How to Change Scheduling Parameters of a Timesharing Process (priocntl)

1. Assume the root role.

   See Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2 .

2. Change the scheduling parameters of a running timesharing process.

   # priocntl -s -m user-limit [-p user-priority] -i ID type ID list

   –s

   Lets you set the upper limit on the user priority range and change the current priority.

   –m user-limit

   When you use the –p option, specifies the maximum amount you can raise or lower the priority.

   –p user-priority

   Allows you to designate a priority.

   –i ID type ID list

   Uses a combination of ID type and ID list to identify the process or processes. ID type specifies the type of ID, such as the process ID or the user ID. ID list identifies a list of process IDs or user IDs.

3. Verify the process status.

   # ps -ecl | grep ID list

Example 2-5  Changing Scheduling Parameters of a Timesharing Process (priocntl)

The following example shows how to execute a command with a 500-millisecond time slice, a priority of 20 in the RT class, and a global priority of 120.

# priocntl -e -c RT -m 500 -p 20 myprog
# ps -ecl | grep myprog
