In the Oracle Solaris operating system, the concept of a per-process resource limit has been extended to the task and project entities described in Chapter 2, About Projects and Tasks. These enhancements are provided by the resource controls (rctls) facility. In addition, allocations that were set through the /etc/system tunables are now automatic or configured through the resource controls mechanism as well.
A resource control is identified by the prefix zone, project, task, or process. Resource controls can be observed on a system-wide basis. It is possible to update resource control values on a running system.
For a list of the standard resource controls that are available in this release, see Available Resource Controls. See Available Resource Controls for information on available zone-wide resource controls.
