You can load the primary database dump to the replicate database only after you see the relevant messages in the system log.
When Replication Server receives the resync database with init marker:
DSI for data_server.database received and processed Resync Database Marker. DSI is now suspended. Resume after database has been reloaded.
When Replication Server receives the dump database marker:
DSI for data_server.database received and processed Dump Marker. DSI is now suspended. Resume after database has been reloaded.
See Adaptive Server Enterprise Reference Manual: Commands > Commands > load database for instructions about loading the dump to the database you want to resynchronize.
