Abstract

Embodiments are provided for replicating a relational source database associated with a transaction log of the relational source database. In operation, embodiments may perform receiving a request for replicating data of the relational source database to a relational target database and identifying a first start position within the transaction log. Upon having identified the first start position, embodiments may further perform waiting at least a time period for ensuring that each transaction currently executing on the relational source database at a moment of receiving said request has terminated at an end of said time period. After having waited said time period, embodiments may perform an asynchronously creating of a copy of data of the relational source database to produce a created copy. In turn, embodiments may perform writing the created copy to the relational target database and identifying a repair start position within the transaction log.
