Heap Dump using -XX:+HeapDumpOnCtrlBreak
By Poonam-Oracle on Dec 04, 2007
Heap Dumps are useful for Java Object Heap analysis. HeapDumpOnCtrlBreak jvm option would be available in upcoming 5.0 and 1.4.2 update releases that can be used to dump heap when a SIGQUIT signal is sent to the running process. One more feature would be available - if this option is used along with -XX:+PrintClassHistogram then both these tasks will be performed in one single VM Operation so that the Class Histogram and the Heap Dump represent the same snapshot of the process.
