The ID Server is a Replication Server that registers all Replication Servers and databases in the replication system. The ID Server must be running each time a:
Replication Server is installed
Route is created
Database connection is created or dropped
Because of this requirement, the ID Server is the first Replication Server that you start when you install a replication system.
The ID Server must have a login name for Replication Servers to use when they connect to the ID Server. The login name is recorded in the configuration files of all Replication Servers in the replication system by the rs_init configuration program.
Once you have selected a login name for the ID Server,
you cannot change to a different Replication Server. Sybase does
not support any procedures that change the login name of the ID
Server in the configuration files.
See Chapter 4, “Managing a Replication System” for information about the configuration file.
Replication system domain refers to all replication system components that use the same ID Server. You can set up multiple replication system domains, with the following restrictions:
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.
See “Adding a replication system domain” for guidelines and restrictions on adding multiple system domains.
