  • SQL vs. Oracle Live Debate (AKA Smackdown!)

    - by Peter W. DeBetta
    A few years ago I was speaking at a conference in Raleigh, NC where Ted Neward and I found a fun way to promote a Java vs. .NET debate that was planned one evening. We stood in the middle of a crowd during one of the breaks and starting “arguing” about Java vs. .NET with one another. Our voice levels quickly raised and we ended it by slapping each other across the face with a glove to request a challenge. It was a great way to segue to our announcing of the actual debate planned later that evening....(read more)

  • Measuring performance indicators on a cluster

    - by Aditya Singh
    My architecture is based on Amazon. A ELB load balancer balances POST requests among m1.large instances. Every instance has a nginx server on port 80 which distributes the requests to 4 python-tornado servers on backend which handle the request. These tornado servers are taking about 5 - 10ms to respond to one request but this is the internal compute time of every request. I want to put this thing on test and i want to measure the response time from ELB to upstream and back and how does it vary when the QPS throughput is increased and plot a graph of Time vs. QPS vs. Latency and other factors like CPU and Memory. Is there a software to do that or should i log everything somewhere with latency checks and then analyze the whole log to get the stuff out. I would also need to write a self-monitor which keeps checking the whole response time. Is it possible to do it with a script from within the server. If so, will it be accurate ?

  • cluster of services and restarting on package upgrade

    - by Marcin Cylke
    I'm using puppet to manage a bunch of servers. Those servers run a simple service - exposed to the world via load balancer. That service's instances are independent in that they can run on their own, are are deployed on multiple servers to increase responsiveness. Now, when I push a new package to repo and puppet catches up with it appearing there it just updates this package on all services. This results in a short downtime of entire service. Is there a way of configuring puppet to do restart the services sequentially? Or using any other kind of strategy?

  • Anticipating JavaOne 2012 – Number 17!

    - by Janice J. Heiss
    As I write this, JavaOne 2012 (September 30-October 4 in San Francisco, CA) is just over a week away -- the seventeenth JavaOne! I’ll resist the impulse to travel in memory back to the early days of JavaOne. But I will say that JavaOne is a little like your birthday or New Year’s in that it invites reflection, evaluation, and comparison. It’s a time when we take the temperature of Java and assess the world of information technology generally. At JavaOne, insight and information flow amongst Java developers like no other time of the year.This year, the status of Java seems more secure in the eyes of most Java developers who agree that Oracle is doing an acceptable job of stewarding the platform, and while the story is still in progress, few doubt that Oracle is engaging strongly with the Java community and wants to see Java thrive. From my perspective, the biggest news about Java is the growth of some 250 alternative languages for the JVM – from Groovy to Jython to JRuby to Scala to Clojure and on and on – offering both new opportunities and challenges. The JVM has proven itself to be unusually flexible, resulting in an embarrassment of riches in which, more and more, developers are challenged to find ways to optimally mix together several different languages on projects.    To the matter at hand -- I can say with confidence that Oracle is working hard to make each JavaOne better than the last – more interesting, more stimulating, more networking, and more fun! A great deal of thought and attention is being devoted to the task. To free up time for the 475 technical sessions/Birds of feather/Hands-on-Labs slots, the Java Strategy, Partner, and Technical keynotes will be held on Sunday September 30, beginning at 4:00 p.m.   Let’s not forget Java Embedded@JavaOne which is being held Wednesday, Oct. 3rd and Thursday, Oct. 4th at the Hotel Nikko. It will provide business decision makers, technical leaders, and ecosystem partners important information about Java Embedded technologies and new business opportunities.   This year's JavaOne theme is “Make the Future Java”. So come to JavaOne and make your future better by:--Choosing from 475 sessions given by the experts to improve your working knowledge and coding expertise --Networking with fellow developers in both casual and formal settings--Enjoying world-class entertainment--Delighting in one of the world’s great cities (my home town) Hope to see you there!
