Hello everyone,
I have a solaris 5.5.1 production system running on
E450 with latest os patch. It is our oracle server.
In vmstat output, system always takes more than half
of the cpu resource:
% vmstat 5
procs memory page disk
faults cpu
r b w swap free re mf pi po fr de sr f0 s0 s1 s1
in sy cs us sy id
0 0 0 6592136 407328 0 6651 3 0 0 0 0 0 0 1
0 559 11991 627 27 56 17
I also checked the mpstat, there is no io waiting in
"wt" column. The iostat doesn't show any busy disk,
network has no collision at all. Output of ps doens't
indicate any busy user process. I am running out of
ideas now.
Any ideas? Thanks very much!
zhu
