We have a DB server that hosts  a DB, we need to use RMAN 11g active duplication to duplicate the DB to a new host;
Can we duplicate this DB to the new host and end up with a database(on the new host) that has the same db_name and instance_name.
For RMAN 11g active duplication I know that the newly created DB will have a new DBID;
but we want to also to keep the same db_name and sid_name.
Is this possible?

thanks,

I've never done it but cannot think of a reason you cannot use the same names on a different server as long as you understand the potential problems having two databases with the same name.

If there some reason you think you might not be able to do this?

I read a little about active duplication and it sort of implies you get a database with the same name.

There is a reference in the docs for DB_NAME but only when sharing ORALCE_HOMES:

http://download.oracle.com/docs/cd/B28359_01/backup.111/b28270/rcmdupdb.htm

DB_NAME
 

The same name used in the DUPLICATE command.
 
The DB_NAME setting for the duplicate database must be unique among databases in its Oracle home.

Hi,

RMAN duplication (active or not) implies a new DBID. But there's no restriction about what your db name is. It works fine even if you go for the same name (tested on 11.2/linux).

Cheers,
