As you begin to containerize Liberty applications, it's important to keep in mind how running in a container environment can affect performance. Performance tuning a Liberty container begins with tuning the JVM. The standard mechanisms that java uses to understand system resources such as memory...

If you experience production issues with WebSphere Application Server (WAS) traditional, it's often useful to log performance statistics to a file for later analysis. This includes things such as thread pool utilization, application response times, and so on. Running without such monitoring data...
One of the key values of Java is the Just-In-Time (JIT) compiler . This converts the hottest Java methods from interpreted code into native code at runtime. The performance difference is massive: typically, 10-20 times faster (i.e. a magnitude). The JIT is enabled by default, and, in general,...
You have hopefully seen our series of blogs about the Migration Toolkit for Application Binaries (binary scanner) but did you know we also have another tool to help you with your application migrations? The WebSphere Application Migration Toolkit (source scanner) analyzes your application...
So, you’re ready to migrate your application to a new environment, be it Liberty, a newer Java SE version, or a newer version of WebSphere traditional ? However, you aren’t sure what changes you might need to make to your application for it to run. That’s where the analysis report of the ...
So, you've been working on modernizing your WebSphere application. With the help of the WebSphere Application Toolkit for Application Binaries ( Binary Scanner ), you've selected a runtime that supports the technologies you depend on. You've gotten an understanding of what libraries you need and...
The history of SSL/TLS in the enterprise has been a dramatic one over the past decade or so. In 2014, the IT world was rocked by the discovery of a serious security vulnerability called POODLE, affecting what was then the de facto standard for communication encryptions, SSLv3. Information...
Following on from my announcement post last month, I am pleased to report that IBM WebSphere Automation is now generally available! Built on top of the IBM Automation foundation and Red Hat OpenShift, IBM WebSphere Automation helps WebSphere admins and operations teams manage and secure...
For a video presentation of this topic, see the replay of the Customer Advisory Board session . Gauges: Small Airplanes, Large Airplanes and Space Shuttles Fifteen years ago, most administrators had very limited monitoring of their WebSphere Application Server (WAS) environments. Many only...
