Java Forum / General / March 2008Heap dump file size vs heap size
Hi, Do you know how heap dump file size is related to heap size itself? I've multiple heap dumps created using jmap on Solaris using Sun JVM 1.5.0_09 and somehow filesize doesn't relate to heap size itself. Disproportions are quite big actually (even 500MB - 1GB) Michal On Mar 25, 10:18 am, Michal Slocinski <michal.slocin...@gmail.com> wrote: > Hi, > [quoted text clipped - 5 lines] > > Michal Look ta java.lang.Runtime class, see what it can give you... Think about how the heap behaves, how gc() is working depending on various settings, this may give you few clues why the heap size may NOT be related to heap dump file size (and do not forget that there is always extra info in the dump file too)...
