Practice: RMAN Backup Command

This practice covers the BACKUP command in RMAN used to make backup sets of datafiles, tablespaces and the whole database.

 Assumptions

 ·        This practice assumes that you have a target database available.  A recovery catalog is not required.  

Instructions

 1.      Connect to the target database using RMAN and if necessary start the target database. 

RMAN> connect target sys/change_on_install 

connected to target database: ORCL (DBID=981440495) 

RMAN>

2.      Use the SHOW ALL command to show the stored configuration for RMAN.

RMAN> show all;

 

using target database controlfile instead of recovery catalog

RMAN configuration parameters are:

CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default

CONFIGURE BACKUP OPTIMIZATION OFF; # default

CONFIGURE DEFAULT DEVICE TYPE TO DISK;

CONFIGURE CONTROLFILE AUTOBACKUP OFF; # default

CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default

CONFIGURE DEVICE TYPE DISK PARALLELISM 3;

CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default

CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default

CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   'D:\backup\%U' MAXPIECESIZE 50 M;

CONFIGURE MAXSETSIZE TO UNLIMITED; # default

CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'D:\ORACLE\901\DATABASE\SNCFORCL.ORA'; #

default

 

RMAN>

3.      If the stored configuration is correct, the only necessary step is the command to back up your database.

RMAN> backup database;

 

Starting backup at 08-MAR-02

allocated channel: ORA_DISK_1

channel ORA_DISK_1: sid=12 devtype=DISK

allocated channel: ORA_DISK_2

channel ORA_DISK_2: sid=13 devtype=DISK

allocated channel: ORA_DISK_3

channel ORA_DISK_3: sid=14 devtype=DISK

channel ORA_DISK_1: starting full datafile backupset

channel ORA_DISK_1: specifying datafile(s) in backupset

input datafile fno=00005 name=D:\ORACLE\ORADATA\ORCL\EXAMPLE01.DBF

input datafile fno=00006 name=D:\ORACLE\ORADATA\ORCL\INDX01.DBF

input datafile fno=00008 name=D:\ORACLE\ORADATA\ORCL\USERS01.DBF

 

4. Verify the backup files using Operating System commands. If you do not specify a format, RMAN uses %U by default, which guarantees a unique identifier. %U specifies a convenient shorthand for %u_%p_%c that guarantees uniqueness in generated backup filenames. %u specifies an 8-character name constituted by compressed representations of the backup set number and the time the backup set was created. %p specifies the piece number within the backup set. %c specifies the copy number of the backup piece within a set of duplexed backup pieces.

Practice: Automatic Backup of the Controlfile

This practice covers the configuration of automatic controlfile backup. This configuration is stored in the controlfile and every time any backup or copy command is issued, the controlfile is also backed up or copied.

Assumptions

·        The target database needs to be mounted or open. A recovery catalog is not required.  

Instructions

1.      Start RMAN and connect to your target database. Using the SHOW command find the stored setting for the controlfile autobackup. 

C:\WINNT>rman target sys/oracle@orcl

Recovery Manager: Release 9.0.1.1.1 – Production

© Copyright 2001 Oracle Corporation. All rights reserved.

Connected to target database: ORCL (DBID=981440495)

RMAN> show controlfile autobackup;

RMAN configuration parameters are:

CONFIGURE CONTROFILE AUTOBACKUP OFF;

RMAN>

2.      Use the configure command to automatically back up the controlfile after any backup or copy command. Confirm the configuration.

RMAN> configure controlfile autobackup on;

New RMAN configuration parameters:

CONFIGURE CONTROLFILE AUTOBACKUP ON;

New RMAN configuration parameters are successfully stored

RMAN> show controlfile autobackup;

RMAN configuration parameters are:

CONFIGURE CONTROLFILE AUTOBACKUP ON;

RMAN>

This completes this practice

 

Practice: Backup the Control Files.

In this practice you will backup the controlfiles.

Assumptions

·        The target database needs to be mounted or open.  A recovery catalog is not required.  

Instructions

1.      Issue the backup command to backup all archivelog files and then delete the input files. 

RMAN> BACKUP ARCHIVELOG ALL DELETE ALL INPUT;

Starting backup at 14-MAR-02

current log archived

using channel ORA_DISK_1

using channel ORA_DISK_2

using channel ORA_DISK_3

channel ORA_DISK_1: starting archive log backupset

This completes this practice.

 

Practice: Using the RMAN copy command

This practice uses the copy command in RMAN to make image copies of files instead of backup sets.

Assumptions

·        The target database needs to be mounted or open.  A recovery catalog is not required.   

Instructions

1.      Issue a Report command to find all of the data files in the database.

RMAN> report schema;

Report of database schema

File K-bytes Tablespace  Datafile Name

2     204800 UNDOTBS     D:\...\ORCL\UNDOTBS01.DBF

8      25600 USERS       D:\...\ORCL\USERS01.DBF

RMAN> >

2.      Issue the RMAN copy command to backup a single data file. If controlfile autobackup is on, the control file will be backed up as well.

RMAN> COPY DATAFILE "D:\ORACLE\ORADATA\ORCL\SYSTEM01.DBF" TO

2> "D:\backup\system01.bak";

Starting copy at 14-MAR-02

using channel ORA_DISK_1

using channel ORA_DISK_2

using channel ORA_DISK_3

channel ORA_DISK_1: copied datafile 1

output filename=D:\BACKUP\SYSTEM01.BAK recid=2 stamp=456527729

Finished copy at 14-MAR-02

Starting Control File Autobackup at 14-MAR-02

piece handle=D:\BACKUP\C-981440495-20020314-02 comment=NONE

Finished Control File Autobackup at 14-MAR-02

RMAN>

3.      Issue the RMAN copy command to backup a single archivelog file.

COPY archivelog

2> "D:\oracle\oradata\orcl\arc1\arc00048.001" to

3> "D:\backup\arc00048.001";

Starting copy at 14-MAR-02

using channel ORA_DISK_1

using channel ORA_DISK_2

using channel ORA_DISK_3

channel ORA_DISK_1: copied archive log

input archive log thread=1 sequence=48 recid=68 stamp=456519020

output filename=D:\BACKUP\ARC00048.001 recid=70 stamp=456527972

Finished copy at 14-MAR-02

Starting Control File Autobackup at 14-MAR-02

piece handle=D:\BACKUP\C-981440495-20020314-03 comment=NONE

Finished Control File Autobackup at 14-MAR-02

RMAN>

This completes this practice.
