How 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. Assume the root role.

    For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.4.

  2. Modify the pool 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) Copy the dynamic configuration to a static configuration file.
    $ pooladm -s /tmp/backup
