PROBLEM TO BE SOLVED: To provide a method and a system for managing replicated database instances within a database environment.SOLUTION: A method includes the steps of: monitoring state information for each of a primary instance replica and a secondary instance replica within a database environment, while using a monitoring component in a separate control environment, under control of one or more computer systems configured using executable instructions; determining fail information including whether the primary instance replica and the secondary instance replica can communicate with each other and whether the primary instance replica and the secondary instance replica have a common data generation identifier in response to impossibility for the monitoring component to communicate with at least the primary instance replica or the secondary instance replica; and determining whether a failover operation or recovery process can be executed, at least partially on the basis of the fail information. |
