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

    - by [email protected]
    By ken.pulverman on March 24, 2010 8:51 AM ERP has been the backbone of enterprise software. The data held in your ERP system is core of most companies. Efficiencies gained through the accounting and resource allocation through ERP software have literally saved companies trillions of dollars. Not only does everything seem to be fine with your ERP system, you haven't had to touch it in years. Why aren't you ready for what comes next? Well judging by the growth rates in the space (Oracle posted only a 3% growth rate, while SAP showed a 12% decline) there hasn't been much modernization going on, just a little replacement activity. If you are like most companies, your ERP system is connected to a proprietary middleware solution that only effectively talks with a handful of other systems you might have acquired from the same vendor. Connecting your legacy system through proprietary middleware is expensive and brittle and if you are like most companies, you were only willing to pay an SI so much before you said "enough." So your ERP is working. It's humming along. You might not be able to get Order to Promise information when you take orders in your call center, but there are work arounds that work just fine. So what's the problem? The problem is that you built your business around your ERP core, and now there is such pressure to innovate your business processes to keep up that you need a whole new slew of modern apps and you need ERP data to be accessible from everywhere. Every time you change a sales territory or a comp plan or change a benefits provider your ERP system, literally the economic brain of your business, needs to know what's going on. And this giant need to access and provide information to your ERP is only growing. What makes matters even more challenging is that apps today come in every flavor under the Sun™. SaaS, cloud, managed, hybrid, outsourced, composite....and they all have different integration protocols. The only easy way to get ahead of all this is to modernize the way you connect and run your applications. Unlike the middleware solutions of yesteryear, modern middleware is effectively the operating system of the enterprise. In the same way that you rely on Apple, Microsoft, and Google to find a video driver for your 23" monitor or to ensure that Word or Keynote runs, modern middleware takes care of intra-application connectivity and process execution. It effectively allows you to take ERP out of the middle while ensuring connectivity to your vital data for anything you want to do. The diagram below reflects that change. In this model, the hegemony of ERP is over. It too has to become a stealthy modern app to help you quickly adapt to business changes while managing vital information. And through modern middleware it will connect to everything. So yes ERP as we've know it is dead, but long live ERP as a connected application member of the modern enterprise. I want to Thank Andrew Zoldan, Group Vice President Oracle Manufacturing Industries Business Unit for introducing me to how some of his biggest customers have benefited by modernizing their applications infrastructure and making ERP a connected application. by John Burke, Group Vice President, Applications Business Unit

To help carriers better prepare for what lies ahead LOMA's Resource Magazine asked Karen Furtado, partner of Strategy Meets Action, to help them chart a course in Navigating Policy Administration Selection, the cover story of this month’s issue. The industry analyst and research firm recently asked insurance carriers to name the business drivers for replacing legacy policy administration systems. The top five cited, according to Furtado, centered on: Supporting growth in current lines Improving competitive position Containing and reducing costs Supporting growth in new lines Supporting agent demands and interaction It’s no surprise that fueling growth, both now and in the future, continues to be a key driver for modernization. Why? Inflexible, hard-coded, legacy systems require customization by IT every time a change is required. This in turn impedes a carrier’s ability to be agile, constraining their ability to quickly adapt to changing regulatory requirements and evolving market demands. It also stymies their ability to quickly bring to market new products or rapidly configure changes to existing ones, and also can inhibit how carriers service customers and distribution channels. In the article, Furtado advised carriers to ensure that the policy administration system they are considering is current and modern, with an adaptable user interface and flexible service-oriented architecture. She said carriers to should ask themselves, “How much do you need flexibility and agility now and in the future? Does it support the business processes and rules that are needed for you to be able to create that adaptable environment?” Furtado went on to advise that carriers “Connect your strategy to your business and technical capabilities before you make investment choices…You want to enable your organization to transform for the future, not just automate the past.” Unlocking High Performance with Policy Administration Transformation also was the topic of a recent LOMA webcast moderated by Ron Clark, editor of LOMA's Resource Magazine. The web cast, which featured speakers from Oracle Insurance and Capgemini, focused on how insurers can competitively drive high performance by: Replacing a legacy policy administration system with a modern, flexible platform Optimizing IT and operations costs, creating consistent processes and eliminating resource redundancies Selecting the right partner with the best blend of technology, operational, and consulting capabilities to achieve market leadership Understanding the value of outsourcing closed block operations Learn more by clicking here to access this free, one-hour recorded webcast.

  • E-Business Suite 12.1.3 Data Masking Certified with Enterprise Manager 12c

    - by Elke Phelps (Oracle Development)
    Following up on our prior announcement for EM 11g, we're pleased to announce the certification of the E-Business Suite 12.1.3 Data Masking Template for the Data Masking Pack with Enterprise Manager Cloud Control 12c. You can use the Oracle Data Masking Pack with Oracle Enterprise Manager Grid Control 12c to scramble sensitive data in cloned E-Business Suite environments.  Due to data dependencies, scrambling E-Business Suite data is not a trivial task.  The data needs to be scrubbed in such a way that allows the application to continue to function.  You may scramble data in E-Business Suite cloned environments with EM12c using the following template: E-Business Suite 12.1.3 Data Masking Template for Data Masking Pack with EM12c (Patch 14407414) What does data masking do in E-Business Suite environments? Application data masking does the following: De-identify the data:  Scramble identifiers of individuals, also known as personally identifiable information or PII.  Examples include information such as name, account, address, location, and driver's license number. Mask sensitive data:  Mask data that, if associated with personally identifiable information (PII), would cause privacy concerns.  Examples include compensation, health and employment information.   Maintain data validity:  Provide a fully functional application. How can EBS customers use data masking? The Oracle E-Business Suite Template for Data Masking Pack can be used in situations where confidential or regulated data needs to be shared with other non-production users who need access to some of the original data, but not necessarily every table.  Examples of non-production users include internal application developers or external business partners such as offshore testing companies, suppliers or customers.  The template works with the Oracle Data Masking Pack and Oracle Enterprise Manager to obscure sensitive E-Business Suite information that is copied from production to non-production environments. The Oracle E-Business Suite Template for Data Masking Pack is applied to a non-production environment with the Enterprise Manager Grid Control Data Masking Pack.  When applied, the Oracle E-Business Suite Template for Data Masking Pack will create an irreversibly scrambled version of your production database for development and testing.  What's new with EM 12c? Some of the execution steps may also be performed with EM Command Line Interface (EM CLI).  Support of EM CLI is a new feature with the E-Business Suite Release 12.1.3 template for EM 12c.  Is there a charge for this? Yes. You must purchase licenses for the Oracle Data Masking Pack plug-in. The Oracle E-Business Suite 12.1.3 Template for the Data Masking Pack is included with the Oracle Data Masking Pack license.  You can contact your Oracle account manager for more details about licensing.

  • Ubuntu 12.04 - No sound - HELP!

    - by Bruno Tacca
    I'm panicking... my sound stopped working after I tried to set-up my notebook speakers, plus two headphone jacks... My idea was to multichannel the sound to 3 channels, built-in speakers, and sound-card 2 headphone jacks. After a couple efforts I did it with 2 channels, speakers and 1 headphone jack, but the other wasn't working. After more tries and tries, sound stop working. I just want my sound back... crying like a baby on the floor. And, if possible, but not necessary, a simple guide to active the 3 channels. xD I will post the diagnosis according to https://help.ubuntu.com/community/SoundTroubleshootingProcedure STEP 1 Did it, still no sound. STEP 2 Did it, still no sound. STEP 3 and #STEP 4 (I removed the log cause there is a limit of characters to be posted.) The log can be found here: https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/238653 STEP 5 Rebooted, still no sound. STEP 6 Did it. In the Output Devices tab, nothing is muted. I play a music with the Rhythmbox Music Player, I don't hear anything but in the pavucontrol I can see in the Built-in Audio Analog Stereo a sound bar shaking... but, no sound. STEP 7 In alsamixer, AlsaMixer v1.0.25 Card: HDA Intel PCH Chip: Creative CA0132 information View: F3:[Playback] F4: Capture F5: All Item: Headphone [dB gain: 25.00, 25.00] Then, I have 5 columns Headphone, Speaker, PCM, S/PDIF, S/PDIF Default PCM A little weird when I try to mute the Headphone and the Speaker, here what happens: Starting both unmutted, mutting headphone cause speaker being mutted automaticaly. Starting both unmutted, mutting speaker cause headphone being mutted automaticaly. Starting both mutted, possible to unmute both separately. STEP 8 I cannot hear sound on both (headphone and/or speaker). STEP 9 Dual boot... Restarted, windows was with sound at max volume. Restarted again, still no sound at ubuntu. I heard something when ubuntu started, a little noise, then silence again. The sound icon always start mutted, after unmutting, I have no sound. STEP 10 I dont have this command in my ubuntu. STEP 11 Tried at STEP 8, no sound. There are no problem with jumpers or hardware, cause I have sound working on windows. STEP 12 No way to open my alienware and loss the warranty x.X" STEP 13 I think it's loaded, judging my the logs STEP 14 Alienware M17xR4, the hardware is listed in the logs above, at STEP 4. There are two headphone hacks, one with just an headphone printed above, and the other with an headset (with mic) printed, there is a mic jack too, and a spdif (optical) too. STEP 15 I dont want to enable S/PDIF STEP 16 I never used the HDMI output, yet... Thanks in advance. I hope I listed all the information you need.

  • Guessing Excel Data Types

    - by AjarnMark
    Note to Self HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0\Engines\Excel: TypeGuessRows = 0 means scan everything. Note to Others About 10 years ago I stumbled across this bit of information just when I needed it and it saved my project.  Then for some reason, a few years later when it would have been nice, but not critical, for some reason I could not find it again anywhere.  Well, now I have stumbled across it again, and to preserve my future self from nightmares and sudden baldness due to pulling my hair out, I have decided to blog it in the hopes that I can find it again this way. Here’s the story…  When you query data from an Excel spreadsheet, such as with old-fashioned DTS packages in SQL 2000 (my first reference) or simply with an OLEDB Data Adapter from ASP.NET (recent task) and if you are using the Microsoft Jet 4.0 driver (newer ones may deal with this differently) then you can get funny results where the query reports back that a cell value is null even when you know it contains data. What happens is that Excel doesn’t really have data types.  While you can format information in cells to appear like certain data types (e.g. Date, Time, Decimal, Text, etc.) that is not really defining the cell as being of a certain type like we think of when working with databases.  But, presumably, to make things more convenient for the user (programmer) when you issue a query against Excel, the query processor tries to guess what type of data is contained in each column and returns it in an appropriate manner.  This is all well and good IF your data is consistent in every row and matches what the processor guessed.  And, for efficiency’s sake, when the query processor is trying to figure out each column’s data type, it does so by analyzing only the first 8 rows of data (default setting). Now here’s the problem, suppose that your spreadsheet contains information about clothing, and one of the columns is Size.  Now suppose that in the first 8 rows, all of your sizes look like 32, 34, 18, 10, and so on, using numbers, but then, somewhere after the 8th row, you have some rows with sizes like S, M, L, XL.  What happens is that by examining only the first 8 rows, the query processor inferred that the column contained numerical data, and then when it hits the non-numerical data in later rows, it comes back blank.  Major bummer, and a real pain to track down if you don’t know that Excel is doing this, because you study the spreadsheet and say, “the data is RIGHT THERE!  WHY doesn’t the query see it?!?!”  And the hair-pulling begins. So, what’s a developer to do?  One option is to go to the registry setting noted above and change the DWORD value of TypeGuessRows from the default of 8 to 0 (zero).  Setting this value to zero will force Jet to scan every row in the spreadsheet before making its determination as to what type of data the column contains.  And that means that in the example above, it would have treated the column as a string rather than as numeric, and presto! your query now returns all of the values that you know are in there. Of course, there is a caveat… if you are querying large spreadsheets, making Jet scan every row can be quite a performance hit.  You could enter a different number (more than 8) that you believe is a better sampling of rows to make the guess, but you still have the possibility that every row scanned looks alike, but that later rows are different, and that you might get blanks when there really is data there.  That’s the type of gamble, I really don’t like to take with my data. Anyone with a better approach, or with experience with more recent drivers that have a better way of handling data types, please chime in!

  • SQLAuthority News – Getting Ready to Learn SQL Server

    - by pinaldave
    If you have read my earlier blog post you must be aware of how I am always eager to learn new things. I have signed up for three days learning course at Koenig Solutions for End to End SQL Server Business Intelligence. You may wonder why I sign up for the course on SQL Server when it seems that I know a lot about it. Well, the belief is incorrect that I know a lot. I think there are plenty of things which I have been dreaming to learn. Why am I learning SQL Server? First of all – I do not know everything and second it is always a good idea to learn more. No matter how old we get or how much we think we know – there are always details which we can learn and refresh few concepts. Learning is never ending process philosophically but it is true as well in reality. SQL Server 2012 is already released earlier this year and there are plenty of enhancements released. Recently I was going over the list of the all the new feature and enhancement and I realized that there few things about SQL Server 2008 R2 I never got a chance to have a hand’s on experience and we have entered into the era of SQL Server 2012. I feel a bit bad about it and I decided to make it a priority for me to learn all the missing experiences. Quick Action – Registration The very same day I called up my friend who owns Koenig Solution and expressed my concern and requested his help. During my early career when I was a SQL Server Trainer, we had some good synergy between us and now they are very successful offshore training company by having a physical location in Delhi,  Goa, Dahradun, Shimla, Goa and Bangalore. I quickly visited their Bangalore Center and paid my fees for learning SQL Server Business Intelligence course. Very next second I got call from my friend suggesting that I learn this course from Delhi instead of Bangalore. As per him I should travel to Delhi and learn the course how other students are learning “Away from Home”. This made sense as I stay in Bangalore and if I return home after a long day of learning, I will be not able to practice for the next day as there will be “sweet distraction” of the family. Well I opted for Delhi. What Registration Fees Included I learned from registration processes that the following were included in the fees. 3 meals every day (hearty breakfast, lunch from premium restaurants and home cooked like dinner) Airport pick up and drop Hotel Stay Internet at hotel and at learning institute Unlimited coffee and snacks at learning institute Printed Learning Material Certification Fees (if applicable) Learning material … And of course classroom training I thought registration process was over when I paid fees. Well, I was in for a very nice surprise. Registration Experience – Bliss! Within few hours I received emails from Center Manager of Delhi with all the necessary details I need to know about my learning experience. The email contained following information in detail and it blew me away. Details of the pick up from airport – driver information Details of Delhi and important information List of all the important people and emergency contact details Internet connection details Detail of the trainer and all the training details and lots of other relevant information Well so far everything looks great. Tomorrow I will reach to Delhi and I will share how things go on. Any suggestion for things to do in Delhi?

  • Orchestrating the Virtual Enterprise, Part II

    - by Kathryn Perry
    A guest post by Jon Chorley, Oracle's CSO & Vice President, SCM Product Strategy Almost everyone has ordered from Amazon.com at one time or another. Our orders are as likely to be fulfilled by third parties as they are by Amazon itself. To deliver the order promptly and efficiently, Amazon has to send it to the right fulfillment location and know the availability in that location. It needs to be able to track status of the fulfillment and deal with exceptions. As a virtual enterprise, Amazon's operations, using thousands of trading partners, requires a very different approach to fulfillment than the traditional 'take an order and ship it from your own warehouse' model. Amazon had no choice but to develop a complex, expensive and custom solution to tackle this problem as there used to be no product solution available. Now, other companies who want to follow similar models have a better off-the-shelf choice -- Oracle Distributed Order Orchestration (DOO).  Consider how another of our customers is using our distributed orchestration solution. This major airplane manufacturer has a highly complex business and interacts regularly with the U.S. Government and major airlines. It sits in the middle of an intricate supply chain and needed to improve visibility across its many different entities. Oracle Fusion DOO gives the company an orchestration mechanism so it could improve quality, speed, flexibility, and consistency without requiring an organ transplant of these highly complex legacy systems. Many retailers face the challenge of dealing with brick and mortar, Web, and reseller channels. They all need to be knitted together into a virtual enterprise experience that is consistent for their customers. When a large U.K. grocer with a strong brick and mortar retail operation added an online business, they turned to Oracle Fusion DOO to bring these entities together. Disturbing the Peace with Acquisitions Quite often a company's ERP system is disrupted when it acquires a new company. An acquisition can inject a new set of processes and systems -- or even introduce an entirely new business like Sun's hardware did at Oracle. This challenge has been a driver for some of our DOO customers. A large power management company is using Oracle Fusion DOO to provide the flexibility to rapidly integrate additional products and services into its central fulfillment operation. The Flip Side of Fulfillment Meanwhile, we haven't ignored similar challenges on the supply side of the equation. Specifically, how to manage complex supply in a flexible way when there are multiple trading parties involved? How to manage the supply to suppliers? How to manage critical components that need to merge in a tier two or tier three supply chain? By investing in supply orchestration solutions for the virtual enterprise, we plan to give users better visibility into their network of suppliers to help them drive down costs. We also think this technology and full orchestration process can be applied to the financial side of organizations. An example is transactions that flow through complex internal structures to minimize tax exposure. We can help companies manage those transactions effectively by thinking about the internal organization as a virtual enterprise and bringing the same solution set to this internal challenge.  The Clear Front Runner No other company is investing in solving the virtual enterprise supply chain issues like Oracle is. Oracle is in a unique position to become the gold standard in this market space. We have the infrastructure of Oracle technology. We already have an Oracle Fusion DOO application which embraces the best of what's required in this area. And we're absolutely committed to extending our Fusion solution to other use cases and delivering even more business value.

  • Ubuntu 12 crashed and took down network

    - by Leopd
    We recently set up a new Ubuntu 12.04LTS server on our network. It's not fully configured so it's not doing much beyond sshd and a default apache2 install. But this evening it appears to have crashed. It wasn't responding to the network or the keyboard. But the worst part is, it took down the entire network. My knowledge of the network stack below OSI layer 3 is very limited, so the rest confuses me. When this machine was physically connected to the network, no other machine could connect to the outside internet. When things were broken, running arp showed that our gateway's IP address (10.0.1.1) was listed as "invalid." Unplugging the server from the network fixed the problem, and plugging it back in broke it again. So the crashed server was advertising itself as owning the gateway's IP address? There's nothing at all in syslog during the time when it was causing problems. Any ideas about how to figure out what went wrong or what we can do to prevent it from happening again?

  • Tweaking Remote Control (In-Kernel LIRC)

    - by Geoff
    I've recently rebuilt my MythTV box using Mythbuntu 12.04, to take advantage of newer hardware (Ivy Bridge). On my previous build I used lirc to manage the remote, i.e. the mapping of key codes - keypresses - application keys; it was quite a journey to learn it all, and I ended up fairly comfortable with how it all worked. What I have: I have a cheap Chinavasion remote and USB dongle, which I've found several articles on; these largely revolve around working with XBMC (interesting, but I don't think directly applicable) and also around getting a Harmony remote to work (it's a Chinavasion CVSB-983 - very useful, since I needed this to get my Harmony 900 working). Mythbuntu 12.04 64-bit MythTV 0.25 (likely irrelevant) How it is right now When I plug this in, it 'just works'. Which is great, except that Ubuntu uses it natively, and prevents some of the button presses from getting through to Myth. For example, I can send a button from the remote that equates to Ctrl-Alt-A (which I assume Ubuntu isn't interested in), and then trap that in Mythfrontend, but the remote's Play button is caught by Ubuntu (which displays a large circle with a line though it, as there's no media player loaded). I understand that this is because lirc is merged into the kernel now, and I like that. What I've done so far: Found the device using lsusb: $ lsusb Bus 001 Device 004: ID 073a:2230 Chaplet Systems, Inc. infrared dongle for remote Found the event device number: $ cat /proc/bus/input/devices I: Bus=0003 Vendor=073a Product=2230 Version=0110 N: Name="HID 073a:2230" P: Phys=usb-0000:00:1a.0-1.2/input0 S: Sysfs=/devices/pci0000:00/0000:00:1a.0/usb1/1-1/1-1.2/1-1.2:1.0/input/input5 U: Uniq= H: Handlers=sysrq kbd mouse1 event5 js0 B: PROP=0 B: EV=10001f B: KEY=4c37fff072ff32d bf54445600000000 ffffffffff 30c100b17c007 ffa67bfad951dfff febeffdfffefffff fffffffffffffffe B: REL=343 B: ABS=100030000 B: MSC=10 Tested the input with evtest (I pressed Play): $ sudo evtest /dev/input/event5 Input driver version is 1.0.1 Input device ID: bus 0x3 vendor 0x73a product 0x2230 version 0x110 Input device name: "HID 073a:2230" Supported events: Event type 0 (EV_SYN) Event type 1 (EV_KEY) Event code 1 (KEY_ESC) Event code 2 (KEY_1) Event code 3 (KEY_2) Event code 4 (KEY_3) Event code 5 (KEY_4) Event code 6 (KEY_5) Event code 7 (KEY_6) <------------snipped lots of 'Event code' lines------------> Testing ...

I'd like to either remap each button press to something that Ubuntu/Unity will ignore, or even better pass the keypress directly to Myth (I suspect this later is only possible with lirc, but I could be wrong). I would really like to do this with the in-kernel drivers, i.e. without explicitly loading lirc; if that's the way the world is going, I'd rather find a way to map the current behaviour to what I want, rather than forcing the 'old' arrangement of loading lirc outside the kernel. Learning something new is also worthwhile! My guess: I'm assuming that this will require using setkeycodes, but have had trouble finding enough information to configure this. Any help greatly appreciated!

  • Create and Track Your Own License Keys with PowerShell

    - by BuckWoody
    SQL Server used to have  cool little tool that would let you track your licenses. Microsoft didn’t use it to limit your system or anything, it was just a place on the server where you could put that this system used this license key. I miss those days – we don’t track that any more, and I want to make sure I’m up to date on my licensing, so I made my own. Now, there are a LOT of ways you could do this. You could add an extended property in SQL Server, add a table to a tracking database, use a text file, track it somewhere else, whatever. This is just the route I chose; if you want to use some other method, feel free. Just sharing here. Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. And this is REALLY important. I include a disclaimer at the end of my scripts, but in this case you’re modifying your registry, and that could be EXTREMELY dangerous – only do this on a test server – and I’m just showing you how I did mine. It isn’t an endorsement or anything like that, and this is a “Buck Woody” thing, NOT a Microsoft thing. See this link first, and then you can read on. OK, here’s my script: # Track your own licenses # Write a New Key to be the License Location mkdir HKCU:\SOFTWARE\Buck   # Write the variables - one sets the type, the other sets the number, and the last one holds the key New-ItemProperty HKCU:\SOFTWARE\Buck -name "SQLServerLicenseType" -value "Processor" # Notice the Dword value here - this one is a number so it needs that. Keep this on one line! New-ItemProperty HKCU:\SOFTWARE\Buck -name "SQLServerLicenseNumber" -propertytype DWord -value 4 New-ItemProperty HKCU:\SOFTWARE\Buck -name "SQLServerLicenseKey" -value "ABCD1234"   # Read them all $LicenseKey = Get-Item HKCU:\Software\Buck $Licenses = Get-ItemProperty $LicenseKey.PSPath foreach ($License in $LicenseKey.Property) { $License + "=" + $Licenses.$License }   Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system. Yes, there are always multiple ways to do things, and this script may not work in every situation, for everything. It’s just a script, people.

I also added the last four lines. Anyway, what can I add to this so that I don't have to reconfigure them each time I restart? Currently, I have to open Sound Settings, then under the hardware tab, select Analog Stereo Output, and then unplug my USB speakers and plug them back in. This makes them pop up so that I can see them. Otherwise, it will not show my Z-5 speakers as a device that can be configured.

  • Getting Started with StreamInsight 2.1

    - by Roman Schindlauer
    If you're just beginning to get familiar with StreamInsight, you may be looking for a way to get started. What are the basics? How can I get my first StreamInsight application running so I can see how it works? Where is the 'front door' that will get me going? If that describes you, then this blog entry might be just what you need. If you're already a StreamInsight wiz, keep reading anyway - you may find some helpful links here that you weren't aware of. But here's what we'd like from you experienced readers in particular: if you know of other good resources that we missed, please feel free to add them in the comments below. We appreciate you sharing your expertise. The Book The basic documentation for StreamInsight is located in the MSDN Library (Microsoft StreamInsight 2.1). You'll notice that previous versions of StreamInsight are still there (1.2 and 2.0), but if you're just getting started you can stick to the 2.1 section. The documentation has been organized to function as reference material, which is fine after you're familiar with the technology. But if you're trying to learn the basics, you might want to take a different path instead of just starting at the top. The following is one map you can use. What Is StreamInsight? Here is a sequence of topics that should give you a good overview of what StreamInsight is and how it works: Overview answers the question, "what is it?" StreamInsight Server Architecture gives you a quick look at a high-level architectural drawing StreamInsight Concepts lays out an overview of the basic components Deploying StreamInsight Entities to a StreamInsight Server describes the mechanics of how these components work together Getting an Example Running Once you have this background, go ahead and install StreamInsight and get a basic example up and running: Installation download and install the software StreamInsight Examples walk through a set of 3 simple StreamInsight applications that work together to demonstrate what you learned in the topics above; you can copy and paste the code into Visual Studio, compile, and run That's it - you now have a real, functioning StreamInsight system! Now that you have a handle on the basics, you might want to start digging deeper. Digging Deeper Here's a suggested path through the documentation to help you understand the next layer of StreamInsight technologies: Using Event Sources and Event Sinks sources supply data and sinks consume it; this topic gives you an overview of how they work Publishing and Connecting to the StreamInsight Server practical details on how to set up a StreamInsight server A Hitchhiker’s Guide to StreamInsight 2.1 Queries queries are the heart of how StreamInsight performs data analytics, and this whitepaper will help you really understand how they work Using StreamInsight LINQ root through this section for technical details on specific query components Using the StreamInsight Event Flow Debugger in addition to troubleshooting, the debugger is a great way to learn more about what goes on inside a StreamInsight application And Even Deeper Finally, to get a handle on some of the more complex things you can do with StreamInsight, dig into these: Input and Output Adapters adapters can be useful for handling more complex sources and sinks Building Resilient StreamInsight Applications a resilient application is able to recover from system failures Operations this section will help you monitor and troubleshoot a running StreamInsight system The StreamInsight Community As you're designing and developing your StreamInsight solutions, you probably will find it helpful to see working examples or to learn tips and tricks from others.

  • Impressions of my ASUS eee slate EP121 - Dual core 4GB, 64GB SSD

    - by tonyrogerson
    This thing is lovely, very nice bluetooth keyboard that has nice feedback on the keypress, there is no mouse but you can use the stylus or get yourself a bluetooth mouse, me, I've opted for a Microsoft ARC mouse which is a delight to use, the USB doors are a pain to open for the first time if like me you don't have any finger nails. It came as a suprise that the slate shows four processors, Dual Core with multi-threading, I didn't really look at the processor I was more interested in the amount of memory and the SSD; you don't get the full 4GB even with the 64 bit version of Windows 7 installed (which I immediately upgraded to Ultimate through my MSDN subscription). The box is extremely responsive - extremely, it loads Winword in literally a second. I've got office 2010 and onenote 2010 on there now; one problem is that on applying all (43) windows updates since the upgrade the machine is still sat on step 3 of 3 on the start up configuring updates screen after about an hour, you can't turn this machine off without using a paper clip to reset it and as I have just found you need a paper clip :). Installing Windows 7 SP1 was effortless. One of the first things I did on it was to reduce the size of the font, by default its set at 125%, my eye sight is ok :) so I've set that back down. Amazon Kindle for the PC works really well, plenty of text on the screen when viewed portrait, the case it comes with also allows the slate to stand up in various positions - portrait, horizontal - seems stable enough. The wireless works well, seems to have a better signal than my other two laptop machines which is good news. The gadget passed the pose test at work :). I use offline files to keep a copy of all my work stuff locally, I'm not sure what it is, well, its probably my server but whenever I try and sync it runs for a couple of minutes then fails with network name no longer contactable, funnily enough its fine from my big laptop so I can only guess this may be a driver type issue on the EP121 itself - very odd and very annoying. I do a lot of presenting and need to plug into a VGA project because most sites that's all that is offered, the EP121 has a mini-hdmi output which is great except for this scenario, hdmi is digital, vga is analogue, you will struggle to find a cost effective solution, I found HDFury and also a device HP do, however, a better solution appears to be getting a USB graphics adapter for instance the one I've ordered is the ClimaxDigital USB 2.0 to DVI,VGA or HDMI Adaptor which gives everything I need - VGA and DVI output and great resolution as well - ok, so fingers crossed because I'm presenting next Wednesday in Edinburgh and not taking my 300kg lenovo w700 (I'm sure my back just sighed in relief) - it certainly works really well on my LED TV, the install was simple - it just works! One of the several reasons for buying this piece of kit was to use it on my LED TV to remote into my main machine to check stuff whilst sat in my living room, also to watch webcasts and lecture videos in comfort away from my office, because of the wireless speed and limitation I'm opting for a USB network adapter from Belkin - that will also allow me to take advantage of my home gigabit network, there are only 2 usb ports on the slate so I'm going to knock up a hub so connecting it in is straight forward and simple, I'm also going to purchase a second power supply so I don't have to faff about with that either.I now have the developer x64 edition of SQL Server 2008 R2, yes everything :) - about 16GB left to play with on the machine now but that will be fine, I'll put AdventureWorks on there so I can play and demo stuff which is all I'm after from this, my development machine is significantly more powerful and meets my storage needs too.Travel test this weekend and next week, I'm in Dundee for my final exam for the masters degree.

  • Free RAM disappears - Memory leak?

    - by Izzy
    On a fresh started system, free reports about 1.5G used RAM (8G RAM alltogether, Ubuntu 12.04 with lightdm and plasma desktop, one konsole window started). Having the apps running I use, it still consumes not more than 2G. However, having the system running for a couple of days, more and more of my free RAM disappears -- without showing up in the list of used apps: while smem --pie=name reports less than 20% used (and 80% being available), everything else says differently. free -m for example reports on about day 7: total used free shared buffers cached Mem: 7459 7013 446 0 178 997 -/+ buffers/cache: 5836 1623 Swap: 9536 296 9240 (so you can see, it's not the buffers or the cache). Today this finally ended with the system crashing completely: the windows manager being gone, apps "hanging in the air" (frameless) -- and a popup notifying me about "too many open files". Syslog reports: kernel: [856738.020829] VFS: file-max limit 752838 reached So I closed those applications I was able to close, and killed X using Ctrl-Alt-backspace. X tried to come up again after that with failsafeX, but was unable to do so as it could no longer detect its configuration. So I switched to a console using Ctrl-Alt-F2, captured all information I could think of (vmstat, free, smem, proc/meminfo, lsof, ps aux), and finally rebooted. X again came up with failsafeX; this time I told it to "recover from my backed-up configuration", then switched to a console and successfully used startx to bring up the graphical environment. I have no real clue to what is causing this issue -- though it must have to do either with X itself, or with some user processes running on X -- as after killing X, free -m output looked like this: total used free shared buffers cached Mem: 7459 2677 4781 0 62 419 -/+ buffers/cache: 2195 5263 Swap: 9536 59 9477 (~3.5GB being freed) -- to compare with the output after a fresh start: total used free shared buffers cached Mem: 7459 1483 5975 0 63 730 -/+ buffers/cache: 689 6769 Swap: 9536 0 9536 Two more helpful outputs are provided by memstat -u. Shortly before the crash: User Count Swap USS PSS RSS mail 1 0 200 207 616 whoopsie 1 764 740 817 2300 colord 1 3200 836 894 2156 root 62 70404 352996 382260 569920 izzy 80 177508 1465416 1519266 1851840 After having X killed: User Count Swap USS PSS RSS mail 1 0 184 188 356 izzy 1 1400 708 739 1080 whoopsie 1 848 668 826 1772 colord 1 3204 804 888 1728 root 62 54876 131708 149950 267860 And after a restart, back in X: User Count Swap USS PSS RSS mail 1 0 212 217 628 whoopsie 1 0 1536 1880 5096 colord 1 0 3740 4217 7936 root 54 0 148668 180911 345132 izzy 47 0 370928 437562 915056 Edit: Just added two graphs from my monitoring system. Interesting to see: everytime when there's a "jump" in memory consumption, CPU peaks as well. Just found this right now -- and it reminds me of another indicator pointing to X itself: Often when returning to my machine and unlocking the screen, I found something doing heavvy work on my CPU. Checking with top, it always turned out to be /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none. So after this long explanation, finally my questions: What could be the possible causes? How can I better identify involved processes/applications? What steps could be taken to avoid this behaviour -- short from rebooting the machine all X days? I was running 8.04 (Hardy) for about 5 years on my old machine, never having experienced the like (always more than 100 days uptime, before rebooting for e.g. kernel updates). This now is a complete new machine with a fresh install of 8.04. In case it matters, some specs: AMD A4-3400 APU with Radeon(tm) HD Graphics, using the open-source ati/radeon driver (so no fglrx installed), 8GB RAM, WDC WD1002FAEX-0 hdd (1TB), Asus F1A75-V Evo mainboard. Ubuntu 12.04 64-bit with KDE4/Plasma. Apps usually open more or less permanently include Evolution, Firefox, konsole (with Midnight Commander running inside, about 4 tabs), and LibreOffice -- plus occasionally Calibre, Gimp and Moneyplex (banking software I'm already using for almost 20 years now, in a version which did fine on Hardy).

  • Ubuntu 13.04 installation issues: unable to handle kernel paging request error

    - by user173944
    I wish I could say that I’ve done more for the Linux community as of recent but I am very VERY new to all of this and I feel very much in over my head. I figured I would install Ubuntu. on my computer and then I would learn and contribute to the community simultaneously. I will try to be as detailed as I can, please ask questions if you need clarification. I installed Ubuntu. 13.04 (64-bit) on my dell Inspiron 1501. This has an AMD Turion 64-bit TL-56 1.8 Ghz mobile processor. It is a dual core. It has an ATI Radeon Xpress 1150 chipset in it as well. As of right now I only have a total of 2Ghz ram, however I was planning on upgrading that in the near future so I opted for the 64-bit Ubuntu. 13.04. I first tried the live CD and everything seemed to be functioning correctly other than the wireless (but that's not the issue at hand, there are plenty of guides on the internet on how to get that functioning). The internet worked just fine when it was plugged in so no issues there. However, once I went from that to installing 13.04 (just 13.04, no dual partitioning... I want this computer to run strictly Ubuntu.) it did not work. It took me into a shell that I could not type anything into. In this shell it said Bug: unable to handle kernel paging and then it called a bunch of traces and froze up. I had to hard reset the laptop. I tried the boot-repair program multiple times with many different settings and typically after starting up the laptop would say something along the lines of recursive errors. will attempt to fix and then it would attempt to fix a couple of things, and then the computer would freeze up after the text said end trace... so I had to hard reset it again. I'm not an impatient person either, when I say it would freeze up it would be for a period of at least 15 minutes each time before I decided to hard reset. I attempted to install 12.10 on it instead and I got the same exact message, and when I ran boot-repair it did the same exact thing as before. I am currently in the process of running memtest64+ on the computer's memory, though I really don't believe that, nor any of the hardware is at fault due to the fact that it was still running windows vista perfectly when I had decided to switch over to Ubuntu. so far the memtest has came back just fine without any errors, but I’ve only been running it for approximately an hour. So this is the situation I’m in. I did notice when I was using the live disk that the video driver needed updated so I performed that, though I’m fairly certain that has nothing to do with this. I have also attempted (though I’m not certain that my attempt was successful in accomplishing what I had planned) to manually edit the grub settings by making acpi=0 along top of adding nomodeset to the boot commands. Like I said, I’m not sure I did that correctly though, but I’m fairly certain I did. If anyone needs any more information I will be more than happy to provide it, I will post back once I get the full results of the memtest. I very much appreciate any ideas anyone else has, I’ve been at this for a few days to no avail... thank you

  • Nec USB 3.0 controller drops connection - Ubuntu 12.04.1

    - by Tom
    I have some serious problems with Technaxx pci-e 302p card. It has uPD720200a NEC chip with 4020 firmware. BIOS recognises it. Sometimes it recognises devices and system mounts them and are functional for few minutes, other times they can't be mount and error occours. After fresh install card worked fine, but after kernel and firmware update it behaves as mentioned. Outputs: uname -a Linux asd-GA-MA770-UD3 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux lspci -vvv USB controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04) (prog-if 30 [XHCI]) Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 17 Region 0: Memory at fd8fe000 (64-bit, non-prefetchable) [size=8K] Capabilities: <access denied> Kernel driver in use: xhci_hcd lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 008 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 009 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 07d1:3c0a D-Link System DWA-140 RangeBooster N Adapter(rev.B2) [Ralink RT3072] Bus 005 Device 004: ID 1997:1221 Bus 005 Device 003: ID 15c2:003c SoundGraph Inc. lsmod Module Size Used by nls_iso8859_1 12713 0 nls_cp437 16991 0 vfat 17585 0 fat 61512 1 vfat vesafb 13844 1 saa7134_alsa 18602 1 rfcomm 47604 0 bnep 18281 2 bluetooth 180104 10 rfcomm,bnep tda827x 18182 1 snd_hda_codec_hdmi 32474 1 ir_lirc_codec 12859 0 lirc_dev 19204 1 ir_lirc_codec tda8290 22616 1 arc4 12529 2 snd_hda_codec_realtek 224173 1 ir_mce_kbd_decoder 12777 0 ir_sony_decoder 12510 0 ir_jvc_decoder 12507 0 tuner 27428 1 ir_rc6_decoder 12507 0 snd_hda_intel 33773 5 rt2800usb 22684 0 rt2800lib 58925 1 rt2800usb crc_ccitt 12667 1 rt2800lib rt2x00usb 20762 1 rt2800usb rt2x00lib 51144 3 rt2800usb,rt2800lib,rt2x00usb mac80211 506816 3 rt2800lib,rt2x00usb,rt2x00lib ir_rc5_decoder 12507 0 rc_avermedia_m135a 12526 0 rc_imon_pad 12505 0 ir_nec_decoder 12507 0 cfg80211 205544 2 rt2x00lib,mac80211 snd_hda_codec 127706 3 snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel snd_ctxfi 111202 2 snd_hwdep 13668 1 snd_hda_codec imon 32839 0 snd_pcm 97188 5 saa7134_alsa,snd_hda_codec_hdmi,snd_hda_intel,snd_hda_codec,snd_ctxfi snd_seq_midi 13324 0 saa7134 181851 1 saa7134_alsa videobuf_dma_sg 19354 2 saa7134_alsa,saa7134 snd_rawmidi 30748 1 snd_seq_midi snd_seq_midi_event 14899 1 snd_seq_midi joydev 17693 0 rc_core 26412 13 ir_lirc_codec,ir_mce_kbd_decoder,ir_sony_decoder,ir_jvc_decoder,ir_rc6_decoder,ir_rc5_decoder,rc_avermedia_m135a,rc_imon_pad,ir_nec_decoder,imon,saa7134 snd_seq 61896 2 snd_seq_midi,snd_seq_midi_event fglrx 3263886 101 videobuf_core 26390 2 saa7134,videobuf_dma_sg v4l2_common 16454 2 tuner,saa7134 videodev 98259 3 tuner,saa7134,v4l2_common sp5100_tco 13791 0 snd_timer 29990 2 snd_pcm,snd_seq snd_seq_device 14540 3 snd_seq_midi,snd_rawmidi,snd_seq snd 78855 28 saa7134_alsa,snd_hda_codec_hdmi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_ctxfi,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device v4l2_compat_ioctl32 17128 1 videodev tveeprom 21249 1 saa7134 i2c_piix4 13301 0 soundcore 15091 1 snd edac_core 53746 0 serio_raw 13211 0 snd_page_alloc 18529 3 snd_hda_intel,snd_ctxfi,snd_pcm edac_mce_amd 23709 0 wmi 19256 0 mac_hid 13253 0 ppdev 17113 0 parport_pc 32866 1 k10temp 13166 0 lp 17799 0 parport 46562 3 ppdev,parport_pc,lp usb_storage 49198 0 uas 18180 0 usbhid 47199 0 hid 99559 1 usbhid firewire_ohci 41000 0 firewire_core 63558 1 firewire_ohci crc_itu_t 12707 1 firewire_core floppy 70365 0 pata_atiixp 13204 2 r8169 62099 0 dmesg | tail after plugging to usb 3.0 port [ 834.871296] sd 9:0:0:0: rejecting I/O to offline device [ 834.871308] sd 9:0:0:0: rejecting I/O to offline device [ 834.871319] sd 9:0:0:0: rejecting I/O to offline device [ 834.871330] sd 9:0:0:0: rejecting I/O to offline device [ 834.871530] sd 9:0:0:0: [sdd] Unhandled error code [ 834.871536] sd 9:0:0:0: [sdd] Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK [ 834.871545] sd 9:0:0:0: [sdd] CDB: Read(10): 28 00 0e 8e 48 0a 00 00 3e 00 [ 834.871564] end_request: I/O error, dev sdd, sector 244205578 [ 834.875497] sd 8:0:0:1: Device offlined - not ready after error recovery [ 834.885339] usb 9-2: USB disconnect, device number 2 Are there any other outputs need for answering?

  • HOWTO Turn off SPARC T4 or Intel AES-NI crypto acceleration.

    - by darrenm
    Since we released hardware crypto acceleration for SPARC T4 and Intel AES-NI support we have had a common question come up: 'How do I test without the hardware crypto acceleration?'. Initially this came up just for development use so developers can do unit testing on a machine that has hardware offload but still cover the code paths for a machine that doesn't (our integration and release testing would run on all supported types of hardware anyway).  I've also seen it asked in a customer context too so that we can show that there is a performance gain from the hardware crypto acceleration, (not just the fact that SPARC T4 much faster performing processor than T3) and measure what it is for their application. With SPARC T2/T3 we could easily disable the hardware crypto offload by running 'cryptoadm disable provider=n2cp/0'.  We can't do that with SPARC T4 or with Intel AES-NI because in both of those classes of processor the encryption doesn't require a device driver instead it is unprivileged user land callable instructions. Turns out there is away to do this by using features of the Solaris runtime loader (ld.so.1). First I need to expose a little bit of implementation detail about how the Solaris Cryptographic Framework is implemented in Solaris 11.  One of the new Solaris 11 features of the linker/loader is the ability to have a single ELF object that has multiple different implementations of the same functions that are selected at runtime based on the capabilities of the machine.  The alternate to this is having the application coded to call getisax() and make the choice itself.  We use this functionality of the linker/loader when we build the userland libraries for the Solaris Cryptographic Framework (specifically libmd.so, and the unfortunately misnamed due to historical reasons libsoftcrypto.so) The Solaris linker/loader allows control of a lot of its functionality via environment variables, we can use that to control the version of the cryptographic functions we run.  To do this we simply export the LD_HWCAP environment variable with values that tell ld.so.1 to not select the HWCAP section matching certain features even if isainfo says they are present.  For SPARC T4 that would be: export LD_HWCAP="-aes -des -md5 -sha256 -sha512 -mont -mpul" and for Intel systems with AES-NI support: export LD_HWCAP="-aes" This will work for consumers of the Solaris Cryptographic Framework that use the Solaris PKCS#11 libraries or use libmd.so interfaces directly.  It also works for the Oracle DB and Java JCE.  However does not work for the default enabled OpenSSL "t4" or "aes-ni" engines (unfortunately) because they do explicit calls to getisax() themselves rather than using multiple ELF cap sections. However we can still use OpenSSL to demonstrate this by explicitly selecting "pkcs11" engine  using only a single process and thread.  $ openssl speed -engine pkcs11 -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 54170.81k 187416.00k 489725.70k 805445.63k 1018880.00k $ LD_HWCAP="-aes" openssl speed -engine pkcs11 -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 29376.37k 58328.13k 79031.55k 86738.26k 89191.77k We can clearly see the difference this makes in the case where AES offload to the SPARC T4 was disabled. The "t4" engine is faster than the pkcs11 one because there is less overhead (again on a SPARC T4-1 using only a single process/thread - using -multi you will get even bigger numbers). $ openssl speed -evp aes-128-cbc ... type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes aes-128-cbc 85526.61k 89298.84k 91970.30k 92662.78k 92842.67k Yet another cool feature of the Solaris linker/loader, thanks Rod and Ali. Note these above openssl speed output is not intended to show the actual performance of any particular benchmark just that there is a significant improvement from using hardware acceleration on SPARC T4. For cryptographic performance benchmarks see the http://blogs.oracle.com/BestPerf/ postings.

  • Slow wired internet connection on Realtek RTL8168-8111 (Rev 6)

    - by Mark
    I keep on seeing issues people are having with their wireless. I am having an issue with being wired into my router. I installed Ubuntu 11.10 the other day, on my custom PC. The motherboard I have installed on this PC is an ASUS P8H61-M. The issue I am having is with my speed. I have a dual boot, windows 7 and the new Ubuntu. On my Windows install I am getting test speeds from Speakeasy at 17Mbps and actual downloads around 2-3MB/s. With Ubuntu, I am getting test speeds from Speakeasy at 1.14Mbps and actual downloads around 60KB/s. I have disabled IPv6 and am no using GoogleDNS for my DNS, but it hasn't resolved the issue. I have scanned my router (WRT54GS Linksys) to disable IPv6 connections, and I am not seeing any option for that. I cannot figure out why I am getting such sluggish internet connection. Any help to resolve would be great! I performed an iconfig -a with these results: mark@Mark-ASUS:~$ ifconfig -a eth0 Link encap:Ethernet HWaddr f4:6d:04:d1:2c:4e inet addr:192.168.1.103 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::f66d:4ff:fed1:2c4e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:21888 errors:0 dropped:21888 overruns:0 frame:21888 TX packets:21068 errors:0 dropped:90 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:26348337 (26.3 MB) TX bytes:2217140 (2.2 MB) Interrupt:46 Base address:0xc000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:7 errors:0 dropped:0 overruns:0 frame:0 TX packets:7 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:952 (952.0 B) TX bytes:952 (952.0 B) My specs are: mark@Mark-ASUS:~$ sudo lspci -nn 04:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.

The other issue I am noticing is sometimes my connection disconnects all together, for about a minute, then it reconnects.

  • Very slow KVM in Ubuntu 12.04

    - by Guy Fawkes
    I use Ubuntu 12.04 64-bit and KVM, my CPU is Core i5 3.3 GHz and I have 8 GB of DDR3 RAM. I run Windows 7 in KVM and it's extremely slow. My co-worker use Debian on the same PC configuration and can run Windows 7 extremely fast! Where can be my problem? sudo cat /etc/libvirt/qemu/windows.xml <!-- WARNING: THIS IS AN AUTO-GENERATED FILE. CHANGES TO IT ARE LIKELY TO BE OVERWRITTEN AND LOST.

  • Controlling server configurations with IPS

    - by barts
    I recently received a customer question regarding how they best could control which packages and which versions were used on their production Solaris 11 servers.  They had considered pointing each server at its own software repository - a common initial approach.  A simpler method leverages one of dependency mechanisms we introduced with Solaris 11, but is not immediately obvious to most people. Typically, most internal IT departments qualify particular versions for production use.  What this customer wanted to do was insure that their operations staff only installed internally qualified versions of Solaris on their servers.  The easiest way of doing this is to leverage the 'incorporate' type of dependency in a small package defined for each server type.  From the reference " Packaging and Delivering Software With the Image Packaging System in Oracle® Solaris 11.1":  The incorporate dependency specifies that if the given package is installed, it must be at the given version, to the given version accuracy. For example, if the dependent FMRI has a version of 1.4.3, then no version less than 1.4.3 or greater than or equal to 1.4.4 satisfies the dependency. Version 1.4.3.7 does satisfy this example dependency. The common way to use incorporate dependencies is to put many of them in the same package to define a surface in the package version space that is compatible. Packages that contain such sets of incorporate dependencies are often called incorporations. Incorporations are typically used to define sets of software packages that are built together and are not separately versioned. The incorporate dependency is heavily used in Oracle Solaris to ensurethat compatible versions of software are installed together. An example incorporate dependency is: depend type=incorporate fmri=pkg:/driver/network/ethernet/[email protected],5.11-0.175.0.0.0.2.1 So, to make sure only qualified versions are installed on a server, create a package that will be installed on the machines to be controlled.  This package will contain an incorporate dependency on the "entire" package, which controls the various components used to be build Solaris.  Every time a new version of Solaris has been qualified for production use, create a new version of this package specifying the new version of "entire" that was qualified.  Once this new control package is available in the repositories configured on the production server, the pkg update command will update that system to the specified version.  Unless a new version of the control package is made available, pkg update will report that no updates are available since no version of the control package can be installed that satisfies the incorporate constraint. Note that if desired, the same package can be used to specify which packages must be present on the system by adding either "require" or "group" dependencies; the latter permits removal of some of the packages, the former does not.  More details on this can be found in either the section 5 pkg man page or the previously mentioned reference document. This technique of using package dependencies to constrain system configuration leverages the SAT solver which is at the heart of IPS, and is basic to how we package Solaris itself.

  • Ti Launchpad

    - by raysmithequip
    Just thought I would get a couple of notes up here for reference to anyone that is interested...it is now Feb 2011 and I have not been posting here enough to remember this blog. Back in Nov 2010 I ordered the Ti launchpad msp430, it is a little target board kit replete with a mini USB cable, two very inexpensive programmable mcu's and a couple of pin headers with a couple of led's on board, a spi connector some on board jumpers and two programmable micro switches....all for less than $5.00...INCLUDING SHIPPING!!....not bad when the ardruino's are running around 20.00 for the target board, atmega328 and cable off of eBay...I wont even mention the microchip pic right now.  Naw, for $5.00 the Ti launchpad kit is about the cheapest fun around...if-uns your a geek that is... Well, the launchpad was backordered for almost two months, came like Xmas eve in fact...I had almost forgotten it!! And really, it was way late and not my idea of an Xmas present for myself.  That would of been the web expressions 4 I bought a few weeks back.  With all the holidays, I did not even look at it till last week, in fact I passed the wrapped board around at my local ham club meeting during points of personal privilege....some oh's and ahhs but mostly duhs...I actually ordered it to avoid downloading the huge code compressor studio 4 (CCS) that was supposed to be included on the cd.  No cd.  I had already downloaded IAR  another programming IDE for these little micro bugs. In my spare time I toyed with IAR and the launchpad board but after about two days of playing delete the driver with windows I decided to just download CCS 4, the code limited version, and give that a shot......CCS 4, is a good rewrite from the earlier versions, it is based on Eclipse as an IDE and includes the drivers for the msp430 target board I received in the kit.  Once installed I quickly configured the debugger for the target chip which was already plugged into the dip socket at the factory, msp430G2131 from he drop down list and clicked ok...I was in!! The CCS4 is full of bells and whistles compared to the IAR, which I would of preferred for the simplicity.  But the code compressor studio really does have it all!!..the code limited version is free, and of all things will give you java script editor box.  The whole layout in debugger mode reminds me of any modern programmer IDE...I mean sure give me Tex anytime but you simply must admire all the boxes and options included in the GUI.  It was a simple matter to check the assembly code in the flash and ram memory that came preloaded for the launchpad kit.  Assembly.  I am right now looking for my old assembly textbooks...sure I remember how to use mov and add etc but a couple of the commands are a little more than vague anymore.  Still, these little mcu's are about 50 cents each and might just work in a couple of projects I have lined up for the near future.  I may document the code here.  Luckily, I plan to write the code in c++ for the main project but if it has to be assembly, no prob.  For reference, the program that came already on the 2131 in the kit was a temperature indicator that alternately flashed red and green leds and changed the intensity of either depending on whether the temp was rising or falling...neat.  Neat enough that it might be worthwhile banging out a little GUI in windows 7 to test the new user device system calls, maybe put a temp gauge widget up on the desktop...just to keep from getting bored.  If you see some assembly code on this blog, you know I was doing something with one of the many mcu's out there.....thats all for now, more to follow...a bit later, of course.

  • PowerShell: Read Excel to Create Inserts

    - by BuckWoody
    I’m writing a series of articles on how to migrate “departmental” data into SQL Server. I also hold workshops on the entire process – from discovering that the data exists to the modeling process and then how to design the Extract, Transform and Load (ETL) process. Finally I write about (and teach) a few methods on actually moving the data. One of those options is to use PowerShell. There are a lot of ways even with that choice, but the one I show is to read two columns from the spreadsheet and output statements that would insert the data using a stored procedure. Of course, you could re-write this as INSERT statements, out to a text file for bcp, or even use a database connection in the script to move the data directly from Excel into SQL Server. This snippet won’t run on your system, of course – it assumes a Microsoft Office Excel 2007 spreadsheet located at c:\temp called VendorList.xlsx. It looks for a tab in that spreadsheet called Vendors. The statement that does the writing just uses one column: Vendor Code. Here’s the breakdown of what I’m doing: In the first block, I connect to Microsoft Office Excel. That connection string is specific to Excel 2007, so if you need a different version you’ll need to look that up. In the second block I set up a selection from the entire spreadsheet based on that tab. Note that if you’re only after certain data you shouldn’t get the whole spreadsheet – that’s just good practice. In the next block I create the text I want, inserting the Vendor Code field as I go. Finally I close the connection. Enjoy! $ExcelConnection= New-Object -com "ADODB.Connection" $ExcelFile="c:\temp\VendorList.xlsx" $ExcelConnection.Open("Provider=Microsoft.ACE.OLEDB.12.0;` Data Source=$ExcelFile;Extended Properties=Excel 12.0;") $strQuery="Select * from [Vendors$]" $ExcelRecordSet=$ExcelConnection.Execute($strQuery) do { Write-Host "EXEC sp_InsertVendors '" $ExcelRecordSet.Fields.Item("Vendor Code").Value "'" $ExcelRecordSet.MoveNext()} Until ($ExcelRecordSet.EOF) $ExcelConnection.Close() Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems. Always check the script on a test system or Virtual Machine, not a production system. All scripts on this site are performed by a professional stunt driver on a closed course. Your mileage may vary. Void where prohibited. Offer good for a limited time only. Keep out of reach of small children. Do not operate heavy machinery while using this script. If you experience blurry vision, indigestion or diarrhea during the operation of this script, see a physician immediately.
