How to Designate a Process Priority (priocntl)

1. Become superuser.

2. Start a process with a designated priority.

   # priocntl -e -c class -m userlimit -p pri command-name

   -e	Executes the command.
   -c class	Specifies the class within which to run the process. The valid classes are TS (timesharing), RT (real time), IA (interactive), FSS (fair share), or FX (fixed priority).
   -m userlimit	Specifies the maximum amount you can raise or lower your priority, when using the -p option.
   -p pri command-name	Lets you specify the relative priority in the RT class, for a real-time thread. For a timesharing process, the -p option lets you specify the user-supplied priority, which ranges from -60 to +60.

3. Verify the process status.

   # ps -ecl | grep command-name

Example—Designating a Process Priority (priocntl)

The following example shows how to start the find command with the highest possible user-supplied priority.

# priocntl -e -c TS -m 60 -p 60 find . -name core -print
# ps -ecl | grep find
