Abstract

Transaction ping-pong is selectively prevented in a bidirectional database replication system (28). The system (28) has a plurality of nodes (30, 40) connected via communication media in a topology. Each node (30, 40) includes a database (32, 42) and a transaction transmitter or collector (36, 50) which sends transactions posted to the database to a database at one or more other nodes for replication in the databases of the one or more other nodes. All transactions to be posted to databases in remote nodes that were sent by a local node are detected, and the database at the local node is inhibited from posting selective transactions which were detected as being originally sent by the local node.
