Abstract
A method, a system, and a computer program product for executing a takeover process. A takeover process of a primary computing system by a secondary computing system is triggered. The secondary computing system stores transaction data replicated from the primary computing system. Writing of a redo log of transaction data of one or more transactions into storage by the primary computing system is suspended. The redo log is written by the primary computing system prior to the suspending is transmitted to the secondary computing system. The takeover process of the primary computing system by the secondary computing system is executed upon receiving and persisting the redo log at the secondary computing system.
