Golden Gate realtime replication basic question
Is this doable in GoldenGate(GG)?


The Map or Table parameter can be used to select Table, depending on whether to apply in Extract or in Replicat.

The Cols and ColsEXCEPT attributes of the Table parameter can be used for Columns selection. 

I believe that the Oracle's official documentation is good link to create the solution.

Here are some.
