Re: Performance issue after creating higher block size tablespace

The db_cache_size is set to 8192 and db_8k_cache_size is also set to 8192.


If that's really the case (and you didn't forget M of then your buffer cache
is tiny, even after the rounding up described in the docs (
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14237/initparams043.htm
):
"The value must be at least 4M * number of cpus * granule size (smaller
values are automatically rounded up to this value)"

I'd seriously think of setting a bigger size.
