I don't know if I'm just tired or inept, but I know this is a simple issue and I have not been able to whip out a solution just yet. ANy help is appreciated.

I'm trying to convert this script to work in a 9i db that utilizes the parameter db_cache_size instead of db_block_buffers:

SELECT obj object, COUNT(1) buffers, (COUNT(1)/totsize) * 100 pct_cache FROM x$bh, (SELECT value totsize FROM v$parameter WHERE name = 'db_block_buffers')
WHERE tch = 1
OR (tch = 0 AND lru_flag < 8)
GROUP BY obj, totsize
HAVING (COUNT(1)/totsize) * 100 > 5;

I'm thinking divide db_cache_size by db_block_size from v$parameter but the sql syntax has me a bit perplexed. I'm blaming maybe lack of sleep and sticking to it.

Thanks in advance for any assistance.
