• Oracle Utilities Application Framework V4.2.0.0.0 Released

  - by ACShorten

  The Oracle Utilities Application Framework V4.2.0.0.0 has been released with Oracle Utilities Customer Care And Billing V2.4. This release includes new functionality and updates to existing functionality and will be progressively released across the Oracle Utilities applications. The release is quite substantial with lots of new and exciting changes. The release notes shipped with the product includes a summary of the changes implemented in V4.2.0.0.0. They include the following: Configuration Migration Assistant (CMA) - A new data management capability to allow you to export and import Configuration Data from one environment to another with support for Approval/Rejection of individual changes. Database Connection Tagging - Additional tags have been added to the database connection to allow database administrators, Oracle Enterprise Manager and other Oracle technology the ability to monitor and use individual database connection information. Native Support for Oracle WebLogic - In the past the Oracle Utilities Application Framework used Oracle WebLogic in embedded mode, and now, to support advanced configuration and the ExaLogic platform, we are adding Native Support for Oracle WebLogic as configuration option. Native Web Services Support - In the past the Oracle Utilities Application Framework supplied a servlet to handle Web Services calls and now we offer an alternative to use the native Web Services capability of Oracle WebLogic. This allows for enhanced clustering, a greater level of Web Service standards support, enchanced security options and the ability to use the Web Services management capabilities in Oracle WebLogic to implement higher levels of management including defining additional security rules to control access to individual Web Services. XML Data Type Support - Oracle Utilities Application Framework now allows implementors to define XML Data types used in Oracle in the definition of custom objects to take advantage of XQuery and other XML features. Fuzzy Operator Support - Oracle Utilities Application Framework supports the use of the fuzzy operator in conjunction with Oracle Text to take advantage of the fuzzy searching capabilities within the database. Global Batch View - A new JMX based API has been implemented to allow JSR120 compliant consoles the ability to view batch execution across all threadpools in the Coherence based Named Cache Cluster. Portal Personalization - It is now possible to store the runtime customizations of query zones such as preferred sorting, field order and filters to reuse as personal preferences each time that zone is used. These are just the major changes and there are quite a few more that have been delivered (and more to come in the service packs!!). Over the next few weeks we will be publishing new whitepapers and new entries in this blog outlining new facilities that you want to take advantage of.

• Unit testing in Django

  - by acjohnson55

  I'm really struggling to write effective unit tests for a large Django project. I have reasonably good test coverage, but I've come to realize that the tests I've been writing are definitely integration/acceptance tests, not unit tests at all, and I have critical portions of my application that are not being tested effectively. I want to fix this ASAP. Here's my problem. My schema is deeply relational, and heavily time-oriented, giving my model object high internal coupling and lots of state. Many of my model methods query based on time intervals, and I've got a lot of auto_now_add going on in timestamped fields. So take a method that looks like this for example: def summary(self, startTime=None, endTime=None): # ... logic to assign a proper start and end time # if none was provided, probably using datetime.now() objects = self.related_model_set.manager_method.filter(...) return sum(object.key_method(startTime, endTime) for object in objects) How does one approach testing something like this? Here's where I am so far. It occurs to me that the unit testing objective should be given some mocked behavior by key_method on its arguments, is summary correctly filtering/aggregating to produce a correct result? Mocking datetime.now() is straightforward enough, but how can I mock out the rest of the behavior? I could use fixtures, but I've heard pros and cons of using fixtures for building my data (poor maintainability being a con that hits home for me). I could also setup my data through the ORM, but that can be limiting, because then I have to create related objects as well. And the ORM doesn't let you mess with auto_now_add fields manually. Mocking the ORM is another option, but not only is it tricky to mock deeply nested ORM methods, but the logic in the ORM code gets mocked out of the test, and mocking seems to make the test really dependent on the internals and dependencies of the function-under-test. The toughest nuts to crack seem to be the functions like this, that sit on a few layers of models and lower-level functions and are very dependent on the time, even though these functions may not be super complicated. My overall problem is that no matter how I seem to slice it, my tests are looking way more complex than the functions they are testing.

• What Counts For A DBA: ESP

  - by Louis Davidson

  Now I don’t want to get religious here, and I’m not going to, but what I’m going to describe in this ‘What Counts for a DBA’ installment sometimes feels like magic. Often  I will spend hours thinking about the solution to a design issue or coding problem, working diligently to try to come up with a solution and then finally just give up with the feeling that I’m not even qualified to be a data entry clerk, much less a data architect.  At this point I often take a walk (or sometimes a nap), and then it hits me. I realize that I have the answer just sitting in my brain, ready to implement.  This phenomenon is not limited to walks either; it can happen almost any time after I stop my obsession about a problem. I call this phenomena ESP (or Extra-Sensory Programming.)  Another term for this could be ‘sleeping on it’, and while the idiom tends to mean to let time pass to actively think about a problem, sleeping on a problem also lets you relax and let your brain do the work. I first noticed this back in my college days when I would play video games for hours on end. We would get stuck deep in some dungeon unable to find a way out, playing for days on end until we were beaten down tired. Once we gave up and walked away, the solution would usually be there waiting for one of us before we came back to play the next day.  Sometimes it would be in the form of a dream, and sometimes it would just be that the problem was now easy to solve when we started to play again.  While it worked great for video games, it never occurred when I studied English Literature for hours on end, or even when I worked for the same sort of frustrating hours attempting to solve a homework problem in Calculus.  I believe that the difference was that I was passionate about the video game, and certainly far less so about homework where people used the word “thou” instead of “you” or x to represent a number. This phenomenon occurs somewhat more often in my current work as a professional data programmer, because I am very passionate about SQL and love those aspects of my career choice.  Every day that I get to draw a new data model to solve a customer issue, or write a complex SELECT statement to ferret out the answer to a complex data question, is a great day. I hope it is the same for any reader of this blog.  But, unfortunately, while the day on a whole is great, a heck of a lot of noise is generated in work life. There are the typical project deadlines, along with the requisite project manager sitting on your shoulders shouting slogans to try to make you to go faster: Add in office politics, and the occasional family issues that permeate the mind, and you lose the ability to think deeply about any problem, not to mention occasionally forgetting your own name.  These office realities coupled with a difficult SQL problem staring at you from your widescreen monitor will slowly suck the life force out of your body, making it seem impossible to solve the problem This is when the walk starts; or a nap. Maybe you hide from the madness under your desk like George Costanza hides from Steinbrenner on Seinfeld.  Forget about the problem. Free your mind from the insanity of the problem and your surroundings. Then let your training and education deep in your brain take over and see if it will passively do the rest for you. If you don’t end up with a solution, the worst case scenario is that you have a bit of exercise or rest, and you won’t have heard the phrase “better is the enemy of good enough” even once…which certainly will do your brain some good. Once you stop expecting whipping your brain for information, inspiration may just strike and instead of a humdrum solution you find a solution you hadn’t even considered, almost magically. So, my beloved manager, next time you have an urgent deadline and you come across me taking a nap, creep away quietly because I’m working, doing some extra-sensory programming.

• Boot Problem in Asus EEE PC 1015CX

  - by Sâmrat VikrãmAdityá

  I am a newbie to Linux world, although I have previously worked on Ubuntu 11.04 for daily use (Net Access and simple recordings using Audacity). I am not sure, at what level I stand as a newbie. I bought this Asus Eee PC two days back. The model is Asus 1015CX. See the specs here http://www.flipkart.com/asus-1015cx-blk011w-laptop-2nd-gen-atom-dual-core-1gb-320gb-linux/p/itmd8qu4quzu8srr . I created a live USB to install 12.10. The usb booted fine. When I clicked "Try Ubuntu" option, it showed me a black screen with a cursor blinking. I waited for 15 minutes and had to restart using the power button. On clicking the "Install Ubuntu" button, the install process went seamlessly. [I have a Windows7 installed on one of the partitions]. i installed it alongside previous windows installation. The system was then rebooted for the first time. It showed the GRUB menu and I selected the first option Ubuntu. After showing the splash screen for a second, it began showing various messages on a black screen and then it struck on "Stopping Save kernel state message". I had to force shut the system using power button. Sometimes it just gives a blank screen with a cursor blinking and on pressing power button, some messages stating that acpid is doing something and stopping services pops up and the system shuts down. I tried booting with "nomodeset" and other parameters as directed in solution to previous such problems on forums. Also Ctrl+Alt+F1,F2,F3,F4,F5,F6..F12 is not doing anything for me anywhere. At installation, I checked Login automatically option. On booting into recovery several options comes up. Clicking resume just gives me a blank screen with cursor blinking. on dropping to root shell and remounting filesystem as RW, I am able to supply some command that worked for others. startx -- Several messages comes up with last one stating Fatal error: No screen found sudo service lightdm start -- Gives a blank screen with a cursor blinking lspci | grep VGA -- Shows some Intel Integrated Graphic... something I don't remember I had reconfigured xserver-xorg, lightdm, reinstalled ubuntu-desktop, unity. What should I do..?? Will going back to 11.04 work..?? Or I should leave all hopes of running Ubuntu on my netbook. Please help.

  - by Bob Rhubart

  The results are in... Listed below are the Top 10 most popular items shared via the OTN ArchBeat Facebook Page for the month of September 2012. The Real Architects of Los Angeles - OTN Architect Day - Oct 25 No gossip. No drama. No hair pulling. Just a full day of technical sessions and peer interaction focused on using Oracle technologies in today's cloud and SOA architectures. The event is free, but seating is limited, so register now. Thursday October 25, 2012. 8:00 a.m. – 5:00 p.m. Sofitel Los Angeles, 8555 Beverly Boulevard, Los Angeles, CA 90048. Oracle Fusion Middleware Security: Attaching OWSM policies to JRF-based web services clients "OWSM (Oracle Web Services Manager) is Oracle's recommended method for securing SOAP web services," says Oracle Fusion Middleware A-Team member Andre Correa. "It provides agents that encapsulate the necessary logic to interact with the underlying software stack on both service and client sides. Such agents have their behavior driven by policies. OWSM ships with a bunch of policies that are adequate to most common real world scenarios." His detailed post shows how to make it happen. Oracle 11gR2 RAC on Software Defined Network (SDN) (OpenvSwitch, Floodlight, Beacon) | Gilbert Stan "The SDN [software defined network] idea is to separate the control plane and the data plane in networking and to virtualize networking the same way we have virtualized servers," explains Gil Standen. "This is an idea whose time has come because VMs and vmotion have created all kinds of problems with how to tell networking equipment that a VM has moved and to preserve connectivity to VPN end points, preserve IP, etc." H/T to Oracle ACE Director Tim Hall for the recommendation. Process Oracle OER Events using a simple Web Service | Bob Webster Bob Webster's post "provides an example of a simple web service that processes Oracle Enterprise Repository (OER) Events. The service receives events from OER and utilizes the OER REX API to implement simple OER automations for selected event types." Understanding Oracle BI 11g Security vs Legacy Oracle BI 10g | Christian Screen "After conducting a large amount of Oracle BI 10g to Oracle BI 11g upgrades and after writing the Oracle BI 11g book,"says Oracle ACE Christian Screen, "I still continually get asked one of the most basic questions regarding security in Oracle BI 11g; How does it compare to Oracle BI 10g? The trail of questions typically goes on to what are the differences? And, how do we leverage our current Oracle BI 10g security table schema in Oracle BI 11g?" OIM-OAM-OAAM integration using TAP – Request Flow you must understand!! | Atul Kumar Atul Kumar's post addresses "key points and request flow that you must understand" when integrating three Oracle Identity Management product Oracle Identity Management, Oracle Access Management, and Oracle Adaptive Access Manager. Adding a runtime LOV for a taskflow parameter in WebCenter | Yannick Ongena Oracle ACE Yannick Ongena illustrates how to customize the parameters tab for a taskflow in WebCenter. Tips on Migrating from AquaLogic .NET Accelerator to WebCenter WSRP Producer for .NET | Scott Nelson "It has been a very winding path and this blog entry is intended to share both the lessons learned and relevant approaches that led to those learnings," says Scott Nelson. "Like most journeys of discovery, it was not a direct path, and there are notes to let you know when it is practical to skip a section if you are in a hurry to get from here to there." 15 Lessons from 15 Years as a Software Architect | Ingo Rammer In this presentation from the GOTO Conference in Copenhagen, Ingo Rammer shares 15 tips regarding people, complexity and technology that he learned doing software architecture for 15 years. WebCenter Content (WCC) Trace Sections | ECM Architect ECM Architect Kevin Smith shares a detailed technical post covering WebCenter Content (WCC) Trace Sections.

• Creative, busy Devoxx week

  - by JavaCecilia

  I got back from my first visit to the developer conference Devoxx in Antwerp. I can't describe the vibes of the conference, it was a developer amusement park, hackergartens, fact sessions, comic relief provided by Java Posse, James Bond and endless hallway discussions.All and all - I had a lot of fun, my main mission was to talk about Oracle's main focus for OpenJDK which besides development and bug fixing is making sure the infrastructure is working out for the full community. My focus was not to hang out at night club the Noxx, but that was came included in the package :)The London Java community leaders Ben Evans and Martijn Verburg are leading discussions in the community to lay out the necessary requirements for the infrastructure for build and test in the open. They called a first meeting at JavaOne gathering 25 people, including people from RedHat, IBM and Oracle. The second meeting at Devoxx included 14 participants and had representatives from Oracle and IBM. I hope we really can find a way to collaborate on this, making sure we deliver an efficient infrastructure for all engineers to contribute to OpenJDK with.My home in all of this was the BOF rooms and the sessions there meeting the JUG leaders, talking about OpenJDK infrastructure and celebrating the Duchess Duke Award together with the others. The restaurants in the area was slower than I've ever seen, so I missed out on Trisha Gee's brilliant replay of the workshop "The Problem with Women in IT - an Agile Approach" where she masterly leads the audience (a packed room, 50-50 gender distribution) to solve the problem of including more diversity in the developer community. A tough and sometimes sensitive topic where she manages to keep the discussion objective with a focus of improving the matter from a business perspective. Mattias Karlsson is organizing the Java developer conference Jfokus in Stockholm and was there talking to Andres Almires planning a Hackergarten with a possible inclusion of an OpenJDK bugathon. That would be really cool, especially as the Oracle Stockholm Java development office is just across the water from the Jfokus venue, some of the local JVM engineers will likely attend and assist, even though the bug smashing theme will likely be more starter level build warnings in Swing or langtools than fixing JVM bugs.I was really happy that I managed to catch a seat for the Java Posse live podcast "the Third Presidential Debate" a lot of nerd humor, a lot of beer, a lot of fun :) The new member Chet had a perfect dead pan delivery and now I just have to listen more to the podcasts! Can't get the most perfect joke out of my head, talking about beer "As my father always said: Better a bottle in front of me than a frontal lobotomy" - hilarious :)I attended the sessions delivered by my Stockholm office colleagues Marcus Lagergren (on dynamic languages on the jvm, JavaScript in particular) and Joel Borggrén-Franck (Annotations) and was happy to see the packed room and all the questions raised at the end.There's loads of stuff to write about the event, but just have to pace myself for now. It was a fantastic event, captain Stephan Janssen with crew should be really proud to provide this forum to the developer community!

• Enterprise Integration: Can Companies Afford It?

  - by Ralph Wheaton

  Each year, my company holds a global sales conference where employees and partners from around the world some together to collaborate, share knowledge and ideas and learn about future plans.  As a member of the professional services division, several of us had been asked to make a presentation, an elevator pitch in 3 minutes or less that relates to a success we have worked on or directly relates to our tag (that is, our primary technology focus).  Mine happens to be Enterprise Integration as it relates Business Intelligence.  I found it rather difficult to present that pitch in a short amount of time and had to pare it down.  At any rate, in just a little over 3 minutes, this is the presentation I submitted.  Here is a link to the full presentation video in WMV format.   Many companies today subscribe to a buy versus build mentality in an attempt to drive down costs and improve time to implementation. Sometimes this makes sense, especially as it relates to specialized software or software that performs a small number of tasks extremely well. However, if not carefully considered or planned out, this oftentimes leads to multiple disparate systems with silos of data or multiple versions of the same data. For instance, client data (contact information, addresses, phone numbers, opportunities, sales) stored in your CRM system may not play well with Accounts Receivables. Employee data may be stored across multiple systems such as HR, Time Entry and Payroll. Other data (such as member data) may not originate internally, but be provided by multiple outside sources in multiple formats. And to top it all off, some data may have to be manually entered into multiple systems to keep it all synchronized. When left to grow out of control like this, overall performance is lacking, stability is questionable and maintenance is frequent and costly. Worse yet, in many cases, this topology, this hodgepodge of data creates a reporting nightmare. Decision makers are forced to try to put together pieces of the puzzle attempting to find the information they need, wading through multiple systems to find what they think is the single version of the truth. More often than not, they find they are missing pieces, pieces that may be crucial to growing the business rather than closing the business. across applications. Master data owners are defined to establish single sources of data (such as the CRM system owns client data). Other systems subscribe to the master data and changes are replicated to subscribers as they are made. This can be one way (no changes are allowed on the subscriber systems) or bi-directional. But at all times, the master data owner is current or up to date. And all data, whether internal or external, use the same processes and methods to move data from one place to another, leveraging the same validations, lookups and transformations enterprise wide, eliminating inconsistencies and siloed data. Once implemented, an enterprise integration solution improves performance and stability by reducing the number of moving parts and eliminating inconsistent data. Overall maintenance costs are mitigated by reducing touch points or the number of places that require modification when a business rule is changed or another data element is added. Most importantly, however, now decision makers can easily extract and piece together the information they need to grow their business, improve customer satisfaction and so on. So, in implementing an enterprise integration solution, companies can position themselves for the future, allowing for easy transition to data marts, data warehousing and, ultimately, business intelligence. Along this path, companies can achieve growth in size, intelligence and complexity. Truly, the question is not can companies afford to implement an enterprise integration solution, but can they afford not to.   Ralph Wheaton Microsoft Certified Technology Specialist Microsoft Certified Professional Developer Microsoft VTS-P BizTalk, .Net

• Social Analytics and the Customer

  - by David Dorf

  Many successful retailers put the customer at the center of everything they do, so its important that the customer is modeled correctly across all their systems.  The path to omni-channel starts and ends with the customer so at ARTS, our next big project is focused on ensuring a consistent representation of customers across our transactional data model, datawarehouse model, and XML schemas.  Further, we've started a new whitepaper that describes how Big Data and Social Media Analytics should be leveraged by retailers to add and additional level of customer insight. Let's start by taking a closer look at the meaning of social analytics.  Here's my definition: Social Analytics, in the retail context, describes the analysis of data obtained from social media sources in an effort to better comprehend and interact with the community of consumers.  This discipline seeks to understand what’s being said by the community about brands and products (“monitoring”), as well as understand the behaviors of those in the community (“profiling”).  The results are used to enforce the brand image, improve product decisions, and better focus marketing, all of which lead to increased sales. To help illustrate the facets of social analytics, I drew the diagram below which was originally published by Retail Touchpoints. There are lots of tools on the market that allow retailers to monitor social media for brand and product mentions.  These include analysis of sentiment, reach, share of voice, engagement, etc.  When your brand is mentioned, good or bad, its an opportunity to engage with the customer and possibly lead to a sale.  Because products are not always unique, its much more difficult to monitor product mentions, but detecting product trends early can help a retailer make better merchandising decisions, especially in fashion. Once a retailer understands what's being said, the next step is learn more about who's saying it.  That involves profiling customers beyond simple demographics to understand their motivations.  Much can be learned from patterns, and even more when customers voluntarily share their data.  Knowing that a customer is passionate about, for example, mountain biking allows the retailer to make relevant offers on helmets, ask for opinions on hydration, and help spread marketing messages. Social analytics has many facets that benefit retailers, some of which are easy but many of which are hard.  Its important for the CMO and CIO to work closely together to plan for these capabilities and monitor the maturity of tools on the market.  This is an area that will separate winners from losers.

• What does the `dmesg` error: "composite sync not supported" mean?

  - by M. Tibbits

  Question: I see [ 20.473125] composite sync not supported and several such entries when I run dmesg. What do they mean? Background: I'm trying to debug a problem where my laptop won't suspend. Since acpi seems happy and I can suspend easily from the command line, I've turned to tracking down all boot-up errors/warnings. So I run dmesg | grep not and, amongst other shtuff, I get: 728:[ 17.267120] composite sync not supported 733:[ 18.009061] composite sync not supported 740:[ 18.159289] registered panic notifier 749:[ 18.162500] vga16fb: not registering due to another framebuffer present 757:[ 18.598251] composite sync not supported 776:[ 20.473125] composite sync not supported 777:[ 20.932266] composite sync not supported 778:[ 28.350231] composite sync not supported 779:[ 28.924913] composite sync not supported 780:[ 35.480658] composite sync not supported And the full log for the few lines right around that first appearance (line 728) is listed at the bottom of my post (I'd happily include anything else). Any ideas what could be causing this? I've read several sites: Ubuntuforums #1 IRC Chat #1 One post talks about ??Adobe flash?? causing this error? Some others also suggest that it might be an nvidia related problem, but I've got a Dell Latitude D630 with an integrated Intel graphics -- so nvidia isn't the problem.

• #altnetseattle &ndash; REST Services

  - by GeekAgilistMercenary

  Below are the notes I made in the REST Architecture Session I helped kick off with Andrew. RSS, ATOM, and such needed for better discovery.  i.e. there still is a need for some type of discovery. Difficult is modeling behaviors in a RESTful way.  ??  Invoking some type of state against an object.  For instance in the case of a POST vs. a GET.  The GET is easy, comes back as is, but what about a POST, which often changes some state or something. Challenge is doing multiple workflows with stateful workflows.  How does batch work.  Maybe model the batch as a resource. Frameworks aren’t particularly part of REST, REST is REST.  But point argued that REST is modeled, or part of modeling a state machine of some sort… ? Nothing is 100% reliable w/ REST – comparisons drawn with TCP/IP.  Sufficient probability is made however for the communications, but the idea of a possible failure has to be built into the usage model of REST. Ruby on Rails / RESTfully, and others used.  What were their issues, what do they do.  ATOM feeds, object serialized, using LINQ to XML w/ this.  No state machine libraries. Idempotent areas around REST and single change POST changes are inherent in the architecture. REST – one of the constrained languages is for the interaction w/ the system.  Limiting what can be done on the resources.  - disagreement, there is no agreed upon REST verbs. Sam Ruby – RESTful services.  Expanded the verbs within REST/HTTP pushes you off the web.  Of the existing verbs POST leaves the most up for debate. Robert Reem used Factory to deal with the POST to handle the new state.  The POST identifying what it just did by the return. Different states are put into POST, so that new prospective verbs, without creating verbs for REST/HTTP can be used to advantage without breaking universal clients. Biggest issue with REST services is their lack of state, yet it is also one of their biggest strengths.  What happens is that the client takes up the often onerous task of handling all state, state machines, and other extraneous resource management.  All the GETs, POSTs, DELETEs, INSERTs get all pushed into abstraction.  My 2 cents is that this in a way ends up pushing a huge proprietary burden onto the REST services often removing the point of REST to be simple and to the point. WADL does provide discovery and some state control (sort of?) Statement made, "WADL" isn't needed.  The JSON, XML, or other client side returned data handles this. I then applied the law of 2 feet rule for myself and headed to finish up these notes, post to the Wiki, and figure out what I was going to do next.  For the original Wiki entry check it out here. I will be adding more to this post with a subsequent post.  Please do feel free to post your thoughts and ideas about this, as I am sure everyone in the session will have more for elaboration.

• SSIS - Connect to Oracle on a 64-bit machine (Updated for SSIS 2008 R2)

  - by jorg

  We recently had a few customers where a connection to Oracle on a 64 bit machine was necessary. A quick search on the internet showed that this could be a big problem. I found all kind of blog and forum posts of developers complaining about this. A lot of developers will recognize the following error message: Test connection failed because of an error in initializing provider. Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3.3 or later client software installation. Provider is unable to function until these components are installed. After a lot of searching, trying and debugging I think I found the right way to do it! Problems Because BIDS is a 32 bit application, as well on 32 as on 64 bit machines, it cannot see the 64 bit driver for Oracle. Because of this, connecting to Oracle from BIDS on a 64 bit machine will never work when you install the 64 bit Oracle client. Another problem is the "Microsoft Provider for Oracle", this driver only exists in a 32 bit version and Microsoft has no plans to create a 64 bit one in the near future. The last problem I know of is in the Oracle client itself, it seems that a connection will never work with the instant client, so always use the full client. There are also a lot of problems with the 10G client, one of it is the fact that this driver can't handle the "(x86)" in the path of SQL Server. So using the 10G client is no option! Solution Download the Oracle 11G full client. Install the 32 AND the 64 bit version of the 11G full client (Installation Type: Administrator) and reboot the server afterwards. The 32 bit version is needed for development from BIDS with is 32 bit, the 64 bit version is needed for production with the SQLAgent, which is 64 bit. Configure the Oracle clients (both 32 and 64 bits) by editing  the files tnsnames.ora and sqlnet.ora. Try to do this with an Oracle DBA or, even better, let him/her do this. Use the "Oracle provider for OLE DB" from SSIS, don't use the "Microsoft Provider for Oracle" because a 64 bit version of it does not exist. Schedule your packages with the SQLAgent. Background information Visual Studio (BI Dev Studio)is a 32bit application. SQL Server Management Studio is a 32bit application. dtexecui.exe is a 32bit application. dtexec.exe has both 32bit and 64bit versions. There are x64 and x86 versions of the Oracle provider available. SQLAgent is a 64bit process. My advice to BI consultants is to get an Oracle DBA or professional for the installation and configuration of the 2 full clients (32 and 64 bit). Tell the DBA to download the biggest client available, this way you are sure that they pick the right one ;-) Testing if the clients have been installed and configured in the right way can be done with Windows ODBC Data Source Administrator: Start... Programs... Administrative tools... Data Sources (ODBC) ADITIONAL STEPS FOR SSIS 2008 R2 It seems that, unfortunately, some additional steps are necessary for SQL Server 2008 R2 installations: 1. Open REGEDIT (Start… Run… REGEDIT) on the server and search for the following entry (for the 32 bits driver): HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC\MTxOCI Make sure the following values are entered: 2. Next, search for (for the 64 bits driver): HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\MSDTC\MTxOCI Make sure the same values as above are entered. 3. Reboot your server.

• Why no more macro languages?

  - by Muhammad Alkarouri

  In this answer to a previous question of mine about scripting languages suitability as shells, DigitalRoss identifies the difference between the macro languages and the "parsed typed" languages in terms of string treatment as the main reason that scripting languages are not suitable for shell purposes. Macro languages include nroff and m4 for example. What are the design decisions (or compromises) needed to create a macro programming language? And why are most of the mainstream languages parsed rather than macro? This very similar question (and the accepted answer) covers fairly well why the parsed typed languages, take C for example, suffer from the use of macros. I believe my question here covers different grounds: Macro languages or those working on a textual level are not wholly failures. Arguably, they include bash, Tcl and other shell languages. And they work in a specific niche such as shells as explained in my links above. Even m4 had a fairly long time of success, and some of the web template languages can be regarded as macro languages. It is quite possible that macros and parsed typing do not go well together and that is why macros "break" common languages. In the answer to the linked question, a macro like #define TWO 1+1 would have been covered by the common rules of the language rather than conflicting with those of the host language. And issues like "macros are not typed" and "code doesn't compile" are not relevant in the context of a language designed as untyped and interpreted with little concern for efficiency. The question about the design decisions needed to create a macro language pertain to a hobby project which I am currently working on on designing a new shell. Taking the previous question in context would clarify the difference between adding macros to a parsed language and my objective. I hope the clarification shows that the question linked doesn't cover this question, which is two parts: If I want to create a macro language (for a shell or a web template, for example), what limitations and compromises (and guidelines, if exist) need to be done? (Probably answerable by a link or reference) Why have no macro languages succeed in becoming mainstream except in particular niches? What makes typed languages successful in large programming, while "stringly-typed" languages succeed in shells and one-liner like environments?

• Creating a new naming context in OUD

  - by Sylvain Duloutre

  A naming context (also known as a directory suffix) is a DN that identifies the top entry in a locally held directory hierarchy. A new naming context can be created using ODSM, the OUD gui admin console, as described in http://docs.oracle.com/cd/E29407_01/admin.111200/e22648/server_config.htm#CBDGCJGF It can also be created using the dsconfig command lione as described below: Creation of a new naming context consists in 3 steps: First create a Local Backend Workflow element (myNewDb in this exemple) ,  responsible for the naming context base dn, e.g o=example. dsconfig create-workflow-element \           --set base-dn:o=example \           --set enabled:true \           --type db-local-backend \           --element-name myNewDb \           --hostname <your host> \           --port <admin port> \           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt Second, create a Workflow element (workFlowForMyNewDb in this exemple) associated with the Local Backend Workflow element. WorkFlow elements are used to route LDAP requests to the appropriate database, based on the target base dn. dsconfig create-workflow \           --set base-dn:o=example \           --set enabled:true \           --set workflow-element:myNewDb \           --type generic \           --workflow-name workFlowForMyNewDb \           --hostname <your host name> \           --port <admin port>\           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt Then, the workflow element must be made visible outside of the directory, i.e added to the internal "routing table". This is done by adding the Workflow to the appropriate Network Group. A Network group  is used to classify incoming client connections and route requests to workflows. dsconfig set-network-group-prop \           --group-name network-group \           --add workflow:workFlowForMyNewDb \           --hostname <your hostname> \           --port <admin port>\           --bindDN cn=Directory\ Manager \           --bindPasswordFile ****** \           --no-prompt At that stage, it is possible to import entries to the new naming context o=example.

• Is Java viable for serious game development?

  - by tehtros

  Ever since I was a little kid, my dream has been to develop games. Well, now that I am older, more mature, and have some programming experience, I would like to start. However, I would like to turn this into a career. The problem, is that my language of choice is Java. Now, I am not intending this to be a Java vs. C++ question, but rather, is Java an acceptable language for serious game development, instead of lower level languages like C++. By serious, I mean high quality graphics, and being able to play a game with said high quality graphics, without much lag on decent computers. Also, eventually, possible making it to consoles. I have scoured the internet, but there are not very many resources for Java game development, not nearly as many as C++. In fact, most engines are written in C++. Once, I tried to play a made with jMonkeyEngine. The game was terribly slow, to the point where my computer froze. I had no other Java applications running and nothing too resource intensive. Keep in mind, that my computer can play most modern 3D games with ease. So, I am really serious about game development, is Java still a viable choice? I have tried multiple times to learn C++, but I don't really like the language. I don't really know why, but usually, whenever I try to learn, I can never grasp the topics. Also, my most of my friends know Java, and one is even anti-C++, saying that no one knows how to use it right. Then, he goes to say that "there is no right way to use C++, that it can not be used correctly. The nature of the language prevents good code." Also, if I continue to learn and improve Java now, and it turns out that later I am required to learn C++, will making the switch be difficult? So, in short, can Java be taken serious, for serious game development. This includes heavy graphics, fast game play without lag, and possibly, and easy switch to consoles?

• Sharing configuration settings between Windows Azure roles

  - by theo.spears

  If you are working on a medium-large Windows Azure project it's likely it will involve more than one role, for example separate web and worker roles. Unfortunately although all the windows azure configuration settings are stored in a single cscfg file, there is no way to share configuration settings between multiple roles. This means you have to duplicate common settings like connection strings across all your roles. There is an open Connect issue about this topic, but Microsoft have not said when they will fix it. In the mean time I've put together a dirty dirty hack cunning workaround that creates a fake role containing your shared configuration settings, and copies it to all roles as part of the build process. Here's how you set it up: 1. Download the zip file attached to this post, and unzip it into the folder containing your Azure project (not your solution folder). 2. Edit your csdef and cscfg files to include the placeholder project ServiceDefinition.csdef<?xml version="1.0" encoding="utf-8"?> <ServiceDefinition name="AzureSpendNotifier" http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition%22"http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition"> <WorkerRole name="GLOBAL"> <ConfigurationSettings> <Setting name="ExampleSetting" /> </ConfigurationSettings> </WorkerRole> <WorkerRole name="MyWorker"> <ConfigurationSettings> </ConfigurationSettings> </WorkerRole> <WebRole name="MyWeb"> <Sites> <Site name="Web"> <Bindings> <Binding name="WebEndpoint" endpointName="WebEndpoint" /> </Bindings> </Site> </Sites> <ConfigurationSettings> </ConfigurationSettings> </WebRole> </ServiceDefinition> ServiceConfiguration.cscfg<?xml version="1.0" encoding="utf-8"?> <ServiceConfiguration serviceName="AzureSpendNotifier" xmlns=http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration osFamily="1" osVersion="*"> <Role name="GLOBAL"> <ConfigurationSettings> <Setting name="ExampleSetting" value="Hello World" /> </ConfigurationSettings> <Instances count="1" /> </Role> <Role name="MyWorker"> <Instances count="1" /> <ConfigurationSettings> </ConfigurationSettings> </Role> <Role name="MyWeb"> <Instances count="1" /> <ConfigurationSettings> </ConfigurationSettings> </Role> </ServiceConfiguration> It is important that all your roles contain a ConfigurationSettings entry in both cscfg and csdef files, even if it's empty- otherwise the shared configuration settings will not be inserted. 3. Open your azure deployment (.ccproj) project in notepad, and add the highlighted line below: ... <Import Project="$(CloudExtensionsDir)Microsoft.CloudService.targets" /> <Import Project="globalsettings/globalsettings.targets" /> </Project> It is important you add this below the Microsoft.CloudService.targets import line, as it replaces some of the rules defined in that file. Visual studio will prompt you to reload the project, say yes. At this point you will have a new Azure role called 'GLOBAL' with settings you can edit through the visual studio properties panel as normal. This role will never be deployed, but any settings you add to it will be copied to all your other roles when deployed or tested locally within visual studio.

• PayPal India Problems Continues

  - by Ravish

  Reserve Bank of India has been giving hard time to PayPal and its users in India. RBI had previously blocked PayPal transactions in India a few times, and they made it difficult to withdraw payments by enforcing exports and forex related compliance. Here is yet another bad news for Indian PayPal users. With effect from March 1st, Indian users cannot receive payments of more than $500 in your PayPal account. Moreover, you cannot keep or use any funds in your PayPal account. You can use your PayPal balance to make send money for any goods or services, and must withdraw it to your bank account within 7 days of the receipt. These changes have rendered PayPal almost useless for small business, webmasters and publishers. Most webmasters and publishers rely on PayPal to receive payments from advertisers and clients. It has also made it impossible to buy anything online with PayPal. Sending payments abroad via other channels is already a pain, sending a bank wire requires too many formalities, documentation and time. Moreover, you are even required to deduct TDS on payments you make for any products or services. The restrictions will take effect on March 1st, so you have 30 days to complete any pending transactions you may have. This step by RBI is yet another gimmick by corrupt Indian Government to make life difficult of entrepreneurs, kill innovation, slap more taxes and create more channels to take bribes. Following is the notification from PayPal about this issue: As part of our commitment to provide a high level of customer service, we would like to give you a 30-day advance notice on changes to our user agreement for India. With effect from 1 March 2011, you are required to comply with the requirements set out in the notification of the Reserve Bank of India governing the processing and settlement of export-related receipts facilitated by online payment gateways (“RBI Guidelines”). In order to comply with the RBI Guidelines, our user agreement in India will be amended for the following services as follows: Any balance in and all future payments into your PayPal account may not be used to buy goods or services and must be transferred to your bank account in India within 7 days from the receipt of confirmation from the buyer in respect of the goods or services; and Export-related payments for goods and services into your PayPal account may not exceed US$500 per transaction. We seek your understanding as we continue to employ our best efforts to comply with the RBI Guidelines in a timely manner.

• Framework 4 Features: Login Id Support

  - by Anthony Shorten

  Given that Oracle Utilities Application Framework 4 is available as part of Mobile Work Force Management and other product progressively I am preparing a number of short but sweet blog entries highlighting some of the new functionality that has been implemented. This is the first entry and it is on a new security feature called Login Id. In past releases of the Oracle Utilities Application Framework, the userid used for authentication and authorization was limited to eight (8) characters in length. This mirrored what the market required in the past with LAN userids and even legacy userids being that length. The technology market has since progressed to longer userid lengths. It is very common to hear that email addresses are being used as credentials for production systems. To achieve this in past versions of the Oracle Utilities Application Framework, sites had to introduce a short userid (8 characters in length) as an alias in your preferred security store. You then configured your J2EE Web Application Server to use the alias as credentials. This sometimes was a standard feaure of the security store and/or the J2EE Web Application Server, if you were lucky. If not, some java code has to be written to implement the solution. In Oracle Utilities Application Framework 4 we introduced a new attribute on the user object called Login Id. The Login Id can be up to 256 characters in length and is an alternative to the existing userid stored on the user object. This means the Oracle Utilities Application Framework can support both long and short userids. For backward compatibility we use the Login Id for authentication but the short userid for authorization and auditing. The user object within the Oracle Utilities Application Framework holds the translation. Backward compatibility is always a consideration in any of our designs for future or changed functionality. You will see reference to this fact in the blog entries I will be composing over the next few months. We have also thought about the flexibility in implementing this feature. The Login Id can be the same value of the Userid (the default for backward compatibility) or can be different. Both the Login Id and Userid have to be unique. This avoids sharing of credentials and is also backward compatible. You can manually enter the Login Id or provision it from Oracle Identity Manager (or other tool). If you use the Login Id only, then we will not autogenerate a short userid automatically as the rules for this can vary from site to site. You have a number of options there. Most Identity provisioning tools can generate a short userid at user creation time and this can be used. If you do not use provisioning tools, then you can write a class extension using the SDK to autoegenerate the userid based upon your sites preference. When we designed the feature there were lots of styles of generating userids (random, initial and surname, numbers etc). We could not really see a clear winner in that respect so we just allowed the extension to be inserted in if necessary. Most customers indicated to us that identity provisioning was the preferred way. This is why we released an Oracle Identity Manager integration with the framework. The Login id is case sensitive now which was not supported under userid. The introduction of the Login Id allows the product to offer flexible options when configuring security whilst maintaining backward compatibility.

• Did I lost my RAID again?

  - by BarsMonster

  Hi! A little history: 2 years ago I was really excited to find out that mdadm is so powerful so it even can reshape arrays so you can start with a smaller array and the grow it as you need. I've bought 3x1Tb drives and made RAID-5. It was fine for a year. Then I bought 2x more, and tried to reshape to RAID-6 out of 5 drives, and due to some mess with superblock versions, lost all content. Had to rebuild it from scratch, but 2Tb of data were gone. Yesterday I bought 2 more drives, and this time I had everything: properly built array, UPS. I've disabled write intent map, added 2 new drives as a spare and run a command to grow array to 7-disk. It started working, but speed was ridiculously slow, ~100kb/sec. AFter processing first 37Mb at such an amasing speed, one of old HDDs fails. I properly shutdown PC and disconnected failed drive. After bootup it appeared it recreated intent map as it was still in mdadm config, so I removed it from config and rebooted again. Now all I see is that all mdadm processes deadlocks, and don't do anything. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1937 root 20 0 12992 608 444 D 0 0.1 0:00.00 mdadm 2283 root 20 0 12992 852 704 D 0 0.1 0:00.01 mdadm 2287 root 20 0 0 0 0 D 0 0.0 0:00.01 md0_reshape 2288 root 18 -2 12992 820 676 D 0 0.1 0:00.01 mdadm And all I see in mdstat is: $ cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid6 sdb1[1] sdg1[4] sdf1[7] sde1[6] sdd1[0] sdc1[5] 2929683456 blocks super 1.2 level 6, 1024k chunk, algorithm 2 [7/6] [UU_UUUU] [>....................] reshape = 0.0% (37888/976561152) finish=567604147.2min speed=0K/sec I've already tried mdadm 2.6.7, 3.1.4 and 3.2 - nothing helps. Did I lost my data again? Any suggestions how can I make it work? OS is Ubuntu Server 10.04.2... PS. Needless to say that data is unaccessible - I cannot mount /dev/md0 as save the most valuable data. You can see my disappointment - the very specific thing I was excited about failed twice taking 5Tb of my data with it.
