I am monitoring performance for Sun-Solaris 2.6/2.7/2.8 for
CPU,memory,kernel,etc.
Now there is a Solaris 2.6 box ,it is a Ultra Enterprise 6500 and it gives
some
weird results when I run the command lockstat sleep 5.
I am attaching a txt file which has all details.Well some info regarding the
versions
we have are
Hardware Platform:Ultra Enterprise 6500
OS version: SunOS 5.6 Generic_105181-33 sun 4u
Vxfs version : 3.3.2
I went through a lot of docementation for lock contention,but really not
able to
understand what is the problem.Well give me some technical doc or web sites
where it expalins what exactly has to be done ie any tunable kernel
parameters,any
patches to be installed.I would appreciate if you can reply asap.
Thanks and regards and do keep in touch.
