For low volume Oracle sources using the Oracle LogMiner implementation (Streamkap's default), it is possible that the log becomes stale due to a lack of change events. As a result, events may not be captured by the Connector.
To address this, the heartbeat process involves writing an insert or update to a heartbeat table every 1 second to generate a change event.
CREATE TABLE heartbeat ( id TIMESTAMP );
GRANT INSERT, UPDATE ON heartbeat TO C##STREAMKAP_USER;
- Within Streamkap, go to the Oracle Source and add the heartbeat table to the schema
- Streamkap should start inserting records to the heartbeat table using this command every 1 second
INSERT INTO heartbeat (id) values (SYSDATE)
- Look for entries in the heartbeat table to verify this is working
