Re: Golden Gate Replication from a Physical Standby

I have done a few zero down time migration using OGG. OK, they were not zero minute but it took me probably 5 minutes to migrate for example a 5TB database from 9.2.0.8 to 11.2.0.4.

The extract was against primary database, in you case where you want to extract from a standby database you can use ALO as Job suggested if you pretend using classic extract but if your source is RAC I would recommened you to use integrated extract, in that case ALO is not supported but you can configure Downstream Mining which does support Integrated Extract.
