  • How do I prevent having to log in on 3 separate prompts every time I start my machine?

    - by JC
    Ubuntu 11.04 Natty Narwhal, Ubuntu Classic desktop Each time I start my machine, I have to log in 3 times. I spent a week in IRCFreenode#ubuntu and got nothing but condescension. I've searched on the official Ubuntu fora for similar problems, tried every recommendation, and still get 3 login screens. As a workaround, I have reset login such that I get a login screen at startup, which I'd prefer not to get since this machine is accessible by no one but me, physically. I have gone into System Preferences Passwords and Encryption Keys, set first 'Passwords: default' to 'Default' and unlocked it, and unlocked the 'Passwords: login' key, too. Next, since that changed nothing, I set 'Passwords: login' to 'Default', and checked to make sure it was still unlocked. Again, no change, still get 3 login prompts at startup. I've checked twice to insure that I am the owner of the files; I am. At the suggestion of several people in #ubuntu, I've deleted first one, then the other password key in 'Passwords and Encryption Keys'. Still get 3 login prompts. I changed from the Unity desktop to Ubuntu Classic. While that didn't fix the above problem, it is a much more elegant desktop than Unity, and I'll keep it. From what I've read, this seems to be a Seahorse issue, but beyond that, no one seems to have a solution that works. I'm lost. This shouldn't be this difficult or annoying. I'm trying to help our local Old Time music collective get their machines switched over to Ubuntu in order to save them some money which they can use to promote their DRM-free music. But from what I've seen of Ubuntu so far on my own machine, I can't really recommend that they make this switch. I hope to be proved wrong on that point. But as it stands, if I was out of town or out of country and they ran into a problem, they'd have no way of fixing it as they're all less experienced than even I am. I'm not trying to cast aspersions on Ubuntu or Linux, but it seems pretty clear that KNOWLEDGEABLE, HELPFUL support for Ubuntu is lacking barring any desire on the problem-experiencing-user's part to avoid condescension. Having worked with, and run, several non-profits over the past 20 years, I know that getting volunteers to act professionally can be like herding cats. But an organization's reputation can be denigrated by sarcastic behaviors on the part of those who serve, effectively, as its public face. Thank you all for your help and support. Now...does anyone have a solution to my problem?

  • HighPoint RocketRAID 62x Controller

    - by TeXnewbie
    I have the subject card recently installed in Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-31-generic x86_64). See partial lspci -vv listing below (complete listing played havoc with pre tags): 03:00.0 RAID bus controller: HighPoint Technologies, Inc. Device 0622 (rev 01) Subsystem: HighPoint Technologies, Inc. Device 0001 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Latency: 0, Cache Line Size: 32 bytes Interrupt: pin A routed to IRQ 11 Region 0: I/O ports at 9c00 [size=8] Region 1: I/O ports at 9800 [size=4] Region 2: I/O ports at 9400 [size=8] Region 3: I/O ports at 9000 [size=4] Region 4: I/O ports at 8c00 [size=16] Region 5: Memory at fdbff000 (32-bit, non-prefetchable) [size=2K] Expansion ROM at fdbe0000 [disabled] [size=64K] Capabilities: I followed instructions I found at https://help.ubuntu.com/community/RocketRaid to compile the drivers for it, and although performing the process described there seemed to work fine with no noticeable errors, when I rebooted after performing that procedure I could not boot. During dkms steps, I noticed messages indicating that (If next boot fails, revert to initrd.img-3.2.0-31-generic.old-dkms image) update-initramfs................ so I booted using a Ubuntu 12.10 LiveDVD and reverted to the old-dkms initrd.img as suggested above, but this failed to repair the boot problem. Ultimately, I used https://help.ubuntu.com/community/Boot-Repair in Ubuntu-Secure-Remix to fix the boot problem and was able to boot normally again, but now with the newly generated initrd.img in place again (which now boots normally), when I modprobe the rr62x kernel module, I immediately get a hard crash with messages to console about a kernel paging request that seems to have caused the problem. I've tried on multiple occasions now to use the newly built kernel module so as to allow me to use an eSATA port multiplier plugged into the card, but to no avail. Any suggestions on fixes or workarounds (I've read that some of the HighPoint cards (2720SGL) seem to work as a host bus adapter and thus may not need a custom driver, but that seems not to be the case for mine) would be most appreciated. My goal is to use the card as described here and with software RAID mdadm utilities. If necessary, I can hand-copy the console messages after the hard crash into a follow-up message, but I obviously can't do a cut/paste. I'll gladly provide any other details that are needed, but not sure what those would be at this point, so I'll refrain from adding other details for now. Thanks in advance for any help.

  • Book Review: Oracle ADF 11gR2 Development Beginner's Guide

    - by Grant Ronald
    Packt Publishing asked me to review Oracle ADF 11gR2 Development Beginner's Guide by Vinod Krishnan, so on a couple of long flights I managed to get through the book in a couple of sittings. One point to make clear before I go into the review.  Having authored "The Quick Start Guide to Fusion Development: JDeveloper and Oracle ADF", I've written a book which covers the same topic/beginner level.  I also think that its worth stating up front that I applaud anyone who has gone  through the effort of writing a technical book. So well done Vinod.  But on to the review: The book itself is a good break down of topic areas.  Vinod starts with a quick tour around the IDE, which is an important step given all the work you do will be through the IDE.  The book then goes through the general path that I tend to always teach: a quick overview demo, ADF BC, validation, binding, UI, task flows and then the various "add on" topics like security, MDS and advanced topics.  So it covers the right topics in, IMO, the right order.  I also think the writing style flows nicely as well - Its a relatively easy book to read, it doesn't get too formal and the "Have a go hero" hands on sections will be useful for many. That said, I did pick out a number of styles/themes to the writing that I found went against the idea of a beginners guide.  For example, in writing my book, I tried to carefully avoid talking about topics not yet covered or not yet relevant at that point in someone's learning.  So, if I was a new ADF developer reading this book, did I really need to know about ADFBindingFilter and DataBindings.cpx file on page 58 - I've only just learned how to do a drag and drop simple application so showing me XML configuration files relevant to JSF/ADF lifecycle is probably going to scare me off! I found this in a couple of places, for example, the security chapter starts on page 219 but by page 222 (and most of the preceding pages are hands-on steps) we're diving into the web.xml, weblogic.xml, adf-config.xml, jsp-config.xml and jazn-data.xml.  Don't get me wrong, I'm not saying you shouldn't know this, but I feel you have to get people on a strong grounding of the concepts before showing them implementation files.  If having just learned what ADF Security is will "The initialization parameter remove.anonymous.role is set to false for the JpsFilter filter as this filter is the first filter defined in the file" really going to help me? The other theme I found which I felt didn't work was that a couple of the chapters descended into a reference guide.  For example page 159 onwards basically lists UI components and their properties.  And page 87 onwards list the attributes of ADF BC in pretty much the same way as the on line help or developer guide, and I've a personal aversion to any sort of help that says pretty much what the attribute name is e.g. "Precision Rule: this option is used to set a strict precision rule", or "Property Set: this is the property set that has to be applied to the attribute". Hmmm, I think I could have worked that out myself, what I would want to know in a beginners guide are what are these for, what might I use them for...and if I don't need to use them to create an emp/dept example them maybe it’s better to leave them out. All that said, would the book help me - yes it would.  It’s obvious that Vinod knows ADF and his style is relatively easy going and the book covers all that it has to, but I think the book could have done a better job in the educational side of guiding beginners.

  • Wireless Broadcom 4313 not working on Ubuntu 12.04

    - by user88568
    It seems a lot of people are having this problem, but none of the posted solutions have worked for me so far. My driver is installed and activated, I have tried removing and re-adding the network, and various other fixes. No networks were picked up on my first boot, the next day wireless worked fine, and since then it does not detect networks, and when I manually try to connect, it repeatedly asks for the password and does not connect.

  • Automate RAC Cluster Upgrades using EM12c

    - by HariSrinivasan
    One of the most arduous processes  in DB maintenance is upgrading Databases across major versions, especially for complex RAC Clusters.With the release of Database Plug-in  (12.1.0.5.0), EM12c Rel 3 (12.1.0.3.0)  now supports automated upgrading of RAC Clusters in addition to Standalone Databases. This automation includes: Upgrade of the complete Cluster across the nodes. ( Example: 11.1.0.7 CRS, ASM, RAC DB  ->   11.2.0.4 or 12.1.0.1 GI, RAC DB)  Best practices in tune with your operations, where you can automate upgrade in steps: Step 1: Upgrade the Clusterware to Grid Infrastructure (Allowing you to wait, test and then move to DBs). Step 2: Upgrade RAC DBs either separately or in group (Mass upgrade of RAC DB's in the cluster). Standard pre-requisite checks like Cluster Verification Utility (CVU) and RAC checks Division of Upgrade process into Non-downtime activities (like laying down the new Oracle Homes (OH), running checks) to Downtime Activities (like Upgrading Clusterware to GI, Upgrading RAC) there by lowering the downtime required. Ability to configure Back up and Restore options as a part of this upgrade process. You can choose to : a. Take Backup via this process (either Guaranteed Restore Point (GRP) or RMAN) b. Set the procedure to pause just before the upgrade step to allow you to take a custom backup c. Ignore backup completely, if there are external mechanisms already in place.  High Level Steps: Select the Procedure "Upgrade Database" from Database Provisioning Home page. Choose the Target Type for upgrade and the Destination version Pick and choose the Cluster, it picks up the complete topology since the clusterware/GI isn't upgraded already Select the Gold Image of the destination version for deploying both the GI and RAC OHs Specify new OH patch, credentials, choose the Restore and Backup options, if required provide additional pre and post scripts Set the Break points in the procedure execution to isolate Downtime activities Submit and track the procedure's execution status.  The animation below captures the steps in the wizard.  For step by step process and to understand the support matrix check this documentation link. Explore the functionality!! In the next blog, will talk about automating rolling Upgrades of Databases in Physical Standby Data Guard environment using Transient Logical Standby.

  • JavaOne Latin America 2012 Trip Report

    - by reza_rahman
    JavaOne Latin America 2012 was held at the Transamerica Expo Center in Sao Paulo, Brazil on December 4-6. The conference was a resounding success with a great vibe, excellent technical content and numerous world class speakers. Some notable local and international speakers included Bruno Souza, Yara Senger, Mattias Karlsson, Vinicius Senger, Heather Vancura, Tori Wieldt, Arun Gupta, Jim Weaver, Stephen Chin, Simon Ritter and Henrik Stahl. Topics covered included the JCP/JUGs, Java SE 7, HTML 5/WebSocket, CDI, Java EE 6, Java EE 7, JSF 2.2, JMS 2, JAX-RS 2, Arquillian and JavaFX. Bruno Borges and I manned the GlassFish booth at the Java Pavilion on Tuesday and Webnesday. The booth traffic was decent and not too hectic. We met a number of GlassFish adopters including perhaps one of the largest GlassFish deployments in Brazil as well as some folks migrating to Java EE from Spring. We invited them to share their stories with us. We also talked with some key members of the local Java community. Tuesday evening we had the GlassFish party at the Tribeca Pub. The party was definitely a hit and we could have used a larger venue (this was the first time we had the GlassFish party in Brazil). Along with GlassFish enthusiasts, a number of Java community leaders were there. We met some of the same folks again at the JUG leader's party on Wednesday evening. On Thursday Arun Gupta, Bruno Borges and I ran a hands-on-lab on JAX-RS, WebSocket and Server-Sent Events (SSE) titled "Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket". This is the same Java EE 7 lab run at JavaOne San Francisco. The lab provides developers a first hand glipse of how an HTML 5 powered Java EE application might look like. We had an overflow crowd for the lab (at one point we had about twenty people standing) and the lab went very well. The slides for the lab are here: Developing JAX-RS Web Applications Utilizing Server-Sent Events and WebSocket from Reza Rahman The actual contents for the lab is available here. Give me a shout if you need help getting it up and running. I gave two solo talks following the lab. The first was on JMS 2 titled "What’s New in Java Message Service 2". This was essentially the same talk given by JMS 2 specification lead Nigel Deakin at JavaOne San Francisco. I talked about the JMS 2 simplified API, JMSContext injection, delivery delays, asynchronous send, JMS resource definition in Java EE 7, standardized configuration for JMS MDBs in EJB 3.2, mandatory JCA pluggability and the like. The session went very well, there was good Q & A and someone even told me this was the best session of the conference! The slides for the talk are here: What’s New in Java Message Service 2 from Reza Rahman My last talk for the conference was on JAX-RS 2 in the keynote hall. Titled "JAX-RS 2: New and Noteworthy in the RESTful Web Services API" this was basically the same talk given by the specification leads Santiago Pericas-Geertsen and Marek Potociar at JavaOne San Francisco. I talked about the JAX-RS 2 client API, asyncronous processing, filters/interceptors, hypermedia support, server-side content negotiation and the like. The talk went very well and I got a few very kind complements afterwards. The slides for the talk are here: JAX-RS 2: New and Noteworthy in the RESTful Web Services API from Reza Rahman On a more personal note, Sao Paulo has always had a special place in my heart as the incubating city for Sepultura and Soulfy -- two of my most favorite heavy metal musical groups of all time! Consequently, the city has a perpertually alive and kicking metal scene pretty much any given day of the week. This time I got to check out a solid performance by local metal gig Republica at the legendary Manifesto Bar. I also wanted to see a Dio Tribute at the Blackmore but ran out of time and energy... Overall I enjoyed the conference/Sao Paulo and look forward to going to Brazil again next year!

  • StreamInsight 1.0 Released

    - by Roman Schindlauer
    One piece in the set of products offered in SQL Server 2008 R2 that has generated a lot of buzz and interest during its CTP phase is StreamInsight, Microsoft’s platform for Complex Event Processing. Microsoft’s information platform vision provides enterprises with a “complete approach” to managing information assets, enabling all businesses to gain strategic value from information from the desktop to the datacenter to the cloud. And StreamInsight V1 is one essential piece in this spectrum. After more than a year of blood, sweat, tears, and insane amounts of coffee we are proud to release the first version of our Complex Event Processing Framework.   Those of you who have been following our Community Technology Previews (CTPs) throughout last year have already had the possibility to familiarize themselves with the product. Early feedback was not only incredibly positive, but also very constructive and strongly influenced the final feature set. Four notable increments over our last public CTP are: Count windows Non-occurrence detection (Anti-Join) Dynamic query composition at runtime Synchronize time across input streams Additionally, many smaller issues and bugs were addressed. A few APIs slightly changed with respect to the November CTP, but porting your application to RTM should not require a lot of effort.   Here are the (english) bits - choosing the evaluation license during setup lets you already play with this version. Before you install, make sure to uninstall any previous CTP version:   StreamInsight X86StreamInsight X64   Within a few days, we will update our product page and add download links and instructions there as well.   The StreamInsight documentation is provided through a help file as part of the installation as well as through Books Online on MSDN.

  • Communication between state machines with hidden transitions

    - by slartibartfast
    The question emerged for me in embedded programming but I think it can be applied to quite a number of general networking situations e.g. when a communication partner fails. Assume we have an application logic (a program) running on a computer and a gadget connected to that computer via e.g. a serial interface like RS232. The gadget has a red/green/blue LED and a button which disables the LED. The LEDs color can be driven by software commands over the serial interface and the state (red/green/blue/off) is read back and causes a reaction in the application logic. Asynchronous behaviour of the application logic with regard to the LED color down to a certain delay (depending on the execution cycle of the application) is tolerated. What we essentially have is a resource (the LED) which can not be reserved and handled atomically by software because the (organic) user can at any time press the button to interfere/break the software attempt to switch the LED color. Stripping this example from its physical outfit I dare to say that we have two communicating state machines A (application logic) and G (gadget) where G executes state changes unbeknownst to A (and also the other way round, but this is not significant in our example) and only A can be modified at a reasonable price. A needs to see the reaction and state of G in one piece of information which may be (slightly) outdated but not inconsistent with respect to the short time window when this information was generated on the side of G. What I am looking for is a concise method to handle such a situation in embedded software (i.e. no layer/framework like CORBA etc. available). A programming technique which is able to map the complete behaviour of both participants on classical interfaces of a classical programming language (C in this case). To complicate matters (or rather, to generalize), a simple high frequency communication cycle of A to G and back (IOW: A is rapidly polling G) is out of focus because of technical restrictions (delay of serial com, A not always active, etc.). What I currently see as a general solution is: the application logic A as one thread of execution an adapter object (proxy) PG (presenting G inside the computer), together with the serial driver as another thread a communication object between the two (A and PG) which is transactionally safe to exchange The two execution contexts (threads) on the computer may be multi-core or just interrupt driven or tasks in an RTOS. The com object contains the following data: suspected state (written by A): effectively a member of the power set of states in G (in our case: red, green, blue, off, red_or_green, red_or_blue, red_or_off...etc.) command data (written by A): test_if_off, switch_to_red, switch_to_green, switch_to_blue operation status (written by PG): operation_pending, success, wrong_state, link_broken new state (written by PG): red, green, blue, off The idea of the com object is that A writes whichever (set of) state it thinks G is in, together with a command. (Example: suspected state="red_or_green", command: "switch_to_blue") Notice that the commands issued by A will not work if the user has switched off the LED and A needs to know this. PG will pick up such a com object and try to send the command to G, receive its answer (or a timeout) and set the operation status and new state accordingly. A will take back the oject once it is no longer at operation_pending and can react to the outcome. The com object could be separated of course (into two objects, one for each direction) but I think it is convenient in nearly all instances to have the command close to the result. I would like to have major flaws pointed out or hear an entirely different view on such a situation.

  • Is This Your Idea of Disaster Recovery?

    - by rickramsey
    Don't just make do with less. Protect what you've got. By, for instance, deploying Oracle Solaris 10 inside a zone cluster. "Wait," you say, "what is a zone cluster?" It is a zone deployed across different physical servers. "Who would do that!" you ask in a mild panic. Why, an upstanding sysadmin citizen interested in protecting his or her employer's investment with appropriate high availability and disaster recovery. If one server gets wiped out by Hurricane Sandy along with pretty much the entire East Coast of the USA, your zone continues to run on the other server(s). Provided you set them up in Edinburgh. This white paper (pdf) explains what a zone cluster is and how to use it. If a white paper reminds you of having to read War and Peace in school, just use this Oracle RAC and Solaris Cluster Cheat Sheet, instead. "But wait!" you exclaim. "I didn't realize Solaris 10 offered zone clusters!" I didn't, either! And in an earlier version of this blog post I said that zone clusters were only available with Oracle Solaris 11. But Karoly Vegh pointed me to the documentation for Oracle Solaris Cluster 3.3, which explains how to manage zone clusters in Oracle Solaris 10. Bite my fist! So, the point I was trying to make is not just that you can run Oracle Solaris 10 zone clusters, but that you can run them in an Oracle Solaris 11 environment. Now let's return to our conversation and pick up where we left off ... "Oh no! Whatever shall I do?" Fear not. Remember how Oracle Solaris 11 lets you create a Solaris 10 branded zone inside a system running Oracle Solaris 11? Well, the Solaris Cluster engineers thought that was a bang-up idea, and decided to extend Oracle Solaris Cluster so that you could run your Solaris 10 applications inside the protective cocoon of an Oracle Solaris 11 zone cluster. Take advantage of the installation improvements and network virtualization capabilities of Oracle Solaris 11 while still running your application on Oracle Solaris 10. You Luddite, you. That capability is in the latest release of Oracle Solaris Cluster, version 4.1, which became available last Friday. "Last Friday! Is it too late to get a copy?" You can still get a free copy from our download center (see below). And, if you'd like to know what other goodies the 4.1 release of Oracle Solaris Cluster provides, see: What's New In Oracle Solaris Cluster 4.1 (pdf) Free download Oracle Solaris Cluster 4.1 (SPARC or x86) Tech Article: How to Upgrade to Oracle Solaris Cluster 4.0, by Tim Read. As always, you can get the latest information about Oracle Solaris Cluster, plus technical how-to articles, documentation, and more from Oracle Solaris Cluster Resource Page for Sysadmins and Developers. And don't forget about the online launch of Oracle Solaris 11.1 and Oracle Solaris Cluster 4.1, scheduled for Nov 7. "I feel so much better, now!" Think nothing of it. That's what we're here for. - Rick Website Newsletter Facebook Twitter

  • Be the surgeon

    - by Rob Farley
    It’s a phrase I use often, especially when teaching, and I wish I had realised the concept years earlier. (And of course, fits with this month’s T-SQL Tuesday topic, hosted by Argenis Fernandez) When I’m sick enough to go to the doctor, I see a GP. I used to typically see the same guy, but he’s moved on now. However, when he has been able to roughly identify the area of the problem, I get referred to a specialist, sometimes a surgeon. Being a surgeon requires a refined set of skills. It’s why they often don’t like to be called “Doctor”, and prefer the traditional “Mister” (the history is that the doctor used to make the diagnosis, and then hand the patient over to the person who didn’t have a doctorate, but rather was an expert cutter, typically from a background in butchering). But if you ask the surgeon about the pain you have in your leg sometimes, you’ll get told to ask your GP. It’s not that your surgeon isn’t interested – they just don’t know the answer. IT is the same now. That wasn’t something that I really understood when I got out of university. I knew there was a lot to know about IT – I’d just done an honours degree in it. But I also knew that I’d done well in just about all my subjects, and felt like I had a handle on everything. I got into developing, and still felt that having a good level of understanding about every aspect of IT was a good thing. This got me through for the first six or seven years of my career. But then I started to realise that I couldn’t compete. I’d moved into management, and was spending my days running projects, rather than writing code. The kids were getting older. I’d had a bad back injury (ask anyone with chronic pain how it affects  your ability to concentrate, retain information, etc). But most of all, IT was getting larger. I knew kids without lives who knew more than I did. And I felt like I could easily identify people who were better than me in whatever area I could think of. Except writing queries (this was before I discovered technical communities, and people like Paul White and Dave Ballantyne). And so I figured I’d specialise. I wish I’d done it years earlier. Now, I can tell you plenty of people who are better than me at any area you can pick. But there are also more people who might consider listing me in some of their lists too. If I’d stayed the GP, I’d be stuck in management, and finding that there were better managers than me too. If you’re reading this, SQL could well be your thing. But it might not be either. Your thing might not even be in IT. Find out, and then see if you can be a world-beater at it. But it gets even better, because you can find other people to complement the things that you’re not so good at. My company, LobsterPot Solutions, has six people in it at the moment. I’ve hand-picked those six people, along with the one who quit. The great thing about it is that I’ve been able to pick people who don’t necessarily specialise in the same way as me. I don’t write their T-SQL for them – generally they’re good enough at that themselves. But I’m on-hand if needed. Consider Roger Noble, for example. He’s doing stuff in HTML5 and jQuery that I could never dream of doing to create an amazing HTML5 version of PivotViewer. Or Ashley Sewell, a guy who does project management far better than I do. I could go on. My team is brilliant, and I love them to bits. We’re all surgeons, and when we work together, I like to think we’re pretty good! @rob_farley

  • how do I get dual monitors to work properly in Ubuntu 11.10 on a Dell Latitude D630?

    - by wes cook
    I have spent a lot of time trying to get dual monitors to work on Ubuntu 11.10 on my Dell Latitude D630 (nVidia NVS 135m video card). - For starters, the System Displays settings app always only showed one unknown monitor, even though I had the external Acer monitor connected. - So I downloaded and installed the nVidia drivers. According to what I read I would need to only use the nVidia driver app (nVidia X Server Settings), so that's what I've done. (System Displays settings continued to only show a single monitor anyway). - nVidia settings app only showed on monitor until I changed the BIOS setting to use the onboard video for external monitor (not the dock video, which it was set to, even though I don't have a docking station). - The nVidia setting app now recognized both monitors. So, I setup the X Server display config as Separate X screen for both monitors. My laptop screen shows up as AUO 1440x900 and my external monitor as Acer E211H 1920x1080. - Everything seemed like it would work, but the external monitor was just a complete white screen. The external monitor was non-functional, even though sometimes it would show the background image - still nothing would show up over there. - So, I checked the Enable Xinerama box. - Now, after logging out and back in, the wallpaper extends to both screens but I get no taskbar at the bottom or top, no system menus, and I have to press the power button to restart or log off. - After experimenting with all the shells, the only one that shows the menus and taskbars when I log in is Gnome Classic. - This is pretty much the same symptoms as found here: How do I fix 11.10 GUI?. - So, I resign myself to the older shell. - Everything works fine until ... I unplug the external monitor ... this is a laptop after all. - Anyway, after doing some work on the road, I plug back in and I still see both screens and it's functional except, ... - Now, the laptop screen (with the taskbar and menu bar) has 4 black bars at the top that windows cannot cover. The top bar is the menu bar (with Applications, Places, the date and time and the system menu on the right). But the next 3 bars (the same height as the top menu bar) are empty and are just reducing the max size of windows on that screen. - See screenshot here: http://i39.tinypic.com/35d2kh1.png - So ... 1. How do I get rid of those extra 3 black bars? They're taking valuable screen space. 2. (less critical) How do I successfully use both screens in the Ubuntu or Ubuntu 2D shell?

  • New Slides - and a discussion about Dictionary Statistics

    - by Mike Dietrich
    First of all we have just upoaded a new version of the Upgrade and Migration Workshop slides with some added information. So please feel free to download them from here.The slides have one new interesting information which lead to a discussion I've had in the past days with a very large customer regarding their upgrades - and internally on the mailing list targeting an EBS database upgrade from Oracle 10.2 to Oracle 11.2. Why are we creating dictionary statistics during upgrade? I'd believe this forced dictionary statistics creation got introduced with the desupport of the Rule Based Optimizer in Oracle 10g. The goal: as RBO is not supported anymore we have to make sure that the data dictionary has fresh and non-stale statistics. Actually that would have led in Oracle 9i to strange behaviour in some databases - so in Oracle 9i this was strongly disrecommended. The upgrade scripts got hardcoded to create these stats. But during tests we had the following findings: It's important to create dictionary statistics the night before the upgrade. Not two weeks before, not 60 minutes before your downtime begins. But very close to the upgrade. From Oracle 10g onwards you'd just say: $ execute DBMS_STATS.GATHER_DICTIONARY_STATS; This is important to make sure you have fresh dictionary statistics during upgrade for performance reasons. Tests have shown that running an upgrade without valid dictionary statistics might slow down the whole upgrade by factors of 2x-3x. And it would be also a great idea post upgrade to create again fresh dictionary statistics when you've did suppress the stats creation during the upgrade process. Suppress? Yes, you could set this underscore parameter in the init.ora: _optim_dict_stats_at_db_cr_upg=FALSE to suppress the forced dictionary statistics collection during an upgrade. We believe strongly that (a) people using the default statistics creation process which will create dictionary statistics by default and (b) create fresh stats before upgrade on the dictionary. Therefore we find it save once you have followed our advice to use the underscore during upgrade. And we've taken out that forced statistics collection during upgrade in the next release of the database. Please note: If you are using the DBUA for the upgrade it will remove underscore parameters for the upgrade run to improve performance - which is generally a good idea. So you'll have to start the DBUA with that call: $ dbua -initParam "_optim_dict_stats_at_cb_cr_upg"=FALSE -Mike

  • SharePoint Designer 2010 Workflow Email Link To Item

    - by Brian Jackett
    In this post I’ll walk you through the process of sending an email that contains a link to the current item from a SharePoint Designer 2010 workflow.  This is a process that has been published on many other forums and blogs, but many that I have seen are more complex than seems necessary. Problem     A common request from SharePoint users is to get an email which contains a link to review/approve/edit the workflow item.  SharePoint list items contain an automatic property for Url Path, but unfortunately that Url is not properly formatted to retrieve the item if you include it directly on the message body.  I tried a few solutions suggested from other blogs or forums that took a substring of the Url Path property, concatenated the display form view Url, and mixed in some other strings.  While I was able to get this working in some scenarios I still had issues in general. Solution     My solution involved adding a hyperlink to the message body.  This ended up being far easier than I had expected and fairly intuitive once I found the correct property to use.  Follow these steps to see what I did.     First add a “Send an Email” action to your workflow.  Edit the action to pull up the email configuration dialog.  Click the “Add hyperlink” button seen below. When prompted for the address of the link click the fx button to perform a lookup.  Choose Workflow Context from the “data source” dropdown.  Choose Current Item URL from the “field from source” dropdown.  Click OK. Your Edit Hyperlink dialog should now look something like this. The end result will be a hyperlink added to your email pointing to the current workflow item.  Note: this link points to the non-modal dialog display form (display form similar to what you had in 2007). Conclusion     In this post I walked you through the steps to create a SharePoint Designer 2010 workflow with an email that contains a link to the current item.  While there are many other options for accomplishing this out on the web I found this to be a more concise process and easy to understand.  Hopefully you found this helpful as well.  Feel free to leave any comments or feedback if you’ve found other ways that were helpful to you.         -Frog Out

  • Please Stop Voting Against a Candidate

    - by Brian Lanham
    DISCLAIMER:  This is not a post about “Romney” or “Obama”.  This is not a post for whom I am voting.  This is simply a post to address an issue that I cannot ignore any longer.  This two-party system that we have allowed to establish a foothold is killing this country.    More than 2 Options I was recently asked, “If you had to choose Romney or Obama who would you pick?”  I replied “Non sequiter.  The founders of this nation ensured that I never have to pick from only two candidates.”  But somehow that is the way this country’s citizens think.  I told someone last week that there are around 20 candidates for president and she was genuinely surprised.  (There are actually 25 candidates.)  She had no idea there were that many and, even though she knew there are more, she didn’t know any names beyond Romney and Obama.  Well, I am going to try and educate people like her on other options. Vote for a Candidate, not against another Candidate So this post is the first in a series with a little bit of information about each candidate for president.  I implore you…I beg you, please do your civic duty and conduct a little bit of investigation and research on your own to find the right candidate for you.  Hey, if your candidate is Romney or Obama, that’s fine.  As long as it’s an educated decision.  But please…stop voting against a candidate.  Start voting for a candidate. A List of CandidatesAs I mentioned, I am going to write a little something about each candidate and I’m going to go by alphabetical order by PARTY, then by CANDIDATE LAST NAME so as to not show any bias. P.S. – If you want to know the candidate I selected I am happy to tell you.  But that’s not what this series is about.PARTYCANDIDATEAmerica's Party   Tom HoeflingAmerican Third Position PartyMerlin MillerAmericans Elect PartyNo candidates met the requirement to enter into the online caucus.Constitution PartyVirgil GoodeDemocratic Party   Barack ObamaGrassroots Party   Jim CarlsonGreen Party   Jill SteinIndependent American Party   Will ChristensenJustice PartyRocky AndersonLibertarian Party   Gary JohnsonObjectivist PartyTom StevensPeace and Freedom Party   Roseanne BarrReform PartyAndre BarnettRepublican PartyMitt RomneySocialism and Liberation PartyPeta LindsaySocialist Equality PartyJerry WhiteSocialist Party USAStewart AlexanderSocialist Workers PartyJames HarrisIndependent Candidates Jeff BossRichard DuncanJerry Litzel Dean Morstad Jill Reed Randall TerrySheila Tittle Michael Vargo

  • Removing Barriers to Create Effective Data Models

    After years of creating and maintaining data models, I have started to notice common barriers that decrease the accuracy and usefulness of models. In my opinion, the main causes of these barriers are the lack of knowledge and communication from within a company. The lack of knowledge in regards to data models or data modeling can take many forms. Company Culture Knowledge Whether documented or undocumented, existing business rules of a company can affect how data is modeled. For example, if a company only allows 1 assigned person per customer to be able to manipulate a customer’s record then then a data model that includes an associated table that joins customers and employee’s would be unneeded because that would allow for the possibility of multiple employees to handle a customer because of the potential for a many to many relationship between Customers and Employees. Technical Knowledge Depending on the data modeler’s proficiency in modeling data they can inadvertently cause issues and/or complications with a design without even noticing. It is important that companies share data modeling responsibilities so that the models are developed from multiple perspectives of a system, company and the original problem.  In addition, the tools that a company selects to create data models can also affect the accuracy of the model if designer are not familiar with the tools or the tools are too complex to use for the designer. Existing System Knowledge In order for a data modeler to model data for an existing system so that new changes can be applied to a system then they need to at least know the basic concepts of a system so that they can work within it. This will promote reusability of data and prevent the chance of duplicating data. Project Knowledge This should be pretty obvious, but it is very hard to create an accurate data model without knowing what data needs to be modeled. I have always found it strange that I have been asked to start modeling data prior to a client formalizing any requirements. Usually when this happens I have to make several iterations to a model, and the client still does not know exactly what they want.  In addition additional issues can arise when certain stakeholders of a project are not consulted prior to the design or after the project is over because it can cause miss understandings and confusion by the end user as well as possibly not solving the original problem for which a project is intended to solve. One common thread between each type of knowledge is that they can all be avoided through the use of good communication. For example, if a modeler is new to a company then they should ask older employees about any business specific rules that may be documented or undocumented that must be applied to projects in general. Furthermore, if a modeler is not really familiar with a specific data modeling software then they need to speak up and ask for help form other employees or their manager. This will not only help the modeler in the project, but also help them in future projects that they do for the company. Additionally, if a project is not clearly defined prior to a data modeler being assigned the modeling project then it is their responsibility to communicate with the other stakeholders to clarify any part of a project that is unclear so that the data model that is created is accurately aligned with a project.

  • Start Time & Calculated Column Wonkiness in a SharePoint Event Calendar

    - by _zekeMouseOver
    I was creating some custom rollups on some of our event calendars and came across a very odd bug when trying to grab only the date component of the built-in Start Time field. One's first inclination will be to create a calculated column and give it the formula... =[Start Time]... and then assign its output type to be "Date Only." This works well until a user adds an All Day Event. For reasons unexplainable, the All Day Event flag causes your =[Start Time] to display the date minus one day. Here is an example of this in action:  Start Date and Time, Duration, Start Date Value and Start Day are all calculated fields. Notice how the Start Date and Time (=[Start Time]) is reporting 6:00PM of the previous day. The Start Date Value (=[Start Time] - Output Type: Number) confirms this (.75 = 6:00 PM.) Curiously enough, the Duration (=[End Time]-[Start Time]) is properly reporting the duration between 12:00AM and 11:59PM. Why? I don't know. Perhaps it's somehow bound to the regional settings on the site, but I'm not interested in changing a global site setting for the sake of one calculated field.With this information at our disposal, our calculated column to display the date part of the start date needs to be modified to add one day to the [Start Time] field if an All Day Event is selected. To determine this, we use the Duration above to assume the item is an all-day event and change our formula to be:=IF(TEXT(([End Time]-[Start Time])-TRUNC(([End Time]-[Start Time]),0),"0.000000000")="0.999305556",[Start Time] + 1, [Start Time])This will work, but what happens when the user de-selects the "All Day Event" checkbox? The duration stays the same, but all other values begin reporting the correct time: Since our formula above is strictly based on an expected duration, it will add one to the correct date, causing the date 5/11/2010 to appear. Notice though that the raw value of the start time (in this case) is a non-fractional number (40,308) whereas the all-day event was being represented as 6:00 PM (.75) of the previous day. We can use this to add one more nested branch of logic to our calculation:=IF(TEXT(([End Time]-[Start Time])-TRUNC(([End Time]-[Start Time]),0),"0.000000000")="0.999305556",IF([Start Time]=ROUND([Start Time],0),[Start Time],[Start Time]+1),[Start Time]) I feel somewhat... dirty about having to resort to this kind of calculation in what SHOULD have been a simple =[Start Time] to extract the date part of the Start Time field, but there you have it. Make sure to shower extra longer after having used it.
