Because redo logfile is used cyclically, there is no need to configure a large number of logs. You only need to have the appropriate number of log groups and the size of log files.

Yesterday, we performed a recovery drill after the RM-RF operation, without any backup. Today, before performing destructive operations, we made an RMAN full backup, and then deleted all database files online, including control files, data files, online log files, and archive files. Let's see how to restore the database. Because the current redo logfile is lost, data will be lost in this test, so it can be used as a case of Incomplete recovery. -- Lo
