  • JEOS

    - by john.graves(at)oracle.com
    JEOS stands for Just Enough Operating System.  It is  great environment for building virtual machines without all the clutter of a windowing system, games, office products, etc.  It is from Ubuntu and you install it using the Ubuntu server install, but rather than picking a standard install, press F4 and choose “Install a minimal system.” Note: The “Install a minimal virtual machine” is specific to VMWare and I plan to use VirtualBox. Be sure to include Open SSH in the install so that it installs sshd. *** Also, if you plan to install XE, you’ll need to modify the partitions to have a larger swap space (at least 1.5 G). *** Once the install is done, I find it useful to install a few other items. Update Ubuntu apt-get update Install some other tools apt-get openjdk-6-jre Yes, java will be included in any of the WebLogic installs, but I need this one if I want to do remote display (for config wizards, etc). apt-get gcc Some apps require to rebuild the kernel modules, so you’ll need a basic compiler. Install guest additions (Choose the VirtualBox Devices->Install Guest Additions…” option.  This sets up a /dev/cdrom or /dev/cdrom1.  You’ll need to manually mount this temporarily: sudo mount /dev/cdrom /mnt Then run the linux .bin file. Update nofile limits.  Most java apps fail with the standard ubuntu settings: edit /etc/security/limits.conf and add these lines at the end: *     soft nofile 65535 *     hard nofile 65535 root  soft nofile 65535 root  hard nofile 65535 These numbers are very high and I wouldn’t do this on a production system, but for this environment it is fin. To get rid of the annoying piix error on boot, add the following line to the /etc/modprobe.d/blacklist.conf file blacklist i2c_piix4

  • Windows Phone 8 Announcement

    - by Tim Murphy
    As if the Surface announcement on Monday wasn’t exciting enough, today Microsoft announce that Windows Phone 8 will be coming this fall.  That itself is great news, but the features coming were like confetti flying in all different directions.  Given this speed I couldn’t capture every feature they covered.  A summary of what I did capture is listed below starting with their eight main features. Common Core The first thing that they covered is that Windows Phone 8 will share a core OS with Windows 8.  It will also run natively on multiple cores.  They mentioned that they have run it on up to 64 cores to this point.  The phones as you might expect will at least start as dual core.  If you remember there were metrics saying that Windows Phone 7 performed operations faster on a single core than other platforms did with dual cores.  The metrics they showed here indicate that Windows Phone 8 runs faster on comparable dual core hardware than other platforms. New Screen Resolutions Screen resolution has never been an issue for me, but it has been a criticism of Windows Phone 7 in the media.  Windows Phone 8 will supports three screen resolutions: WVGA 800 x 480, WXGA 1280 x 768, and 720 1280x720.  Hopefully this makes pixel counters a little happier. MicroSD Support This was one of my pet peeves when I got my Samsung Focus. With Windows Phone 8 the operating system will support adding MicroSD cards after initial setup.  Of course this is dependent on the hardware company on implementing it, but I think we have seen that even feature phone manufacturers have not had a problem supporting this in the past. NFC NFC has been an anticipated feature for some time.  What Microsoft showed today included the fact that they didn’t just want it to be for the phone.  There is cross platform NFC functionality between Windows Phone 8 and Windows 8.  The demos , while possibly a bit fanciful, showed would could be achieved even in a retail environment.  We are getting closer and closer to a Minority Report world with these technologies. Wallet Windows Phone 8 isn’t the first platform to have a wallet concept.  What they have done to differentiate themselves is to make it sot that it is not dependent on a SIM type chip like other platforms.  They have also expanded the concept beyond just banks to other types of credits such as airline miles. Nokia Mapping People have been envious of the Lumia phones having the Nokia mapping software.  Now all Windows Phone 8 devices will use NavTeq data and will have the capability to run in an offline fashion.  This is a major step forward from the Bing “touch for the next turn” maps. IT Administration The lack of features for enterprise administration and deployment was a complaint even before the Windows Phone 7 was released.  With the Windows Phone 8 release such features as Bitlocker and Secure boot will be baked into the OS. We will also have the ability to privately sign and distribute applications. Changing Start Screen Joe Belfiore made a big deal about this aspect of the new release.  Users will have more color themes available to them and the live tiles will be highly customizable. You will have the ability to resize and organize the tiles in a more dynamic way.  This allows for less important tiles or ones with less information to be made smaller.  And There Is More So what other tidbits came out of the presentation?  Later this summer the API for WP8 will be available.  There will be developer events coming to a city near you.  Another announcement of interest to developers is the ability to write applications at a native code level.  This is a boon for game developers and those who need highly efficient applications. As a topper on the cake there was mention of in app payment. On the consumer side we also found out that all updates will be available over the air.  Along with this came the fact that Microsoft will support all devices with updates for at least 18 month and you will be able to subscribe for early updates.  Update coming for Windows Phone 7.5 customers to WP7.8.  The main enhancement will be the new live tile features.  The big bonus is that the update will bypass the carriers.  I would assume though that you will be brought up to date with all previous patches that your carrier may not have released. There is so much more, but that is enough for one post.  Needless to say, EXCITING! del.icio.us Tags: Windows Phone 8,WP8,Windows Phone 7,WP7,Announcements,Microsoft

  • Start frei für die Exadata Community im neuen Look!

    - by Frank Schneede (Exadata Community)
    Endlich ist es soweit! Pünktlich mit dem Start der DOAG Konferenz 2012, die vom 20.11. - 22.11.2012 in Nürnberg stattfindet, geht die Deutsche Exadata Community in völlig neu gestaltetem Outfit an den Start. Sie werden hier regelmäßig über neue Ankündigungen sowie Tipps und Tricks im Umgang mit Exadata informiert. Durch das freiere Blogformat werden an dieser Stelle auch Berichte über Exadata Projekte erscheinen, die besonders hervorhebenswert sind. Ich denke, Sie dürfen gespannt sein! Vieles hat sich seit dem letzten Update in der Community getan, denn auf der diesjährigen Oracle Open World in San Franzisco wurde eine ganze Reihe spannender Ankündigungen rund um Exadata gemacht. Die kürzlich vorgestellten Modelle Exadata Database Machine X3-2 und X3-8 sind in der grundlegenden Architektur zwar unverändert geblieben, jedoch sind die Modelle mit aktuellen Prozessoren in SandyBridge Mikroprozessorarchitektur noch leistungsfähiger als bisher. Der vierfach vergrößerte Flash Cache nimmt wesentlich mehr Daten auf und macht die Exadata so zur "In-Memory" Database Machine. Mit der neuen Exadata Software 11.2.3.2 kann der Flash Cache nun als persistenter Write Back Flash Cache verwendet werden. Durch das neuartige Caching profitieren auch OLTP Applikationen, die eine hohe Last von schreibenden Transaktionen verursachen, stärker von der Exadata Technologie. Ein neues Einstiegsmodell, das Exadata X3-2 Eighth Rack, vervollständigt die Produktfamilie und senkt abermals die Einstiegshürde für die Kunden.  Die beiden Community Tipps zur Exadata Hardware wurden aktualisiert. Lesen Sie alles über die Exadata Database Machine X3-2 und deren große Schwester, die Exadata Database Machine X3-8.

  • Java Champion Dick Wall Explores the Virtues of Scala (otn interview)

    - by Janice J. Heiss
    In a new interview up on otn/java, titled “Java Champion Dick Wall on the Virtues of Scala (Part 2),” Dick Wall explains why, after a long career in programming exploring Lisp, C, C++, Python, and Java, he has finally settled on Scala as his language of choice. From the interview: “I was always on the lookout for a language that would give me both Python-like productivity and simplicity for just writing something and quickly having it work and that also offers strong performance, toolability, and type safety (all of which I like in Java). Scala is simply the first language that offers all those features in a package that suits me. Programming in Scala feels like programming in Python (if you can think it, you can do it), but with the benefit of having a compiler looking over your shoulder and telling you that you have the wrong type here or the wrong method name there.The final ‘aha!’ moment came about a year and a half ago. I had a quick task to complete, and I started writing it in Python (as I have for many years) but then realized that I could probably write it just as fast in Scala. I tried, and indeed I managed to write it just about as fast.”Wall makes the remarkable claim that once Java developers have learned to work in Scala, when they work on large projects, they typically find themselves more productive than they are in Java. “Of course,” he points out, “people are always going to argue about these claims, but I can put my hand over my heart and say that I am much more productive in Scala than I was in Java, and I see no reason why the many people I know using Scala wouldn’t say the same without some reason.”Read the interview here.

  • Translating Fusion Apps Customizations: Composers mean Usable Apps in Any Language

    - by ultan o'broin
    Quick shoutout for the Fusion Applications (Cloud Applications to you) Developer Relations blog post about translating Fusion apps customizations using composers and other tools and utilities provided by Oracle. Great to see Fusion help customizations included in the post, as well as software, and it also includes a nice heads up on what's coming to enable customers to make changes to text themselves in Release 8 of Oracle's Cloud Applications. I am proud to say that I logged the enhancements for what's coming in Release 8  to come to life and also wrote a spec for its requirements based on the customer research done internationally through the Oracle Usability Advisory Board). Remember,  copywriting is design and translated versions means reflecting local UX requirements too! Nice post guys!

  • Who keeps removing that file?

    - by mgerdts
    Over the years, I've had many times when some file gets removed and there's no obvious culprit.  With dtrace, it is somewhat easy to figure out:  #! /usr/sbin/dtrace -wqs syscall::unlinkat:entry /cleanpath(copyinstr(arg1)) == "/dev/null"/ {         stop();         printf("%s[%d] stopped before removing /dev/null\n", execname, pid);         system("ptree %d; pstack %d", pid, pid); } That script will stop the process trying to remove /dev/null before it does it.  You can allow it to continue by restarting (unstopping?) the command with prun(1) or killing it with kill -9.  If you want the command to continue automatically after getting the ptree and pstack output, you can add "; prun %d" and another pid argument to the system() call.

  • Get Fanatical About Your Followers

    - by Mike Stiles
    In the fourth of our series of discussions with Aberdeen’s Trip Kucera, we touch on what fans of your brand have come to expect in exchange for their fandom. Spotlight: Around the Oracle Social office, we live for football. So when we think of a true “fan” of a brand, something on the level of a football fan is what comes to mind. But are brands trying to invest fans on that same level? Trip: Yeah, if you’re a football fan, this is definitely your time of year. And if you’ve been to any NFL games recently, especially if you hadn’t been for a few years previously, you may have noticed that from the cup holders to in-stadium Wi-Fi, there’s an increasing emphasis being placed on “fan-focused” accommodations. That’s what they’re known as in the stadium business. Spotlight: How are brands doing in that fan-focused arena? Trip: Remember fan is short for “fanatical.” Brands can definitely learn from the way teams have become fanatical about their fans, or in the social media world, their followers. Many companies consider a segment of their addressable social audience as true fans; I’ve even heard the term “super-fans” used. So just as fans know and can tell you nearly everything about their favorite team, our research shows that there’s a lot value from getting to know your social audience—your followers—at a deeper level. Spotlight: So did your research show there’s a lot to be gained by making fandom a two-way street? Trip: Aberdeen’s new social relationship management research suggests that companies should develop capabilities to better analyze their social audience at a more granular level. Countless “ripped from the headlines” examples, from “United Breaks Guitars” to the most recent British Airways social fiasco we talked about a few weeks ago show how social can magnify the impact of a single customer voice. Spotlight: So how do the companies who are executing social most successfully do that? Trip: Leaders, which are the top-performing companies in Aberdeen’s study, are showing the value of identifying and categorizing your social audience. You should certainly treat every customer as if they have 10,000 followers, because they just might, but you can also proactively engage with high-value customer and high-value influencers. Getting back to the football analogy, it’s like how teams strive to give every guest a great experience, but they really roll out the red carpet for those season ticket and luxury box holders. Spotlight: I’m not allowed in luxury boxes, so you’ll have to tell me what that’s like. But what is the brand equivalent of rolling out the red carpet? Trip: Leaders are nearly three times more likely than Followers to have a process in place that identifies key social influencers for engagement, and more than twice as likely to identify customer advocates for social outreach. This is the kind of knowledge that gives companies the ability to better target social messaging and promotions like we talked about in our last discussion, as well as a basis for understanding how to measure the impact of their social media programs. I’ll give you an example. I hosted an event at one of my favorite restaurants recently. I had mentioned them in a Tweet several weeks before the event, and on the day of the event, they Tweeted out that they were looking forward to seeing me that evening for the event. It’s a small thing, but it had a big impact and I’d certainly go back as a result. Spotlight: So what specifically can brands use and look at to determine where their potential super-fans are? Trip: Social graph analysis, which looks at both the demographic/psychographic trends as well as the behavioral connections, can surface important brand value. Aberdeen’s PR and Brand Management research indicated that top-performing companies are more than three times more likely than Followers to both determine demographic trends through social listening (44% vs. 13%), and to identify meaningful customer segments through social (44% vs. 12%). This kind of brand-level insight can complement and enrich traditional market research. But perhaps even more importantly, it can serve as an early warning system for customer experience failures. @mikestilesPhoto: freedigitalphotos.net

  • usage of setPropertyListener and setActionListener

    - by Vijay Mohan
    The incorrect usage could lead to hard-to-debug problems so better to understand the fundamentals behind it's working.setpropertyListener queues an event on the server side, so if for a command component you have a showPopup behavior/actionListner as well as setPropertyListener then fwk does the queuing correctly and raises further event on the component. While, the setactionListener simply raises an event on the server side instead of queueing it, so any further event on command component gets cancelled.Also, if you use an ActionListener and showPopup behavior together on a command component, then the order of their invocation is undetermined and also one of event gets cancelled on the component. So, either use only actionListner and do the popup invocation stuff progrmmatically in your bean or use the declarative stuff logically so that no clash of event happens.

  • The Bing Sting - an alternative opinion

    - by Charles Young
    I know I'm a bit of an MS fanboy at times, but please, am I missing something here? Microsoft, with permission of users, exploits clickstream data gathered by observing user behaviour. One use for this data is to improve Bing queries. Google equips twenty of its engineers with laptops and installs the widgets required to provide Microsoft with clickstream data. It then gets their engineers to repeatedly (I assume) type in 'synthetic' queries which bring back 'doctored' hits. It asks its engineers to then click these results (think about this!). So, the behaviour of the engineers is observed and the resulting clickstream data goes off to Microsoft. It is processed and 'improves' Bing results accordingly.   What exactly did Microsoft do wrong here?   Google's so-called 'Bing sting' is clearly a very effective attack from a propaganda perspective, but is poor practice from a company that claims to do no evil. Generating and sending clickstream data deliberately so that you can then subsequently claim that your competitor 'copied' that data from you is neither fair nor reasonable, and suggests to me a degree of desperation in the face of real competition.   Monopolies are undesirable, whether they are Microsoft monopolies or Google monopolies.    Personally, I'm glad Microsoft has technology in place to observe user behaviour (with permission, of course) and improve their search results using such data. I can only assume Google doesn't implement similar capabilities. Sounds to me as if, at least in this respect, Microsoft may offer the better technology.

  • Validate if aTextBox Value Start with a Specific Letter

    - by Vincent Maverick Durano
    In case you will be working on a page that needs to validate the first character of the TextBox entered by a user then here are two options that you can use: Option 1: Using an array   1: <asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server"> 2: <script type="text/javascript"> 3: function CheckFirstChar(o) { 4: var arr = ['A', 'B', 'C', 'D']; 5: if (o.value.length > 0) { 6: for (var i = 0; i < arr.length; i++) { 7: if (o.value.charAt(0) == arr[i]) { 8: alert('Valid'); 9: return true; 10: } 11: else { 12: alert('InValid'); 13: return false; 14: } 15: } 16: } 17: } 18: </script> 19: </asp:Content> 20: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> 21: <asp:TextBox ID="TextBox1" runat="server" onblur="return CheckFirstChar(this);"></asp:TextBox> 22: </asp:Content>   The example above uses an array of string for storing the list of  characters that a TextBox value should start with. We then iterate to the array and compare the first character of TextBox value to see if it matches any characters from the array. Option 2: Using Regular Expression (Preferred way)   1: <asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server"> 2: <script type="text/javascript"> 3: function CheckFirstChar(o) { 4: pattern = /^(A|B|C|D)/; 5: if (!pattern.test(o.value)) { 6: alert('InValid'); 7: return false; 8: } else { 9: alert('Valid'); 10: return true; 11: } 12: } 13: </script> 14: </asp:Content> 15: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> 16: <asp:TextBox ID="TextBox1" runat="server" onblur="return CheckFirstChar(this);"></asp:TextBox> 17: </asp:Content>   The example above uses regular expression with the pattern  /^(A|B|C|D)/. This will check if the TextBox value starts with A,B,C or D. Please note that it's case sensitive. If you want to allow lower case then you can alter the patter to this /^(A|B|C|D)/i. The i in the last part will cause a case-insensitive search.   That's it! I hope someone find this post useful!

  • Wordnik Accelerator

    - by prabhpreet
    Wow, creating IE Accelerators is superbly easy. If you want to learn how to create one, go here (some MSDN blog) and the MSDN documentation (clearly written). I was fed up of dictionary.com bringing all those popups and the stupid definitions of Google's dictionary. So I decided to scratch my own itch. I randomly stumbled on the site called Wordnik and it provides with all examples plus definitions plus lots more for words and its popup-free (as far as I know). So I decided to write and accelerator. Here is the source code (Yes, this is it): <?xml version="1.0" encoding="utf-8"?> <os:openServiceDescription xmlns:os="http://www.microsoft.com/schemas/openservicedescription/1.0"> <os:homepageUrl>http://www.wordnik.com</os:homepageUrl> <os:display> <os:name>View on Wordnik</os:name> <os:description>Looking up words on an awesome word site called Wordnik </os:description> <os:icon>http://www.wordnik.com/favicon.ico</os:icon> </os:display> <os:activity category="Define"> <os:activityAction context="selection"> <os:execute method="get" action="http://www.wordnik.com/words/{selection}" ></os:execute> </os:activityAction> </os:activity> </os:openServiceDescription> That’s it.

  • E-Business Suite : Role of CHUNK_SIZE in Oracle Payroll

    - by Giri Mandalika
    Different batch processes in Oracle Payroll flow have the ability to spawn multiple child processes (or threads) to complete the work in hand. The number of child processes to fork is controlled by the THREADS parameter in APPS.PAY_ACTION_PARAMETERS view. THREADS parameter The default value for THREADS parameter is 1, which is fine for a single-processor system but not optimal for the modern multi-core multi-processor systems. Setting the THREADS parameter to a value equal to or less than the total number of [virtual] processors available on the system may improve the performance of payroll processing. However on the down side, since multiple child processes operate against the same set of payroll tables in HR schema, database may experience undesired consequences such as buffer busy waits and index contention, which results in giving up some of the gains achieved by using multiple child processes/threads to process the work. Couple of other action parameters, CHUNK_SIZE and CHUNK_SHUFFLE, help alleviate the database contention. eg., Set a value for THREADS parameter as shown below. CONNECT APPS/APPS_PASSWORD UPDATE PAY_ACTION_PARAMETERS SET PARAMETER_VALUE = DESIRED_VALUE WHERE PARAMETER_NAME = 'THREADS'; COMMIT; (I am not aware of any maximum value for THREADS parameter) CHUNK_SIZE parameter The size of each commit unit for the batch process is controlled by the CHUNK_SIZE action parameter. In other words, chunking is the act of splitting the assignment actions into commit groups of desired size represented by the CHUNK_SIZE parameter. The default value is 20, and each thread processes one chunk at a time -- which means each child process inserts or processes 20 assignment actions at any time. When multiple threads are configured, each thread picks up a chunk to process, completes the assignment actions and then picks up another chunk. This is repeated until all the chunks are exhausted. It is possible to use different chunk sizes in different batch processes. During the initial phase of processing, CHUNK_SIZE number of assignment actions are inserted into relevant table(s). When multiple child processes are inserting data at the same time into the same set of tables, as explained earlier, database may experience contention. The default value of 20 is mostly optimal in such a case. Experiment with different values for the initial phase by +/-10 for CHUNK_SIZE parameter and observe the performance impact. A larger value may make sense during the main processing phase. Again experimentation is the key in finding the suitable value for your environment. Start with a large value such as 2000 for the chunk size, then increment or decrement the size by 500 at a time until an optimal value is found. eg., Set a value for CHUNK_SIZE parameter as shown below. CONNECT APPS/APPS_PASSWORD UPDATE PAY_ACTION_PARAMETERS SET PARAMETER_VALUE = DESIRED_VALUE WHERE PARAMETER_NAME = 'CHUNK_SIZE'; COMMIT; CHUNK_SIZE action parameter accepts a value that is as low as 1 or as high as 16000. CHUNK SHUFFLE parameter By default, chunks of assignment actions are processed sequentially by all threads - which may not be a good thing especially given that all child processes/threads performing similar actions against the same set of tables almost at the same time. By saying not a good thing, I mean to say that the default behavior leads to contention in the database (in data blocks, for example). It is possible to relieve some of that database contention by randomizing the processing order of chunks of assignment actions. This behavior is controlled by the CHUNK SHUFFLE action parameter. Chunk processing is not randomized unless explicitly configured. eg., Set chunk shuffling as shown below. CONNECT APPS/APPS_PASSWORD UPDATE PAY_ACTION_PARAMETERS SET PARAMETER_VALUE = 'Y' WHERE PARAMETER_NAME = 'CHUNK SHUFFLE'; COMMIT; Finally I recommend checking the following document out for additional details and additional pay action tunable parameters that may speed up the processing of Oracle Payroll.     My Oracle Support Doc ID: 226987.1 Oracle 11i & R12 Human Resources (HRMS) & Benefits (BEN) Tuning & System Health Checks Also experiment with different combinations of parameters and values until the right set of action parameters and values are found for your deployment.

  • A Great Work : ADF Architecture TV

    - by mustafakaya
    I would like to information about Oracle ADF Product Management's great work ; ADF Architecture TV. This channel has various subjects such as before start a new ADF or any software project what will you need or how can you select team member's skills, or how to implement and design an ADF projects etc. When developing with a new technology, one of the challenges for technical staff is to both learn the features of the technology and how to implement them, and also consider the broader concepts of design, engineering and architecture. Many an IT project has come undone because IT staff have been focused on the nitty gritty details of writing software, rather than looking at the "bigger picture" of how it will all go together. Oracle's "ADF Architecture TV" plans to address this issue by focusing on architectural issues and developer guidelines for writing ADF software solutions. The goal, to give ADF developers an understanding of the decisions you need to build a successful ADF application, potential architectural blueprints to choose from when putting the ADF application together, and potential best practices to take back to your development team.  You can click here for ADF Architecture TV.
