Abstract: In response to receiving a request for replicating data of a source database to a relational target database, a first start position (SP1) representing the most recent log position within a transaction log is identified. After a time period, waiting to ensure that each currently executing transaction (T1.1, T2.1 etc.) has terminated, asynchronously creating a copy of the data of the source database excluding any changes by transactions not committed. After completion of copying, identifying a repair start position (RSLP) within the transaction log to identify transactions which started after the first start position and which committed before the repair start position in order to execute those transactions.
