  • Kicking off the ODI12c Blog Series

    - by Madhu Nair
    Normal 0 false false false EN-US ZH-TW X-NONE MicrosoftInternetExplorer4 It is always exciting to talk about a new release, especially one as significant as the newly released Oracle Data Integrator 12c (ODI12c). Why? Because it is packed with features that addresses many requirements for the user community. If you missed sneak previews at this year's Oracle Open World sessions, do not despair. Because over the coming weeks the ODI12c team of developers and consultants will be sharing their perspective on key features, experiences and best practices for ODI12c right here through a series of blogs. Before diving into feature details in subsequent blogs it helps to understand the overall themes that went into developing ODI12c. Let the Productivity Flow: Let us face it. Designing for developer user experience is always top of mind to any enterprise software. ODI12c addresses this through the introduction of declarative flow based mappings (the topic of our next ODI blog by the way!!). Reusability has been addressed though the introduction of reusable mappings cutting down development times for repeated logics. An enhanced debugger makes life easy for complex granular debugging scenarios. Unique repository IDs now allow you to manage multiple repositories. Performance is Paramount: Another major area of focus for ODI12c is performance. Increased parallelism (like the multiple target table load feature), reduced session overheads and ability to customize loads plans through physical views all empower the user to tune run times for extreme performances. mapping showing multiple target load physical representation allowing users to choose execution options Integrating it all: This release is not just about ODI12c as a standalone product. Closer integration with Oracle GoldenGate now brings Change Data Capture (CDC) capabilities into ODI12c. Oracle Warehouse Builder (OWB) jobs can now be executed and monitored from within ODI12c. And ODI12c is fast becoming the de facto standard for Oracle Applications that need data integration in their solutions. The best example being the latest release of the Oracle BI Applications technology. Even as we bring you in-depth write-ups about the features there are some great previews and resources that are already out there. Like this super entry by beta partner Rittman Mead Consulting and this ODI12c Key Features White Paper. You can download ODI12c here (this post helps). The best though is the upcoming Executive Webcast featuring customers and executives who have seen and conceived the product. Don’t miss it!

  • What good books are out there on program execution models? [on hold]

    - by murungu
    Can anyone out there name a few books that address the topic of program execution models?? I want a book that can answer questions such as... What is the difference between interpreted and compiled languages and what are the performance consequences at runtime?? What is the difference between lazy evaluation, eager evaluation and short circuit evaluation?? Why would one choose to use one evaluation strategy over another?? How do you simulate lazy evaluation in a language that favours eager evaluation??

  • How do you cope with change in open source frameworks that you use for your projects?

    - by Amy
    It may be a personal quirk of mine, but I like keeping code in living projects up to date - including the libraries/frameworks that they use. Part of it is that I believe a web app is more secure if it is fully patched and up to date. Part of it is just a touch of obsessive compulsiveness on my part. Over the past seven months, we have done a major rewrite of our software. We dropped the Xaraya framework, which was slow and essentially dead as a product, and converted to Cake PHP. (We chose Cake because it gave us the chance to do a very rapid rewrite of our software, and enough of a performance boost over Xaraya to make it worth our while.) We implemented unit testing with SimpleTest, and followed all the file and database naming conventions, etc. Cake is now being updated to 2.0. And, there doesn't seem to be a viable migration path for an upgrade. The naming conventions for files have radically changed, and they dropped SimpleTest in favor of PHPUnit. This is pretty much going to force us to stay on the 1.3 branch because, unless there is some sort of conversion tool, it's not going to be possible to update Cake and then gradually improve our legacy code to reap the benefits of the new Cake framework. So, as usual, we are going to end up with an old framework in our Subversion repository and just patch it ourselves as needed. And this is what gets me every time. So many open source products don't make it easy enough to keep projects based on them up to date. When the devs start playing with a new shiny toy, a few critical patches will be done to older branches, but most of their focus is going to be on the new code base. How do you deal with radical changes in the open source projects that you use? And, if you are developing an open source product, do you keep upgrade paths in mind when you develop new versions?

  • How do I account for changed or forgotten tasks in an estimate?

    - by Andrew
    To handle task-level estimates and time reporting, I have been using (roughly) the technique that Steve McConnell describes in Chapter 10 of Software Estimation. Specifically, when the time comes for me to create task-level estimates (right before coding begins on a project), I determine the tasks at a fairly granular level so that, whenever possible, I have no tasks with a single-point, 50%-confidence estimate greater than four hours. That way, the task estimation process helps with constructing the software while helping me not to forget tasks during estimation. I come up with a range of hours possible for each task also, and using the statistical calculations that McConnell describes along with my historical accuracy data, I can generate estimates at other confidence levels when desired. I feel like this method has been working fairly well for me. We are required to put tasks and their estimates into TFS for tracking, so I use the estimates at the percentage of confidence I am told to use. I am unsure, however, what to do when I do forget a task, or I end up needing to do work that does not neatly fall within one of the tasks I estimated. Of course, trying to avoid this situation is best, but how do I account for forgotten/changed tasks? I want to have the best historical data I can to help me with future estimates, but right now, I basically am just calculating whether I made the 50%-confidence estimate and whether I made it inside the ranged estimate. I'll be happy to clarify what I'm asking if needed -- let me know what is unclear.

  • Operations Manager SQL monitoring issue?

    - by merrillaldrich
    We're in the early stages of implementing System Center Operations Manager 2007 R2, and from what I've see so far it looks really good. I am still interested to see the depth of performance counter information that it'll collect and store, but haven't been able to really dig into that just yet. There is one issue I am seeing and I don't know if others have come across this (could not find much online about it either): computing a database file free space alert rule is a little complicated, and it...(read more)

  • What can go wrong with a GLIBC upgrade?

    - by Sevenless
    I recently installed a piece of software that my group needs for a research project starting next September. Turns out the software has a known crash bug when used with glibc 2.12.1. My boss asked if we can upgrade glibc on the server that's supposed to run it. Cue my skeptical silence.... At some point, I got it into my brain that messing with glibc was about as good an idea as messing with a hungry puma; however, I've been unable to determine the source of this belief. So, if I go ahead with this: Am I doing something flagrantly stupid (e.g. I won't fix my problem, I will brick my server, or I will initiate a zombie apocalypse)? What can go wrong? What is likely to go wrong? How do I avoid the answers to 2 and 3?

  • Can storage-spaces drives be moved to a replacement server when there is a failure

    - by Joe C
    I have tried to search here and Google, but cannot find a case explaining this. Storage spaces is similar to software raid. If the server fails due to motherboard or some other issue, can the drives that comprise that storage spaces config be moved to another win2k12 server without restoring from backup? This can be done in linux software raid. If so, does the storage space config have to be re-created prior to the move, or do the drives hold the config so they are essentially plug and play? Thanks.

  • Business Strategy - Google Case Study

    Business strategy defined by SMBTN.com is a term used in business planning that implies a careful selection and application of resources to obtain a competitive advantage in anticipation of future events or trends. In more general terms business strategy is positioning a company so that it has the greatest competitive advantage over others in the markets and industries that they participate in. This process involves making corporate decisions regarding which markets to provide goods and services, pricing, acceptable quality levels, and how to interact with others in the marketplace. The primary objective of business strategy is to create and increase value for all of its shareholders and stakeholders through the creation of customer value. According to InformationWeek.com, Google has a distinctive technology advantage over its competitors like Microsoft, eBay, Amazon, Yahoo. Google utilizes custom high-performance systems which are cost efficient because they can scale to extreme workloads. This hardware allows for a huge cost advantage over its competitors. In addition, InformationWeek.com interviewed Stephen Arnold who stated that Google’s programmers are 50%-100% more productive compared to programmers working for their competitors.  He based this theory on Google’s competitors having to spend up to four times as much just to keep up. In addition to Google’s technological advantage, they also have developed a decentralized management schema where employees report directly to multiple managers and team project leaders. This allows for the responsibility of the technology department to be shared amongst multiple senior level engineers and removes the need for a singular department head to oversee the activities of the department.  This is a unique approach from the standard management style. Typically a department head like a CIO or CTO would oversee the department’s global initiatives and business functionality.  This would then be passed down and administered through middle management and implemented by programmers, business analyst, network administrators and Database administrators. It goes without saying that an IT professional’s responsibilities would be directed by Google’s technological advantage and management strategy.  Simply because they work within the department, and would have to design, develop, and support the high-performance systems and would have to report multiple managers and project leaders on a regular basis. Since Google was established and driven by new and immerging technology, all other departments would be directly impacted by the technology department.  In fact, they would have to cater to the technology department since it is a huge driving for in the success of Google.

  • Is it possible to rent a virtual instance of Windows/XP/Vista/7 in the cloud on pay as you go basis?

    - by Janusz
    I am a software developer and I need to test my software on different OS all the time. I am using free VPC images from IE6 compat kit from Microsoft but they have only limited options of Windows Versions (Win XP SP3 and some restricted version of Vista). I need a service where I could rent a Virtual OS in the cloud and connect via Remote Dektop. Use for couple of hours and then discard all the stuff I have been doing there. I tried using Amazon S3 but they only have Windows Server 2003 Anyone knows of such a service that would offer different XP/Vista/7 versions ?

  • Lendle Connects Kindle Owners for Cross-Country Book Lending

    - by Jason Fitzpatrick
    You can lend books from your Kindle library to other Kindle users but it’s not always easy to find people with books you want. Lendle is a social network for Kindle readers to share books with each other. If you have a Kindle (the physical Kindle or the software on your smartphone or computer) you can easily lend books to other Kindle users. The problem is that there is no good way for you to easily find out what books your friends have. Furthermore your friends simply may not be into books that you’re into. Enter Lendle, a free service that connects Kindle users across the US (currently the Kindle lending program is limited to US customers) so that they can share books with each other. Your real life friends may not be into vampire romance, for example, but plenty of people on Lendle are and would be happy to loan you books. The only requirements for participation in the Lendle system are: Kindle ownership (either the physical or software-based Kindle) as books you’re willing to lend out. In addition to benefiting from other user’s libraries, Lendle also gives users a small credit when they lend a book–credits are redeemable as Amazon.com gift certificates.

  • What program is making this sound and how can I make it stop

    - by DrFredEdison
    Some program is intermittently making this weird "chook ... chick" sound, no more than every 5 minutes, but sometimes hours or days between making it. There seems to be no pattern as to when it happens, but the sound is definitely coming from the speakers, and is always the same, so I'm pretty confident some piece of software I'm running is playing the sound. Today, I managed to record it, and I've posted it here: http://tristanhavelick.com/chook-chick.mp3 Short of closing my programs one by one, and seeing if the sound continues, are there any tricks for tracking down a problem like this? Is there any software that can trace what sounds come from what programs (something like tcpview with waveforms)? I am running windows xp.

  • T-SQL User-Defined Functions: the good, the bad, and the ugly (part 2)

    - by Hugo Kornelis
    In a previous blog post , I demonstrated just how much you can hurt your performance by encapsulating expressions and computations in a user-defined function (UDF). I focused on scalar functions that didn’t include any data access. In this post, I will complete the discussion on scalar UDFs by covering the effect of data access in a scalar UDF. Note that, like the previous post, this all applies to T-SQL user-defined functions only. SQL Server also supports CLR user-defined functions (written in...(read more)

  • Are there videocamera which geotag individual frames?

    - by Grzegorz Adam Hankiewicz
    I'm looking for a way to record live video with the specific requirement of having each frame georeferenced with GPS. Right now I'm using a normal video camera with a PDA+GPS that records the position, but it's difficult to sync both of these plus sometimes I've forgotten to turn the PDA+GPS or it has failed for some reason and all my video has been useless. Using google I found that about two years ago a company named Seero produced such video cameras and software, but apparently the domain doesn't exist any more and I only find references of other pages mentioning it. Does somebody know of any other product? I need to record this video in HD and have some way to export to Google Maps or other GIS software the positions of the frames in a way that I can click on the map and see what was being recorded in the video at that point. The precission of the GPS tracking is good enough as one position per second, intermediate frames of the video stream can be interpolated.

  • What is new in Oracle SOA Suite 11g R1 PS6? by Shanny Anoep

    - by JuergenKress
    Oracle has released a new version 11.1.1.7.0 for their Oracle Fusion Middleware product line. This version includes Patch Set #6 (PS6) for Oracle SOA Suite 11g R1, with a big list of improvements and fixes for each component in that suite. In this post we will highlight some of the interesting updates with regards to troubleshooting, performance, reliability and scalability. Infrastructure/Purging scripts Database growth is a common problem for large-scale Oracle SOA Suite deployments. Oracle already provides multiple purging strategies for the SOA Suite runtime database. This patch set includes two new scripts for purging most of the runtime data: Table Recreation Script (TRS): This script can be used to reclaim as much database space as possible, while still retaining the open instances. It can be used as a corrective action for databases that grew excessively, for example when purging was not performed at all. This should be used as a single corrective action only; the script does not replace the normal purging scripts. Truncate script: Remove all records from the SOA Suite runtime tables without dropping the tables. This script can be used for cloning SOA Suite environments without copying the instance data, or for recreating test scenarios by cleaning all the runtime data. The Oracle SOA Suite Administrator's guide contains a table with the available purging strategies. Diagnostic dumps Using WLST you could already dump diagnostic information about various components of the SOA Suite. This version adds support to retrieve more information on BPEL and Adapters from the command-line. Diagnostic dumps for BPEL New diagnostic dumps are available for BPEL to get information on thread pools, average processing time for BPEL components, and average waiting times for asynchronous instances. This information can be very useful for performance analysis or troubleshooting. With WLST this information can be retrieved from the command-line and included for monitoring or reporting.

  • In agile environment, how is bug tracking and iteration tracking consolidated.

    - by DXM
    This topic stemmed from my other question about management-imposed waterfall-like schedule. From the responses in the other thread, I gathered this much about what is generally advised: Each story should be completed with no bugs. Story is not closed until all bugs have been addressed. No news there and I think we can all agree with this. If at a later date QA (or worse yet a customer) finds a bug, the report goes into a bug tracking database and also becomes a story which should be prioritized just like all other work. Does this sum up general handling of bugs in agile environment? If yes, the part I'm curious about is how do teams handle tracking in two different systems? (unless most teams don't have different systems). I've read a lot of advice (including Joel's blog) on software development in general and specifically on importance of a good bug tracking tool. At the same time when you read books on agile methodology, none of them seem to cover this topic because in "pure" agile, you finish iteration with no bugs. Feels like there's a hole there somewhere. So how do real teams operate? To track iterations you'd use (whiteboard, Rally...), to track bugs you'd use something from another set of products (if you are lucky enough, you might even get stuck with HP Quality Center). Should there be 2 separate systems? If they are separate, do teams spend time creating import/sync functionality between them? What have you done in your company? Is bug tracking software even used? Or do you just go straight to creating a story?
