Thanks erman.

We have quad core cpu

[oraprod@node1 ~]$ cat /proc/cpuinfo|grep -i 'core id'|sort|uniq
core id         : 0
core id         : 1
core id         : 2
core id         : 3

[oraprod@node1~]$ cat /proc/cpuinfo|grep -i 'physical id'|sort|uniq
physical id     : 0


In general,manual says load average or say run queue(r column in vmstat) should not exceed the number of cores consistently.In this case,if i have quad core cpu with HTT enabled,what will be the number of cores to consider...is it 4 or 8

Thank you
