## Support for Oracle Solaris Zones

Oracle Solaris zones provide a means of creating virtualized operating system environments within an instance of the Oracle Solaris OS. Oracle Solaris zones enable one or more applications to run in isolation from other activity on your system. The Oracle Solaris zones facility is described in Part II, Oracle Solaris Zones, in Oracle Solaris Administration: Oracle Solaris Zones, Oracle Solaris 10 Zones, and Resource Management. For information on zone clusters, see Zone Cluster Membership and Performing Zone Cluster Administrative Tasks in Oracle Solaris Cluster System Administration Guide,
