list, (AIX, 7.3.2)
i have found another abnomality which my db is suddenly showing..
when doing a count(*) on a million row table.... the session is
waiting on "free buffer waits" !! i have 80M db buffers and most of them are
empty/free !!
all the free buffer waits are on one of the db file belonging to the table i
am reading.
i'm runniing 4 dbwr's, and have async io set to false.
again... most of the buffers are FREE
select decode(state,0,'free',1,'Xclusive',2,'Shared',3,'Consistent
read',4,'disk read','other') STATE,
count(*)
from sys.x$bh
group by state
