  • 5 Best Practices - Laying the Foundation for WebCenter Projects

    - by Kellsey Ruppel
    Today’s guest post comes from Oracle WebCenter expert John Brunswick. John specializes in enterprise portal and content management solutions and actively contributes to the enterprise software business community and has authored a series of articles about optimal business involvement in portal, business process management and SOA development, examining ways of helping organizations move away from monolithic application development. We’re happy to have John join us today! Maximizing success with Oracle WebCenter portal requires a strategic understanding of Oracle WebCenter capabilities.  The following best practices enable the creation of portal solutions with minimal resource overhead, while offering the greatest flexibility for progressive elaboration. They are inherently project agnostic, enabling a strong foundation for future growth and an expedient return on your investment in the platform.  If you are able to embrace even only a few of these practices, you will materially improve your deployment capability with WebCenter. 1. Segment Duties Around 3Cs - Content, Collaboration and Contextual Data "Agility" is one of the most common business benefits touted by modern web platforms.  It sounds good - who doesn't want to be Agile, right?  How exactly IT organizations go about supplying agility to their business counterparts often lacks definition - hamstrung by ambiguity. Ultimately, businesses want to benefit from reduced development time to deliver a solution to a particular constituent, which is augmented by as much self-service as possible to develop and manage the solution directly. All done in the absence of direct IT involvement. With Oracle WebCenter's depth in the areas of content management, pallet of native collaborative services, enterprise mashup capability and delegated administration, it is very possible to execute on this business vision at a technical level. To realize the benefits of the platform depth we can think of Oracle WebCenter's segmentation of duties along the lines of the 3 Cs - Content, Collaboration and Contextual Data.  All three of which can have their foundations developed by IT, then provisioned to the business on a per role basis. Content – Oracle WebCenter benefits from an extremely mature content repository.  Work flow, audit, notification, office integration and conversion capabilities for documents (HTML & PDF) make this a haven for business users to take control of content within external and internal portals, custom applications and web sites.  When deploying WebCenter portal take time to think of areas in which IT can provide the "harness" for content to reside, then allow the business to manage any content items within the site, using the content foundation to ensure compliance with business rules and process.  This frees IT to work on more mission critical challenges and allows the business to respond in short order to emerging market needs. Collaboration – Native collaborative services and WebCenter spaces are a perfect match for business users who are looking to enable document sharing, discussions and social networking.  The ability to deploy the services is granular and on the basis of roles scoped to given areas of the system - much like the first C “content”.  This enables business analysts to design the roles required and IT to provision with peace of mind that users leveraging the collaborative services are only able to do so in explicitly designated areas of a site. Bottom line - business will not need to wait for IT, but cannot go outside of the scope that has been defined based on their roles. Contextual Data – Collaborative capabilities are most powerful when included within the context of business data.  The ability to supply business users with decision shaping data that they can include in various parts of a portal or portals, just as they would with content items, is one of the most powerful aspects of Oracle WebCenter.  Imagine a discussion about new store selection for a retail chain that re-purposes existing information from business intelligence services about various potential locations and or custom backend systems - presenting it directly in the context of the discussion.  If there are some data sources that are preexisting in your enterprise take a look at how they can be made into discrete offerings within the portal, then scoped to given business user roles for inclusion within collaborative activities. 2. Think Generically, Execute Specifically Constructs.  Anyone who has spent much time around me knows that I am obsessed with this word.  Why? Because Constructs offer immense power - more than APIs, Web Services or other technical capability. Constructs offer organizations the ability to leverage a platform's native characteristics to offer substantial business functionality - without writing code.  This concept becomes more powerful with the additional understanding of the concepts from the platform that an organization learns over time.  Let's take a look at an example of where an Oracle WebCenter construct can substantially reduce the time to get a subscription-based site out the door and into the hands of the end consumer. Imagine a site that allows members to subscribe to specific disciplines to access information and application data around that various discipline.  A space is a collection of secured pages within Oracle WebCenter.  Spaces are not only secured, but also default content stored within it to be scoped automatically to that space. Taking this a step further, Oracle WebCenter’s Activity Stream surfaces events, discussions and other activities that are scoped to the given user on the basis of their space affiliations.  In order to have a portal that would allow users to "subscribe" to information around various disciplines - spaces could be used out of the box to achieve this capability and without using any APIs or low level technical work to achieve this. 3. Make Governance Work for You Imagine driving down the street without the painted lines on the road.  The rules of the road are so ingrained in our minds, we often do not think about the process, but seemingly mundane lane markers are critical enablers. Lane markers allow us to travel at speeds that would be impossible if not for the agreed upon direction of flow. Additionally and more importantly, it allows people to act autonomously - going where they please at any given time. The return on the investment for mobility is high enough for people to buy into globally agreed up governance processes. In Oracle WebCenter we can use similar enablers to lane markers.  Our goal should be to enable the flow of information and provide end users with the ability to arrive at business solutions as needed, not on the basis of cumbersome processes that cannot meet the business needs in a timely fashion. How do we do this? Just as with "Segmentation of Duties" Oracle WebCenter technologies offer the opportunity to compartmentalize various business initiatives from each other within the system due to constructs and security that are available to use within the platform. For instance, when a WebCenter space is created, any content added within that space by default will be secured to that particular space and inherits meta data that is associated with a folder created for the space. Oracle WebCenter content uses meta data to support a broad range of rich ECM functionality and can automatically impart retention, workflow and other policies automatically on the basis of what has been defaulted for that space. Depending on your business needs, this paradigm will also extend to sub sections of a space, offering some interesting possibilities to enable automated management around content. An example may be press releases within a particular area of an extranet that require a five year retention period and need to the reviewed by marketing and legal before release.  The underlying content system will transparently take care of this process on the basis of the above rules, enabling peace of mind over unstructured data - which could otherwise become overwhelming. 4. Make Your First Project Your Second Imagine if Michael Phelps was competing in a swimming championship, but told right before his race that he had to use a brand new stroke.  There is no doubt that Michael is an outstanding swimmer, but chances are that he would like to have some time to get acquainted with the new stroke. New technologies should not be treated any differently.  Before jumping into the deep end it helps to take time to get to know the new approach - even though you may have been swimming thousands of times before. To quickly get a handle on Oracle WebCenter capabilities it can be helpful to deploy a sandbox for the team to use to share project documents, discussions and announcements in an effort to help the actual deployment get under way, while increasing everyone’s knowledge of the platform and its functionality that may be helpful down the road. Oracle Technology Network has made a pre-configured virtual machine available for download that can be a great starting point for this exercise. 5. Get to Know the Community If you are reading this blog post you have most certainly faced a software decision or challenge that was solved on the basis of a small piece of missing critical information - which took substantial research to discover.  Chances were also good that somewhere, someone had already come across this information and would have been excited to share it. There is no denying the power of passionate, connected users, sharing key tips around technology.  The Oracle WebCenter brand has a rich heritage that includes industry-leading technology and practitioners.  With the new Oracle WebCenter brand, opportunities to connect with these experts has become easier. Oracle WebCenter Blog Oracle Social Enterprise LinkedIn WebCenter Group Oracle WebCenter Twitter Oracle WebCenter Facebook Oracle User Groups Additionally, there are various Oracle WebCenter related blogs by an excellent grouping of services partners.

  • How can I provide secure web content to mobile devices that can't access an intranet?

    - by evanmcd
    I'm working with a client on development web content for their intranet. We want users to be able to access a version of the content on their mobile devices, but most of them don't have the VPN capability to get on to their intranet. I'm wondering if anyone has had experience with this and can recommend a solution. One other thing to consider is that the content is not mission critically secure. If someone outside the company gained access to it, it would not represent a major issue, only a minor annoyance. Thanks for any advice.

  • Is it possible to change the content database of an existing SharePoint '07 web app?

    - by mcjabberz
    Disclaimer: I'm very much an accidental SharePoint admin so I greatly appreciate your patience. My SharePoint farm's database server is EOL and about to die. I have managed to get the config database (SharePoint_Config) moved over to the new database server and even managed to get the Central Administration site to use the new database server. I have even added the new database server to the farm as a content database server. My problem right now is with the web app's content database (WSS_Content). I already have a copy of the content database setup and ready to go on the new database server but, for the life of me, I can't figure out how to change the SharePoint web app's database over to it. Is this even possible? If so, how would I do it? If not, would I have to create a new web app and then restore (and overwrite) its WSS_Content database with my existing one?

  • What am I (a beginner) losing, by choosing Cherokee over Apache for serving dynamic content?

    - by Bad Learner
    I am a complete beginner and am planning to setup a photo sharing site. This is the setup I am planning, basically for a start - - Cherokee (instead of Apache) for serving dynamic content (python-based application), and Nginx for serving static files. Since, I am a beginner, what have I, to lose? So, can someone, from your experience, please tell me, what I'd lose by choosing Cherokee over Apache for serving dynamic content in PHP/Python/whatever? Anything other than the fact that there's lot of documentation, many people who can help when there's an issue etc as Apache is well established and the most popular web server? Again, my intention is not to spurt a flame war here. Just wanted to know if Cherokee would be better than Apache in terms of performance, reliability, and speed, when it matters (peak load times). Also, I heard it's a lot faster than Apache in serving dynamic content, is it true?

  • preparing to migrate MOSS 2007 SP1 content into new server with MOSS 2007 SP2 with the same server n

    - by Albert Widjaja
    To All Experts here, I'd like to perform a MOSS server content migration from the existing single instance server (SQL Server 2008, Windows Server 2008, SharePoint 2007 SP1) all in one and by maintaining the server name only, here's what I had in my migration plan document outline: I have created the new Windows Server 2008 R2 + SQL Server 2008 SP1 and MOSS 2007 SP2 after that: Backup MOSS_ContentDB from SQL Server 2008 SSMS (does this enough to cover all top level sites and its content in the library and doc. repository ?) Backup all top level sites from CA site using the CA Sites backup and restore tools. turn off the old MOSSDEV01 (current server) rename the existing server (TempServ01) into MOSSDEV01 (so that the user bookmark and other link inside MOSS site still working) perform restore of the DB restore the site collection and its content from the backup is that the correct way to do it ? I haven't execute the server configuration wizard to create the same port number of the SSP, CA and the SQL Server DB yet. Any idea and suggestion would be greatly appreciated Thanks.

  • Do CDNs actually dump the data to the client or pass the URL of the content?

    - by zengr
    I am curious, say for example: Facebook is the client of Akamai CDN. So, now when I login to my FaceBook page, I see all the content (vid, image, text etc) and I click on a video to view it. Now, Facebook is the client to Akami to get the content. So, when a request is made from Facebook to Akami, does Akamai dump the vid/image from their data centers to Facebook's data centers where they reside for a while (depending on their heuristics) and flushed after some time? Or, I see that video (stream it) directly from Akamai's server? UPDATE Data resides in CDN permanently (agreed), but is a copy of the content sent to Facebook's data centers too

  • How to setup RAID 1 with Intel RST on an existing Windows 7 system?

    - by instcode
    I'd like to setup RAID-1 using Intel Rapid Storage Technology on my Windows 7 64-bit system. I have an 1TB SATA HDD with Windows 7 system installed on the first primary partition (leftmost, ~200GB). The rest of this HDD is unallocated (~800GB). I bought another 2TB SATA, then created a primary partition (leftmost, ~500GB) and filled my data in. The rest of this HDD is unallocated (~1.5TB). A quick disk layout (XXX is the unallocated region): HDD1 (1TB): [ 200GB C:\ SYSTEM | XXXXXXXXXXXX ] HDD2 (2TB): [ 500GB Z:\ PROGRAM | XXXXXXXXXXXXXXXXXXXXXX ] Now, I want to create a 500GB RAID-1 partition (I'm not sure if using "partition" is correct here) on the rightmost of the 2 HDDs above without losing any existing data from both disks. Here is the expected layout: HDD1 (1TB): [ 200GB C:\ SYSTEM | XXXXXX | 500GB D:\ DATA - RAID-1 ] HDD2 (2TB): [ 500GB Z:\ PROGRAM | XXXXXXXXXXXXXXXX | 500GB D:\ DATA RAID-1] Let's not concern about data lost, is it possible to have that final layout using Intel RST? Previously, I tried this layout using dynamic disk & software RAID from Windows and it worked as expected, however, it's quite ugly in resynching after an OS failure that I don't want. If yes, is there a way to keep the data on existing partitions untouched or, at least, it should keep the SYSTEM partition safe (I'm okay if the PROGRAM partition has to be gone.)? Well, are there any strict/special steps I should follow when using the Intel RST manager in order to achieve that? If none of those questions above are "Yes", could you please suggest some other possible layouts that leave the C:SYSTEM partition untouched?

  • Have .cmd in startup wait for system wide startup to run.

    - by Dan
    On a computer I'm not an administrator on, there is a startup file (.cmd file in C:\Documents and Settings\All Users\Start Menu\Programs\Startup) for all users. It does several things I don't like, so I have created my own .cmd file which I have placed in C:\Documents and Settings\[user]\Start Menu\Programs\Startup. I want my code to run after the system wide, because my program first undoes the network mappings the system wide file did, and then replaces it with my own network mappings. How can I make my program wait and start as soon as the system wide one is done? (I cannot remove or edit the system wide file). Thanks EDIT: The time that the system wide file takes to runs varies and I would like my file to run right after. The "If Exists" method seems a little to contingent since the system wide script can change or a file could be moved. I am hoping to give my script to a few of my coworkers, so hoping to have it work without me having to update anything. Also, being a linux guy, I don't know cmd code, so please write out any coding suggestions.

  • How can I disable HTML5 content in popular browsers like Firefox and Chrome?

    - by HRJ
    The bad thing about Flash video was that it required a third-party plugin to play the content. The good thing was I could select which content to play; using the click-to-play feature in Firefox and Chrome. But now that HTML5 video is getting popular, I see a lot of ads popping into view again. They are not only a distraction, they hog resources on my computer and make the fans spin full speed. Is there a way to disable HTML5 audio/video content by default, and enable it only selectively?

  • SCCM 2012: How to properly update the content of an application?

    - by Omnomnomnom
    I recently set up a new SCCM 2012 environment at my workplace and now we are creating our applications for distribution. Some applications are set up using a script. When during testing, something was not right and the content of the application needs to be changed. The distribution point keeps on serving the old content to the clients. I was wondering what the proper procedure is for updating the DP's when the content of an application changes. I have tried redistributing to the distribution points and deleting old revisions but to no avail.

  • Which open source/free CMSs allow for staging content changes before putting live?

    - by elliot100
    I'm not sure that I've phrased the question all that well. What I'm really looking for is a feature of CMSs where content changes are made on a restricted access 'staging/preview' site, before being published to the live external site. The open source/free CMSs I've looked at so far (Textpattern, WordPress, Movable Type) don't seem to allow this, as far as I can see. Although they allow new content to be saved as draft/pending, viewable by users with appropriate privileges, this doesn't work with changes to existing content -- a post/page can't be live and also have a new version pending. (Do correct me if I'm wrong). I realise it should be possible to do this by making all changes on a staging site, and then replicating the contents of that database to a separate live site manually, but am looking for something a little more elegant. Edit: Just to clarify, both systems which involve synchronising a live database with a staging database systems which offer live/staging views of a single database would be of interest. Am sure I have seen both approaches in commercial/proprietary CMSs.

  • What can cause the system to freeze in a way where even the reset button takes a long time to react?

    - by ThiefMaster
    What can be the reason for system freezes that are so "hard" that even the hardware reset button takes about 3 seconds until it actually resets the system (and then it actually powers down and up again instead of doing a "clean" hard reset like when pressing it during a normally running system). Since it initially happened mainly while playing videos from YouTube I suspected the graphics card - however, I replaced it recently and it did not change it. It still happens from time to time (and sometimes more often, like a few times times in the last few hours). The system is running Windows 7 - but I don't think this matters since I don't think any software, not even the OS, can actually affect the reset button's behaviour. The PC is not overheated and the freezes happen randomly. There is also no malware on the system. The CPU is an Intel Core i7-920 on a Gigabyte EX58-UD5 mainboard. What could be the cause for this problem? Faulty RAM? I did not run a full memtest86 check yet, but I wonder if there is a more likely issue than faulty RAM - checking 12G of ram does take some time after all! There are no entries in the event log - but that's what I expected since the system freezes so hard that I doubt it has time to write anything to any log.

  • BI and EPM Landscape

    - by frank.buytendijk
    Most of my blog entries are not about Oracle products, and most of the latest entries are about topics such as IT strategy and enterprise architecture. However, given my background at Gartner, and at Hyperion, I still keep a close eye on what's happening in BI and EPM. One important reason is that I believe there is significant competitive value for organizations getting BI and EPM right. Davenport and Harris wrote a great book called "Competing on Analytics", in which they explain this in a very engaging and convincing way. At Oracle we have defined the concept of "management excellence" that outlines what organizations have to do to keep or create a competitive edge. It's not only in the business processes, but also in the management processes. Recently, Gartner published its 2009 market shares report for BI, Analytics, and Performance Management. Gartner identifies the same three segments that Oracle does: (1) CPM Suites (Oracle refers not to Corporate Performance Management, but Enterprise Performance Management), (2) BI Platform, and (3) Analytic Applications & Performance Management. According to Gartner, Oracle's share is increasing with revenue growing by more than 5%. Oracle currently holds the #2 market share position in the overall BI Software space based on total BI software revenue. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 Gartner has ranked Oracle as #1 in the CPM Suites worldwide sub-segment based on total BI software revenue, and Oracle is gaining share with revenue growing by more than 6% in 2009. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 The Analytic Applications & Performance Management subsegment is more fragmented. It has for instance a very large "Other Vendors" category. The largest player traditionally is SAS. Analytic Applications are often meant for very specific analytic needs in very specific industry sectors. According to Gartner, from the large vendors, again Oracle is the one who is gaining the most share - with total BI software revenue growth close to 15% in 2009. Source: Gartner Dataquest Market Share: Business Intelligence, Analytics and Performance Management Software, Worldwide, 2009; Dan Sommer and Bhavish Sood; Apr 2010 I believe this shows Oracle's integration strategy is working. In fact, integration actually is the innovation. BI and EPM have been silo technology platforms and application suites way too long. Management and measuring performance should be very closely linked to strategy execution, which is the domain of other business application areas such as CRM, ERP, and Supply Chain. BI and EPM are not about "making better decisions" anymore, but are part of a tangible action framework. Furthermore, organizations are getting more serious about ecosystem thinking. They do not evaluate single tools anymore for different application areas, but buy into a complete ecosystem of hardware, software and services. The best ecosystem is the one that offers the most options, in environments where the uncertainty is high and investments are hard to reverse. The key to successfully managing such an environment is middleware, and BI and EPM become increasingly middleware intensive. In fact, given the horizontal nature of BI and EPM, sitting on top of all business functions and applications, you could call them "upperware". Many are active in the BI and EPM space. Big players can offer a lot, but there are always many areas that are covered by specialty vendors. Oracle openly embraces those technologies within the ecosystem as well. Complete, open and integrated still accurately describes the Oracle product strategy. frank

  • How much system and business analysis should a programmer be reasonably expected to do?

    - by Rahul
    In most places I have worked for, there were no formal System or Business Analysts and the programmers were expected to perform both the roles. One had to understand all the subsystems and their interdependencies inside out. Further, one was also supposed to have a thorough knowledge of the business logic of the applications and interact directly with the users to gather requirements, answer their queries etc. In my current job, for ex, I spend about 70% time doing system analysis and only 30% time programming. I consider myself a good programmer but struggle with developing a good understanding of the business rules of a complex application. Often, this creates a handicap because while I can write efficient algorithms and thread-safe code, I lose out to guys who may be average programmers but have a much better understanding of the business processes. So I want to know - How much business and systems knowledge should a programmer have ? - How does one go about getting this knowledge in an immensely complex software system (e.g. trading applications) with several interdependent business processes but poorly documented business rules.

  • ASP.NET MVC 2 Hosting :: MVC2 deploy - Could not load file or assembly 'System.Web.MVC, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

    - by mbridge
    A new MVC 2 project worked on my local machine but when it was deployed to the test server it gave the error 'Could not load file or assembly 'System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.' I have the full Visual Studio 2010 installed on my local machine but just the .NET 4 framework installed on the test servers. It seems the MVC assemblies do not come with .NET 4 framework itself so how to make MVC 2 work on the test servers? When I installed Visual Studio 2010 on my local machine it came with all the fruit included (.NET4 framework, MVC2 etc) so the System.Web.Mvc.dll can be found in my machine's GAC (C:\Windows\assembly). However, since there is no need to bloat the web servers only the plain old .NET4 framework has been installed on the test servers. This does NOT include the MVC assembly and that is why it cannot be found by the web application. You need this assembly to be on your web servers that you are deploying to but you want to avoid having to copy them into the GAC manually and doing all that gacutil mess or maybe you don't have access to your servers if they are hosted by provider. Solution You need to make the System.Web.Mvc assembly bin deployable... okay that doesn't sound easy but here is how to do it for the necessary MVC references: Simply right click the reference and select 'Properties' Then change 'Copy Local' to 'True': Note If your server has .NET 3.5 sp1 installed the new(ish) assemblies System.Web.Routing and System.Web.Abstractions will already be in the GAC. If you had previously deployed an MVC 1 application to a .NET 3.5 server you may remember having to deploy the other two assemblies too. Since MVC2 requires at least .NET 3.5 sp1 you will not need to worry about these assemblies, just System.Web.Mvc

  • What "file system" is supported by Windows and Linux?

    - by Skiroid
    I'm setting up a media centre for my living room so that I'm able to watch downloaded films and TV shows on the big screen. The media centre is an old small computer which will have XBMCbuntu 12 installed on it. Right now, the media centre has a 300 GB HDD partitioned into two: 1) Ext4 50 GB (where I'll install the OS) 2) swap 6 GB (swap area) I'm wanting a third partition which I can store all my media on to. This partition will fill the rest of my HDD. Although, I'm stuck on which file system I should set it to. I need the file system to be fully compatible with Windows as I'm going to be removing the HDD from the media centre and plugging it into my main PC, running Windows 8, to transfer the media onto it. I can't transfer over Wi-Fi as the media centre won't be connected to the Internet. My options are: Ext4 journaling, Ext3 journaling, Ext2 journaling, ReiserFS journaling, btrfs journaling, JFS journaling, XFS journaling, FAT16 and FAT32. I know that FAT32 is compatible with Windows but it can only hold files that are 4 GB or less and my films are well over 4 GB. Some more than 10 GB. Is there a file system I can use which is supported by Linux and pops up under Computer in Windows?

  • Emulate Historical Figures i.e. Einstein - Is this possible using linguistic logic for my http://www.ustimeline.com Education System

    - by Johnnylight
    After hearing about the success of IBM's Watson I started thinking perhaps emulating human language is now possible? My goal is to create Virtual Historical characters to represent the main characters in my Adventur-Cation The Great American Adventure program such as Einstein or Crazy Horse. The goal is to build an intelligent system capable of indexing the internet and storing the data using a schema using modern knowledge on linguistic theory (phonemes, morphemes, syntax) to build a system capable to returning a semantically sound response very similar to the response made by the same person if still alive today. The goal would be to use the same engine/system for all characters. Each characters would have their own digital representation and voice, and would organize data differently based on tags/keywords stored about the individual. Imagine a Max Headroom Einstein. Based on the success of Watson, I believe something like this may now be possible. Would be an interesting way to study history and would be a vehicle of entertainment as well. Can anyone confirm if this has already been attempted? Is anyone interested in exploring this using Cognitive Science, Psychology, Artificial Intelligence, Historical data captured on the internet, and Linguistic theory?

    - by racerror
    My brand new system is randomly freezing and I don't know how to debug the issue. System: AMD A10-5800k Asus F2A85-M motherboard Integrated Radeon HD 7660D 8gb Samsung ddr3 1600 Ubuntu 12.10 Gnome shell / Unity (issue exists in both) xorg.conf (relevant parts): Section "Device" Identifier "aticonfig-Device[0]-0" Driver "fglrx" BusID "PCI:0:1:0" Option "TexturedVideoSync" "on" Option "UseFastTLS" "2" EndSection Section "Screen" Identifier "aticonfig-Screen[0]-0" Device "aticonfig-Device[0]-0" Monitor "Monitor0" DefaultDepth 24 Option "UseEDID" "False" Option "ExactModeTimingsDVI" "True" Option "NoBandWidthTest" "true" Option "ModeValidation" "AllowNon60hzmodesDFPModes, NoEDIDDFPMaxSizeCheck, NoVertRefreshCheck, NoHorizSyncCheck, NoDFPNativeResolutionCheck, NoMaxSizeCheck, NoMaxPClkCheck, NoEDIDModes" Option "UseEDIDDPI" "False" Option "UseEDIDFreqs" "0" Option "NoLogo" "True" Option "Coolbits" "1" Option "metamodes" "DFP-0: 2560x1440_60 +0+0" SubSection "Display" Depth 24 Modes "2560x1440" EndSubSection I ran memtest on my ram and it checks out fine. I have tried using the latest fglrx and fglrx-beta. I have loaded 3.6.x kernel. I do not see anything relevant in dmesg, kern.log, syslog, .xsession-errors or Xorg.log. I cannot ssh into the machine when frozen from another machine. I know that system resources not being stressed when the crashes happen. It seems that video and any gaming (very simple graphics games) contribute to the freezes most frequently. However, I have experienced the crash before when just using Chrome. I suspect the crashes are xorg/fglrx related, but I have no evidence to back that up. Where should I look? What should I grep for? What should I try next?

  • Algorithms for Data Redundancy and Failover for distributed storage system?

    - by kennetham
    I'm building a distributed storage system that works with different storage sizes. For instance, my storage devices have sizes of 50GB, 70GB, 150GB, 250GB, 1000GB, 5 storage systems in one system. My application will store any files to the storage system. Question: How can I build a distributed storage with the idea of data redundancy and fail-over to store documents, videos, any type of files at the same time ensuring that should one of any storage devices fail, there would be another copy of these files on another storage device. However, the concern is, 50GB of storage can only store this maximum number of files as compared to 70GB, 150GB etc. With one storage in mind, bringing 5 storage systems like a cloud storage, is there any logical way to distribute or store the files through my application? How do I ensure data redundancy through different storage sizes? Is there any algorithm to collate multiple blob files into a single file archive? What is the best solution for one cloud storage with multiple different storage sizes? I open this topic with the objective of discussing the best way to implement this idea, assuming simplicity, what are the issues of this implementation, performance measurements and discussion of the limitations.

  • Storing images in file system and returning URLs or virtually resizing and returning byte arrays?

    - by ismaelf
    I need to create a REST web service to manage user submitted images and displaying them all in a website. There are multiple websites that are going to use this service to manage and display images. The requirements are to have 5 pre-defined image sizes available. The 2 options I see are the following: The web service will create the 5 images, store them in the file system and and store the URL's in the database when the user submits the image. When the image is requested, the web service will return an array of URLs. I see this option to be a little hard on the hard drive. The estimates are 10,000 users per site, and lets say, 100 sites. The heavy processing will be done when the user submits the image and each image is going to be pulled from the File System. The web service will store just the image that the user submits in the file system and it's URL in the database. When the user request images, the web service will get the info from the DB, load the image on memory, create its 5 instances and return an object with 5 image arrays (I will probably cache the arrays). This option is harder on the processor and memory. The heavy processing will be done when the images get requested. A plus I see for option 2 is that it will give me the option to rewrite the URL of the image and make them site dependent (prettier) than having a image repository for all websites. But this is not a big deal. What do you think of these options? Do you have any other suggestions?

Or is there a different installer for servers?

  • Extending GroupPrincipal and Members property

    - by Paolo Tedesco
    I want to extend the GroupPrincipal class to handle some custom properties: using System.DirectoryServices.AccountManagement; [DirectoryRdnPrefix("CN")] [DirectoryObjectClass("group")] public class MyGroupPrincipal : GroupPrincipal { // ... } How could I override the Members property for MyGroupPrincipal so that if it has a member that is a group an instance of MyGroupPrincipal and not of GroupPrincipal is returned? I would like to write e.g. MyGroupPrincipal group = GetGroup(); foreach (var m in group.Members) { if (m is MyGroupPrincipal) { // always fails: m is a normal GroupPrincipal // do something } }
