NAME    [Toc]    [Back]

       runclass - Runs a command in a specific scheduling class

SYNOPSIS    [Toc]    [Back]

       /usr/sbin/runclass class_name command [argument ...]

OPERANDS    [Toc]    [Back]

       An  argument  to  the  command being run.  The name of the
       scheduling class in which the command is run.  The command
       being run.

DESCRIPTION    [Toc]    [Back]

       The runclass utility lets you run a command (including any
       of its arguments) in a scheduling class. All  the  threads
       created  by  the  command  process,  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).

       If  class  scheduling is not enabled, the runclass command
       terminates and does not execute the requested command.

NOTES    [Toc]    [Back]

       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.
