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.
The runserver file name is constructed based on the name of the server. For example, for a Replication Server named ROME_RS, the runserver file is named RUN_ROME_RS.
