Full DB backup using RMAN

Hi
I have RMAN backup taken using "backup database" command. Does this backup include control files, spfile, redo logs, archive logs along with datafiles?
How should be a backup strategy in order that db is recovered without any dataloss?
Thanks
JIL

If you CONFIGURE CONTROLFILE AUTOBACKUP ON controlfile and spfile backups are automated. They go to the FRA (FlashRecoveryArea) if you have an FRA defined, else they go to $ORACLE_HOME/dbs (on Unix/Linux).
Redo Logs are never backed up by RMAN.
BACKUP DATABASE does not include ArchiveLogs unless you run BACKUP DATABASE PLUS ARCHIVELOG. Alternatively, run BACKUP ARCHIVELOG ..specification.. seperately after the BACKUP DATABASE.
Please read the Oracle documentation on Backup and Recovery.

Full Hot Backup using RMAN?

Dear all,
I want to take a full hot backup every week on sunday and the followings are the commands.
run
allocate channel ch1 type disk format '/db/BACKUP/RMAN/backup_%d_%t_%s_%p_%U.bck';
backup
incremental level 0
database
plus archivelog delete input;
backup current controlfile;
backup spfile;
release channel ch1;
I have the following questions:
1) Am I need to define a directory named as "'/db/BACKUP/RMAN/backup_%d_%t_%s_%p_%U.bck", so that the backup copies will put it here,right?
2) What format needs to be save in where and how to run it on weekly schedule basis?
3) I saw above script with "channel ch1", can I change it to "channel ch2"?
I am a beginner using RMAN, please let me know.
Best Regards,
amy

Which database version on which OS (looks like Unix/Linux)?
You have to create the directory '/db/BACKUP/RMAN', 'backup_%d...' is the filename created by RMAN.
%d Specifies the name of the database;
%t Specifies the backup set time stamp, which is a 4-byte value derived as the number of seconds elapsed since a fixed reference time. The combination of %s and %t can be used to form a unique name for the backup set;
%s Specifies the backup set number. This number is a counter in the control file that is incremented for each backup set. The counter value starts at 1 and is unique for the lifetime of the control file. If you restore a backup control file, then duplicate values can result. Also, CREATE CONTROLFILE initializes the counter back to 1;
%p Specifies the piece number within the backup set. This value starts at 1 for each backup set and is incremented by 1 as each backup piece is created;
%U Specifies a system-generated unique filename (default).
For scheduling a cron job could be defined or you use Enterprise Manager (10g and higher)
Channel name doesn't matter.

Error in Database backup using RMAN.

Hi
While taking full online backup using RMAN i got the following error.
ORA-19566: exceeded limit of 0 corrupt blocks for file /oracle/DEV/sapdata2/dev640_6/dev640.data6
Please help me how to resolve this issue.

Hi,
Please perform DBverify Job and Also analyze the alert<SID>.log file for your Database to get more information about such logical or physical corruption. You may require Block level recovery for the complained DB Files. Please refer this useful document " [Early Detection and Correction of Data Block Corruptions Using RMAN |http://www.ioug.org/client_files/members/select_pdf/04q4/RMAN.pdf]" and share the same with your Oracle DBA.
You can execute the following commands to get information about corrupted block(s), if its there.
select * from v$backup_corruption;
select * from v$database_block_corruption;

Am I Correct if not please any one answer me why the online redologs are not copied.No. They are not needed because the only valid backup for a cold (or noarchivelog mode database) backup is a consistent backup. Since the backup is already consistent there are no changes to apply.
The online redo logs are (re)created/reset by the "resetlogs" clause when the database is opened.

Cold backup using RMAN

Dear All,
db_version :10.2.0.4
os_version:Window 2003 server
Environment:Test
I wish to perform cold backup using RMAN for the same i want to know following :
1. What is the script / command ?
2. How to restore cold backup completely ( ex:- if i lost all my data,redo and archives )
3. Is it mandatory to open the database in RESETLOG mode after recovery ( since i have a cold backup ) ?
Thanks in advance

A "Cold" Backup is called a "Consistent" Backup.
See http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup003.htm#sthref297
Backup :
From the RMAN command line :
SHUTDOWN IMMEDIATE
STARTUP MOUNT
BACKUP DATABASE
BACKUP CURRENT CONTROLFILE -- to get the controlfile in a separate backupsetRestore :
STARTUP MOUNT
RESTORE DATABASE
ALTER DATABASE OPENIf you use an SPFILE, you can have an SPFILE backup included automatically with the controlfile backupset with CONFIGURE CONTROLFILE AUTOBACKUP ON and CONFIGURE CONTROLFILE AUTOBACKUP FORMAT ...

Backup using RMAN

Hi,
I want to perform the first backup with RMAN and I used this command and I got error:
RMAN> BACKUP AS COPY DATABASE;
can not backup or copy active file in noarchivelog mode.
But in order to turn on the log_mode to ARCHIVELOG, first I need to do shutdown the db and perform the backup. Right?
So how can I get my first backup using RMAN if the log mode is in NOARCHIVELOG mode?
I also performed controlfile autobackup on but I'm not sure the controlfiles are being backed up. How can I verify this and where I can find the controlfile backup file?
Thanks,

Hi
Yes, you must shutdown the database and set it to start in ARCHIVELOG mode.
After that you can connect to the rman catalog and the target database and execute a backup.
eg. RMAN> backup database;
You can search other example posted by me:
eg.
- Re: Backup with RMAN
- Re: How do i set up this backup strategy?
To be sure that you backed up your control file you can issue the rman-command:
RMAN> list backup of controlfile summary;

PERFORMING A TEST BACKUP (VALIDATE BACKUP) USING RMAN

제품 : RMAN
작성날짜 : 2002-05-30
PERFORMING A TEST BACKUP (VALIDATE BACKUP) USING RMAN
=====================================================
PURPOSE
RMAN을 이용하여 Test Backup을 수행하기 위한 정보를 제공한다.
EXPLANATION
8.1.7 부터 RMAN에서 BACKUP command에 VALIDATE keyword를 사용할 수 있게 되었다
이 명령의 수행은 다음과 같은 작업을 수행한다.
- Datafile의 physical and logical corruption을 check한다.
- 모든 database file들이 존재하는지, 그리고 올바른 위치에 있는지를 검증한다.
RMAN은 실제적으로 backupset을 생성하지 않는다 그러나 그것들이 backup될 수
있는지 없는지를 결정하기 위해서 기술된 file들을 scan한다.
BACKUP VALIDATE 는 backup job을 수행시 수행되는 것을 제외하고는
RESTORE VALIDATE와 거의 비슷하다.
EXAMPLE
아래와 같은 command들을 수행하여 backup하고자 하는 database file과 archived redo
log들이 실제로 backup될 수 있는지를 검증할 수 있다.
RUN {
ALLOCATE CHANNEL ch1 TYPE 'sbt_tape';
BACKUP VALIDATE
DATABASE
ARCHIVELOG ALL;
Note: MAXCORRUPT or PROXY parameter는 VALIDATE option과 함께 사용할 수 없다.

Full db backup using expdp

Hi All,
My database version is 10.2.0.2 & I want to take full database backup using expdp.
This is the parfile I use.
userid=system/manager
full=y
directory=exp_dmp
parallel=4
The database size is 45 gb & the expdp dumpfile size comes to around 31gb. What can be done to compress the expdp dumpfile?
or is there some other parameters which i need to use?
thanks

I agree expdp is logical backup.
In 10g compression=metadata_only is the only option that can be used, so that does not help to compress the backup.
due to size restrictions, i want the dumpfile to be compressed as and when the backup is running, how to achieve this?

Time for BACKUP using RMAN

Does anyone know the approximate time required for backing up 10GB datbase using RMAN?

Hi ...
Also the speed depend on the way you use to do the backup ...
Using parallel option of RMAN ( setting an appropiate set of channels ), and using a set of drives that allows multiplex write on tape ( ie, STK9840 w/Veritas Netbackup) a 10 Gb database full online backup will take not more than 5.6 minutes (using 2 drives )
Using 4 drives your backup can be reduced to 3 minutes ..

Script for cold backup using RMAN

Dear all,
db_version:-10.2.0.4
os_version:- Windows 2003 server
I wish to schedule a script that will take cold backup of my database using RMAN.
Any help is appreciated ..
Edited by: user12000301 on May 18, 2011 5:02 AM

Dear All,
Thanks a lot for your valuable time :
However i have managed to do it as follows :
1. First i have configure the parameter of RMAN ( Since it is my UAT in Noarchive log mode), I have never tried RMAN cold backup on the same.
Following is the out put of SHOW ALL;
RMAN> show all;
using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 2 DAYS;
CONFIGURE BACKUP OPTIMIZATION OFF;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'D:\DB\RMAN_BKP\BACKUPS%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO COMPRESSED BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'D:\DB\RMAN_BKP\BACKUPS\DB_%U.%r';
CONFIGURE MAXSETSIZE TO UNLIMITED;
CONFIGURE ENCRYPTION FOR DATABASE OFF;
CONFIGURE ENCRYPTION ALGORITHM 'AES128';
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'D:\DB\RMAN_BKP\BACKUPS\SNCFDB.ORA';
2. I have created a rman_cold_bkp.bat file which has following entry :
cd c:\oracle10g\bin
set oracle_sid=DB
rman target system/*** @D:\DB\RMAN_BKP\SCRIPT\rman_cold_bkp.rcv log=D:\DB\RMAN_BKP\SCRIPT\rman_cold_bkp.log
exit
3. Whereas rman_cold_bkp.rcv file contains following contents:
run
allocate channel C1 device type disk;
shutdown immediate;
startup mount;
backup database;
alter database open;
release channel C1;
exit
I did checked it and it;s working fine for me :-)

Girish

Doubt in taking backup using RMAN CATALOG

Hi,
when i was using RMAN CATALOG.
can i create separate database for catalog on server machin/backup server?
if create separate database for catalog?
how to create a separate database for catalog and plz give clear instruction one by one.
thanks

can i create separate database for catalog on server machin/backup server?
Yes.
and
also you create separate user to "recovery catalog" and "separate tablespace" for recovery catalog.
1.creation of recovery database catalog some like normal database catalog.
but after creation of database you create one user for recovery catalog.
Note :
"User that owns the recovery catalog schema. This is a user defined in the recovery catalog database that has been granted the RECOVERY_CATALOG_OWNER role."
