RE: db_file_multiblock_read_count causing full scans to takelonger?

Do you have sga_target set? If so, then db_cache_size is just a minimum. What are the results if you run this instead:

SELECT LEAST(dcs/(ses*dbs), 1048576/dbs) "CALC", dfmbrc FROM (

	SELECT b.value "SES", c.value "DBS", d.value "DFMBRC"
	FROM v$parameter a, v$parameter b, v$parameter c, v$parameter d
	WHERE a.name = 'db_cache_size'
		AND b.name = 'sessions'
		AND c.name = 'db_block_size'
		AND d.name = 'db_file_multiblock_read_count'),
	(SELECT bytes "DCS" from v$sgastat where name = 'buffer_cache');

Thanks,
Brandon
