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

Well, a heap is just a bunch of memory (allocated
incontiguous extents) and you can practically allocate any size of chunk
of memory from it (with some restrictions). A regular heap has freelist and LRU
list mechanismsfor managing space init as well as memory
allocation/releasing routines

I won't argue that, Allan. The guy writes two sentences, and it
takes a week for the full implications of what he said to sink in.

Oracle performance problems,
