Holger,
How did you relate the kproc to an aioserver?
I have minservers set to 10 and only show 10 aioservers via pstat -a, but I
see many more kprocs.
I can't tell which kproc relates to which aioserver or uid?
I'm trying to prove whether sybase is using aio or not. I'm told it won't
start without aio, but can't tell if it's using it or not.
My aio is defined as follows:
# lsattr -El aio0
minservers 10 MINIMUM number of servers True
maxservers 100 MAXIMUM number of servers True
maxreqs 4096 Maximum number of REQUESTS True
kprocprio 39 Server PRIORITY True
autoconfig available STATE to be configured at system restart True
fastpath enable State of fast path True
Thanks,
Kevin Adams

Subject: [aix-l] aio minservers
Hello,
I had a look at the cpu usage of my aioservers (ps -k, pstat -a).
Min/maxserver are 240/480.
The first 240 servers have very few usage (uid root). The servers #241-480
have high, distributed usage (uid oracle).
That looks as if oracle cant use the root-aioservers.
So where is the point to set minservers to maxservers/2 ?
Btw. I noticed that this rule is in AIX Perf.Guide 3.x/4.x but not in 5.x.
In 5.x there is written one should keep the default of 1.
Regards,
Holger
