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

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.

Delete archivelogs with rman

I have this setting on one database: 10.2.0.3 on linux x86
CONFIGURE RETENTION POLICY TO REDUNDANCY 2;
When a backup occurs, i issue the following at the end:
delete noprompt obsolete device type disk;
Which delete an old backup and old archivelogs on the server.
Situation: It happen rarely, but still, sometimes, I have to manualy delete archivelogs to make space.
Here is what i do: Ensure that the archivelogs which I am about to delete are backed up.
Then I issue the following Rman command:
crosscheck archivelog all;
delete noprompt expired archivelog all;
which tells Rman that the archivelogs are not on the os anymore.
Is there a way to delete archivelogs with rman or oracle, not manually on the os?
note: i do not want to delete a backupset will doing so.
This is temporary solution. More disk space is comming and new backup scenario will be in place for this database.

Exists many ways to make this, as:
DELETE NOPROMPT FORCE COPY OF ARCHIVELOG ALL COMPLETED BEFORE 'SYSDATE-1';
or
BACKUP ARCHIVELOG all DELETE ALL INPUT;
or
BACKUP ARCHIVELOG all NOT BACKED UP 2 TIMES DELETE ALL INPUT;
...

When can you delete archivelogs with RMAN

My database is running in archivelog and I am using RMAN to back up the database to a SBT device (tape). The question that I have is if I do backup database plus archivelogs and this backupset is wriiten to tape can I then delete the arhivelogs from disk? On the same note when I do incremental backups can I then delete all archivelogs on disk if the backupset set is written to tape.
Thanks All!

Thanks All!Yes, and you should let rman manage that. Go to the Fine Backup and Recovery Manual at tahiti.oracle.com and check out these options for BACKUP
archivelog delete input
archivelog delete all input
archivelog delete all not backed up n times
and several other similar options.

How to delete archivelog with RMAN in the Primary and Standby database?

Hello,
I am working on Oracle 10gR2.
My question is :
How could I implement a automatized and secure way of:
1) Delete archivelogs on my PRIMARY server only when these logs are successfully TRANSFERED to all my standby databases?
2) Delete archivelogs on my STANDBY server only when these logs are sucessfully APPLIED to the database?
Thanks a lot for your help!

Skip deleted archivelog backup RMAN

Hi
I have a database in which I want to backup all the archive logs generated during the last 24 hours.But two or three archive logs generated during that period where deleted accidentally..Now if I give the command to backup archive log generated during 24 hours,wiil the backup complete successfully?

Now if I give the command to backup archive log generated during 24 hours,wiil the backup complete successfully?What happens when you try it ? You could test this in a test database with 4 hours of archivelogs if you would rather not backup production archivelogs.
The RMAN documentation has commands that help -- e.g. CROSSCHECK and DELETE. Lookup those commands.

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 would recommend you to backup these archives and then delete them.

When to delete archive logs- using rman 10.1.0.5

Hello,
I am using rman to backup my database(10.1.0.5) along with backing up the archivelogs delete input. The retention of the backup is set to 1. I am backing the datafiles and archivelogs to disk /backupdata. I noticed that the /backupdata is filling up with a lot of backup archivelogs. Since the retention of the database is set to 1, does that mean that rman will also clean the archivelogs in /backupdata too? What I am asking is, since the retention is set to 1, does rman automatically determine witch archivelogs in the /backupdata to delete if rman determines that the archivelogs is not needed to satisfied the retention 1 condition??? Thank you in advance.

rman won't automatically purge your backups. Retention policy can be defined to be 1 (what?) redundancy copies or recovery window?
You may have defined, let's say 1 redundant copy, which means you must have at least one backup to consider the other obsolete, and you will keep one redundant copy. The other backups are not automatically deleted, they are just marked obsolete, and you can delete them.
I suggest you to manually purge your backups, as they will fill up your storage. issue, from a recovery manager session:
rman> report obsolete;
rman > delete noprompt obsolete;
rman> report obsolete;
The delete noprompt obsolete will physically purge all backups reported as obsolete by the first command. You can confirm actions from the last command.
I suggest you to perform a periodic task to purge obsolete backups, schedule last command, it can be done once your regular backup ends.
If you have Enterprise manager DB Control console enabled, it can be scheduled using the internal scheduler, and it can be monitored from within EM.

Delete archivelogs on a manual standby with RMAN

Hi,
Using Oracle 10.2.0.3 Standard Edition, I created a manual physical standby database with a standby controlfile. FRA is configured on both servers.
I want to use RMAN (recovery catalog in the controlfile) to delete archivelogs on the standby server using the following command:
rman target /
delete archivelog until time 'sysdate-5';
The synchronisation is monitored on a daily basis so there's no risk to delete an archivelog that is not applied.
My question: Is there a risk of corruption of the RMAN catalog (in the controlfile) in the event of a failover? I mean, will I be able to perform my RMAN backup as it becomes the primary?
Thanks
Christophe

I don't see a problem with this statement. In 10g - even when a controlfile is missing backup information for whatever reason - backups can be recataloged.

Rman-08137 can't delete archivelog because the capture process need it

When I use the rman utility to delete the old archivelog on the server ,It shows :Rman-08137 can't delete archivelog because the capture process need it .how to resolve the problem?

It is likely that the "extract" process still requires those archive logs, as it is monitoring transactions that have not yet been "captured" and written out to a GoldenGate trail.
Consider the case of doing the following: ggsci> add extract foo, tranlog, begin now
After pressing "return" on that "add extract" command, any new transactions will be monitored by GoldenGate. Even if you never start extract foo, the GoldenGate + rman integration will keep those logs around. Note that this GG+rman integration is a relatively new feature, as of GG 11.1.1.1 => if "add extract foo" prints out "extract is registered", then you have this functionality.
Another common "problem" is deleting "extract foo", but forgetting to "unregister" it. For example, to properly "delete" a registered "extract", one has to run "dblogin" first:
ggsci> dblogin userid <userid> password <password>
ggsci> delete extract foo
However, if you just do the following, the extract is deleted, but not unregistered. Only a warning is printed.
ggsci> delete extract foo
<warning: to unregister, run the command "unregister...">
So then one just has to follow the instructions in the warning:
ggsci> dblogin ...
ggsci> unregister extract foo logretention
But what if you didn't know the name of the old extracts, or were not even aware if there were any existing registered extracts? You can run the following to find out if any exist:
sqlplus> select count(*) from dba_capture;
The actual extract name is not exactly available, but it can be inferred:
sqlplus> select capture_name, capture_user from dba_capture;
<blockquote>
CAPTURE_NAME CAPTURE_USER
================ ==================
OGG$_EORADF4026B1 GGS
</blockquote>
In the above case, my actual "capture" process was called "eora". All OGG processes will be prefixed by OGG in the "capture_name" field.
Btw, you can disable this "logretention" feature by adding in a tranlog option in the param file,
TRANLOGOPTIONS LOGRETENTION DISABLED
Or just manually "unregister" the extract. (Not doing a "dblogin" before "add extract" should also work in theory... but it doesn't. The extract is still registered after startup. Not sure if that's a bug or a feature.)
Cheers,
-Michael

Do you really want to delete the above objects (enter YES or NO)?

Deleting all backed up archives using RMAN

Hi,
I used 'delete input' to delete all the archives backed up.
I am storing archives in dest1 and dest2...i.e, in two locatiions in production.

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.

Rman syntext for deleting archivelogs

I am looking for rman syntax to delete all archivelogs but leave last 30 minutes on the disk. I tried following but it did not work
delete archivelog until time ‘sysdate – 30/(24* 60)’
any help would be appreciated.
Thanks,
mkjoco

There was no error but RMAN was keep deleting extra logs that were created after the requested time. But good news is that it is working now with following command:
"delete copy of archivelog all completed before 'sysdate - 30/(24*60)';"
I found this on the net. It seems to me that RMAN was looking for first SCN time, in the log with "UNTIL TIME " but with "COPY OF" its look for file creation time.
Don't take my words this is my guess .... If someone can verify this would be nice
Thanks
