step1 ：backup whole db using rman tools include crontrol files and archive log ;

step2: copy backup sets on same to primary host location;

step3: vi dupliate1.rcv

run{
SET NEWNAME FOR DATAFILE 1 to '/mnt/disk1/oracle/oradata/orcl/system01.dbf';
SET NEWNAME FOR DATAFILE 2 to '/mnt/disk1/oracle/oradata/orcl/undotbs01.dbf';
SET NEWNAME FOR DATAFILE 3 to '/mnt/disk1/oracle/oradata/orcl/sysaux01.dbf';
SET NEWNAME FOR DATAFILE 4 to '/mnt/disk1/oracle/oradata/orcl/users01.dbf';
SET NEWNAME FOR TEMPFILE 1 to '/mnt/disk1/oracle/oradata/orcl/temp01.dbf';
DUPLICATE TARGET DATABASE to orcl
LOGFILE
    '/mnt/disk1/oracle/oradata/orcl/redo01.log' SIZE 4096K,
    '/mnt/disk1/oracle/oradata/orcl/redo02.log' SIZE 4096K,
    '/mnt/disk1/oracle/oradata/orcl/redo03.log' SIZE 4096K;
}

step4:

rman:@dupliate1.rcv

RMAN> run{

5> SET NEWNAME FOR DATAFILE 4 to '/mnt/disk1/oracle/oradata/orcl/users01.dbf';
6> SET NEWNAME FOR TEMPFILE 1 to '/mnt/disk1/oracle/oradata/orcl/temp01.dbf';
