  • Automatic prunning for log-based replication
    Patent number: 6473776
    Abstract: Automatic pruning of a log used in log-based replication of database tables within a relational database management system. An optimal point at which to prune the log is periodically determined, such that the optimal point provides a minimum amount of storage space for the log and yet ensures that all updates to the database table can be properly replicated from the log. The log is then automatically pruned of selected records prior to the optimal point.
    Type: Grant
