Each Replication Server uses login names that are distinct
from data server login names. Many clients do not need a Replication
Server login name because they accomplish their work through data
server applications.
Replication Server Login Names
When you install a Replication Server, rs_init creates Replication Server login names that other Replication Servers and Replication Agents use to log in to Replication Server.
Data Server Login Names
Data server login names are used with a client application to connect to a data server. A database administrator creates and manages data server login accounts.
Data Server Maintenance User Login Name
Replication Server uses a maintenance user login name for each local data server database that contains replicated tables. Replication Server uses this login to maintain replicated tables.
