• BI Applications overview

  - by sv744

  Welcome to Oracle BI applications blog! This blog will talk about various features, general roadmap, description of functionality and implementation steps related to Oracle BI applications. In the first post we start with an overview of the BI apps and will delve deeper into some of the topics below in the upcoming weeks and months. If there are other topics you would like us to talk about, pl feel free to provide feedback on that. The Oracle BI applications are a set of pre-built applications that enable pervasive BI by providing role-based insight for each functional area, including sales, service, marketing, contact center, finance, supplier/supply chain, HR/workforce, and executive management. For example, Sales Analytics includes role-based applications for sales executives, sales management, as well as front-line sales reps, each of whom have different needs. The applications integrate and transform data from a range of enterprise sources—including Siebel, Oracle, PeopleSoft, SAP, and others—into actionable intelligence for each business function and user role. This blog  starts with the key benefits and characteristics of Oracle BI applications. In a series of subsequent blogs, each of these points will be explained in detail. Why BI apps? Demonstrate the value of BI to a business user, show reports / dashboards / model that can answer their business questions as part of the sales cycle. Demonstrate technical feasibility of BI project and significantly lower risk and improve success Build Vs Buy benefit Don’t have to start with a blank sheet of paper. Help consolidate disparate systems Data integration in M&A situations Insulate BI consumers from changes in the OLTP Present OLTP data and highlight issues of poor data / missing data – and improve data quality and accuracy Prebuilt Integrations BI apps support prebuilt integrations against leading ERP sources: Fusion Applications, E- Business Suite, Peoplesoft, JD Edwards, Siebel, SAP Co-developed with inputs from functional experts in BI and Applications teams. Out of the box dimensional model to source model mappings Multi source and Multi Instance support Rich Data Model    BI apps have a very rich dimensionsal data model built over 10 years that incorporates best practises from BI modeling perspective as well as reflect the source system complexities  Thanks for reading a long post, and be on the lookout for future posts.  We will look forward to your valuable feedback on these topics as well as suggestions on what other topics would you like us to cover. I Conformed dimensional model across all business subject areas allows cross functional reporting, e.g. customer / supplier 360 Over 360 fact tables across 7 product areas CRM – 145, SCM – 47, Financials – 28, Procurement – 20, HCM – 27, Projects – 18, Campus Solutions – 21, PLM - 56 Supported by 300 physical dimensions Support for extensive calendars; Gregorian, enterprise and ledger based Conformed data model and metrics for real time vs warehouse based reporting  Multi-tenant enabled Extensive BI related transformations BI apps ETL and data integration support various transformations required for dimensional models and reporting requirements. All these have been distilled into common patterns and abstracted logic which can be readily reused across different modules Slowly Changing Dimension support Hierarchy flattening support Row / Column Hybrid Hierarchy Flattening As Is vs. As Was hierarchy support Currency Conversion :-  Support for 3 corporate, CRM, ledger and transaction currencies UOM conversion Internationalization / Localization Dynamic Data translations Code standardization (Domains) Historical Snapshots Cycle and process lifecycle computations Balance Facts Equalization of GL accounting chartfields/segments Standardized values for categorizing GL accounts Reconciliation between GL and subledgers to track accounted/transferred/posted transactions to GL Materialization of data only available through costly and complex APIs e.g. Fusion Payroll, EBS / Fusion Accruals Complex event Interpretation of source data – E.g. o    What constitutes a transfer o    Deriving supervisors via position hierarchy o    Deriving primary assignment in PSFT o    Categorizing and transposition to measures of Payroll Balances to specific metrics to support side by side comparison of measures of for example Fixed Salary, Variable Salary, Tax, Bonus, Overtime Payments. o    Counting of Events – E.g. converting events to fact counters so that for example the number of hires can easily be added up and compared alongside the total transfers and terminations. Multi pass processing of multiple sources e.g. headcount, salary, promotion, performance to allow side to side comparison. Adding value to data to aid analysis through banding, additional domain classifications and groupings to allow higher level analytical reporting and data discovery Calculation of complex measures examples: o    COGs, DSO, DPO, Inventory turns  etc o    Transfers within a Hierarchy or out of / into a hierarchy relative to view point in hierarchy. Configurability and Extensibility support  BI apps offer support for extensibility for various entities as automated extensibility or part of extension methodology Key Flex fields and Descriptive Flex support  Extensible attribute support (JDE)  Conformed Domains ETL Architecture BI apps offer a modular adapter architecture which allows support of multiple product lines into a single conformed model Multi Source Multi Technology Orchestration – creates load plan taking into account task dependencies and customers deployment to generate a plan based on a customers of multiple complex etl tasks Plan optimization allowing parallel ETL tasks Oracle: Bit map indexes and partition management High availability support    Follow the sun support. TCO BI apps support several utilities / capabilities that help with overall total cost of ownership and ensure a rapid implementation Improved cost of ownership – lower cost to deploy On-going support for new versions of the source application Task based setups flows Data Lineage Functional setup performed in Web UI by Functional person Configuration Test to Production support Security BI apps support both data and object security enabling implementations to quickly configure the application as per the reporting security needs Fine grain object security at report / dashboard and presentation catalog level Data Security integration with source systems  Extensible to support external data security rules Extensive Set of KPIs Over 7000 base and derived metrics across all modules Time series calculations (YoY, % growth etc) Common Currency and UOM reporting Cross subject area KPIs (analyzing HR vs GL data, drill from GL to AP/AR, etc) Prebuilt reports and dashboards 3000+ prebuilt reports supporting a large number of industries Hundreds of role based dashboards Dynamic currency conversion at dashboard level Highly tuned Performance The BI apps have been tuned over the years for both a very performant ETL and dashboard performance. The applications use best practises and advanced database features to enable the best possible performance. Optimized data model for BI and analytic queries Prebuilt aggregates& the ability for customers to create their own aggregates easily on warehouse facts allows for scalable end user performance Incremental extracts and loads Incremental Aggregate build Automatic table index and statistics management Parallel ETL loads Source system deletes handling Low latency extract with Golden Gate Micro ETL support Bitmap Indexes Partitioning support Modularized deployment, start small and add other subject areas seamlessly Source Specfic Staging and Real Time Schema Support for source specific operational reporting schema for EBS, PSFT, Siebel and JDE Application Integrations The BI apps also allow for integration with source systems as well as other applications that provide value add through BI and enable BI consumption during operational decision making Embedded dashboards for Fusion, EBS and Siebel applications Action Link support Marketing Segmentation Sales Predictor Dashboard Territory Management External Integrations The BI apps data integration choices include support for loading extenral data External data enrichment choices : UNSPSC, Item class etc. Extensible Spend Classification Broad Deployment Choices Exalytics support Databases :  Oracle, Exadata, Teradata, DB2, MSSQL ETL tool of choice : ODI (coming), Informatica Extensible and Customizable Extensible architecture and Methodology to add custom and external content Upgradable across releases

• Help with Collision of spawned object(postion fixed) with objects that there are translating on screen

  - by Amrutha

  Hey guys I am creating a game using Corona SDK and so coding it in Lua. So there are 2 separate functions, To translate the hit objects and change their color when they are tapped The link below is the code I am using to for the first function http://developer.anscamobile.com/sample-code/fishies Spawn objects that will hit the translating objects on collision. Alos on collision the spawned object disappears and the translating object bears a color(indicating the collision). In addition the size of this spawned object is dependent on i/p volume level. The function I have written is as follows, --VOICE INPUT CODE local r = media.newRecording() r:startRecording() r:startTuner() --local function newBar() -- local bar = display.newLine( 0, 0, 1, 0 ) -- bar:setColor( 0, 55, 100, 20 ) -- bar.width = 5 -- bar.y=400 -- bar.x=20 -- return bar --end local c1 = display.newImage("str-minion-small.png") c1.isVisible=false local c2 = display.newImage("str-minion-mid.png") c2.isVisible=false local c3 = display.newImage("str-minion-big.png") c3.isVisible=false --SPAWNING local function spawnDisk( event ) local phase = event.phase local volumeBar = display.newLine( 0, 0, 1, 0 ) volumeBar.y = 400 volumeBar.x = 20 -- volumeBar.isVisible=false local v = 20*math.log(r:getTunerVolume()) local MINTHRESH = 30 local LEFTMARGIN = 20 local v2 = MINTHRESH + math.max (v, -MINTHRESH) v2 = (display.contentWidth - 1 * LEFTMARGIN ) * v2 / MINTHRESH volumeBar.xScale = math.max ( 20, v2 ) local l = volumeBar.xScale local cnt1 = 0 local cnt2 = 0 local cnt3 = 0 local ONE =1 local val = event.numTaps --local px=event.x --local py=event.y if "ended" == phase then --audio.play( popSound ) --myLabel.isVisible = false if l > 50 and l <=150 then -- c1:setFillColor(10,105,0) -- c1.isVisible=false c1.x=math.random( 10, 450 ) c1.y=math.random( 10, 300 ) physics.addBody( c1, { density=1, radius=10.0 } ) c1.isVisible=true cnt1= cnt1+ ONE return c1 elseif l > 100 and l <=250 then --c2:setFillColor(200,10,0) c2.x=math.random( 10, 450 ) c2.y=math.random( 10, 300 ) physics.addBody( c2, { density=2, radius=9000.0 } ) c2.isVisible=true cnt2= cnt2+ ONE return c2 elseif l >=250 then c3.x=math.random( 40, 450 ) c3.y=math.random( 40, 300 ) physics.addBody( c3, { density=2, radius=7000.0 , bounce=0.0 } ) c3.isVisible=true cnt3= cnt3+ ONE return c3 end end end buzzR:addEventListener( "touch", spawnDisk ) -- touch the screen to create disks Now both functions work fine independently but there is no collision happening. Its almost as if the translating object and the spawn object are on different layers. The translating object passes through the spawn object freely. Can anyone please tell me how to resolve this problem. And how can I get them to collide. Its my first attempt at game development, that too for a mobile platform so would appreciate all help. Also if I have not been specific do let me know. I ll try to frame the query better :). Thanks in advance.

• 4.8M wasn't enough so we went for 5.055M tpmc with Unbreakable Enterprise Kernel r2 :-)

  - by wcoekaer

  We released a new set of benchmarks today. One is an updated tpc-c from a few months ago where we had just over 4.8M tpmc at $0.98 and we just updated it to go to 5.05M and $0.89. The other one is related to Java Middleware performance. You can find the press release here. Now, I don't want to talk about the actual relevance of the benchmark numbers, as I am not in the benchmark team. I want to talk about why these numbers and these efforts, unrelated to what they mean to your workload, matter to customers. The actual benchmark effort is a very big, long, expensive undertaking where many groups work together as a big virtual team. Having the virtual team be within a single company of course helps tremendously... We already start with a very big server setup with tons of storage, many disks, lots of ram, lots of cpu's, cores, threads, large database setups. Getting the whole setup going to start tuning, by itself, is no easy task, but then the real fun starts with tuning the system for optimal performance -and- stability. A benchmark is not just revving an engine at high rpm, it's actually hitting the circuit. The tests require long runs, require surviving availability tests, such as surviving crashes -and- recovery under load. In the TPC-C example, the x4800 system had 4TB ram, 160 threads (8 sockets, hyperthreaded, 10 cores/socket), tons of storage attached, tons of luns visible to the OS. flash storage, non flash storage... many things at high scale that all have to be perfectly synchronized. During this process, we find bugs, we fix bugs, we find performance issues, we fix performance issues, we find interesting potential features to investigate for the future, we start new development projects for future releases and all this goes back into the products. As more and more customers, for Oracle Linux, are running larger and larger, faster and faster, more mission critical, higher available databases..., these things are just absolutely critical. Unrelated to what anyone's specific opinion is about tpc-c or tpc-h or specjenterprise etc, there is a ton of effort that the customer benefits from. All this work makes Oracle Linux and/or Oracle Solaris better platforms. Whether it's faster, more stable, more scalable, more resilient. It helps. Another point that I always like to re-iterate around UEK and UEK2 : we have our kernel source git repository online. Complete changelog of the mainline kernel, and our changes, easy to pull, easy to dissect, easy to know what went in when, why and where. No need to go log into a website and manually click through pages to hopefully discover changes or patches. No need to untar 2 tar balls and run a diff.

• ZFS for Database Log Files

  - by user12620111

  I've been troubled by drop outs in CPU usage in my application server, characterized by the CPUs suddenly going from close to 90% CPU busy to almost completely CPU idle for a few seconds. Here is an example of a drop out as shown by a snippet of vmstat data taken while the application server is under a heavy workload. # vmstat 1  kthr      memory            page            disk          faults      cpu  r b w   swap  free  re  mf pi po fr de sr s3 s4 s5 s6   in   sy   cs us sy id  1 0 0 130160176 116381952 0 16 0 0 0 0  0  0  0  0  0 207377 117715 203884 70 21 9  12 0 0 130160160 116381936 0 25 0 0 0 0 0  0  0  0  0 200413 117162 197250 70 20 9  11 0 0 130160176 116381920 0 16 0 0 0 0 0  0  1  0  0 203150 119365 200249 72 21 7  8 0 0 130160176 116377808 0 19 0 0 0 0  0  0  0  0  0 169826 96144 165194 56 17 27  0 0 0 130160176 116377800 0 16 0 0 0 0  0  0  0  0  1 10245 9376 9164 2  1 97  0 0 0 130160176 116377792 0 16 0 0 0 0  0  0  0  0  2 15742 12401 14784 4 1 95  0 0 0 130160176 116377776 2 16 0 0 0 0  0  0  1  0  0 19972 17703 19612 6 2 92  14 0 0 130160176 116377696 0 16 0 0 0 0 0  0  0  0  0 202794 116793 199807 71 21 8  9 0 0 130160160 116373584 0 30 0 0 0 0  0  0 18  0  0 203123 117857 198825 69 20 11 This behavior occurred consistently while the application server was processing synthetic transactions: HTTP requests from JMeter running on an external machine. I explored many theories trying to explain the drop outs, including: Unexpected JMeter behavior Network contention Java Garbage Collection Application Server thread pool problems Connection pool problems Database transaction processing Database I/O contention Graphing the CPU %idle led to a breakthrough: Several of the drop outs were 30 seconds apart. With that insight, I went digging through the data again and looking for other outliers that were 30 seconds apart. In the database server statistics, I found spikes in the iostat "asvc_t" (average response time of disk transactions, in milliseconds) for the disk drive that was being used for the database log files. Here is an example:                     extended device statistics     r/s    w/s   kr/s   kw/s wait actv wsvc_t asvc_t  %w  %b device     0.0 2053.6    0.0 8234.3  0.0  0.2    0.0    0.1   0  24 c3t60080E5...F4F6d0s0     0.0 2162.2    0.0 8652.8  0.0  0.3    0.0    0.1   0  28 c3t60080E5...F4F6d0s0     0.0 1102.5    0.0 10012.8  0.0  4.5    0.0    4.1   0  69 c3t60080E5...F4F6d0s0     0.0   74.0    0.0 7920.6  0.0 10.0    0.0  135.1   0 100 c3t60080E5...F4F6d0s0     0.0  568.7    0.0 6674.0  0.0  6.4    0.0   11.2   0  90 c3t60080E5...F4F6d0s0     0.0 1358.0    0.0 5456.0  0.0  0.6    0.0    0.4   0  55 c3t60080E5...F4F6d0s0     0.0 1314.3    0.0 5285.2  0.0  0.7    0.0    0.5   0  70 c3t60080E5...F4F6d0s0 Here is a little more information about my database configuration: The database and application server were running on two different SPARC servers. Storage for the database was on a storage array connected via 8 gigabit Fibre Channel Data storage and log file were on different physical disk drives Reliable low latency I/O is provided by battery backed NVRAM Highly available: Two Fibre Channel links accessed via MPxIO Two Mirrored cache controllers The log file physical disks were mirrored in the storage device Database log files on a ZFS Filesystem with cutting-edge technologies, such as copy-on-write and end-to-end checksumming Why would I be getting service time spikes in my high-end storage? First, I wanted to verify that the database log disk service time spikes aligned with the application server CPU drop outs, and they did: At first, I guessed that the disk service time spikes might be related to flushing the write through cache on the storage device, but I was unable to validate that theory. After searching the WWW for a while, I decided to try using a separate log device: # zpool add ZFS-db-41 log c3t60080E500017D55C000015C150A9F8A7d0 The ZFS log device is configured in a similar manner as described above: two physical disks mirrored in the storage array. This change to the database storage configuration eliminated the application server CPU drop outs: Here is the zpool configuration: # zpool status ZFS-db-41   pool: ZFS-db-41  state: ONLINE  scan: none requested config:         NAME                                     STATE         ZFS-db-41                                ONLINE           c3t60080E5...F4F6d0  ONLINE         logs           c3t60080E5...F8A7d0  ONLINE Now, the I/O spikes look like this:                     extended device statistics                  r/s    w/s   kr/s   kw/s wait actv wsvc_t asvc_t  %w  %b device     0.0 1053.5    0.0 4234.1  0.0  0.8    0.0    0.7   0  75 c3t60080E5...F8A7d0s0                     extended device statistics                  r/s    w/s   kr/s   kw/s wait actv wsvc_t asvc_t  %w  %b device     0.0 1131.8    0.0 4555.3  0.0  0.8    0.0    0.7   0  76 c3t60080E5...F8A7d0s0                     extended device statistics                  r/s    w/s   kr/s   kw/s wait actv wsvc_t asvc_t  %w  %b device     0.0 1167.6    0.0 4682.2  0.0  0.7    0.0    0.6   0  74 c3t60080E5...F8A7d0s0     0.0  162.2    0.0 19153.9  0.0  0.7    0.0    4.2   0  12 c3t60080E5...F4F6d0s0                     extended device statistics                  r/s    w/s   kr/s   kw/s wait actv wsvc_t asvc_t  %w  %b device     0.0 1247.2    0.0 4992.6  0.0  0.7    0.0    0.6   0  71 c3t60080E5...F8A7d0s0     0.0   41.0    0.0   70.0  0.0  0.1    0.0    1.6   0   2 c3t60080E5...F4F6d0s0                     extended device statistics                  r/s    w/s   kr/s   kw/s wait actv wsvc_t asvc_t  %w  %b device     0.0 1241.3    0.0 4989.3  0.0  0.8    0.0    0.6   0  75 c3t60080E5...F8A7d0s0                     extended device statistics                  r/s    w/s   kr/s   kw/s wait actv wsvc_t asvc_t  %w  %b device     0.0 1193.2    0.0 4772.9  0.0  0.7    0.0    0.6   0  71 c3t60080E5...F8A7d0s0 We can see the steady flow of 4k writes to the ZIL device from O_SYNC database log file writes. The spikes are from flushing the transaction group. Like almost all problems that I run into, once I thoroughly understand the problem, I find that other people have documented similar experiences. Thanks to all of you who have documented alternative approaches. Saved for another day: now that the problem is obvious, I should try "zfs:zfs_immediate_write_sz" as recommended in the ZFS Evil Tuning Guide.

• Can't install alternate CD from USB?

  - by mattias

  Hi im trying to install ubuntu 12.04 with full hard disk encryption. After downloading and installing the Ubuntu live CD, I learned that truecrypt doesnt support full disk encryption on linux. I also learned that the best way to get "nearly full disk encryption" on ubuntu is by installing it from the alternate install CD. I tried that, but something is wrong with my CD reader/burner so it doesnt boot up when i insert the cd. My thought here was to take the .iso that I downloaded on my unencrypted Ubuntu system, use Unetbootin to make the usb drive. The usb drive used for this is exactly the same brand as one that I know has worked with a previous ubuntu live system on the same computer. I also used unetbootin for that usb, but I created it from windows that time. The usb stick boots up fine and i get through the first couple of steps in the installation process. However, After a while I get a "box" with the following error message "Load Installer components from CD" There was a problem reading data from the CD-ROM. Please make sure it is in the drive. If retrying does not work, you should check the integrity of your CD-ROM. "Failed to copy file from CD-ROM. Retry? " Then I cant get any further. I googled a lot and found this page which seems to tackle this very problem: http://www.dotkam.com/2010/11/29/ins...mage-from-usb/ I tried to do what it said. After pressing TAB, I wrote : cdrom-detect/try-usb=true without quotes because that's what i think is right. When I press TAB, there already is a text saying : /ubnkern initrd=/ubninit vga=788 -- quiet which can be removed. I have tried to both delete the text before the "--" and just inserting cdrom-detect/try-usb=true before it. Any idea of what can be wrong? I would like to do a full system encryption, or as full as it is possible. I dont want to just encrypt my /home folder. Maybe this isn't the easiest way. I use SanDisk usb sticks. I know there is a problem with U3 launcher on some SanDisks, but I never had to remove U3 before from similar disks, and the alternate install does boot up, so I dont think using U3 removal would help me. Any help or indication to an easier way to do this would be appreciated

• Complex event system for DungeonKeeper like game

  - by paul424

  I am working on opensource GPL3 game. http://opendungeons.sourceforge.net/ , new coders would be welcome. Now there's design question regarding Event System: We want to improve the game logic, that is program a new event system. I will just repost what's settled up already on http://forum.freegamedev.net/viewtopic.php?f=45&t=3033. From the discussion came the idea of the Publisher / Subscriber pattern + "domains": My current idea is to use the subscirbers / publishers model. Its similar to Observable pattern, but instead one subscribes to Events types, not Object's Events. For each Event would like to have both static and dynamic type. Static that is its's type would be resolved by belonging to the proper inherited class from Event. That is from Event we would have EventTile, EventCreature, EvenMapLoader, EventGameMap etc. From that there are of course subtypes like EventCreature would be EventKobold, EventKnight, EventTentacle etc. The listeners would collect the event from publishers, and send them subcribers , each of them would be a global singleton. The Listeners type hierachy would exactly mirror the type hierarchy of Events. In each constructor of Event type, the created instance would notify the proper listeners. That is when calling EventKnight the proper ctor would notify the Listeners : EventListener, CreatureLisener and KnightListener. The default action for an listner would be to notify all subscribers, but there would be some exceptions , like EventAttack would notify AttackListener which would dispatch event by the dynamic part ( that is the Creature pointer or hash). Any comments ? #include <vector> class Subscriber; class SubscriberAttack; class Event{ private: int foo; int bar; protected: // static std::vector<Publisher*> publishersList; static std::vector<Subscriber*> subscribersList; static std::vector<Event*> eventQueue; public: Event(){ eventQueue.push_back(this); } static int subscribe(Subscriber* ss); static int unsubscribe(Subscriber* ss); //static int reg_publisher(Publisher* pp); //static int unreg_publisher(Publisher* pp); }; // class Publisher{ // }; class Subscriber{ public: int (*newEvent) (Event* ee); Subscriber( ){ Event::subscribe(this); } Subscriber( int (*fp) (Event* ee) ):newEvent(fp){ Subscriber(); } ~Subscriber(){ Event::unsubscribe(this); } }; class EventAttack: Event{ private: int foo; int bar; protected: // static std::vector<Publisher*> publishersList; static std::vector<SubscriberAttack*> subscribersList; static std::vector<EventAttack*> eventQueue; public: EventAttack(){ eventQueue.push_back(this); } static int subscribe(SubscriberAttack* ss); static int unsubscribe(SubscriberAttack* ss); //static int reg_publisher(Publisher* pp); //static int unreg_publisher(Publisher* pp); }; class AttackSubscriber :Subscriber{ public: int (*newEvent) (EventAttack* ee); AttackSubscriber( ){ EventAttack::subscribe(this); } AttackSubscriber( int (*fp) (EventAttack* ee) ):newEventAttack(fp){ AttackSubscriber(); } ~AttackSubscriber(){ EventAttack::unsubscribe(this); } }; From that point, others wanted the Subject-Observer pattern, that is one would subscribe to all event types produced by particular object. That way it came out to add the domain system : Huh, to meet the ability to listen to particular game's object events, I though of introducing entity domains . Domains are trees, which nodes are labeled by unique names for each level. ( like the www addresses ). Each Entity wanting to participate in our event system ( that is be able to publish / produce events ) should at least now its domain name. That would end up in Player1/Room/Treasury/#24 or Player1/Creature/Kobold/#3 producing events. The subscriber picks some part of a tree. For example by specifiing subtree with the root in one of the nodes like Player1/Room/* ,would subscribe us to all Players1's room's event, and Player1/Creature/Kobold/#3 would subscribe to Players' third kobold's event. Does such event system make sense to you ? I have many implementation details to ask as well, but first let's start some general discussion. Note1: Notice that in the case of a fight between two creatues fight , the creature being attacked would have to throw an event, becuase it is HE/SHE/IT who have its domain address. So that would be BeingAttackedEvent() etc. I will edit that post if some other reflections on this would come out. Note2: the existing class hierarchy might be used to get the domains addresses being build in constructor . In a ctor you would just add + ."className" to domain address. If you are in a class'es hierarchy leaf constructor one might use nextID , hash or any other charactteristic, just to make the addresses distinguishable . Note3:subscribing to all entity's Events would require knowledge of all possible events produced by this entity . This could be done in one function call, but information on E produced would have to be handled for every Entity. SmartNote4 : Finding proper subscribers in a tree would be easy. One would start in particular Leaf for example Player1/Creature/Kobold/#3 and go up one parent a time , notifiying each Subscriber in a Node ie. : Player1/Creature/Kobold/* , Player1/Creature/* , Player1/* etc, , up to a root that is /* .<<<< Note5: The Event system was needed to have some way of incorporating Angelscript code into application. So the Event dispatcher was to be a gate to A-script functions. But it came out to this one.

• What does "single-bit ECC errors were detected on the RAID controller" mean?

  - by jsp

  I have a Dell T7600 with a Perc H710P RAID controller and 4 attached 3TB drives. Over the past few months the RAID controller has been intermittently reporting errors on boot: "no boot device found", "adapter at baseport is not responding", disks frequently reported as missing or failed. I have since replaced the RAID controller, the 4 hard drives, and finally the system's motherboard. After replacing the motherboard and rebooting a few times, I got the error Single bit ECC errors were detected on the RAID controller. Please contact technical support to resolve this issue. After rebooting about 20 more times, I haven't seen the ECC error. The system seems otherwise OK, except for the fact that the disk fans will sometimes start blowing at full blast when the the system is sitting completely idle and not stop until I reboot. Are the ECC errors in memory on the RAID controller? Or, does the RAID controller map in system memory, and the ECC errors are really in system memory? Or, are the ECC errors in the 1GB cache that resides in the RAID controller?

• Dell VRTX - slow cluster shared storage

  - by NorbyTheGeek

  I have a brand new Dell VRTX box set up as a Failover Cluster running HA Hyper-V virtual machines. This is my first time setting up clustering, and my first time with one of these boxes, so I'm sure I've missed something. The virtual machines are experiencing high disk latency and bad performance when accessing their VHD(x) files located on a Cluster Shared Volume. The VRTX has 10 x 900 GB 10K SAS drives in RAID 6 configuration, and the VRTX has the redundant Shared PERC 8 controllers. Both blades have full access to the virtual disks. There are two M520 blades installed, each with 128 GB RAM. MPIO is configured for the PERC 8 controllers. Operating system on the blades is Server 2012 (NOT R2). The RAID 6 array is split into a small (8 GB) volume for cluster quorum witness and a large (6.5 TB) volume for a Cluster Shared Volume (mounted on the nodes as C:\ClusterStorage\Volume1) An example of slow disk access: logging into a Server 2012 VM and having Server Manager come up automatically. Disk access goes to 100%, with write speeds at 20 MB or so, read speeds of 500 KB or so, and Average Response Time of over 1000 ms, sometimes spiking at 4000-5000 ms or so. It's the latency that really worries me. Is there something specific I should look at in my configuration? It doesn't seem to matter whether I use VHD or VHDX, dynamic or static.

• HYPER-V R2 Can not mount ISO from network location (UNC Path)

  - by Entity_Razer

  So, as the name suggest I'm trying to mount a ISO from a network share using the UNC path to a HYPER-V R2 Cluster. This is a pure Demo / test case setup with: 2x HYPER-V R2 1X NAS/iSCSI CSV Cluster Management is happening through the MMC with RSAT tools. So what i've done so far is: Set up the cluster and configure Quorum, add CSV Shares and disks, set up 1 Virtual Machine on the Hyper-1 node. What i'm trying to do is, you go to settings --- DVD Drive --- use network location ---- Pick ISO file and press "apply". Error I'm getting is either "User account does not have rights to mount iso". I changed that or stopped getting that message when I went to the HYPER-V Node settings and tabbed on: "Use Default Credentials Automatically". Now I stopped getting the "user does not have right..." message but I get the following: Error applying DVD Drive Changes Failed to remove device microsoft synthetic DVD Drive:" the specified network resource or device is no longer available" I've google'd the problem but am unable to find a solution. Anyone here able to help me out ? Much abbliged !

• How to disable the RAID in x3400 M2

  - by BanKtsu

  Hi I just wanna disable the default RAID in my server IBM System X3400 M2 Server(7837-24X),i have 3 disk drives SAS. I want to make them a JBOD "Just a Bunch Of Disks", because I want to install in the drive 0 CentOS, and the other two make them cache files for a squid server. I disable the RAID in the BIOS: System Settings/Adapters and UEFI drivers/LSI Logic Fusion MPT SAS Driver -PciRoot(0x0)/Pci(0x3,0X0)/Pci(0x0,0x0) LSI Logic MPT Setup Utility RAID Properties/Delete Array Later I boot the CentOS live CD and install the OS in the drive 0, and the others 2 mounted like this: *LVM Volume Groups vg_proxyserver 139508 lv_root 51200 / ext4 lv_home 84276 /home ext4 lv_swap 4032 Hard Drive sdb(/dev/sdb) free 140011 sdc(/dev/sdc) free 140011 sdd(/dev/sdd) sdd1 500 /boot ext4 sdd2 139512 vg_proxyserver physical volume(LVM) But when I restart the server give me the error: Boot failed Hard Disk 0 UEFI PXE PciRoot(0x0)/Pci(0x1,0X0)/Pci(0x0,0x0)/MAC(001A64B15130,0X0)) ........PXE-E18:Server response timeout.

• i5 540M or i7 720QM for laptop running VMs and software development tools?

  - by Donald Hughes

  I'm a software developer that would primarily be running Windows 7 as the primary operating system. On a typical day, I might, at any given moment, be running Visual Studio, Expression Web, SQL Server developer (and Management Console), IIS, Photoshop, a dozen browser tabs in 2-3 different browsers, Skype video chat, streaming music, and a couple of VMs (WinXP and Ubuntu) for testing/experimentation. Obviously, RAM is a concern, which is why I plan to use 8 GB so I can devote enough to the VMs to be usable. I'm also tempted to use an ExpressCard SSD for storing the VM disks to ease disk contention. And I know that that is asking a lot from a laptop, and I should just use a desktop, but I need to be able to take my work with me between several locations. It seems that at a reasonable price point, it comes down to the i5 540M versus the i7 720QM. I'm leaning toward the i7 since it would allow me to dedicate a whole hyperthreaded core to each VM, and still have two cores left for the primary OS. I've heard that the i5 has better battery life, but I'm curious for my scenario if there would be a meaningful difference. I don't usually work without a plug, but I do occasionally ride the train or fly and it would be nice to have at least 3 hours of juice for unusual circumstances. And, finally, for this usage scenario, would a dedicated video option be preferred over the i5's integrated video? It sounds like Visual Studio 2010 (and Windows 7) can take advantage of the video card.

• Jquery datepicker popup not closing on select date in IE8

  - by Notorious2tall

  I've got a web form with a start date field. I've tied a jquery datepicker to the txt field. Now when I choose a date in FF, the selected date is populated in the text box and the calendar popup closes. However when I do the same thing in IE8, the selected date is populated in the text box but the popup remains open. I've also noticed that a script error is generated as soon as I select a date in the popup calendar. I'm using jquery 1.3.2, jquery-ui 1.7.2, and .NET 3.5. Here's an example of my code: <script type="text/javascript"> $(document).ready(function() { $("#<%=txtStartDate.ClientID%>").datepicker({ changeMonth: true, changeYear: true, showButtonPanel: true, showOn: 'button', buttonImage: '/_layouts/images/CALENDAR.GIF', buttonImageOnly: true }); }); </script> <div id="stylized"> <asp:ValidationSummary ID="vs" runat="server" CssClass="messages-error" HeaderText=" Action required before the form can be submitted." ForeColor="" ValidationGroup="sh" /> <div class="formrow"> <div class="ms-formlabel formlabel"> <asp:Label ID="lblStartDate" runat="server" CssClass="ms-standardheader" AssociatedControlID="txtStartDate">Start Date:</asp:Label> </div> <div class="ms-formbody formfield"> <asp:RequiredFieldValidator ID="reqStartDate" runat="server" ControlToValidate="txtStartDate" ErrorMessage="Start Date is a required field." Text="*" Display="Dynamic" ValidationGroup="sh"></asp:RequiredFieldValidator> <asp:CompareValidator ID="cvStartDate" runat="server" ControlToValidate="txtStartDate" ErrorMessage="Date must be in the format MM/DD/YYYY" Text="*" Display="Dynamic" ValidationGroup="sh" Operator="DataTypeCheck" Type="Date"></asp:CompareValidator> <asp:TextBox ID="txtStartDate" runat="server"></asp:TextBox> <span class="formMessage">ex. MM/DD/YYYY</span> </div> </div> <div id="buttonrow"> <asp:Button ID="btnSubmit" runat="server" Text="Submit" CssClass="ms-ButtonHeightWidth" OnClick="Submit_Click" ValidationGroup="sh" /> <asp:Button ID="btnCancel" runat="server" Text="Cancel" CssClass="ms-ButtonHeightWidth" OnClick="Cancel_Click" CausesValidation="false" /> </div> </div> Here's the script error I get in IE when I select the date: 'length' is null or not an object WebResource.axd Here's the code where the error is being thrown from: function ValidatorOnChange(event) { if (!event) { event = window.event; } Page_InvalidControlToBeFocused = null; var targetedControl; if ((typeof(event.srcElement) != "undefined") && (event.srcElement != null)) { targetedControl = event.srcElement; } else { targetedControl = event.target; } var vals; if (typeof(targetedControl.Validators) != "undefined") { vals = targetedControl.Validators; } else { if (targetedControl.tagName.toLowerCase() == "label") { targetedControl = document.getElementById(targetedControl.htmlFor); vals = targetedControl.Validators; } } var i; for (i = 0; i < vals.length; i++) { ValidatorValidate(vals[i], null, event); } ValidatorUpdateIsValid(); } It happens on the .length in the for loop at the end. Vals is null and isn't found in the previous if/else. I've stepped through the javascript and if (typeof(targetedControl.Validators) != "undefined") returns false and then if (targetedControl.tagName.toLowerCase() == "label") returns false too. Thus the length is null or not an object error. Now I'm not sure if the datepicker popup not closing in IE and the script error in the WebResources.axd file are related errors, but I'm leaning that way. Can anyone tell me why the popup isn't closing?

• Recommendation for Ethernet switches that allow arbitrary network topologies

  - by sblair

  We have the following requirements for three Ethernet switches that will be connected together: Allow the switches to connect together to form dynamic, arbitrary topologies, i.e., support for the RSTP is essential. Allow the physical topology (which ports are connected together) to be gleaned from the switches, e.g., using SNMP traps. This is optional, but would be very useful. At least 5 ports on each switch, but only 3 will be used for connecting the switches together. Be as compact as possible. Ideally be in stock, in the UK. Only 100Mb/s is required. (This question is the result of the lack of RSTP support from 3Com NJ225 devices, as described in my previous question.)

• Drop outs when accessing share by DFS name.

  - by Stephen Woolhead

  I have a strange problem, aren't they all! I have a DFS root \domain\files\vms, it has a single target on a different server than the namespace. I can copy a test file set from the target directly via \server\vms$\testfiles and all is well, the files copy fine. I have repeated these tests many times. If I try and copy the files from the dfs root I get big pauses in the network traffic, about 50 seconds every couple of minutes, all the traffic just stops for the copy. If I start another copy between the same two machines during this pause, it starts copying fine, so I know it's not an issue with the disks on the server. Every once in a while the copy will fail, no errors, the progress bar will just zip all the way to 100% and the copy dialog will close. Checking the target folder show that the copy is incomplete. I've moved the LUN to another server and had the same problem. The servers are all 2008 R2, the clients are Vista x64, Windows7 x64 and 2008 R2, all have the same problem. Anyone got any ideas? Cheers, Stephen More Information: I've been running a NetMon trace on the connection when the file copy fails and what seems to be standing out is that when opening a file that the copy completes on the SMB command looks like this: SMB2: C CREATE (0x5), Name=Training\PDC2008\BB34 Live Services Notifications, Awareness, and Communications.wmv@#422082, Context=DHnQ, Context=MxAc, Context=QFid, Context=RqLs, Mid = 245376 SMB2: R CREATE (0x5), Context=MxAc, Context=RqLs, Context=DHnQ, Context=QFid, FID=0xFFFFFFFF00000015, Mid = 245376 But for the last file when the copy dialog closes looks like this: SMB2: C CREATE (0x5), Name=gt\files\Media\Training\PDC2008\BB36 FAST Building Search-Driven Portals with Microsoft Office SharePoint Server 2007 and Microsoft Silverlight.wmv@#859374, Context=DHnQ, Context=MxAc, Context=QFid, Context=RqLs, Mid = 77 SMB2: R , Mid = 77 - NT Status: System - Error, Code = (58) STATUS_OBJECT_PATH_NOT_FOUND The main difference seems to be in the name, one is relative to the open file share, the other has gained the gt\files\media prefix which is the name of the DFS target. These failures are always preceded by logoff and back on of the SMB target. Might have to bump this one to PSS.

• SUSE 12.1 Apache startup after oci8 installation

  - by DKSan

  I have got a virtual server running opensuse 11.4 with apache, php, oracle instantclient, and oci installed through pecl. The steps it took for me to have it up and running on 11.4 were: # Install instantclient rpm -Uvh oracle-instantclient11.2-basic-11.2.0.2.0.x86_64.rpm rpm -Uvh oracle-instantclient11.2-devel-11.2.0.2.0.x86_64.rpm # Install OCI8 through pecl pecl install oci8 # add oci8 to modules vi /etc/php5/conf.d/oci8.ini extension=oci8.so # add LD_LIBRARY_PATH to apache vi /etc/sysconfig/apache2 # add to bottom of script export LD_LIBRARY_PATH="/usr/lib/oracle/11.2/client64/lib" # restart Apache /etc/init.d/apache2 restart Celebrating the same procedure on a fresh installation of OpenSUSE 12.1 results in apache throwing the following message at startup: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64/php5/extensions/oci8.so' - libnnz11.so: cannot open shared object file: No such file or directory in Unknown on line 0 I can't get any explanation, why it is working for 11.4 and in 12.1 it stops working. Can someone please point me in the right direction..

• Marrying Core Animation with OpenGL ES

  - by Ole Begemann

  Edit: I suppose instead of the long explanation below I might also ask: Sending -setNeedsDisplay to an instance of CAEAGLLayer does not cause the layer to redraw (i.e., -drawInContext: is not called). Instead, I get this console message: <GLLayer: 0x4d500b0>: calling -display has no effect. Is there a way around this issue? Can I invoke -drawInContext: when -setNeedsDisplay is called? Long explanation below: I have an OpenGL scene that I would like to animate using Core Animation animations. Following the standard approach to animate custom properties in a CALayer, I created a subclass of CAEAGLLayer and defined a property sceneCenterPoint in it whose value should be animated. My layer also holds a reference to the OpenGL renderer: #import <UIKit/UIKit.h> #import <QuartzCore/QuartzCore.h> #import "ES2Renderer.h" @interface GLLayer : CAEAGLLayer { ES2Renderer *renderer; } @property (nonatomic, retain) ES2Renderer *renderer; @property (nonatomic, assign) CGPoint sceneCenterPoint; I then declare the property @dynamic to let CA create the accessors, override +needsDisplayForKey: and implement -drawInContext: to pass the current value of the sceneCenterPoint property to the renderer and ask it to render the scene: #import "GLLayer.h" @implementation GLLayer @synthesize renderer; @dynamic sceneCenterPoint; + (BOOL) needsDisplayForKey:(NSString *)key { if ([key isEqualToString:@"sceneCenterPoint"]) { return YES; } else { return [super needsDisplayForKey:key]; } } - (void) drawInContext:(CGContextRef)ctx { self.renderer.centerPoint = self.sceneCenterPoint; [self.renderer render]; } ... (If you have access to the WWDC 2009 session videos, you can review this technique in session 303 ("Animated Drawing")). Now, when I create an explicit animation for the layer on the keyPath @"sceneCenterPoint", Core Animation should calculate the interpolated values for the custom properties and call -drawInContext: for each step of the animation: - (IBAction)animateButtonTapped:(id)sender { CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"sceneCenterPoint"]; animation.duration = 1.0; animation.fromValue = [NSValue valueWithCGPoint:CGPointZero]; animation.toValue = [NSValue valueWithCGPoint:CGPointMake(1.0f, 1.0f)]; [self.glView.layer addAnimation:animation forKey:nil]; } At least that is what would happen for a normal CALayer subclass. When I subclass CAEAGLLayer, I get this output on the console for each step of the animation: 2010-12-21 13:59:22.180 CoreAnimationOpenGL[7496:207] <GLLayer: 0x4e0be20>: calling -display has no effect. 2010-12-21 13:59:22.198 CoreAnimationOpenGL[7496:207] <GLLayer: 0x4e0be20>: calling -display has no effect. 2010-12-21 13:59:22.216 CoreAnimationOpenGL[7496:207] <GLLayer: 0x4e0be20>: calling -display has no effect. 2010-12-21 13:59:22.233 CoreAnimationOpenGL[7496:207] <GLLayer: 0x4e0be20>: calling -display has no effect. ... So it seems that, possibly for performance reasons, for OpenGL layers, -drawInContext: is not getting called because these layers do not use the standard -display method to draw themselves. Can anybody confirm that? Is there a way around it? Or can I not use the technique I laid out above? This would mean I would have to implement the animations manually in the OpenGL renderer (which is possible but not as elegant IMO).

• No VMKernel Dump File on PSOD for ESXi 4

  - by user66481

  On PSOD no VMKernel Dump File is written to disk and no message is written to screen (the screen is either blank or full of dashes). I need this data to understand why the system crashes; any help as to how to fix this to write a dump file would be appreciated. Thanks. Notes: VMKCore partition exists, is active, and is configured (esxcfg-dumppart -l). esxcfg-advcfg -g /Misc/PsodOnCosPanic = 1. esxcfg-advcfg -g /Misc/CosCoreFile = /var/core. esxcfg-dumppart -C -D /vmfs/devices/disks/ = "Error running command. Unable to copy the dump partition: Couldn't find a valid VMKernel dump file. Dump partition might be uninitialized." Hardware diagnostics (Dell) checks okay.

• How to install Windows 7 onto software RAID-0

  - by Jay B

  I recently got a new laptop (Asus G73JH-A2) which has two identical hard drives in it. Unfortunately the motherboard does not have a RAID controller. What I would like to do is run the drives in a RAID-0 configuration to improve performance (plus get the extra capacity on one partition). I would like Windows installed onto the striped volume (RAID 0). I have spent some time using diskpart to create a striped volume across the two drives, however when I go to install windows and select the volume it will not let me select 'Next' giving the error "Windows cannot be installed to this hard disk space. The partition contains one or more dynamic volumes that are not supported for installation." I'm hoping theres a step that I am missing that will allow me to install windows on a striped volume. Any ideas?

• Filesystems for webserver with SATA and Solid State disk,

  - by Jorisslob

  We have just ordered a new webserver with 120 Gb solid state disk and a SATA disk. I am trying to plan ahead what sort of filesystem to use. This system will be running Linux, Apache/Tomcat to host java services. The main service is a system where people can upload reasonably large files (in the order of 100 Mb, images, image stacks and video), which people will be able to annotate and which will be sent to a database server when annotation is complete. Thus far, I plan to put most of the utility programs of the operating system om the SSD and put the large media files there. The SATA disks will hold the less volitile data like apache, tomcat and the servlets. For filesystems I have considered going for the stable EXT3 because I hear that it is best supported. The downside seems to be that it not the ideal choice for large files. That is why I am leaning towards using XFS for the SSD and EXT3 for the SATA. My questions are: 1) Does this sound like a reasonable setup? 2) What filesystems would you recommend for the SSD and for the SATA? Thanks

• "Could not claim interface on camera: -6" when trying to connect usb camera (Kinect)

  - by rzetterberg

  I have installed the freenect library from openkinect.org. With that library there is a demo application which you can run from the terminal to test out the Kinect. However when I run this command I get the following output: richard@behemoth:~$ sudo freenect-glview Kinect camera test Number of devices found: 1 Could not claim interface on camera: -6 Could not open device This particular error is thrown by the library libusb by the function libusb_claim_interface and the error -6 corresponds to the LIBUSB_ERROR_BUSY. So my guess is that it has something to do with mounting the usb, rather than specifically the freenect library or the Kinect itself. So my question is how can I find out what resource is using this interface and how can I free it so that I can access it? Edit: What I have tried so far (just to be sure): Rebooted Plugged-out, plugged-in Tried different usb ports Restarted udev Additional information that might be useful: /etc/fstab: # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed.
