All applications are fully functional in the global zone, as they would be in a conventional Oracle Solaris operating system. Most applications should run without problem in a non-global environment as long as the application does not need any privileges. If an application does require privileges, then the developer needs to take a close look at which privileges are needed and how a particular privilege is used. If a privilege is required, then a system administrator can assign the needed privilege to the zone. See Configurable Privileges in Introduction to Oracle Solaris Zones .
