• How is the Tomcat temp directory location defined?

  - by sdoca

  I am running Tomcat bundled with Liferay5.2.3 and use Eclipse 3.5 (Galileo) as my IDE. I set up my Tomcat server in Eclipse as per this blog entry: http://www.jroller.com/holy/entry/developing_portlets_for_liferay_in. If I start Tomcat via the Eclipse server config, Liferay/Tomcat uses my C:\Documents and Settings\user\Local Settings\Temp\ directory. However, if I start Tomcat directly using the startup.bat script, Liferay/Tomcat uses the Tomcat temp directory. I can't figure out if Eclipse, Liferay or Tomcat is deciding which temp directory to use or how to change it. I would prefer to use the Tomcat temp directory. I have this issue with both the Lifera/Tomcat bundles 5.5 and 6.0 (liferay-portal-tomcat-6.0-5.2.3.zip and liferay-portal-tomcat-5.5-5.2.3.zip). Anybody have any clues?

• connect to mssql from batch script

  - by JPro

  Hi, I am supplying a batch script to create a DSN connection in the user computer before they start to use my application. I am using this in a .bat file. ODBCConf ConfigSysDSN "SQL Server" "DSN=CONNAME|SERVER=PCNAME\INSTANCENAME But I want to make sure they will be able to connect to the database, considering the fact that proper drivers may not be installed in their systems. So, is there any way to check the connection from the same batch file and inform the user if something unable to connect to the database? thanks.

• Podcast Show Notes: By Any Other Name: Governance and Architecture

  - by Bob Rhubart

  The OTN ArchBeat Podcast returns from a brief summer hiatus with a three-part conversation about IT architecture and governance. My guests for this conversation are Eric Stephens , an Oracle Enterprise architect and a frequent guest on this program. Joining Eric on the panel is Tim Hall , Senior Director of product management for the Oracle Enterprise Repository, Oracle Service Registry, and Oracle Application Integration Architecture. Tim made his first appearance on ArchBeat as panelist on the recent program featuring Thomas Erl. The Conversation Listen to Part 1:Why it's important to revive the dormant conversation about IT governance. Listen to Part 2 (Sept 19): Balancing functional, technical, operational requirements to meet the challenge of defining appropriate governance "guardrails." Listen to Part 3 (Sept 26): Bringing IT architecture out of the ivory tower to make governance a less intimidating, more collaborative process. Additional Resources Leveraging Governance to Sustain Enterprise Architecture Efforts, an Oracle white paper by Eric Stephens. SOA, Cloud, and Service Technologies, a transcript of an ArchBeat interview with Thomas Erl, Tim Hall, and Demed L'Her, in which Tim says the following about governance: "For a long time people have argued that SOA governance is sort of an awkward name, no one wanted to be audited. There's 50% of the world that think, yes, we're going to have to tops down initiative to address this and there's 50% of the world that says that it feels like a heavy weight process that I want no part of. So what I think we should do is change the name…"

• Why doesn't Maven's mvn clean ever work the first time?

  - by hoffmandirt

  Nine times out of ten when I run mvn clean on my projects I experience a build error. I have to execute mvn clean multiple times until the build error goes away. Does anyone else experience this? Is there any way to fix this within Maven? If not, how do you get around it? I wrote a bat file that deletes the target folders and that works well, but it's not practical when you are working on multiple projects. I am using Maven 2.2.1.

• latest Xemacs on Windows binary download

  - by anjanb

  I'm trying to get an updated version for Windows vista. I previously got 21.4.22 but it's been a year since that release. The linux versions should be 22.x. I'm wondering if anyone else builds stable binaries for Windows ? 21.4.22 has several bugs and I cannot figure out how to fix them. I know Xemacs is not as active as GNU emacs but still aren't there any Xemacs users on windows who build their own copies even if the official site doesn't ? I would like to be able to compare buffers, files and directories apart from being able to edit any file : java, javascript, ruby, .bat, .sh, .xml, etc.

• Can I get a dump of all my databases *except one* using mysqldump?

  - by Daniel Magliola

  I'm currently using mySQLdump to backup my dev machine and servers. There is one project I just started, however, that has a HUUUUUGE database that I don't really need backed up, and i'll be a big problem to add it to the rest of the backup cycle. I'm currently doing this: "c:\Program Files\mysql\MySQL Server 5.1\bin\mysqldump" -u root -pxxxxxx --all-databases g:\backups\MySQL\mysqlbackup.sql Is it possible to somehow specify "except this database(s)"? I wouldn't like to have to specify the list of DBs manually, since that would mean that I'd have to remember updating my backup batch file every time I create a new DB, and I know that's not gonna happen. EDIT: As you probably guessed from my command line above, i'm doing this on Windows, so I can't do any kind of fancy bash stuff, only wimpy .bat things. Alternatively, if you have other ideas to solve this same issue, they are more than welcome, of course! Thanks Daniel

• How can player actions be "judged morally" in a measurable way?

  - by Sebastien Diot

  While measuring the player "skills" and "effort" is usually easy, adding some "less objective" statistics can give the player supplementary goals, especially in a MUD/RPG context. What I mean is that apart from counting how many orcs were killed, and gems collected, it would be interesting to have something along the line of the traditional Good/Evil, Lawful/Chaotic ranking of paper-based RPG, to add "dimension" to the game. But computers cannot differentiate good/evil effectively (nor can humans in many cases), and if you have a set of "laws" which are precise enough that you can tell exactly when the player breaks them, then it generally makes more sense to actually prevent them from doing that action in the first place. One example could be the creation/destruction axis (if players are at all allowed to create/build things), possibly in the form of the general effect of the player actions on "ecology". So what else is there left that can be effectively measured and would provide a sense of "moral" for the player? The more axis I have to measure, the more goals the player can have, and therefore the longer the game can last. This also gives the players more ways of "differentiating" themselves among hordes of other players of the same "class" and similar "kit".

• Connecting Clinical and Administrative Processes: Oracle SOA Suite for Healthcare Integration

  - by Mala Ramakrishnan

  One of the biggest IT challenges facing today’s health care industry is the difficulty finding reliable, secure, and cost-effective ways to exchange information. Payers and providers need versatile platforms for enterprise-wide information sharing. Clinicians require accurate information to provide quality care to patients while administrators need integrated information for all facets of the business operation. Both sides of the organization must be able to access information from research and development systems, practice management systems, claims systems, financial systems, and many others. Externally, these organizations must share claims data, patient records, pharmaceutical data, lab reports, and diagnostic information among third party entities—all while complying with emerging standards for formatting, processing, and storing electronic health records (EHR). Service-oriented architecture (SOA) enables developers to integrate many types of software applications, databases and computing platforms within a particular health network as well as with community, state, and national health information exchanges. The Oracle SOA Suite for healthcare integration is designed to provide healthcare organizations with comprehensive integration capabilities within a unified middleware platform, as well as with healthcare libraries and templates for streamlining healthcare IT projects. It reduces the need for specialized skills and enforces an enterprise-wide view of critical healthcare data.  Here is a new white paper that details more about this offering: Oracle SOA Suite for Healthcare Integration

• How does a one-man developer do its games' sounds?

  - by Gustavo Maciel

  Before anything, that's not a "oh, where can I find resources?" question. Well, I've been curious about one thing in the indie games industry. For the development of the game, such tasks like game design, art, sketches, code programming and etc can be easily done by just one person. You can just take up a paper and pencil and you're a game designer. You can just take software like Photoshop or Paint and you're an artist, a scanner and you're a sketcher, a compiler and you're a programmer. For sound it's different. You may tell me: Well, follow the line, take a lot of instruments and record it. But all we know that things don't work this way. I can list up some changes for us: External noises are a big problem, sound effects can't be made with instruments, it can't sound like a recorded and clipped sound. Well I can imagine how they do this in large companies, with such big studios and etc. But to summarise, my question is: What's the best way for a one-man indie to do all its sound? Does he have to synthesize everything? Record and buy some crazy program for editing sounds?

• Cruise control.NET invoking an IDE

  - by Maddy

  Hi, I have an IDE named VxWorks 653 2.2.3 Development shell which needed to be invoked all the time when i notice any change in my source files.So i had invoked this shell through a VB scripts which invokes two more .bat(Batch files) to get this shell popped up for execution.Now i feel that since my IDE can be invoked by command line,it can also be invoked through nant scripts using the statement like D:\WindRiver\wrenv.exe -p vxworks653-2.2.3 But what i see is that its not at all invoking.I had tried all different ways but all turned out to be in vain. Can anyone pls suggest me any way either in nant scripts or in cruise control by which my IDE can be invoked.Now at present i am using VB scripts which is a very long proceess.

• IDC's Sally Hudson on Securing Mobile Access

  - by Naresh Persaud

  After the launch of Identity Management 11g R2, Oracle Magazine writer David Baum sat down with Sally Hudson, research director of security products at International Data Corporation (IDC) to get her perspective on securing mobile access.  Below is an excerpt from the interview. The complete article can be found here. "We’re seeing a much more diverse landscape of devices, computing habits, and access methods from outside of the corporate network. This trend necessitates a total security picture with different layers and end-point controls. It used to be just about keeping people out. Now, you have to let people in. Most organizations are looking toward multifaceted authentication—beyond the password—by using biometrics, soft tokens, and so forth to do this securely. Corporate IT strategies have evolved beyond just identity and access management to encompass a layered security approach that extends from the end point to the data center. It involves multiple technologies and touch points and coordination, with different layers of security from the internals of the database to the edge of the network." ( Sally Hudson, Oracle Mag Sept/Oct 2012) As the landscape changes you can find out how to adapt by reading Oracle's strategy paper on providing identity services at Internet scale.

• TCO Comparison: Oracle Exadata vs IBM P-Series

  - by Javier Puerta

  Cost Comparison for Business Decision-makersOracle Exadata Database Machine vs. IBM Power SystemsHow to Weigh a Purchase DecisionOctober 2012 Download full report here In this research-based  white paper conducted at the request of Oracle, The FactPoint Group compares the cost of ownership of the Oracle Exadata engineered system to a traditional build-your-own (BYO) solution, in this case an IBM Power 770 (P770) with SAN storage.  The IBM P770 was chosen given it is IBM’s current most popular model, based on FactPoint primary and secondary research and IBM claims, and because at least one of the interviewed customers had specifically migrated from a P770 to Exadata, affording us a more specific data point for comparison. This research found that Oracle Exadata: Can be deployed more quickly and easily requiring 59% fewer man-hours than a traditional IBM Power Systems solution. Delivers dramatically higher performance typically up to 12X improvement, as described by customers, over their prior solution.  Requires 40% fewer systems administrator hours to maintain and operate annually, including quicker support calls because of less finger-pointing and faster service with a single vendor.  Will become even easier to operate over time as users become more proficient and organize around the benefits of integrated infrastructure. Supplies a highly available, highly scalable and robust solution that results in reserve capacity that make Exadata easier for IT to operate because IT administrators can manage proactively, not reactively.  Overall, Exadata operations and maintenance keep IT administrators from “living on the edge.”  And it’s pre-engineered for long-term growth. Finally, compared to IBM Power Systems hardware, Exadata is a bargain from a total cost of ownership perspective:  Over three years, the IBM hardware running Oracle Database cost 31% more in TCO than Exadata.

• Invoke Java via Batch File with Filepath Arguments

  - by EricIdyll

  Hi there, I'm having an issue getting files loaded into an app called GCS, by dragging them onto the executable. GCS can be invoked on Windows with a bat file, which goes like this: @echo off start javaw -Xmx256M -jar "GURPS Character Sheet.app/Contents/Resources/Java/GCS.jar" %* If I hard code a filepath in place of the batch argument wildcard (with quotes), it works. If I run the debugger with a filepath argument it works. If I echo %, it gives me the correct filename with quotes around it. If I add quotes around % it still breaks. I have a disconnect here between DOS and Java, and I'm at a loss. Does anyone recognize this problem? Thanks in advance.

• Evaluating a Programmer for Startup

  - by HelpJ

  Hi, I have sorted through the previous questions and couldn't find a specific answer to the following (and thank you in advance): I have fully developed my idea on paper and am looking to move forward with it, create it, and grow it. Since I am non-technical, I am looking to either partner or employ (I would pay for his/her services) for a very talented and well-rounded programmer to help create and develop the project. I am looking for someone that can act as a IT manager/CTO and get the job done while I use my resources to develop and deploy the strategy, deal with the business side of things, raise capital, grow, etc. However, due to my lack of IT knowledge, it is always hard for me to differentiate between a good and bad programmer and therefore only find out if he/she is good or not when it is too late. So my question that I have been asking everyone around me is "How do I assess whether the programmer is good or not if I cannot evaluate them myself?" and "Is there any website that reviews and rates programmers?" I have asked many to refer me to talented programmers but all are either not local (important for me to work side by side with them), happily employed or working on their own startup. I have also asked these programmers to help me find others but none seem to be able to help. Any help would be extremely appreciated. Thank you so much, HelpJ

• Data that has been deleted in P6, how is it updated in Analytics

  - by Jeffrey McDaniel

  In P6 Reporting Database 2.0 the ETL process looked to the refrdel table in the P6 PMDB to determine which projects were deleted. The refrdel table could not be cleared out between ETL runs or those deletes would be lost. After the ETL process is run the refrdel can be cleared out. It is important to keep any purging of the refrdel in a consistent cycle so the ETL process can pick up these deletes and process them accordingly.  In P6 Reporting Database 2.2 and higher the Extended Schema is used as the data source. In the Extended Schema, deleted data is filtered out by the views. The Extended Schema services will handle any interaction with the refrdel table, this concern with timing refrdel cleanup and ETL runs is not applicable as of this release. In the Extended Schema tables (ex. TaskX) there can still be deleted data present. The Extended Schema views join on the primary PMDB tables (ex. Task) and filter out any deleted data.  Any data that was deleted that remains in the Extended Schema tables can be cleaned out at a designated time by running the clean up procedure as documented in the P6 Extended Schema white paper. This can be run occasionally but is not necessary to run often unless large amounts of data has been deleted.

• Ray Tracing concers: Efficient Data Structure and Photon Mapping

  - by Grieverheart

  I'm trying to build a simple ray tracer for specific target scenes. An example of such scene can be seen below. I'm concerned as to what accelerating data structure would be most efficient in this case since all objects are touching but on the other hand, the scene is uniform. The objects in my ray tracer are stored as a collection of triangles, thus I also have access to individual triangles. Also, when trying to find the bounding box of the scene, how should infinite planes be handled? Should one instead use the viewing frustum to calculate the bounding box? A few other questions I have are about photon mapping. I've read the original paper by Jensen and many more material. In the compact data structure for the photon they introduce, they store photon power as 4 chars, which from my understanding is 3 chars for color and 1 for flux. But I don't understand how 1 char is enough to store a flux of the order of 1/n, where n is the number of photons (I'm also a bit confused about flux vs power). The other question about photon mapping is, if it would be more efficient in my case to store photons per object (or even per Object's triangle) instead of using a balanced kd-tree. Also, same question about bounding box of the scene but for photon mapping. How should one find a bounding box from the pov of the light when infinite planes are involved?

• Documenting mathematical logic in code

  - by Kiril Raychev

  Sometimes, although not often, I have to include math logic in my code. The concepts used are mostly very simple, but the resulting code is not - a lot of variables with unclear purpose, and some operations with not so obvious intent. I don't mean that the code is unreadable or unmaintainable, just that it's waaaay harder to understand than the actual math problem. I try to comment the parts which are hardest to understand, but there is the same problem as in just coding them - text does not have the expressive power of math. I am looking for a more efficient and easy to understand way of explaining the logic behind some of the complex code, preferably in the code itself. I have considered TeX - writing the documentation and generating it separately from the code. But then I'd have to learn TeX, and the documentation will not be in the code itself. Another thing I thought of is taking a picture of the mathematical notations, equations and diagrams written on paper/whiteboard, and including it in javadoc. Is there a simpler and clearer way? P.S. Giving descriptive names(timeOfFirstEvent instead of t1) to the variables actually makes the code more verbose and even harder too read.

• Antenna Aligner part 2: Finding the right direction

  - by Chris George

  Last time I managed to get "my first app(tm)" built, published and running on my iPhone. This was really cool, a piece of my code running on my very own device. Ok, so I'm easily pleased! The next challenge was actually trying to determine what it was I wanted this app to do, and how to do it. Reverting back to good old paper and pen, I started sketching out designs for the app. I knew I wanted it to get a list of transmitters, then clicking on a transmitter would display a compass type view, with an arrow pointing the right way. I figured there would not be much point in continuing until I know I could do the graphical part of the project, i.e. the rotating compass, so armed with that reasoning (plus the fact I just wanted to get on and code!), I once again dived into visual studio. Using my friend (google) I found some example code for getting the compass data from the phone using the PhoneGap framework. // onSuccess: Get the current heading // function onSuccess(heading) {    alert('Heading: ' + heading); } navigator.compass.getCurrentHeading(onSuccess, onError); Using the ripple mobile emulator this showed that it was successfully getting the compass heading. But it didn't work when uploaded to my phone. It turns out that the examples I had been looking at were for PhoneGap 1.0, and Nomad uses PhoneGap 1.4.1. In 1.4.1, getCurrentHeading provides a compass object to onSuccess, not just a numeric value, so the code now looks like // onSuccess: Get the current magnetic heading // function onSuccess(heading) {    alert('Heading: ' + heading.magneticHeading); }; navigator.compass.getCurrentHeading(onSuccess, onError); So the lesson learnt from this... read the documentation for the version you are actually using! This does, however, lead to compatibility problems with ripple as it only supports 1.0 which is a real pain. I hope that the ripple system is updated sometime soon.
