Answer 1

If you want to transfer large amounts of data (or small amounts, too) from one database to another, you should consider the tools that were specifically designed for such tasks.

First and foremost, look into data pump. It has a bit of a learning curve, though.

exp and imp (also by Oracle) are a bit easier to handle, but they're older and not nearly as powerful as data pump.

You might also want to look into the SQL*Plus copy command.
