Oracle GoldenGate Initial Load Methods Oracle GoldenGate Initial Load Methods Initial Load Direct Load Overview: Initial Load Direct Load is a method that streams the initial data from the source to the target in real-time. This approach utilizes the Extract and Replicat processes to capture and apply data changes continuously. Continuous Capture and Apply: The Extract process reads the data from the source and sends it directly to the target Replicat process, which applies the data immediately. Real-Time Data Streaming: It ensures that the data is streamed in real-time, which is beneficial for scenarios where minimizing latency is crucial. No Intermediate Files: Unlike some other methods, there are no intermediate files or staging areas; the data moves directly from source to target. Transaction Consistency: Ensures transactional consistency, making it suitable for environments where maintaining ...

Goldengate initial load options - File to Replicat This method allows the Extract process to write to a file on the target system, which the Replicat applies using SQL INSERT statements.  The Extract process generates a file in a universal format for the Replicat to load. This approach fundamentally resembles the standard GoldenGate data replication method used for change data capture (CDC). During the initial load, you can enable CDC. In a live environment, you should use the SQLPREDICATE key to specify the SCN# to maintain data integrity. Please follow the below steps to enable goldengate initial load using File to Replicat method On source: Add initial load extract process. Create a parameter file. Verify task(in...
