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.

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;
...

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!

on 10G
CONFIGURE ARCHIVELOG DELETION POLICY TO [CLEAR | NONE | APPLIED ON STANDBY];

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.

Todays created archivelog backup script

Hi
i want take backup todays created archivelog.please tell me script or command
thanks

Hi,
RMAN> BACKUP ARCHIVELOG FROM TIME 'SYSDATE';
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14192/bkup003.htm#sthref365
Why after completed backup archivelog don`t you delete archivelogs?
rman> backup archivelog all delete input
after backup (exemple every night 23:59:00 - I don`t know how actually your db generates archivelog and size, in this situation, we decided backup will delay 1 minute), when you execute again, it will take new archivelogs with new date.

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 - Is it possible to run Archivelog Backup while Full backup is running

Hi,
Our full database backups runs daily in the night. It fails whenever an archivelog backup kicks off. This happens on our big databases where backups run for long hours and we have to run the archivelog backup to backup/delete the archivelogs to maintain the archivelog destinations.
Is there any way to run these 2 backups in parallel without both failing. We use RMAN catalog to take backups, and we get errors when resyncing of catalog happens during backup.
We get these errors:-
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03008: error while performing automatic resync of recovery catalog
RMAN-20033: control file sequence# too low
and sometimes
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03008: error while performing automatic resync of recovery catalog
ORA-00230: operation disallowed: snapshot control file enqueue unavailable
Our archivelog destinations are not big enough to hold more than 1 days of logs and we have backups that runs for 30 hours. We have to backup and delete the archivelogs in between, while the full backup is running and right now its failing with able errors. Is there any solution or workaround I can opt for in this scenario.
Any help is Highly appreciated. Thanks in advance for the Help.
Thanks,
Vish

Your primary issue is SPACE. Allocate sufficient space to keep at a MINIMUM 4 days worth of archivelogs ONLINE.
Use multiple channels
you will need to test your system to see where you get optimal throughput.
Use compression
you will need to test your system to see where you get optimal throughput.
Use disk-disk backups (and sweep to tape later)...
If RAC, 11gR2 - consider ACFS (stored in ASM as well as OS accessible).
Anything less and you could be issuing the command "alter dba update resume".
Database management is not something that should be approached lightly... If you don't have the resources - maybe you need to trim the data or if the business requires that data volume, then the business needs to allocate sufficient resources to stay in business. Catastrophic database failures and the businesses ignorance on the importance of their data is a huge contributor business failures. At one point (not sure of the latest figures) if a business suffered such a data loss, they rarely stayed in business for more than a year.
Storage is MUCH cheaper and the proper configuration and allocation of those resources than a company failure.

Backup archivelog all and backup archivelog in rman back

Hi,
Whats the difference between backup archivelog all and backup archivelog in rman backup.

Please find below explanation from the online documentation;
+"+
+If you specify BACKUP ARCHIVELOG ALL, then RMAN backs up exactly one copy of each distinct log sequence number. For example, if you archive to multiple destinations, RMAN backs up one copy of each log sequence number—not each copy of each log sequence number. For other commands, such as DELETE ALL does refer to every log, even duplicate log sequences.+
+"+
Hope That Helps.

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 archivelog backup fails with rman-03002,ora-19563

Hi,
D:\ Oracle- -\BIN\RMAN TARGET / NOCATALOG
RMAN> backup archivelog all;
RMAN-03002: Error with backup command on 06-25-2013
ORA-19563: Header-Validation is not successful.
fails with the given errors.
11.2.0.2 PROD DB on Windows Server 2008 R2 Enterpriise.
When I issue BACKUP INCREMENTAL LEVEL 0 DATABASE; it works fine. but with archivelog it is creating problems. Unfortunatly, I have not found exactly the same problem on google and on Oracle support.
The DB is using INIT.ORA and last time when I switched the mode to archive log mode I set the parameter like SCOPE=MEMORY as SPFILE was not in use and ALTER SYSTEM with SCOPE=BOTH FRA destination and size, but after the DB restarting of course that setting is gone and I am having these problems.
Please suggest.
Thanks a lot.
Best Regards,

Hi,
Thanks a lot.
I don't think that archivelogs were relocated, except I changed the location yesterday.
As I wrote at the start that because of INIT.ORA file being in use instead of SPFILE. I set DB_RECOVERY_FILE_DEST, DB_RECOVERY_DEST_SIZE after changing the DB mode to ARCHIVELOG, but DB was restarted by somebody else, and as the parameter changing was NOT PERMANENT, it rollback.
LOG_ARCHIVE_DEST was set to d:\oradata\db with archivelog mode but db_recovery_file_dest and size was set to 0. Now here, I have no idea that whether archivelogs were not being backed up or deleted physically, but I guess that as log_archive_dest parameter is deprecated and mode is set to archivelog with no real ARCHIVELOG DESTINATION. Please correct me if I am wrong or totally wrong :-)
I performed DELETED EXPIRED ARCHIVELOG ALL, and it deleted 49 EXPIRED objects.
Now CROSSCHECK ARCHIVELOG ALL and LIST ARCHIVELOG ALL shows nothing.
LIST BACKUP OF ARCHIVELOG ALL has of course those 49 archivelog gap.
Could you please tell the impacts of those 49 missing archivelogs. Retention policy is set to 14 days. I mean the risk is for 14 days right? As anyhow, the older backups are being DELETED according to retention policy of RMAN.

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

Backup archivelog all (RMAN)

For the first time Rman archive log backup, say for example log sequence 100 through 200 was backed.
After few days, log sequence has increased to 267, now if i run the same archive log backup command will rman backup 100 through 267 or 201 through 267. Am bit confused with this.
Help me
kumareshan

So i need to configure retention policy (Recovery window or redundancy) so that after certain period of time entry will be removed from the catalog so that RMAN will not backup the archived logs again.. Am i right??Partially.
You need to configure the retention policy AND add a instructions to delete the backuped archivelogs, with 'delete archivelog (all)'.

Delete obsolete causing issue with archivelog backups......or is it?

Hi, hoping someone will have the answer for me.
Oracle 10g R2 on Windows 2003 R2 Sever.
The start of my RMAN script runs, i do crosschecks and delete obsolete backups from type disk. My redundancy is set to 1. I then run compressed backups of the datafiles and archivelogs with 2 channels. This leaves me with two days of full backups on disk (i have months worth on netbackup) the only problem is that one of the archivelog channel backups from the previous day is missing when i know it was there before the delete obsolete was run.
here is the script:
run{
CROSSCHECK BACKUP;
CROSSCHECK archivelog all;
CROSSCHECK COPY;
CROSSCHECK backup of database;
CROSSCHECK backup of controlfile;
delete noprompt obsolete device type disk;
run {
allocate channel ch1 type disk format 'Z:\backup\rman\orcl\%d_%T_%U';
allocate channel ch2 type disk format 'Z:\backup\rman\orcl\%d_%T_%U';
backup as COMPRESSED BACKUPSET
     format='Z:\backup\rman\orcl\full_%d_%T_%U'
     tag='full_DBbackup_ris'
     database;
backup as COMPRESSED BACKUPSET
     format='Z:\backup\rman\orcl\arch_%d_%T_%U'
     tag='full_ARCHbackup_ris'
archivelog all not backed up delete all input;
sql "alter database backup controlfile to trace as ''Z:\backup\rman\orcl\controlfile_backup_trace.txt''";
release channel ch1;
release channel ch2;
This is my (simplified) list of backups on disk:
Full_day1_chan1
Full_day1_chan2
Arc_day1_chan1
Arc_day1_chan2
Full_day2_chan1
Full_day2_chan2
Arc_day2_chan1
It looks like channel2, days2, archivelog backup is missing. Is this correct? If not does anyone have an idea how to fix this?
thanks in advance.
Steven.

Hi Steven,
The data backed up by rman is written to backup pieces.
Are you missing pieces containing archive logs?
Could it be there was only 1 arc file available so the second channel could not create any backup piece?
Did you could check the output of the backup in v$rman_output?

Rman Full and Archivelog backups

I am scripting my rman stuff and it's part of a much larger Perl maintenance. I have nightly and hourly jobs. Nightly will do a full backup and hourly will do archivelog backup. Full backups take about 2-3 hours.
My question is: is there a problem with running archivelog backups be running while I am doing a full backup. If system resources are not an issues, what are some arguments for or against it?

Thanks Tychos.
That is something that I've debated - if my full would be with Plus ArchiveLog or not. So, I've decided not to backup the log during a full backup.
This is for my nightly:
open (RMAN, "| rman target sys/$SYPASS\@$CSID catalog rman/$CATPSS\@catalog >$Rlog");
print RMAN <<"END";
run {
allocate channel d1 device type disk format \'$HBDir/$HBFiles\';
set controlfile autobackup format for device type disk to \'$HBDir/$ControlFile\';
backup as compressed backupset database;
crosscheck backup;
delete noprompt obsolete;
report need backup;}
END
close (RMAN);
This is the hourly:
open (RMAN, "| rman target sys/$SYPASS\@$CSID catalog rman/$CATPSS\@catalog >$Rlog");
print RMAN <<"END";
run {
allocate channel d1 device type disk format \'$TempArchHBDir/$BUFile\';
CROSSCHECK ARCHIVELOG ALL;
set controlfile autobackup format for device type disk to \'$HBDir/$ControlFile\';
backup archivelog all not backed up 1 times delete input;
END
close (RMAN);
