keep pool

[AK]

Hi List , I have a 8.1.6 db running on hp-ux 2 cpu . currently it has default db block lru latches  ( i guess this should be 1 since oracle sets it to cpu/2 ) . Now I want to configure keep pool . Which will requires at least 1 lru latches . So I need to specify db block lru latches > 1 ( rite ? ) . Now my question is what should be a good value for db block lru latches and keep pool lru lactes . I have 50000 blocks for db buffers (8K) in total , out of which i am initiallly planning to take 8000 for keep pool . what other consideration i should keep in mind before i set keep pool .   -thanks ak
