With version 15.2, Replication Server introduces Replication Server gateway, which minimizes explicit login into the different servers, and makes managing a replication system easier.
In managing a replication system, the replication system administrator (RSA) must log in to multiple replication servers, ID servers, and the corresponding Replication Server System Database (RSSD). The RSA must also frequently switch logins between Replication Server and the RSSD.
The Replication Server gateway uses your RSSD primary user name and password to log in to RSSD, your ID server user name and password to log into ID Server, your remote server identification (RSI) to log into a remote Replication Server, and your maintenance user ID to log into the remote Adaptive Server. You do not need to supply this information more than once, when you access Replication Server itself.
