Thanks in advanceThere are 4 different ways at least; You didn't mentionned your OS version nor your Oracle version.
1- When creating the database using DBCA, you can choose the option to automatically backup your database: This is the easiest way.
2- Using Enterprise Manager database Control or Grid control; this is another easy way.
3- Using DBMS_SCHEDULER. You may use a detached job (check my note here: http://www.oracle-class.com/?p=2033 )
4- using crontab job.
Hope it helps!

Hi all,
I need to configure backup in Rman using the task scheduler in windows. I have placed 2 scripts 1 is batch file and 2nd is sql file with the below contents. When i ran the batch file the process is only getting logged into RMAN prompt but not executing the sql statements, how can i schedule it?
Version: 9i
OS: Windows server 2003

Need best practices PROCESS to schedule RMAN Backups.

Hi All,
I would like a suggestion on the following for RMAN Backups:
Details:
Database: - 11gR2, Size 3TB on ASM - DW database.
Like suggestions on:
1) What kind of backups to schedule - Incremental along with Block backups?
2) Size required to allocate for the Backup Space - Can it be ASM or Disk Space?
3) Anything else - please suggest.
Thank you.

For that size, you might do weekly L0 and daily L1 (differential) backups. Try to do L1 (cumulative) backups if possible.
Getting the total sizes of Segments (from DBA_SEGMENTS) will give you an approximation for the minimum size. (Tables/Indexes that have been dropped and are no longer in DBA_SEGMENTS wouldn't appear but the underlying blocks for them if unused by other Tables/Indexes would still be backed up as they'd have been formatted).
You could run the Backup as a COMPRESSED BACKUPSET to reduce the size.
Whether you want ASM or FileSystem depends on your comfort level. If you run backups to ASM, you can only use RMAN to backup from ASM to Tape. However, backups on FileSystem can be copied to tape using any other method (tape backup utility). Also consider if you want to replicate/copy the backups to other servers and what methods you'd have available.

How to schedule RMAN backup

Hi experts,
I need to schedule automated RMAN backups in 10G(RMAN database) and i need to include the support for Oracle 8i, 9i and 10g database backups.
Any type of suggestions are welcome.
Thanx in Advance,
Senthil

Hi,
Where do you want to backup to? Do you want to backup to disk or to tape drive? Many of the tape drive softwares does have the capability of scheduling the jobs. If you want to backup to disk, then you can use your OS scheduling features.
Before all of that, you will need to write and test indivudual scripts to backup and restore.

Problem with .cmd/batch file, while scheduling RMAN backup

I am running Oracle 10g on Windows. I Have written RMAN Backup script & saved it as .cmd file. Now i will schedule this via AT utility on windows. While i try to run this .cmd file then after starting RMAN it does nothing, neither RMAN gets connected to target database nor backup gets started. What may be the problem??
Contents of .cmd file are like this:-
RMAN target 'sys/manager@test'
backup database include current controlfile;
backup archive log;

RMAN target 'sys/manager@test'
backup database include current controlfile;
backup archive log;will not work. You are passing 3 different commands to the Windows command interpreter. CMD executes the first command 'RMAN target ...@test" and waits for it to complete before it will proceed to attempt to execute the "backup database".
That is, the "backup database" command isn't being passed to RMAN at all.
You should put the two "backup" commands in a script file (as you would do for an SQLPlus script file) -- eg backup.rmn and execute it with rman
eg
rman target 'sys/manager@test' @backup.rmn

Scheduling rman backup dbconsole

Hi all,
I'm using oracle10g dbconsole for backup database in incremetal mode, but I want to do full backup database on weekend. The problem is I'm using bakcup facilitie from oracle dbconsole. I only can shedule backup for 1 day and repeat, but I can't exclude weekends for incrementally backup. Is there any form to schedule in "week day" format like crontab ??
Thanks a lot.

As Deepak said you can plan a backup strategy defining one or more Full (as part of a backup strategy) and several incremental (depending from your stratgey and requirements) directly from dbconsole.
Check custom backup and in the planning page choose Every Week.
then will appear the day list and you can choose when you want to execute your job.

Can we schedule rman backup in windows platform??

My question is about my backup settings
the idea is to all on windows platform
a complete weekly backup (compressed backupset level 0)
a daily (comulative) incremental backup (same, level 1)
a hourly (differential) incremental backup (level1)
could you please tell me if the following examples will fit my needs,
thanks to you all

this scenario i wanna createYour certainly can if you choose to do so.
I think most people are content with a inc 0 once a week, an inc 1 the other 6 days. Daily backup of archivelogs, with deletion of archivelogs after 'n' backups. It really all depends on your service level (time to recover) requirements.

How to stop a rman backup in progress?

OS: AIX 5.3 L and Oracle 10g R2
I got panic when my scheduled rman backup (incremental level 0 plus archivelog) run too long and I want to stop the process. I could not find the rman doc mentioning how to use any rman command to do that, instead of just shutdowning the database instance.with ps -ef, there were just too many PID of oracle. Is there a way by rman to STOP the process?
Furthermore, I had no idea why it happened. Last week when I did a full copy backup, it only took 23 minutes for 32G database, Today, I changed the scheme to a level 0 incremental, and it is still running after 5 and half hours. But it already created the archivelog, datafile backupset (checked by the DB control). How to find out what went wrong?

I did not use any third party application with rman or TSM in my AIX. what is the tdpo? Killing at OS level is probably only thing I can do now. kill -9 PID#

How to ensure the rman backup is successful?

Hi,
we have scheduled rman backup jobs.
1. But how do we ensure all the rman backups are successful?
2. if the rman writes directly to tape, how do we ensure all tape backups are successful?
thanks
andrew

But what is incremental merge, couldn't find in the 10g manual?check it out on http://download.oracle.com/docs/cd/B28359_01/backup.111/b28270/rcmquick.htm#BRADV89354
do you use image backup in real production environment?Of course. We have a standard to to use image copies that way.
what do you suggest to do with rman normal way of backup or go for image backup?Depends on your specific situation. Like anything else, I prefer to provide some rationale on the recommendation.
Image Copies with Incremental Merge
Pros:
(1) one one full backup taken ever; no need to take another full backup
(2) the restore time is the same, regardless of the day of the week the db failed
(3) every day the incremental merge's success means the backup was good - an automatic validation
(4) it allows you to quickly switch to copy, rather than restore
Cons:
(1) Space requirement is more (since it's a bit to bit copy)
(2) can't do a point in time recovery from the disk alone
(3) can't go to the tape directly; must be a disk based backup.
Backupsets with Incremental Backup
Pros:
(1) space requirement is lower (since only never-used blocks are not copied)
(2) point in time recovery is possible
(3) direct backup to tape possible (no need for disk backup)
Cons:
(1) restore time varies depending on the day of the week the db failed
(2) you have to take a full backup regularly, perhaps once a week
(3) no validation unless you use validate backupset (takes resources)
So, as you can see, there are pros and cons to each approach. You have to decide for yourself which one weighs more (or less) to come to a conclusion.
Hope this helps.

Rman backup for rac by oem

Br,Hi,
DB : 10.2 and 11.2
How to schedule rman backup for cluster in OEM?How to schedule without OEM?
If one of the node failed,Is it possible to run in another node automatcially?
How to schduel export/datadump in rac by oem?
Br,
Raj

I Am not using oem, without oem you should write several scripts....
for linux hot backup(archive log enabled):
bck.sh
set ORACLE_SID=mydb
set ORACLE_HOME=....
rman target sys/.... @'.../bck.ora'
bck.ora
run
BACKUP AS COMPRESSED BACKUPSET FORMAT "..../db_%d_%T_%s_%p_%U.bak" INCREMENTAL LEVEL 0 DATABASE PLUS ARCHIVELOG DELETE INPUT FORMAT "...../archivelogBackup/arch_%d_%T_%s_%p_%U.bak";
delete force noprompt obsolete redundancy 3;
backup FORMAT '..../ctl_%d_%T_%s_%p_%U' current controlfile spfile;
And create executable job which instance_id=1 and will run your bck.sh script and create schedule for this job, when first node will down you must change instance_id attribute to second one, and be sure that all backup paths exists in all nodes.

This is a NetBackup configuration issue. The client doesn't have a policy for your monthly job/schedule. I would recommend comparing the setup of the daily/weekly vs. the monthly job.

RMAN backup job showing problems

We have scheduled RMAN backup jobs for Oracle full backups & incremental level 0 & level 1 backup. Among the recent status for jobs, I have found problems for incremental 0 backup for 2nd Dec ’13 and incremental 1 backup for 6th Dec’13. I would elaborate as below:
For 2nd Dec ’13:
The messages showing are-
RMAN-03009: failure of backup command on ORA_DISK_1 channel at 12/02/2013 01:02:41
ORA-19502: write error on file "/orabackup/rman/snlprod/data_files/7voqfb9a_1_1", block number 763264 (block size=8192)
ORA-27072: File I/O error
For 6th Dec’13:
The messages showing are-
RMAN-03009: failure of backup command on ORA_DISK_1 channel at 12/06/2013 01:12:00
ORA-19502: write error on file "/orabackup/rman/snlprod/data_files/8moqpt4r_1_1", block number 1135616 (block size=8192)
ORA-27072: File I/O error
Request you to please help me with the reason for these error messages.
I hope, my question is clear.
Please revert with the reply to my query.

Hi,
You should look at your systems logs (/var/log/messages on linux, errpt on AIX) to see which error you have exactly at the OS level.
As Sybrand_b said, it is an error while writing a block on disk, so either a filesystem full or a corrupted block on disk.
Do you have additional error message like follows?
OSD-04008: WriteFile() failure, unable to write to file
O/S-Error: (OS 112) There is not enough space on the disk

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.

Can RMAN backup and export datapump executed at the same time?

Hello,
I have several databases that I backup using RMAN and export datapump everynight starting at 6PM and end at Midnight. The backup maintenance window doesn't give me enough time for each database to run at different time. I am using crontab to schedule my backups. Since I have so many databases that need to be backed up between 6PM - Midnight, some of the export and RMAN backup scripts will execute almost at the same time. My question is can my export data pump and RMAN backup scripts run at the same time?
Thank you in advance.
John

Needs must. If you don't run expdp parallel then it doesn't use that much. If it was really killing the system then look into setting up a Resource plan that knocks that user down but this is a big step.
I woud better look into using Rman
system incrementals, and block change tracking, to minimize your RMAN time.
Regards
If your shop needs to do both simultaneously then go for it.
Chris.
PS : One of my shops has maybe 20-30 rmans and pumps all kicking off some simultaneous, some not, from 0000 to 0130. No complaints from users and no problems either. Go for it.

Schedule rman using cron job

I have scheduled a cron job to take rman backup of database everyday at 4PM. But I see that the empty backup.log file is getting generated while the script is not running. If I run the backup.sh script manually then the backup is running fine. The following are the scripts and the crontab details,
backup.sh script is as follows,
cd /u01/app/oracle/rmanbkp
rman target / <<EOF
run
allocate channel ch1 type disk format '/u01/app/oracle/rmanbkp/%d_%T_%s.bak';
backup database;
delete noprompt obsolete;
exit;
EOF
while the output of 'crontab -l' is
00 16 * * * /home/imsoracle/backup.sh > backup.log
Backup is not happening, what is wrong in my settings. Please advise.

Dear $ami Malik,
There is another option that you can use for RMAN scripting as shown below;
0 2 * * 2 export ORACLE_HOME=/oracle/product/10.2.0/db_1/ ;
/oracle/product/10.2.0/db_1/bin/rman cmdfile /db/optima/archive/OPTPROD/RMAN/backup_full.sh
log /db/optima/archive/OPTPROD/RMAN/backup_full.log
vals2:/home/oracle#cat /db/optima/archive/OPTPROD/RMAN/backup_full.sh
connect target sys/password@optprod
backup database format '/db/optima/archive/OPTPROD/backupset/DB_FULL_%d_%t_%s_%p';
backup archivelog all delete all input format '/db/optima/archive/OPTPROD/backupset/ARC_%d_%t_%s';
exit;So you can construct such backup strategy with the cmdfile and log options of the recovery manager.
Hope That Helps.
