System Administration Guide: Virtualization Using the Solaris Operating System

ProcedureHow to Associate a Pool With a Scheduling Class

You can associate a pool with a scheduling class so that all processes bound to the pool use this scheduler. To do this, set the pool.scheduler property to the name of the scheduler. This example associates the pool pool_batch with the fair share scheduler (FSS).

  1. Become superuser, or assume a role that includes the Process Management profile.

    The System Administrator role includes the Process Management profile. For more information about roles, see Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.

  2. Modify pool pool_batch to be associated with the FSS.


    # poolcfg -c 'modify pool pool_batch (string pool.scheduler="FSS")'
    
  3. Display the edited configuration.


    # poolcfg -c info

  4. Commit the configuration at /etc/pooladm.conf:


    # pooladm -c
    
  5. (Optional) To copy the dynamic configuration to a static configuration file called /tmp/backup, type the following:


    # pooladm -s /tmp/backup
