Oracle Database: Duplicate Specific Tablespaces only

Oracle allows you to duplicate a database using specific tablespaces only, .

The command is same as the duplicate command 

Mention the tablespace comma separated names (highlighted in bold)
Ofcourse temp, system,sysaux, undo will be duplicated along

• rman run at the new database site
• target is source
• auxiliary is the new db
• list of tablespaces is comma seperated.
• if you want to skip a specific tablespace use 'skip <tablespace_name>' 

rman 
connect TARGET sys/passs@PROD;
connect AUXILIARY sys/pass@XDB1_STDBY;
run 
{
set newname for database to '+FRA';
DUPLICATE TARGET DATABASE 
  TO XDB
  FROM ACTIVE DATABASE
  TABLESPACE users
  NOFILENAMECHECK;

}

The highlight here is that oracle will internally check during duplicate that if the tablespaces are linked (dependent) or not.

You will have to ensure that static entries is present for the new database in the listener, as it will need to be shut down and started by the rman.
