Remove archivelogs

Hi all,
I removed all archivelogs using the below rman command,
delete archivelog all;after i checked with,
sql>select count(*) from v$archived_log;####
45
Please help me to remove all archives and provide some link to read about backup and recovery.

Hello,
You should Backup the Archivelog before deleting them, so you may try this:
backup
as compressed backupset
device type disk
tag 'BKP_ARCHIVE'
archivelog all not backed up
delete all input;It will Backup and remove the Backup up Archivelog.
Hope this help.
Best regards,
Jean-Valentin

RMAN - Unable to remove archivelogs from catalog

Hi
I have missing archivelogs and want to remove them from caltalog. The controlfile is beeing used as catalog. I have done the following:
CROSSCHECK ARCHIVELOG ALL;
-For the missing archivelogs RMAN output is "validation failed for archived log".
DELETE FORCE EXPIRED ARCHIVELOG ALL;
-output says:
deleted archive log
archive log filename=/an/log/autonar/archive/1_317009_555884131.dbf recid=5088 stamp=685099967
Deleted 1 EXPIRED objects
However the command does not remove the logs from catalog.
LIST ARCHIVE LOG ALL; still shows the above archive logs.
Next, i tried:
CHANGE ARCHIVELOG like '%317009%' UNCATALOG;
And the result is the same:
uncataloged archive log
archive log filename=/an/log/autonar/archive/1_317009_555884131.dbf recid=5088 stamp=685099967
Uncataloged 1 objects
But i can still see the files in the catalog.
Why is this happening? Anyone had problems like this?

The problem is in the controlfile. I'm not using the database catalog, just the controlfile.
However, I did try registrating the database on rman catalog. But the results are the same when i execute above mentioned commands.
I also tried manually removing rows from the catalog table (RMAN.AL table). This does remove the enteries from the catalog, but not from the control file. So after the next resync, the catalog gets the information back from the controlfile and i'm back to beginning. :(

Removing archivelogs

Dear buddies,
I am running out of hard disk space and trying to remove files which might not be of great use to me.
I am planning to remove the old alert logs and trace files. May be leaving the last couple of days' files.
WHat about archivelog? How could I remove them? I need to remove them using RMAN?
Please advice.
Thanks a lot.

Dear gcgeorge,
I am not using flash recovery area.
The cdump has only 1 one file and other unwanted application folders have been removed from that drive.
This is my current backup script:
RUN {
      crosscheck backup;
      crosscheck archivelog all;
      backup INCREMENTAL LEVEL 1 database format='PATH\%U_%I_%T.bkp' tag= "everyday_full_bkup"
      plus archivelog format='PATH\Arch%U_%I_%T.arc' tag=arcbkp;
      backup current controlfile;
      restore database validate;
exit
Should I be changing it like this:
RUN {
      crosscheck backup;
      crosscheck archivelog all;
      backup INCREMENTAL LEVEL 1 database format='PATH\%U_%I_%T.bkp' tag= "everyday_full_bkup"
      plus archivelog format='PATH\Arch%U_%I_%T.arc' tag=arcbkp;
      backup current controlfile;
      restore database validate;
      backup archivelog all not backed up 2 times;
      delete noprompt archivelog all backed up 2 times to device type disk;
exit

Then you need to implement a reasonable backup regimen. That needs to include (at least daily if no more often) an rman backup of your archivelogs and rman deletion of backed-up archive logs. The simplest form is
backup archivelog delete all input;but I'd STRONGLY suggest you check the Backup and Recovery manual to see the variations.
Also, while some - perhaps many - will disagree with me, I don't like putting my fra on ASM. It just feels to me like having all my eggs in one basket. But I'll also admit that while I have a couple of systems running ASM, I'm pretty new to it and just feel more comfortable with things on a regular FS.

Deletion of archivelogs

hello,
my database in archivelog mode.......
i am taking hotbackup of datafile,controlfile and archivelogs every day.
so what is the best way to remove archivelogs???
i am not taking cold backups
thanks in advance

To quote the propaganda:
"Oracle recovery makes inconsistent backups consistent by reading all archived and online redo logs, starting with the earliest SCN in any of the datafile headers, and applying the changes from the logs back into the datafiles."

Archivelogs aren't deleted

My archivelogs are filling my disk!
BACKUP ARCHIVELOG ALL;
had just told me it was complete.
DELETE ARCHIVELOG UNTIL TIME 'SYSDATE - 7';
tells me "specification does not match any archive log in the recovery catalog".
It keeps killing my database. I compress the files and move them off the disk. What should I do?
P.S. I think I know the cause of the problem started because I needed NOPROMPT in the DELETE command of my script. Instead, the script died without a YES reply? My SA compressed/moved the files as a quick fix. Now, how do I recover? I tried the "crosscheck copy" command. This allowed me to run backup. But, the archivelogs just keep building.

You could use BACKUP ARCHIVELOG ALL DELETE INPUT; to automatically remove archivelogs after the backup.
CROSSCHECK only verifies the existence of backups and updates the repository. See

Archive Logs - Relocating

Good evening to all. A little about my environment:
E-Business R12
Oracle Enterprise DB 10.2.0.4.0
Split Tiers Architecture:
Server 1 / DB Node (Redhat 5.5 32bit)
Server 2 / Apps Node
My PROD database resides on a server that roughly has the following specs (those relevant to my post):
Partitions:
/ = 1TB total space 99% used
/backup = 1.75 TB total space 35% used
/boot = 200mb
Partitions "/" and "/backup" are physically different RAID volumes but on same controller. / is a RAID 10 array of the fastest SAS drives available. /backup is a RAID 1 array of two 1TB SATA drives mirrored. I backup the PROD db instance to the "/backup" partition keeping on disk backups only a few days deep since I then backup those on disk backups to a tape library.
The purpose of my post is to seek advice in what to do to get myself out of the 99% used disk space condition on my "/" partition where the PROD db is. My archive log files are taking up 200GB. How hard would it be to relocate those files to my "/backup" partition and what effect or consequences might that have on performance since the "/backup" will have lower IO performance and what effect will this have on RMAN backups?
My database uses a PFILE so would I just change the archivelog destination there and bounce the DB? What would happen then to the archive logs on the "/" partition? Couuld I then just move those files to same destination that I specified in PFILE?

Does that 200gb represent 'a few days' worth of archivelog? It sounds like you are failing to backup and remove archivelogs as part of your backup strategy.
And why are you still using a pfile? Here is a perfect example of the advantages of spfile. You could change the archivlog destination without bouncing the database. And with proper housekeeping of your archivelogs, you wouldn't have to actually move anything. Just start writing to the new location, and the old would clean itself out over the course of a few days.

Bueno.
A nosotros nos apasado el error de que no se puede guardar los archive logs por falta de espacio en Disco. Eso pasa cuando algun proceso genera demasiadas ransacciones que necesitan ser escritas en los logs. Por esa razon se genera mucho archive log y se llena el espacio en disco.
Borra los archivelog mas viejos, y que ya los tengas en un backup y asi no habra problema te recomiendo tener un espacio en disco minimo de 50%I hope this is what you meant,

Removes archivelog older, and those who already have a backup and there will be no problem so I recommend you have a disk space minimum of 50%

Rman hot backup

hello
i am using rman hot backup script to take backup database everyday but the problem is it is working but not deleting old backup older than 2 days .
also i have question .. my database is in archive log mode and everyday about 6-7 .arch files generating in my archive directory.
it is not deleting the old files but generating new files everyday so adding up to the space.
SQL> show parameter archive
NAME TYPE VALUE
archive_lag_target integer 0
log_archive_config string
log_archive_dest string /u03/archive_logs/DEVL
log_archive_dest_1 string
also should i set dest_1 as archive location or just log_archive_dest
whats is the difference.?
my rman script is

RMAN never deletes the Backups unless there is a space pressure in the Recovery Area. Instead it marks the Backups as OBSOLETE based on Retention Policy (in your case it is 2 Days),
To confirm it SET DB_RECOVERY_FILE_DEST_SIZE to some smaller value, the RMAN will remove all the Obsolete Backups automatically to reclaim space.Be very careful with this. If you generate a LOT of archivelog files and you exceed this size, on the next archivelog switch your database will hang with "cannot continue until archiver freed". RMAN will not automatically remove anything. RMAN only removes stuff when you program it in your script.
See:
http://docs.oracle.com/cd/E14072_01/backup.112/e10642/rcmconfb.htm#insertedID4 Retention Policy (recovery window or redundancy)
things like:
set retention window and number of copies
crosscheck backup
delete obsolete <-- delete old, redundant, no longer necessary backups/archivelogs
delete expired <-- NOTE: If you manually delete files and do not execute delete expired (missing file), the DB_RECOVERY_FILE_DEST_SIZE remains the same. So, you can clean out the space and oracle will still say the location is "full".
Understand that if you also set this parameter too small and your backup recovery window/redundancy are incorrectly set, you can also exhaust the "logical" space of this location again, putting your database at risk. Your parameter could be set to 100G on a 400G file system and even though you have 300G available, Oracle will see the limit of this parameter.
My suggestion, get in a DEV/TEST environment and test to see how to best configure your environment for RMAN database backups/control file, archivelog backups also taking into consideration OS tape backup solutions. I always configure DISK for RMAN backups, then have some other tape backup utility sweep those locations to tape ensuring that I have sufficient backups to reconstitute my database - I also include a copy of the init.ora file, password file as well as the spfile backup in this location.
>
In case of Archivelogs, It is better to create and execute a Purge Job to remove Archivelogs after backup them on tape.I almost agree. I try to keep all archivelogs necessary for recovery from last full backup online. I try to keep a full backup online as well. much faster at restoring stuff instead of trying to locate it on tape.

Get redo sequence number against SCN

1 DR Server (Dataguard Configuration)
1 Reporting Server (replication is configured via oracle streams on some large tables....)
Due to shortage of disk space i need to remove archivelogs from FRA on daily basis.
My requirement is to identify which archived logs are required by capture process , so that archive logs that are not required could removed.
could not identify the relationship among all_capture and v$log_history/v$archived_log views
can get the capture process and their relevant SCN numbers from

Regarding deletion of archives from asm

Dear Gurus
I want to delete archivelogs from ASM and want to schedule a script for same in crontab.Please tell me the way for same.
Also i removed archives manually from asmcmd.But when i runned below command,i didn't observed any change in the free_space.
select total_mb,free_mb,(total_mb-free_mb) used from v$asm_diskgroup;
Regards

First of all: always, always include your four digit Oracle version and platform information,
Moreover, crontab is a paleolithic tool, which you don't need as there is a more powerful scheduler in both database control and the database itself.
But more importantly: One doesn't remove archivelogs using OS commands, as that will make RMAN backups don't function correctly anymore.
You need
delete obsolete archivelog all
in RMAN
Doing so, the RMAN catalog in your controlfile and the OS will be consistent.

Archilog database problem

Hi all,
I met a problem of my database, i cannot connect to the database because the archive dest is full and cannot create archivelog file. My problem is i can't remove the archive log as it's on ASM disk group, could you please help what can i do to bring my database up.
I'm trying the ASMCMD command but not sure if i can remove archivelog by command line to make available space
Here is some details of my database
Archivelog dest: +ASM_DG1/abdb/ (ASM)
and i do the ls command there i found too many archive log. Can i delete them please or what can i do ?
Please help urgently

RaitsarevoHi Raitsarevo
If you have taken backup of all archived redo log files after full backup of the database, then you don't need those backups and they should be deleted
You can use RMAN to delete backups as well
Be sure that you've the backup of all archived redo log files. Then connect to RMAN and issue the following commands:
crosscheck archivelog all;
delete obsolete;

Is this RMAN script ok?

Hi all, I'm now approching RMAN and I wrote this script for the backup of my database (9.2.04 on Win2k3):
report schema;
show all;
configure channel device type disk format 'e:/oracle/test/2_%d_%T_%u.bus';
configure maxsetsize to 12000 M;
configure controlfile autobackup format for device type disk to 'e:/oracle/test/filename_%F.bak';
backup database plus archivelog;
backup current controlfile;
DELETE ARCHIVELOG UNTIL TIME='SYSDATE-3';
I can see that there is a problem in this script but I don't know how to solve it. The problem is that I delete the archived logs even if the backup database command doesn't end with success. Is it possibile to modify this script so that it will remove the archived logs only if the backup process ends with success?
Thank you very much.

Hi,
your script have to be depended on your environment.
You should configure a channels for backup once and make only necessary changes in configuration thought the script.
This is example of real backup script of large system
-- reconfigure for 4 TAPES backup
CONFIGURE DEVICE TYPE 'SBT_TAPE' PARALLELISM 4;
-- crosscheck for unavailable copy of archivelog and controlfile
crosscheck copy of archivelog all;
crosscheck copy of controlfile;
-- backup archive logs for minimize time of backup up database
backup
format='%d_%U'
FILESPERSET=5
archivelog
until time 'sysdate'
delete input;
-- not needed auto backup control file because we make full backup
CONFIGURE CONTROLFILE AUTOBACKUP OFF;
-- backup database
backup
INCREMENTAL LEVEL=0
database
format='%d_%U'
FILESPERSET=2
skip READONLY
skip offline
plus archivelog
delete input;
-- bold strings point your attention to remove archivelog after backup
-- PLZ Read documentation Recovery Manager Reference
-- restore configuration for every hours archivelog backup
CONFIGURE DEVICE TYPE 'SBT_TAPE' PARALLELISM 2;
CONFIGURE CONTROLFILE AUTOBACKUP ON;
-- delete expired backup from RMAN catalog
crosscheck backup completed before 'SYSDATE-24';
delete noprompt expired backup;
quit;
For disk backup last part have to be like
delete noprompt force backup completed before time 'SYSDATE-YOUR_TIME_WINDOW_RETENTION_POLICY'.

Which archivelog files can be safely removed from OS

Hi,
I didn't used "delete input" option when backup the archivelog files. So all archivelog files still remain on the file system. How can I identily which archivelog files I can delete using the command
"RMAN>change archivelog '/u04/arch/arch_xxx.arc' delete; "
where xxx is the seq I need to make sure it's safe to be removed.
I need to make sure "restore archivelog all validate" command will still report successful afterward. The total size of archivelog files is over 20GB and I'm running out of space now. Thanks.

The only way to delete your archlog is do not do a cross check archivelog all. Bec that will invalidate your archlogs. We have a rentetion of 28 days and we dlete archlogs after everybackup using delete input. While doing cross check we use "cross check completed before 'xxx'" and then it still keeps active in repo.
