RMAN has evolved since Oracle 8i and includes new features in Oracle 12c that help reduce downtime. In 12c, a container database can include pluggable databases. RMAN supports backup and recovery of container databases and individual pluggable databases. New features in 12c include the SYSBACKUP privilege which allows backups without granting full SYSDBA privileges, and support for multitenant container databases and pluggable databases.

RMAN IN 12c: THE NEXT GENERATION
Gustavo René Antúnez, The Pythian Group
ABSTRACT
TARGET AUDIENCE
This paper will be beneficial for anyone who is beginning to use Oracle’s Recovery Manager and for those who are already
using it, but want to understand the several new features of RMAN in Oracle 12c.
EXECUTIVE SUMMARY
RMAN IN 12C: THE NEXT GENERATION
The new generation of Oracle’s popular database has been designed for the Cloud and will enable you to make more
efficient use your IT resources while continuing to improve your users’ service levels. With this, there are enhancements and
new features, which will make it easier for customers to take advantage of the Cloud.
In here we will discuss several of these new features, but only specific to Oracle’s backup and recovery utility RMAN.
The first thing that we have to do, is understand that in Oracle 12c, a new concept is introduced, which are Pluggable
and Container databases.
WHAT IS A CONTAINER AND A PLUGGABLE DATABASE?
A container database (CDB) is an Oracle database that includes zero, one, or many customer-created Containers or
Pluggable Databases.
The CDB has:
• One ROOT container (CDB$ROOT) containing SYSTEM, SYSAUX, UNDO, and TEMP tablespaces,
Controlfiles and Redologs.
• One SEED container (PDB$SEED) containing SYSTEM, SYSAUX, TEMP, EXAMPLE tablespaces, used
as a template to create new PDBs
Oracle Recovery Manager (Oracle RMAN) has evolved since being released in version 8i. With the newest version
of Oracle 12c, RMAN has great new features that will allow you to reduce your down time in case of a disaster. In this
session paper you will learn about the new features that were introduced in Oracle 12c and how can you take advantage of
them from the first day you upgrade to this version.
Learner will be able to:
• Understand what is RMAN and how has it evolved along versions of Oracle
• Obtain the knowledge of the newest features of RMAN in Oracle Database 12c and how to apply them.
• Provide examples of backup and recovery solutions with RMAN 12c
• How RMAN and EM 12c are moving hand in hand with DBaaS

A pluggable Database (PDB) is a user-created container holding the data and code for your specific applications. A
PDB:
• Has SYSTEM, SYSAUX, and TEMP tablespaces.
• Contains any number of other user created tablespaces.
• Writes to the container UNDO tablespace, controlfiles and redologs.
• Undo and redo is annotated with details of the PDB that they belong to.
GENERAL BACKUP AND RECOVERY–OVERVIEW OF RMAN
Now we have to understand what RMAN is and how RMAN works. Recovery Manager or better known as RMAN,
is an Oracle client utility that is installed with the Enterprise or Standard edition, you can also find it with the Admin option
when installing the Oracle Client.
By being a client side utility, it allows you to use one RMAN executable version to backup current and previous versions
of the Oracle Database; there are some restrictions to this though, which can be verified in MOS document RMAN
Compatibility Matrix [ID 73431.1].
This RMAN executable uses a file called recover.bsq, this file is located in $ORACLE_HOME/rdbms/admin, basically
what the executable does, is to interpret the commands you give it, direct server sessions to execute those commands, and
record its activity in the TARGET database control file that is being backed up.
There are two main SYS packages that do the work of backup and recovery, which are DBMS_RCVMAN, this has the
procedures which list your database incarnations, the set until time recovery window, list your backups, to name a few, and
DBMS_BACKUP_RESTORE , which as you might have guessed is the one who does the backup and recovery operations,
like create the control file snapshot , backup the datafiles, backup the spfile to name some.
As mentioned above, the way that the RMAN client directs the server sessions to execute the commands are through
channels, a channel represents one stream of data to a device, and corresponds to one database server session. The channel
reads data into PGA memory, processes it, and writes it to the output device.
The work of each channel, whether of type disk or System Backup Tape (SBT), is subdivided into the following distinct
phases:
• Read Phase
A channel reads blocks from disk into input I/O buffers. The allocation of these buffers depends on the number of
datafiles being read simultaneously from disk and written to the same backup piece. One way to control the numbers of
files is the backup parameter FILESPERSET
• Copy Phase
A channel copies blocks from input buffers to output buffers and performs additional processing on the blocks, like
the validation of the data blocks, as it verifies that it's not backing up corrupt data blocks, it's also the phase where it does
the binary compression and the backup encryption
• Write Phase
A channel writes the blocks from output buffers to storage media. The write phase can be either to SBT or to disk,
and these are mutually exclusive, meaning you write to one or the other, not both.
As you can see by the phases above, and what distinguishes RMAN from any other method, is that the backup is at the
block level, as to the user managed backups, it brings great advantages, as it wont have to backup empty blocks.

WHAT DO YOU NEED TO BACKUP?
When you consider on using Oracle’s RMAN utility, there are files that are critical to backup so that you can be able
to restore and recover your database in case a disaster were to occur:
• Data files
• Control files
• Archived Redo logs (If Database running in Archive Log mode)
But let’s say a full on disaster were to happen, in which not only you lose your database, you lose your site or your
server, you need some additional files are needed so that you can have your data available as soon as possible:
• Parameter File (pfile1 or spfile)
• Block Change Tracking File1
• ORACLE_HOME/GRID_HOME1
• tnsnames.ora / listener.ora/ sqlnet.ora1
These additional files are not critical in RMAN to be backed up, but are very important in case a full disaster were to
occur, as if you were not to have a backup of these, you would need to rebuild your ORACLE_HOME / GRID_HOME
from scratch, taking you more time to have the data available to your client.
1These files are not backed up with Oracle’s RMAN utility, you need to use a distinct method to back up these types of files.
ORACLE RMAN 12C NEWEST FEATURES
A) SYSBACKUP
PRIVILEGE
In Oracle 12c the SYSBACKUP privilege was introduced, this privilege allows a user to perform backup and recovery
operations RMAN.
You can connect with the “as sysbackup” or if using a password, a password file needs to be created or in place.
There are also special OS System Groups (OSDBA or OSBACKUPDBA), which allow you to connect to your database as a
privilege user without the need of an additional password and perform your backups. One thing to keep in mind for windows
environments, you need to have in your sqlnet.ora the next entry: SQLNET.AUTHENTICATION_SERVICES=(NTS).
OS System Group Name UNIX/Linux Windows
OSDBA dba ORA_DBA (for all Oracle homes)
ORA_HOMENAME_DBA (for each specific Oracle home)
OSBACKUPDBA backupdba ORA_HOMENAME_SYSBACKUP

But what is most important about this is that it allows you to not grant the SYSDBA privilege to the user that runs
and administers your backups, so that user will no longer be able to SELECT/INSERT/UPDATE/DELETE ANY TABLE.
[oracle@oracleenespanol2 Desktop]$ rman target '"/ as sysbackup"'

B) SUPPORT
FOR
MULTITENANT
CONTAINER
DATABASES
AND
PLUGGABLE
DATABASES
With the RMAN utility it provides full backup and recovery support, not only for your container database, but also
for one or all of your pluggable databases. With this in mind the first thing that you want to do is identify how your
database is composed. You can do this with the report schema command. When you use it in a container level, you can see
that your pluggable databases files are preceded with the name of it. When you use it at the pluggable level, you will only
see the files that belong to that particular database.

Backing up your databases in 12c does not differ much as with previous versions as long as you understand the
hierarchy that persists with this version. When backing up the container database (CDB1), it will backup your root and all of
your pluggable databases files. With this type of backup it will allow you to recover one or all of your pluggable databases as
well as your container database.

When you only connect to your pluggable (PDB1), you can also make a backup of this database, but it will only allow you to
recover that particular database. One thing to keep in mind, is that if you include your archivelogs when backing up your
database, it doesn’t do an archivelog switch, this will only happen at the container level, when you do it at a pluggable level, it
will tell you that there are no archivelogs in the repository.

In this version, Oracle recommends that you frequently backup your root database as it contains critical metadata for
the whole CDB, while each PDB might fall into it’s own SLA’s depending on the lifecycle of it or of your business needs. The
way to backup your root is connecting to the target and issue the backup database root command.

As with previous versions of RMAN, one way to know what backups you have is with the command LIST, and with
the report has been added the record of Container ID, which will allow you to identify to which database your backup belongs
to, keeping in mind that your container database will not have a Container ID reported, it is assumed that is the ID number 1.

C) Recovering
Tables
and
Table
Partitions
from
RMAN
Backups
In 12c, RMAN allows you to recover one or more tables/table partitions to a specific point in time without affecting the
rest of your objects in your container or pluggable databases and without the need to restore the entire containing tablespace.
Before you restore your table, the following prerequisites need to be met:
• The target database must be in read-write mode.
• The target database must be in ARCHIVELOG mode.
• You must have RMAN backups of the tables or table partitions as they existed at the point in time to which you want
recover these objects.
• You need to have at least 1 Gigabyte extra in memory for the auxiliary database.
• You need to have the physical disk space to hold the SYSTEM/SYSAUX/UNDO/TEMP, the physical disk space
that was occupied by the table as well as the space of the datapump export that is generated.
• As of version 12.1, you need to use a SERVICE_NAME when connecting to RMAN or it will fail.
• You can use SCN, Time or a Log Sequence number
• Tables and table partitions on standby databases cannot be recovered.
• Tables with named NOT NULL constraints cannot be recovered with the REMAP option.
In the example below, we will restore the table TEST.RENE, with the command RECOVER TABLE, that was logically
corrupted and remap the table to TEST.RENE_RCV, we are also running this from the container database CDB1, and so we
have to specify that the table belongs to the pluggable database PDB1. Several lines have been removed to help readability.

D) SQL
Interface
Improvements
In RMAN 12c, you can now execute SQL commands and PL/SQL procedures from the RMAN command line without
prefixing the command with the SQL keyword. This includes select statements as well as the describe command which offers
the same functionality as the SQL*plus describe command. You no longer need to enclose the SQL command in quotes,
which greatly simplifies the syntax when the SQL command itself requires quotation marks.

E) Active
Database
Duplication
Improvements
In Oracle 11g, Active duplicate was introduced; it is defined as a duplicate database that is created over a network
without restoring backups of the target database. This technique is an alternative to backup-based duplication.
In 11g this method used a push-based method, in which from the target database would send full image copies over
the network to the auxiliary database, using the target channels.

13 | P a g e “RMAN IN 12C: THE NEXT GENERATION”
White Paper
In 12c, the default method is the pull-based method; RMAN sends datafile data as backupsets to the auxiliary
instance and from within that instance, restores the datafiles. RMAN will create a new backupset on the source and directly
transmit (through Sql*net) to the auxiliary.
There are several factors that determine whether Backup Sets or Image Copies are used:
• RMAN will only use image copies when no auxiliary channels are allocated or when the number of allocated
channels is less than the number of channels.
• RMAN will use Backup Sets when the connection to the target database is established using a net service name
and any one of the following conditions is satisfied:
o The DUPLICATE ... FROM ACTIVE DATABASE command contains either the USING
BACKUPSET, USING COMPRESSED BACKUPSET, or SECTION SIZE clause.
o The number of auxiliary channels allocated is equal to or greater than the number of target channels
allocated.

Another enhancement that was introduced in 12c is that you can now specify that you don’t want the auxiliary
database to be opened when the duplication finishes (NOOPEN option). This is very helpful in environments, like Peoplesoft,
where is critical to not open a database after its been duplicated, as it will start running scripts to the production environment
and can cause errors in you application.

EM12C AND RMAN 12C
Oracle Enterprise Manager 12c provides you with an interface where you can manage most of RMAN’s features via a
GUI interface. Using EM 12c also removes the need to continuously maintain RMAN scripts and crontab jobs. Another great
advantage of using EM 12c for RMAN is for reporting purposes as you can view a more friendly report of your backups, that
are not as cryptic as the LIST BACKUP command.
It is imperative to know that to access the RMAN features in EM 12c you need to have a credentialed OS account, as
it will be a needed requirement for you to setup your backups with this tool.

To access the RMAN features in EM 12cR3, you need to login and go to the following location, Targets à
DatabasesàDB_NAMEàAvailabilityàBackup&Recovery. There you fill find all the Backup And Recovery Options you
have in you hand with EM12cR3
A) Scheduling
a
Full
Backup
To run a full backup within EM12c, you need to go to AvailabilityàBackup&RecoveryàSchedule Backup… Where
you will have the range of backup types that you want to run, either Oracle-Suggested Backup or Customized Backup. In this
document we will only explore the Customized Backup. With the Customized Backup you are given the option to select the
type of objects you want to backup
• Whole Database
• Container Database Root
• Pluggable Databases
• Tablespaces
• Datafiles
• Archived Logs
• All Recovery Files on Disk
Now you will have the Options for your backup, where you will decide if you want to run a full or incremental
backup, hot or cold backup as well as backup your Archived Redo Logs

In the settings section, you can define if your backup will reside in Disk or you will use a MML, as well were you can
view the RMAN settings for your database
In the third step of this process, you will set the schedule for your backups
• One Time (Immediately). - This is a one time only execution of your backup and will start as soon as you submit the
job.
• One Time (Later). - This is a one time only execution of your backup and will start at the specified date.
• Repeating. – This job will run at the desired start time, will repeat through out the defined frequency and it can be
indefinite or end at a specified date.

C) Groups
Backups
One of the greatest advantages of using EM12c, is the feature of setting up and schedule backups for a whole set of
groups. This is not only available for 12c databases, it is available for 10.2 and higher versions in EM12cR3. Taking advantage
of setting up the following only once per group:
• Backup Storage Settings
• Recovery Catalog Settings
• Backup Type
• Frequency
If you are using Administrative Groups, this will make the task even easier, as you would setup the Backup
Configuration and Schedule Backup for each of your administrative group and every time you add a new target to an
administrative group, it will automatically use these properties, without worrying about them.
To use this, you will need to have a group or an administrative group created, for this example, I have an admistrative
group defined by Lifecycle StatusàLocation, and will do the setup for the group “Prod-Mexi-Grp”
To access this group, in EM12cR3, you need to go to TargetsàGroupsàViewàExpand All and click on “Prod-
Mexi-Grp”. Once you have accessed the Prod-Mexi-Grp page, you will see several dashboards that will provide you the Status,
general Information, Incidents Job Activities, etc…
To start the group backup setup, you need to define the backup configuration first for this group; you need to go to
“Prod-Mexi-Grp”àGroupàBackup Configurations

Backup Procedure, you hit submit and you will see an informational banner that the job was submitted.
You can click on the link of the submitted procedure and it will take you to a detail page, where you will see the status
of all your backups, as well as the logs of each of the steps that were submitted. Another way to see the jobs that have been
run for this group is to go to EnterpriseàProvisioning and Patching àProcedure ActivityàAdvanced

incorporate EM12c into your backup strategy, you can simplify your backup administration tasks, especially when you have
correctly setup your administrative groups and you have several hundred databases within those groups.
