System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones

Zone-Wide Resource Controls in an lx Branded Zone

The preferred, simpler method for setting a zone-wide resource control is to use the property name instead of the rctl resource. These limits are specified for both the global and non-global zones.

The global administrator can also set privileged zone-wide resource controls for a zone by using the rctl resource.

Zone-wide resource controls limit the total resource usage of all process entities within a zone. These limits are specified for both the global and non-global zones by using the zonecfg command. For instructions, see How to Configure the lx Branded Zone.

The following resource controls are currently available:
