This IBM Redpaper describes problem analysis tools for the WebSphere for z/OS production environment:
- Dumpviewer GUI and jformat
To analyze heap-related issues such as OutOfMemoryError and other crashes, as well as hangs or loops within WebSphere address spaces with a level of degree similar to that of older deployment environments such as CICS and IMS, use the relatively low impact tool of unformatted dumps and Java virtual machine (JVM) internal information.
This Redpaper goes into great detail about the switched virtual circuit (SVC) Analyzer, explaining what svcdump.jar is, where to get it and when and how to use its utilities. Finally, we list several samples for different parameter settings.
The HeapRoots utility and the DumpViewer GUI are mentioned for further information.
