I 've a question about Large pool and parallel_automatic_tuning . I've set large_pool_size to 500K and parallel_automatic_tuning to true (thinking that parallel_auto... parameter will automatically increase the size of large pool if required. I was just checking sizes and utilization of pools ,& was surprised to see the size of large pool swollen upto 4096 MB with some 122K in use. Now my question is that why ain't oracle freeing up free memory.

Will Oracle shrink the large pool back to initial size or not ?

select pool,name,round(sum(bytes)/(1024*1024),1)||' MB' MB from v$sgastat where
pool='large pool';

POOL        NAME                           MB
----------- -------------------------- ----------
large pool  free memory                  4096.3 MB

TIA
Tc
