How to Define Pools Configuration Objectives

Language:

You can specify objectives for the poold daemon to consider when taking corrective action.

In the following procedure, the wt-load objective is being set so that the poold daemon tries to match resource allocation to resource utilization. The locality objective is disabled to assist in achieving this configuration goal.

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

Modify system tester to favor the wt-load objective.

$ poolcfg -c 'modify system tester (string system.poold.objectives="wt-load")'

Disable the locality objective for the default processor set.

$ poolcfg -c 'modify pset pset_default (string pset.poold.objectives="locality none")'one line

Disable the locality objective for the pset_batch processor set.

$ poolcfg -c 'modify pset pset_batch (string pset.poold.objectives="locality none")'one line

Display the edited configuration.

Commit the configuration at /etc/pooladm.conf.
```
$ pooladm -c
```
(Optional) Copy the dynamic configuration to a static configuration file called /tmp/backup.
```
$ pooladm -s /tmp/backup
```
