You can configure or instruct Replication Agent for Oracle to send a resync database marker to Replication Server to indicate that a resynchronization effort is in progress.
When you restart Replication Agent in resync mode, Replication Agent sends the resync database marker to Replication Server as the first message before Replication Agent sends any SQL data definition language (DDL) or data manipulation language (DML) transactions. Multiple replicate databases for the same primary database all receive the same resync marker since they each have a DSI outbound queue.
For each DSI that resumes with the skip to resync marker parameter, the DSI outbound queue records in the Replication Server system log that DSI has received the resync marker and also records that from that point forward, DSI rejects committed transactions until it receives the dump database marker.
In Replication Agent for Oracle, use resume with the resync or resync, init parameters to support these corresponding options for sending the resync database marker. See Replication Agent Reference Manual > Command Reference > resume.
