Zone-Wide Resource Controls

Zone-wide resource controls limit the total resource usage of all process entities within a zone. Zone-wide resource controls can also be set using global property names as described in Setting Zone-Wide Resource Controls and How to Configure the Zone.

Table 6–2 Zone-Wide Resource Controls

Control Name 


Default Unit 


Solaris 10 5/08: Absolute limit on the amount of CPU resources that can be consumed by a non-global zone. A value of 100 means 100% of one CPU as the project.cpu-cap setting. A value of 125 is 125%, because 100% 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. 

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

Size (bytes) 


Maximum number of LWPs simultaneously available to this zone 

Quantity (LWPs) 


Maximum number of message queue IDs allowed for this zone 

Quantity (message queue IDs) 


Maximum number of semaphore IDs allowed for this zone 

Quantity (semaphore IDs) 


Maximum number of shared memory IDs allowed for this zone 

Quantity (shared memory IDs) 


Total amount of System V shared memory allowed for this zone 

Size (bytes) 


Total amount of swap that can be consumed by user process address space mappings and tmpfs mounts for this zone.

Size (bytes) 

For information on configuring zone-wide resource controls, see Resource Type Properties and How to Configure the Zone. To use zone-wide resource controls in lx branded zones, see How to Configure, Verify, and Commit the lx Branded Zone.

Note that it is possible to apply a zone-wide resource control to the global zone. See Chapter 17, Non-Global Zone Configuration (Overview) and Using the Fair Share Scheduler on a Solaris System With Zones Installed for additional information.
