6 Multi-Master Replication Operation : 6.11 Ensuring High Availability

Note: Replication history may take a longer period of time to replicate from the controller database to the other publication databases, therefore it is possible that some replication history may be lost if access to the controller database fails, and a switchover is made to another publication database to act as the controller database. See Section 7.4 for information on replication history.
The controller database authentication and connection information is modified accordingly in the xDB Replication Configuration file (see Section 2.3.1.3). Thus, any subsequent startups of the publication and subscription servers use this newly designated controller database.
