Experimental Physics and Industrial Control System

Hi Geyang,
Under Linux (and the other host-type OSs), an IOC is a single
multi-threaded process.
So, naturally, "rebooting" an IOC means restarting the IOC process,
which is usually done by shutting down or killing the current
process and letting the wrapper (e.g. procServ) handle the restart.
Very often, many Linux IOCs are run on a single host: 20-30 are
quite common, I have seen up >300 IOCs on a server-class Solaris
machine.
I am sure you understand that allowing to reboot the server from any
of these IOCs would be a bad idea.
Also, rebooting a server usually needs root access. IOCs should not
be run as root.
Cheers,
~Ralph

in IOC Status and Control
(devIocStats), it has an reboot function in subroutine record,
that is ,in devIocStatsSub.c file, it calls
reboot function of linux.
Thanks a lot for your help.
