enable HeapDumpOnOutOfMemoryError in runtime
java, jconsole
Solution
Yes, you have to use the setVMOption with "`HeapDumpOnOutOfMemoryError`" as p0 and "`true`" as p1 parameter according to the Monitoring and Managing Java SE 6 Platform Applications.
Problem
according to http://java.sun.com/javase/6/webnotes/trouble/TSG-VM/html/clopts.html it should be possible to enable -XX:+HeapDumpOnOutOfMemoryError using JConsole in runtime. How? I assume its somewhere under MBeans tab and the com.sun.management -> HotSpotDiagnostic -> Operations -> setVMOptions ?
