Home -> Community -> Mailing Lists -> Oracle-L -> RE: Clone a database
Oops, my bad. I meant to say that exp/imp time is nearly linear and cloning
is constant regardless of the database size.

>From my point of view, exp/imp time is linear with the size of the database
and cloning is nearly linear except for the time to copy the files. For a
small database, I could do exp/imp much faster. I gave up creating test
databases using exp/imp on our largest production database when it grew past
50-gig. That was when I learned how to clone it.
I noticed that RMAN doesn't like you to clone your databases,
because it identifies databases by the DBID and that remains unchanged when
you clone the database. However, I notice RMAN has a feature to duplicate a
database and it does change the DBID then. I'm looking forward to learning
this technique. If anyone has found a pitfall with duplicate, please let me
know.

easier perhaps only if you have the exact same disk layouts and space available.
and certainly MUCH more time to create -- an import takes anywhere from 2-4 times as long as the export did.
