Replication Agent instance directories are created under the Replication Agent base directory when you create a Replication Agent instance. The Replication Agent base directory (RAX-15_1) and the installation directory (sybase) are created when you install the Replication Agent software.
A single installation (on a single host machine) can
support multiple Replication Agent instances. Each instance directory
resides under the Replication Agent base directory created when
you install the software.
