Replication system domain refers to all replication system components that use the same ID Server.
Some organizations have multiple independent replication systems. Since the ID Server determines member Replication Servers and databases in a replication system, one replication system in an organization with multiple replication systems is also called an ID Server domain.
No special steps are required to set up multiple ID Server domains. Every Replication Server or database belongs to one replication system and has a unique ID number in that ID Server domain.
Replication Servers in different domains cannot exchange data. Each domain must be treated as a separate replication system with no cross-communication between them. You cannot create a route between Replication Servers in different domains.
A database can be managed by only one Replication Server in one domain. Any given database is in one, and only one, ID Server’s domain. This means that you cannot create multiple connections to the same database from different domains.
