Database Recover Using RMAN

Dear All(s)
Recently i am managing oracle 10.2.0 database, and doing database coloning and data dumping. Also doing full backup trrough RMAN. Now i want to know what happend if i take only RMAN backup, full and incremental, and how recover it.
1. How i can recover database if i loose entire server machine (in case i have only RMAN backup)
2. How i can build full database using RMAN backup on another server.
Thanks
Waiting for response

+1. How i can recover database if i loose entire server machine (in case i have only RMAN backup)+
If you loose entire server machine its just like the same you make disaster recovery or restore database to another machine.
+2. How i can build full database using RMAN backup on another server.+

Backup set in the tape. copied into disk. how to recover using RMAN

I have backup set in the tape. copied into disk. how to recover using RMAN
any link and steps please

It should be something like the following, but really you should read and understand the rman documentation first ...
1. restore the controlfile
sqlplus / as sysdba
startup nomount
exit
rman
connect target /
restore controlfile from '/path to the controlfile backup piece';
exit
sqlplus / as sysdba
alter database mount
exit
2. catalog the backup pieces
rman
connect target /
catalog start with '/path to backup pieces';
3. restore the database
rman
connect target /
restore database
4. recover the database
rman
connect target /
recover database
5. open the database
sqlplus / as sysdba
alter database open resetlogs;

Problem in performing multiple Point-In-Time Database Recovery using RMAN

Hello Experts,
I am getting an error while performing database point in time recovery multiple times using RMAN. Details are as follows :-
Environment:
Oracle 11g, ASM,
Database DiskGroups : DG_DATA (Data files), DG_ARCH(Archive logs), DG_REDO(Redo logs Control file).
Snapshot DiskGroups :
Snapshot1 (taken at 9 am): SNAP1_DATA, SNAP1_ARCH, +SNAP1_REDO
Snapshot2 (taken at 10 am): SNAP2_DATA, SNAP2_ARCH, +SNAP2_REDO
Steps performed for point in time recovery:
1. Restore control file from snapshot 2.
     RMAN> RESTORE CONTROLFILE from '+SNAP2_REDO/orcl/CONTROLFILE/Current.256.777398261';
2. For 2nd recovery, reset incarnation of database to snapshot 2 incarnation (Say 2).
3. Catalog data files from snapshot 1.
4. Catalog archive logs from snapshot 2.
5. Perform point in time recovery till given time.
     STARTUP MOUNT;
     RUN {
          SQL "ALTER SESSION SET NLS_DATE_FORMAT = ''dd-mon-yyyy hh24:mi:ss''";
          SET UNTIL TIME "06-mar-2013 09:30:00";
          RESTORE DATABASE;
          RECOVER DATABASE;
          ALTER DATABASE OPEN RESETLOGS;
Results:
Recovery 1: At 10.30 am, I performed first point in time recovery till 9:30 am, it was successful. Database incarnation was raised from *2* to *3*.
Recovery 2: At 11:10 am, I performed another point in time recovery till 9:45 am, while doing it I reset the incarnation of DB to *2*, it failed with following error :-
Starting recover at 28-FEB-13

Doubts:
1. Why did recovery failed 2nd time, but not 1st time and why is RMAN looking for online redo log group_1.257.807150859 in 2nd recovery ?
3. I tried restoring control file from AutoBackup, in that case both 1st and 2nd recovery succeeded.
However for this to work, I always need to keep the AutoBackup feature enabled.
How reliable is control file AutoBackup ? Is there any alternative to using AutoBackup, can I restore control file from snapshot backup only ?
4. If I restore control file from AutoBackup, then from what point of time/SCN does RMAN restores the control file ?
Please help me out in this issue.
Thanks.

Hello experts,
I'm little newbie to RMAN recovery. Please help me in these doubts:
1. If I have datafiles, archive logs & control files backup, but current online REDO logs are lost, then can I perform incomplete database recovery ?yes, if you have backups of everything else
2. Till what maximum time/scn can incomplete database recovery be performed ??Assuming the only thing lost is the redo logs, you can recover to the last scn in the last archivelog.
3. What is role of online REDO logs in incomplete database recovery ? They provide the final redo changes - the ones that have not been written to archivelogs
Are they required for incomplete recovery ?It depends on how much incomplete recovery you need to do.
Think of all of your changes as a constant stream of redo information. As a redolog fills, it is copied to archive, then (eventually) reused. over time, your redo stream is in archivelog_1, continuing into archvivelog_2, then to 3, and eventually, when you get to the last archivelog, into the online redo. A recovery will start with the oldest necessary point in the redo stream and continue forward. Whether or not you need the online redo for a PIT recovery depends on how far forward you need to recover.
But you should take every precaution to prevent loss of online redo logs .. starting with having multiple members in each redo group ... and keeping those multiple members on physically separate disks.

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;

Database Restore using RMAN

Can I restore a oracle database with a different name using RMAN.
Say, I backup a database named orcl. Now I wanted to restore this database with a different name. Is this possible? If yes, can some one guide me through the appropriate document?
Thank you,
Santhosh

< Can I restore this Backup on to a database with a different name ...
You even have to do this, if duplicated database belongs to the same ORACLE_HOME, otherwise it could be the same name (although the databases still have different DBIDs).

Database backup using RMAN

Hello All,
I am new to RMAN.
I am trying to make some backups of my database using enterprise manager, so i choose to backup my database based on the Oracle-Suggested Backup schedule.
I got the below command from EM:
Daily Script:
run {
allocate channel oem_disk_backup device type disk;
recover copy of database with tag 'ORA_OEM_LEVEL_0';
backup incremental level 1 cumulative copies=1 for recover of copy with tag 'ORA_OEM_LEVEL_0' database;
}i have the below question:
what does the above script do ? EM will create a job that will run it daily ? how can i check this job ? where is it logged?
where and how can i check the already configured channels ? for ex: channel oem_disk_backup
what does this script do ? recover copy of database with tag 'ORA_OEM_LEVEL_0' does it recover the database?
What are the RMAN scripts (run block), to backup my database once per week (for ex on Sunday)as level 0 backup and every day as incremental level 1 cumulative backup ? Since I think that the above script will run a level 0 backup once on the first execution and then the remaining backups are level 1 Incremental backups
Thanks and regards,

Using RMAN restore the database on a new host in ASM

Hello All,
I am trying to restore a database without using RMAN database duplicate. I want to do set new name for datafile and rename log file for online logs and change database name at last using NID.
here are details
source database - APSPROD / server - X
target database - EMERALD / Server -Y
Compressed backup is copied to destination server and I am trying to restore database using RMAN. Here is my init.ora file
cat initAPSPROD1.ora
DB_NAME=APSPROD
compatible=11.2.0.3
sga_target=8G
CONTROL_FILES='+DATA_DM01/EMERALD/controlfile/cntrl01.dbf','+RECO_DM01/EMERALD/controlfile/cntrl02.dbf','+DATA_DM01/EMERALD/controlfile/cntrl03.dbf'
DB_BLOCK_SIZE=8192
db_file_name_convert=(+DATA_DM01/APSPROD,+DATA_DM01/EMERALD)
log_file_name_convert=(+DATA_DM01/APSPROD,+DATA_DM01/EMERALD,+RECO_DM01/APSPROD,+RECO_DM01/EMERALD)
DB_RECOVERY_FILE_DEST='+RECO_DM01'
DB_RECOVERY_FILE_DEST_SIZE=5500G
So from above you can see that control file should be restored to +DATA_DM01/EMERALD and +RECO_DM01/EMERALD path.
Question -
when I am trying to restore control file. It creates an ASM alias name in +DATA_DM01/EMERALD/controlfile/cntrl01.dbf',+RECO_DM01/EMERALD/controlfile/cntrl02.dbf',' and +DATA_DM01/EMERALD/controlfile/cntrl03.dbf' but It creates fully Qualified ASM Filename under +DATA_DM01/APSPROD and +RECO_DM01/
Here is output

To restore backup on different host using RMAN

Hi All,
Friend I need your help once again. I want to restore my database from the past backup to new HOST by keeping the original database intact using RMAN. Let me explain the scenario:-
Databas Version - 8.1.7
OS - Solaris 5.8
We are using RMAN with Tivoli as third party media management. I just need to restore the database from this tape library using RMAN with recovery catalog on new server. The only doubt I have is how I will make the backups of the production database whose backup has to be restored available on the new host where I have to create new database.
I will be using different file structure for the newly restored database. Do I have to create TDPO files seperately on the server on which I have to restore the database.
Please reply asap.
Regards
Harpreet Singh

You need to create a tdpo.opt file of source on the destination database. Then, allocate channel using this TDPO_OPTFILE and recover database.

Current archive log got deleted, how to recover using previous archive log?

Hi
My current log sequence #819 and it is got deleted and no choice to get it back and I have previous archived logs with sequences #814 to 818.
When I starting my database it is showing that use 'MUST USE RESETLOGS OR NORESETLOGS option for database open then I used the command

now I don't have the archive log with sequence 819, I have recover from 818. please tell me how to do it?

You probably should post to the correct forum too: Recovery Manager (RMAN)

AUXILIARY database update using full backup from target database

Hi,
I am now facing the problem with how to implement AUXILIARY database update to be consistent with the target database during a certain period (a week). I did a fully backup on our target database everyday using rman. I know it is possible to use expdp to realize it but i want to use the current fully backup to do it. Does anybody has idea or experience with that? Thanks in advance!
Regards,
lik

That's OK. If you don't use RMAN to clone your database. You can create a database just using the cold backup of the primary database simply.
Important things are
1) you must catalog all datafiles as image copy level 0 in the cloned database
RMAN> connect catalog rman/rman@rcvcat (in host 1)
RMAN> connect target sys/manager@clonedb (in host 2)
RMAN> catalog datafilecopy
'/oracle/oradata/CLONE/datafile/abc.dbf',
'/oracle/oradata/CLONE/datafile/def.dbf',
'/oracle/oradata/CLONE/datafile/ghi.dbf'
level 0 tag 'CLONE';
2) You need to make incrementals of the primary database to refresh the clone database.Make sure that you need to specify a tag for the incremental and the name of tag is the exactly same as the one used step (1).
RMAN> connect catalog rman/rman@rcvcat (in host 1)
RMAN> connect target sys/manager@prod (in host 3)
RMAN> backup incremental level 1 tag 'CLONE' for recover of copy with tag 'CLONE' database format '/backup/%u';
3) Copy the newly created incrementals (in host 3) to the clone database site (host 2). Make sure the directory must be exactly same.
$ rcp /backup/<incr_backup> /backup/
-- rcp <the loc of a incremental in host 3> <the loc of a incremental in host 2>
4) Apply incrementals to update the clone database. Make sure you provide the tag you specified.
RMAN> connect catalog rman/rman@rcvcat
RMAN> connect target sys/manager@clone
RMAN> recover copy of database with tag 'CLONE';
5) After update the clone database, then delete the incremental backups and uncatalog the image copies
RMAN> delete backup tag 'CLONE';
RMAN> change copy like '/oracle/oradata/CLONE/datafile/%' uncatalog;
*** As you can see, you can clone a database using any methods. The key is you have to catalog the clone database when you refresh it. After finishing it, then uncatalog..

Clonning Using RMAN

I am trying to clone 10g database from one windows machine to another windows machine. I am using RMAN for this purpose.
I have carried out following steps in order to do so ..
On machine - 1
1. Done alter system switch logfile thrice;
2. Shutdown Immediate
3. Startup mount
4. Then took full database backup using RMAN with controlfile autobackup on
5. On machine two I coped backup pieces to same location as that of machine 1
On machibe-2
1. Started database in nomount stage.
2. rman target /
3. restored controlfile from autobackup
4. alter database mount;
5. run{ restore database
Recover database;}
At the end of step 5 on machine-2 I am getting following error
Starting recover at 12-OCT-07
using channel ORA_DISK_1
starting media recovery
unable to find archive log
archive log thread=1 sequence=7
RMAN-00571: ===========================================================

RMAN-06054: media recovery requesting unknown log: thread 1 seq 7 lowscn 550503
RMAN>
I don't understand why RMAN is asking for online redo log when I have taken RMAN backup with database mounted.
Cant we take true cold backup using RMAN.. (true in the sense it should not ask for any recovery at the time of restoration)

Tnsname resolve failed after performing an restore using rman

I create an full database backup using rman and I want to perform an restore on another server. Steps are as follows.
1. Install the same release of oracle database and apply the same release of patches in the testing server.
2. Create an instance with the same name of original database.
3.Perform the restore using rman.
4.Create an spfile from pfile.
5.Add an new tempfile then delete the old one.
6. Shutdown the instance and restart it.
7. reconfigure the listner.
8. reconfigure the tns.
In this step it fails,saying that "TNS:listener does not currently know of service requested in connect descriptor",but if I change the servername to the original server name,it succeed.
