RMAN :: 11g Archivelog Backups Not Going Obsolete?
Mar 11, 2013
We have EM (Cloud 12c) initiated scheduled backup jobs that perform (all below are online backups, obviously archivelog mode)
- level 0 Incremental 3AM on Sunday - with options backup all archive logs, delete input, delete obsolete
- level 1 Incremental (non cumulative) 3AM every other day - same options
Recovery window is set to 3 days, other options below:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 3 DAYS;
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET PARALLELISM 2;
[code]....
Everything appears to be working normally (archive logs are being backed up and once they are the archive logs themselves are being deleted from the FRA), but I'm having some trouble understanding the behavior of the delete obsolete.
With a recovery window of 3 days, on Monday at 11AM my expectation would be that I would find in backups the following:
- level 0s from day before (Sunday) and the previous Sunday (8 days prior)
- all level 1s from previous Sunday on (so Mon-Sat and this morning)
- archivelog backups from Friday until this morning
What I'm not understanding is that I'm seeing archivelog backups from last Monday, Tuesday, etc. - i would have thought these would have gone obsolete based on my recovery window, yet when I run report obsolete in RMAN nothing is showing up.

I have a problem in running delete obsolete or report obsolete using rman. Although the retention policy is set to "CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 60 DAYS;", when running delete obsolete or report obsolete it deletes or returns all the backupsets till sysdate. What should I do to solve this issue?

Oracle 10gR2 on 64-bit RHEL.Backup Strategy:There will be a level-0 backup of the database every Sunday and level-1 every weekday.Archivelogs will be backed up up every 30 minutes.
Q: How can I delete ALL the archivelog backups that were taken that day (every 30 minutes) right after successful completion of level-0 or level-1 backup?
I want to delete them because they may not be of any use after the level-0 or level-1 backup (am I right)?

We observed that our RMAN backup was taking more time to complete. CROSSCHECK is the main culprit as because of having data in the catalog for more than 3 years.
So in the part of script we added delte obsolete recovery windoe of 14 days. (Redundancey 1).
Here the problem is we are getting error as
RMAN-03002 - failure of delete command
RMAN-06091 - NO channel allocated for maintenance (of an appropriate type).
Reason: Till 2 years back the backup was stored in tape and after that it got changed to disk. So allocating channel disk to delete obsolet is not working. How we can over come this.
We tried like allocating channel tape sbt_type. It got failed as no media manager information configured. We dont have that information.
How we can overcome this.

I've created a small script witch delete the obsolete and expired backups of RMAN.
The problem is: the "delete obsolete" and the "delete expired backup" command needs a confirmation with YES. I don't need to confirm the command and he deletes the backups directly?
Here is my little script:
#!/bin/ksh
export ORACLE_SID=dbtest2
export ORACLE_HOME=/home/oracle/srv/ora/product/11.2.0/dbtest_2
export ORACLE_BIN=/home/oracle/srv/ora/product/11.2.0/dbtest_2/bin
alias RMAN=$ORACLE_BIN/rman

I have been trying to do a once off backup of an oracle database. I have followed instructions to do standard backups and when actually running the RMAN backup I got a ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode.
No problem: I read that you need to execute the following commands in RMAN to ensure a clean shutdown/startup of the database to get past this problem: run {shutdown immediate;startup mount, etc } ...problem is - this code shuts down the database and then I cannot restart it using startup mount as it starts with this TNS listener errors. So I have restart through services but then I get the NOARCHIVELOG error cropping up again.
I'm getting quite frustrated with this. I don't need an archive/redo log - I just need the current state (snapshot) of the database with all the datafiles / procedures/functions in it...a once off - but I can't seem to get this working.

I am trying to delete the backupset using Delete Obsolete command, but i am unable to get the success. As per the oracle Doc after completion of Retention Period oracle automatically deletes the backupset. I have set the retention period of 8 days.

"If no level 0 backup is available, then the behavior depends upon the compatibility mode setting. If compatibility is >=10.0.0, RMAN copies all blocks changed since the file was created, and stores the results as a level 1 backup. In other words, the SCN at the time the incremental backup is taken is the file creation SCN. If compatibility <10.0.0, RMAN generates a level 0 backup of the file contents at the time of the backup, to be consistent with the behavior in previous releases."
So yes, that's it. Even in the Oracle 11g OCP course and exam, the information given is for Oracle 9 (pre 10g). Seems like a major functional regression.
------------------------------------------------------------------------------------------------------------------------------------------------
Original problem.
Am I not understanding something about rman????
Using oracle 10g standard edition and rman.
No existing backups.
When I run repeated level 1 cumulative incrementals, the appear to back up everything (like a level 0 would).
My understanding is that if a level 1 is run w/o an existing level 0 backup, it will generate a level 0 backup.
All subsequent level 1 backups should be level 1's as expected.
If I explicitly generate an level 0, followed by level 1's it all works as expected.
I am determining what got backed up by the size of the resulting save sets.
Do I have to do an explicit level 0 and then explicit level 1's? I thought not.

if I run below rman command lines in 10g and 11g RMAN, it works well, but NOT in RMAN (Release 8.1.7.4.0), so which commandlines I should use to get to the same pursposes in RMAN 8.1.7.4?
run {
ALLOCATE CHANNEL c1 TYPE 'sbt_tape';
ALLOCATE CHANNEL c2 TYPE 'sbt_tape';
ALLOCATE CHANNEL c3 TYPE 'sbt_tape';

I have some client RMAN backups from an AIX machine, a set of .bkp files including the control file, that I have been asked to restore on a Windows 2003 server. My first question is if such a restore is possible?Also, the backups are from Oracle 10.2.0.3, and I need to restore them to 11g, will this cause any complications?
how to carry out such a restore procedure from scratch.

We just purchased NAS (Raid5) unit to manage our data storage. I am planning to create a virtual partition on this nas device and use one partition for oracle data storage and another virtual partition will be used by other data (files and may be sqlserver data files....etc..)
We will have oracle installed on seperate oracle server. Can we use RMAN to manage incremental backups in this environment? May main worry point is that our data storage device will have many different type of datas and will we be able to tell RMAN to make backups only from certain virtual drives?

RECOVER COPY OF DATABASE
WITH TAG 'incr_update';
BACKUP
INCREMENTAL LEVEL 1
FOR RECOVER OF COPY WITH TAG 'incr_update'
DATABASE;
}
taken from here [URL]....
1) Does it backup archivers? If not, how to add them?
2) Can this script be run daily for ever?

I have a standby database in which I am backing up my database from. I also backup my archivelogs on my primary site as well as the control file. My issue is that I cannot find the correct RMAN command that will allow me to delete the actual backupsets from disk after say 7 days.
I know how to delete automatically the actual archivelog files, but not how to only have 7 days of archivelog backupsets available at any one given time.

I have an environment in which backup is performed of Oracle 10/11 databases with the use of RMAN and Tivoli Storage Manager (Data Protection for Oracle).There are several databases and for every one there is a daily full backup and hourly archive logs backup.
Sometimes when full db backup takes longer (up to 4 hours) archive logs backups are missed - as TSM node cannot perform two backups at a time. I would like not to have those missed backups.
Option A was to delete association of the arch log scheduler during full backup. But when removing association we lose historical data about backup. And we need historical data to be able to create weekly / monthly / quarterly statistics of completed backups. We need to have 99% completed.
Option B was to create two nodes in TSM (TDPO) and one will do full backup only and another one only arch logs backup. So the problem is moved to RMAN. But from RMAN specialist I heard that this may cause problems with full backup. During full backup also archive logs are backed up (at the start and end) so there might be a problem with accessing the file that is used by another process. And this may cause problem with full backup - which we want to avoid especially.

RMAN is not removing obsolete backups and now the backup directory is nearly full.Retention policy is 1, however, there are backups more than 6 weeks old still in the backup directory.crosscheck and delete obsolete commands run every night, and I have also run these manually, yet the backup files still remain.It is like RMAN is not aware of their existance.How can I confirm that RMAN does not need them and therefore delete them manually using OS commands.

We have two Windows 2008 VMs with Oracle 11G configured as primary and standby.This configuration has been defined by a partner who is no longer working for us.We have broken the correct application of the redo log on the standby when we have not correctly restored some snapshots on those two VMs.I would like to create a new Oracle server that will become the new standby. For that, I need too :
- Display the full dataguard configuration to reproduce it on the new server
- Stop (delete ?) the configuration on the primary server.
We also have the current problem that RMAN refuses to delete old archivelog since they have not been applied to the standby.

I have a live server on which Oracle 10g Database is running. We take full RMAN Backups everyday. Now we want to restore the RMAN Backup file from the Live server to another machine (which is going to be a test system). I want to restore the latest RMAN backup on the test machine (which is not on network).
When I copy the RMAN backup set in the flash recovery area of the test machine and then use "list backup", the backup set is not listed. I also tried "crosscheck backup" and then "list backup" but still the backup set does not appear. how can I register the backup set from live server into test machine and then restore it.

is it possible to have a vss snapshot backup on the top of an RMAN backup. Because the link [URL] says that we can have an incremental level 1 backup on the vss snapshot backup.
So I need to know if interoperability between RMAN and VSS exists or not.
Also is it possible to have mixed backups meaning vss snapshot backups and rman backups. Whenever we take snapshot backup, is it updated in the control file?

I am trying to learn about RMAN Incrementally Updated Backups. I created a database on Server A with the parameters and configurations as shown in image attached. I would like to restore full database on Server B (Test DB).The Server B is exactly same in directory structure as the Server A
e.g. ('E:archive','E:incr_backup'). I would like to automate this process so that it updates the Server B on daily basis for R&D purpose.

I'm on a Windows server 2003 R2 64 bit, database is 11.1.0.7. From RMAN connected to the target and the catalog, this is a show all;
RMAN> show all;
RMAN configuration parameters for database with db_unique_name ORCL are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 3 DAYS;
CONFIGURE BACKUP OPTIMIZATION OFF;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO 'F:oracleadmin
[code]....
I'm running incremental backups, a level 0 on sunday and a level 1 the other days of the week, this is the ctl file:
LEVEL 0:
connect target /@ORCL
connect catalog rman/rmanpw@rmancat
RUN
{
[code]....
The level 0 does delete the archive logs (because of the delete input). Each backupset has two copies of the archive logs (which is what I want), and I expected the logs to be deleted after being backed up 2 days (each day is twice, 2 days = 4 times). But it's not deleting the logs, even after 6 runs.
