Validate rman backups

Hi,
oracle 9.2.0.1
rman Incremental cumalative backups
HI,
i do incremental cumalative backups. Full Level 0 on friday, level 1 incremental done Mon - Thurs.
i noticed that if i run a RESTORE DATABASE VALIDATE command, it checks/uses all the pieces that are part of the FULL LEVEL 0 only. But this does not tell me if the incremental backup pieces created are good or not.
How (without actually restoring to test server) can i test/validate up-to the latest incremental daily backup?
J

RESTORE VALIDATE will only do full backups, LEVEL 0 backups, controlfiles, spfile, datafile copies and archivelogs. However, you can VALIDATE a LEVEL 1 backupset with simply:
RMAN> VALIDATE BACKUPSET <backupset_#>;

Validate RMAN backup

Hi All,
I have database of 3.5 TB. Backup strategy is RMAN hot backup. I need your suggestions " How could I verify/validate RMAN backup ". We don't have that much disk available to abstract RMAN backup and validate database.

Please read the RMAN documentation under 'restore database validate'
Please do not conform to the standards of all other posters from Hyderabad in this forum to never read any manual prior to posting.

RMAN Backup Validate

Hi,
We are having prod rman backup but not sure if it is valid one or not.
Can any one suggest me how to valdate if those backup pieces can be used to restore the db for cloning of dev instance.

siva

Hello,
You can use cross check backup.
Please view this Link:
http://ss64.com/ora/rman_crosscheck.html
Two wrong things,
1) Crosscheck is not the command to validate the restore but to check the physical existence of the backup pieces in comparison to the control file's repository. The op said,"We are having prod rman backup but not sure if it is valid one or not." So the restore validate is the command that's needed here based on what OP has said.
2) Please use official oracle documentation for the reference as the error correction is guaranteed over there compared to the external sites like the one you have linked which almost never update/correct their content.

9i Database - Restore to a new host, validating RMAN backup

Hi all,
I could use your help, for any of you who remember how to do this in 9i. On one of my production databases, running 9.2.0.6.0, I have a nightly RMAN script that writes the backup to a large shared drive (this is on a Windows 2003 server). This backup uses a recovery catalog.
I have a test server, and I want to try and restore last night's backup on this test server, without touching the recovery catalog - purely as a means to go through the recovery process, and to validate our backups (this is also for SOX compliance, as this database is for the financial system).
I have been looking through the 9i documentation, and was hoping to have some detailed steps here: http://download.oracle.com/docs/cd/B10501_01/server.920/a96566/rcmrecov.htm#1007514
but I don't see a lot of information there.
I believe that this should be a rather simple process. On the test server, I have installed the 9.2.0.6 software, and created the Oracle Service using the same name as production. The test server can also see the shared drive that houses the backup files from the production system.
Here are the steps I am trying, please let me know what I need to change. Thanks all!!

RMAN-06172: no autobackup found or specified handle is not a valid copy or piece

Many thanks for the helpful replies so far, Hemant!! I had to shelve this issue for a few days, back at it today.
I have made some progress, I am able to restore the control file now - what I am doing, is copying the autobackup controlfile from the network drive over onto the server locally (E:\oracle\ora92\database\BACKUPCONTROL.ORA), then I am able to restore the controlfile with this:
restore controlfile from 'E:\oracle\ora92\database\BACKUPCONTROL.ORA';
And I can see that it restores all 3 of my controlfiles.
The next step would be to do the database restore. When I issue the "restore database;" command, I can see that it lists out all of the datafiles that it needs to restore from the backup set, but then after about a minute, I see these error messages pop up:
RMAN-00571: ===========================================================

ORA-27067: skgfdisp: size of buffer is invalid
OSD-04026: Invalid parameter passed.
When I looked up those last 2 error codes on Metalink, I see document ID 213858.1 that looks like this normally happens when the backup piece that has Read-Only permissions. I have confirmed that the backup files on the network drive are not Read-Only, I have full Read/Write privileges on them. So once again, I am stumped.
Any thoughts? I might go ahead and log an SR for this, to try and get it resolved.
Thanks!

Whats the difference ( RMAN BACKUP)

Please let me know the diffrence between
1.Alter database begin backup
2. backup database
After my own research all i can find is that Alter database begin backup freeeze the SCN and then we can copy the files from OS level
Where backup database directly create backup set ( backup piece) ..
I would like to know the functional differnce between the two if there is any...
Plus ...doing alter database begin backup ...am i not taking care of logical corruption..
Does alter database being backup does not validate or find out the logical corruption before...
I also came know from a OCA that it just puts in backup mode and dont really pay attention to checking or validating the files...before backin up.
Is that true?
Thanks in advance
Max

I would the functional differnce between the two if there is any...The backup database doesn't need to freeze any headers as RMAN knows how to read the datafiles of oracle. Its knows them very well. So there is nothing we need in the case of rman to check that when the backup was done.

Yes its correct, the commands, alter database begin backup pr backup database doesn't check for any sort of corruptions. Fordoing that, you either need to fire up oS util. DBV for checking the physical corruptions or use RMANs Backup Validate or Backup Validate Check Logical to check for physical/logical corruptions.

Then dropped the table, and tried to take backup of the database and it is failing again with the same error..
ANY SOLUTION TO TAKE BACKUP OF THE DATABASE.
anyhow we can SET MAXCORRUPT FOR DATAFILE 3 to value, but does this works all time...

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 ensure the rman backup is successful?

Hi,
we have scheduled rman backup jobs.
1. But how do we ensure all the rman backups are successful?
2. if the rman writes directly to tape, how do we ensure all tape backups are successful?
thanks
andrew

But what is incremental merge, couldn't find in the 10g manual?check it out on http://download.oracle.com/docs/cd/B28359_01/backup.111/b28270/rcmquick.htm#BRADV89354
do you use image backup in real production environment?Of course. We have a standard to to use image copies that way.
what do you suggest to do with rman normal way of backup or go for image backup?Depends on your specific situation. Like anything else, I prefer to provide some rationale on the recommendation.
Image Copies with Incremental Merge
Pros:
(1) one one full backup taken ever; no need to take another full backup
(2) the restore time is the same, regardless of the day of the week the db failed
(3) every day the incremental merge's success means the backup was good - an automatic validation
(4) it allows you to quickly switch to copy, rather than restore
Cons:
(1) Space requirement is more (since it's a bit to bit copy)
(2) can't do a point in time recovery from the disk alone
(3) can't go to the tape directly; must be a disk based backup.
Backupsets with Incremental Backup
Pros:
(1) space requirement is lower (since only never-used blocks are not copied)
(2) point in time recovery is possible
(3) direct backup to tape possible (no need for disk backup)
Cons:
(1) restore time varies depending on the day of the week the db failed
(2) you have to take a full backup regularly, perhaps once a week
(3) no validation unless you use validate backupset (takes resources)
So, as you can see, there are pros and cons to each approach. You have to decide for yourself which one weighs more (or less) to come to a conclusion.
Hope this helps.

RMan Backup - Dedup ratio

Hello
We make every night a rman backup. This backup will be safed on the netbackup system. but we have the problem that our deduplication ratio is very bad. is there any commands in rman, that the dedup ratio will be better?
Thanks...
Best regards...

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:

Rman Backup time error

Today i saw this error in our production backup time .
Please let me know how to leave out from this.

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

Regs,
Brij

Also, be aware that rman: backup validate (check logical) command could not show the corrupted blocks if that block are newer used(or used before, but freed later for example). In this case, rman validate does not populate V$database_block_corruption but it also does not allows you to continue with your backup.
So the solution will be, as previous posters said, either set the limit for the sustained number of corrupted blocks or format/repair the corrupted block.
For checking the corrupted blocks you could also use db verify utility(dbv). This will definitely show you the details about corrupted blocks, even they are not used ever.

RMAN backup piece corruption.

Hi,
I m having multiple databases where RMAN backup configured and scheduled. I want to know from backup piece how I can know the block corruption?

What is the version of your RMAN utility.
Try this:
Start RMAN and connect to a target database and recovery catalog (if used).
Run the BACKUP VALIDATE command.
For example, you can validate that all database files and archived logs can be backed up by running a command as shown in the following example. This command checks for physical corruptions only.
BACKUP VALIDATE
DATABASE
ARCHIVELOG ALL;
To check for logical corruptions in addition to physical corruptions, run the following variation of the preceding command:
BACKUP VALIDATE
CHECK LOGICAL
DATABASE
ARCHIVELOG ALL;
In the preceding examples, the RMAN client displays the same output that it would if it were really backing up the files. If RMAN cannot back up one or more of the files, then it issues an error message. For example, RMAN may show output similar to the following:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

Solution : As in above case, I have started the database in mount and then alter it to the open mode but it doesnot work out. After some analysis ,troubleshooting and googling, we have decided to flush the shared pool component of the SGA . So, we have started the database in mount stage and then flush the shared pool and further alter it to open stage . Below are the steps performed to solve this issue .
SQL> shut immediate
ORA-01507: database not mounted
