Hello All,
I have been reading several entries in the archives explaining the output of
swapinfo in regards to memory and device swap but apparently I am having a
mental block because I can't seem to comprehend the explanations. Here is
my output form swapinfo -t:
# swapinfo -t
Kb Kb Kb PCT START/
Kb
TYPE AVAIL USED FREE USED LIMIT
RESERVE PRI NAME
dev 2097152 0 2097152 0% 0
- 1 /dev/vg00/lvol2
reserve - 1468224 -1468224
memory 3299740 1220268 2079472 37%
total 5396892 2688492 2708400 50% -
0 -
Before re-booting this machine the "memory" line showed 100% and the "dev"
seems to always show 0% as if it is never using the device swap space. With
"dev" line at 0% I am getting errors from oracle saying out of space and
eventually the system is un-usable. In glance it shows swap at 100% (40% of
it is "R" I assume for reserved) and memory in glance was showing 76%. If
someone could explain this output in layman's terms or point me to a white
paper that could explain it, I would greatly appreciate it.
Thanks,
