How to test RMAN backups

Hi,
We are running 24X7 systems and we take backup through RMAN.
I want to test my backups are working or not.
How can I do that.
Regards
MMU

restore validate database would be handy in your case.
When the above is issued, RMAN doesn't touch the live datafiles, it uses the previous valid backupsets to validate whether they are good enough for restore and recovery.
However, restoring on another host, will helpful to guage the restore and recovery timing.

How to identify rman backup level?

Hi,
I am using rman catalog for rman backup. how to identify rman backup level from catalog.
Thanks,

By doing the obvious and consulting the online documentation at http://tahiti.oracle.com
You will notice the list backup command output has a level column and this is also present in rc_backupset and/or rc_backuppiece.

Testing Rman Backup

Im testing my Rman backup.
We do our backup with the following command:
BACKUP AS COPY DATABASE TAG = 'Full Copy 2007/03/11 19:15:02';
On another machine, im testing the recovery like the following:
rman TARGET / NOCATALOG
startup nomount;
SET DBID my_bd_id;
RESTORE CONTROLFILE FROM '/mnt/jukprod_rman/rman_backup/20070311/c-3976015942-20070311-00';
alter database mount;
RESTORE DATABASE UNTIL TIME "TO_DATE('20070311 21:35:00','YYYYMMDD HH24:MI:SS')" PREVIEW;
Problem:
Rman wants 2 months of archive logs!!
no backup of log thread 1 seq 80017 lowscn 10641963078 found to restore
To
no backup of log thread 1 seq 85592 lowscn 13248466314 found to restore
That is 5575 archive logs that Rman needs. 100 Megs in size.
so Rman needs 557 gig of archive!
Whats wrong here?
How come Rman needs all those archive?
Why would rman need archive older that the backup since we did a backup as copy?
We want full backup with not need older archive logs.

Hi,
I don't think that BACKUP AS COPY is a real backup for future RESTORE command. May be you could use this statement for next commands:
BACKUP DATAFILECOPY
SWITCH DATAFILE TO
For good backup strategy you have to use statement like
BACKUP DATABASE INCREMENTAL LEVEL=0 PLUS ARCHIVELOG DELETE INPUT;
or simply
BACKUP DATABASE.
Than you have many old backups and you would like to restore in point of past
you have to use SET command.
If you use COPY of datafiles you have to do next:
restore spfile;
startup nomount
run{
set newname for_all_datafile_to_copy;
RESTORE CONTROLFILE FROM '/mnt/jukprod_rman/rman_backup/20070311/c-3976015942-20070311-00';
alter database mount;
switch all;
recover database;
open resetlogs;

How to distribute RMAN backup among tape volumes in OSB

Hi Guys,
I would like to ask some information about OSB. I have finally set up our Oracle Secure Backup 10.3.0.3.0 and initial OSB backup to tape is good using our test environment.
Now, our production servers has the following details:
Serv01
- Oracle Database 11.1.0.7
- Windows Server 2003 R2
- Current RMAN backup to disk full (level 0) is at 2TB.
Serv02
- this is our media server for OSB and we manage from here all other servers that we would like OSB to be implemented.
-Windows Server 2003 R2
- We have IBM tape library here with four drives
- Our tape volumes are 480GB each (compressed) we about 50 of them.
-Each tape volume has barcodes and our library has barcode reader
How can I group certain tapes (as a media family?) and use them for our level 0 backup. As you know, one tape cannot hold our level 0 backup so we need at least 5 tape volumes to hold our level 0 backup. Is there a step by step process of doing this? Or does anyone know how to do this?
Thanks and I would really appreciate your thoughts about this.

Yes, media families (like tape pools) are used to group backups on tape. Using a database backup storage selector, you set-up media policy so OSB will automatically select appropriate storage when for the backup per your settings. You may want to refer to this white paper which discusses media management:

How to verify RMAN backup ?

How to verify and validate the RMAN backups on daily basis?One more doubt at this point - if we can't locate any RMAN script in crontab(crontab -l) but still backup is occuring regularly, how can we see the script behind this?
Thanks in advance.

What you want see? If backup was executed without error or make sure that there is a valid backup on tape or disk.
So, If you want see if backup was executed successfull you must find the logs of backup or query "V$RMAN_OUTPUT" (check it on documentation).
If you want check if Database is Valid on Disk or TAPE as mentioned previously "RESTORE VALIDATE DATABASE" (check it on documentation).
Where we can locate RMAN SCRIPT? It's hard to answer.
It' your env, you should find out. The options are: Crontab / Oracle Enteprise Manager / Third-Party Backup Software / Job Scheduler.
Also you can try : Take a time of backup was executed and check on shell a time of exection of backup " ps -ef |grep rman" you will find from where script was started.

How to test the backup is happend correctly

Hi Experts
We are running CRM 5.0 ,mssql2005 on windows 2003.Landscape of DEV and PRD. Daily we are tacking the backups to External disks.
How we can check that backups were happening properly though its showing successsful message it should not become a problem while restoring.
We dont have the test server to test the restoration is happening correctly or not.
So experts please suggest
Note : Helpful answer is rewarded
Regards
kumar

Hello,
there is no other way of testing the backup as than restoring the backup. You can restore the backup to any available machine (workstation etc.) with a SQL Server (of the same version) installed. Run a dbcc checkdb once the restore is done to ensure physical consistency of the database.

How to schedule RMAN backup

Hi experts,
I need to schedule automated RMAN backups in 10G(RMAN database) and i need to include the support for Oracle 8i, 9i and 10g database backups.
Any type of suggestions are welcome.
Thanx in Advance,
Senthil

Hi,
Where do you want to backup to? Do you want to backup to disk or to tape drive? Many of the tape drive softwares does have the capability of scheduling the jobs. If you want to backup to disk, then you can use your OS scheduling features.
Before all of that, you will need to write and test indivudual scripts to backup and restore.

How to check RMAN backup report or log

Hi Guys,
I have RMAN schduled to backup my database daily.
Please what are the steps to check the report of the backup to see what was actually backed up and if it backup up ok
Thanks

Use "LIST BACKUP" to display information about backup sets, proxy copies, and image copies. With LIST command you can list the following:
- Backups and copies that do not have the status AVAILABLE in the RMAN repository
- Backups and copies of datafiles that are available and can possibly be used in a restore operation
- Specified archived logs, backup sets, backup pieces, control file copies, datafile copies, and proxy copies
- Backups and copies restricted by tag, completion time, recoverability, or device
- Incarnations of a specified database or of all databases known to the repository
- Stored scripts in the recovery catalog
Examples on how to use LIST command are listed below:
RMAN> LIST BACKUP;
RMAN> LIST EXPIRED BACKUP;
RMAN> LIST BACKUP OF DATABASE;
RMAN> LIST BACKUP SUMMARY;
RMAN> LIST BACKUP BY FILE;
RMAN> LIST ARCHIVELOG ALL;
RMAN> LIST COPY OF DATABASE ARCHIVELOG ALL;
RMAN> LIST COPY OF DATAFILE 1, 2, 3;
RMAN> LIST BACKUP OF ARCHIVELOG FROM SEQUENCE 1437;
RMAN> LIST BACKUPSET OF DATAFILE 1;You can use the VALIDATE keyword of the BACKUP command to do the following:
- Check datafiles for physical and logical corruption
- Confirm that all database files exist and are in the correct locations
For example, you can validate that all database files and archived redo logs can be backed up by running a command as follows:
RMAN> BACKUP VALIDATE DATABASE ARCHIVELOG ALL;I suggest you read Oracle® Database Backup and Recovery Manuals:

How to test T61 backup battery?

Hello,
am taking apart a T61 for cleaning, OS reload etc and am thinking of testing the backup battery while I am in the maintenance mode. The maintenance manual indicates to remove the battery and measure the voltage, but doesn't indicate how to do this, I have a multimeter but have no idea how to test this particular part.
Any suggestions welcome.
Thanks!

Solved!
Go to Solution.

it's a simple DC battery with two wires, you just check the voltage across them, but I'd recommend you remove any bios passwords you may have set first.
Also, these batteries don't often go bad, so you can simply remove the main battery and unplug the AC for a few hours and if the clock remains set, the cmos battery is working.

How to move rman backups on tap from disk

Hi,
I have rman backup files on the disk, now how we can move these files to tap. is there any rman command or is there any script to move.
Thank you!

Do you use FRA (Flash recovery area)?
If you use FRA then configure RMAN to take backup to tape. And backup fra to tape.
RUN
ALLOCATE CHANNEL ch0 TYPE ‘SBT_TAPE’;
BACKUP RECOVERY AREA;
RELEASE CHANNEL ch0;
If you don't use FRA then you can backup your backupsets which are on the disk to tape.
RMAN> BACKUP DEVICE TYPE SBT BACKUPSET ALL;

How to control RMAN backup of archive logs in FRA

Setup:
11.2.0.2 GI
ASM Diskgroup for Fast Recovery Area
10.2.0.4 Enterprise Database
Without Catalog Database
To get familiar with Flashback Database we set up RMAN Backups
without deleting the archive logs,
as published in Oracle10g / 11g - Getting Started with Recovery Manager (RMAN) (Doc ID 360416.1)
"These deletions are managed by Oracle when space is required."
We observed that RMAN takes backups of all archive logs every time,
here we go with backing up archive logs every 30 minutes.
So the question is:
Is this (backing up all archive logs every time) the expected behavior or
the result of not using a catalog database or
any other mismatch?
thanx for any hint
Michael

Hi Michael,
In Note 360416.1 it refers to two archivelog backup commands.
BACKUP ARCHIVELOG ALL;and
BACKUP ARCHIVELOG FROM TIME 'SYSDATE-30' UNTIL TIME 'SYSDATE-7';Your question:
Is this (backing up all archive logs every time) the expected behavior or the result of not using a catalog database or any other mismatch?If you used the first script you will backup alle archivelogs everytime.
If you use the second one it will do a subset (probably not the range you want to backup...)
You could implement another script
BACKUP ARCHIVELOG NOT BACKED UP 2 TIMES;So every archivelog is only backed up twice.
Check
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta009.htm#i78895
for more information.

How to take RMAN backup through a single (default) channel

Sir,
In an interview I was asked a question that how can I allocate a single channel to multiple databases to take simultaneous backup. I was unanswer.
Pl. tell me if it is possible what will be the query with an example.
Regards
Neeraj

No it's not at all possible to take backup of multiple database through the manually allocated channel.
Allocating the channel manually is only possible while running the commands in batch mode
eg. run {
allocate channel ch1 type disk format='/backup1/RMANBACKUP/PROD521_%s_%p';
allocate channel ch2 type disk format='/backup1/RMANBACKUP/PROD521_%s_%p';
backup database setsize=12582912;
release channel ch1;
release channel ch2;
And you can connect through single rman prompt to only one target database not more than that. So at any point of time you connect to only one database you can user channels to backup that database only.
connected to recovery catalog database
RMAN> CONN TARGET SYS/ORACLE@RMAN
RMAN> CONNECT TARGET SYS/ORACLE@RMAN
connected to target database: RMAN (DBID=1528877161)
RMAN> CONNECT TARGET SYS/ORACLE@CLS
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-06167: already connected
