I assume you have ruled out RMAN DUPLICATE?

Short of that:
create a duplicate database on the destination with the same file names
shutdown the source
ftp the datafiles over
startup both


If you are using *nix, you can compress the datafiles before you ftp them and save on transfer time.

You can probably to it all in-stream with pipes so you don't have to store the compressed files on disk to save some write times.

Hi,

In 11g R2 we can even clone the database actively

Active Database Duplication   ==>  New feature.


DUPLICATE DATABASE TO <new_dbname> FROM ACTIVE DATABASE  SPFILE  NOFILENAMECHECK;

See the link for Active database duplication

http://www.oracle-base.com/articles/11g/duplicate-database-using-rman-11gr2.php



We can perform this based on scn we can clone the database actively to other location.




Thanks,
Ramesh G
