I have a question about Flashback Data Archive tables in Goldengate replication. Are these tables usually excluded in an extract like “TABLEEXCLUDE .SYS_FBA_*”?
What is the approach for replicating and initial load of Flash Back Data Archive tables?
Here is my problem. I exported a user schema using Oracle DataPump, imported into destination database. GoldenGate abended saying some tables dont exist on dest. I checked tables and there were about 200 tables that were not exported because they are FBDA tables and DataPump just ignores them. So, I recreated them on source with scripts.
So, how is this done? Source and destination have their own FBDA and these tables should not be neither recreated with scripts on dest or replicated? Or they have to be replicated with contents?
