RMANThe following sections explain how RMAN works and how RMAN works with

NetBackup.

How does RMAN work?The RMAN performs a wide variety of automated backup and recovery

functions. During a backup or a restore, RMAN provides the interface to the

databases, and it extracts and inserts data.

To start a database backup or restore, the database administrator runs a

command called rman. This command can be run from the command line, a

script, or an application such as NetBackup. The RMAN script is used as a

parameter to the rmancommand and specifies the operations to be performed(for example, backup or restore). The RMAN script also defines other


19/152

19Introduction


components of the operation, such as the database objects to be backed up or

restored.During a backup or restore, RMAN controls the data streams going into or out of

a database. RMAN can access storage devices when it is integrated with a media

management system, such as that provided by NetBackup.

How does NetBackup for Oracle work?

The following are prerequisites for performing backups to a storage unit:

Access to the NetBackup library

Generating unique file names

NetBackup for Oracle includes a library of functions that enable RMAN to use

NetBackup. This library is in install_path\NetBackup\bin.

When using the RMAN backupcommand, each resulting backup set contains at

least one backup piece (data file, data file copy, control file, or archive log) from

the target database. You must give each backup piece a unique name using the

formatoperand. Several substitution variables are available to aid ingenerating unique names. You can specify the format operand in the backup

command or in the allocatechannelcommand. NetBackup considers the

backup piece name as the file being backed up, so this name must be unique in

the catalog.

If an Oracle 8.0.x RMAN backup uses a file name that already exists in the

catalog, the original backup that has that name is deleted. In Oracle 8i or later,

the RMAN backup fails with a filealreadyexistsincatalogerror. For

information on generating unique file names, see your Oracle documentation.

Either NetBackup users or automatic schedules start database backups by

specifying a template or shell script in the file list of the Oracle policy. The

template or shell script specifies the backup commands that RMAN will perform

on the client.

For a backup:

1 Therman

command starts the requested operation on the databases.

2 When the process requires media to store backup data, RMAN starts a

user-directed backup by issuing a backup request.

3 The NetBackup media server connects to NetBackup for Oracle on the client

and transfers the database data to secondary storage.

A restore works in essentially the same manner except that RMAN issues a

restore request. This causes NetBackup to retrieve the data from secondary

storage and send it to NetBackup for Oracle on the client.RMAN supports parallel operations, so a single rmancommand can start more

than one backup or restore on the NetBackup system.


20/152

20 Introduction


The status for an RMAN operation is stored in the RMAN catalog or in the

database control file. This is the same status that is indicated by the output ofthe RMAN command used to run the backup or restore. This is the only status

that a database administrator must check to verify that a backup or restore has

been successful.

NetBackup also logs status, but only for its own part of the operation. The

database administrator cannot use the NetBackup status to determine whether

rmanwas successful. Errors can occur in rmanthat do not affect NetBackup and

are not recorded in its logs.

Incremental backups of Oracle databases

The RMAN provides true incremental backups. An incremental backup backs up

data files and includes only the blocks that have been changed since the last

incremental backup. For more information on the backup and recovery process,

see your Oracle documentation.

About the Oracle recovery catalogThe recovery catalog is a repository of information. RMAN uses the information

in the recovery catalog to determine how to perform requested backup and

restore actions. The recovery catalog contains information about the following

software components:

Data file and archive log backup sets and backup pieces.

Data file copies.

Archived redo logs and their copies.

Tablespaces and data files on the target database.

Stored scripts. These are named, user-created sequences of RMAN and SQL

commands.

Oracle recommends you use RMAN with a recovery catalog, especially if you

have 20 or more data files. However, you are not required to maintain a recovery

catalog with RMAN.

For information on the benefits and disadvantages of using a recovery catalog,

see your Oracle documentation.

NetBackup for Oracle XML export and XML importWhile Oracle RMAN performs backup, restore, and recovery of physical Oracle

database objects (data files, tablespaces, control files, and archived redo logs),

the NetBackup for Oracle XML export and XML import utilities provide backup

and restore of logical database objects (tables, users, and rows).

format ideal for database archiving.

NetBackup for Oracle users or automatic schedules start database XML export

archives by performing a manual backup of an Oracle policy, by invoking the

script or template at the command line on the client, or by invoking a template

through the Backup, Archive, and Restore interface.For an XML export archive:


22/152

22 Introduction


1 The NetBackup for Oracle script or template calls the bporaexputility with

a specified parameter file.2 The query processor uses the parameters in the specified file to build an SQL

query for each table.

3 Oracles OCI API executes the queries on the Oracle instance to be archived.

4 The query processor passes the output (including metadata and data for a

single table or multiple tables) to the XML Generator.

5 For each table passed, the XML generator builds one or more sets of XML

schema and XML instance documents.

6 XML data streams are backed up by NetBackup.

7 Alternately, bporaexp allows the files to be saved to an operating system

directory.

NetBackup for Oracle users start database XML import restores by invoking a

Restore interface.

For an XML import restore:

1 The NetBackup for Oracle script or template calls the bporaimputility with

a specified parameter file.

2 The input parameters that identify the XML archive to restore are passed to

NetBackup.

24 Introduction


3 NetBackup locates and reads the set of XML schema and instance

documents from the NetBackup storage unit.4 The XML data stream is passed to an XML parser, which passes the data to

the XML data loader.

5 The XML data loader uses Oracles OCI API to insert the data into the

database.

Optionally, bporaimp allows the XML data stream to bypass the XML parser

and be sent to an operating system directory. In addition, users can restore the

table metadata only into an operating system directory. bporaimpalso allowsimport from an operating system directory into Oracle.

Enabling NetBackup for OracleNetBackup for Oracle is installed automatically when you install the NetBackup

client. If you are planning your NetBackup for Oracle installation on a machine

that is not yet a NetBackup client, use the NetBackup for Windows install CD to

install NetBackup. A wizard guides you through the installation.

When the NetBackup client is installed, you must enable NetBackup for Oracle

by registering the license key on the NetBackup master server for that client.

Tocreateschedules

Schedules determine when NetBackup for Oracle initiates a backup. An Oraclebackup requires at least two different schedules:

An Application Backup schedule. When you create an Oracle policy,

NetBackup for Oracle automatically creates a Default-Application-Backup

schedule.

An Automatic Full Backup schedule. You create this schedule. It enables

scheduled backup operations on the client.

1 Double-click the policy name. The Policydialog appears.

2 Click the Schedulestab.

3 Double-click the schedule named Default-Application-Backup.

By default, the NetBackup sets the following:

The retention period is 1 month.

Multiplexing is 1.

The schedule is seven days per week and 24 hours per day. This ensures

that your backups can always commence.

Make any changes to the Default-Application-Backupschedule if needed.

4 Click OK.

5 Click Newto create another schedule.

6 Specify a unique name for the schedule.

7 Select Automatic Full Backup as the Type of Backup.8 Click the Start Windowtab.

9 Follow the instructions on the Startscreen to specify a time for this

schedule.

You must specify a time and a duration for the Automatic Full Backup

schedule. Depending on the size of the database and your site conditions, an

Automatic Full Backup can take a long time to complete. Choose a time

when your system is not likely to be in use. For example, you might specifySunday evenings from 1800-2300. By default, the retention period is

infinity, and the frequency is once per week.

10 Click OK.

11 Click Close.

NetBackup softwareVerify that the following requirements are met for the NetBackup server and

client software:

The NetBackup server software is installed and operational on the

NetBackup server.

The NetBackup server platform can be any that NetBackup supports. Forinstallation information, see the NetBackup Installation Guide.

The NetBackup client software is installed on the client that has the

databases you want to back up. This step also installs the database agent. (If

the database client is also a NetBackup server, the client software is installed

along with the server software.)

The install_path\NetBackupdirectory must exist on the client. For

installation information, see the NetBackup Installation Guide.

Make sure that you configure any backup media that the storage unit uses.

The amount of backup media that is required depends on the devices that

are used, the sizes of the databases that you want to back up, the amount of

data that you want to archive, the size of your backups, and the frequency of

backups or archives.

For information on using Media Manager, see the NetBackup

Administrators Guide, Volume I.

Database softwareVerify the following regarding the database software on the NetBackup client:

Oracle vendor software must be installed and operational.

One or more Oracle instances must exist.

For all Oracle 8 releases, make sure you have stopped Oracle services andshut down the Oracle database. For more information about when you need

to perform this step, see your Oracle documentation.

User interface terminology notesYou can perform many of the configuration steps in this chapter from the

NetBackup administration console on the master server. Depending on your

master servers platform, the console is available in one or two forms.

NetBackup supports a Java interface for both Windows and UNIX master

servers. In addition, NetBackup supports a Windows interface for Windows

master servers.

The Java and Windows interfaces are nearly identical. If interface differences

exist in the configuration procedures, this manual uses the following headings

Configuring the Maximum jobs per client


38/152

Configuring the Maximum jobs per clientThe following procedure shows how to set the Maximum jobs per client

attribute.

Toconfigurethemaximum jobs per client

1 In the left pane of the NetBackup administration console, expand Host

Properties.

2 Select Master Server.

3 In the right pane, double-click the server icon.

4 Click Global Attributes.

5 Change the Maximum jobs per client value to 99.

The Maximum jobs per clientspecifies the maximum number of concurrent

backups that are allowed per client. The default is 1. You can use the

following formula to calculate a smaller value:

Maximum jobs per client= number_of_streamsXnumber_of_policies

number_of_streams Thenumberofbackupstreamsbetweenthedatabase

For Oracle backups and restores, the number of jobs is difficult to determine.

This difficulty exists because Oracle internally determines when and how many

streams to run in parallel to optimize performance.

Tip:Enter a large enough value for the Maximum jobs per clientattribute to

meet the number of jobs that Oracle runs. You might need to experiment withdifferent values at your site.

Configuring a backup policy for a databaseA backup policy for a database defines the backup criteria for a specific group of

one or more clients. These criteria include:

Policy attributes

Backup schedules

Clients to be backed up

Backup templates or script files to be run on the clients

To back up a database environment, you need to define at least one Oracle policy

with the appropriate schedules. A configuration can have a single policy that

includes all clients, or there can be many policies, some of which include only

one client.

Most requirements for database policies are the same as for file system backups.In addition to the policy attributes for this database agent, other attributes are

available that you should consider.

For configuration instructions and information on all the attributes available,

see the NetBackup Administrators Guide, Volume I.

Adding a new policyThese instructions describe how to add a new backup policy for a database.

41/152

Set the window for the Application Backup schedule for 24 hours per day,

seven days per week. This window ensures that your operations are never

locked out due to the Application Backup schedule.

Configuring an Application Backup schedule

A database backup or XML export requires an Application Backup schedule. You

cannot perform backups if this type of schedule is not included in the policy. The

database agent automatically creates this schedule, named

Default-Application-Backup, when you configure a new database policy.

ToconfigureanApplicationBackupschedule

1 In the Policy dialog box, click the Schedulestab.

To access the Policy dialog box, double-click the policy name in the Policies

list in the NetBackup administration console.

2 Double-click the schedule that is named Default-Application-Backup.

3 Specify the other properties for the schedule.

See Schedule properties on page 45.

The backup window for an Application Backup schedule must encompass

the time period during which all scheduled jobs and unscheduled jobs can

occur. This window is necessary because the Application Backup schedule

starts the processes that are required for all database backups, including

those started automatically.

For example, assume the following:

Users perform database backup operations during business hours,

08:00 to 13:00.

The Automatic backups that use this policy start between 18:00 and

22:00.

In this scenario, the Application Backup schedule must have a start time of

0800 and a duration of 14 hours. Table 4-4on page 41 shows this example

schedule.

Using backup schedules, templates, and scripts

Later in this chapter you configure templates or scripts to use when you perform

backups and restores. Be aware that when an automatic schedule invokes a

script that a user authored, NetBackup does not provide safeguards to preventunusual behavior. For example, if an automatic backup schedule runs a restore

or recovery script.

To help guard against such mistakes, use a template instead of a script

whenever possible. When a template runs, it detects the backup type on the

schedule. You are responsible for specifying a template with the correct

operation type (backup or restore) in the policy.

Backup schedules and Snapshot Client features

The information in Types of backup schedules on page 43pertains to

stream-based backups. If you use the Snapshot Client option, be aware that

some of the information in that table may differ if you use certain Snapshot

Client features. For more information about backup schedules and Snapshot

Client features, see NetBackup for Oracle with Snapshot Client on page 105.

Oracle backup images and then synchronize the NetBackup and Oracle

repositories.

TomanageexpiredbackupimagesfromtheNetBackuprepository

In the Retention setting of the Application Backup Schedule, specify the

length of time before NetBackup expires a backup image. Note that the

retention setting has a slightly different meaning for an Application Backup

schedule versus an automatic backup schedule. For more information, see

Schedule properties on page 45.

TomanuallyremovereferencestobackupimagesfromtheOracleRMAN

repository

Use RMAN repository maintenance commands to remove references to

backup files. You can use these commands to delete backup image

information from both the Oracle RMAN repository and the NetBackup

repository. For more information on the RMAN repository maintenance

commands, refer to Maintaining the RMAN repository on page 66.

When a request is issued to delete a backup file from the RMAN repository,RMAN sends the request to NetBackup to delete the corresponding image

from the NetBackup repository, regardless of the retention level.

The client list enumerates the clients on which your NetBackup for Oracle

templates or shell scripts can run during an automatic backup. A NetBackup

client must be in at least one policy but can be in more than one.NetBackup attempts to run each template in the backup selections list for each

client in the client list. If a template is not valid on a particular client, for

example, if the Oracle home specified in the template does not exist on that

client, the template is skipped. A policy can contain multiple clients and

multiple templates. Only a subset of the templates needs to be valid on each

client. If the valid templates are successful, the entire backup is successful.

For a database policy, clients you want to add must have the following softwareinstalled:

Oracle

NetBackup client or server

The backup or XML export archive shell script(s) (unless, for Oracle, you are

using templates)

4 To add another client, repeat step 2and step 3.

5 If this client is the last client, click OK.

Adding backup selectionsThe backup selections list in a database policy has a different meaning than for

non-database policies. For example, in a Standard or Windows-NT policy, the

list contains files and directories to be backed up. In a database policy, you

specify templates or scripts to be run.

Rules for templates or scripts

Observe the following when using templates or scripts:

Make sure the scripts reside on each client in the client list. Scripts can

reside in any location. Make sure that NetBackup can access the location you

choose and that NetBackup can run the scripts.

Note that templates do not reside on the clients. Templates reside on the

NetBackup master server.

NetBackup installs sample scripts when you install the software, and you

can modify these scripts for your own use. Write the scripts to a location

49Configuration



49/152

outside of the original installation location. This way future NetBackup

installations do not overwrite your sites scripts.

If you use NetBackup for Oracle in a NetBackup server cluster, make sure

that the scripts reside in a location that is available after a failover.

Add templates or scripts to the backup selections list only if you want to set up a

policy for automatic backups. These templates or scripts are run for manual

backups and for Automatic Full Backup, Automatic Differential Incremental

Backup, or Automatic Cumulative Incremental Backup schedules as specified

under the Schedulestab. NetBackup runs the templates or scripts in the order

that the templates or scripts appear in the backup selections list.For more information on backup templates and scripts, seeCreating templates

and shell scripts on page 53.

Adding templates or scripts to the backup selections list

The following procedures describe how to add templates or scripts to the backup

selections list using the Java interface and using the Windows interface.

Caution:Be sure to specify the correct template and script names in the backup

selections list to prevent an error or possibly a wrong operation. Make sure that

the template or script resides on the client before you try to add it to the backup

selections list.

order of precedence for the runtime configuration variable settings.

Scheduled backups with templates:

1 Environment variables set by NetBackup.

For more information, see Environment variables set by NetBackup for

Oracle on page 53.

2 Environment variables set by the user.

For RMAN backups, these are set by the user with the Oracle RMAN

sendcommand and parmsoperand.For more information, see Oracle RMAN environment on page 51.

For XML export archives, environment variables are set by the user in

the XML export parameter file.

For more information, see Environment variables set by a user in the
