Once these rules are in place, GoldenGate processes scan the redo data for any records for the replicated tables. Most of the time, these changes are intended and generated by some application. However, sometimes some data updates are performed in the source environment by mistake and you would ideally not want them to be replicated to the target environment. In such scenarios, the administrator might want to roll back the changes performed. You can perform such tasks using the latest database technologies, for example, flashback. However, it is very difficult to roll back only a set of transactions from the database especially when you have applied complex filtering in the GoldenGate configuration. In such cases, you need another approach which will reverse the changes that were applied using GoldenGate. GoldenGate provides a reverse utility using...
