Note: 1 The experiment environment is the same platform, in the same byte order, in the same version. The directory structure of the source and target machines is the same. 2. You only need to install the oracle database software on the target machine. 3. Use backup for the first time to restore the test environment, copy the backup from the source machine to the target machine, and register it in the control file. Goodbye to restore the test.
One copy parameter file backup, control file backup, data file backup, and archive backup to the new host
1. Connect rman to the source database[Oracle @ oracle dbs] $ rman target/Recovery Manager: Release 10.2.0.1.0-Production on Tue Dec 11 19:02:05 2012 Copyright (c) 1982,200 5, Oracle. all rights reserved. connected to target database: CRM (DBID = 3601019238) RMAN>
2. List parameter file backup, control file backup, data file backup, and archive backup name respectively.
The parameter file backup is as follows:

The archive backups are listed as follows:RMAN> list backup of archivelog all; note: the archived backup should include the current online log file.
3 copy these backups to the new host
2. Restore parameter files and Control Files
1. Configure ORACLE_SID on the new hostExport ORACLE_SID = CRM
2. Initiate the rman connection on the new host[Oracle @ oracle dbs] $ rman target/Recovery Manager: Release 10.2.0.1.0-Production on Mon Dec 10 05:49:11 2012 Copyright (c) 1982,200 5, Oracle. all rights reserved. connected to target database (not started)

Conclusion: At this point, the database has been restored. You only need to back up, archive, or archive the data on the source machine and copy the data to the target machine, register the backup (catalog start with '/backup/') in the control file and then perform restoration.
