The RASD, an embedded SQL Anywhere database, starts up when the Replication Agent starts up. By default, the SQL Anywhere host value is localhost, and the SQL Anywhere port number is the Replication Agent port number +1.If you cannot start the Replication Agent instance because these values conflict with the host environment, you may change them by editing the Replication Agent configuration parameters asa_host and asa_port, found in the instance configuration file. For example:
$SYBASE/RAX-15_1/<instance>/<instance>.cfg
Where <instance> is the name of your Replication Agent instance.
The Replication Agent must be restarted after changing these configurations.
