• OSB, Service Callouts and OQL - Part 1

  - by Sabha

  Oracle Fusion Middleware customers use Oracle Service Bus (OSB) for virtualizing Service endpoints and implementing stateless service orchestrations. Behind the performance and speed of OSB, there are a couple of key design implementations that can affect application performance and behavior under heavy load. One of the heavily used feature in OSB is the Service Callout pipeline action for message enrichment and invoking multiple services as part of one single orchestration. Overuse of this feature, without understanding its internal implementation, can lead to serious problems. This post will delve into OSB internals, the problem associated with usage of Service Callout under high loads, diagnosing it via thread dump and heap dump analysis using tools like ThreadLogic and OQL (Object Query Language) and resolving it. The first section in the series will mainly cover the threading model used internally by OSB for implementing Route Vs. Service Callouts. Please refer to the blog post for more details.

• How to edit files in a terminal with vim?

  - by andrew.46

  It is not always possible to edit and create files in a terminal and I would like to get the answers to the basics of manipulating files in a terminal using vim under Ubuntu Linux. Specific questions I have are: How can I open text files for editing? How can I save the file? How can I save the file with a different name? How can I leave the file without saving the changes? What settings are best in my configuration file and where is this file? How do I set the colors for vim? How do I show line numbers in vim and can this be toggled? A lot of questions here but I believe these questions and their answers should cover basic vim usage...

• How can I enable audio system on Envy 15t-3200

  - by Dean Howell

  I just received my HP Envy 15 (June 2012 model) and I cannot get my audio system to fully function. This laptop has 6 speakers. 1.) 2 speakers on the front of the laptop (Stereo). 2.) 2 speakers above the keyboard, just before the LCD hinges. 3.) 2 Subwoofer speakers underneath the battery cover facing downward. Only the 2 speakers in the front are working. This is a "Beats" audio system. There have been many beats audio laptops before this one, so maybe if someone has experience with those, it might translate to this device.

• SSIS 2008 Configuration Settings Handling Logic for Variables Visualized

  - by Compudicted

  There are many articles discussing the specifics of how the configuration settings are applied including the differences between SSIS 2005 and 2008 version implementations, however this topic keeps resurfacing on MSDN’s SSIS Forum. I thought it could be useful to cover the logic aspect visually. Below is a diagram explaining the basic flow of a variable setting for a case when no parent package is involved.   As you can see the run time stage ignores any command line flags for variables already set in the config file, I realize this is not stressed enough in many publications. Besides, another interesting fact is that the command line dtexec tool is case sensitive for the portion following the package keyword, I mean if you specify your flag to set a new value for a variable like dtexec /f Package.dtsx -set \package.variables[varPkgMyDate].value;02/01/2011 (notice the lover case v in .value) You will get errors. By capitalizing the keyword the package runs successfully.

• On Golf Tournaments & Installers

  - by Geertjan

  I've been in touch recently with Ann Maybury, who is creating a golf tournament roundrobin manager for senior citizens in Palm Desert, California. The application is created on the NetBeans Platform and looks as follows, very neat and professional: Ann has been working on wrapping up the application for distribution and needs to include the JRE, since end users of the application don't necessarily have the JRE installed when they install the application. Several blogs and articles are available for creating and customizing installers for NetBeans Platform applications, as well as for bundling the JRE and other resources, though there are some gaps and inccuracies in those documents. However, now there's a new official tutorial, for the first time: http://platform.netbeans.org/tutorials/nbm-nbi.html The above is focused on Ant builds and Windows, specifically, and doesn't cover Maven scenarios, for which there'll be a separate tutorial soon. Feedback on the above new tutorial is very welcome, as always.

• Building a Java CMS - What Existing Product Should I Use?

  - by walnutmon

  I'm a Java developer and in need of a CMS. I've spent a lot of time reading about, and tinkering with Liferay but am concerned that it doesn't cover two of my three major concerns I need to have many sites with individual domains HTML/CSS designers need to be able to design the website templates, look and feel, and layouts in their own tools without having to worry about writing scripts Site and page building APIs must be understandable so that a custom builder interface can be created and harness the CMS as opposed to hacking it Liferay nails the first bullet point, but the second two appear to be unsolved. Does anyone have experience with a Java CMS that does all three? Or have any idea how to approach the problem if none exists? Has someone has used a Java CMS and has been able to add this functionality give some insight?

• Dynamically rewrite URLs upon the user's selection - is it possible?

  - by jitzo

  In my PHP based web application, there's a form that generates a URL according to the user's selection. The form has 7 different fields, each one of them affects the final URL, none of them is mandatory. The final URL can be: /field1/user_setting_of_field1/field3/user_setting_of_field3/field6/user_setting_of_field6/ or just: /field4/user_setting_of_field4 these URLs should be rewritten to- /results.php?field1=user_setting_of_field1&field3=user_setting_of_field3&field6=user_setting_of_field6 and: /results.php?field4=user_setting_of_field4 Is it possible to create a single rewrite rule that will cover these variations? I'd hate to create different rewrite rule for every possible scenario, it'll take forever... I'm currently developing the app on a Windows machine with IIS 7.5, but will eventually deploy it to an Apache server. Is it possible in both? I currently need to solve it for the IIS environment, and later on for Apache.

• Channelling an explosion along a narrow passage

  - by finnw

  I am simulating explosions in a 2D maze game. If an explosion occurs in an open area, it covers a circular region (this is the easy bit.) However if an explosion occurs in a narrow passage (i.e narrower than the blast range) then it should be "compressed", so that it goes further and also it should go around corners. Ultimately, unless it is completely boxed-in, then it should cover a constant number of pixels, spreading in whatever direction is necessary to reach this total area. I have tried using a shortest-path algorithm to pick the nearest N pixels to the origin avoiding walls, but the effect is exaggerated - the blast travels around corners too easily, making U-turns even when there is a clear path in another direction. I don't know whether this is realistic or not but it is counter-intuitive to players who assume that they can hide around a corner and the blast will take the path of least resistance in a different direction. Is there a well-known (and fast) algorithm for this?

• What tools should I consider if my aim is to make a game available to as many platforms as possible?

  - by Kensai

  We're planning on developing a 2D, grid-based puzzle game, and although it's still very early in the planning stages, we'd like to make our decisions well from the beginning. Our strategy will be to make the game available to as many platforms as possible, for example PCs (Windows, Mac and/or Linux), mobile phones (iPhone and/or Android based phones), game consoles (XBLA and/or PSN) PC will have an emphasis, but I believe that's the most flexible platform so that shouldn't be a problem. So, what programming language, game engine, frameworks and all around tools would be best suited for our goal? P.S.: I'm betting a set of tools won't cover ALL of them, and that there will still be some kind of "translating" effort for some platforms, but we'd like to know what the most far reaching are.
