runclass - Runs a command in a specific scheduling class
/usr/sbin/runclass class_name command [argument ...]
An argument to the command being run.
The name of the scheduling class in which the command is run.
command The command being run.
The runclass utility lets you run a command (including any of its argu-
ments) in a scheduling class. All the threads created by the command pro-
cess, and its subprocesses, inherit the class binding. Unless the user
entering the runclass command has superuser authority, the allotted CPU
percentage of the specified class may not be higher than the user's current
class (if any).
Normally, any command run by root is not subject to class scheduling. How-
ever, commands started by root with the runclass command are subject to the
limitations of the specified class.
If class scheduling is not enabled, the runclass command terminates and
does not execute the requested command.
Scheduling classes are usually created by the class_admin command, which
also allows you to move processes to a scheduling class after they start.
The runclass command is the way you can execute an application so that its
processes automatically start up in a scheduling class.
The runclass command changes the process group of itself and all processes
created by it. This means that if runclass is executed from a script,
entering Control C from the terminal will not kill these processes. In this
case, using the kill command is required.
Commands: kill(1), class_admin(8)
