  • Booting Linux from External HDD, with persistence

    - by Moriarty
    I am trying to install Linux, specifically Lubuntu or BackTrack 5 on an external HDD (Seagate FreeAgent GoFlex) but I have had no luck using YUMI, or Untebootin to get it working. I want the hard drive to be able to save the data within Linux (As in, If I install a program, it will stay there). I also tried doing this with a flash drive, which does boot, but it does not save data (I tried following Pendrive's tutorial on creating a casper-rw file and adding "persistent" to various files, but I cannot get it to save files. Basically, I just want a form of linux on a portable device that will save files and settings between boots Note: I do not have a CD to install from. Any help would be greatly appreciated, Thanks!

  • Is it possible for a router to "go bad" with time?

    - by JQAn
    I've been having problems with my internet connection over the past weeks (intermittent disconnections, slow transfers, etc), and my provider keeps telling me that the problem is not on their end. I have cablemodem with a wifi router (this router was not provided by them). The router is quite old (DIR-300), so I'm starting to wonder if it could be the issue and if I should replace it. Is it possible that it is the cause? Can they become so outdated that they cause intermittent interruptions of service? If I reset the modem and the router, they work fine for a few hours, but the problems starts again after a while.

  • USB 3.0 ports backwards compatibility problems with 2.0 devices?

    - by AaronLS
    I see some info on the net that suggest that I should be able to get my USB 2.0 devices to work in 3.0 ports. I only have two 2.0 ports on my new computer, and six 3.0 ports. I have installed drives. There's two different drivers, I guess some of the ports are supported by the intel board and some supported by some other chipset on the motherboard. I however have yet to get any of the 3.0 ports to work, and my brother had had the same issue with his devices not working in 3.0 ports on his computer. So I am beginning to wonder if the backwards compatibility isn't reliable for some reason. Maybe manufacturers opting not to implement 2.0 support on the 3.0 ports. I understand that physically the wiring is there, but that is only half the story. Beyond my brother's and my own computers (different motherboards/everything), I have yet to see a 2.0 device work in a 3.0 port. Is there any reason for this apparent device incompatibility? I.e. looking for responses that would indicate what areas to explore for issues or if there is any known cases of manufacturers deviating from spec in hardware or drivers. I am aware it's "supposed" to work :) Update: Does this have any relation to "USB Legacy Support" options in the BIOS? There several options combinations of options with "USB Legacy Support" and "USB 3.0 Legacy Support" and the description for these is a bit confusing, sounds like a bad translation.

  • How to upgrade iPhone 3G to iOS 5 now that iOS 6 is out? [closed]

    - by mmmshuddup
    My friend has an old iPhone 3G and I wanted to upgrade it to iOS 5 because I had read that the performance is actually better with iOS 5 on that phone in spite of the difference in processor power. The problem is that now that iOS 6 is out, iTunes only gives me the option to upgrade to that. I am a little more leery of iOS 6 knowing that it was launched mostly for the iPhone 5 and since that phone has a way faster processor, I would assume that performance would be an issue on the iPhone 3G. How can I, if possible, upgrade just to iOS 5? Note: I would like to avoid having to jailbreak the phone by all means possible. (It's not mine and I don't want to take the risk with a phone that doesn't belong to me.) EDIT: If anyone knows of a good site to get help on questions like this let me know. Apparently you're allowed to ask questions about iPhones here, just not this. Which is completely utter asinine, but oh well. Anyone with helpful ideas, post in the comments please.

  • Sharing storage on Linux and Solaris

    - by devlearn
    I'm looking for a solution in order to share a san mounted volume between several hosts running on Linux (RHEL) and/or Solaris (Sparc). Note that I basically need to share a set of directories containing large binary files that are accessed in random R/W mode. I have the following reqs : keep the data on the SAN suitable i/o performances as the software is pretty demanding on IOPS stick to a shared file system as I can't afford a cluster fs (lack of MDS/OSS infrastructure) compression could be really usefull For now I've found only the following candidates : GFS2 , supports Linux only, no compression VxFS , supports Linux and Solaris, compression supported So if you have some suggestions for this list, I'll really welcome them. Thanks in advance,

  • ATI Radeon Drivers works with which linux distribution and version?

    - by amit.codename13
    I have ATI Mobility Radeon HD 5850 graphics card. Almost every new linux distribution seems to have an issue with it, when i install the drivers. Working without utilizing the graphics card leaves me so unproductive. So i made a plan to use older versions of linux, any distribution suitable as a desktop distribution. UPDATE: The kind of problems that i am facing are, 1) After installing drivers the system boots and hangs, 2) There are unusual lines over the screen 3) After upgrade system doesn't start properly(hangs the usual old way) The kind of answers i am looking for is, distribution X(the newer the version the better) doesn't have the above problem after installing drivers for ATI Mobility Radeon HD 5850 graphics card. UPDATE: The new drivers released by AMD seems to fix all the issues, although they are still beta Thanks

  • iTunes high CPU usage

    - by Calm Storm
    I upgraded to iTunes 10.4.1 and use Windows 7 and my itunes library is not that large at all (say about 20gb) When I start iTunes the CPU goes between 60-80% and stays there for a long time. I see that the itunes.exe takes about 70% of CPU in Process Explorer and it spawns a SearchProtocolHost.exe every 2 mins or so which takes < 0.1% CPU. Other than that iTunes.exe is always at 70-90% and never lets me do anything else. Does someone have a suggestion? EDIT: I have tried reinstalling 10.4.1 completely deleting my library and starting with a plain installation and that does not work I have tried downgrading to 10.3.x and that does not work either :(

  • DVI splitter not working as expected/confusion between DVI-D and -I

    - by Freakishly
    Hey guys, thanks for looking. I have an ATI FirePro™ V3700 in my desktop machine, and I have been running a dual-monitor setup quite effortlessly, thanks to the two DVI ports on the card. I came upon a third monitor, and wanted to extend my desktop to 3 screens, so I purchased a DVI splitter from Amazon. Now, I can only duplicate the second monitor onto the third, not extend it. I've tried all possible combinations of input to no avail. Here's the setup: The ATI FirePro™ V3700 has two Dual-Link DVI-I outputs The splitter splits a single Dual-Link DVI-I port into two Dual-Link DVI-I outputs Two of the monitors are NEC E222W, and the third monitor is a Dell 2001FP. Each monitor has one D-Sub and one Dual-Link DVI-D input. Cables going from the video card to the monitors are two Dual-Link DVI-D to the NECs and one Single-Link DVI-D to the Dell. Is the problem likely with the DVI-D/DVI-I mismatch? Or is it with the cable on the Dell that is only a Single-Link? The cables are easily replaceable, the monitors not so much. Thanks for your time, I really appreciate it. http://www.amd.com/us/products/workstation/graphics/ati-firepro-3d/v3700/Pages/v3700-specs.aspx http://www.amazon.com/Cables-Unlimited-DVI-D-Splitter-PCM-2260/product-reviews/B000H09RFM/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1 www dot newegg dot com/Product/Product.aspx?Item=N82E16824002495 accessories dot us dot dell dot com/sna/PopupProductDetail.aspx?cs=19&l=en&c=us&sku=320-1578 Apologies for the fudged links, I'm new here and they won't let me post more than two :P

  • Change the white background in webpages to another color

    - by Bruce Connor
    I'm currently using a dark theme in firefox. It looks really nice, but many webpages use a plain white background. The resulting contrast is a little unpleasant and sometimes hurts the eye when I switch from a dark tab to a white tab. Is there a way to make firefox replace white backgrouns everywhere with some other color (light gray, for instance)? It could be a Stylish script, a userChrome.css hack, or anything that works (preferably as light as possible). To make myself clear: after I achieve my objective, the background color whenever I visit the super-user site should be light-grey instead of white, and the same should happen to any other site with a white background (google sites, tech crunch, etc). Is there a way to do that?

  • SQL SERVER – Solution – 2 T-SQL Puzzles – Display Star and Shortest Code to Display 1

    - by pinaldave
    Earlier on this blog we had asked two puzzles. The response from all of you is nothing but Amazing. I have received 350+ responses. Many are valid and many were indeed something I had not thought about it. I strongly suggest you read all the puzzles and their answers here - trust me if you start reading the comments you will not stop till you read every single comment. Seriously trust me on it. Personally I have learned a lot from it. Let us recap the puzzles here quickly. Puzzle 1: Why following code when executed in SSMS displays result as a * (Star)? SELECT CAST(634 AS VARCHAR(2)) Puzzle 2: Write the shortest code that produces results as 1 without using any numbers in the select statement. Bonus Q: How many different Operating System (OS) NuoDB support? As I mentioned earlier the participation was nothing but Amazing. I will write about the winners and the best answers in short time. Meanwhile I will give to the point answers to above puzzles. Solution 1: When you convert character or binary expressions (char, nchar, nvarchar, varchar,binary, or varbinary) to an expression of a different data type, data can be truncated, only partially displayed, or an error is returned because the result is too short to display. Conversions to char, varchar, nchar, nvarchar, binary, and varbinary are truncated, except for the conversions shown in the following table. Reference of the text and table from MSDN. Solution 2: The shortest code to produce answer 1 : SELECT EXP($) or SELECT COS($) or SELECT DAY($) When SELECT $ it gives us the result as 0.00 and the EXP of the same is 1. I believe it is pretty neat. There were plenty other answers but this was the shortest. Another shorter answer would be PRINT EXP($) but no one has proposed that as in original Question I have explicitly mentioned SELECT in the original question. Bonus Answer: 5 OS: Windows, MacOS, Linux, Solaris, Joyent SmartOS Reference Please do read every single comment here. Do leave a comment which one do you think is the best comment out of all the comments. Meanwhile if there is a better solution and I have missed it do let me know as we still have time to correct it. I will be selecting the winner before the weekend as I am going through each and every of 350 comment. I will be selecting the best comments along with the winning comment. If our selection matches – one of you may still win something cool.  Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: PostADay, SQL, SQL Authority, SQL Puzzle, SQL Query, SQL Server, SQL Tips and Tricks, SQLServer, T SQL, Technology Tagged: NuoDB

  • JavaOne 2012 Sunday Strategy Keynote

    - by Janice J. Heiss
    At the Sunday Strategy Keynote, held at the Masonic Auditorium, Hasan Rizvi, EVP, Middleware and Java Development, stated that the theme for this year's JavaOne is: “Make the future Java”-- meaning that Java continues in its role as the most popular, complete, productive, secure, and innovative development platform. But it also means, he qualified, the process by which we make the future Java -- an open, transparent, collaborative, and community-driven evolution. "Many of you have bet your businesses and your careers on Java, and we have bet our business on Java," he said.Rizvi detailed the three factors they consider critical to the success of Java--technology innovation, community participation, and Oracle's leadership/stewardship. He offered a scorecard in these three realms over the past year--with OS X and Linux ARM support on Java SE, open sourcing of JavaFX by the end of the year, the release of Java Embedded Suite 7.0 middleware platform, and multiple releases on the Java EE side. The JCP process continues, with new JSR activity, and JUGs show a 25% increase in participation since last year. Oracle, meanwhile, continues its commitment to both technology and community development/outreach--with four regional JavaOne conferences last year in various part of the world, as well as the release of Java Magazine, with over 120,000 current subscribers. Georges Saab, VP Development, Java SE, next reviewed features of Java SE 7--the first major revision to the platform under Oracle's stewardship, which has included near-monthly update releases offering hundreds of fixes, performance enhancements, and new features. Saab indicated that developers, ISVs, and hosting providers have all been rapid adopters of the platform. He also noted that Oracle's entire Fusion middleware stack is supported on SE 7. The supported platforms for SE 7 has also increased--from Windows, Linux, and Solaris, to OS X, Linux ARM, and the emerging ARM micro-server market. "In the last year, we've added as many new platforms for Java, as were added in the previous decade," said Saab.Saab also explored the upcoming JDK 8 release--including Project Lambda, Project Nashorn (a modern implementation of JavaScript running on the JVM), and others. He noted that Nashorn functionality had already been used internally in NetBeans 7.3, and announced that they were planning to contribute the implementation to OpenJDK. Nandini Ramani, VP Development, Java Client, ME and Card, discussed the latest news pertaining to JavaFX 2.0--releases on Windows, OS X, and Linux, release of the FX Scene Builder tool, the JavaFX WebView component in NetBeans 7.3, and an OpenJFX project in OpenJDK. Nandini announced, as of Sunday, the availability for download of JavaFX on Linux ARM (developer preview), as well as Scene Builder on Linux. She noted that for next year's JDK 8 release, JavaFX will offer 3D, as well as third-party component integration. Avinder Brar, Senior Software Engineer, Navis, and Dierk König, Canoo Fellow, next took the stage and demonstrated all that JavaFX offers, with a feature-rich, animation-rich, real-time cargo management application that employs Canoo's just open-sourced Dolphin technology.Saab also explored Java SE 9 and beyond--Jigsaw modularity, Penrose Project for interoperability with OSGi, improved multi-tenancy for Java in the cloud, and Project Sumatra. Phil Rogers, HSA Foundation President and AMD Corporate Fellow, explored heterogeneous computing platforms that combine the CPU and the parallel processor of the GPU into a single piece of silicon and shared memory—a hardware technology driven by such advanced functionalities as HD video, face recognition, and cloud workloads. Project Sumatra is an OpenJDK project targeted at bringing Java to such heterogeneous platforms--with hardware and software experts working together to modify the JVM for these advanced applications and platforms.Ramani next discussed the latest with Java in the embedded space--"the Internet of things" and M2M--declaring this to be "the next IT revolution," with Java as the ideal technology for the ecosystem. Last week, Oracle released Java ME Embedded 3.2 (for micro-contollers and low-power devices), and Java Embedded Suite 7.0 (a middleware stack based on Java SE 7). Axel Hansmann, VP Strategy and Marketing, Cinterion, explored his company's use of Java in M2M, and their new release of EHS5, the world's smallest 3G-capable M2M module, running Java ME Embedded. Hansmaan explained that Java offers them the ability to create a "simple to use, scalable, coherent, end-to-end layer" for such diverse edge devices.Marc Brule, Chief Financial Office, Royal Canadian Mint, also explored the fascinating use-case of JavaCard in his country's MintChip e-cash technology--deployable on smartphones, USB device, computer, tablet, or cloud. In parting, Ramani encouraged developers to download the latest releases of Java Embedded, and try them out.Cameron Purdy, VP, Fusion Middleware Development and Java EE, summarized the latest developments and announcements in the Enterprise space--greater developer productivity in Java EE6 (with more on the way in EE 7), portability between platforms, vendors, and even cloud-to-cloud portability. The earliest version of the Java EE 7 SDK is now available for download--in GlassFish 4--with WebSocket support, better JSON support, and more. The final release is scheduled for April of 2013. Nicole Otto, Senior Director, Consumer Digital Technology, Nike, explored her company's Java technology driven enterprise ecosystem for all things sports, including the NikeFuel accelerometer wrist band. Looking beyond Java EE 7, Purdy mentioned NoSQL database functionality for EE 8, the concurrency utilities (possibly in EE 7), some of the Avatar projects in EE 7, some in EE 8, multi-tenancy for the cloud, supporting SaaS applications, and more.Rizvi ended by introducing Dr. Robert Ballard, oceanographer and National Geographic Explorer in Residence--part of Oracle's philanthropic relationship with the National Geographic Society to fund K-12 education around ocean science and conservation. Ballard is best known for having discovered the wreckage of the Titanic. He offered a fascinating video and overview of the cutting edge technology used in such deep-sea explorations, noting that in his early days, high-bandwidth exploration meant that you’d go down in a submarine and "stick your face up against the window." Now, it's a remotely operated, technology telepresence--"I think of my Hercules vehicle as my equivalent of a Na'vi. When I go beneath the sea, I actually send my spirit." Using high bandwidth satellite links, such amazing explorations can now occur via smartphone, laptop, or whatever platform. Ballard’s team regularly offers live feeds and programming out to schools and the world, spanning 188 countries--with embedding educators as part of the expeditions. It's technology at its finest, inspiring the next-generation of scientists and explorers!

  • Java EE at JavaOne - A Few Picks from a Very Rich Line-up

    - by Janice J. Heiss
    A rich and diverse set of sessions cast a spotlight on Java EE at this year’s JavaOne, ranging from the popular Web Framework Smackdown, to Java EE 6 and Spring, to sessions exploring Java EE 7, and one on the implications of HTML5. Some of the world’s best EE architects and developers will be sharing their insight and expertise. If only I could be at ten places at once!BOF4149 - Web Framework Smackdown 2012    Markus Eisele - Principal IT Architect, msg systems ag    Graeme Rocher - Senior Staff Engineer, VMware    James Ward - Developer Evangelist, Heroku    Ed Burns - Consulting Member of Technical Staff, Oracle    Santiago Pericasgeertsen - Software Engineer, Oracle* Monday, Oct 1, 8:30 PM - 9:15 PM - Parc 55 - Cyril Magnin II/III Much has changed since the first Web framework smackdown, at JavaOne 2005. Or has it? The 2012 edition of this popular panel discussion surveys the current landscape of Web UI frameworks for the Java platform. The 2005 edition featured JSF, Webwork, Struts, Tapestry, and Wicket. The 2012 edition features representatives of the current crop of frameworks, with a special emphasis on frameworks that leverage HTML5 and thin-server architecture. Java Champion Markus Eisele leads the lively discussion with panelists James Ward (Play), Graeme Rocher (Grails), Edward Burns (JSF) and Santiago Pericasgeertsen (Avatar).CON6430 - Java EE and Spring Framework Panel Discussion    Richard Hightower - Developer, InfoQ    Bert Ertman - Fellow, Luminis    Gordon Dickens - Technical Architect, IT101, Inc.    Chris Beams - Senior Technical Staff, VMware    Arun Gupta - Technology Evangelist, Oracle* Tuesday, Oct 2, 10:00 AM - 11:00 AM - Parc 55 - Cyril Magnin II/III In the age of Java EE 6 and Spring 3, enterprise Java developers have many architectural choices, including Java EE 6 and Spring, but which one is right for your project? Many of us have heard the debate and seen the flame wars—it’s a topic with passionate community members, and it’s a vibrant debate. If you are looking for some level-headed discussion, grounded in real experience, by developers who have tried both, then come join this discussion. InfoQ’s Java editors moderate the discussion, and they are joined by independent consultants and representatives from both Java EE and VMWare/SpringSource.BOF4213 - Meet the Java EE 7 Specification Leads   Linda Demichiel - Consulting Member of Technical Staff, Oracle   Bill Shannon - Architect, Oracle* Tuesday, Oct 2, 5:30 PM - 6:15 PM – Parc 55 - Cyril Magnin II/III This is your chance to meet face-to-face with the engineers who are developing the next version of the Java EE platform. In this session, the specification leads for the leading technologies that are part of the Java EE 7 platform discuss new and upcoming features and answer your questions. Come prepared with your questions, your feedback, and your suggestions for new features in Java EE 7 and beyond.CON10656 - JavaEE.Next(): Java EE 7, 8, and Beyond    Ian Robinson - IBM Distinguished Engineer, IBM    Mark Little - JBoss CTO, NA    Scott Ferguson - Developer, Caucho Technology    Cameron Purdy - VP Development, Oracle*Wednesday, Oct 3, 4:30 PM - 5:30 PM - Parc 55 - Cyril Magnin II/IIIIn this session, hear from a distinguished panel of industry and open source luminaries regarding where they believe the Java EE community is headed, starting with Java EE 7. The focus of Java EE 7 and 8 is mostly on the cloud, specifically aiming to bring platform as a service (PaaS) providers and application developers together so that portable applications can be deployed on any cloud infrastructure and reap all its benefits in terms of scalability, elasticity, multitenancy, and so on. Most importantly, Java EE will leverage the modularization work in the underlying Java SE platform. Java EE will, of course, also update itself for trends such as HTML5, caching, NoSQL, ployglot programming, map/reduce, JSON, REST, and improvements to existing core APIs.CON7001 - HTML5 WebSocket and Java    Danny Coward - Java, Oracle*Wednesday, Oct 3, 4:30 PM - 5:30 PM - Parc 55 - Cyril Magnin IThe family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform.

  • JavaOne User Group Sunday

    - by Tori Wieldt
    Before any "official" sessions of JavaOne 2012, the Java community was already sizzling. User Group Sunday was a great success, with several sessions offered by Java community members for anyone wanting to attend. Sessions were both about Java and best practices for running a JUG. Technical sessions included "Autoscaling Web Java Applications: Handle Peak Traffic with Zero Downtime and Minimized Cost,"  "Using Java with HTML5 and CSS3," and "Gooey and Sticky Bits: Everything You Ever Wanted to Know About Java." Several sessions were about how to start and run a JUG, like "Getting Speakers, Finding Sponsors, Planning Events: A Day in the Life of a JUG" and "JCP and OpenJDK: Using the JUGs’ “Adopt” Programs in Your Group." Badr ElHouari and Faiçal Boutaounte presented the session "Why Communities Are Important and How to Start One." They used the example of the Morocco JUG, which they started. Before the JUG, there was no "Java community," they explained. They shared their best practices, including: have fun, enjoy what you are doing get a free venue to have regular meetings, a University is a good choice run a conference, it gives you visibility and brings in new members students are a great way to grow a JUG Badr was proud to mention JMaghreb, a first-time conference that the Morocco JUG is hosting in November. They have secured sponsors and international speakers, and are able to offer a free conference for Java developers in North Africa. The session also included a free-flowing discussion about recruiters (OK to come to meetings, but not to dominate them), giving out email addresses (NEVER do without permission), no-show rates (50% for free events) and the importance of good content (good speakers really help!). Trisha Gee, member of the London Java Community (LJC) was one of the presenters for the session "Benefits of Open Source." She explained how open sourcing the LMAX Disruptor (a high performance inter-thread messaging library) gave her company LMAX several benefits, including more users, more really good quality new hires, and more access to 3rd party companies. Being open source raised the visibility of the company and the product, which was good in many ways. "We hired six really good coders in three months," Gee said. They also got community contributors for their code and more cred with technologists. "We had been unsuccessful at getting access to executives from other companies in the high-performance space. But once we were open source, the techies at the company had heard of us, knew our code was good, and that opened lots of doors for us." So, instead of "giving away the secret sauce," by going open source, LMAX gained many benefits. "It was a great day," said Bruno Souza, AKA The Brazilian Java Man, "the sessions were well attended and there was lots of good interaction." Sizzle and steak!

  • Wireframing: A Day In the Life of UX Workshop at Oracle

    - by ultan o'broin
    The Oracle Applications User Experience team's Day in the Life (DITL) of User Experience (UX) event was run in Oracle's Redwood Shores HQ for Oracle Usability Advisory Board (OUAB) members. I was charged with putting together a wireframing session, together with Director of Financial Applications User Experience, Scott Robinson (@scottrobinson). Example of stunning new wireframing visuals we used on the DITL events. We put on a lively show, explaining the basics of wireframing, the concepts, what it is and isn't, considerations on wireframing tool choice, and then imparting some tips and best practices. But the real energy came when the OUAB customers and partners in the room were challenge to do some wireframing of their own. Wireframing is about bringing your business and product use cases to life in real UX visual terms, by creating a low-fidelity drawing to iterate and agree on in advance of prototyping and coding what is to be finally built and rolled out for users. All the best people wireframe. Leonardo da Vinci used "cartoons" on some great works, tracing outlines first and using red ochre or charcoal dropped through holes in the tracing parchment onto the canvas to outline the subject. (Image distributed under Wikimedia commons license) Wireframing an application's user experience design enables you to: Obtain stakeholder buy-in. Enable faster iteration of different designs. Determine the task flow navigation paths (in Oracle Fusion Applications navigation is linked with user roles). Develop a content strategy (readability, search engine optimization (SEO) of content, and so on) Lay out the pages, widgets, groups of features, and so on. Apply usability heuristics early (no replacement for usability testing, but a great way to do some heavy-lifting up front). Decide upstream which functional user experience design patterns to apply (out of the box solutions that expedite productivity). Assess which Oracle Application Development Framework (ADF) or equivalent technology components can be used (again, developer productivity is enhanced downstream). We ran a lively hands-on exercise where teams wireframed a choice of application scenarios using the time-honored tools of pen and paper. Scott worked the floor like a pro, pointing out great use of features, best practices, innovations, and making sure that the whole concept of wireframing, the gestalt, transferred. "We need more buttons!" The cry of the energized. Not quite. The winning wireframe session (online shopping scenario) from the Applications UX DITL event shown. Great fun, great energy, and great teamwork were evident in the room. Naturally, there were prizes for the best wireframe. Well, actually, prizes were handed out to the other attendees too! An exciting, slightly different aspect to delivery of this session made the wireframing event one of the highlights of the day. And definitely, something we will repeat again when we get the chance. Thanks to everyone who attended, contributed, and helped organize.

  • Best Practices - which domain types should be used to run applications

    - by jsavit
    This post is one of a series of "best practices" notes for Oracle VM Server for SPARC (formerly named Logical Domains) One question that frequently comes up is "which types of domain should I use to run applications?" There used to be a simple answer in most cases: "only run applications in guest domains", but enhancements to T-series servers, Oracle VM Server for SPARC and the advent of SPARC SuperCluster have made this question more interesting and worth qualifying differently. This article reviews the relevant concepts and provides suggestions on where to deploy applications in a logical domains environment. Review: division of labor and types of domain Oracle VM Server for SPARC offloads many functions from the hypervisor to domains (also called virtual machines). This is a modern alternative to using a "thick" hypervisor that provides all virtualization functions, as in traditional VM designs, This permits a simpler hypervisor design, which enhances reliability, and security. It also reduces single points of failure by assigning responsibilities to multiple system components, which further improves reliability and security. In this architecture, management and I/O functionality are provided within domains. Oracle VM Server for SPARC does this by defining the following types of domain, each with their own roles: Control domain - management control point for the server, used to configure domains and manage resources. It is the first domain to boot on a power-up, is an I/O domain, and is usually a service domain as well. I/O domain - has been assigned physical I/O devices: a PCIe root complex, a PCI device, or a SR-IOV (single-root I/O Virtualization) function. It has native performance and functionality for the devices it owns, unmediated by any virtualization layer. Service domain - provides virtual network and disk devices to guest domains. Guest domain - a domain whose devices are all virtual rather than physical: virtual network and disk devices provided by one or more service domains. In common practice, this is where applications are run. Typical deployment A service domain is generally also an I/O domain: otherwise it wouldn't have access to physical device "backends" to offer to its clients. Similarly, an I/O domain is also typically a service domain in order to leverage the available PCI busses. Control domains must be I/O domains, because they boot up first on the server and require physical I/O. It's typical for the control domain to also be a service domain too so it doesn't "waste" the I/O resources it uses. A simple configuration consists of a control domain, which is also the one I/O and service domain, and some number of guest domains using virtual I/O. In production, customers typically use multiple domains with I/O and service roles to eliminate single points of failure: guest domains have virtual disk and virtual devices provisioned from more than one service domain, so failure of a service domain or I/O path or device doesn't result in an application outage. This is also used for "rolling upgrades" in which service domains are upgraded one at a time while their guests continue to operate without disruption. (It should be noted that resiliency to I/O device failures can also be provided by the single control domain, using multi-path I/O) In this type of deployment, control, I/O, and service domains are used for virtualization infrastructure, while applications run in guest domains. Changing application deployment patterns The above model has been widely and successfully used, but more configuration options are available now. Servers got bigger than the original T2000 class machines with 2 I/O busses, so there is more I/O capacity that can be used for applications. Increased T-series server capacity made it attractive to run more vertical applications, such as databases, with higher resource requirements than the "light" applications originally seen. This made it attractive to run applications in I/O domains so they could get bare-metal native I/O performance. This is leveraged by the SPARC SuperCluster engineered system, announced a year ago at Oracle OpenWorld. In SPARC SuperCluster, I/O domains are used for high performance applications, with native I/O performance for disk and network and optimized access to the Infiniband fabric. Another technical enhancement is the introduction of Direct I/O (DIO) and Single Root I/O Virtualization (SR-IOV), which make it possible to give domains direct connections and native I/O performance for selected I/O devices. A domain with either a DIO or SR-IOV device is an I/O domain. In summary: not all I/O domains own PCI complexes, and there are increasingly more I/O domains that are not service domains. They use their I/O connectivity for performance for their own applications. However, there are some limitations and considerations: at this time, a domain using physical I/O cannot be live-migrated to another server. There is also a need to plan for security and introducing unneeded dependencies: if an I/O domain is also a service domain providing virtual I/O go guests, it has the ability to affect the correct operation of its client guest domains. This is even more relevant for the control domain. where the ldm has to be protected from unauthorized (or even mistaken) use that would affect other domains. As a general rule, running applications in the service domain or the control domain should be avoided. To recap: Guest domains with virtual I/O still provide the greatest operational flexibility, including features like live migration. I/O domains can be used for applications with high performance requirements. This is used to great effect in SPARC SuperCluster and in general T4 deployments. Direct I/O (DIO) and Single Root I/O Virtualization (SR-IOV) make this more attractive by giving direct I/O access to more domains. Service domains should in general not be used for applications, because compromised security in the domain, or an outage, can affect other domains that depend on it. This concern can be mitigated by providing guests' their virtual I/O from more than one service domain, so an interruption of service in the service domain does not cause an application outage. The control domain should in general not be used to run applications, for the same reason. SPARC SuperCluster use the control domain for applications, but it is an exception: it's not a general purpose environment; it's an engineered system with specifically configured applications and optimization for optimal performance. These are recommended "best practices" based on conversations with a number of Oracle architects. Keep in mind that "one size does not fit all", so you should evaluate these practices in the context of your own requirements. Summary Higher capacity T-series servers have made it more attractive to use them for applications with high resource requirements. New deployment models permit native I/O performance for demanding applications by running them in I/O domains with direct access to their devices. This is leveraged in SPARC SuperCluster, and can be leveraged in T-series servers to provision high-performance applications running in domains. Carefully planned, this can be used to provide higher performance for critical applications.
