processor count using adb in vPar environment

Tim Nelson — Wed, 01 Mar 2006 10:27:27 GMT

For the longest time I have been using the below to retrieve the number of processors on a system for reporting.
echo "runningprocs/D"|adb -k /stand/vmunix /dev/mem

In a vPar environment with ICOD this reports all procs minus the two bound to the other vPar.

Is there another kernel var that can be used to report the current number of processors active in a vPar I only see runningprocs in /usr/include/sys/ki_calls.h ??

Tim,

How about the vparstatus command?

That is where I was headed next if no answer to using adb.

Note:
Also noticed adb hangs on one partition and not the other.

Using adb64 works for some items but not others.

I don't think so -- and I wouldn't recommend it anyway. Reading kernel internal variables is a good way to have stuff break on you between patches/releases in the first place.

You can get this information from pstat, attaching a C program to do so.

Here is some more info relating to adb failing/hanging in a vpar environment. KnowledgeBase DOC. 4000067733

adb fails/hangs in vPar as it has trouble accessing the higher memory region that the vPar > 1 runs in. Aquire the new ADB or use /dev/kmem instead of /dev/mem

vparstatus|awk 'NF==9 {print $0}'|awk '{print $1,$4,$5}'|while read vpar
c1 c2;do
printf " %12s %4d cpus\n" $vpar $((c1+c2))
done
