1. Oracle GoldenGate provides real-time data integration and replication across heterogeneous database environments. 2. It captures transactional data using log-based change data capture with low overhead. The data is delivered to targets with sub-second latency while maintaining transactional integrity. 3. Oracle GoldenGate supports various use cases including zero-downtime upgrades and migrations, high availability, disaster recovery, data warehousing, and application integration.

14. Differentiator: Performance and Scalability
GoldenGate Capture
• Log-based change data capture
– High volume
– Low overhead
• Decoupled architecture
– Multiple capture processes may be used to scale, but generally not required
– Possible to split “hot” tables into a separate capture process
• Filtering and compression
– Unnecessary change data is discarded immediately
– Updates and deletes are “compressed” by default
14 Copyright © 2011, Oracle and/or its affiliates. All rights
reserved.

15. Differentiator: Performance and Scalability
GoldenGate Delivery
• Decoupled architecture
– Multiple delivery processes may be used to scale
– Possible to split “hot” tables into a separate delivery process
– Possible for multiple delivery processes to split the work for a single table
• Transaction grouping
– Small transactions are grouped by default to reduce commit overhead
15 Copyright © 2011, Oracle and/or its affiliates. All rights
reserved.

16. Differentiator: Transaction Integrity
• Transaction boundaries
– Recorded in GoldenGate trail file
– Transactions ordered in commit sequence
– Boundaries adjusted automatically due to record filtering or trail
splits
• Transaction integrity
– Checkpointing and recovery are based on transaction
boundaries
– Original commit sequence is maintained by the delivery process
16 Copyright © 2011, Oracle and/or its affiliates. All rights
reserved.

17. Differentiator: Reliability
• Decoupled architecture
– Individual processes can be restarted automatically
– Tolerance to network outages (configurable)
• Recovery
– Recovery ensures that no operations are skipped or duplicated after
failure of any kind
– Recovery of the Capture process is more involved than recovery the
Delivery process
– Although GoldenGate processes are completely decoupled, the
Delivery process must be aware of a recovery performed by the
Capture process or pump
