premiere data security and desktop solutions that DO provide access.  Access isn't the issue.  'Keeping the data' is the issue.We are all human - we all make mistakes... I fault no one for having their car stolen or that they dropped a USB thumb drive. (well, except the thieves - I can certainly find some fault there)  Where I find fault is in policy (or lack thereof sometimes) that allows users to carry around private, and important, data with them.  Mr. Director of IT - It is your fault, not theirs.  Ms. CSO - Look in the mirror.It isn't like one can't find a network to access the data from.  You are on a network right now.  How many Wireless ones (wifi, mifi, cellular...) are there around you, right now?  Allowing employees to remove data from the confines of (wait for it... ) THE DATA CENTER is just plain indefensible when it isn't required.  The argument that the laptop had a password and the hard disk was encrypted is ridiculous.  An encrypted drive tells thieves that before they sell the stolen unit for $75, they should crack the encryption and ascertain what the REAL value of the laptop is... credit card info, Identity info, pricing lists, banking transactions... a veritable treasure trove of info people give away on an 'encrypted disk'.What started this latest rant on lack of data control was an article in Government Health IT that was forwarded to me by Denny Olson, an Oracle Principal Sales Consultant in Minnesota.  The full article is here, but the point was that a couple laptops went missing in a couple different cases, and.. well... no one knows where the data is, and yes - they were loaded with patient info.  What were you thinking?Obviously you can't steal data form a Sun Ray appliance... since it has no data, nor any storage to keep the data on, and Secure Global Desktop allows access from Macs, Linux and Windows client devices...  but in all cases, there is no keeping the data unless you explicitly allow for it in your policy.   Since you can get at the data securely from any network, why would you want to take personal responsibility for it?  Both Sun Rays and Secure Global Desktop are widely used in Healthcare... but clearly not widely enough.We need to do a better job of getting the message out -  Healthcare (or insert your business type here) and distributed data don't mix. Then add Hot Desking and 'follow me printing' and you have something that Clinicians (and CSOs) love.Thanks for putting up my blood pressure, Denny.

  • Bash completion doesn't work, or is ignoring what I've typed; but works for commands

    - by Neil Traft
    Bash completion seems to be ignoring what I've typed (it tries to complete, but acts as if there's nothing under the cursor). I know I saw it work on this machine earlier today, but I'm not sure what has changed. Some examples: cd shows all directories under my current folder: $ cd co<tab><tab> cmake/ config/ doc/ examples/ include/ programs/ sandbox/ src/ .svn/ tests/ Commands like ls and less show all files and directories under my current folder: $ ls co<tab><tab> cmake/ config/ .cproject Doxyfile.in include/ programs/ README.txt src/ tests/ CMakeLists.txt COPYING.txt doc/ examples/ mainpage.dox .project sandbox/ .svn/ Even when I try to complete things from a different folder, it gives me only the results for my current folder (telling me that it is completely ignoring what I've typed): $ cd ~/D<tab><tab> cmake/ config/ doc/ examples/ include/ programs/ sandbox/ src/ .svn/ tests/ But it seems to be working fine for commands and variables: $ if<tab><tab> if ifconfig ifdown ifnames ifquery ifup $ echo $P<tab><tab> $PATH $PIPESTATUS $PPID $PS1 $PS2 $PS4 $PWD $PYTHONPATH I do have this bit in my .bashrc, and I have confirmed that my .bashrc is indeed getting sourced: if [ -f /etc/bash_completion ] && ! shopt -oq posix; then . /etc/bash_completion fi I've even tried manually executing that file, but it doesn't fix the problem: $ . /etc/bash_completion There was even one point in time where it was working for ls, but was not working for cd ... but I can't replicate that result now.

  • Exposed: Fake Social Marketing

    - by Mike Stiles
    Brands and marketers who want to build their social popularity on a foundation of lies are starting to face more of an uphill climb. Fake social is starting to get exposed, and there are a lot of emperors getting caught without any clothes. Facebook is getting ready to do a purge of “Likes” on Pages that were a result of bots, fake accounts, and even real users who were duped or accidentally Liked a Page. Most of those accidental Likes occur on mobile, where it’s easy for large fingers to hit the wrong space. Depending on the degree to which your Page has been the subject of such activity, you may see your number of Likes go down. But don’t sweat it, that’s a good thing. The social world has turned the corner and assessed the value of a Like. And the verdict is that a Like is valuable as an opportunity to build a real relationship with a real customer. Its value pales immensely compared to a user who’s actually engaged with the brand. Those fake Likes aren’t doing you any good. Huge numbers may once have impressed, but it’s not fooling anybody anymore. Facebook’s selling point to marketers is the ability to use a brand’s fans to reach friends of those fans. Consequently, there has to be validity and legitimacy to a fan count. Speaking of mobile, Trademob recently reported 40% of clicks are essentially worthless, because 22% of them are accidental (again with the fat fingers), while 18% are trickery. Publishers will but huge banner ads next to tiny app buttons to increase the odds of an accident. Others even hide a banner behind another to score 2 clicks instead of 1. Pontiflex and Harris Interactive last year found 47% of users were more likely to click a mobile ad accidentally than deliberately. Beyond that, hijacked devices are out there manipulating click data. But to what end for a marketer? What’s the value of a click on something a user never even saw? What’s the value of a seen but accidentally clicked ad if there’s no resulting transaction? Back to fake Likes, followers and views; they’re definitely for sale on numerous sites, none of which I’ll promote. $5 can get you 1,000 Twitter followers. You can even get followers targeted by interests. One site was set up by an unemployed accountant out of his house in England. He gets them from a wholesaler in Brooklyn, who gets them from a 19-year-old supplier in India. The unemployed accountant is making $10,000 a day. That means a lot of brands, celebrities and organizations are playing the fake social game, apparently not coming to grips with the slim value of the numbers they’re buying. But now, in addition to having paid good money for non-ROI numbers, there’s the embarrassment factor. At least a couple of sites have popped up allowing anyone to see just how many fake and inactive followers you have. Britain’s Fake Follower Check and StatusPeople are the two getting the most attention. Enter any Twitter handle and the results are there for all to see. Fake isn’t good, period. “Inactive” could be real followers, but if they’re real, they’re just watching, not engaging. If someone runs a check on your Twitter handle and turns up fake followers, does that mean you’re suspect or have purchased followers? No. Anyone can follow anyone, so most accounts will have some fakes. Even account results like Barack Obama’s (70% fake according to StatusPeople) and Lady Gaga’s (71% fake) don’t mean these people knew about all those fakes or initiated them. Regardless, brands should realize they’re now being watched, and users are judging the legitimacy of their social channels. Use one of any number of tools available to assess and clean out fake Likes and followers so that your numbers are as genuine as possible. And obviously, skip the “buying popularity” route of social marketing strategy. It doesn’t work and it gets you busted…a losing combination.

  • IIS not starting: The process cannot access the file because it is being used by another process

    - by Rick Strahl
    Ok, apparently a few people knew about this issue, but it is new to me and has caused me nearly an hour to track down today. What happened is that I’ve been working all day doing some final pre-deployment testing of several tools on my local dev machine. In the process I’ve been starting and stopping several IIS 7 Web sites. At some point I was done and just wanted to start my Default Web Site again and found this  little gem of an error message popping up: The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0x80070020) A lot of headless running around ensued after this, trying to figure out why IIS wouldn’t start. Oddly some sites started right up, others didn’t. I killed INetInfo, all worker processes, tried IISReset a million times and even rebooted – all to no avail. What gives? Skype, you evil Bastard! As it turns out the culprit is – drum roll please - Skype!  What, you may ask, does Skype have to do with IIS and Web Requests? It looks like recent versions of Skype have an option to run over Port 80 and 443 to allow running over corporate firewalls. Which is actually a nice feature that lets Skype work just about anywhere. What’s not so cool is that IIS fails to start up when another application is already using the same port that a Web site is mapped to. In the case of my dev site that’d be port 80 and Skype was hogging it. To fix this issue you can stop Skype from using port 80 and 443 which quickly fixes the problem. Or stop Skype. Duh! To permanently fix the problem in Skype find the option on the Options | Connection tab and uncheck the Use port 80/443 option: Oddly I haven’t run into this problem even though my setup hasn’t changed in quite some time. It appears that it’s bad startup timing that causes this problem to occur. Whatever the circumstance was, Skype somehow ended up starting before IIS.  If Skype is started after IIS has started it will automatically opt for other ports and not use port 80 and so there’s no problem. It’s easy to demonstrate this behavior if you’re looking for it: Stop IIS Stop Skype Start Skype and make a test call Start IIS And voila your error is ready for you! This really shouldn’t be a problem except that it would be really nice if IIS could give a more helpful error message when it can fire up a site because a port is blocked. “The process cannot access a file” is really not a very helpful error message in this scenario… I/O port / file ah what the heck it’s all the same to Windows. Right! I’ve run into this situation quite a bit with other, albeit more obvious applications like running Apache on the local machine for testing and then trying to run an IIS application. Same situation,  although it’s been a while – pre IIS 7 and I think previous versions of IIS actually gave more useful error messages for port blockages and that would be helpful. On the way to figuring this out I ran into some pretty humorous forum posts though with people ragging on why the hell you would be running IIS. Or Skype. The misinformed paranoia police out in full force so to say :-). It’ll be nice to start running IIS Express once Visual Studio 2010 SP1 gets released. Anyway, no surprise that Skype didn’t jump out at me as the culprit right away and I was left fumbling for a while until the Internet came to the rescue. I’m not the first to have found this for sure – I posted a message on Twitter and dozens of people replied they’d run into this before as well. Seems worth mentioning again though – since I’m sure to forget that this happened in a year from now when I hit that same error. Maybe I’ll even find this blog post to remind me…© Rick Strahl, West Wind Technologies, 2005-2011Posted in IIS7  Windows

  • Finding the maximum value/date across columns

    - by AtulThakor
    While working on some code recently I discovered a neat little trick to find the maximum value across several columns….. So the starting point was finding the maximum date across several related tables and storing the maximum value against an aggregated record. Here's the sample setup code: USE TEMPDB IF OBJECT_ID('CUSTOMER') IS NOT NULL BEGIN DROP TABLE CUSTOMER END IF OBJECT_ID('ADDRESS') IS NOT NULL BEGIN DROP TABLE ADDRESS END IF OBJECT_ID('ORDERS') IS NOT NULL BEGIN DROP TABLE ORDERS END SELECT 1 AS CUSTOMERID, 'FREDDY KRUEGER' AS NAME, GETDATE() - 10 AS DATEUPDATED INTO CUSTOMER SELECT 100000 AS ADDRESSID, 1 AS CUSTOMERID, '1428 ELM STREET' AS ADDRESS, GETDATE() -5 AS DATEUPDATED INTO ADDRESS SELECT 123456 AS ORDERID, 1 AS CUSTOMERID, GETDATE() + 1 AS DATEUPDATED INTO ORDERS .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   Now the code used a function to determine the maximum date, this performed poorly. After considering pivoting the data I opted for a case statement, this seemed reasonable until I discovered other areas which needed to determine the maximum date between 5 or more tables which didn't scale well. The final solution involved using the value clause within a sub query as followed. SELECT C.CUSTOMERID, A.ADDRESSID, (SELECT MAX(DT) FROM (Values(C.DATEUPDATED),(A.DATEUPDATED),(O.DATEUPDATED)) AS VALUE(DT)) FROM CUSTOMER C INNER JOIN ADDRESS A ON C.CUSTOMERID = A.CUSTOMERID INNER JOIN ORDERS O ON O.CUSTOMERID = C.CUSTOMERID .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } As you can see the solution scales well and can take advantage of many of the aggregate functions!

  • Ubuntu Server 12 not spawning a serial ttyS0 when running on Xen

    - by segfaultreloaded
    I have this problem on more than one host, so the specific hardware is not an issue. Bare metal Ubuntu 12 is not creating a login process on the only serial port, in the default configuration. The serial port works correctly with the firmware. It works correctly with Grub2.

  • Camera frustum calculation coming out wrong

    - by Telanor
    I'm trying to calculate a view/projection/bounding frustum for the 6 directions of a point light and I'm having trouble with the views pointing along the Y axis. Our game uses a right-handed, Y-up system. For the other 4 directions I create the LookAt matrix using (0, 1, 0) as the up vector. Obviously that doesn't work when looking along the Y axis so for those I use an up vector of (-1, 0, 0) for -Y and (1, 0, 0) for +Y. The view matrix seems to come out correctly (and the projection matrix always stays the same), but the bounding frustum is definitely wrong. Can anyone see what I'm doing wrong? This is the code I'm using: camera.Projection = Matrix.PerspectiveFovRH((float)Math.PI / 2, ShadowMapSize / (float)ShadowMapSize, 1, 5); for(var i = 0; i < 6; i++) { var renderTargetView = shadowMap.GetRenderTargetView((TextureCubeFace)i); var up = DetermineLightUp((TextureCubeFace) i); var forward = DirectionToVector((TextureCubeFace) i); camera.View = Matrix.LookAtRH(this.Position, this.Position + forward, up); camera.BoundingFrustum = new BoundingFrustum(camera.View * camera.Projection); } private static Vector3 DirectionToVector(TextureCubeFace direction) { switch (direction) { case TextureCubeFace.NegativeX: return -Vector3.UnitX; case TextureCubeFace.NegativeY: return -Vector3.UnitY; case TextureCubeFace.NegativeZ: return -Vector3.UnitZ; case TextureCubeFace.PositiveX: return Vector3.UnitX; case TextureCubeFace.PositiveY: return Vector3.UnitY; case TextureCubeFace.PositiveZ: return Vector3.UnitZ; default: throw new ArgumentOutOfRangeException("direction"); } } private static Vector3 DetermineLightUp(TextureCubeFace direction) { switch (direction) { case TextureCubeFace.NegativeY: return -Vector3.UnitX; case TextureCubeFace.PositiveY: return Vector3.UnitX; default: return Vector3.UnitY; } } Edit: Here's what the values are coming out to for the PositiveX and PositiveY directions: Constants: Position = {X:0 Y:360 Z:0} camera.Projection = [M11:0.9999999 M12:0 M13:0 M14:0] [M21:0 M22:0.9999999 M23:0 M24:0] [M31:0 M32:0 M33:-1.25 M34:-1] [M41:0 M42:0 M43:-1.25 M44:0] PositiveX: up = {X:0 Y:1 Z:0} target = {X:1 Y:360 Z:0} camera.View = [M11:0 M12:0 M13:-1 M14:0] [M21:0 M22:1 M23:0 M24:0] [M31:1 M32:0 M33:0 M34:0] [M41:0 M42:-360 M43:0 M44:1] camera.BoundingFrustum: Matrix = [M11:0 M12:0 M13:1.25 M14:1] [M21:0 M22:0.9999999 M23:0 M24:0] [M31:0.9999999 M32:0 M33:0 M34:0] [M41:0 M42:-360 M43:-1.25 M44:0] Top = {A:0.7071068 B:-0.7071068 C:0 D:254.5584} Bottom = {A:0.7071068 B:0.7071068 C:0 D:-254.5584} Left = {A:0.7071068 B:0 C:0.7071068 D:0} Right = {A:0.7071068 B:0 C:-0.7071068 D:0} Near = {A:1 B:0 C:0 D:-1} Far = {A:-1 B:0 C:0 D:5} PositiveY: up = {X:0 Y:0 Z:-1} target = {X:0 Y:361 Z:0} camera.View = [M11:-1 M12:0 M13:0 M14:0] [M21:0 M22:0 M23:-1 M24:0] [M31:0 M32:-1 M33:0 M34:0] [M41:0 M42:0 M43:360 M44:1] camera.BoundingFrustum: Matrix = [M11:-0.9999999 M12:0 M13:0 M14:0] [M21:0 M22:0 M23:1.25 M24:1] [M31:0 M32:-0.9999999 M33:0 M34:0] [M41:0 M42:0 M43:-451.25 M44:-360] Top = {A:0 B:0.7071068 C:0.7071068 D:-254.5585} Bottom = {A:0 B:0.7071068 C:-0.7071068 D:-254.5585} Left = {A:-0.7071068 B:0.7071068 C:0 D:-254.5585} Right = {A:0.7071068 B:0.7071068 C:0 D:-254.5585} Near = {A:0 B:1 C:0 D:-361} Far = {A:0 B:-1 C:0 D:365} When I use the resulting BoundingFrustum to cull regions outside of it, this is the result: Pass PositiveX: Drew 3 regions Pass NegativeX: Drew 6 regions Pass PositiveY: Drew 400 regions Pass NegativeY: Drew 36 regions Pass PositiveZ: Drew 3 regions Pass NegativeZ: Drew 6 regions There are only 400 regions to draw and the light is in the center of them. As you can see, the PositiveY direction is drawing every single region. With the near/far planes of the perspective matrix set as small as they are, there's no way a single frustum could contain every single region.

  • JD Edwards Apps in a Box - Update

    - by Hartmut Wiese
    Summary and clarification JD Edwards Apps in a box is a Partner offering to the customer. We as Oracle have a huge interest in getting a successful offering to the market and we help the Partner building their offering. We provide components like JD Edwards EnterpriseOne and the Hardware. The Business Partner adds the installation services and position this as a solution to the market for a single price. As you know JD Edwards EnterpriseOne can run on multiple hardware platforms. Linux/X-86 version As you all know we do have JD Edwards VM Templates available from Oracle for the X-86 architecture. Each Partner should or is already able to install JD Edwards EnterpriseOne using these images from our software delivery cloud. We built a master bill of material for a X3-2 Hardware configuration now. It has been uploaded on the Community Workspace now. This is a SUGGESTION and limited to 50 Users MAX. However I strongly recommend you to do a sizing as usual and verify the configuration for each opportunity individually. T4-1/X3-2 version Oracle is not providing similar images for the T4-1 SPARC / SOLARIS architecture. There is an Optimized Solution Team inside Oracle who has created an Optimized Solution for JD Edwards some time ago. They created a whitepaper which is still available to download. This whitepaper was used as a starting point however we decided to build a new version of it using the latest Software and Hardware available. This has now been finalized and we are happy to provide this to our partners. This image is more a service we provide for each partner which they can reuse and extend based on their individual offerings. It is not an official supported Oracle Product and cannot be used to deploy to customers immediately. You cannot resell “JDE in a box”. You can use these images to save time while building your own Go-to-Market offering. You might want to add functionality like Mobility. It is also not complete as also the Deployment Server needs to be configured individually at the customer site. We will create some documentation about: what this images contains (and what not)? what final installation activities needs to be provided by each VAD/Partner in this process?  I will send an email to the community once we are ready to share it. You find these assets than in the Community Workspace. The Business Model with Oracle Hardware For those who have not done any Hardware business with Oracle yet: Usually a HW reseller orders the hardware through a Value Add Distributors (VAD) and not from Oracle directly. Each Partner needs to have Hardware Resell rights to do so. The VAD is assembling the boxes according to the needs of each customer. It is easily possible for them to prepare the boxes with the images we/you provide. However the final configuration is something a reseller/implementer needs to do at the customer site. This process is not the same in the EMEA region. Sometimes a VAD are taking the order but they do not see the Hardware at all. In those cases a VAD cannot provide any help with the pre-loading of any images and the reseller/implementer needs to do that. In some countries we do not have VADs at all.

  • MySql Connector/NET 6.7.4 GA has been released

    - by fernando
    MySQL Connector/Net 6.7.4, a new version of the all-managed .NET driver for MySQL has been released.  This is the GA, is feature complete. It is recommended for production environments.  It is appropriate for use with MySQL server versions 5.0-5.7.  It is now available in source and binary form from http://dev.mysql.com/downloads/connector/net/#downloads and mirror sites (note that not all mirror sites may be up to date at this point-if you can't find this version on some mirror, please try again later or choose another download site.) The 6.7 version of MySQL Connector/Net brings the following new features: -  WinRT Connector. -  Load Balancing support. -  Entity Framework 5.0 support. -  Memcached support for Innodb Memcached plugin. -  This version also splits the product in two: from now on, starting version 6.7, Connector/NET will include only the former Connector/NET ADO.NET driver, Entity Framework and ASP.NET providers (Core libraries of MySql.Data, MySql.Data.Entity & MySql.Web). While all the former product Visual Studio integration (Design support, Intellisense, Debugger) are available as part of MySql Windows Installer under the name "MySql for Visual Studio".  WinRT Connector  ------------------------------------------- Now you can write MySql data access apps in Windows Runtime (aka Store Apps) using the familiar API of Connector/NET for .NET.  Load Balancing Support  -------------------------------------------  Now you can setup a Replication or Cluster configuration in the backend, and Connector/NET will balance the load of queries among all servers making up the backend topology.  Entity Framework 5.0  -------------------------------------------  Connector/NET is now compatible with EF 5, including special features of EF 5 like spatial types.  Memcached  -------------------------------------------  Just setup Innodb memcached plugin and use Connector/NET new APIs to establish a client to MySql 5.6 server's memcached daemon.  Bug fixes included in this release: - Fix for Entity Framework when inserts data having Identity columns (Oracle bug #16494585). - Fix for Connector/NET cannot read data from a MySql table using UTF-16/UTF-32 (MySql bug #69169, Oracle bug #16776818). - Fix for Malformed query in Entity Framework when eager loading due to multiple projections (MySql bug #67183, Oracle bug #16872852). - Fix for database objects with 'dbo' prefix when using automatic migrations in Entity Framework 5.0 (Oracle bug #16909439). - Fix for bug IIS application pool reset worker process causes website to crash (Oracle bug #16909237, Mysql Bug #67665). - Fix for bug Error in LINQ to Entities query when using Distinct().Count() (MySql Bug #68513, Oracle bug #16950146). - Fix for occasionally return no data when socket connection is slow, interrupted or delayed (MySql bug #69039, Oracle bug #16950212). - Fix for ConstraintException when filling a datatable (MySql bug #65065, Oracle bug #16952323). - Fix for Data Provider is not found after uninstalling Mysql for visual studio (Oracle bug #16973456). - Fix for nested sql generated for LINQ to Entities query with Take and Order by (MySql bug #65723, Oracle bug #16973939). The documentation is available at http://dev.mysql.com/doc/refman/5.7/en/connector-net.html  Enjoy and thanks for the support!  --  Fernando Gonzalez Sanchez | Software Engineer |  Oracle MySQL Windows Experience Team, Connector/NET  Guadalajara | Jalisco | Mexico

  • Give a session on C++ AMP – here is how

    - by Daniel Moth
    Ever since presenting on C++ AMP at the AMD Fusion conference in June, then the Gamefest conference in August, and the BUILD conference in September, I've had numerous requests about my material from folks that want to re-deliver the same session. The C++ AMP session I put together has evolved over the 3 presentations to its final form that I used at BUILD, so that is the one I recommend you base yours on. Please get the slides and the recording from channel9 (I'll refer to slide numbers below). This is how I've been presenting the C++ AMP session: Context (slide 3, 04:18-08:18) Start with a demo, on my dual-GPU machine. I've been using the N-Body sample (for VS 11 Developer Preview). (slide 4) Use an nvidia slide that has additional examples of performance improvements that customers enjoy with heterogeneous computing. (slide 5) Talk a bit about the differences today between CPU and GPU hardware, leading to the fact that these will continue to co-exist and that GPUs are great for data parallel algorithms, but not much else today. One is a jack of all trades and the other is a number cruncher. (slide 6) Use the APU example from amd, as one indication that the hardware space is still in motion, emphasizing that the C++ AMP solution is a data parallel API, not a GPU API. It has a future proof design for hardware we have yet to see. (slide 7) Provide more meta-data, as blogged about when I first introduced C++ AMP. Code (slide 9-11) Introduce C++ AMP coding with a simplistic array-addition algorithm – the slides speak for themselves. (slide 12-13) index<N>, extent<N>, and grid<N>. (Slide 14-16) array<T,N>, array_view<T,N> and comparison between them. (Slide 17) parallel_for_each. (slide 18, 21) restrict. (slide 19-20) actual restrictions of restrict(direct3d) – the slides speak for themselves. (slide 22) bring it altogether with a matrix multiplication example. (slide 23-24) accelerator, and accelerator_view. (slide 26-29) Introduce tiling incl. tiled matrix multiplication [tiling probably deserves a whole session instead of 6 minutes!]. IDE (slide 34,37) Briefly touch on the concurrency visualizer. It supports GPU profiling, but enhancements specific to C++ AMP we hope will come at the Beta timeframe, which is when I'll be spending more time talking about it. (slide 35-36, 51:54-59:16) Demonstrate the GPU debugging experience in VS 11. Summary (slide 39) Re-iterate some of the points of slide 7, and add the point that the C++ AMP spec will be open for other compiler vendors to implement, even on other platforms (in fact, Microsoft is actively working on that). (slide 40) Links to content – see slide – including where all your questions should go: http://social.msdn.microsoft.com/Forums/en/parallelcppnative/threads.   "But I don't have time for a full blown session, I only need 2 (or just 1, or 3) C++ AMP slides to use in my session on related topic X" If all you want is a small number of slides, you can take some from the session above and customize them. But because I am so nice, I have created some slides for you, including talking points in the notes section. Download them here. Comments about this post by Daniel Moth welcome at the original blog.

  • Welcome to the Oracle Retail International Blog

    - by sarah.taylor(at)oracle.com
    Welcome to the first post of the new Oracle Retail International Blog. Retail is an international business and today's successful retailers view themselves in the context of a global market. A niche fashion business in Tokyo will learn marketing strategies from the luxury brands of Milan, an independent grocer in Oslo will source the same global brands as a supermarket in Oklahoma, and every retailer in the world will measure their multi-channel operation against the international e-commerce giant Amazon.  Why? Because today's customer is a global customer with unparalleled expectations on choice, price and service. Today's consumers have access to more information on retail than ever before. Technology allows people to shop from their home, their office or from the phone in their pocket, wherever they are and at whatever time suits them. Customers are using the web to search for products and promotions. They are also using the web to develop their voice in commenting on products and services that have delighted or disappointed. In an information rich industry, this customer element creates a new world of data. The best retailers are developing eagle eyes for reading customer activity and turning it into profitable decisions. Ultimately, whether you choose to compete or shop on price, service, product innovation, excellent operations or all of the above - the international world of retail has become an inspiration for all - retailer and consumer alike.  Retail as an industry is growing and diversifying at a faster rate than ever before. Yet it is still the customer who picks the winners and the losers on the retail field. Economic circumstances transform the rules, but it is still the customer who dictates the game, the pace, the price, and the perception of the brand. Wise retailers never rest on their laurels. They are always shopping for ideas on how to improve and differentiate the offer at every touch point to meet the customer's needs better than anyone else and to gain each customer's loyalty at a time when loyalty can be cheap. With this blog, I hope that we might provide a hub for discussion around what unifies retail and how technology supports both the retailer and customer experience. Despite the competitive nature of this market, we hope that this will provide an opportunity to share experiences and lessons learnt with a view that knowledge can only help this industry to grow and develop. At Oracle we've been supporting retailers for many years. Many of us have worked within retail organisations all over the world, myself included. With this in mind, I don't feel it is too bold a statement to say that Oracle understands retail. We wouldn't be so heavily integrated in some of the biggest and most well-known names in retail if we didn't. With this blog, we intend to create a community of international retailers that can exchange ideas and experiences, debate collective challenges and drive a better understanding of this continually evolving industry. Events such as the World Retail Congress and NRF's Big Show bring enormous value to the retail industry providing platforms for discussion and learning but they happen once a year. We wanted to create a platform for discussion on a different level and that like retail, is always on. We hope not only to bring commitment to being not only the infrastructure that brings all of their systems together within a retail business, but an infrastructure that supports the industry internationally to grow and flourish through creating a platform for networking, discussion, creativity, vision and strategy. Please feel free to ask questions or comment using the comments functionality.  You might also want to visit our other Oracle Retail social media sites: Facebook - http://www.facebook.com/oracleretail YouTube - http://www.youtube.com/user/oracleretail Twitter - http://twitter.com/#!/oracleretailInsight-Driven Retailing Blog - http://blogs.oracle.com/retail/

  • Visual Studio Little Wonders: Quick Launch / Quick Access

    - by James Michael Hare
    Once again, in this series of posts I look at features of Visual Studio that may seem trivial, but can help improve your efficiency as a developer. The index of all my past little wonders posts can be found here. Well, my friends, this post will be a bit short because I’m in the middle of a bit of a move at the moment.  But, that said, I didn’t want to let the blog go completely silent this week, so I decided to add another Little Wonder to the list for the Visual Studio IDE. How often have you wanted to change an option or execute a command in Visual Studio, but can’t remember where the darn thing is in the menu, settings, etc.?  If so, Quick Launch in VS2012 (or Quick Access in VS2010 with the Productivity Power Tools extension) is just for you! Quick Launch / Quick Access – find a command or option quickly For those of you using Visual Studio 2012, Quick Launch is built right into the IDE at the top of the title bar, near the minimize, maximize, and close buttons: But do not despair if you are using Visual Studio 2010, you can get Quick Access from the Productivity Power Tools extension.  To do this, you can go to the extension manager: And then go to the gallery and search for Productivity Power Tools and install it.  If you don’t have VS2012 yet, then the Productivity Power Tools is the next best thing.  This extension updates VS2010 with features such as Quick Access, the Solution Navigator, searchable Add Reference Dialog, better tab wells, etc.  I highly recommend it! But back to the topic at hand!  In VS2012 Quick Launch is built into the IDE and can be accessed by clicking in the Quick Launch area of the title bar, or by pressing CTRL+Q.  If you have VS2010 with the PPT installed, though, it is called Quick Access and is accessible through View –> Quick Access: Regardless of which IDE you are using, the feature behaves mostly the same.  It allows you to search all of Visual Studio’s commands and options for a particular topic.  For example, let’s say you want to change from tabs to tabs expanded to spaces, but don’t remember where that option is buried.  You can bring up Quick Launch / Quick Access and type in “tabs”: And it brings up a list of all options on tabs, you can then choose the one appropriate to you and click on it and it will take you right there! A lot easier than diving through the options tree to find what you are looking for!  It also works on menu commands, for example if you can’t remember how to open the Output window: It shows you the menu items that will get you to the Output window, and (if applicable) the keyboard shortcuts.  Again, clicking on one of these will perform the action for you as well. There are also some tasks you can perform directly from Quick Launch / Quick Access.  For example, perhaps you are one of those people who like to have the line numbers in your editor (I do), so let’s bring up Quick Launch / Quick Access and type “line numbers”: And let’s select Turn Line Numbers On, and now our editor looks like: And Voila!  We have line numbers in VS2010.  You can do this in VS2012 too, but it takes you to the option settings instead of directly turning them off and on.  There are bound to be differences between the way the two editors organize settings and commands, but you get the point. So, as you can see, the Quick Launch / Quick Access feature in Visual Studio makes it easy to jump right to the options, commands, or tasks you are interested in without all the digging. Summary An IDE as powerful as Visual Studio has so many options and commands that it can be confusing to remember how to find and invoke them.  Quick Launch (Quick Access in VS2010 with Productivity Power Tools extension) is a quick and handy way to jump to any of these options, commands, or tasks quickly without having to remember in what menu or screen they are buried!  Technorati Tags: C#,CSharp,.NET,Little Wonders,Visual Studio,Quick Access,Quick Launch

  • Automated SSRS deployment with the RS utility

    - by Stacy Vicknair
    If you’re familiar with SSRS and development you are probably aware of the SSRS web services. The RS utility is a tool that comes with SSRS that allows for scripts to be executed against against the SSRS web service without needing to create an application to consume the service. One of the better benefits of using this format rather than writing an application is that the script can be modified by others who might be involved in the creation and addition of scripts or management of the SSRS environment.   Reporting Services Scripter Jasper Smith from http://www.sqldbatips.com created Reporting Services Scripter to assist with the created of a batch process to deploy an entire SSRS environment. The helper scripts below were created through the modification of his generated scripts. Why not just use this tool? You certainly can. For me, the volume of scripts generated seems less maintainable than just using some common methods extracted from these scripts and creating a deployment in a single script file. I would, however, recommend this as a product if you do not think that your environment will change drastically or if you do not need to deploy with a higher level of control over the deployment. If you just need to replicate, this tool works great. Executing with RS.exe Executing a script against rs.exe is fairly simple. The Script Half the battle is having a starting point. For the scripting I needed to do the below is the starter script. A few notes: This script assumes integrated security. This script assumes your reports have one data source each. Both of the above are just what made sense for my scenario and are definitely modifiable to accommodate your needs. If you are unsure how to change the scripts to your needs, I recommend Reporting Services Scripter to help you understand how the differences. The script has three main methods: CreateFolder, CreateDataSource and CreateReport. Scripting the server deployment is just a process of recreating all of the elements that you need through calls to these methods. If there are additional elements that you need to deploy that aren’t covered by these methods, again I suggest using Reporting Services Scripter to get the code you would need, convert it to a repeatable method and add it to this script! Public Sub Main() CreateFolder("/", "Data Sources") CreateFolder("/", "My Reports") CreateDataSource("/Data Sources", "myDataSource", _ "Data Source=server\instance;Initial Catalog=myDatabase") CreateReport("/My Reports", _ "MyReport", _ "C:\myreport.rdl", _ True, _ "/Data Sources", _ "myDataSource") End Sub   Public Sub CreateFolder(parent As String, name As String) Dim fullpath As String = GetFullPath(parent, name) Try RS.CreateFolder(name, parent, GetCommonProperties()) Console.WriteLine("Folder created: {0}", name) Catch e As SoapException If e.Detail.Item("ErrorCode").InnerText = "rsItemAlreadyExists" Then Console.WriteLine("Folder {0} already exists and cannot be overwritten", fullpath) Else Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End If End Try End Sub   Public Sub CreateDataSource(parent As String, name As String, connectionString As String) Try RS.CreateDataSource(name, parent,False, GetDataSourceDefinition(connectionString), GetCommonProperties()) Console.WriteLine("DataSource {0} created successfully", name) Catch e As SoapException Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End Try End Sub   Public Sub CreateReport(parent As String, name As String, location As String, overwrite As Boolean, dataSourcePath As String, dataSourceName As String) Dim reportContents As Byte() = Nothing Dim warnings As Warning() = Nothing Dim fullpath As String = GetFullPath(parent, name)   'Read RDL definition from disk Try Dim stream As FileStream = File.OpenRead(location) reportContents = New [Byte](stream.Length-1) {} stream.Read(reportContents, 0, CInt(stream.Length)) stream.Close()   warnings = RS.CreateReport(name, parent, overwrite, reportContents, GetCommonProperties())   If Not (warnings Is Nothing) Then Dim warning As Warning For Each warning In warnings Console.WriteLine(Warning.Message) Next warning Else Console.WriteLine("Report: {0} published successfully with no warnings", name) End If   'Set report DataSource references Dim dataSources(0) As DataSource   Dim dsr0 As New DataSourceReference dsr0.Reference = dataSourcePath Dim ds0 As New DataSource ds0.Item = CType(dsr0, DataSourceDefinitionOrReference) ds0.Name=dataSourceName dataSources(0) = ds0     RS.SetItemDataSources(fullpath, dataSources)   Console.Writeline("Report DataSources set successfully")       Catch e As IOException Console.WriteLine(e.Message) Catch e As SoapException Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End Try End Sub     Public Function GetCommonProperties() As [Property]() 'Common CatalogItem properties Dim descprop As New [Property] descprop.Name = "Description" descprop.Value = "" Dim hiddenprop As New [Property] hiddenprop.Name = "Hidden" hiddenprop.Value = "False"   Dim props(1) As [Property] props(0) = descprop props(1) = hiddenprop Return props End Function   Public Function GetDataSourceDefinition(connectionString as String) Dim definition As New DataSourceDefinition definition.CredentialRetrieval = CredentialRetrievalEnum.Integrated definition.ConnectString = connectionString definition.Enabled = True definition.EnabledSpecified = True definition.Extension = "SQL" definition.ImpersonateUser = False definition.ImpersonateUserSpecified = True definition.Prompt = "Enter a user name and password to access the data source:" definition.WindowsCredentials = False definition.OriginalConnectStringExpressionBased = False definition.UseOriginalConnectString = False Return definition End Function   Private Function GetFullPath(parent As String, name As String) As String If parent = "/" Then Return parent + name Else Return parent + "/" + name End If End Function

  • How to check if a cdrom is in the tray remotely (via ssh)?

    - by adempewolff
    I have a server running Ubuntu 10.04 (it's on the other side of the world and I haven't built up the wherewithal to upgrade it remotely yet) and I have been told that there is a CD in one of it's two CD drives. I want to rip an image of the cd and then download it to my local computer (I don't need help with either of these steps). However, I cannot seem to confirm whether or not there actually is a CD in the drive as I was told. It did not automatically mount anywhere (which I'm thinking might just be a result of it being a headless server not running X, nautilus, or any of the other nice user friendly things). There are two CD drives connected via SCSI: austin@austinvpn:/proc/scsi$ cat /proc/scsi/scsi Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: ATA Model: WDC WD400EB-75CP Rev: 06.0 Type: Direct-Access ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 00 Lun: 00 Vendor: Lite-On Model: LTN486S 48x Max Rev: YDS6 Type: CD-ROM ANSI SCSI revision: 05 Host: scsi1 Channel: 00 Id: 01 Lun: 00 Vendor: SAMSUNG Model: CD-R/RW SW-248F Rev: R602 Type: CD-ROM ANSI SCSI revision: 05 However when I try mounting either of these devices (and every other device that could possibly be the cd-drive), it says no medium found: austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/scd1 /cdrom mount: no medium found on /dev/sr1 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/scd0 /cdrom mount: no medium found on /dev/sr0 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrom /cdrom mount: no medium found on /dev/sr1 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrom1 /cdrom mount: no medium found on /dev/sr0 austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrw /cdrom mount: no medium found on /dev/sr1 Here are the contents of my /dev folder: austin@austinvpn:/proc/scsi$ ls /dev agpgart loop6 ram6 tty10 tty38 tty8 austinvpn loop7 ram7 tty11 tty39 tty9 block lp0 ram8 tty12 tty4 ttyS0 bsg mapper ram9 tty13 tty40 ttyS1 btrfs-control mcelog random tty14 tty41 ttyS2 bus mem rfkill tty15 tty42 ttyS3 cdrom net root tty16 tty43 urandom cdrom1 network_latency rtc tty17 tty44 usbmon0 cdrw network_throughput rtc0 tty18 tty45 usbmon1 char null scd0 tty19 tty46 usbmon2 console oldmem scd1 tty2 tty47 usbmon3 core parport0 sda tty20 tty48 usbmon4 cpu_dma_latency pktcdvd sda1 tty21 tty49 vcs disk port sda2 tty22 tty5 vcs1 dri ppp sda5 tty23 tty50 vcs2 ecryptfs psaux sg0 tty24 tty51 vcs3 fb0 ptmx sg1 tty25 tty52 vcs4 fd pts sg2 tty26 tty53 vcs5 full ram0 shm tty27 tty54 vcs6 fuse ram1 snapshot tty28 tty55 vcs7 hpet ram10 snd tty29 tty56 vcsa input ram11 sndstat tty3 tty57 vcsa1 kmsg ram12 sr0 tty30 tty58 vcsa2 log ram13 sr1 tty31 tty59 vcsa3 loop0 ram14 stderr tty32 tty6 vcsa4 loop1 ram15 stdin tty33 tty60 vcsa5 loop2 ram2 stdout tty34 tty61 vcsa6 loop3 ram3 tty tty35 tty62 vcsa7 loop4 ram4 tty0 tty36 tty63 vga_arbiter loop5 ram5 tty1 tty37 tty7 zero And here is my fstab file: austin@austinvpn:/proc/scsi$ cat /etc/fstab # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed.

  • SQL SERVER – Introduction to Big Data – Guest Post

    - by pinaldave
    BIG Data – such a big word – everybody talks about this now a days. It is the word in the database world. In one of the conversation I asked my friend Jasjeet Sigh the same question – what is Big Data? He instantly came up with a very effective write-up.  Jasjeet is working as a Technical Manager with Koenig Solutions. He leads the SQL domain, and holds rich IT industry experience. Talking about Koenig, it is a 19 year old IT training company that offers several certification choices. Some of its courses include SharePoint Training, Project Management certifications, Microsoft Trainings, Business Intelligence programs, Web Design and Development courses etc. Big Data, as the name suggests, is about data that is BIG in nature. The data is BIG in terms of size, and it is difficult to manage such enormous data with relational database management systems that are quite popular these days. Big Data is not just about being large in size, it is also about the variety of the data that differs in form or type. Some examples of Big Data are given below : Scientific data related to weather and atmosphere, Genetics etc Data collected by various medical procedures, such as Radiology, CT scan, MRI etc Data related to Global Positioning System Pictures and Videos Radio Frequency Data Data that may vary very rapidly like stock exchange information Apart from difficulties in managing and storing such data, it is difficult to query, analyze and visualize it. The characteristics of Big Data can be defined by four Vs: Volume: It simply means a large volume of data that may span Petabyte, Exabyte and so on. However it also depends organization to organization that what volume of data they consider as Big Data. Variety: As discussed above, Big Data is not limited to relational information or structured Data. It can also include unstructured data like pictures, videos, text, audio etc. Velocity:  Velocity means the speed by which data changes. The higher is the velocity, the more efficient should be the system to capture and analyze the data. Missing any important point may lead to wrong analysis or may even result in loss. Veracity: It has been recently added as the fourth V, and generally means truthfulness or adherence to the truth. In terms of Big Data, it is more of a challenge than a characteristic. It is difficult to ascertain the truth out of the enormous amount of data and the one that has high velocity. There are always chances of having un-precise and uncertain data. It is a challenging task to clean such data before it is analyzed. Big Data can be considered as the next big thing in the IT sector in terms of innovation and development. If appropriate technologies are developed to analyze and use the information, it can be the driving force for almost all industrial segments. These include Retail, Manufacturing, Service, Finance, Healthcare etc. This will help them to automate business decisions, increase productivity, and innovate and develop new products. Thanks Jasjeet Singh for an excellent write up.  Jasjeet Sign is working as a Technical Manager with Koenig Solutions.

  • How to detect UTF-8-based encoded strings [closed]

    - by Diego Sendra
    A customer of asked us to build him a multi-language based support VB6 scraper, for which we had the need to detect UTF-8 based encoded strings to decode it later for proper displaying in application UI. It's necessary to point out that this need arises based on VB6 limitations to natively support UTF-8 in its controls, contrary to what it happens in .NET where you can tell a control that it should expect UTF-8 encoding. VB6 natively supports ISO 8859-1 and/or Windows-1252 encodings only, for which textboxes, dropdowns, listview controls, others can't be defined to natively support/expect UTF-8 as you can do in .NET considering what we just explained; so we would see weird symbols such as é, è among others, making it a whole mess at the time of displaying. So, next function contains whole UTF-8 encoded punctuation marks and symbols from languages like Spanish, Italian, German, Portuguese, French and others, based on an excellent UTF-8 based list we got from this link - Ref. http://home.telfort.nl/~t876506/utf8tbl.html Basically, the function compares if each and one of the listed UTF-8 encoded sentences, separated by | (pipe) are found in our passed string making a substring search first. Whether it's not found, it makes an alternative ASCII value based search to get a match. Say, a string like "Societé" (Society in english) would return FALSE through calling isUTF8("Societé") while it would return TRUE when calling isUTF8("SocietÈ") since È is the UTF-8 encoded representation of é. Once you got it TRUE or FALSE, you can decode the string through DecodeUTF8() function for properly displaying it, a function we found somewhere else time ago and also included in this post. Function isUTF8(ByVal ptstr As String) Dim tUTFencoded As String Dim tUTFencodedaux Dim tUTFencodedASCII As String Dim ptstrASCII As String Dim iaux, iaux2 As Integer Dim ffound As Boolean ffound = False ptstrASCII = "" For iaux = 1 To Len(ptstr) ptstrASCII = ptstrASCII & Asc(Mid(ptstr, iaux, 1)) & "|" Next tUTFencoded = "Ä|Ã…|Ç|É|Ñ|Ö|ÃŒ|á|Ã|â|ä|ã|Ã¥|ç|é|è|ê|ë|í|ì|î|ï|ñ|ó|ò|ô|ö|õ|ú|ù|û|ü|â€|°|¢|£|§|•|¶|ß|®|©|â„¢|´|¨|â‰|Æ|Ø|∞|±|≤|≥|Â¥|µ|∂|∑|âˆ|Ï€|∫|ª|º|Ω|æ|ø|¿|¡|¬|√|Æ’|≈|∆|«|»|…|Â|À|Ã|Õ|Å’|Å“|–|—|“|â€|‘|’|÷|â—Š|ÿ|Ÿ|â„|€|‹|›|ï¬|fl|‡|·|‚|„|‰|Â|Ú|Ã|Ë|È|Ã|ÃŽ|Ã|ÃŒ|Ó|Ô||Ã’|Ú|Û|Ù|ı|ˆ|Ëœ|¯|˘|Ë™|Ëš|¸|Ë|Ë›|ˇ" & _ "Å|Å¡|¦|²|³|¹|¼|½|¾|Ã|×|Ã|Þ|ð|ý|þ" & _ "â‰|∞|≤|≥|∂|∑|âˆ|Ï€|∫|Ω|√|≈|∆|â—Š|â„|ï¬|fl||ı|˘|Ë™|Ëš|Ë|Ë›|ˇ" tUTFencodedaux = Split(tUTFencoded, "|") If UBound(tUTFencodedaux) > 0 Then iaux = 0 Do While Not ffound And Not iaux > UBound(tUTFencodedaux) If InStr(1, ptstr, tUTFencodedaux(iaux), vbTextCompare) > 0 Then ffound = True End If If Not ffound Then 'ASCII numeric search tUTFencodedASCII = "" For iaux2 = 1 To Len(tUTFencodedaux(iaux)) 'gets ASCII numeric sequence tUTFencodedASCII = tUTFencodedASCII & Asc(Mid(tUTFencodedaux(iaux), iaux2, 1)) & "|" Next 'tUTFencodedASCII = Left(tUTFencodedASCII, Len(tUTFencodedASCII) - 1) 'compares numeric sequences If InStr(1, ptstrASCII, tUTFencodedASCII) > 0 Then ffound = True End If End If iaux = iaux + 1 Loop End If isUTF8 = ffound End Function Function DecodeUTF8(s) Dim i Dim c Dim n s = s & " " i = 1 Do While i <= Len(s) c = Asc(Mid(s, i, 1)) If c And &H80 Then n = 1 Do While i + n < Len(s) If (Asc(Mid(s, i + n, 1)) And &HC0) <> &H80 Then Exit Do End If n = n + 1 Loop If n = 2 And ((c And &HE0) = &HC0) Then c = Asc(Mid(s, i + 1, 1)) + &H40 * (c And &H1) Else c = 191 End If s = Left(s, i - 1) + Chr(c) + Mid(s, i + n) End If i = i + 1 Loop DecodeUTF8 = s End Function

  • Thoughts on Thoughts on TDD

    Brian Harry wrote a post entitled Thoughts on TDD that I thought I was going to let lie, but I find that I need to write a response. I find myself in agreement with Brian on many points in the post, but I disagree with his conclusion. Not surprisingly, I agree with the things that he likes about TDD. Focusing on the usage rather than the implementation is really important, and this is important whether you use TDD or not. And YAGNI was a big theme in my Seven Deadly Sins of Programming series. Now, on to what he doesnt like. He says that he finds it inefficient to have tests that he has to change every time he refactors. Here is where we part company. If you are having to do a lot of test rewriting (say, more than a couple of minutes work to get back to green) *often* when you are refactoring your code, I submit that either you are testing things that you dont need to test (internal details rather than external implementation), your code perhaps isnt as decoupled as it could be, or maybe you need a visit to refactorers anonymous. I also like to refactor like crazy, but as we all know, the huge downside of refactoring is that we often break things. Important things. Subtle things. Which makes refactoring risky. *Unless* we have a set of tests that have great coverage. And TDD (or Example-based Design, which I prefer as a term) gives those to us. Now, I dont know what sort of coverage Brian gets with the unit tests that he writes, but I do know that for the majority of the developers Ive worked with and I count myself in that bucket the coverage of unit tests written afterwards is considerably inferior to the coverage of unit tests that come from TDD. For me, it all comes down to the answer to the following question: How do you ensure that your code works now and will continue to work in the future? Im willing to put up with a little efficiency on the front side to get that benefit later. Its not the writing of the code thats the expensive part, its everything else that comes after. I dont think that stepping through test cases in the debugger gets you what you want. You can verify what the current behavior is, sure, and do it fairly cheaply, but you dont help the guy in the future who doesnt know what conditions were important if he has to change your code. His second part that he doesnt like backing into an architecture (go read to see what he means). Ive certainly had to work with code that was like this before, and its a nightmare the code that nobody wants to touch. But thats not at all the kind of code that you get with TDD, because if youre doing it right youre doing the write a failing tests, make it pass, refactor approach. Now, you may miss some useful refactorings and generalizations for this, but if you do, you can refactor later because you have the tests that make it safe to do so, and your code tends to be easy to refactor because the same things that make code easy to write unit tests for make it easy to refactor. I also think Brian is missing an important point. We arent all as smart as he is. Im reminded a bit of the lesson of Intentional Programming, Charles Simonyis paradigm for making programming easier. I played around with Intentional Programming when it was young, and came to the conclusion that it was a pretty good thing if you were as smart as Simonyi is, but it was pretty much a disaster if you were an average developer. In this case, TDD gives you a way to work your way into a good, flexible, and functional architecture when you dont have somebody of Brians talents to help you out. And thats a good thing.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.
