Rman level 0

Hi I have taken RMAN level 0 backup and scheduled level1 previously. Now we have moved the old datafiles and backupset and wanted to start from level 0 again. So we are running the same script and it is not running in level 0 but looking for level 1. and throwing errors. Now the flash recovery area is empty but only having the archivelogs and we want to take level 0 freshly. following is the error i am getting.

RMAN level 0 backup

Is an RMAN level 0 backup consistent (database in MOUNT code), or inconsistent (database is open)?
-Chuck

PLease copy here the entire error stack. RMAN never gives just a sngle line error message. Its a series of error messages and looking all of them would be helpful to say something useful.
As Nayab asked, please post the db version as well.

Standby database - RMAN level 0 - Recovery catalog - OEM.

We have configured rman level 0 backup from standby database on OEM. Job is running fine, but rman is not getting connected to recovery catalog. RMAN is connecting to target control file instead of recovery catalog. I understand we need to have DG broker configured for primary and standby for RMAN to connect recovery catalog if you run from OEM. We have configured the DG broker also. DG broker configuration is woriing fine. but Still Standby is not connecting the rman recovery catalog database.
Can anyone tell me what i should check.

Catalog database is same for primary and standby. It is not working for both the version. What are all the basic check i need to do to debug the issue.
THIS IS LOG FROM OEM it is not connecting to target. instead of it is connecting to target control file.

I 'am using rman to take my backup using grid control.
The database size is around 110 GB and a full ' level 0' backup is taking around 14 hrs.
Does it take this much time??

backup or copy?
The subject line contradicts the rest of your post.
And backup and copy are two entirely different things.
copy will copy the datafile, all of it.
Also, it might not be advantageous to have parallelism > the number of instances.
You now have multiple sessions hitting the same disks.
You also would need to examine progress using gv$backup_sync_io or gv$backup_async_io and gv$session_longops.

Rman level

hi all
i would like to know the how many level of rman backup is available
increment level 0 and increment level 1 and increment level 2
how all this are differ from each other or what is the difference between this and what name we can use for instance differential incremental or cumulative incremental for level 1 and level 2
Regards

<from-documentation>
Incremental backups can be either level 0 or level 1. A level 0 incremental backup, which is the base for subsequent incremental backups, copies all blocks containing data, backing the datafile up into a backup set just as a full backup would.
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.

Rman level 1 is taking same time as level 0 in oracle 9i

Hi experts,
what is exact difference b/w incremental backup(level 1) in oracle 9i/10g,
out prod db is oracle 9.2.0.8,
we are planing to implement rman on production but we have tested one of test db,
but it has taken same time as full backup(level 0)..level 1 nothing but only changed blocks why it's taking same full backup time..
what is the main reason behind that plz help me .

Oracle 10g has block change tracking feature - a file that tracks all changed DB blocks is continuously maintained. That file enables RMAN (10g) to read only the blocks that have changes since the most recent full backup. The feature could bring huge performance improvements for incremental backups. A negative would be slightly slow down DMLs during DB operation.

RMAN level 0 and level 1 tablespace/database relationships

If I take an incremental level 0 backup of an entire database and then take a level 0 of an individual tablespace, does an incremental level 1 backup of that tablespace reference the incremental level 0 of the tablespace or of the entire database? If I change the order of the level 0 backups, does it change the reference of the tablespace's level 1?
I guess what I'm asking is does the the level 1 incremental reference the latest level 0 regardless of whether it's for the whole database or just the tablespace or does a level 1 always reference it's own level 0?
Also, if I take a level 0 of the database Sunday night, and then a level 1 of the database every night after that as well as multiple level 1s of a tablespace throughout each day, will Tuesday night's database level 1 include all of Monday's tablespace level 1s?
I just can't seem to find oracle documentation about these relationships.

Hemant K Chitale wrote:
"Database" and "Tablespace" are logical groupings for our convenience.
RMAN tracks backups at the datafile level.I think that is exactly what I was looking for. I just want to clarify my understanding.
If I run a level 0 on the database Sunday night, a database differential level 1 each night, and a level 0 on a specific tablespace each morning at 6AM followed by hourly tabelspace differential incrementals only for that tablespace, then Monday night's level 1 will be an incremental of the entire database pointing to Sunday's level 0 except for that specific tablespace for which it will be incremental from that tablespace's last level 1. Does that sound right? If so, then it sounds like to restore the entire database to its state on Tuesday at noon from media, I have to put these backups back on disk before running the RMAN restore:
- database level 0 from Sunday
- Monday night's database level 1
- Tuesday's tablespace level 0
- Tuesday's tablespace level1s from 7AM - noon
This means I can avoid putting Monday's tabelspace incrementals back right? From what I gather, the RMAN restore will put the blocks back into the datafiles at their correct SCNs, and then if there are any archive logs after that point in time, the RMAN recover will apply them. Does that all sound correct?

Rman Level 0 and Level 1

Hi Everybody
I have to schedule my rman backup in the following manner.
1. Weekly once level 0 backup has to run
2. Rest of the other days level 1 backup has to run to disk
3. In between the week if we moved all backup to some other destination, the backup schedule has to run the level 0 instead of incremental backup automatically.
Then level 1 backup follows the level 0 backup.
Can anyone help me out how to schedule this task that satisfies the above three condition.

Thanks Aman
My manager he needs like windows backup that level 0 run at once in a week and level 1 follows till end of the week if we remove the backup or moved within the week then backup folder will be empty that time level 0 has to run instead of next incremental backup.
For example: I am schedule the rman by following manner by windows schedule task with script.
1. Level 0 is scheduled at saturday only
2. level 1 is scheduled from sunday to thursday.
My manager he don't want like this. level 0 should not run by day like saturday. he wants script will check the disk if level 0 is existing or not
if existing it will replace the level 0 with new one.
if not existing it will create the new one.
Is there possible to run level 0 and level 1 in the same script.

RMAN Level 1 backup affects

O/S: Windows Server 2003
DB: Oracle 11gR2
We are in the midst of a production load process. Noticed that the level 2 backup from last night failed. Want to take a level 1 backup as soon as possible.
How will a level 1 backup affect a live system if it would done 'now' -- i.e., in the midst of a production load process?
Cheers!

The RMAN backup would not affect anything you do directly (assuming it is a hot backup). It will, however, consume quite a bit of disk and network IO, which in turn could slow most DB sessions/processes that require disk/network IO.

Rollback with rman level 0

Hello all,
I am very new to oracle and i wanted to know if i have a full level 0 rman backup (with archive log ) that i have taken today(2/9/2012 13:00 pm cst)....
and now the questions is...
is there anyway possible or is oracle is capable of rolling me back to lets say 2 days back with just my backup i have taken 2 days back??...but keep in mind i only have level 0 backup that i took today... lets say i am on version 11.2.0.1
From my understanding of rman, i can only go back up until 2/9/2012 13:00 pm cst ?? or can i go back to lets says 2/7/2012 13:00 pm cst ??

In your case RMAN alone cannot rewind back data. You would need to have older backups that the point in time needed and/or to have flasback database enabled (http://docs.oracle.com/cd/E11882_01/backup.112/e10642/flashdb.htm#BRADV180).

RMAN level 0 backup with bigfile tablespaces

We noticed that our rman backup process for PROD database is not working properly.
PROD is a 8 TB size database having two bigfile tablespaces each having more than 2 TB datafile.
PROD is a 11gR1 (11.1.0.7) RAC database with ASM storage.
We are taking weekly incremental level 0 backup for entire database and level 1 backup every day.
As per v$session_longops, the approx completion time for the two tablespaces is 5 days.
We can use "SECTION SIZE" parameter to take rman backup for bigfile tablespaces and exclude them from the level 0 backup.
However, in this case our level 0 backup wont include the two bigfile tablespaces and the daily level 1 backup will not include them.
Will you pls advise us on how to take backup in this scenario.
we have only 4TB of LUN allocated for backup and have to keep 7 days of backup on disk.
Thanks in advance !
DR

We can use "SECTION SIZE" parameter to take rman backup for bigfile tablespaces and exclude them from the level 0 backup.
How do you think that the backup will be useful if you exclude some files from level 0 or base backup? You will find difficulties or you can't restore the database in case of disaster.
Yes you can use section size parameter for paralleled big file tablespace backup.
Check below for explanation and example.

RMAN level 2 backup in Oracle 10gR2

Does RMAN in 10gR2 can only do level 0 and level 1 incremental backups now there is nothing called level 2 anymore, at least that's what the doc says.
But I took level 0 after the upgrade on sunday and today morning the RMAN script as per schedule took a level 2 backup without any error. Does this mean RMAN still supports level 2 backups.
Is my level 2 backup reliable or do I have to take another Level 0 just to be on the safe side, please advice.
-Ramki
---Duplicate post, I didn't realize that there was an exclusive RMAN group and I posted in the database general group----------

The level 2 were used until the version 9i. In the version 10g is only used options 0 and 1, as documentation.
The option 0 is used for full backups (base line), and option 1 is used for incremental backups [differential (default) or cumulative].
But the level 2 is used for compatibility with old versions and it doesn't have to generate errors.

Rman level 0 and level1 restore

Hi experts
run{
BACKUP CHECK LOGICAL AS COMPRESSED BACKUPSET INCREMENTAL LEVEL = 1 CUMULATIVE DEVICE TYPE DISK TAG='LEV1' DATABASE PLUS ARCHIVELOG;
Backup current controlfile TAG='CONTROL_LEV1';
Backup spfile TAG='SPFILE_LEV1';
Same for LEV0 instead of LEV1 --> LEV0
I am doing restore of LEV0 backup then LEV1 backup to remote server
flashback turned on primary database. I have restored DB using LEV0 on remote server
After restoring LEV0
I have copied LEV1 backup to remote server
On remote server
shutdown database
flashback daabse to scn CURRENT_SCN ;
the level 0 backup has tag of LEV0 and level 1 backup has LEV1 tag, LEV1 backups are coped to remote server
What would be next command after flashback database
i tried to do restore database but it does not seem to read from LEV1 . seems i have missed on a step
thanks

restore database from TAG='LEV1';you can't simply restore data from level 1 ,data will be restored from 0 level backup and than recovery will be perform from level 1 backup.
Read
"Incremental Backup Algorithm
Each data block in a datafile contains a system change number (SCN), which is the SCN at which the most recent change was made to the block. During an incremental backup, RMAN reads the SCN of each data block in the input file and compares it to the checkpoint SCN of the parent incremental backup. (If block change tracking is enabled, RMAN does not read the portions of the file known to have not changed since the parent incremental backup.) If the SCN in the input data block is greater than or equal to the checkpoint SCN of the parent, then RMAN copies the block.
One consequence of this mechanism is that RMAN applies all blocks containing changed data during recovery—even if the change is to an object created with the NOLOGGING option. Hence, making incremental backups is a safeguard against the loss of changes made by NOLOGGING operations.
