In my previous post I have analyzed what happens if you would like to prevent archive logs from deletion so that they can be further processed by Oracle GoldenGate. I have assumed that it would work the same if the RMAN recovery catalog was being used. Lets find out what happens.

This mechanism is supported both in Classic and Integrated Extract mode. Although the latter one offers more functionality and control.
