RE: Streams for one-time single source replication

How big is the entire database vs. the subset of schemas?

But, to answer your question, yes, DataGuard would work, but, it would get all the data. Now, of course, that is with a physical standby database. From what I understand, you could do a logical standby and only select specific schemas to keep in sync. I don't think I have a enough experience with those to give you too much direction though. The initial set up is very similar, but, the redo-apply process becomes the sql-apply process and leverages LogMiner to replicate only the objects you select. Hopefully, someone else can chime in and provide some insight to a logical standby approach.

Also, I don't want to discourage you from Steams altogether. I had originally assumed you would want the whole database kept in sync which would have made DataGuard the obvious choice for me.

Would this work for a logical copy? I can only have a subset of schemas cloned.

Thanks!
