  • PREDICTING VALIDITY OF DATA REPLICATION PRIOR TO ACTUAL REPLICATION IN A TRANSACTION PROCESSING SYSTEM
    Publication number: 20150213099
    Abstract: A method, computer program product and computer system to validate a write of a replica record to a replica data store in a transaction processing system, the replica record duplicating a source record in a source data store. The transaction processing system obtains a value associated with a record location of the source record in the source data store. The transaction processing system predicts a value associated with a record location of the replica record in the replica data store and responsive to the obtained value associated with the source record location not corresponding to the predicted value associated with the replica record location, not writing the replica record.
