With Return Two Safe replication, in case of a master failure you would have to recover by duplicating the master from the subscriber. This is because transactions are committed first on the subscriber then confirmation is given to the master.
Master catchup is not available for all replication configurations. Using TRANSMIT DURABLE (the default except for RETURN TWOSAFE), there is no need for master catchup since all data sent by replication is also guaranteed recoverable locally (from disk) and so after a master failure one can simply restart the master datastore and everything will sync up without any data loss.
If you attempt to connect to the master data store before the 'master catchup' has completed, you may encounter the following error
Check that the replication agents are started so they can both talk to each other, and hence the "master catchup" can occur.
