Step by Step Restore RMAN to New Host Twitter : @osamaoracle

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;

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.

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'

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.

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'' ";
