ROAD-2-ORACLE : RMAN backup scenario, How to Create New database using RMAN

This Documents also provide by Mr. Uzzal Basak :-)

How to Create New database using RMAN backup scenario:

I have two database servers, 1 is my production db server and other one is backup testing db server. in backup testing server i have installed only oracle binaries.(server) haven't configured any databases using dbca. ;)
connect to rman of production db and take the backup of controlfile/datafile/archivelogs.

bash-3.2$ mkdir rman_backup

bash-3.2$ cd rman_backup/

bash-3.2$ pwd

/export/home/oracle/rman_backup

SQL> shutdown immediate

Database closed.

Database dismounted.

ORACLE instance shut down.

SQL> startup mount

now backup database full
rman> run {
allocate channel d1 type disk;
allocate channel d2 type disk;
backup
format '/export/home/oracle/rman_backup/%U.bkp'
database plus archivelog;
release channel d1;
release channel d2;
}

--------------------------------------------------------------------
now get the paths of backup files taken

oracle$ sqlplus / as sysdba

sql>select name from v$datafile;

sql>select member from v$logfile;

sql>select name from v$controlfile;

sql>show parameter dump_dest

copy them to a textpad bcz we want to create same directories in
other server.

----------------------------------------------------------------------

now connect to the backup testing server

create directories for files like backupset and dumpset

oracle$ cd $oracle_home
oracle$ mkdir oradata
oracle$ cd oradata
oracle$ mkdir orcl

--------------------------------------------------------------------
now get the paths of backup files taken
oracle$ sqlplus / as sysdba
sql>select name from v$datafile;
sql>select member from v$logfile;
sql>select name from v$controlfile;
sql>show parameter dump_dest
copy them to a textpad bcz we want to create same directories in
other server.
----------------------------------------------------------------------
now connect to the backup testing server
create directories for files like backupset and dumpset

oracle$ cd $oracle_home
oracle$ mkdir oradata
oracle$ cd oradata
oracle$ mkdir orcl

oracle$ /export/home/oracle/admin/orcl
oracle$ mkdir orcl
oracle$ cd orcl
oracle$ mkdir adump bdump cdump udump
oracle$ mkdir rman_backup
----------------------------------------------
now connect to the prod db and copy all the backup files to
relevant location.
archivelogs,controlfile,datafile to rman_backup using scp command

----------------------------

now connect to backup server

first step is to restore spfile

oracle$ export oracle_sid=orcl

----------------------------
now connect to backup server
first step is to restore spfile
oracle$ export oracle_sid=orcl
oracle$ rman target /
start the database in nomount mode using dumy parameter file
rman> startup nomount
RMAN> restore controlfile from '/export/home/oracle/rman_backup/ORCL/autobackup/2014_07_29/o1_mf_s_854236524_9xhr0gkv_.bkp';
RMAN> restore controlfile from '/export/home/oracle/rman_backup/ORCL/autobackup/2014_07_29/o1_mf_s_854236524_9xhr0gkv_.bkp';

now login to rman and restore the database
rman target /
restore database
rman> restore database;
if this fails catalog datafiles
rman> catalog start with '/u01/app/oracle/flash_recovery_area/backupset/2011-02-02';
rman> restore database;
recover database using logfiles
rman> recover database
it fails, so issue below
