New feature: The Java virtual machine (JVM) is capable of producing Java dump and core files to aid
in troubleshooting. You can use heap dump and system dump files to
help you diagnose memory-related problems, such as memory leaks. You
can use Java core files to help
you diagnose problems where the CPU is persistently 100% busy, when
threads are hanging, or where threads are in a deadlock.

Avoid trouble: The process of generating
dump and core files can have a noticeable performance impact on your
system that can last for many seconds or minutes. If necessary, use
your test and development environments to better understand the impact
of generating dump and core files.
gotcha
Supported configurations: Generating a heap dump or a system dump is not supported
for a non-IBM JVM. If you attempt to generate a heap dump or a system
dump using the administrative console against a non-IBM JVM, the following
message is displayed in the administrative console: oror
