  • Maximum Availability with Oracle GoldenGate

    - by Irem Radzik
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Oracle Database offers a variety of built-in and optional products for maximum availability, and it is well known for its robust high availability and disaster recovery solutions. With its heterogeneous, real-time, transactional data movement capabilities, Oracle GoldenGate is a key part of the Maximum Availability Architecture for Oracle Database. This week on Thursday Dec. 13th we will be presenting in a live webcast how Oracle GoldenGate fits into Oracle Database Maximum Availability Architecture (MAA). Joe Meeks from the Oracle Database High Availability team will discuss how Oracle GoldenGate complements other key products within MAA such as Active Data Guard. Nick Wagner from GoldenGate PM team will present how to upgrade to latest Oracle Database release without any downtime. Nick will also cover 2 new features of  Oracle GoldenGate 11gR2:  Integrated Capture for Oracle Database and Automated Conflict Detection and Resolution. Nick will provide in depth review of these new features with examples. Oracle GoldenGate also offers maximum availability for non-Oracle databases, such as HP NonStop, SQL Server, DB2 (LUW, iSeries, or zSeries) and more. The same robust, reliable real-time, bidirectional data movement capabilities apply to all supported databases.  I'd like to invite you to join us on Thursday Dec. 13th 10am PT/1pm ET to hear from the product experts on how to use GoldenGate for maximizing database availability and to ask your questions.

  • Java based webservices

    - by java_mouse
    We are working on a big java project and as a second phase in this project, we will have to develop some web services that the clients can call and get or update the data in our database. Though I have been a Java programmer for a while, I have never worked on web services yet. I develop EJBs, data services layer etc but have not worked in web services yet. What are the current standards in developing web services in Java platform? What is the best and recommended way for developing web-services? Any input/link will be appreciated

  • Test your internet connection - Emtel Mobile Internet

    After yesterday's report on Emtel Fixed Broadband (I'm still wondering where the 'fixed' part is), I did the same tests on Emtel Mobile Internet. For this I'm using the Huawei E169G HSDPA USB stick, connected to the same machine. Actually, this is my fail-safe internet connection and the system automatically switches between them if a problem, let's say timeout, etc. has been detected on the main line. For better comparison I used exactly the same servers on Speedtest.net. The results Following are the results of Rose Hill (hosted by Emtel) and respectively Frankfurt, Germany (hosted by Vodafone DE): Speedtest.net result of 31.05.2013 between Flic en Flac and Rose Hill, Mauritius (Emtel - Mobile Internet) Speedtest.net result of 31.05.2013 between Flic en Flac and Frankfurt, Germany (Emtel - Mobile Internet) As you might easily see, there is a big difference in speed between national and international connections. More interestingly are the results related to the download and upload ratio. I'm not sure whether connections over Emtel Mobile Internet are asymmetric or symmetric like the Fixed Broadband. Might be interesting to find out. The first test result actually might give us a clue that the connection could be asymmetric with a ratio of 3:1 but again I'm not sure. I'll find out and post an update on this. It depends on network coverage Later today I was on tour with my tablet, a Samsung Galaxy Tab 10.1 (model GT-P7500) running on Android 4.0.4 (Ice Cream Sandwich), and did some more tests using the Speedtest.net app. The results are actually as expected and in areas with better network coverage you will get better results after all. At least, as long as you stay inside the national networks. For anything abroad, it doesn't really matter. But see for yourselves: Speedtest.net result of 31.05.2013 between Cascavelle and servers in Rose Hill, Mauritius (Emtel - Mobile Internet), Port Louis, Mauritius and Kuala Lumpur, Malaysia It's rather shocking and frustrating to see how the speed on international destinations goes down. And the full capability of the tablet's integrated modem (HSDPA: 21 Mbps; HSUPA: 5.76 Mbps) isn't used, too. I guess, this demands more tests in other areas of the island, like Ebene, Pailles or Port Louis. I'll keep you updated... The question remains: Alternatives? After the publication of the test results on Fixed Broadband I had some exchange with others on Facebook. Sadly, it seems that there are really no alternatives to what Emtel is offering at the moment. There are the various internet packages by Mauritius Telecom feat. Orange, like ADSL, MyT and Mobile Internet, and there is Bharat Telecom with their Bees offer which is currently limited to Ebene and parts of Quatre Bornes.

  • file copy error from system to cifs mount

    - by dwpriest
    When coping a file greater than 64kB from an Ubuntu server to a CIFS mounted windows share, most of the data is copied, but it seems the last chunk doesn't get copied. The size doesn't match, and the md5 check sums don't match. I have plenty of file space, but then I use cp, I get the following... cp: closing `cloudBackup/asdf.txt': No space left on device Using rsync, I get the following... rsync: close failed on "/home/fluffy/cloudBackup/.asdf.txt.qrBWe6": No space left on device (28) rsync error: error in file IO (code 11) at receiver.c(752) [receiver=3.0.8] rsync: connection unexpectedly closed (29 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at io.c(601) [sender=3.0.8] I have full read/write permissions on the mounted share. I can copy locally and between the mount and system via SSH just fine. Any ideas? Thank you

  • structure problem in Relational DBMS creation

    - by Kane
    For learning and understanding purpose, I currently want to try to make a small relational DBMS with simple features like (for now) only sequential reading/writing and CREATE TABLE, INSERT, SELECT, UPDATE and DELETE management. I am currently on the "think" part of the project and I am stuck on the way to store the read data in memory. First I was thinking of putting them properly on a structure, but the problem is that tables are all different, know the type of each column is not an issue, but I am not sure C provide a way to make fully dynamic structure. My second and current idea is to make a simple char array of the required length and just get the data by order with cast. But I am not sure if it is the good way to do that part, so I wanted to ask for your opinion and advices about that. Thanks in advance for your help. nb: I hope my question is enough clear and understandable, I still lack of pratice in english

  • An Epic Question "How to call a method when the page loads"

    - by Arunkumar Ramamoorthy
    Quite often, there comes a question in OTN, with different subjects, all meaning "How to call a method when my ADF page loads?". More often, people tend to take the approach of ADF Phase Listener by overriding before/afterPhase methods.In this blog, we will go through different options in achieving it.1. Method Call Activity as default activity in Taskflow :If the application is built with taskflows, then this is the best suited approach to take. 1.a. Calling a Data Control Method :To call a Data Control method (ex: A method in AMImpl exposed as client interface), simply Drag and Drop the method as Default Method Call Activity, then draw a control flow case from the method to your page. Once after this, drop the taskflow as region in main page. When we run the main page, the Method Call Activity would be called first, and then the page will be rendered.1.b. Calling a Method in Backing Bean: To call a method in the backing bean before pageload, we can follow the similar approach as above. Instead of binding the Method Call Activity to an action/method binding in pagedef, we bind to the method. Insert a Method Call Activity (and make it as default) from the Component Palette. Double click on to select a method to bind. This approach can also be used, to perform some action in backing bean along with calling a method Data Control (just need to add bindings code in backing bean to execute DC method). 2. Using invokeAction Executable :If the application is built with pages and no taskflows are involved, then this option can be taken into consideration.In the page definition of the page, add an invokeAction Executable and bind it to the method needed to be executed. 3. Using combination of Server and Client Listeners : If the page does not have any page definition, then to call a method in backing bean, this approach can be taken. In this, a serverListener would be added at the document level, which would be calling the method in backing bean. Along with this, a clientListener would be added with "load" type (i.e will be triggered when the page loads), which would queue a serverEvent to trigger the method. 4. Using Page Phase Listener :This should be the last resort. Care should be taken when using this approach since the Phase Listener would be called for each request sent by the client.Zeeshan Baig's blog covers this scenario.

  • Learn programming backwards, or "so I failed the FizzBuzz test. Now what?"

    - by moraleida
    A Little Background I'm 28 today, and I've never had any formal training in software development, but I do have two higher education degrees equivalent to a B.A in Public Relations and an Executive MBA focused on Project Management. I've worked on those fields for about 6 years total an then, 2,5 years ago I quit/lost my job and decided to shift directions. After a month thinking things through I decided to start freelancing developing small websites in WordPress. I self-learned my way into it and today I can say I run a humble but successful career developing themes and plugins from scratch for my clients - mostly agencies outsourcing some of their dev work for medium/large websites. But sometimes I just feel that not having studied enough math, or not having a formal understanding of things really holds me behind when I have to compete or work with more experienced developers. I'm constantly looking for ways to learn more but I seem to lack the basics. Unfortunately, spending 4 more years in Computer Science is not an option right now, so I'm trying to learn all I can from books and online resources. This method is never going to have NASA employ me but I really don't care right now. My goal is to first pass the bar and to be able to call myself a real programmer. I'm currently spending my spare time studying Java For Programmers (to get a hold on a language everyone says is difficult/demanding), reading excerpts of Code Complete (to get hold of best practices) and also Code: The Hidden Language of Computer Hardware and Software (to grasp the inner workings of computers). TL;DR So, my current situation is this: I'm basically capable of writing any complete system in PHP (with the help of Google and a few books), integrating Ajax, SQL and whatnot, and maybe a little slower than an experienced dev would expect due to all the research involved. But I was stranded yesterday trying to figure out (not Google) a solution for the FizzBuzz test because I didn't have the if($n1 % $n2 == 0) method modulus operator memorized. What would you suggest as a good way to solve this dilemma? What subjects/books should I study that would get me solving problems faster and maybe more "in a programmers way"? EDIT - Seems that there was some confusion about what did I not know to solve FizzBuzz. Maybe I didn't express myself right: I knew the steps needed to solve the problem. What I didn't memorize was the modulus operator. The problem was in transposing basic math to the program, not in knowing basic math. I took the test for fun, after reading about it on Coding Horror. I just decided it was a good base-comparison line between me and formally-trained devs. I just used this as an example of how not having dealt with math in a computer environment before makes me lose time looking up basic things like modulus operators to be able to solve simple problems.

  • Proper way to measure the scalability of web Application

    - by Jorge
    Let's say that I have a web Application where i'm going to have 300 users and each one have to see data on real time, imagine that each client make an ajax call to the server to see in real time what's happens with the changes of the data, this calls are made each 300 ms per user. I know that i can run a simulation to see if the hardware of my server supports this example. But what happen's if the number of users start to grow up. Is there a way that i can measure the hardware needed to handle this growing behavior, a software, a formula, algorithm or maybe recommend me if i need to implement an distributed application with multiplies servers and balance the loads.

  • Do you use your personal laptop for work?

    - by davekaro
    We're trying to get our company to let us use our own personal laptop for client work. We've agreed that any code/data will be encrypted using something like TrueCrypt, in case the laptop is stolen or lost. However, the company is still skeptical and not sure they want to allow us to use our personal machines for development. They would rather buy us laptops... but we want to use MacBook Pros and they don't want to pay for them. Even if they did buy us laptops, we would stil have the issue of needing to encrypt the code/data in case of theft/loss. Do you use your own laptop for work? What are the arguments for/against this?

  • Northwind now available on SQL Azure

    - by jamiet
    Two weeks ago I made available a copy of [AdventureWorks2012] on SQL Azure and published credentials so that anyone from the SQL community could connect up and experience SQL Azure, probably for the first time. One of the (somewhat) popular requests thereafter was to make the venerable Northwind database available too so I am pleased to say that as of right now, Northwind is up there too. You will notice immediately that all of the Northwind tables (and the stored procedures and views too) have been moved into a schema called [Northwind] – this was so that they could be easily differentiated from the existing [AdventureWorks2012] objects. I used an SQL Server Data Tools (SSDT) project to publish the schema and data up to this SQL Azure database; if you are at all interested in poking around that SSDT project then I have made it available on Codeplex for your convenience under the MS-PL license – go and get it from https://northwindssdt.codeplex.com/. Using SSDT proved particularly useful as it alerted me to some aspects of Northwind that were not compatible with SQL Azure, namely that five of the tables did not have clustered indexes: The beauty of using SSDT is that I am alerted to these issues before I even attempt a connection to SQL Azure. Pretty cool, no? Fixing this situation was of course very easy, I simply changed the following primary keys from being nonclustered to clustered: [PK_Region] [PK_CustomerDemographics] [PK_EmployeeTerritories] [PK_Territories] [PK_CustomerCustomerDemo]   If you want to connect up then here are the credentials that you will need: Server mhknbn2kdz.database.windows.net Database AdventureWorks2012 User sqlfamily Password sqlf@m1ly You will need SQL Server Management Studio (SSMS) 2008R2 installed in order to connect or alternatively simply use this handy website: https://mhknbn2kdz.database.windows.net which provides a web interface to a SQL Azure server.

  • Solutions for software using many calls to a server

    - by Val
    I am developing software that uses many calls to a server. On a client side it's a Silverlight application. Almost every time a user clicks on a button in it, it sends 1-5 WCF calls to a server. There can be up to dozen or so users at a time. The server is a database server that serves data to a client. I am an intermediate level developer and am thinking about caching some data and syncing my changes from time to time. Are there any official solutions or technologies for it, like, patterns and such?

  • Internal and external API architecture

    - by Tacomanator
    The company I work for maintains a successful SaaS product that grew "organically" over the years. We are planning to expand the line with a suite of new products that will share data with the existing product. To support this, we are looking to consolidate business logic into a single place: a web service layer. The WS layer will be used by: The web applications A tool to import data A tool to integrate with other client software (not an API per se) We also want to create an API that can be used by our customers that are capable of using it to create their own integrations. We are struggling with the following question: Should the internal API (aka the WS layer) and the external API be one in the same, with security and permission settings to control what can be done by who, or should they be two separate applications where the external API just calls the internal API like any other application? So far in our debate it seems that separating them may be more secure, but will add overhead. What have others done in a similar situation?

  • Educause Top-Ten IT Issues - the most change in a decade or more

    - by user739873
    The Education IT Issue Panel has released the 2012 top-ten issues facing higher education IT leadership, and instead of the customary reshuffling of the same deck, the issues reflect much of the tumult and dynamism facing higher education generally.  I find it interesting (and encouraging) that at the top of this year's list is "Updating IT Professionals' Skills and Roles to Accommodate Emerging Technologies and Changing IT Management and Service Delivery Models."  This reflects, in my view, the realization that higher education IT must change in order to fully realize the potential for transforming the institution, and therefore it's people must learn new skills, understand and accept new ways of solving problems, and not be tied down by past practices or institutional inertia. What follows in the remaining 9 top issues all speak, in some form or fashion, to the need for dramatic change, but not just in the areas of "funding IT" (code for cost containment or reduction), but rather the need to increase effectiveness and efficiency of the institution through the use of technology—leveraging the wave of BYOD (Bring Your Own Device) to the institution's advantage, rather than viewing it as a threat and a problem to be contained. Although it's #10 of 10, IT Governance (and establishment and implementation of the governance model throughout the institution) is key to effectively acting upon many of the preceding issues in this year's list.  In the majority of cases, technology exists to meet the needs and requirements to effectively address many of the challenges outlined in top-ten issues list. Which brings me to my next point. Although I try not to sound too much like an Oracle commercial in these (all too infrequent) blog posts, I can't help but point out how much confluence there is between several of the top issues this year and what my colleagues and I have been evangelizing for some time. Starting from the bottom of the list up: 1) I'm gratified that research and the IT challenges it presents has made the cut.  Big Data (or Large Data as it's phased in the report) is rapidly going to overwhelm much of what exists today even at our most prepared and well-equipped research universities.  Combine large data with the significantly more stringent requirements around data preservation, archiving, sharing, curation, etc. coming from granting agencies like NSF, and you have the brewing storm that could result in a lot of "one-off" solutions to a problem that could very well be addressed collectively and "at scale."   2) Transformative effects of IT – while I see more and more examples of this, there is still much more that can be achieved. My experience tells me that culture (as the report indicates or at least poses the question) gets in the way more than technology not being up to task.  We spend too much time on "context" and not "core," and get lost in the weeds on the journey to truly transforming the institution with technology. 3) Analytics as a key element in improving various institutional outcomes.  In our work around Student Success, we see predictive "academic" analytics as essential to getting in front of the Student Success issue, regardless of how an institution or collections of institutions defines success.  Analytics must be part of the fabric of the key academic enterprise applications, not a bolt-on.  We will spend a significant amount of time on this topic during our semi-annual Education Industry Strategy Council meeting in Washington, D.C. later this month. 4) Cloud strategy for the broad range of applications in the academic enterprise.  Some of the recent work by Casey Green at the Campus Computing Survey would seem to indicate that there is movement in this area but mostly in what has been termed "below the campus" application areas such as collaboration tools, recruiting, and alumni relations.  It's time to get serious about sourcing elements of mature applications like student information systems, HR, Finance, etc. leveraging a model other than traditional on-campus custom. I've only selected a few areas of the list to highlight, but the unifying theme here (and this is where I run the risk of sounding like an Oracle commercial) is that these lofty goals cry out for partners that can bring economies of scale to bear on the problems married with a deep understanding of the nuances unique to higher education.  In a recent piece in Educause Review on Student Information Systems, the author points out that "best of breed is back". Unfortunately I am compelled to point out that best of breed is a large part of the reason we have made as little progress as we have as an industry in advancing some of the causes outlined above.  Don't confuse "integrated" and "full stack" for vendor lock-in.  The best-of-breed market forces that Ron points to ensure that solutions have to be "integratable" or they don't survive in the marketplace. However, by leveraging the efficiencies afforded by adopting solutions that are pre-integrated (and possibly metered out as a service) allows us to shed unnecessary costs – as difficult as these decisions are to make and to drive throughout the organization.

  • Which is the most practical way to add functionality to this piece of code?

    - by Adam Arold
    I'm writing an open source library which handles hexagonal grids. It mainly revolves around the HexagonalGrid and the Hexagon class. There is a HexagonalGridBuilder class which builds the grid which contains Hexagon objects. What I'm trying to achieve is to enable the user to add arbitrary data to each Hexagon. The interface looks like this: public interface Hexagon extends Serializable { // ... other methods not important in this context <T> void setSatelliteData(T data); <T> T getSatelliteData(); } So far so good. I'm writing another class however named HexagonalGridCalculator which adds some fancy pieces of computation to the library like calculating the shortest path between two Hexagons or calculating the line of sight around a Hexagon. My problem is that for those I need the user to supply some data for the Hexagon objects like the cost of passing through a Hexagon, or a boolean flag indicating whether the object is transparent/passable or not. My question is how should I implement this? My first idea was to write an interface like this: public interface HexagonData { void setTransparent(boolean isTransparent); void setPassable(boolean isPassable); void setPassageCost(int cost); } and make the user implement it but then it came to my mind that if I add any other functionality later all code will break for those who are using the old interface. So my next idea is to add annotations like @PassageCost, @IsTransparent and @IsPassable which can be added to fields and when I'm doing the computation I can look for the annotations in the satelliteData supplied by the user. This looks flexible enough if I take into account the possibility of later changes but it uses reflection. I have no benchmark of the costs of using annotations so I'm a bit in the dark here. I think that in 90-95% of the cases the efficiency is not important since most users wont't use a grid where this is significant but I can imagine someone trying to create a grid with a size of 5.000.000.000 X 5.000.000.000. So which path should I start walking on? Or are there some better alternatives? Note: These ideas are not implemented yet so I did not pay too much attention to good names.

  • CSV files not being written

    - by Kamalpreet
    I worked on a small project in which the data entered in HTML forms was saved in a CSV file which was used subsequently. The files were run on Apache2. It worked fine. After about 25 days, when I reopened the project, the data entered in forms was not saved in CSV file. I checked all the permissions. I even sent a zip file of my files to one of m friends. It worked well on his system. So should I figure it out there's some problem in the system. I am using Ubuntu 13.04. Kindly suggest me something so that I am able to figure out the problem.

  • What is the correct way to use g_signal_connect() in C++ for dynamic unity quicklists?

    - by hakermania
    I want to make my application use dynamic unity quicklists. For building my application I am using C++ and the QtCreator IDE. When a menu action is triggered I want to be able to have access to a non-static function of my MainWindow class so as to be able to update the Graphical User Interface which can be accessed from inside 'normal' MainWindow's functions. So, I am building up my quicklist like this (mainwindow.cpp): void MainWindow::enable_unity_quicklist(){ Unity_Menu = dbusmenu_menuitem_new(); dbusmenu_menuitem_property_set_bool (Unity_Menu, DBUSMENU_MENUITEM_PROP_VISIBLE, FALSE); Unity_Stop = dbusmenu_menuitem_new(); dbusmenu_menuitem_property_set(Unity_Stop, DBUSMENU_MENUITEM_PROP_LABEL, "Stop"); dbusmenu_menuitem_child_append (Unity_Menu, Unity_Stop); g_signal_connect (Unity_Stop, DBUSMENU_MENUITEM_SIGNAL_ITEM_ACTIVATED, G_CALLBACK(&fake_callback), (gpointer)this); if(!unity_entry) unity_entry = unity_launcher_entry_get_for_desktop_id("myapp.desktop"); unity_launcher_entry_set_quicklist(unity_entry, Unity_Menu); dbusmenu_menuitem_property_set_bool(Unity_Menu, DBUSMENU_MENUITEM_PROP_VISIBLE, true); dbusmenu_menuitem_property_set_bool(Unity_Stop, DBUSMENU_MENUITEM_PROP_VISIBLE, true); } void MainWindow::fake_callback(gpointer data){ MainWindow* m = (MainWindow*)data; m->on_stopButton_clicked(); } void MainWindow::on_stopButton_clicked(){ //stopping the process... } mainwindow.h: private slots: void enable_unity_quicklist(); void on_stopButton_clicked(); public slots: static void fake_callback(gpointer data); This suggestion was taken from http://old.nabble.com/Using-g_signal_connect-in-class-td18461823.html The program crashes immediately after I choose the 'Stop' action from the Unity Quicklist. Debugging the program shows that I am not able to access anything MainWindow related inside the on_stopButton_clicked() without crashing. For example, it crashes when doing this check (which is the first 2 lines of code inside this function): if (!ui->stopButton->isEnabled()) return; I have also tested lots of other things that I found at the internet, but nothing of them worked. One interesting solution would be to use gtkmm (http://developer.gnome.org/gtkmm-tutorial/stable/sec-connecting-signal-handlers.html.en) but I am not used at all working on GTK applications (I work solely in Qt) and I don't know if this even suits to my occasion. A compilable example indicating what the problem is can be found at: http://ubuntuone.com/7iKA3wnPmWVp8YNNDLlVQI (3.2Kb) If you are not familiar with the QtCreator IDE, you can compile with the following commands, as long as you have all the needed libraries: cd dynamic_unity_quicklists_test; qmake -project; qmake; make
