Interactive Diagnostic Data Explorer
Interactive Diagnostic Data Explorer (IDDE) is the strategic tool for allowing interactive analysis of JVM problems using post mortem artifacts such as core files or javacores. It is lightweight, allowing you to quickly get information from the artifact you are investigating where you aren't sure what the problem is and you want to avoid launching resource intensive analysis.

Garbage Collection and Memory Visualizer
The Garbage Collection and Memory Visualizer (GCMV) helps visualise the memory footprint, garbage collection behaviour and performance of Java and Node.js applications using verbose garbage collection output. The Garbage Collection and Memory Visualizer provides recommendations for tuning the application.

Getting Hands On with the IBM Monitoring and Diagnostic Tools for Java
A problem solving 'Troubleshooting Masterclass' that uses the IBM Monitoring and Diagnostic Tools for Java to debug a faulty application running in WebSphere Application Server.
We have comprehensive IBM Diagnostics Guides relating to IBM's Developer Kits. We have now added a paper describing how to maximize IBM Java memory address space under a 32-bit Windows system, and a Garbage Collection and Storage Allocation Techniques paper that might prove helpful in tuning performance.
IBM developer kits
The IBM Centre for Java Technology Development provides Developer Kits for creating and testing Java 2 Platform, Standard Edition applets and applications on some of IBM's most popular platforms.
