HPUX in Real Time processing mode

[Shivkumar]

We are running weblogic server 7.x on hpux machines having 8 cpu and 16 GB Ram. I have heard that real time processing is supported on some modern unix flavors.

I just wanted to know whether real time computing supported on hpux ? if yes then is it possible to run any application in real time ?

What are commands to run any application in real time mode ?

Thanks,
Shiv

hi
yes, hpux supports two real time processing, hpux style and posix style.
with
rtprio
root can start any process in real time priority.
BUT before trying read the man page and be very carefull with it: if you run a command that use only cpu like a schell script with a loop like this
i=1
while ((i<1000000)); do
let i=i+1
done
a cpu will be compltely and only dedicated to that process so it'w very easy to stop averything working with bad rtprio commands

hope it helps
