PatchPro can be used in the global zone and in any non-global zone.
If run in the global zone, PatchPro uses the existing patch database and
patch tools to patch the global and all non-global zones for all
software that is installed on the global zone. No software installed in a
non-global zone that is not also installed in the global zone will be
taken into account.
A zone administrator can run PatchPro in a non-global zone to patch the
software installed in the non-global zone.
