Last week, I presented and demonstrated the installation and management of IBM WebSphere Automation on Red Hat OpenShift. The WebSphere Automation Operator installs and sets up the prerequisites and numerous microservices for the Secure and Health components of WebSphere Automation. The Operator...
As discussed in a past blog post , if you're experiencing performance problems, the first thing to check is whether your garbage collection (GC) is healthy. If the proportion of time in garbage collection is greater than ~10%, then garbage collection is likely unhealthy and the application is...
In our previous blog post , we discussed the value of running the Linux perf native CPU sampling profiler to investigate Java CPU usage in production. However, perf generally requires root access and OpenShift application containers generally don't run with such privileged access. This...
Java SE 17 was released this past September, and this is an important Java release due to its status as a Long-Term-Support release. Support for Java SE 17 migrations has just been introduced in the 21.0.0.4 release of the WebSphere Application Migration Toolkit, and now our tools now allow you...
If your Java workload is experiencing high CPU in production, the basic workflow is generally the following. This article will quickly review the first three steps and then we'll focus on the fourth step in green: Review a native sampling profiler. Garbage Collection The first thing to...
The Community Festival is still going strong, and there have already been some fantastic sessions by IBM Experts and Champions. I hope you've had a chance to enjoy some of the sessions this week. If not ... they're all recorded, so you can catch the recordings. And there are lots more coming...
In previous blog posts we explored optimizations for running Liberty in containers. Part 1 covered optimizations for the JVM and Part 2 covered Liberty containers basics. In this post, we will cover deployment options and performance optimizations for Liberty containers in Kubernetes...
In the previous " Lessons from the field " post we covered performance optimizations for Java running in containers. Joe McClure added some additional Liberty container performance optimizations in his blog post here . In this post, we will cover some more general tips on using Liberty in...
This week's "App Transformers: More than Meets the Eye" Expert TV episode was really informative. @GIL RODRIGUEZ , @John Alcorn and I explored operational concepts across the different deployment environments that our applications participate in while modernizing. We walked through the...
The WebSphere Application Server Migration Tools can be used to analyze the contents of an application and determine what changes are needed to migrate to Liberty, a new version of WebSphere, or a new version of Java. In this post we will explore the new features in the 21.0.0.3 release. ...
