I'having performance problems. And I think is data contention. This is
OLTP system. Solaris 8, Oracle 8.1.7.0
I ran this query:
SELECT count, file#, name FROM x$kcbfwait, v$datafile
WHERE indx + 1 = file# ORDER BY count desc
And this is the top line
13672 1 system01.dbf
By the other side I ran
select * from v$waitstat order by count desc, and the top line show me:
data block 16977 40
How can identified which is the hot segment?
And v$session_wait show me:
event p1 p2 p3
queue messages 7403 15235490980 2147483647
Any help?
Thanks a lot.
Saludos, Ricardo.
