Is PermGen on the heap?

843829Mar 17 2006 — edited Apr 11 2006

Hi,

Is PermGen memory space a part of the heap? I read in the GC performance tuning docs [1] that:

The different parts of the heap (permanent generation, tenured generation, and young generation) can grow to the limit of the virtual space as needed.

but I notice in jconsole that the total memory doesn't seem to include this space. It's also under the 'non-heap' section.

Thanks,

Roger
