You can manually move a project's processes from their current scheduling class to the FSS scheduling class.
Become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.
Move processes that run in project ID 10 to the FSS scheduling class.
# priocntl -s -c FSS -i projid 10
The project's processes again run in the default scheduling class after reboot.
