Unix find command with mtime

So, how can you find files in Unix older than a specified number of days? The solution is the find command with the option mtime. mtime is the modified time of a file. It's the last time the data in the file was changed. Simple enough.

Find any file in /oback and all of its subdirectories that were last modified 1 day ago:

find /oback/ -mtime +1


Find any file in /oback, excluding subdirectories, that were last modified 2 days ago:

find /oback/* ! -name . -prune -type f -mtime 2

RMAN Restore vs. Recovery - what's the difference?

RESTORE is used to restore the datafiles from a backup. You can restore up to the time of the backup or a point before using SET UNTIL . You would lose any changes made to the database after the backup by performing only a RESTORE. RECOVER is used to roll the database forward after a RESTORE by applying the redo logs. In essence, RECOVER = RESTORE + redo logs. The following example assumes you have lost your control files and datafiles, but still have your redo logs. $ rman target / nocatalog RMAN> startup nomount; RMAN> restore controlfile from '/oback/controlfile'; RMAN> alter database mount; RMAN> restore database; RMAN> recover database; RMAN> alter database open resetlogs;
