While some companies can use their production OLTP system for running operational reports, for many it is too much overhead and performance impact for transaction processing systems.  Oracle GoldenGate’s real-time data integration capabilities enable companies to create a real-time replica of their OLTP systems, dedicated for operational reporting. This instance can be optimized for the reports needed as well such as containing only the tables needed from the source. Oracle GoldenGate has certified solutions for many Oracle applications such as EBusiness Suite, Peoplesoft, JD Edwards, to offload operational reporting to another reporting server that has real-time data feeding from the production system. At Oracle OpenWorld we will be hearing from a panel of Oracle GoldenGate customers how they deployed GoldenGate for operational reporting. Comcast, Turk Telekom, and Raymond James will be sharing their experiences and the benefits achieved when implementing GoldenGate’s solution. If you have performance degradation in your production systems due to reporting or ad-hoc queries, and you will be at OpenWorld, don’t miss this informative session: Real-World Operational Reporting with Oracle GoldenGate: Customer Panel-- Tuesday Oct 2nd 11:45am Mascone West 3005.

  • Upcoming Carbon Tax in South Africa

    - by Evelyn Neumayr
    By Elena Avesani, Principal Product Strategy Manager, Oracle In 2012, the South Africa National Treasury announced the plan to impose a carbon tax to cut carbon emissions that are blamed for climate change. South Africa is ranked among the top 20 countries measured by absolute carbon dioxide emissions, with emissions per capita in the region of 10 metric tons per annum and over 90% of South Africa's energy produced by burning fossil fuels. The top 40 largest companies in the country are responsible for 207 million tons of carbon dioxide, directly emitting 20 percent of South Africa’s carbon output. The legislation, originally scheduled to be implemented from January 2015 to 31 December 2019, is now delayed to January 2016. It will levy a carbon tax of R120 (US$11) per ton of CO2, rising then by 10 percent a year until 2020, while all sectors bar electricity will be able to claim additional relief of at least 10 percent. The South African treasury proposed a 60 percent tax-free threshold on emissions for all sectors, including electricity, petroleum, iron, steel and aluminum. Oracle Environmental Accounting and Reporting (EA&R) supports these needs and guarantees consistency across organizations in how data is collected, retained, controlled, consolidated and used in calculating and reporting emissions inventory. EA&R also enables companies to develop an enterprise-wide data view that includes all 5 of the key sustainability categories: carbon emissions, energy, water, materials and waste. Thanks to its native integration with Oracle E-Business Suite and JD Edwards EnterpriseOne ERP Financials and Inventory Systems and the capability of capturing environmental data across business silos, Oracle Environmental Accounting and Reporting is uniquely positioned to support a strategic approach to carbon management that drives business value.

  • CFOs: Do You Have a Playbook for Growth?

    - by Oracle Accelerate for Midsize Companies
    by Jim Lein, Oracle Midsize Programs In most global markets, CFOs are optimistic about their company's growth opportunities. Deloitte's CFO Signals Report, "Time to Accelerate" found that: In the U.K. business optimism is at its highest level in three-and-a-half years Optimism in North America rose from a strong +42% last quarter (Q2 to Q3 2013) to an even stronger +54%.

  • Exclude debug javascript code during minification

    - by Tauren
    I looking into different ways to minify my javascript code including the regular JSMin, Packer, and YUI solutions. I'm really interested in the new Google Closure Compiler, as it looks exceptionally powerful. I noticed that Dean Edwards packer has a feature to exclude lines of code that start with three semicolons. This is handy to exclude debug code. For instance: ;;; console.log("Starting process"); I'm spending some time cleaning up my codebase and would like to add hints like this to easily exclude debug code. In preparation for this, I'd like to figure out if this is the best solution, or if there are other techniques. Because I haven't chosen how to minify yet, I'd like to clean the code in a way that is compatible with whatever minifier I end up going with. So my questions are these: Is using the semicolons a standard technique, or are there other ways to do it? Is Packer the only solution that provides this feature? Can the other solutions be adapted to work this way as well, or do they have alternative ways of accomplishing this? I will probably start using Closure Compiler eventually. Is there anything I should do now that would prepare for it?

  • WCF Mono - BasicHttpBinding with SSL

    - by TheNextman
    I'm trying to port an existing WCF client application to run on Linux under Mono. Right now I'm testing everything out, figuring out what works on Mono and what doesn't. The client makes a super simple call over basicHttpBinding. It works great, until I enable SSL (that is, specify BasicHttpSecurityMode.Transport in the binding). Running on .NET in Windows, it works great Running on Mono on Ubuntu 9.10 / Mono 2.6 I get the following error: Exception in async operation: System.Net.WebException: Error getting response stream (Write: The authentication or decryption has failed.): SendFailure --- System.IO.IOException: The authentication or decryption has failed. --- Mono.Security.Protocol.Tls.TlsException: Invalid certificate received from server. Error code: 0xffffffff800b010a I've read the Mono security FAQ here: http://www.mono-project.com/FAQ:_Security; however the SSL certificate on the server is from a root CA (a purchased certificate) - issued by Equifax Secure Certificate Authority. I ran the TlsTest tool on the Ubuntu install against the .svc URL and there are no problems/errors. Also I can hit the service fine in Firefox (no security warnings). What am I missing? Thanks in advance, Richard

  • Linq - how does it work??

    - by clarkeyboy
    Hey, I have just been looking into Linq with ASP.Net. It is very neat indeed. I was just wondering - how do all the classes get populated? I mean in ASP.Net, suppose you have a Linq file called Catalogue, and you then use a For loop to loop through Catalogue.Products and print each Product name. How do the details get stored? Does it just go through the Products table on page load and create another instance of class Product for each row, effectively copying an entire table into an array of class Product? If so, I think I have created a system very much like this, in the sense that there is a SiteContent module with an instance of each Manager class - for example there is UserManager, ProductManager, SettingManager and alike. UserManager contains an instance of the User class for each row in the Users table. They also contain methods such as Create, Update and Remove. These Managers and their "Items" are created on every page load. This just makes it nice and easy to access users, products, settings etc in every page as far as I, the developer, am concerned. Any any subsequent pages I need to create, I just need to reference SiteContent.UserManager to access a list of users, rather than executing a query from within that page (ie this method separates out data access from the workings of the page, in the same way as using code behind separates out the workings of the page from how the page is layed out). However the problem is that this technique seems rather slow. I mean it is effectively creating a database on every page load, taking data from another database. I have taken measures such as preventing, for example, the ProductManager from being created if it is not referenced on page load. Therefore it does not load data into storage when it is not needed. My question is basically whether my technique does the exact same thing as Linq, in the sense of duplicating data from tables into properties of classes.. Thanks in advance for any advice or answers about this. Regards, Richard Clarke

  • Internet Explorer 7 Bugs - incorrect display OR dead links

    - by ClarkeyBoy
    Hi, I recently launched a website I have been developing over the past year - http://Live.heritageartpapers.co.uk/. My dad, who owns the company, had a phone call today saying it doesnt display properly in IE7. Bug #1: The header and footer are both in a div, whereas the content is in a table between the two divs. Reportedly the content (table) sometimes (not always, according to IETester) displays below the footer, but the footer still displays where it is supposed to (ie there is a massive gap where the content should fit). Bug #2: When the content does display in the correct place, all the links on the page are dead - click on them and nothing happens. As you can see if you view it in Firefox (the version I am using is 3.6), the links in the left hand menu turn orange on mouseover. However they do not even do this in IE7. Note that they do turn orange and do work if the content is displayed below the footer. I cant see why its happening - according to IETester, the IE7 interpreted source code has all the tags capitalised and many quotes removed (for example for the id attribute on most, if not all, tags) but I doubt this could cause the above bugs, could it? My question is whether anyone has ever seen any of these problems before, and/or has a solution to any of these problems?? I currently do not have the application open, but will post any relevant code in a few minutes. Alternatively just use view source. Many thanks in advance. Regards, Richard Clarke

  • Postback event not firing on FIRST button click..

    - by ClarkeyBoy
    Hi, I have a form which accepts two arguments. The first one is mode - this is either view, new or edit. If it is new then the second argument is type - this is either range, collection or design. When set to new, and the type is valid, a new instance of that type is created and the data from the form is added to it. The item (range, collection or design) then validates the data. If any of the data is invalid then it throws an error, and this error is displayed at the top of the form telling the user why it is invalid. A variable, _Databind, is set to false so that it does not change the data input by the user (in the form fields). The button used to submit the button is called btnSave, and is created in the html source. The click event is wired up in the form Protected Sub Blah(sender, e) Handles btnSave.Click. Strangely, whenever I edit an item that already exists the form submits fine the first time - the click event is fired. However when in "new" mode I have to click the button twice to fire the event. It also blanks all the form fields out on first click. I have even put a Response.Write("Hello World") line at the start of the click event - this is not being output on first click when adding a new item either. It is on first load when the mode is set to edit however. Does anyone have any ideas as to what is causing it to behave this way? Thanks in advance for any help. Regards, Richard

  • ASP.Net application timeout

    - by ClarkeyBoy
    Hi, I have an application I have just deployed which, for complicated reasons, stores all the data from the database in a module the first time any data from the specific table is required (i.e. when a customer requests to view a product for the first time, all the product data is stored in the ProductManager class (of which an instance is stored in a shared property of the SiteContent class, making the ProductManager easily accessible from any page). Now forget that you are probably now glaring at me for using this approach.. I am sure it has its inefficiencies but I have only been studying .Net for a year or so now so I am still learning. One thing I have noticed is that I can go on the site once, then revisit it 5 minutes later and it will load all the data into the ProductManager class again. It seems this is a .Net application timeout thing - since the session timeout is set to 30 minutes and, when I am logged in on the administration frontend, it logs me out after 5 minutes (ish). Does anyone have any idea how to change this? Is there any way I can change this in the code without having to contact the hosting company? If not in the code is there any way to change this in the web.config? Thanks in advance. Regards, Richard

  • CSS - Class hierarchies???

    - by ClarkeyBoy
    Hi, I have a site with a customer front end, which has a catalogue, homepage, contact page, about us page and so on. There is also an administration front end. I would like to implement a kind of hierarchy where any elements within an element with class "admin" will inherit properties set in the admin stylesheet and anything else inherits from the customer stylesheet. The purpose of this is so that admin can login on the admin front end, where they have access to lots of advanced stuff, but they can also navigate to the customer front end where they can execute basic tasks (such as hiding catalogue items, running a debug script if a customer reports an issue and so on). I would like all the admin tools on the customer front end to have properties taken from the admin stylesheet instead of the customer one - this will change the background colour and stuff. Is there any easy way to set up like namespaces to make things simpler, for example: .admin { .list { .list-subtitle { } .list-item { } } a { } } .customer { .list { .list-subtitle { } .list-item { } } a { } } I know it can be like: .admin .list {} .admin .list .list-item {} .admin a I just dont want to have to keep putting .admin all the time. Does anyone have any suggestions on how I could do this? I suppose I could write a .net class which sets this up and writes a stylesheet according to whats put into it, but then I would not be able to read the styles so easily add there would be all sorts of like Classes.Add(blah) and so on. Thanks in advance for any replies... Regards, Richard

  • Reference for proper handling of PID file on Unix

    - by bignose
    Where can I find a well-respected reference that details the proper handling of PID files on Unix? On Unix operating systems, it is common practice to “lock” a program (often a daemon) by use of a special lock file: the PID file. This is a file in a predictable location, often ‘/var/run/foo.pid’. The program is supposed to check when it starts up whether the PID file exists and, if the file does exist, exit with an error. So it's a kind of advisory, collaborative locking mechanism. The file contains a single line of text, being the numeric process ID (hence the name “PID file”) of the process that currently holds the lock; this allows an easy way to automate sending a signal to the process that holds the lock. What I can't find is a good reference on expected or “best practice” behaviour for handling PID files. There are various nuances: how to actually lock the file (don't bother? use the kernel? what about platform incompatibilities?), handling stale locks (silently delete them? when to check?), when exactly to acquire and release the lock, and so forth. Where can I find a respected, most-authoritative reference (ideally on the level of W. Richard Stevens) for this small topic?

  • How is jQuery so fast?

    - by ClarkeyBoy
    Hey, I have a rather large application which, on the admin frontend, takes a few seconds to load a page because of all the pageviews that it has to load into objects before displaying anything. Its a bit complex to explain how the system works, but a few of my other questions explains the system in great detail. The main difference between what they say and the current system is that the customer frontend no longer loads all the pageviews into objects when a customer first views the page - it simply adds the pageview to the database and creates an object in an unsynchronised list... to put it simply, when a customer views a page it no longer loads all the pageviews into objects; but the admin frontend still does. I have been working on some admin tools on the customer frontend recently, so if an administrator clicks the description of an item in the catalogue then the right hand column will display statistics and available actions for the selected item. To do this the page which gets loaded (through $('action-container').load(bla bla bla);) into the right hand column has to loop through ALL the pageviews - this ultimately means that ALL the pageviews are loaded into objects if they haven't been already. For some reason this loads really REALLY fast. The difference in speed is only like a second on my dev site, but the live site has thousands of pageviews so the difference is quite big... So my question is: why is it that the admin frontend loads so slowly while using $(bla).load(bla); is so fast? I mean whatever method jQuery uses, can't browsers use this method too and load pages super-fast? Obviously not as someone would've done that by now - but I am interested to know just why the difference is so big... is it just my system or is there a major difference in speed between the browser getting a page and jQuery getting a page? Do other people experience the same kind of differences? Thanks in advance, Regards, Richard

  • OpenCV: Shift/Align face image relative to reference Image (Image Registration)

    - by Abhischek
    I am new to OpenCV2 and working on a project in emotion recognition and would like to align a facial image in relation to a reference facial image. I would like to get the image translation working before moving to rotation. Current idea is to run a search within a limited range on both x and y coordinates and use the sum of squared differences as error metric to select the optimal x/y parameters to align the image. I'm using the OpenCV face_cascade function to detect the face images, all images are resized to a fixed (128x128). Question: Which parameters of the Mat image do I need to modify to shift the image in a positive/negative direction on both x and y axis? I believe setImageROI is no longer supported by Mat datatypes? I have the ROIs for both faces available however I am unsure how to use them. void alignImage(vector<Rect> faceROIstore, vector<Mat> faceIMGstore) { Mat refimg = faceIMGstore[1]; //reference image Mat dispimg = faceIMGstore[52]; // "displaced" version of reference image //Rect refROI = faceROIstore[1]; //Bounding box for face in reference image //Rect dispROI = faceROIstore[52]; //Bounding box for face in displaced image Mat aligned; matchTemplate(dispimg, refimg, aligned, CV_TM_SQDIFF_NORMED); imshow("Aligned image", aligned); } The idea for this approach is based on Image Alignment Tutorial by Richard Szeliski Working on Windows with OpenCV 2.4. Any suggestions are much appreciated.

  • is this valid json array using php

    - by Rich
    Hello, I need to convert some code done by someone else, to work in my mvc model It is using some functions like EOD that I don't understand. Does that still work in a class? Primarely, my question focusus on the json output. The old code does not use the php json_encode function, but outputs it directly like this ?> { "username": "<?php echo $_SESSION['username'];?>", "items": [ <?php echo $items;?> ] } <?php I would do it like this, but I need to be sure it's right for the items part header('Content-type: application/json'); $output = array("username"=> isset( $_SESSION['username'] ) ? $_SESSION['username'] : "?", "items"=>$items ); $this->content = json_encode($output); This is some background on how the $items is made. An item is stored like this: $_SESSION['chatHistory'][$_POST['to']] .= <<<EOD { "s": "1", "f": "{$to}", "m": "{$messagesan}" }, EOD; and it is put in the $items variable like this $items = ''; if ( !empty($_SESSION['openChatBoxes'] ) ) { foreach ( $_SESSION['openChatBoxes'] as $chatbox => $void ) { $items .= $this->chatBoxSession($chatbox); } } //The chatBoxSession() function takes an item from the $_SESSION['chatHistory'] array and returns it. I hope this was somewhat clear enough? The php manual warns that in some cases you don't get an array output, instead you get an object. So, with the EOD syntax, I am not really sure. It could save me some time if I know some things are doing what they supposed too, and giving the right output. thanks, Richard

  • ASP.NET 2.0 RijndaelManaged encryption algorithm vs. FIPS

    - by R Rush
    I'm running into an issue with an ASP.NET 2.0 application. Our network folks just upped our security, and now I get the floowing error whenever I try to access the app: "This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms." I've done a little research, and it sounds like ASP.NET uses the RijndaelManaged AES encryption algorithm to encrypt the ViewState of pages... and RijndaelManaged is on the list of algorithms that aren't FIPS compliant. We're certainly not explicitly calling any encryption algorithm... much less anything on the non-compliant list. This ViewState business makes sense to me, I guess. The thing I can't muddle out, though, is what to do about it. I've found a KB article that suggests using a web.config setting to specify a different algorithm... but either that didn't stick, or that algorithm isn't up to snuff, either. So: 1) Is the RijndaelManaged / ViewState thing actually the problem? Or am I barking up the wrong tree? 2) How to I specify what algorithm to use instead of RijndaelManaged? I've got a list of algorithms that are and aren't compliant; I'm just not sure where to plug that information in. Thanks! Richard

  • Floating point precision in Visual C++

    - by Luigi Giaccari
    HI, I am trying to use the robust predicates for computational geometry from Jonathan Richard Shewchuk. I am not a programmer, so I am not even sure of what I am saying, I may be doing some basic mistake. The point is the predicates should allow for precise aritmthetic with adaptive floating point precision. On my computer: Asus pro31/S (Core Due Centrino Processor) they do not work. The problem may stay in the fact the my computer may use some improvements in the floating point precision taht conflicts with the one used by Shewchuk. The author says: /* On some machines, the exact arithmetic routines might be defeated by the / / use of internal extended precision floating-point registers. Sometimes / / this problem can be fixed by defining certain values to be volatile, / / thus forcing them to be stored to memory and rounded off. This isn't / / a great solution, though, as it slows the arithmetic down. */ Now what I would like to know is that there is a way, maybe some compiler option, to turn off the internal extended precision floating-point registers. I really appriaciate your help

  • Why is it assumed that send may return with less than requested data transmitted on a blocking socke

    - by Ernelli
    The standard method to send data on a stream socket has always been to call send with a chunk of data to write, check the return value to see if all data was sent and then keep calling send again until the whole message has been accepted. For example this is a simple example of a common scheme: int send_all(int sock, unsigned char *buffer, int len) { int nsent; while(len 0) { nsent = send(sock, buffer, len, 0); if(nsent == -1) // error return -1; buffer += nsent; len -= nsent; } return 0; // ok, all data sent } Even the BSD manpage mentions that ...If no messages space is available at the socket to hold the message to be transmitted, then send() normally blocks... Which indicates that we should assume that send may return without sending all data. Now I find this rather broken but even W. Richard Stevens assumes this in his standard reference book about network programming, not in the beginning chapters, but the more advanced examples uses his own writen (write all data) function instead of calling write. Now I consider this still to be more or less broken, since if send is not able to transmit all data or accept the data in the underlying buffer and the socket is blocking, then send should block and return when the whole send request has been accepted. I mean, in the code example above, what will happen if send returns with less data sent is that it will be called right again with a new request. What has changed since last call? At max a few hundred CPU cycles have passed so the buffer is still full. If send now accepts the data why could'nt it accept it before? Otherwise we will end upp with an inefficient loop where we are trying to send data on a socket that cannot accept data and keep trying, or else? So it seems like the workaround, if needed, results in heavily inefficient code and in those circumstances blocking sockets should be avoided at all an non blocking sockets together with select should be used instead.

  • Server.Execute(path).. executed page returns the calling pages' url from request.url..

    - by ClarkeyBoy
    Hey, As explained in the title, I am having a problem with getting the URL of the page being executed from within a page. Basically I have a dynamic catalogue, where customers select products they are interested in. The manager of the company I am doing this for would like to be able to create an up to date offline catalogue at any given time, to send out to customers who dont have an internet connection. So far its going really well. I am using Server.Execute to get the content for each page, then putting it in static html pages and changing the dynamic links to static html links (ie changing all aspx links to htm). I am able to output all the pages for about us, contact us, home, and the entire catalogue. However, one of the stylesheets which is included in the page based on the URL (if the page is in the administration section then it is not included, otherwise it is) is not being included in the pages when it should be. I have tried outputting the URL but it just returns the URL of the calling page, not the page being called. Does anyone have any idea why this is happening? Any help would be greatly appreciated. Regards, Richard Clarke

  • Django: Serving Media Behind Custom URL

    - by TheLizardKing
    So I of course know that serving static files through Django will send you straight to hell but I am confused on how to use a custom url to mask the true location of the file using Django. http://stackoverflow.com/questions/2681338/django-serving-a-download-in-a-generic-view but the answer I accepted seems to be the "wrong" way of doing things. urls.py: url(r'^song/(?P<song_id>\d+)/download/$', song_download, name='song_download'), views.py: def song_download(request, song_id): song = Song.objects.get(id=song_id) fsock = open(os.path.join(song.path, song.filename)) response = HttpResponse(fsock, mimetype='audio/mpeg') response['Content-Disposition'] = "attachment; filename=%s - %s.mp3" % (song.artist, song.title) return response This solution works perfectly but not perfectly enough it turns out. How can I avoid having a direct link to the mp3 while still serving through nginx/apache? EDIT 1 - ADDITIONAL INFO Currently I can get my files by using an address such as: http://www.example.com/music/song/1692/download/ But the above mentioned method is the devil's work. How can I accomplished what I get above while still making nginx/apache serve the media? Is this something that should be done at the webserver level? Some crazy mod_rewrite? http://static.example.com/music/Aphex%20Twin%20-%20Richard%20D.%20James%20(V0)/10%20Logon-Rock%20Witch.mp3

  • How best to implement "favourites" feature? (like favourite products on a data driven website)

    - by ClarkeyBoy
    Hi, I have written a dynamic database driven, object oriented website with an administration frontend etc etc. I would like to add a feature where customers can save items as "favourites", without having to create an account and login, to come back to them later, but I dont know how exactly to go about doing this... I see three options: Log favourites based on IP address and then change these to be logged against an account if the customer then creates an account; Force customers to create an account to be able to use this functionality; Log favourites based on IP address but give users the option to save their favourites under a name they specify. The problem with option 1 is that I dont know much about IP addresses - my Dad thinks they are unique, but I know people have had problems with systems like this. The problem with 1 and 2 is that accounts have not been opened up to customers yet - only administrators can log in at the moment. It should be easy to alter this (no more than a morning or afternoons work) but I would also have to implement usergroups too. The problem with option 3 is that if user A saves a favourites list called "My Favourites", and then user B tries to save a list under this name and it is refused, user B will then be able to access the list saved by user A because they now know it already exists. A solution to this is to password protect lists, but to go to all this effort I may as well implement option 2. Of course I could always use option 4; use an alternative if anyone can suggest a better solution than any of the above options. So has anyone ever done something like this before? If so how did you go about it? What do you recommend (or not recommend)? Many thanks in advance, Regards, Richard
