1. How do you configure a unidirectional replication using GoldenGate? Unidirectional replication moves data from a source database to a target database in one direction only. Here’s the step-by-step configuration process: ✅ Source Side Configuration: ✅ Target Side Configuration: 2. What are the steps involved in setting up Integrated Extract? Integrated Extract is tightly coupled […]
1. How do you monitor GoldenGate processes and performance? Effective monitoring is vital for ensuring data replication health, low latency, and zero data loss. 🔹 Monitoring Tools and Methods: 2. What is the use of the lag and checkpoint commands? These commands help assess data latency and process recovery. 🔹 LAG Command: GGSCI> LAG EXTRACT […]
1. What is Conflict Detection and Resolution (CDR) in bidirectional replication? Conflict Detection and Resolution (CDR) is a mechanism in Oracle GoldenGate to handle data conflicts that arise in bidirectional (active-active) replication setups, where the same table is being updated at multiple sites simultaneously. 🧠 Why is CDR needed? In active-active replication, changes can occur […]
