Like I said in a comment below, I'm no DBA and I'm still in a learning process.
Here's my scenario :
I have an Oracle server running a couple schemas (let' call it Source). What I would like to do is send a 1:1 copy of every objects to another Oracle server (let's call it Target) where there's already some objects that I need to preserve.
Ideally, I don't want to shutdown the Source server.
Also, I need to keep the already existing schemas of the Target server. So the new objects from Source need to co-exist on the Target server with the already existing objects. Maybe by using 2 instances that could be accomplish? I don't know, I'm just suggesting.
What could be the solutions to achieve that?
