Rman recovery from different machines

Note:

1. the directory structure of the source database and target database is the same

2. The target database only needs to install the ORACLE software (but the directory specified in the parameter file must be created)

3. Back up data files, parameter files, control files, password files, and archive logs of the source database.

 

1. source database backup

 

Automatic Backup of parameter files and Control Files

Configure controlfile autobackup on;
Configure controlfile autobackup format for device type disk to '/home/oracle/rmanback/level_cont_spfile _ % F ';

Back up databases and archive logs

Backup incremental level 0 database format'/home/oracle/rmanback/level0 _ % d _ % s _ % p _ % u. bak'
Plus archivelog format'/home/oracle/rmanback/level0arclog _ % d _ % s _ % p _ % u. bak 'delete all input;

2. Copy the backup file to the same path of the target database.

 

Scp level * 192.170.100.12:/home/oracle/rmanback

3. Start the database to nomount

4. Restore the parameter file

 

RMAN> restore spfile to pfile '/home/u01/app/oracle/product/11.2.0/db_1/dbs/initghsjdb. ora' from '/home/oracle/rmanback/level_cont_spfile_c-1442539879-20150107-00'
2>;

RMAN> SQL 'create spfile from pfile ';

SQL statement: create spfile from pfile

5. Create the specified path in the parameter file

 

Mkdir-p admin/ghsjdb/adump
Mkdir-p oradata/ghsjdb
Mkdir-p fast_recovery_area/ghsjdb
Mkdir archivelog
6. Restart to nomount

 

RMAN> startup force nomount;

7. Restore Control File

 

RMAN> restore controlfile from '/home/oracle/rmanback/back ';

Starting restore at 07-JAN-15
Using target database control file instead of recovery catalog
Allocated channel: ORA_DISK_1
Channel ORA_DISK_1: SID = 1141 device type = DISK

Output file name =/home/u01/app/oracle/fast_recovery_area/ghsjdb/control02.ctl
Finished restore at 07-JAN-15

8. Start the database to the mount status.

 

RMAN> alter database mount;

Database mounted
Released channel: ORA_DISK_1

9. Because the Backup Paths of the target database and the source database are the same, you do not need to register them in the control file again.

 

RMAN> catalog start with '/home/oracle/rmanback ';

 

10. restore database;

 

RMAN> restore database;
