1. Take a backup of the database and archived logs on the source system using RMAN. 2. Copy the backup files to the new target system using the same directory structure. 3. Restore the control file, SPFILE, and database files to the target system using RMAN, changing the data file locations and redo log file locations as needed. 4. Open the database with a resetlogs after restoring the database, control file, and archived redo logs from backup.

1. Restore RMAN to New Host

Steps On Source Database
**Most Of work will be done on target database
1- Get DBID By Using The below :
SQL > Select Db_id from v$database ;
Or
RMAN target /
2- Get the last SCN On Database since we will not have active redolog using the below
document :
SQL > select max(next_change#) from v$archived_log where archived = 'YES' group by
thread#;
Or Using RMAN:
RMAN> list backup of archivelog all;

2. Restore RMAN to New Host

3- Take Backup Using RMAN :
run {
allocate channel d1 type disk format 'YOUR-PATH/Database_%U;
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
BACKUP DATABASE PLUS ARCHIVELOG;
backup current controlfile format 'YOUR_PATH/controlfile_%U';
release channel c1;
release channel c2;
release channel c3;
}
Now move all generated backup file to the new host with the same directory for example if you
backup on folder /u01/app then on new host should be the same.

3. Restore RMAN to New Host

Steps On New Server
After copy file do the below steps:
1- export ORACLE_SID=SID_SAME_AS_PROD
RMAN TARGET /
RMAN > set dbid <as you get it from above query>;
RMAN > Startup nomount;
RMAN > restore spfile to pfile '/u01/app/oracle/oradata/orcl/initorcl.ora' from
autobackup;
RMAN> shutdown abort;
Now you have to edit SPFile ;
*.audit_file_dest=’LOCATION’
*.control_files=’LOCATION’
*.db_recovery_file_dest_size=Size
*.db_recovery_file_dest=’LOCATION’
*.diagnostic_dest=’LOCATION’
*.log_archive_dest_1='LOCATION=LOCATION’
*.local_listener='LISTENER_ORCL'

4. Restore RMAN to New Host
Osama Mustafa Page 4
RMAN> startup nomount pfile='/u01/app/oracle/oradata/orcl/initorcl.ora';
RMAN> restore controlfile from autobackup;
RMAN> alter database mount;
Note: now you have 2 options 1 - move the backup to same location on target server 2- Copy
Backup to any location but you need to use CATALOG Command check below :
RMAN> catalog start with 'Where You copy Backup';
You are almost Done, You have But before restore database you can move datafile to any
location using (all the below steps on RMAN ) But
Remember don't run the below yet:
SET NEWNAME FOR DATAFILE 1 TO '/u01/app/oracle/oradata/orcl/system01.dbf';
SET NEWNAME FOR DATAFILE 2 TO '/u01/app/oracle/oradata/orcl/sysaux01.dbf';
SET NEWNAME FOR DATAFILE 3 TO '/u01/app/oracle/oradata/orcl/undotbs01.dbf';
SET NEWNAME FOR DATAFILE 4 TO '/u01/app/oracle/oradata/orcl/users01.dbf';
SET NEWNAME FOR DATAFILE 5 TO '/u01/app/oracle/oradata/orcl/example01.dbf';
SET NEWNAME FOR DATAFILE 6 TO '/u01/app/oracle/oradata/orcl/test.dbf';
SET NEWNAME FOR DATAFILE 7 TO '/u01/app/oracle/oradata/orcl/dbfs01.dbf';
**Note: After TO: New Location.

5. Restore RMAN to New Host

SQL "ALTER DATABASE RENAME FILE ''/u03/app/oracle/oradata/orcl/redo/redo01.log'' TO
''/u01/app/oracle/oradata/orcl/redo/redo01.log'' ";
SQL "ALTER DATABASE RENAME FILE ''/u03/app/oracle/oradata/orcl/redo/redo02.log'' TO
''/u01/app/oracle/oradata/orcl/redo/redo02.log'' ";
SQL "ALTER DATABASE RENAME FILE ''/u03/app/oracle/oradata/orcl/redo/redo03.log'' TO
''/u01/app/oracle/oradata/orcl/redo/redo03.log'' ";
Are you still having SCN that we see it above :)
Ok Now you RMAN Script will looks like below
RUN {
SET NEWNAME FOR DATAFILE 1 TO '/u01/app/oracle/oradata/orcl/system01.dbf';
SET NEWNAME FOR DATAFILE 2 TO '/u01/app/oracle/oradata/orcl/sysaux01.dbf';
SET NEWNAME FOR DATAFILE 3 TO '/u01/app/oracle/oradata/orcl/undotbs01.dbf';
SET NEWNAME FOR DATAFILE 4 TO '/u01/app/oracle/oradata/orcl/users01.dbf';
SET NEWNAME FOR DATAFILE 5 TO '/u01/app/oracle/oradata/orcl/example01.dbf';
SET NEWNAME FOR DATAFILE 6 TO '/u01/app/oracle/oradata/orcl/test.dbf';
SET NEWNAME FOR DATAFILE 7 TO '/u01/app/oracle/oradata/orcl/dbfs01.dbf';
SQL "ALTER DATABASE RENAME FILE ''/u03/app/oracle/oradata/orcl/redo/redo01.log'' TO
''/u01/app/oracle/oradata/orcl/redo/redo01.log'' ";
SQL "ALTER DATABASE RENAME FILE ''/u03/app/oracle/oradata/orcl/redo/redo02.log'' TO
''/u01/app/oracle/oradata/orcl/redo/redo02.log'' ";
SQL "ALTER DATABASE RENAME FILE ''/u03/app/oracle/oradata/orcl/redo/redo03.log'' TO
''/u01/app/oracle/oradata/orcl/redo/redo03.log'' ";

6. Restore RMAN to New Host

SET UNTIL SCN <ABOVE_QUERY>;
ESTORE DATABASE;
