WebSphere Application Server - IBM Support Assistant, Health Center and Memory Analyser Lab

One of my colleagues drew my attention to this lab: -

Java Troubleshooting with ISA 5 using Health Center and Memory Analyzer

What this lab is about

This lab is provided AS-IS, with no formal IBM support.

In this lab you will use IBM Support Assistant 5 Beta (ISA 5) to diagnose JVM issues experienced by a running WebSphere Application Server 8.5.

A badly implemented web application will be used to simulate common problems such as memory leaks, unexpected garbage collection cycles triggered by System.gc(), large application objects and large HTTP session sizes.

The lab demonstrates how ISA 5 facilitates team team-based collaboration, and provides server-level diagnostic tools to carry out analysis. It also describes the data needed to debug the issues, and introduces the Java problem determination tools available as part of the IBM Support Assistant including Health Center, and Memory Analyzer.

The lab also uses the new health management self protecting and self healing features of WebSphere Application Server 8.5 to dynamically monitor and manage servers, helping to preserve service even if something is about to go wrong.


It's something that was run at Impact in 2013.
