Hello All,
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.
