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

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!

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 job not deleting old archivelogs

I've setup an rman backup via dbconsole to backup db and archivelogs, for a retention period of 7 days, then delete obsolete. The database is 10GR2, running on windows 2008. For as yet unknown reasons, the cursed dbconsole quit working, and I haven't rebuilt it yet because I can't put this database in quiesce mode without pissing a lot of people off, so am using rman command line to check on backups etc.
I checked today, no obsolete backups found after running crosscheck database, and no obsolete logs after running crosscheck archivelog all;
Double checked recovery window and it is indeed 7 days, but there are archivelogs older than 7 days. When I run delete obsolete they dont get deleted, so I run delete archivelog all completed before 'sysdate - 7' and it deletes 314 old logs.
Why is rman not seeing these old logs? I believe I have the backups and archivelogs set to the same criteria, yet backups are being deleted over 7 days.
What am I missing here?
ps. for all the trouble dbconsole gives me, I'm tempted to go with rman scripts in windows scheduled tasks and just forget about it.. </end rant>

Hi,
How many old those archvies are?
did those archives are in your RMAN repository?
might it may be old when you have not configured retention policy..
or
delete those old archive logs once, crosscheck them all and lets see if you face any issues. still.
Thanks

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.

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.

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.

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.)

-Michael

Rman delete archivelog until time 2hrs

guys,
I want to use this inside rman.
rman{
RUN{
ALLOCATE CHANNEL ch01 TYPE DISK FORMAT 'blah lah';
BACKUP
ARCHIVELOG ALL
DELETE archivelog until time "older than 2 hrs ago" backed up 1 times to device type sbt; ;
RELEASE CHANNEL ch01;
how do i translate this "older than 2 hrs ago" to RMAN language
Edited by: user2579172 on Mar 29, 2010 1:19 PM

this served my purpose :
DELETE archivelog until time "sysdate-1/30" backed up 1 times to device type disk ;
but
rman is prompting whether to delete the archivelogs or not
ex:
List of Archived Log Copies
Key Thrd Seq S Low Time Name
4303374 1 11623
Do you really want to delete the above objects (enter YES or NO)?
Error occurred getting response - assuming NO response
released channel: ch01

HOW i heck I tell RMAN inside the run { to delete the archive logs without prompting me for YES OR NO

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;
...

Deleting Archivelogs

Hey, I am running a 11.2.0.3 RAC in archivelog mode.
I plan to modify my backup strategy.
Instead of a rman backup I just want to run a datapump export for three users of the database.
My plan:
One LEVEL 0 backup on disk, on ftp server and on local disk.
In a case of a failure I would use the fullbackup to restore the skeleton of the database. On top I would import the users from the datapump export.
I need the archivelogs, due to the fact that I have standby database in place.
Question:
If I DO NOT backup the archivelogs, will the archivelogs get deleted automatically or will the FRA run out of diskspace ?
Until now I just this command:
delete force noprompt archivelog all backed up 1 times to device type disk completed before 'sysdate -2';
I can´t use this any further right ?
Can I do this instead ?
delete archivelog until time ‘SYSDATE-2′; ????
Chris

Hey, I see the prob. With an old level 0 backup I cant´t restore until the end with the remaining archivelogs.
So, I changed my backup idea:
The plan is to backup the database once a week and keep the archivelogs for 8 days.
Instead of a daily incremental level 1 backup I would just export the users with datapump and also back up archivelogs.
All backups are transfered to a backup server.
Here my schedule:
Sun:
run {BACKUP incremental level 1 for recover of copy with tag 'Fullbackup' database plus archivelog;
recover copy of database with tag 'Fullbackup';}
Mon-Sat:
backup archivelog all not backed up 1 times;
delete force noprompt archivelog all backed up 1 times to device type disk completed before 'sysdate -8';
Does this make sense ?
Chris

How do I setup RMAN not to delete archive log files on the source database so GoldenGate can process DDL/DML changes?

I want to setup RMAN not to delete any archive log files that will be used by GoldenGate.   Once GoldenGate is completed with the archive log file, the archive log file can be backup and deleted by RMAN.   It's my understanding that I can issue the following command "REGISTER EXTRACT <ext_name>, LOGRETENTION" to enable to functionally.   Is this the only thing I need to do to execute to enable this functionally?

Hello,
Yes this is the rigth way using clasic capture.
Using the command : REGISTER EXTRACT Extract_name LOGRETENTION.
Create a Oracle Streams Group Capture (Artificial) that prevent RMAN archive deletion if these are pending to process for Golden Gate capture process.
You can see this integration doing a SELECT * FROM DBA_CAPTURE; after execute the register command.
Then, when RMAN try to delete a archive file pending to process for GG this warning appear AT RMAN logs:
Error:     RMAN 8317 (RMAN-08317 RMAN-8317)
Text:     WARNING: archived log not deleted, needed for standby or upstream capture process.
Then , this is a good manageability feature. I think is a 11.1 GG new feature.
Tip. To avoid RMAN backup multiples times a archive pending to process, there is a option called BACKUP archivelog not backed 1 times.
If you remove a Capture process that is registered with the database you need to use this comand to remove the streams capture group:
unREGISTER EXTRACT extract_name LOGRETENTION;
Then if you query dba_capture, the artificial Streams group is deleted.
I hope help.

Arturo

Step by Step RMAN configuration for full hot backup daily

Dear experts,
i am new to oracle RMAN , i have gone through couple of RMAN guides for configuration ,
i have oracle e-business suite (R12.1.1) and database is ( 11.1.0.7) on red hat enterprise linux 5.3 . All of this is 64 bit.
i have a database about 175 gb which is as usual growing day by day as data entry is taking place.
Untill now we have a cold backup strategy in the midnight 3 am a script down the database and make abc.tar.gz file of 25 gb approx. . This process takes about 100 minutes. But now due to new sales system we want our database up 24/7 .
So we want to configure RMAN hot backup.
I want to take backup on disk.
daily full hot backup.

currently database is in no-archivelog
plz help me to proceed with this .

Rman backup for rac by oem

How to schduel export/datadump in rac by oem?
Br,

I Am not using oem, without oem you should write several scripts....
for linux hot backup(archive log enabled):
bck.sh
set ORACLE_SID=mydb
set ORACLE_HOME=....
rman target sys/.... @'.../bck.ora'
bck.ora
run
BACKUP AS COMPRESSED BACKUPSET FORMAT "..../db_%d_%T_%s_%p_%U.bak" INCREMENTAL LEVEL 0 DATABASE PLUS ARCHIVELOG DELETE INPUT FORMAT "...../archivelogBackup/arch_%d_%T_%s_%p_%U.bak";
delete force noprompt obsolete redundancy 3;
backup FORMAT '..../ctl_%d_%T_%s_%p_%U' current controlfile spfile;
And create executable job which instance_id=1 and will run your bck.sh script and create schedule for this job, when first node will down you must change instance_id attribute to second one, and be sure that all backup paths exists in all nodes.

RMAN Backups for archive logs

Hi,
We are taking daily backups using BCV's and archive backup to tapes using RMAN. Please note we are using RMAN only for archive backups.
We are changing our backup strategy and I need below information on RMAN.
1) Is there any benefit I will be getting if I use RMAN for archive backups ( like finding the courruption in the logs,health of the archive) etc? Any reference note for this would be great.
2) If I use multiplexing of archives using LOG_ ARCHIVE_DEST & LOG_ ARCHIVE_DUPLEX_DEST with this I want RMAN to take the backup of archives and delete from one location only ( Say from LOG_ ARCHIVE_DEST ). And I want the archives in LOG_ ARCHIVE_DUPLEX_DEST to maintain on my own ( Like different purge strategy to zip and keep for 7 days in this location.
If I use command "backup archivelog all delete input" it is picking and removing radomly from either of these locations. Is there a way I can configure RMAN so that it will not touch my secondary locaton?
Thanks in advance.
Thanks,
Varma

You can use validate backupset command to check the health of backup.

Yes, you can do that.

You can allocate channels for that.
