Configuring RMAN for Oracle Secure Backup
Learning Objective
After completing this topic, you should be able to
recognize how to configure RMAN for OSB
1. Integrated dik and tape backup
Oracle Database 10g(and later) has a Flash Recovery Area, abbreviated as FRA, which
is a unified disk storage location for all database recoveryrelated files! R"A# $anages
the disk s%ace in FRA! &ith FRA and Oracle 'ecure acku%, also known as O', you
can easily de%loy a co$%rehensive disk and ta%e backu% and recovery strategy for your
Oracle Databases!

considerations for the Oracle 11gDatabase used in this course!
y %utting R"A# in control of your backu% and restore o%erations, you si$%lify your
availabilityrelated %rocesses! ou have the $ost effective restore %rocess because
R"A# auto$atically restores fro$ the best backu% source (which can be a disk or ta%e)!
*f the $ost recent backu% is not available, R"A# continues with a %revious backu%! +his
failover can be fro$ a disk to a ta%e! *t does not reuire any user intervention!
+o back u% FRA to ta%e with O', you issue the R"A# co$$and BACKUPRECOVERY
AREA!
-sing this disktota%e backu% $ethod (instead of %erfor$ing a se%arate backu% of the
%roduction database to ta%e) %rovides a few advantages.
*t saves ta%e resources with o%ti$i/ed backu%s of FRA! *t eli$inates unnecessary backu% of f iles,
which are already on ta%es!
*t enables R"A# to utili/e better restore intelligence, first fro$ disks, and then fro$ ta%es, as
needed! Otherwise, R"A# uses the $ost recent backu% regardless of the storage $edia!

*t reduces *O (i$%ortant for %roduction databases) because FRA uses a se%arate disk grou%!
y defining retention %eriods within R"A#, a co$bination of disk and ta%e backu%s is
used to $eet your recovery reuire$ents! &hen using FRA and O', the reco$$ended
R"A# retention %olicy is the userdefined RECOVERYWINDOWo%tion! +his $eans, you
define a %eriod of ti$e within which %ointinti$e recovery $ust be %ossible!
#rap$ic
In this example, the period of time within which point-in-time recovery must be
possible is specified as seven days.
&hen defining the R"A# recovery window, also consider the
base retention on recovery needs
si/e of FRA based on the desired disk recovery ca%ability, and
schedule disk and ta%e backu%s through R"A# or nter%rise "anager, also known as "
-sing the R"A# DELETEOBSOLETEco$$and, you delete obsolete files on the disk and
notify O' of the backu% %ieces that are no longer needed!
*f your recovery %lan allows for restoration fro$ a disk for a certain nu$ber of hours each
day, FRA should be of sufficient si/e to hold the recoveryrelated files for this ti$e %eriod!
+he a$ount of ti$e backu%s that re$ain within FRA is deter$ined by the a$ount of
available disk s%ace, not by a s%ecific ti$e setting!
+here are five ste%s in the basic %rocess flow of R"A# and O'.
1! R"A# initiates backu% and %asses the database backu% storage selector to O'! *f R"A# is
started fro$ the " interface, then you $ust configure the ad$inistrative server in " (a one
ti$e task)!
2! O' creates the backu% 3ob! +y%ically, the O' na$es%ace associated with the O' user of the current
session is used!
4! O' e5ecutes the 3ob (transfers data fro$ client to $edia)!
6! O' u%dates its own catalog!
7! R"A# u%dates its re%ository!
O' has been integrated with " (Database 8ontrol and 9rid 8ontrol)! *t can be
accessed through the Availability %age!
