Setting up domain separation involves activating the plugin, setting options, and
assigning users and records to domains.
Activating the Domain Extension plugin enables these features:
- Domain separation is based on the Domain
- Delegated administration lets each domain have separate policy.
- All records are part of the global domain.
- The current user's domain determines the domain to use when viewing or operating on a record
in a different domain.
Domain separation replaces Company Separation. Starting with the Helsinki release, the Company
Separation plugin can no longer be activated. However, if company separation is already active
when you activate domain separation, both plugins are active at the same time. You can control
the company separation activation status with the glide.db.separation.field
Note: Domain paths are used for all customers on Helsinki and later. Domain numbering is no
longer used. ServiceNow support can assist in the upgrade.
Domain separation plugins
The plugin combines the features of the previous plugins:
- Domain Support (version 1.0)
- Domain Support - Common
- Domain Support - Partitioning (Data separation)
- Domain Support - Delegated Administration
- Domain Number Support
In addition to functionality in the Domain Support - Domain Extensions Installer plugin, this
plugin installs Domain Support - Domain Extensions that include further domain separation
enhancements for all domain customers including Managed Service Providers. If the Domain Support
plugin is already active, content in the Domain Support - Domain Extensions plugin will not be
installed to avoid potential conflict with an existing implementation.
Domain separation compared to separate instances
While the behavior offered with domain separation provides multi-tenancy support,
multi-tenancy is still contained within a single instance.
This means that some global properties, some global data, and some global processes are
shared across all domains. For example, the option to have the system Remember
me on the login page of the system is global and cannot be specified per domain.
If you need complete and total separation of all system properties and do not require global
reporting or global processes, then separate instances is the best option.
