You can start a Replication Server using the runserver file created by rs_init and connect using isql, then executing shutdown to stop.
Start-up Sequence for Servers
In a production system, you must start Adaptive Servers and Replication Servers, whenever your machine reboots. See your system administrator to do this.
Runserver File
The runserver file is an executable script that contains the complete command line required to start a Replication Server. When you install a new Replication Server to your replication system, rs_init creates a runserver file in the Sybase installation directory.
