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:

Absolute limit on the amount of CPU resources for this zone. A value of 100 means 100 percent of one CPU as the project.cpu-cap setting. A value of 125 is 125 percent, because 100 percent corresponds to one full CPU on the system when using CPU caps.

Quantity (number of CPUs) 




Number of fair share scheduler (FSS) CPU shares for this zone. 

Quantity (shares) 



Total amount of physical locked memory available to a zone. 

If the privilege priv_proc_lock_memory is assigned to a zone, consider setting this resource control as well, to prevent that zone from locking all memory.
