Hi Greg, But what about below SQL> show parameter k_cache_size NAME TYPE VALUE ------------------------------------ ----------- ----- db_16k_cache_size big integer 0 db_2k_cache_size big integer 0 db_32k_cache_size big integer 0 << db_4k_cache_size big integer 0 db_8k_cache_size big integer 0 appearantly db_32k_cache_size is an allowed value. more importantly: oracle database should never crash because of this request to add a 32K buffer cache. It should say: sorry pal, I can't support this request for a 32k buffer cache. No, instead it crashes and we have to pick up the pieces. My tests were on EL5 32-bit.
