When performing disaster recovery using the streaming replication method, the database cluster must be configured based on the "4.14.3.2 Defining a Streaming Replication Method". After deployment, database data is synchronized between the production environment and the disaster recovery environment using the streaming replication method, so no operation is required during operation.

When a disaster occurs, it is necessary to promote the FEPCluster in the disaster recovery environment. For promotion of FEPCluster in a disaster recovery environment, refer to "5.11.2.2 Performing Disaster Recovery".
