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 Zone Components in Introduction to Oracle Solaris Zones .

Table 6-2  Zones Resource Controls
Control Name
Default Unit
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)
Maximum number of lofi devices that can be created by a zone.
The value limits each zone's usage of the minor node namespace.
Quantity (number of lofi devices)
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 process table slots simultaneously available to this zone.
Because both normal processes and zombie processes take up process table slots, the max-processes control thus protects against zombies exhausting the process table. Because zombie processes do not have any LWPs by definition, the max-lwps control cannot protect against this possibility.
Quantity (process table slots)
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)

Note that it is possible to apply a zone-wide resource control to the global zone.
