Replication Server uses the system-provided function-string class rs_oracle_function_class for the standby DSI, which is the connection to the standby database.
rs_marker – marks the point in the transaction log of the active database where replication must be enabled for the standby connection. Everything before the marker is not replicated while everything after the marker is replicated.
rs_repl_off – disables replication for the current session.
rs_triggers_reset – disables all triggers at the replicate database that triggers firing for the current session.
rs_trunc_set – moves the truncation point used by the Replication Agent for Oracle to the end of the transaction log.
