Newbie.. is 'backup database plus archivelog...' needed?

On my Oracle 11.1, I'm performing full backup with command:
backup incremental level 0 database plus archivelog delete input tag LEVEL_0_INC;Since this database is not in flashback mode, I'm wondering is it needed to backup archivelogs together with datafiles?
could I done it without achivelogs and to delete them after that?

Backup database plus archivelog

Hi
I am using 10.2.0.3. What is the difference between "backup database plus archivelog" and "backup database"?
I deleted the archive logs after disabling the archive log option. How to fix the below problem? thank you

Even if you've switched your database to NOARCHIVELOG mode, the ArchiveLogs that were generated earlier are still "known" as they are still cataloged in the control file (a query on V$ARCHIVED_LOG would show them).
As you are running NOARCHIVELOG, you really do not need to do BACKUP DATABASE PLUS ARCHIVELOG;
Your backup would be in MOUNT but not OPEN state so there would be no transactions.
If you really want to "clear" those older archivelogs so that RMAN doesn't attempt to backup them, you need to run these commands in RMAN :
Crosscheck Archivelog All;
Delete Expired ArchiveLog All;The first command will verify the controlfile records against the files actually present on disk and mark as "Expired" all those they do not exist on disk. The second command will "delete" them in that RMAN will no longer look for them.

Should I keep media after "BACKUP DATABASE PLUS ARCHIVELOG"?

Hi there,
If I do full backup like this ...
BACKUP DATABASE PLUS ARCHIVELOG
... do I have to keep copy of media (database files)? I am under impression that as long as my recovery window falls between "BACKUP DATABASE PLUS ARCHIVELOG" and NOW ... I don't have to keep media files.
Am I right or wrong?
Thanks to all answers!

Sure..if you don't need to restore back to one of the previous backups, then they are no longer needed.
Configuring a retention policy will handle this maintenance for you automatically.
However, some people will keep them around as a fall back if something should happen to their most recent backup. It depends on your paranoia level and amount of disk/tape space that you have.

Error in recovery after BACKUP DATABASE PLUS ARCHIVELOG

Hi,
With Oracle 9.2.0.6 on Unix Aix 5, I made:
rman ...
RUN
ALLOCATE CHANNEL disk1 DEVICE TYPE DISK FORMAT '/base/tempora/%U';
BACKUP DATABASE PLUS ARCHIVELOG;
Copy files from /base/tempora/% to another server in a directory with the same name.
Recreate the pfile and directory structure, and then
rman...
RUN
ALLOCATE CHANNEL disk1 DEVICE TYPE DISK FORMAT '/base/tempora/%U';
restore controlfile to '/base/rcterefo/oracle/o1_mf_19xw2mvb_.ctl';
restore controlfile from '/base/rcterefo/oracle/o1_mf_19xw2mvb_.ctl';
sql 'alter database mount';
restore database;
recover database;
sql 'alter database open resetlogs';
release channel disk1;
But rman fails at -> recover database; by asking an archive log 6 months old (and not in the backupset):
ORA-00279: change 1224563589 generated at 02/09/2006 16:29:46 needed for thread

Original base seems to works fine (can be stoped and restarted).
I thought that this BACKUP DATABASE PLUS ARCHIVELOG would contain in itself all the data needed to restart the database. Database has been stopped and restarted last week with no problem and I regularly do full backup with RMAN and TSM (we are testing now backups without TSM for a spacial case).
Has someone an idea of what's wrong?
Thanks

Hi,
Thanks for taking care of my problem.
When I try to do a set until sequence..., the RESTORE CONTROLFILE fails, telling it has nothing to restore. I think this is the same kind of problem I encounter with the full restore.
Aniway, the restore being good, i try to finish the recover and it fails, asking for a very old archive. Is it possible a transaction to be active after so much time?
In fact, I just decovered a file is in RECOVER status. I did an :
alter database datafile '...' offline drop;
since that, the recover is ok, from oracle (not rman):
recover database using backup controlfile until cancel;
Thanks again to everyone.
Regards.

Hi
Run commands:

RMAN> DELETE NOPROMPT EXPIRED ARCHIVELOG ALL;
And then "backup database plus archivelog;"
Edited by: val75 on Apr 12, 2009 11:31 AM

After deleting expired archivelogs, backup is working fine...
RMAN>delete noprompt expired archivelog all;
RMAN>crosscheck archivelog all;
RMAN>backup database plus archivelog;
Actually, what is doing while issuing "crosscheck archivelog all" command????
thanks

Why Backup database then backup archivelog from time...

Dear Experts,
I found in one of our rman scripts the 2 following statements:
backup database;
backup archivelog from time 'SYSDATE -8';
It seems to me that a "backup database plus archivelog;" is more simple/accurate instead of these 2 lines as the retention windows is defined (5 days) for this DB so rman will manage the retention of datafiles and archived log, isn't it ?
Why this separate statement for the archivelog ? I find it redondant but is it...
Any advice is as usual greatly appreciated.
Best Regards,
Guillaume

You are right. The use of backup database plus archivelog; is much better and you are sure that you backup all archived log you need.
Probably that is an old script, previous version or the responsable of this script didn't know RMAN so good and the option you posted.
Bye, Aron

10g rman database and archivelogs backup with multipled archlog destination

I would like to use the 10g database and archivelogs backup statetement
backup database plus archivelog;
I would like to restrict the location of the archivelogs backed out as I am multiplexing the
archivelogs
I did not find a LIKE statement and the backup database plus archivelog
Did i miss something
patrick boulay

I meant backup
I just want to restrict rman form backing up the two location using the 'one shot' 10g syntax
I used to backup using two steps
1) datafile
2) archlogs with a LIKE expression to tell Rman where to find the archlogs
1+2 with autobackup of control+spfile
the 'backup database plus archivelog ' syntax does accept a 'LIKE' expression

Is a Level 0 Incremental the same as Backup Database?

hi experts,
This is a 10g database running in archivelog mode.
This is the backup scheme I'm currently using:
backup database plus archivelog; (runs once per day)
backup incremental level 1 database; this runs every 3 hours
(All the incrementals I make are level 1.)
In another forum, I was advised to make a level 0 incremental backup, because you cannot restore a level 1 if there was no level 0 made earlier. Now, I'm looking for the RMAN expert's advice :-)
** If I do this will I have what I need to be able to restore: **
- backup incremental level 0 database; (this will run once per day)
- backup incremental level 1 database; (this will run every 3 hours
In other words, will I miss anything if I dont do a backup database ?
Thanks, John

If you taking level 1 backup and If you dont have any level 0 then RMAN take hole database backup (level 0) with level 1 command.
It is always advisible to take level 0 and follow the level 1.
I advise to see the below doc which covers all your doubts and best way to backup.
Hope this solves your issue.

Backing up Database plus 48 hour achivelog

Hi!
I wanna create a script to backup all database files and archivelog with less than 48h (not interesting if they where previously backed up or not).
I am trying to run the folowing statement:
backup database plus archivelog from time 'SYSDATE-2' format 'E:\tmp\backup_%d_%u_%s';
But got the message:
RMAN-00558: error encountered while parsing input commands
RMAN-01009: syntax error: found "time": expecting one of: "tag"
RMAN-01007: at line 5 column 17 file: e:\tmp\backupbanco.rman
If i try the follow it works fine:
backup archivelog from time 'SYSDATE-2' format 'E:\tmp\backup_%d_%u_%s';
I think there is a stupid syntax error but i can't figure it out.
Can anyone give me a light?
Thx in advance!

OH no... Bad news! :(
Is there any alternative? It seems that:
backup database plus archivelog NOT BACKED UP SINCE TIME 'SYSDATE-2' format 'E:\tmp\database_%d_%u_%s';
Work runs ok but on the second day it will not back up again the data from previuos day...

RMAN backups in parallel, %U needed as filename ?

Hi all,
Oracle 10gR2
Flash recovery area is used for backups with RMAN.
I'd like to improve the speed of the backups.
I take full backups every night of the databases.
I'd like to use parallelism, let's say 2.
My questions is: do I have to use %U in the name of backups? So that two files are used during the backup (the same when using expdp), or it's not needed?
My scripts are like this:
backup as compressed backupset database plus archivelog;
And backups are done in the FRA, I don't specify either name or location, because FRA is used.
If I add the following;
CONFIGURE DEVICE TYPE DISK PARALLELISM 2;
Do I have to change anything else?
Or I have to add %U to the name of the backup file(s)?
Thanks in advance,
Edited by: Diego on 14-nov-2011 9:12

Hi LKBrwn,
Thanks for your answer.
Where should the %U be placed?
I don't use "FORMAT", since I use FRA, RMAN automatically creates a directory the date and puts the backup there.
I.E.
/mnt/backup/EMPRE/backupset/2011_11_14/o1_mf_nnndf_TAG20111114T161916_7d2tfqoj_.bkp is the last backup of a database

What difference do adding 'Plus Archivelogs' make to an open database backup

Hi,
Does adding the 'plus archivelogs' command to RMAN>backup database;
make any difference to the backup when the database is open ?
If the database is open, then RMAN>backup database; is having to include the archivelogs anyway to ensure the backupset pieces will have a consistent SCN and are not fuzzy.
So it seems to my mind that RMAN>backup database;
effectively implicitly adds 'plus archivelogs' anyway
Any clarity greatly appreciated,
Jimbo

Hi Jim,
As far as I understand , its not a compulsion to take archive log backups ( though highly recommended).
You may run into a situation where you just need the DB backup and while recovery you could use the archives already present without taking the rman backup.
For example in case of creating a DR standby database , you can use the rman backup from prod , ship it to the BCP location and thn simply restore using a standby controlfile. Post that start RFS process and it will bring the archives on its own.
regards
KK

Does it necessary to put the "plus archivelog" in incremental backup?

Hi
Because RMAN is using the archivelog to create the incremental backup , does it necessary to put the "plus archivelog" in backup command?

Please cite the documentation that says rman is using the archivelog to create the incremental backup.
Lacking documentation, please post a proof example.In your personal sandbox database, do the following:
1 - delete any existing archivelogs
2 - take a level 0 incremental backup
3 - generate a few archivelogs
4 - delete the generated archivelogs manually, using and os command
5 - take a level 1 incremental backup

Why we need oracle database reboot to put database in archivelog mode?

I know how to enable archivelog mode, but what is the reason that to enable archive log we need database restart. which process forces to do that.

Thanks a lot EdStevens for ur prompt response...I need something that satisfies my managers query.
If the question has originated with the PHB, then my flippant answer is even more relevant ...
PHB's are incapable of understanding the technical details, so I prefer to give them the 'executive summary':
"Because that's the way Oracle is written. We can argue over the technical merits of such a requirement 'till the cows come home. But at the end of the day, we have to shut down the database because the 'alter database archivelog' command will only succeed when the database is in mount (not open) mode. Now, let's work out how we can achieve our objective of putting the database in archivelog mode with minimal and appropriately scheduled down time."
As for the actual down time, it's about as minimal as you can get. How long does it take your database to complete a shutdown once the command is given? How long does it take you to type "startup mount"? How long does it take you to type "alter database archivelog"? to type "alter database open;"? For the database to complete the 'open' process? You could even script it so as to eliminate the keyboard typing time.

Newbie.. is 'backup database plus archivelog...' needed?
