Tc - I haven't played with these parameters, so I can only offer some ideas
based on the documentation, and maybe someone who has tested this will
respond.
It looks like if you set PARALLEL_AUTOMATIC_TUNING and leave the
LARGE_POOL_SIZE unset, then Oracle will calculate the large pool size for
you. Maybe Oracle thinks you have set LARGE_POOL_SIZE too low and it is
providing a higher value. One test you could perform would be to comment
LARGE_POOL_SIZE out and see if you receive the same value.
Now, as to Oracle dynamically reducing the LARGE_POOL_SIZE, I don't see
any hint that this will occur. Have you seen this mentioned somewhere?
