How to Designate a Process Priority

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 default classes are TS (timesharing) or RT (real-time).
   -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 -20 to +20.

3. Verify the process status by using the ps -ecl command.

   # ps -ecl | grep command_name

Example--Designating a Priority

The following example starts the find command with the highest possible user-supplied priority.

# priocntl -e -c TS -m 20 -p 20 find . -name core -print
# ps -ecl | grep find
