Resource Controls to Limit Locked Physical Memory

This system resource enhancement is new in the Solaris Express 11/06 release.

To limit the amount of locked physical memory available to a zone on a Solaris OS with zones installed, use the zone.max-locked-memory zone-wide resource control. The resource control is set through the add rctl resource property in zonecfg for non-global zones. With the introduction of zone.max-locked-memory, the proc_lock_memory privilege is now part of the standard default set of zone privileges.

The allocation of the locked physical memory resource across projects within the zone can be controlled by using the project.max-locked-memory resource control.

The project.max-locked-memory resource control replaces the project.max-device-locked-memory resource control, which has been removed from the Solaris OS.
