Java Memory, Getting Rid Of The Garbage

 

Java garbage collection is something that you always need to be thinking about. Did you know that enlarging the Java heap size can decrease your performance? Or that an out of memory message isn’t always helped by increasing the heap size? That Java can have memory leaks? There is a lot more to Java garbage collection than you might think. With our special guest Albert Witteveen will examine the issues surrounding Java garbage collection and what you can do to solve some of these issues.

In this webinar Albert will discuss a number of factors including:

  • Introducing Java
  • Java Virtual Machine
  • Collecting Garbage
  • The Different Collectors
  • Monitoring
  • Collection logging – what to look for
  • Tuning

One of the cool features of Java is that the developers don’t have to clear the memory of no longer used items. This does make it easier and most of all, less prone to memory leaks. It does however shift the burden of tuning and watching what the memory does to both performance testers and anyone maintaining a Java implementation. That also means we can as testers for once do more than report, we can actually often fix and improve performance, which is why learning about the way Java handles memory can be gratifying.

Albert will analyse and explain the way Java handles memory, how to properly monitor and analyse the behaviour, common pitfalls and ways to improve performance, robustness and prevent and solve issues.

To watch this webinar and learn from Albert you do need much experience in Java, as long as your not afraid for a bit of tech talk this webinar should help you understand the basics and get you started in properly assessing Java’s memory. You will learn why garbage collection in Java is a lot more important than you might think.

Albert Witteveen (Pluton IT, The Netherlands)

Albert Witteveen has been working both as an operations manager and a professional tester for nearly two decades now. The combination of setting up complex server environments and professional testing almost automatically led to a specialisation in performance testing. He wrote a practical guide to load and stress testing which is available at Amazon. This books discusses how to do performance testing, how to provide real value and how to assess the performance in an objective way. It describes how to perform the tests, what and how to monitor, how to design the tests, how to setup the team and how to report. As a test manager he employs the lessons learned in operations to make testing, more efficient as well as more effective.
