Autobackup

Hi ,
In my 10.1.0.2.0 DB I have scheduled RMAN backup and configured controlfile autoback ON. As I know when this backup process will run it will make an autobackup of controlfile and spfile in FRA( as I mentioned default). But what I see sometime in a single day the autobackups are 2 or 4 in numbers.
Can you please tell me how this autobackups are being generated more than once ? Other than RMAN backup process who can generate autobackup?
Regards.

Thank you Sir,
I have got it, it was due to the structural change in the DB.
Regards.

Do I need to pass in the source host name when configuring the channel? So instead of
send 'NB_ORA_SERV=pobackup01, NB_ORA_POLICY=jdeoracle, NB_ORA_SCHED=hotfull';
i would need,
send 'NB_ORA_SERV=pobackup01, NB_ORA_CLIENT=newhost, NB_ORA_POLICY=jdeoracle, NB_ORA_SCHED=hotfull';
??

Ok, problem solved. Here's the complete process for recovering a non-archivelog mode data base to a new host from a cold backup from veritas 6.5 tape library.
I used the "until time 'SYSDATE-5'" option because the cold backup was taken 5 days ago, and while rman will look back up to 7 days, it was taking forever to search for the autobackup. This let it start searching on the day the backup was made. The original problem I was having was due to the fact that the backup was taken from one host and the restore was going to another and I wasn't sending the old host name as the NB_ORA_CLIENT parameter. So it was searching backups from the new host for the data.

Why does the RMAN Backup struck at Controlfile , SPFile autobackup?

Hello;
I believe the issue is caused by your media management software. You should contact your media management vendor.
Try the same operation to disk and I bet it works.

I have 2 MacBooks at home that back-up to a Time Capsule. I'd like to buy an external Thunderbolt drive at work to have as an additional back-up. Will Time-Machine support autobackups to 2 different devices?

I have 2 MacBooks (1 Air and 1 Pro) at home that back-up to a Time Capsule. I'd like to buy an external Thunderbolt drive at work to have as an additional back-up (so that were there to be a fire/water damage/etc) I would not lose both the computer and the backup.
Will Time-Machine support autobackups to 2 different devices?
I'd like for it to be able to backup to an external Thunderbolt drive attached to my thunderbolt display when I dock the MacBook Air to it.
Does anyone know if this will occur automatically, or if I will have to manually select backup disk?
thanks

Yes, with Mountain Lion you can do this, but I will leave the explanation to Apple Support Communities contributor Pondini:

can anyone tell me how to trace the error? there is no mention anything in the content.

There is no indication of any error in the part of the trace that you posted. If this alert log trace entry and associated trace file is created every time the rman backup is ran and there is no error number or formatted dump information in the trace file then the trace may just be a left-over from development debugging. Oracle development has been known to forget to turn off trace and debug information before releasing the code to production in the past. This may be another example.
Otherwise you need to post the error messages in the trace.

What's the difference between "controlfile autobackup" and "snapshot contro

Hi All,
What's the difference between "controlfile autobackup" and "snapshot controlfile" in RMAN configure ? Both are controlfile backups, what the difference between the controlfiles they backup ? Why there are two of these options ?
thanks

RMAN creates a control file snapshot to perform catalog resync operations. Control file autobackup will automatically create a backup of the control file whenever there are database structure changes.

No controlfile autobackups in 10gR2. Bug?

I'm using 10.2.0.4 enterprise edition and have no flash recovery area set up. In rman I have controlfile autobackup = on but I am not getting any controlfile backups when I make structural changes to the database.
Here's a snipped version of my RMAN config.
<tt>
RMAN> show all;
RMAN configuration parameters are:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
</tt>
Now I go to sqlplus to show that there is no FRA, and create a tablespace.
<tt>
SQL> show parameter recov
NAME TYPE VALUE
db_recovery_file_dest string
db_recovery_file_dest_size big integer 0
SQL> create tablespace dummy datafile '/export/home/oracle/dummy01.dbf' size 2m;
Tablespace created.
</tt>
Now I check the dbs directory for backup controlfiles. None are created
<tt>
$ pwd
/oracle2/app/oracle/product/10.2.0.4/dbs
$ ls -l c-*
c-*: No such file or directory
So what am I doing wrong? This works fine in 10.1 and 9.2. Did something change in 10.2? Do I have to create a flash recovery area for controlfile autobackups to work in 10.2?

Did you try to test it ?

Restore controlfile from tape backup without autobackup setting on

I am testing a scenraio of restoring control file if we loose all control files.
My RMAN settings for CONTROLFILE AUTOBACKUP is OFF. But, I have taken a backup of controlfile using 'BACKUP CURRENT CONTROL FILE' .
When I tried to restore control file. I am receiving following error:
RMAN> run {
2> allocate channel c101 type sbt_tape;
3> restore controlfile ;
4> }

RMAN-06563: control file or SPFILE must be restored using FROM AUTOBACKUP
My question is, How can I restore control file from tape backup without CONTROLFILE AUTOBACKUP setting ON.
It sounds like, There is no way we can restore control file from tape backup if you've not set the CONTROLFILE AUTOBACKUP is ON.
Please advice

When all controlfiles are lost and a recovery catalog is NOT used, RMAN has no information , where to find the controlfile backup. It's not enough to specify the channel, such a channel could hold many different backups from many different databases. You have tell , which database and which backupset. Modify your run block:
SET DBID <DBID of the database,for which you want to restore the controlfile>;
RESTORE CONTROLFILE FROM <name_of_backupiece_which_contains_the_controlfile backup>';

Restore CTL file from AUTOBACKUP earlier than my backupset?

Hi ALl,
I'm new to RMAN and inheriting a backup procedure and have a question about an output when trying to do a restore.
Oracle 11G 11.2.0.3 on WIndows 2008 R2
This is the RMAN backup commands:
CROSSCHECK ARCHIVELOG ALL;
CROSSCHECK BACKUPSET;
CROSSCHECK BACKUP;
CROSSCHECK COPY;
DELETE NOPROMPT EXPIRED ARCHIVELOG ALL;
DELETE NOPROMPT EXPIRED BACKUPSET;
DELETE NOPROMPT OBSOLETE;
BACKUP CURRENT CONTROLFILE;
BACKUP AS COMPRESSED BACKUPSET DATABASE PLUS ARCHIVELOG DELETE INPUT;
EXIT;THen i copy the ORAFRA to another server and run the following commands (after shutdown)
rman TARGET / NOCATALOG
SET DBID=XXXXX;
STARTUP NOMOUNT;
RESTORE CONTROLFILE FROM AUTOBACKUP;
ALTER DATABASE MOUNT;The quirky thing is, the output of the last one says the control file was restored, say on May 26th.
In my backupsets, i have daily backups all the way until today, June 3rd.
In the ORAFRA, i dont have AUTOBACKUPS past May 26th though my backup job has been running fine since then.
Then i run this:
RUN
RESTORE DATABASE;
RECOVER DATABASE NOREDO;
}Thinking that i want to restore to the last full daily backup which is last night at 7pm (June 2nd).
With the control file being restored to May 26th, will this be possible or am i missing something?
Thanks in advance.

Hi mseberg,
Yes i wouldhave thought that the AUTOBACKUP folder would have folders for each of the past days, but it only has it until May 26 - so it's missing almost a week of folders.
The restore/recovery finished but when i tried to open the database, it threw an error:
Finished restore at 03-JUN-13
Starting recover at 03-JUN-13

Recovering controlfile from autobackup

Hi to everyone,
I am practisisng RMAN backup and recovery in oracle 10g xe . My database is in noarchivelog mode. And I want to recover from loss of controlfile. I am performing following steps:
RMAN> STARTUP
$ mv ~/oradata/XE/control.dbf cc.bak
RMAN>SHUTDOWN ABORT
RMAN>STARTUP NOMOUNT
RMAN> RESTORE CONTROLFILE FROM AUTOBACKUP;
RMAN> ALTER DATABASE MOUNT;
RMAN> RESTORE DATABASE;
RMAN>RECOVER DATABASE NOREDO;
RMAN>ALTER DATABASE open RESETLOGS;
and database recovered successfully. But I read oracle docs that says before restoring controlfile autobackup, we need to set dbid first. How can above steps that I perform also a success.

ORA-19507 when restoring pfile from autobackup

Hey,
We're testing our disaster recovery process and recently installed netbackup 5.1 on a AIX 5.3 server. Our database is 10.2.0.4.
We've imported the tapes, seemingly successfully. Now we are trying to restore the pfile from an autobackup of the spfile. RMAN finds the appropriate file in the netbackup catalog, but can't read it, it seems. The tape device is a standalone drive. I've tried loading the tape at various points in the process, to no avail. Any ideas? Here's the stack:
RMAN> run

Recover spfile using autobackup

Is there a way to make this command:
restore spfile to pfile '/tmp/pfile' from autobackup;
Use only disk. When I run the command it searches all
the disk and then the tape.

did you try
run { allocate channel c1 type disk; restore spfile to pfile '/tmp/xxx' from autobackup; release channel c1; }

Why can't I restore the controlfile from autobackup?

Running 10GR2
Something that I have always had a problem with is the restore controlfile from autobackup command. RMAN is configured to run autobackyps of the controlfiles.
I have setup a restore test and moved the backups over to the test machine. I have restored the spfile and modified the necessary init parameters. When I startup nomount and try to restore the controlfile from autobackup RMAN says it cannot find an autobackup controlfile.
I have always gotten around this by explicitly naming the controlfile to restore but am wondering what is possibly incorrect in my config such that RMAN doesn't know where to find the controlfile autbackups.
Thanks

Do you have such a configuration?
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
You must not specify any other format,only '%F'.
FRA structure should like <db_recovery_file_dest>/<SID>/AUTOBACKUP/<date>/<controlfile_backup>. Only when both is true, RMAN will find the autobackup, otherwise it searches in the OS dependent default location.

No autobackup of control file for rman

This is what I used for a backup of database. I do not have controlfile autobackup set, I back it up using rman commands. Backup is made to a third party media manager.
I tried to restore and it cannot startup mount the database, it can only nomount the database. I am assumming this is because it cannot find the control file.
Is it possible to recover the controlfile if autobackup not on ? I did make a backup current controlfile with the rman script below .. Is it possible to get back the database at all ..

Default device type configuration of controlfile autobackup ?

1. configure controlfile autobackup format for device type disk to 'E:\oracle\oradata\oid\bk\%F';
2. backup current controlfile;
rman first use default device type ORA_DISK_1 and backup the file at "E:\ORACLE\ORA92\DATABASE\0AEU5OQL_1_1" (windows 2000)
then backup file at "E:\ORACLE\ORADATA\OID\BK\C-804947643-20030807-00"
when i backup database , rman can backup the controlfile at "E:\ORACLE\ORADATA\OID\BK\"
when i backup controlfile manully , why rman first backup it at the default device ??
thanks:)

One more cogent point for auto backup on will always get automized backup whenever you made any physical structural change in yours database ,whenver you make any physical structural changes in yours database it goes to be highlight in control file,auto backup on will take this new highlighted control file backup at the spot,needn't to take control file backup after any structural changes It will be backed up itself in yours FRA (Flash recovery area).

How to restoring controlfile when autobackup was not enabled from TAPE?

Database was dropped an year back and we need to restore the database
1)controlfile autobackup was not enabled
2)backups are in tape
3)no catalog db used
4)DBID is known.
we can request to load tapes that are holding backups from 1 week prior of db drop date
we can not use "restore controlfile from autobackup" as autobackup was not enabled. So how can we restore the controlfile?

1)catalog those backupsets
2)check the backup summary for controlfiles & datafiles, SPFILE(optional)
3) if exist then you can restore using DBID or catalog start with commands.
Thanks
