ID Server

The first Replication Server you install is the ID Server. It must be running when you install new Replication Servers or add databases to the replication system.

In addition to the usual Replication Server tasks, the Replication Server acting as the ID Server assigns a unique ID number to every Replication Server and database in the replication system. The ID Server also maintains version information for the replication system. Otherwise, the ID Server is like any other Replication Server.

When you install a new Replication Server or add a database to your replication system, the ID Server must be running. This allows the new Replication Server, or the Replication Server that manages the new database, to log in and retrieve an ID number. The ID Server must also be running whenever you create a route.

You must install the ID Server before you install any other Replication Server. If you have only one Replication Server, or if you are installing Replication Server for the first time, then that Replication Server is also the ID Server. If you are adding a Replication Server to an existing replication system, you must know the name of the Replication Server in the system that is the ID Server.

Warning! The ID Server is critical to your replication environment, and is difficult to move once it has been installed.

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.
