Hi Jurijs, thanks,
 my default block size is 8K
If have a table in a 2k tablespace with the flag to be cached in the keep
pool.
How it is cached?
It takes 8K???? in the keep cache
Could you please give more information :)

Those are hidden! Try:
__DB_2K_KEEP_CACHE_SIZE
__DB_2K_RECYCLE_CACHE_SIZE
 
Just joken ;)
There no K/R/D for diferent block sizes. Just one cache per block size ;)

Hi list I'm investigating this,
if your default blocksize is 8k, and you create a tables using 2k block
you have the
ALTER SYSTEM SET DB_2K_CACHE_SIZE = 100M;
to set the size for this block cache
 
But how do you set the keep and recycle size for this block size
There are none of this parameter.
ALTER SYSTEM SET DB_2K_KEEP_CACHE_SIZE = 1M;
ALTER SYSTEM SET DB_2K_RECYCLE_CACHE_SIZE = 1M;
 
Thank you
