I have been working with performance sensitive applications for a long time now. As can be expected most of them have to use the database at one point or the other. So you inevitably end up having a connection pool. Now to make sure that your application is not suffering from waiting on connections you [...]

This post is contributed by Asad Ali – Enablement Services Consultant at dynaTrace. Based on his experience with numerous customers he describes how to optimize the data access layer of applications by “violating” a paradigm that is often referred to as a golden rule for designing applications. Before the advent of the 3-tier architecture, client [...]

This article was contributed from Keith A. Marshall, Lead Developer at Insight North America. Planning ahead has been my approach for the use of the dynaTrace. As much as dynaTrace is there to allow me to triage and investigate production issues at runtime, I believe that there is greater value in using the system as [...]

Stefan Frandl, Test Automation Team Lead at dynaTrace, recently upgrade of our dynaTrace platform from Java 6u23 to Java 6u25.Since this upgrade we are experiencing random crashes in the Hotspot Compilation Thread on Windows. More details on the crash, the submitted bug report and a potential explanation in our dynaTrace Community Article.

Christopher André is an Enablement Service Consultant at dynaTrace and helps our Customers to maximize their value they get out of dynaTrace. The other day, I went to a customer who was experiencing a problem that happens quite frequently: he had a cache that was constantly growing, leading to OutOfMemory Exceptions. Other problems in the [...]

Most articles about Garbage Collection ignore the fact that the Sun Hotspot JVM is not the only game in town. In fact whenever you have to work with either IBM WebSphere or Oracle WebLogic you will run on a different runtime. While the concept of Garbage Collection is the same, the implementation is not and [...]

// When we get engaged with prospects that are interested in our performance management solution we walk them through a Proof of Concept. We let them install dynaTrace on their own prior to the actual POC. During the POC we ask them to exercise typical use cases on their application that show performance problems. We [...]

Memory and Garbage Collection problems are still the most prominent issues in any java application. One of the reasons is that the very nature of Garbage Collection is often misunderstood. This prompted me to write a summary of some of the most frequent and also most obscure memory related issues that I have encountered in [...]

Recently there was a bigger discussion at dynaTrace around the cost of exceptions. When working with customers we very often find a lot of exceptions they are not aware of. After removing these exceptions, the code runs significantly faster than before. This creates the assumption that using exceptions in your code comes with a significant [...]

Memory Leaks are painful – especially when they crash your production servers. But – how does one go about analyzing the leak that only happens in the production environment? Here is a story I was told while on-site with one of our clients. I asked: “Chris, tell me about a recent performance problem and how [...]
