1. Copy or remotely mount the backupset folder from the source server to the target server

2. On the target server, export ORACLE_SID as same as the source database and run "rman target /"

3. Restore spfile from backup:

RMAN> startup nomount;

startup failed: ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initorcl01.ora'

starting Oracle instance without parameter file for retrieval of spfile

Finished restore at 27-OCT-14

4. Open another ssh session, export ORACLE_SID and run "sqlplus / as sysdba" and create pfile from spfile:

[oracle@localhost dbs]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Mon Oct 27 10:34:57 2014

Copyright (c) 1982, 2009, Oracle. All rights reserved.

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> create pfile from spfile;

File created.

SQL> exit

5. Review the pfile just created and mkdir all the file dests:

[oracle@localhost dbs]$ cat initorcl01.ora
orcl01.__db_cache_size=188743680
orcl01.__java_pool_size=4194304
orcl01.__large_pool_size=4194304

[oracle@localhost dbs]$ mkdir -p /u01/app/oracle/admin/orcl01/adump

[oracle@localhost dbs]$ mkdir -p /u01/app/oracle/oradata/orcl01

[oracle@localhost dbs]$ mkdir -p /u01/app/oracle/flash_recovery_area/orcl01

6. In the RMAN session, restore the control files:

RMAN> restore controlfile from '/u01/app/remote/flash_recovery_area/ORCL01/backupset/2014_10_01/o1_mf_ncsn1_TAG20141001T011809_b2q3ojl8_.bkp';

7. Restart database in mount mode. You cannot directly alter database mount because the spfile has been restored:

RMAN> alter database mount;

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of alter db command at 10/27/2014 10:35:35
ORA-01103: database name 'ORCL01' in control file is not 'DUMMY'

RMAN> shutdown immediate;

Oracle instance shut down

RMAN> startup mount;

8. Catalog the backupsets:

RMAN> catalog start with '/u01/app/remote/flash_recovery_area/ORCL01/backupset/2014_10_01';

9. In the sqlplus session, check v$datafile and v$logfile and mkdir the directories.

SQL> select file#,name from v$datafile;

FILE#
----------
NAME
--------------------------------------------------------------------------------
1
/u01/app/oracle/oradata/orcl01/system01.dbf

2
/u01/app/oracle/oradata/orcl01/sysaux01.dbf

3
/u01/app/oracle/oradata/orcl01/undotbs01.dbf

FILE#
----------
NAME
--------------------------------------------------------------------------------
4
/u01/app/oracle/oradata/orcl01/user01.dbf

5
/u01/app/oracle/oradata/orcl01/example01.dbf

6
/u01/app/oracle/oradata/orcl01/index01

6 rows selected.

SQL> select member from v$logfile;

MEMBER
----------------------------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl01/redo03.log
/u01/app/oracle/oradata/orcl01/redo02.log
/u01/app/oracle/oradata/orcl01/redo01.log

In this case, /u01/app/oracle/oradata/orcl01 has been created at step 5.

10. In RMAN session, restore database, recover database and open database with resetlogs option

RMAN> restore database;

...

RMAN> recover database;

...

RMAN> alter database open resetlogs;

...

P.S.: if you want to restore datafiles to a different path, in step 10:

RMAN> run{
2> set newname for datafile 1 to '/u01/app/oracle/oradata/newpath/system01.dbf';

3> restore database;
4> switch datafile all;
5> recover database;
6> }
