Oracle-L: RE: SGA Max size

In 9202, DB_BUBBER_CACHE, SHARED_POOL, LARGE_POOL and JAVA_POOL can be dynamically altered. But in 901, LARGE_POOL and JAVA POOL are static. If MAX SGA is less than 128MB then Oracle will use 4MB granule size to allocate/deallocate memory. For SGA greater than 128M, Oracle granule size is 16MB.

My understanding of SGA is
SGA = x + y + z
where x = (dbblksize*db_blk_buf OR db_cache_Size if 9i) y=shared_pool
z=java pool, log_buffer

If 9i oracle introduced SGA_MAX_SIZE; the sum of x+y+z can be < SGA_MAX_SIZE; if so, which part of x/y/z expands when need arises.

Thanks
