Use rs_init, Sybase Central , 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 Sybase Central Replication Manager plug-in component provides a graphical user interface for performing many of the tasks associated with managing a Replication Server system.
You execute RCL commands by connecting to Replication Server using a client application. You can use a utility program such as Sybase Central or isql, or you can use a custom application program that you create with Open Client Client-Library.
RCL commands are similar to Transact-SQL commands. See Replication Server Reference Manual > Replication Server Commands 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.
