Rman full backup시 파일이 2개씩 생성 됩니다.

rman을 사용해서 cron으로 일요일 새벽마다 full backup 을 하고 있는데, 백업 볼륨 full 이 발생해서 로그를 살펴보니 아래와 같습니다.
같은 사이즈, 같은 생성 시각의 파일들이 2개씩 생성 되었습니다.
rman 백업에 별다른 작업을 하지 않았는데도 저렇게 결과가 나오니 어떻게 해야할지 감을 못잡겠습니다, 특히 아래 두껍게 표시한 줄은 로그도 좀 잘린것 같습니다.

Rman full backup issue

Hi,
The Media Management Layer GUI shows that my RMAN incremental level 0 (full) finished successfuly in the last 3 weeks.
Yet , V$RMAN_BACKUP_JOB_DETAILS shows only incremental level 1 and archive log backups :
SQL> select distinct input_type

DB INCRIt does not shows DB FULL .
What elese i can check to be sure that my Full backups are finished successfully ?
Thanks

Rman full backup, crash and full restore?

Hi,
I try to implement a simple backup and restore process with rman. Ok, with rman it's not simple. ;-)
My aim is to backup a database with a full backup and restore it from this backup, for example when it crashes.
Ok, for creating the backup I use this rman script:
run
allocate channel t1 type disk;
backup incremental level 0 format 'PATHTOBAKFILE' database;
release channel t1;
The result is a 1GB large backupfile.
Now I delete the whole database and create a new one to simulate a crash.
After this is done, I want to restore the state of the database which is frozen in the backupfile.
Therefor I use the following rman script:
run
allocate channel t1 type disk format 'PATHTOBACKUPFILE';
shutdown immediate;
startup mount;
restore database;
recover database;
alter database open resetlogs;
release channel t1;
Now rman tells me an error:
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

In english: No backup or copy of datafile X where found for restore.
I think the backup/restore possibilities with rman are very complex and I don't exactly understand which is the right backup strategie. I'm not an oracle specialist. Maybe someone can give me a hint.
My program should backup the database full, differential and incremental and also restore only by using the given backupfiles. So I want somethink like Point-In-Time recovery, but rman should use the time-point of the given backupfile. And this backupfiles are stored outside oracle, e.g. on a server or somethink like this.
Thanks a lot for help.
Best regards,
Ronny

Rman full backup and restoration

Hi,
I am planning to upgrade a oracle 10.2.0.2 RAC database to 10.2.0.4.
If i get any issues during oracle upgradation we need to revert back to 10.2.0.2 again.
I am not pretty perfect in RMAN, so please let me know
1) DO I need to take the full backup of RMAN?
2) Should I take cold backup or hot backup?
3) If my upgradation fails, how to come back to 10.2.0.2 again by using rman backup?
Thanks,
Mahi

Hi,

and what operating system are we talking about here?

If you please explain with the rman commands then that could be great help for me.

New to Oracle, why RMAN full backup has 3 backup files?

vendor set up the Oracle, but I noticed the backup has 3 files each time. not sure why.

A "LIST BACKUP" at the RMAN command line would show the contents of each of the BackupSets, BackupPieces.
When you run a BACKUP, RMAN does show, on-screen or to the log file if you redirect to a log, which datafiles are included in which BackupSet.
When you RESTORE DATABASE or RESTORE ARCHIVELOG RMAN reads the repository and identifies the BackupPieces automatically for each BackupSet . You do not need to specify them. However, if you are restoring a Controlfile, you could specifically identify where you want to restore the controlfile from -- because the default behaviour is to restore only the latest controlfile backup, but you might choose to restore an older controlfile. This can be done with the SET UNTIL clause or RESTORE CONTROLFILE FROM 'nameofbackuppiece' command.

RMAN Full Hot Backup Daily

Hi,
I have Production Database going to live this week..
this is my RMAN Backup script for taking daily Full Hot Backup night 12pm...
I have enabled FLASH_RECOVERY_AREA
DB_RECOVERY_FILE_DEST=/backup/flash_recovery_area
log_archive_dest=/backup/archivelog
log_archive_format='arch_%d_%S_%T';
=========================================================
rman target=/
configure controlfile autobackup on;
run
allocate channel c1 device type disk;
crosscheck backup;
backup as compressed backupset database;
sql 'alter system switch logfile';
crosscheck backup;
release channel c1;
exit
===========================================================
Above script is scheduled usgin cron job...
=============================================================
Here I am not taking the archive logs backup...because..by default..archive logs are created in 2 places
(a) FLASH RECOVERY AREA
(b) /backup/archivelog
so archive logs are created by date wise in Flash Recovery Area....
I have flash recovery area structure like this for ever day
/backup/flash_recovery_area/PROD/archivelog/29_09_2007
/backup/flash_recovery_area/PROD/autobackup/29_09_2007
/backup/flash_recovery_area/PROD/archivelog/30_09_2007
/backup/flash_recovery_area/PROD/autobackup/30_09_2007
Above are 2 days backups of 29th and 30th....
I can simply send those 30_09_2007 and 29_09_2007 directories to TAPE Drive....
=======================================================================
When disaster recovery, i can restore those directories to flash_recovery_area and do the recovery using rman...
=============================================
Friends...am i goin in correct way..if anything wrong...please correct me..
my doubt is..I am not used any command of backuping up archivelogs in rman script.......becasue..archive logs are created in flash_recovery_area by date wise......
am i correct..

Hi,
Thanks for the reply,
My requirement is......Full Hot Backup daily at 2 AM......Daily i have to take this...so i scheduled this using cron job......I need to maintain 7 days backup in backup location.....
Here is my script
# Export Environment Variables
export ORACLE_HOME=/oradata/oracle
export ORACLE_SID=PROD
export PATH=$PATH:$ORACLE_HOME/bin
# RMAN Full Backup
rman target / catalog rman/rman << EOF
configure controlfile autobackup on;
configure retention policy to redundancy 7;
run
crosscheck backup;
backup as compressed backupset database;
sql 'alter system switch logfile';
backup as compressed backupset archivelog all;
backup as compressed backupset current controlfile;
crosscheck backup;
crosscheck archivelog all;
delete noprompt obsolete;
delete noprompt expired backup;
exit=============================================================
Can u please verify that, script is good or not

Still need to do full backup after using data guard?

In our system, there is a physical standby database in data guard configuration. Is there still a need to do full backup and incremental backup?

Jackliusr wrote:

May be you can perform failover of your standby, in case there is no availability on primary database. Then do you think the standby system stability is same as primary and can give same performance?
standby location can be too far and this is only if in case of disaster.
Another case, lets suppose your standby is behind than primary for 4-5 days due to some issues. At the same time your production crashed then you may have chance to loose 4-5 days fo data. So recommended to have full backup always from primary database.
If you are checking stability of standby database daily and able to check your data by opening properly and you wont prefer to RMAN backup, Then it is fine. But it is highly recommended to have RMAN backup.
BTW, You can have RMAN full backup on standby, if you want to avoid resources to use on primary

Recover from full backup

Hi,
I want to recover a tablespace from a RMAN full backup. Now the related schema has many truncated objects (in a bach process), so normal tablespace restore, recovery won't help. Have to go for TSPITR. But the time I can't fix. Is there any other way to recover the tablespace other than point-in-time recovery ?

Hi Hemant,
When I run the TSIPTR recovery I am getting error,
RMAN> run {

Cloning DB on a different server from RMAN Tape backup

RDBMS version           : 11.2.0.2 on Solaris 10
Media Management Layer : Netbackup v7
I have done only backups to Tape. I have never done restore,recovery from Tape.
We have a production DB named NEHPROD running on server qualmh214. Every Monday morning an RMAN Full backup for NEHPROD is taken to Tape.
Production server : qualmh214        DB Name:NEHPROD
run
ALLOCATE CHANNEL c1 TYPE 'SBT_TAPE';
SEND 'NB_ORA_CLIENT=qualmh214,NB_ORA_POLICY=qualmh214_rman,NB_ORA_SERV=qualmh238,NB_ORA_SCHED=Daily';
backup database   FORMAT 'NEHPROD_%d_%U_%t.rbk' tag='NEHPROD_full';
}I need to create a Test DB in a different server (qualmh199) by restoring directly from NEHPROD's Full backup in tape .
From qualmh199, how can I connect to the Tape Media server ?
Even If I do connect to the Tape media server, how can i get access to tape backups of another DB? In the RMAN run block you can't specify a DB name. Right?
Even if I get access to another DB's backup , How can i specify which Date's Full backup I need to use to restore ?

From qualmh199, how can I connect to the Tape Media server ?You have to allocate channels to tape & need to mention NB parameters as example below.
in RMAN script
ALLOCATE CHANNEL CH1 DEVICE TYPE SBT_TAPE PARMS 'SBT_LIBRARY=/usr/openv/netbackup/bin/libobk.so64';
SEND 'NB_ORA_SERV=<server.com>, NB_ORA_CLIENT=<target.server>';
Even If I do connect to the Tape media server, how can i get access to tape backups of another DB? In the RMAN run block you can't specify a DB name. Right?If the libraries are installed and you able to perform, you can go for either duplicate database or simple RMAN restore. You can mention other DB names also
Ex: duplicate target database to 'test';
Even if I get access to another DB's backup , How can i specify which Date's Full backup I need to use to restore ?You can mention TAG's if you are using RMAN restore.

RMAN full DB restore on New Host

Hi There,
My RMAN full backup script is like this:
RMAN> CONNECT TARGET *
CONNECT CATALOG *
run {
allocate channel 'dev_0' type 'sbt_tape'
parms 'ENV=(OB2BARTYPE=Oracle8,OB2APPNAME=db1,OB2BARLIST=Off-site,OB2BARHOSTNAME=db1.blah.tr)';
backup incremental level 0
format 'Off-site<db1_%s:%t:%p>.dbf'
cumulative
database;
backup
format 'Off-site<db1_%s:%t:%p>.dbf'
archivelog all;
backup
format 'Off-site<db1_%s:%t:%p>.dbf'
current controlfile;
EXITCan you help writing a full restore/recover script...
Thanks

RMAN - Is it possible to run Archivelog Backup while Full backup is running

Hi,
Our full database backups runs daily in the night. It fails whenever an archivelog backup kicks off. This happens on our big databases where backups run for long hours and we have to run the archivelog backup to backup/delete the archivelogs to maintain the archivelog destinations.
Is there any way to run these 2 backups in parallel without both failing. We use RMAN catalog to take backups, and we get errors when resyncing of catalog happens during backup.
We get these errors:-
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03008: error while performing automatic resync of recovery catalog
RMAN-20033: control file sequence# too low
and sometimes
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03008: error while performing automatic resync of recovery catalog
ORA-00230: operation disallowed: snapshot control file enqueue unavailable
Our archivelog destinations are not big enough to hold more than 1 days of logs and we have backups that runs for 30 hours. We have to backup and delete the archivelogs in between, while the full backup is running and right now its failing with able errors. Is there any solution or workaround I can opt for in this scenario.
Any help is Highly appreciated. Thanks in advance for the Help.
Thanks,
Vish

Your primary issue is SPACE. Allocate sufficient space to keep at a MINIMUM 4 days worth of archivelogs ONLINE.
Use multiple channels
you will need to test your system to see where you get optimal throughput.
Use compression
you will need to test your system to see where you get optimal throughput.
Use disk-disk backups (and sweep to tape later)...
If RAC, 11gR2 - consider ACFS (stored in ASM as well as OS accessible).
Anything less and you could be issuing the command "alter dba update resume".
Database management is not something that should be approached lightly... If you don't have the resources - maybe you need to trim the data or if the business requires that data volume, then the business needs to allocate sufficient resources to stay in business. Catastrophic database failures and the businesses ignorance on the importance of their data is a huge contributor business failures. At one point (not sure of the latest figures) if a business suffered such a data loss, they rarely stayed in business for more than a year.
Storage is MUCH cheaper and the proper configuration and allocation of those resources than a company failure.

Keeping ARCH and Deleting FULL backups on RMAN

Dear all,
RMAN deletes all my full backup and archivelogs in 2 days with;
DELETE NOPROMPT OBSOLETE RECOVERY WINDOW OF 2 DAYS;
But I want to keep archivelogs at least 9 DAYS and delete just the FULL backups after 2 DAYS. How can i set this?
Any recommendations?
Regards

You reported the Sybrand's post as an "abuse to consider" to the mod. Not to take a part or the other, but Sybrand made several points you should yourself to consider up front :
1. you claimed your problem as an emergency case, it is considered as rude in a public forum based on volunteers.
2. also you did not provided any information which can make difference, as the minimum of Oracle version (and OS...), for one who want to be considered as an emergency, that's rather strange, no one here is sitting next to you
3. Sybrand gave you a command to run that you should see the suggestion resulted
4. He also made a point about the documentation, whether it can appears rude to you, it's always, ALWAYS, good to show exactly to your peers what you have done so far to solve your problem, based on what docs...
5. We could also point you a link such as How to ask question
Please, keep it in mind, and come down.

PS: without saying that 2 mods spent their time to proceed with your faulty reported abuse case

Does RMAN trigger checkpoint before a full backup?

Hello,
My test as follows:
1 insert some data to a table
2 backup full database using rman
3 shutdown abort
4 delete all datafiles(including redo logs)
5 restore and recover database
6 the inserted data can still be found.
I think RMAN triggers checkpoint before a full backup,but I can't verify it,can someone help me?
SQL> select * from v$version;

Thanks.

Dear user!
As Mr. Baker already stated in his very friendly way RMAN fires a checkpoint before a backup. You may verify it like that:
1.) Use v$datafile_header to get the checkpoint_time of an arbitrary datafile. In my example I've used datafile number 8.
SELECT file#, name, TO_CHAR(checkpoint_time, 'dd.mm.yyyy HH24:MI:SS') as checkpoint_time
from   v$datafile
where file# = 8;
     FILE#
NAME
TO_CHAR(CHECKPOINT_
         8
/u01/app/oracle/oradata/ORCL/myts1000_01.dbf
17.06.2009 06:58:312.) Export your NLS_DATE_FORMAT environment variable like that:
set NLS_DATE_FORMAT='DD.MM.YYYY HH24:MI:SS'3.) Start RMAN and backup datafile number 8
BACKUP DATAFILE 8;
Starten backup um 17.06.2009 06:58:29
Kontrolldatei der Zieldatenbank wird anstelle des Recovery-Katalogs verwendet
Zugewiesener Kanal: ORA_DISK_1RMAN will show the time when it started the backup.
4.) Query again v$datafile_header like you did in step 1.
SELECT file#, name, TO_CHAR(checkpoint_time, 'dd.mm.yyyy HH24:MI:SS') as checkpoint_time
from   v$datafile
where file# = 8;
     FILE#
NAME
TO_CHAR(CHECKPOINT_
         8
/u01/app/oracle/oradata/ORCL/myts1000_01.dbf
17.06.2009 06:58:31As you can see the last checkpoint_time of datafile 8 is near to the startingtime of the backup.
I hope that's what you wanna know.
Yours sincerely
Florian W.

Rman level 0 backup, how to confirm its full backup or not?

I am performing the level 0 full rman backup on daily basis and i am aware this backup make the base to incremental backup i.e level 1.
When i looked into object_type from v$backup_status, its show label of DB_INCR for level 0 full backup or even same status from EM. My boss suspect we are not taking full backup. Is there any way to prove or confirm, whether backup copies are full backup or not? Pls advise.

Hi,
I use the following sql to check levels and speed.
select backup_type,
incremental_level,
round(sum(output_bytes)/1024/1024,2) "MB",
status,
min(start_time),
max(completion_time),
round((sum(output_bytes)/1024/1024)/((max(completion_time)-min(start_time))*86400), 1) "MB/s"
from v$backup_set_details
group by backup_type, incremental_level, status, session_key, session_recid, session_stamp
order by 5

RMAN Incremental Lvl 0 backup vs Full Backup

Hi all professionals,
If my RMAN backup script did not specify the incremental backup strategy, what is the default strategy it would adopt?
say for example: backup as compressed backup set database plus archive log delete input;
Will it use full backup or lvl 0 incremental backup?
There is a RMAN script (similar with the above) running as scheduled job daily and I will also use backup exec to backup the database to tape (manually scheduled to run for each time but not daily) at the same time.
Will the scheduled daily rman script backup affect the scn of the backup using backup exec so that it could not be restore the tape backup using backup exec to a testing db as usual?
(checked that backup exec also use rman script to backup but it uses incremental lvl 0)
Welcome your professional comments and sharing.
Thanks,
Calvin

The only difference between a level 0 incremental backup and a full backup is that a full backup is never included in an incremental strategy.
