Heartbeat Timeout
Use this system parameter to increase or decrease the communication timeout interval (in minutes) before CDC Replication detects a communication problem and attempts to stop active replication processes.
Versions supported—CDC Replication Engine for Db2® for i version 6.1 and later
CDC Replication sends internal heartbeat notifications between the source and target systems to verify communications and the status of replication processes for each active subscription. If the source or target do not receive a reply to a notification within the specified timeout interval, then CDC Replication determines that a problem has occurred and attempts to stop all its source and target processes for each active subscription.
CDC Replication places notifications (message identifiers DMU3165 and DMU0647) in the Event Log when a heartbeat timeout occurs.
