Overview:

This paper describes the following problem analysis tools for the IBM WebSphere for z/OS production environment: Svcdump.jar, HeapRoots, 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 paper 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.
