Brain was clearly not engaged when I wrote the
last answer - I have a set of results I produced
some time back when calibrating init.ora parameters
with memory usage. (Out of date by now since it
was 8.0).
Simple test:
Double the size of sessions in the init.ora,
various entries in v$sgastat will increase in
size, even though you haven't changed
shared_pool_size. The shared_pool_size
is just one component of the "shared pool".
