In the Oracle world, there are three types of data: undo, redo, and data.

Instance recovery objective: to ensure data loss in buffer cache and Database Consistency when the database failsMedia

Label:Online redo log files are used to cycle through all operations of the Oracle database and are almost always read-write, so it is meaningless to back up the online redo log files at some point in time, and to restore them at all. The Rman backup does not have the ability to back up the online redo log at all, and not only Rman, but all backup software does not have the idea of backing up the online redo log file. Therefore, the recovery of the da

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.
