For additional information about using a resource management feature in a zone, also refer to the chapter that describes the feature in Part I, Oracle Solaris Resource Management.
Any of the resource controls and attributes described in the resource management chapters can be set in the global and non-global zone /etc/project file, NIS map, or LDAP directory service. The settings for a given zone affect only that zone. A project running autonomously in different zones can have controls set individually in each zone. For example, Project A in the global zone can be set project.cpu-shares=10 while Project A in a non-global zone can be set project.cpu-shares=5. You could have several instances of rcapd running on the system, with each instance operating only on its zone.
The resource controls and attributes used in a zone to control projects, tasks, and processes within that zone are subject to the additional requirements regarding pools and the zone-wide resource controls.
A non-global zone can be associated with one resource pool, although the pool need not be exclusively assigned to a particular zone. Multiple non-global zones can share the resources of one pool. Processes in the global zone, however, can be bound by a sufficiently privileged process to any pool. The resource controller poold only runs in the global zone, where there is more than one pool for it to operate on. The poolstat utility run in a non-global zone displays only information about the pool associated with the zone. The pooladm command run without arguments in a non-global zone displays only information about the pool associated with the zone.
Zone-wide resource controls do not take effect when they are set in the project file. A zone-wide resource control is set through the zonecfg utility.
