Team;
As suggested by some team members i am attaching my
kmtune and vmstat outputs. The kernel tuning was done
by a HP expert. All users come in from PC thru
xemulation.
Earlier message:
Team:
We have this issue on an Nclass server running 11.0
64bit with 20Gig memory. We run a tool called SRM
(System Resource Manager), which would look into
Processor utilization, run queue and Page>Limit/Sec
(This figure indicates the amount of time that the
number of paged out virtual memory pages was greater
than the Limit per second threshold). On this box it
shows that the page>Limit/Sec has reached high levels
(yellow) while the same data also shows that it has
13.4 Gig of free memory at all times. With this kind
of free memory, I would assume that the machine never
has to swap memory pages. Obviously, the tool uses
commands such as sar, vmstat, swapinfo and other
popular Unix commands. This is a critical performance
indicator because a great decline in performance
occurs once the system passes this threshold. Please
advice where to start and why this may happen and what
to look into.
Thanks
Joe.
