Loss detection and recovery

Creating a warm standby application introduces additional types of loss detection messages into a replication system. See Chapter 7, “Replication System Recovery” for general information on Replication Server recovery, and for recovery procedures.

If you rebuild queues in a Replication Server that participates in a warm standby application, the Replication Server may detect losses between any of the following databases:

**Table 3-8: Loss detection in warm standby applications**
Loss detected from	To
Logical replicate database	Logical primary database
Logical primary database	Physical replicate database
Physical primary database	Logical replicate database
Physical active database	Physical standby database
Logical primary database	Replication Server

If you need to use the ignore loss command in database recovery operations where a warm standby application is involved, use the same logical or physical data server and database designations that appear in the loss detection messages you received.
