Recovery : if we have RMAN backup

Hi,
1)If we have RMAN backup then how can we recover database.
2)If we have cold backup then how can we use this backup to recover database.
I new in DBA fileld so please need guidelines.
thanks,
Brijesh

Hello,
1)If we have RMAN backup then how can we recover database.To Recover the Database it should be in ARCHIVELOG mode and you must BACKUP the Database and the Archived logs as well.
There are several cases.
If you have just to Restore and Recover the Database from the lost of the Datafiles and, you still have the Online Redologs, you may perform a Complete Recovery:
http://download.oracle.com/docs/cd/E11882_01/backup.112/e10642/rcmcomre.htm
If you lost the Online Redologs, you'll have to perform an Incomplete recovery ( or DBPITR ):
http://download.oracle.com/docs/cd/E11882_01/backup.112/e10642/rcmflash.htm#i1011846
If you lost also the Control files and/or the Parameter File, you may have to perform first additional operations to restore these files:

http://download.oracle.com/docs/cd/E11882_01/backup.112/e10642/rcmadvre.htm#CHDBEDCH
If you use Enterprise Manager you may follow these steps:

2)If we have cold backup then how can we use this backup to recover database.I think that this link may help:

Hope this help.

Which views have RMAN backup jobs information?

Hi there,
I use EM to schedule the db backup using RMAN.
I can view the jobs in the EM.
But I can not find out which views have RMAN backup jobs information in sqlplus.
like dba_scheduler_jobs.
Your advice will be appreciated.
Thanks,
SZ

Hi,
V$RMAN_STATUS - Shows the success/failure status of all recently completed RMAN jobs.
V$RMAN_OUTPUT
Displays messages reported by an RMAN job in progress
If you want to monitor then go the following :-
Monitoring RMAN Job Progress :- view V$SESSION_LONGOPS.
first Step :-
Before starting the job, create a script file (called, for this example, longops) containing the following SQL statement:
SELECT SID, SERIAL#, CONTEXT, SOFAR, TOTALWORK,
ROUND(SOFAR/TOTALWORK*100,2) "%_COMPLETE"
FROM V$SESSION_LONGOPS
WHERE OPNAME LIKE 'RMAN%'
AND OPNAME NOT LIKE '%aggregate%'
AND TOTALWORK != 0
AND SOFAR <> TOTALWORK
After connecting to the target database and, if desired, the recovery catalog database, start an RMAN job. For example, enter:
RESTORE DATABASE;
While the job is running, start SQL*Plus connected to the target database, and execute the longops script to check the progress of the RMAN job. If you repeat the query while the restore progresses, then you see output such as the following:
SQL> @longops
SID SERIAL# CONTEXT SOFAR TOTALWORK %_COMPLETE
8 19 1 10377 36617 28.34
SQL> @longops
SID SERIAL# CONTEXT SOFAR TOTALWORK % COMPLETE
8 19 1 21513 36617 58.75

Undo tablespace recovery from RMAN backup

Hi,
Lets's assume we have RMAN backup and archivelog backups, and now
my undo tablespace's disk crashed ,how can i recover?
Can i recover while database is up?
Thanks,
Kumar.

to recover UNDO tablespace from RMAN backup you must shutdown the database and start it in the MOUNT state to recover the missing files as follows
rman target /
RUN
STARTUP MOUNT;
ALLOCATE CHANNEL ch3 TYPE Disk;
RESTORE datafile 'c:\u01\prod3\undo01.dbf';
RECOVER datafile 'c:\u01\prod3\undo01.dbf';
ALTER DATABASE OPEN;
RELEASE CHANNEL ch3;
hope this will help you

Restore RMAN from different Database Rman backup

Hi Everybody
I am practicing Rman so I have one query that how to restore rman backup from another database.
For Example :
1. I have Rman backup of DB1 with level 0 and level 1 cumulative database plus archievelog
2. I need to import or restore Rman backup of DB1 to another database DB2.
What is the procedure for doing the above queries. Please anyone one help me out.
I have using oracle 10g r2 running in windows server 2003.
Thanks in advance.

These are the steps ; you need to write the appropiate commands for each step: Hope it helps!
1) Take appropriate RMAN backup of the database db1. Note that you should turn on the CONTROLFILE AUTOBACKUP configuration so that we have the controlfile backed up after the database backup. When we restore the controlfile on new host from this autobackup piece, it will have the information of the latest backup.
2) Create a PFILE for the destination database db2 using the database db1
3) Move the backup pieces and the modified INIT.ORA file to the new host. Starting from 10g it is NO longer compulsory to copy the RMAN backup pieces to exactly the same location on the new host as the production location.
4) Use the pfile created above to STARTUP NOMOUNT the database on the new host
5) Now invoke RMAN and restore the controlfile specifying the location where the controlfile autobackup piece is restored on this new server. You can mount the database once the controlfile is restored successfully.
6) You can skip this step if you have restored the RMAN backup pieces to exactly the same location they were backed up on database db1. If this is not the case then you need to catalog the RMAN backup pieces to make RMAN aware of thier new location on the new host. Note that CATALOG BACKUPPIECE command is available only starting from 10g.
7) Having determined the point up to which media recovery should run, start the restore/recovery using for example:
RMAN> run {
2> set until sequence 59 thread 1;
3> set newname for datafile 1 to '/new_location/system01.dbf';
4> set newname for datafile 2 to '/new_location/undotbs01.dbf';
5> set newname for datafile 3 to '/new_location/sysaux01.dbf';
6> set newname for datafile 4 to '/new_location/users01.dbf';
7> restore database;
8> switch datafile all;
9> recover database;
10> }

Completeness of Prerequisites for Recovering Tables for PDBs from RMAN Backups

Could you verify the completeness of following prerequisities on pag. 441 of the "Backup and Recovery User's Guide 12c Release 1 (12.1) E17630-14"
Prerequisites for Recovering Tables and Table Partitions from RMAN Backups
■ The target database must be in read-write mode.
■ The target database must be in ARCHIVELOG mode.
■ You must have RMAN backups of the tables or table partitions as they existed at the point in time to which you want recover these objects.
■ To recover single table partitions, the COMPATIBLE initialization parameter for target database must be set to 11.1.0 or higher.
According to my test Database administrator workshop: How to recover a table in a pluggable database from a backup
those prerequisities are valid for CDBs or non-CBDs, but if you want to recover tables or table partitions in PDBs a different prerequisite is needed.
Indeed if you have a backup of only the pluggable database including the missing table (the third prerequisite above), but you don't have any backup of the container database the command...
recover table ... of pluggable database ... until scn ... auxiliary destination ...
will fail with the following errors:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of recover command at 02/12/2014 12:22:18
RMAN-03015: error occurred in stored script Memory Script
RMAN-06026: some targets not found - aborting restore
RMAN-06023: no backup or copy of datafile 3 found to restore
RMAN-06023: no backup or copy of datafile 4 found to restore
RMAN-06023: no backup or copy of datafile 1 found to restore
So to recover table in PDBs you must have also the RMAN backups of the CDB or in the opposite way it's not sufficient to have only the backups of the pluggable database, because during the creation of the auxiliary database the SYS, SYSAUX and the UNDO tablespace are required.

Hi,
Before dropping a DB we had taken an RMAN backup.I hope you were in mount mode.
Will RMAN automatically recognize the FORMAT of the backup piece and restore ?No it won't.
First you have to restore a controlfile in nomount mode with:
restore controlfile from '/u04/backup/rmanbkp /02mo9fnc_1_1';
and do alter database mount.
Than you have to run "catalog start with '/u04/backup/rmanbkp'; " so the instance now knows where to find the pieces.
Now you can run a restore database command.
Than open the database with resetlogs.

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;

whould someone help me out, how can i create database from another database rman backups with different dbname/sid on same host..
My pfile has new db_name , but while db creation rman setting to db_name to source dbname.. it should be new db name that i want create with new db name...
is there any RMAN command to specify new DB name it should set while running
sql statement: alter system set db_name = newdbname -- as part rman script execution...
it appears to be i should not touch the soruce db.. i have access to only source db rman backups and need to create another db with different dbname/sid.. please do help...

When you performing RMAN duplicate why you making your script so complicated?
Your instance name and DB name can be different, But what is the contents in your pfile "D:\TESTDELETE\initclonedb1.ora" ? please do post
Have you started any other services related to ORACLE? check in start --> run --> services.msc any other active oracles services, Make sure you have clonedb1.
Startup in nomount
check the connectivity to target server.
SET NEWNAME FOR TEMPFILE 1 TO 'F:\app\HOME\oradata\clonedb1\TEMP01.DBF';Why you mentioning SET NEWNAME FOR DATAFILE ? You have option of db_file_name_convert/log_file_name_convert in case if your file system different in Target & auxiliary.
BACKUP LOCATION 'F:\app\HOME\flash_recovery_area\orcl\'When you have backup in same location why you are mentioning this clause?
First run duplicate from auxiliary server as
rman target sys/*****@prod auxiliary /
RMAN> duplicate target database to "db_name";
Am not sure what you are trying to do. is it 11gR1 or 11gR2?
You have option of duplicate from active database without having backup also..
here some links please check it.

Information on unknown rman backup file

Hi,
I have RMAN backup piece, and no information on this RMAN backup piece.
Is there any why to get the this backup piece information like which Oracle Database version the backup was fired on, database SID, backup timing and such.
Please help me out on this.
Regards,
Karthik Chandran

Hello,
You can find some of those information in the name of the files. Most of the time, there is the SID of the database, or the timestamp of the backup. If you have the autobackup of the controlfile, you will have the DBID which will be useful to restore.
You can also try the CATALOG command in RMAN (10g and above) to find the DBID and SID of the database that created the file. The CATALOG command itself will fail if you are not connected to the database that created the backup, but it will return you those information.
Regarding the version, it is hard to tell.
If you have an autobackup of the controlfile (filename begins with CF), then it is 9i or above.
If you have OMF files (Oracle Managed Files) , then it is 10g or above.
Hope this will help.
Regards,

Can we restore oracle 11g RMAN backups to 10g server

Hi,
I have RMAN backups (full backup)of oracle 11g database. My server was suddenly crashed due to hardware failure.
We have another Oracle 10g server. Is it possible to restore RMAN backups of 11g database to Oracle 10g server???
Thanks

I don't have 11g server ready with me. The other server running oracle 10g and I dont have rights to install oracle 11g on the 10g server. So I can not test the RESTORE/RECOVER commands.
If anyone had experience in the past, please let me know whether we can RESTORE RMAN backups of 11g database to oracle 10g server...
Thanks

RMAN BACKUP configured to asm

Vinoth here.....Hi to all
We have rman backup in our environment and rman backup location is in local server '/oracle/app/oracle/rman_backpup' like this, when i check with that physical location no backup file is found. It seems like backup is stored in asm diskgroup '+DGBACKUP'. I am confused because i saw the rman log file which is written to a file during the rman backup process, it shows the backup is available in '/oracle/app/oracle/rman_backpup'. can anyone explain hw it happens because i am new to asm environment.
Thanks in advance

RMAN backup and TSM question

We have rman backup file name contains the datetime so it is unique and easy to tell. But TSM keeps every file 4 versions, so the backup file (always 1 version because of unique name) will stay on tape forever. I have no idea about TSM, according to your experience, what is the normal solution here?

Dedicated forum for {forum:id=74}.
But quickly, in general, "DBA" and "TSM/Storage manager" need to agree on media manager use and setup the system accordingly.

Problem in recovery from RMAN backup in case of disk failure

Hi
I have Oracle 9.2.0.1.0 on Windows. Full Hot RMAN backup of database is scheduled on daily basis. I am taking backup on disks. And then i do manually copy them on tapes. If any disk failure occurs than can i recover database completely in this scenario. If tried restoing that backup on different machine as given below
set ORACLE_SID=<name>
rman target sys/<pwd>@ORACLE_SID nocatalog
startup nomount
restore spfile
create pfile from spfile
startup nomount pfile
alter database mount
restore database
Everything worked fine till above steps. Now i will execute last step.
recover database
Here it gives error:-RMAN-06054: media recovery requesting unknown log: thread 1 scn 264750
Still i typed
alter database open resetlogs
Now i can open my database, But is it recovered completely? Or there is loss of some data? Why it is giving this error?
Thanks in advance. Waiting for reply.

I can understand the confusion with this whole concept.
What I meant by all archivelogs is all the archivelogs that were backed up with the backup itself. Again, it is essential to ensure that you archive the current redo log AFTER the backup is performed and then back those archivelogs too. Good thing is, RMAN will take care of this for you if you backup the archivelogs with the BACKUP DATABASE command and/or backup the archivelogs AFTER you run the BACKUP DATABASE command.
Once you've mounted the controlfile and CATALOG the archivelogs, you can go into SQL*Plus and issue the following query:
select SEQUENCE#, FIRST_CHANGE#, NEXT_CHANGE# from v$archived_log
order by FIRST_TIME;This will tell you what archivelog is the latest. Logs generated during the backup may also provide the necessary information. Performing Disaster Recovery should help to understand the full process.
The ONLINELOG directory in FRA is only populated if you've configured your redo logs to be stored there. However, you are on 9i...right? If so 9i doesn't utilize a FRA.

RMAN backup and restore for Disaster Recovery

Hi Guys,
I am very new to Oracle and have a question about RMAN backup and restore feature. I am simulating a disaster recovery scenario by having two VMs running oracle 11g, say hosta and hostb, hosta is sort of production db and the other a disaster recovery db (one that will be made primary when disaster occurs). My goal is to backup production db using RMAN and restore it on the other machine. For some reason when I restore the db on hostb, the command restores the previous backup but not the most recent one e.g. I took a backup yesterday (09/20) and applied it to the hostb that worked fine, but when I try to apply a fresh backup from today (09/21) it always picks up the old backup. Here's a dump of the screen:

Any help will be greatly appreciated.

Thanks guys, I really appreciate all your help here. I redid everything all over again to get all the information you guys wanted. Since I noticed that more eyes are looking into this I am going to reiterate my steps one more time followed by specific answers to questions. My first backup on Host B is located under ..../restore_db/backupset whereas the subsequent one is under .../restore_db/backupset/backupset2.
I take backup on Host A using:
rman target /
backup as compressed backupset database plus archivelog;
backup spfile;
quit;
I restore the backup on Host B using:
set dbid=13732232063;
startup force nomount;
restore spfile to '/oracle/app/dev/product/11.2.0/dbhome_1/dbs/spfileforums.ora' from '/export/home/dev/restore_db/backupset/o1_mf_nnsnf_TAG20110928T171830_787gbpxh_.bkp'
shutdown immediate;
startup force nomount;
restore controlfile from '/export/home/dev/restore_db/backupset/o1_mf_ncsnf_TAG20110928T171638_787gbkxn_.bkp'
quit;
/* restart rman here */
alter database mount;
catalog start with '/export/home/dev/restore_db/backupset' noprompt;
restore database;
recover database;
alter database open resetlogs;
quit;
I take another backup on Host A using (notice no spfile backup this time):
backup as compressed backupset database plus archivelog;
quit;
I restore the database on Host B using:
alter database mount;
catalog start with '/export/home/dev/restore_db/backupset/backupset2' noprompt;
recover database;
alter database open;
quit;
Output of List Backup of database (I have done this after I recovered the second time, also note that it is referring to backupset2 which is were my second backup is stored)
RMAN> list backup of database;
using target database control file instead of recovery catalog

Need inputs on RMAN Backup n Recovery for multiple restore of clean backup

I will explain my scenario below:
We have the requirement of performance testing of our proposed production platform, for this i am asked to take RMAN backup of clean position (Say Day0 or baseline backup) and restore it multiple times for few rounds of testing. My question is after 1st restore (with set until time of day0 position) if i open the database with resetlogs, would i be able to restore same clean backup again? I am using control file in the environment instead of RMAN catalog database. What i can do to make this scenario work? I am already in preperation of setting rman catalog database.
Please suggest me the best way forward...
Many Thanks
Nukesh

Hi Asif,
I tried to make it work but seems there are still issue with my recovery, can you have a look and point out the shortcommings. i am totally lost here

Restore database to another host - I have only rman backup files

Hi all,
The PC where Oracle was installed is crashed.
I have only the RMAN backup pieces in other computer.
I want to restore/recover this RMAN backup to other PC.
I know the commands, restore database, recover database,
but I've always used these commands with rman into existing rman
user. Now, I don't have anything. I have only the RMAN backup files.
How can I restore/recover database to other PC using these files?
The steps are? create other database, create a rman user, register
the rman backup files in this new rman, and restore these files
in this new database already created with the same name?
thank you!!!!

thank you!!!!You need to perform disaster recovery. For this, follow my step by step video tutorial:
