To
quote Steve's book, aka "The Bible":
freeabl:
Freeable chunks contain objects that are normally needed for the duration
of a session or call, and are freed thereafter. However, they can
sometimes be freed earlier, either in whole or in part. Freeable chunks
are not available for temporary removal from memory, because they are not
recreatable.
If you
don't have this book, go now, to the bookstore and buy it. Then read it
about 100 times, after which, if you're *really* bright, maybe 20% of it will
have sunk in, at which point you'll know more than you'll ever need about Oracle
internals. ;-) (Personally, I'm probably pushing 15% or
so....;-))

PS If you're not familiar with the book I refer to, it's "Oracle
Internal Services for waits, latches, locks, and memory" by Steve Adams,
published by O'Reilly. Seriously, if you really want to know this stuff,
get that book.

Hi,
I am getting little confussion how the memory is
allocated for
top-level heaps and subheaps in shared
pool.
How can we know what are all the top-level heaps
and subheaps and their hierarchy.
Is it possible to get it from any X$
tables.
Freeable chunks can be flushed out?If yes ,then
why there should be another type as recreatable chunks?
Please explain.
Thanks in advance
Syed
