Introduction to GoldenGate OracleGolden Gate is a log-based copy and backup software for structured data. It parses Source Database online logs or archive logs to obtain incremental data changes and then applies these changes to TargetDatabase, to synchronize the source and target database
abbreviation for goldengate Software command Interface, which provides a very rich set of commands to perform various operations on goldengate, such as creating, modifying, monitoring goldengate processes, and so on.Commit Sequence NumberThe previous article has repeatedly mentioned that Goldengate is to ensure the integrity of the data in the transaction unit, then How does goldengate recognize a business? here is the Commit Sequence number (CSN).

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
