Use rs_init, SAP Control Center, or isql with RCL commands to interact with Replication Server.
rs_init allows you to set up a new Replication Server and add new databases to the system.
The SAP Control Center provides a graphical user interface for managing and monitoring the servers and their components in the replication environment.
You execute RCL commands by connecting to Replication Server using a client application. You can use the isql or a custom application program that you create with Open Client Client-Library.
RCL commands are similar to Transact-SQL commands. See Replication Server Commands in the Replication Server Reference Manual for the complete syntax for all RCL commands.
Since many of the commands are used on an as-needed basis, isql is a convenient way to execute them.
