A zone creator must have CREATE ZONE privilege to create a zone. The zone creator then uses the following syntax to create a zone:
CREATE ZONE zone_name ROOT root_name ;
The root_name must be an existing user or database that has no preexisting objects, descendants, roles, profiles, or grants.
You can create a secure zone without a ROOT, and use ALTER ZONE later to add a ROOT database or user. You can also use ALTER ZONE to delink the ROOT from a secure zone before you drop the zone.
