Using RMAN to delete unwanted archivelog files..??

Hi All,
How can i remove the unwanted archivelog files from the disk, to manage the disk space usage, using RMAN?
My 10g database is in ARCHIVELOG mode and the OS is RHEL ES Release 3
when i tried with 'delete expired archivelog all;', i got the result as follows:
RMAN> delete expired archivelog all;
released channel: ORA_DISK_1
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=363 devtype=DISK
specification does not match any archive log in the recovery catalog
Please update...
Many Thanks in advance.....!!!

with the delete all input, can i assume that the archivelog files has been got deleted...Don't you trust Oracle ? :-)

I keep seeing this messages when I try to backup archive logs.
Please note that this is a standby database.
Could someone let me know why it doesn delete these ?

Hi
Please see below explanation of the APPLIED column on this view:
Indicates whether the archivelog has been applied to its corresponding standby database (YES) or not (NO). The value is always NO for local destinations.
This column is meaningful at the physical standby site for the ARCHIVED_LOG entries with REGISTRAR='RFS' (which means this log is shipped from the primary to the standby database). If REGISTRAR='RFS' and APPLIED is NO, then the log has arrived at the standby but has not yet been applied. If REGISTRAR='RFS' and APPLIED is YES, the log has arrived and been applied at the standby database. You can use this field to identify archivelogs that can be backed up and removed from disk.
If this column is not updated then that suggests your standby isn't applying logs?
Thanks
Paul

Using anonymous to delete or rename files

We have setup pure-ftpd on our Sles 10sp3 Oes2, we would like the anonymous user to be able to delete or rename files in the directory, but we cannot find any setting for this on the configuration file. The anonymous home directory is located on the NSS volume. So is it possible to configure the anonymous user to delete or rename files ?

ArchiveLog deletion using RMAN

Hi,
My backup failed for some time due to disk space issue which I was able to fix using setting db_recovery_file_dest_size but after the completion of backup script it didn't delete all the archivelog files. I still have log files from 05 Jan 2011 - 20 Feb 2011, but log files from 21 Feb 2011 - 18 Apr 2011 were deleted, When I run "crosscheck archivelog all;" it didn't show me archivelogs between 05 Jan 2011 - 20 Feb 2011 in the results but physically they are present in the archive folder.
1 How to delete these archive files to free up disk space?
2 Can I restore my database from last backup which was successful?
3 Why the RMAN was unable to delete my archivelog files?
My retention policy is set to Redundancy 1.
Thanks,
Prashanth

The older archivelogs are no longer in the control file if they are not being reported by CROSSCHECK.
Normally, when the FRA is close to 100% usage, Oracle can automatically purge known obsolete files. However, if you resized the FRA before the files were auto-purged and, subsequently, they became older than the keep time, Oracle became "unaware" of them.
You could re-CATALOG them with a CATALOG command and then DELETE them, with a DELETE command.

Hi,
Use
RMAN>crosscheck archivelog all; cmd

Regarding deletion of archivelogs.

Hello,
my database is in archivelog mode and i am taking hot backup of datafile everyday.now because of disk space i have to delete some archivelog files.
so till which date i can delete archivelogs???
thanks in advance...

Assuming you're using RMAN, you can set a retention period and just tell RMAN to delete the obsolete archived logs as part of the backup.
In general, you can delete archive logs whose maximum SCN is earlier than the earliest hot backup you want to be able to restore and roll forward. Depending on the organization and the database, different folks have very different retention periods-- some folks keep archived logs for months, others for a couple days. Of course, if you've backed up the archived logs already, you can likely delete them on disk, depending on how many copies of any particular log your recovery plan requires you to have.
Justin
Hans beat me to it.
I should also note that I'm assuming that archived logs in your environment are being used exclusively for backup & recovery purposes. You may need to keep them longer because they're required for auditing purposes, for Streams or other replication technologies, etc.

Frequency of Hot backups using RMAN

Hello.
After years of running various inhouse utilities to backup our Oracle databases we are now going to implement RMAN in our shop. We are running Oracle 10.2.0.4 EE databases on Solaris servers in Archivelog mode, so we'd like to perform "hot" backups. A caveat to this is that we also have "standby" databases that we manually manage via a series of scripts that works rather well and helps our CIO sleep at night.
So what we're trying to do is tackle one obstacle at a time. We'd like to implement RMAN hot backups (including archivelogs) without having RMAN remove the archivelog backups that are out there. We simply want RMAN to backup the archivelog files, we'll manage their movement and removal ourselves for the time being.
The script I have put together simply issues: Backup database plus archivelog format='/dumps/rman/F_Database_%d_set%s_%T_%U';
The configuration settngs (we want at least a 2 day recovery period) are:
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 2 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/dumps/rman/controlfiles/%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO BACKUPSET;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/dumps/rman/W_Database_%d_set%s_%T_%U';
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/xora01/app/oracle/product/10g/dbs/snapcf_glprd.f'; # default
We are using an RMAN catalog.
So my question is, if I perform the backup of the database (using the above command) once or twice a week and back-up only the archivelogs on a daily basis, would I be covered and save space at the same time? I think this might cover me as far as the archivelogs are concerned as well until my management is more comfortable with RMAN and allows us to install/use Data Guard.
Thanks for you opinions/suggestions...

Hi,
So my question is, if I perform the backup of the database (using the above command) once or twice a week and back-up only the archivelogs on a daily basis, would I be covered and save space at the same time? I think this might cover me as far as the archivelogs are concerned as well until my management is more comfortable with RMAN and allows us to install/use Data Guard.Your idea also not bad to save disk space. it is also depends on database size and space availability on your server.
or else you can go for weekly once fulll backup, remaining days incremental backups & archivelog backups.
rman incremental backups take only chanegd blocks so it wont occupy much space
1) sunday - full backup - level 0
2) monday - inc1 & arch
3) tuesday - inc2 & arch
4) wednesday - inc1 & arch
5) thursday - inc2 & arch
6) friday - inc1 & arch
7) saturday - inc2 & arch... & so on...
Thanks

File present after deleting from gallery file

This problem seems to have multiple symptoms:
I save an image over another image in the gallery, but the original image is displayed.
I delete an image file from the gallery file then save another file into the folder with the same name as the previously deleted then the deleted image is displayed when used.
I delete an image file from the gallery folder then start a new, blank, project and the image file that I deleted is available to use in the project...but the file isn't in the gallery!?
Can someone please help me figure out how to permanently remove these "ghost" files?

Indeed it isn't clear.
So I'm not sure what you are reporting here. It sounds as if you have visited the Gallery in order to delete an unwanted image, no? And on deleting an unwanted image, you create a new project and somehow see it?
For one thing, a totally new project shouldn't be using anything from the Gallery. Now there may be other content that gets added if you elected to use a Theme. Is that perhaps what's happening here?
What exactly are you seeing that you wish to wave goodbye to? A screen shot might help. To add one, use the Camera icon in the web interface to the forums. Don't try to attach to email.

RMAN hot backup requires archivelog all the time?

Hi all,
consider the case: a dml operation is running in oracle 11g database. after sometime it got completed and issued a commit statement. Now i took a full database hot backup using rman. but dint take archivelog backup(its must i know, but i want to know whether we can do incomplete recovery using only the full database backup and open database using RESETLOGS option?
Kindly let me know whether we can do incomplete recovery using only full database backup or we must need archivelog to open the database?
Regards,

Say your BACKUP DATABASE begins at 01:00am and finishes at 01:50am. At the minimum, you need to backup the Archivelogs from 01:00am to the first archivelolg after 01:50am. Technically you don't need the archivelogs of before 01:00am. However, if you want the ability to do a point in time recovery (which is a MUST for any production database), you would also backup the "earlier" archivelogs which can be used with the previous database backup.
Your commit does NOT guarantee that the database files are immediately updated -- DBWR "lazily" defers writing to the database files. Your commit is preserved in the online redo log. This has to be archived as an Archivelog and backed up.

RMAN in 10g database deletes archivelog files before standby receives them

Hi all,
We currently have problem with our Oracle 10gR1 database on Windows 2000 server in that the RMAN backups on the primary database delete archivelogs before the standby database can receive current and new archivelogs from primary database. What happens is that RMAN backs up the archivelogs and deletes them from disk before the archivelogs are sent to the standby. The standby then looks for these archivelogs on the primary but is unable to locate them. Whenever this happens, the production database (primary) hangs and we have to restart the instance on the primary. We have our Data Guard setup in maximum performance mode so this should not happen.
As a short term fix, we have changed the backups to have RMAN backup and delete the archive logs 15 minutes older than current time so that the standby can receive the logs and not have problems. Besides this fix is there a long term solution to the problem or is it a bug in Oracle 10g? The issue came up after we upgraded from 9i to 10g and never saw it before in 9i with RMAN and Data Guard physical standby databases.
Thanks
Ben Prusinski, Oracle DBA

thanks for answer...
did you managed to make it 'work'?
according to doc. if set on standby it should:
<>
Then, these files are eligible for deletion:
Archived redo log files in the flash recovery area that
were applied on the standby database.
<>
and this is to my understanding irespective to retention policy...unfortunately report obsolete does not report applied archived logs as eligable for deletion.
How this works in your case?
regards.

Delete archivelogs using RMAN

Hi,
I usually delete archivelogs with RMAN with command as "DELETE ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE -1' if i have to clear the archivelogs to freeup space from the FRA.
My question is if i delete the archivelogs-does this deletes the records from the catalog also(I think so) if backed up to tape.In that case the catalog doesn't have info for these archives even if they are on tapes,correct?
So in case of recovery how can i restore them?
Thanks
Edited by: 822424 on May 15, 2011 7:28 PM

The RESYNC CATALOG that may be part of your backup script or implicitly executed by a Backup would synchronise from the control file to the catalog schema (repository).
I don't think that you can selectively decide what to not resync.
You can query RC_ARCHIVEDLOG (the STATUS column) in the repository and in V$ARCHIVED_LOG (which is against the controlfile)
i) before the DELETE executed by RMAN and
ii) again after the next BACKUP which does a RESYNC to see if changes are reflected.
