Oracle goldengate (Ogg) supports real-time transaction Change Data Capture, conversion, and transmission in a diverse and complex IT architecture. Data Processing and exchange are measured in transactions and support heterogeneous platforms, for example, DB2 and MSSQL Golden Gate supports two major types of solutions for different business needs: ● High availability and Disaster Tolerance Solutions ● Real

blocks through the TCP/IP protocol, which is also recommended. The pump process is essentially a special form of extract process. If the trail file is not used, the extract process directly delivers the data to the target end to generate a remote trail file after extracting the data. ÜCollector: CollectorThe process corresponds to the pump process and runs on the target end. This process does not need to be too concerned, because we do not need to configure it during actual operations, so it i

Golden Gate (OGG for short) provides real-time capturing, conversion, and delivery of transaction data in heterogeneous environments. OGG supports the following heterogeneous environments: OGG features: Small impact on the production system: reads transaction logs in real time to replicate large transaction volumes in real time with low resource usage Copies data in transaction units to ensure transac

I. Initialization instructions During Gg implementation, Initialization is an important task, especially when there is a large amount of data to be initialized and the system is 7x24. For static initialization, the business will be stopped and the data on the DB will not change. At this time, we can use expdp/impdp or dblink to synchronize the basic data, start the relevant Gg synchronization process. However, if zero downtime is required, DB transactions will continue. You can use the followin
