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 Zones Resource Controls


Control Name	Description	Default Unit
`zone.cpu-cap`	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)
`zone.cpu-shares`	Number of fair share scheduler (FSS) CPU shares for this zone	Quantity (shares)
`zone.max-locked-memory`	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)
`zone.max-lwps`	Maximum number of LWPs simultaneously available to this zone	Quantity (LWPs)
`zone.max-msg-ids`	Maximum number of message queue IDs allowed for this zone	Quantity (message queue IDs)
`zone.max-sem-ids`	Maximum number of semaphore IDs allowed for this zone	Quantity (semaphore IDs)
`zone.max-shm-ids`	Maximum number of shared memory IDs allowed for this zone	Quantity (shared memory IDs)
`zone.max-shm-memory`	Total amount of System V shared memory allowed for this zone	Size (bytes)
`zone.max-swap`	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 Using the Fair Share Scheduler on a Solaris System With Zones Installed for additional information.
