Domains in the Site Context
When a Windchill solution is installed, the following domains are initially defined in the site context:
Domain Names
Description
/ (root )
Sets rules that govern the entire enterprise.
/System
Serves as the default domain for most system administration objects, including queues and life cycle definitions. /System is the default domain of the Administrators group.
The /System domain is not intended for general user business objects.
/User
Serves as the default domain for organization objects and as the parent domain for the /Unaffiliated domain and for organization context domains that hold the users (and their personal cabinets) for that organization.
/Default
Serves as the default domain for the initialization of business information objects.
/SessionIterationDomain
Serves as the default domain for internal session processes. Do not modify the policies set for this domain.
/Unaffiliated
Serves as the default domain for users who are not associated with any organization. These users do not have the organization attribute set in their directory service entry. The /Unaffiliated domain is a child domain of the /User domain.
The root, /System, /User, and /Default domains cannot be moved or deleted. Also the domain names of these domains and of the /Unaffiliated domain are configured through the wt.properties file.
The /System, /User, /Default, and /SessionIterationDomain domains belong to the / (root) domain. Additional domains can be defined and associated with the root domain, or domains can be nested by defining them as children of another domain. This allows you to define a hierarchy of domains and then define policies at each level in the hierarchy.
