yeah this is old. I know its on the web. However, the responses I see are
not to the question I have.
What is the point to having two parameters? If SGA_MAX_SIZE reserves memory
for oracle as an upper bound, but would I want to be able to raise and
lower SGA_TARGET? What do I do with the 'spare memory'.
PGA_AGGREGATE_TARGET is separate and not taken from memory reserved with
SGA_MAX_SIZE
db_cache,shared_pool, large_pool,streams, java, etc... all come out of
SGA_TARGET. So what is the point to this? I am missing something.
I have I have 20 GB SGA_MAX_SIZE and a 10 GB SGA_TARGET. What is oracle
doing with the other 10 GB?
