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;
Regads,

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,

Backup using RMAN

Hi,
I want to perform the first backup with RMAN and I used this command and I got error:
RMAN> BACKUP AS COPY DATABASE;
can not backup or copy active file in noarchivelog mode.
But in order to turn on the log_mode to ARCHIVELOG, first I need to do shutdown the db and perform the backup. Right?
So how can I get my first backup using RMAN if the log mode is in NOARCHIVELOG mode?
I also performed controlfile autobackup on but I'm not sure the controlfiles are being backed up. How can I verify this and where I can find the controlfile backup file?
Thanks,

Hi
Yes, you must shutdown the database and set it to start in ARCHIVELOG mode.
After that you can connect to the rman catalog and the target database and execute a backup.
eg. RMAN> backup database;
You can search other example posted by me:
eg.
- Re: Backup with RMAN
- Re: How do i set up this backup strategy?
To be sure that you backed up your control file you can issue the rman-command:
RMAN> list backup of controlfile summary;

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.

Cold backup using RMAN

Dear All,
db_version :10.2.0.4
os_version:Window 2003 server
Environment:Test
I wish to perform cold backup using RMAN for the same i want to know following :
1. What is the script / command ?
2. How to restore cold backup completely ( ex:- if i lost all my data,redo and archives )
3. Is it mandatory to open the database in RESETLOG mode after recovery ( since i have a cold backup ) ?
Thanks in advance

A "Cold" Backup is called a "Consistent" Backup.
See http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup003.htm#sthref297
Backup :
From the RMAN command line :
SHUTDOWN IMMEDIATE
STARTUP MOUNT
BACKUP DATABASE
BACKUP CURRENT CONTROLFILE -- to get the controlfile in a separate backupsetRestore :
STARTUP MOUNT
RESTORE DATABASE
ALTER DATABASE OPENIf you use an SPFILE, you can have an SPFILE backup included automatically with the controlfile backupset with CONFIGURE CONTROLFILE AUTOBACKUP ON and CONFIGURE CONTROLFILE AUTOBACKUP FORMAT ...

Yes, easiest way is Enterprise Manager. Otherwise you have to define your own DBMS_SCHEDULER tasks.

Performing database backup using SAPDBA

Guys could u please let me know how to take whole database backup using SAPDBA to another hard disk attached to the system (i.e rather than taking the backupto /oracle/<SID>/sapbackup on the same system i want to take the backup to another harddisk attached to the same system?)
should i change any parameter in init<SID>.DBA?

You dont need to change the init<SID>.dba.
Rather you need to change init<SID>.sap.
make a copy of init<SID>.sap and save it as for e.g. init<SID>1.sap change the value of the following entries as follows.
backup_root_dir=your desired directory
stage_root_dir=your desired directory
Now use this init<SID>1.sap as the profile parameter file in sapdba and your backup will be stored in the"your desired directory".

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''";

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.

Validate backup using RMAN

Hi,
This is a 9i RAC environment. RMAN is used to take the backup. The database is running fine and backup is taken using cron 3 times a week. There is no error messages generated when the backup is taken.
However, in the alert log file I noticed that there are corrupted blocks in the backup files. I tried to validate the backup using (restore database validate) but I ended up with erros. Then, I tried (validate backupset) to check the corruption and I am getting different errors. 2 of the backupsets says that the data file can not be verfied. 1 of the backupset throws ORA-06510: PL/SQL: unhandled user-defined exception
Can anyone guide me with this problem?
Thank you in advance

Sorry,
but there is one big problem: you don't backup your archivelogs!
Apart from a series of redundant commands (about the only required command is 'backup database', the rest needs to be relegated to house keeping scripts), this script doesn't result in a valid backup at all!
What I do is
ORAENV_ASK="NO"
export ORACLE_SID=${DB}
. $ORAENV
case ${TRACE:-""} in
T) set -x ;;
esac
dg="`date +%a`"
case "$dg" in
Mon) LVL=0
Tue|Wed|Thu|Sat|Sun) LVL=2
Fri) LVL=1
*) LVL=2
esac
echo $LVL
exec 1>>$LOGFILE 2>&1 # redirect alle output naar de logfile
# fase 1, maak een backup van de database. Bail out als dit fout gaat
rman <<EOD
connect target ${UID}
set echo on;
run
backup incremental level ${LVL}
tag="db${TIMESTAMP}" database filesperset=1
format '${BACKUP_DIR}/${ORACLE_SID}/backup_%d_db_%T_%s_%p.bck'
plus archivelog tag="arch${TIMESTAMP}"
skip inaccessible
format '${BACKUP_DIR}/${ORACLE_SID}/backup_%d_arch_%T_%s_%p.bck'
restore database validate;
And in my case I ran
configure controlfile autobackup on, and I set the format appropiately.
The main advantage ot this code is you can always use
list backupset tag="db<yyyymmdd>"
and you don't need to think about the tag.
resync catalog is implicit with autobackup on;
Autobackup is required anyway, as the autobackup saves you from loosing the catalog.
backup database validate only ensures the database can be backed up (ie the corruption is not in the datafiles). It looks like in your case the corruption is in the backup.
Obviously, due to legal regulations, I can not post the complete script.
It is also a bit smarter than I have shown here. When this phase fails, it automatically deletes the backup, using the tag mechanism.

Script for cold backup using RMAN

Dear all,
db_version:-10.2.0.4
os_version:- Windows 2003 server
I wish to schedule a script that will take cold backup of my database using RMAN.
Any help is appreciated ..
Edited by: user12000301 on May 18, 2011 5:02 AM

Dear All,
Thanks a lot for your valuable time :
However i have managed to do it as follows :
1. First i have configure the parameter of RMAN ( Since it is my UAT in Noarchive log mode), I have never tried RMAN cold backup on the same.
Following is the out put of SHOW ALL;
RMAN> show all;
using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 2 DAYS;
CONFIGURE BACKUP OPTIMIZATION OFF;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'D:\DB\RMAN_BKP\BACKUPS%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO COMPRESSED BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1;
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT 'D:\DB\RMAN_BKP\BACKUPS\DB_%U.%r';
CONFIGURE MAXSETSIZE TO UNLIMITED;
CONFIGURE ENCRYPTION FOR DATABASE OFF;
CONFIGURE ENCRYPTION ALGORITHM 'AES128';
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'D:\DB\RMAN_BKP\BACKUPS\SNCFDB.ORA';
2. I have created a rman_cold_bkp.bat file which has following entry :
cd c:\oracle10g\bin
set oracle_sid=DB
rman target system/*** @D:\DB\RMAN_BKP\SCRIPT\rman_cold_bkp.rcv log=D:\DB\RMAN_BKP\SCRIPT\rman_cold_bkp.log
exit
3. Whereas rman_cold_bkp.rcv file contains following contents:
run
allocate channel C1 device type disk;
shutdown immediate;
startup mount;
backup database;
alter database open;
release channel C1;
exit
I did checked it and it;s working fine for me :-)

Girish
