Answer:
RMAN is an Oracle tool for taking the backup and recovering
the databases. You can copy, restore, and recover
datafiles, control files and archived redo logs (all 3
files or any one file). It has command line utility as well
as GUI-based Enterprise Manager Backup. Here we are
discussing the command line utility.
For example, we have TEST and PROD databases. Here TEST is
the catalog database and PROD is the target database for
which the backup has to be taken. You may loose your backup
if you have your catalog and target databases on the same
box and the box crashes .So it is always advisable to keep
a separate database for RMAN catalog .
Create two databases. One for RMAN catalog(Test) and one
target(PROD). Both the Databases should be archive log mode
(for security).
