When I go to /tmp & ls –ltr
I do not see the files ??? does restore validate in this case only check whether RMAN can restore the files or should it also restore the files to /tmp.

That's correct. RESTORE..VALIDATE will only scan the file and ensure it actually exists and is not corrupt.
In fact, for 10g you don't even need to specify a location:

Restore validate database

Hi,
1) I've 2 databases, which are scheduled for weekly full online backup(from scheduler/rman) on fri. and sat. respectively, and there is daily incrementally updated backup, plus the archivelogs on both the database.
When I do restore validate database, in one database validate restores the last full online backup, whereas in the other it scans the datafile copies.
I'm just curious as to what algorithm rman follows to validate the database restore?
2) Is there some way to automate this VALIDATE in a script, I'm finding it real pain to first LIST BACKUP SUMMARY, identify BACKUPSET keys, then manually key in to
- VALIDATE BACKUPSET XXXX,XXXX,XXXX
- RESTORE VALIDATE CONTROLFILE
- RESTORE VALIDATE SPFILE
- RESTORE VALIDATE ARCHIVELOG FROM TIME 'XX-XXX-XX'
- RESTORE VALIDATE DATABASE

>>

What do you mean by datafile copies? Are you talking about RMAN image copies?
RESTORE... VALIDATE causes RMAN to select existing backups that it would use to perform a RESTORE operation, and scan them all to ensure that they are present and free of corruption.
RESTORE... PREVIEW identifies the backups which RMAN will use to perform any RESTORE operation. Output from a RESTORE... PREVIEW is in the same format as the output of the LIST command.
Oracle prefers image copies over backupsets, if exists, for restore and recovery.

Restore Validate Database vs Backup Validate Database

Hi,
I want to add the following sentence after taking the backup using following command (backup as compressed backupset database plus archivelog;)
restore database validate;
or
backup validate database;
which one is best?

It depends on what you are trying to accomplish, as per documentation:
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta009.htm#sthref141BACKUP .. VALIDATE: Causes RMAN to scan the specified files and verify their contents, testing whether this file can be backed up. RMAN creates no output files. Use this command periodically to check for physical and logical errors in database files.
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta051.htm#sthref796
RESTORE... VALIDATE causes RMAN to select existing backups that it would use to perform a RESTORE operation, and scan them all to ensure that they are present and free of corruption.>
Guessing what you're trying to do, I recommend:
backup check logical as compressed backupset database plus archivelog;
restore validate database;
CHECK LOGICAL. Tests data and index blocks that pass physical corruption checks for logical corruption, for example, corruption of a row piece or index entry. If RMAN finds logical corruption, then it logs the block in the alert.log and server session trace file. HTH

RESTORE VALIDATE, then what?

Hi,
Everyday I do,
LIST BACKUPSET SUMMARY COMPLETED AFTER...
VALIDATE BACKUPSET XXXX,XXXX...
RESTORE VALIDATE CONTROLFILE
RESTORE VALIDATE SPFILE
RESTORE VALIDATE ARCHIVELOG FROM TIME 'XX-XXX-XX'
RESTORE VALIDATE DATABASE
1: Assuming the Server crashed, what is the quickest way to bring the database up and running, if on another server, and how to revert back to the original server.
2: I'm a bit confused as to everyday I do backup/validate, suppose I don't have a cold backup, but I've archivelog for 1 month, how do I restore/recover the database, do I need a timely cold backup as well? (current backup includes, daily incrementally updated, and weekly hot backup).

Regarding your question 2: it makes not one jot of difference whether you're doing hot, cold or tepid backups. Complete recovery always demands (a) some baseline to restore from (b) all the redo taken from the time that baseline was created until now (whenever "now" is).
If you don't backup for a month, no worries: so long as you've got one month's-worth of redo safe and available, you'll (or RMAN will) be able to restore the one-month-old backup and roll it forward to the current time by recovering it (that is, applying redo to it).
Of course, that will be slow. The purpose of taking any sort of backup (hot or cold, it's irrelevant) is to provide a baseline which is a little nearer to "now" than before, and thus to obviate the need to apply so much redo (which is generally a lot slower to do than restoring a more up-to-date backup is).
Specifically, therefore, no: you don't need "a timely cold backup as well". You just need to be taking regular physical backups of the entire database at a pace that suits your recovery needs. Your weekly hot backup is a perfectly acceptable baseline: there's no need to do cold backups unless you feel the need to do so. They are not intrinsically safer of more recoverable than a hot backup, provided only that your redo is always kept safe.

RESTORE VALIDATE possible prior to an OPEN RESETLOGS?

Is it possible to perform a RESTORE VALIDATE to a point in time prior to an OPEN RESETLOGS?

That's what I'm finding... I don't want to have to restart the database to reset the incarnation to have to test restore a backup prior to open resetlogs (no catalog only controlfile used).
"If RMAN is connected NOCATALOG, then you can only specify TO INCARNATION if the database is mounted and the control file contains a record of the prior incarnation. If you do not run RESET DATABASE, RMAN recovers to the last incarnation recorded in the control file."

So, it does validate the database. In such case, how much different it is to VALIDATE a BACKUP than saying RESTORE DATABASE VALIDATE?
I want to use RESTORE DATABASE CHECK LOGICAL VALIDATE for checking the restorability of the database but I want to know what the real difference between these two are. Seems like both are doing the same work in the background.
Will be great to know your point of view.
Thanks,

Restore database validate command

Hey Guys..
Is there a way to attempt to run the "restore database validate" command specifying a different location for the backup?
Lets say i have a backup in the following location: C:\SimpleBackup
How can i run the restore validate command to that location instead of the default flash recovery?

We always use the :
set newname for datafile 1 to '/opt/dbsid/db01/system.dbf';
set newname for datafil 2 to '/opt/dbsid/db01/temp01.dbf';
to restore backup files to another location.
Is that useable here ?
Edit: I just re-read the question. Is the c:\simplebackup a destination to put restored files to, or is it the location of the rman archive ?
if the first is true, then the above can't be used.

If I need a full rman restore which backups will it use?

Hello,
I have a database 11.1.0.7 with 8TB. Block change tracking is enabled.
At the weekend I take level 0 backup and during the week level 1 cumulative.
For some weeks the level 0 backup is failing, so I only have level 1 cumulative backups taken every week day with a 4 weeks old level 0 backup.
If I need a full rman restore which backups will it use? Will it be the last level 0 backup with the last level 1 cumulative?
I ask this because grid crontrol tells me that the recent level 1 backups input size is smaller than last week level 1 backups and in between I dont have any level 0 sucessfull backups. Shouldn't the input size of level 1 cumulative increase until the next level 0 backup ?
The grid reports:

Validating Backups Before Restoring Them
You can run RESTORE ... VALIDATE to test whether RMAN can restore a specific file or set of files from a backup. RMAN chooses which backups to use.
The database must be mounted or open for this command. You do not have to take datafiles offline when validating the restore of datafiles, because validation of backups of the datafiles only reads the backups and does not affect the production datafiles.
When validating files on disk or tape, RMAN reads all blocks in the backup piece or image copy. RMAN also validates offsite backups. The validation is identical to a real restore operation except that RMAN does not write output files.
You can monitor what RESTORE VALIDATE does.
Make precautions, so you do not damage the production DB!!!

ORA-19612: datafile 0 not restored due to missing data

Hello,
I'm testing a restore of the controlfile. The database is in archivelog mode and autobackup is set to ON. I successfully did a full backup and backup as copy database.
To test I did the following:
- note the DBID
- shutdown the database
- renamed both controlfiles:
$ mv /u02/rcat/control01.ctl /u02/rcat/control01.ctl_old
$ mv /u02/fra/rcat/control02.ctl /u02/fra/rcat/control02.ctl_old

Backup and Restore

Hello,
Can some one tel me when I restore my database from backup
and I have 3 weeks of archive logs in the database.
Will it restore all of these archive logs also ?
Just as the way I had the database before my restore ?
Also doing a restore validate from my RC backups can some tell me correct syntax to do this
and do I need to shutdown the instance to perform this check ?
Thanks..

Dont go with yours own policy involve yours managment for in housing the number of backups to drag yours database back.
It depends on yours backup policy ,how far behind you will need to restore the database , if yours closing process performed at the end of month 30th then probably to revert yours closing process you need to restore the backup till before the start of closing process.It alls depend on yours company policies ,how yours management can claim to revert back the database,there are cases where company required to revert back the database till before two days then you need to adhere retention policy for 2 days and keep at least two days backup.
In all cases there is recommneded to keep last two current day’s backup should be at hard disk (FRA flash recovery Area), oracle recommended tip is to always keep yours FRA far away from yours Database location possibly keep it at hard another hard drive, if possible keep this hard drive with separate controller.if you don’t keep any backup at hard disk then it will increase yours downtime in case of hard disk failure or any failure which should not be for a good DBA,you will have to have move last current backup from tape cartridge to hard disk (i.e. FRA) which will take x hours/mins to be restored at hard disk (i.e.FRA), keeping at least one last current backup at hard disk will save yours time from tape to hard disk. But if you keep 2 last current backup then it would be safer in case of any mishap with last current backup, you will be able to restore prior backup to last current one backup and then apply two days log for example
If you keep two last current backup at hard disk (FRA)
JAN 1
JAN 2
JAN 3<----------hard disk fail
You will restore Jan 2 backup but unfortunately yours 2nd Jan backup corrupted for any reason then you can go with 1st Jan backup, you will restore 1st Jan backup apply archive log till before the hard disk failure.
If you don’t keep last two backup just keep only last current backup ,in any case yours last current backup corrupted then again you will have to have move last current backup from tape cartridge to hard disk (i.e. FRA) which will take x hours/mins to be restored at hard disk (i.e. FRA),if you came across that tape cartridge last current moved backup also not restorable from tape cartridge then
you will go with previous current backup and apply archivelogs till before hard disk failure, think isn’t good if you save x hours/min to move backup from tape to hard disk to make yourself and yours company downtime impact for the cost of purchasing more space for backup.
Nevertheless if you can accommodate last 3 backups or more then that then I don’t think so there is any harm but don’t rely at all at yours hard disk backup, move backup also to reliable tape cartridge media.

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.

Clint,
I ran the command lines you wrote me after i placed the database in Startup MOUNT state, RMAN gave error messages that the database needs to be open:
RMAN> SQL 'ALTER TABLESPACE USERTB2 OFFLINE IMMEDIATE';
sql statement: ALTER TABLESPACE USERTB2 OFFLINE IMMEDIATE
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================

RMAN-11003: failure during parse/execution of SQL statement: ALTER TABLESPACE US
ERTB2 OFFLINE IMMEDIATE
ORA-01109: database not open
Then I ran the same command lines after I opened the database, RMAN gave error messages that "offline immediate disallowed unless media recovery enabled":
RMAN> SQL 'ALTER TABLESPACE USERTBS2 OFFLINE IMMEDIATE';
sql statement: ALTER TABLESPACE USERTBS2 OFFLINE IMMEDIATE

I am stuck again and need your help!
Thank you,

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.
Regards,
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.

URGENT - RMAN restore help needed

Hi,
I have inherited an Oracle 9i system ( 9.2.x ) that needs to have a RMAN based backup from it restored onto a different oracle server of the same version.
Thanks so much for your assistance on this.
I also forgot to mention we run Oracle on a windows 2003 server.
Well we have asubdirectory called Rman, so i figured thats whats doing the work.
The output from the backup is :
- In the exp directory :
one .dmp file
- In the Rman directory, 4 files per nightly backup, which have the format of :
<dbname>_<date>S<4 digit numer that increments each backup>P1
<dbname>_<date>S<4 digit numer that increments each backup>P2
<dbname>_<date>S<4 digit numer that increments each backup>P1
<dbname>_<date>S<4 digit numer that increments each backup>P1
On another drive I have found :
- seven .DBF files
- one .CTL file
One another drive I found :
- one .ARC file
- one .CTL file
- REDO01.LOG,REDO02.LOG,REDO03.LOG files
I also found the script that runs :
rman target / catalog xxusernamexx/xxpasswordxx@PRD_DBA01 @D:\DBA\dbaadm\scr\RmanFull.rcv >> %logfile%
Where Rmanfull.rvc is as shown below :
DELETE NOPROMPT FORCE BACKUPSET COMPLETED BEFORE 'sysdate-8' DEVICE TYPE disk;
DELETE NOPROMPT FORCE ARCHIVELOG ALL COMPLETED BEFORE 'sysdate-8' BACKED UP 2 TIMES TO DEVICE TYPE disk;
BACKUP INCREMENTAL LEVEL 0 VALIDATE database PLUS archivelog;
BACKUP INCREMENTAL LEVEL 0 TAG 'XXXXXXXX-Current' database PLUS archivelog NOT BACKED UP 2 TIMES;
BACKUP DEVICE TYPE disk TAG 'XXXXXXX-BkupSet' BACKUPSET COMPLETED BETWEEN "TO_DATE(TRUNC(sysdate-1))" AND "TO_DATE(TRUNC(sysdate))" FORMAT 'D:\ORABackup\%d\Rman\%d_%T_s%s_p%p' DELETE INPUT;
RESTORE VALIDATE database;
RESTORE VALIDATE controlfile TO 'D:\ORABackup\Null\control.ctl';
RESTORE VALIDATE spfile TO 'D:\ORABackup\Null\spfile.ctl';
I have put in XXXXXXXX to blank out some names.
I will do some reading, however what are your thoughts as to what this means for how I would do a restore of this database please? Not being lazy here, as I understand it oracle databases can get complex in configuration etc which is why i decided to ask people who do this all the time for a bit of guidance.
Thanks in advance,
Cheers

Edited by: user11915486 on 17/09/2009 22:37Hi and welcome to Forum!
I'd suggest you firstly to refer to [Administrators Guide documentation |http://download.oracle.com/docs/cd/B19306_01/server.102/b14231/toc.htm] - to have basic knowledge of Oracle database and file types. Without having this knowledge, you will not be a successful DBA
Let's analyze the script:
DELETE NOPROMPT FORCE BACKUPSET COMPLETED BEFORE 'sysdate-8' DEVICE TYPE disk;
It deletes backupsets which completed before 8 days before (From disk, not from tape)
DELETE NOPROMPT FORCE ARCHIVELOG ALL COMPLETED BEFORE 'sysdate-8' BACKED UP 2 TIMES TO DEVICE TYPE disk;
Deletes all archived redo log files which were backed up two times and completed before 8 days
BACKUP INCREMENTAL LEVEL 0 VALIDATE database PLUS archivelog;
Validates (not backups- just checks whether this script will run successfully ) the backup of database with all archived redo log files
BACKUP INCREMENTAL LEVEL 0 TAG 'XXXXXXXX-Current' database PLUS archivelog NOT BACKED UP 2 TIMES;
Backups Incremental level 0 backup of all database (which backups all the database with incremental option which will be used in the future when you'll take incremental 1 backups) and archived redo log files which not backed up 2 times and give it special Tag name to use it in the future just providing only tag name
BACKUP DEVICE TYPE disk TAG 'XXXXXXX-BkupSet' BACKUPSET COMPLETED BETWEEN "TO_DATE(TRUNC(sysdate-1))" AND "TO_DATE(TRUNC(sysdate))" FORMAT 'D:\ORABackup\%d\Rman\%d_%T_s%s_p%p' DELETE INPUT;
Backups all backupsets wich completed in 1 day (between yesterday and today) and gives it specific name and deletes original backupsets
RESTORE VALIDATE database;
Checks restoration of database (whether it is successful or not)
RESTORE VALIDATE controlfile TO 'D:\ORABackup\Null\control.ctl';
Checks restoration of controlfile
RESTORE VALIDATE spfile TO 'D:\ORABackup\Null\spfile.ctl';
Check restoration of spfile As a conclusion, I'd suggest you to refer to [Oracle Database Backup and Recovery Basics - 10g Release 2 (10.2)|http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/toc.htm] documentation to understand basics of RMAN Backup and Recovery

Restore Informix database

Hi,
I have taken the CVP's Reporting server's database. I want to restore the databse. I want help in this regard. What procedure should be followed.

>>
When I do restore validate database, in one database validate restores the last full online backup, whereas in the other it scans the datafile copies.
>>
What do you mean by datafile copies? Are you talking about RMAN image copies?
RESTORE... VALIDATE causes RMAN to select existing backups that it would use to perform a RESTORE operation, and scan them all to ensure that they are present and free of corruption.
RESTORE... PREVIEW identifies the backups which RMAN will use to perform any RESTORE operation. Output from a RESTORE... PREVIEW is in the same format as the output of the LIST command.
Oracle prefers image copies over backupsets, if exists, for restore and recovery.

RMAN restore problems

Hello,
I have an 11.2.0.1 database (archive mode) on a windows server 2003 R2 32b. The database does backups via RMAN (catalog on other server for that purpose) with NMO (legato networker) and it work fine. But we can't restore the backups. It may be a problem with the database, but it seems more a Media Manager problem. The fact is that when we try to restore, RMAn hungs waiting for recover (without any error, just stays forever until killed), and a session on our backup server remains browsing. It happens also if we make a restore validate. On the other hand, if you make a crosscheck, it works fine.
As I said, it's very strange, and I think it's an issue with the configuration of the networker, or even the server, but I post here looking for advice, or maybe someone has seen something like this before.
Any advice would be apreciate, since the only option we have now, it's to reinstall the whole server (OS and database) from a cold backup (copy of datafile,ctrl,...)
Thanks
Edited by: Naerbon on 22-mar-2011 8:11
By the way, we've made some tests:
- backup and restore with diferent versions of networker client and NMO (thought they were on latest release). Same result.
- We've created a new instance on that server, blank, and registered new in the catalog. Same, backups, but cannot restore. With this, we've discarted the database issue...
Edited by: Naerbon on 22-mar-2011 8:21

Hi,
yes, the problem was in the comunication between the Media Manager and the client. On the way to the MM, it was all ok, but in the opposite way, MM looked just for 'server' and couldn't find it. Adding the alias on the /etc/host, MM could find the 'server' as it has then 'server.domain'
As for the scrip, I'll post here the script used for duplicating the prod database on a new installed desa machine. Solved the comunication issue, it worked more than fine.
run
set until time "to_date('Mar 20 2011 23:30:00','Mon DD YYYY HH24:MI:SS')";
allocate channel ch1 type 'SBT_TAPE' parms 'ENV=(NSR_SERVER=bckservr.privada,NSR_CLIENT=origsrvr.privada, NSR_DATA_VOLUME_POOL=poolBCK)';
allocate auxiliary channel ch2 type 'SBT_TAPE' parms 'ENV=(NSR_SERVER=bckservr.privada, NSR_CLIENT=origsrvr.privada, NSR_DATA_VOLUME_POOL=poolBCK)';
DUPLICATE TARGET DATABASE TO DBSIDDES;
With this script we duplicated de database with SID DBSIDPRO in the server origsrvr, to the server destsrvr with SID DBSIDDES. We used a set until time, so we take the last cold backup make this weekend.
