Activating and Deactivating Pools Configurations

Use pooladm(1M) to make a particular pool configuration active or to remove an active pools configuration.

How to Activate a Pools Configuration

To activate the configuration in the default static configuration file, /etc/pooladm.conf, invoke pooladm with the -c option, "commit configuration."

1. Become superuser.

2. Type the following:

   # /usr/sbin/pooladm -c

How to Deactivate a Pools Configuration

To remove the running configuration and all associated resources, such as processor sets, use the -x option for "remove configuration."

1. Become superuser.

2. Type the following:

   # /usr/sbin/pooladm -x

The -x option to pooladm removes the dynamic private configuration file as well as all resource configurations that are associated with the dynamic configuration. Thus, the -x option provides a mechanism for recovering from a poorly designed pools configuration. All processes share all of the resources on the machine.

Mixing scheduling classes within one processor set can lead to unpredictable results. If you use pooladm -x to recover from a bad configuration, you should then use priocntl(1) to move running processes into a different scheduling class.
