PROBLEM TO BE SOLVED: To provide a method and system for managing a replicated database instance in a database environment.SOLUTION: A method comprises, under control of one or more computer systems configured with executable instructions; monitoring state information for each of a primary instance replica and a secondary instance replica in a database environment using a monitoring component of a separate control environment; responding to the fact that the monitoring component is unable to communicate with one of the first and second instance replicas by determining failure information including information on whether the first and second instance replicas are able to communicate with each other and whether the first and second instance replicas have a common data generation identifier; determining whether to perform a failover operation or a recover process based at least in part on the failure information.SELECTED DRAWING: Figure 3 |
