Snapshot control file
Hi,
I am interested in time of snapshot control file creation.
I have read that snapshot control file is created before the backup take the place. I have tried to take the simple rman>backup database command, but I have seen that snapshot control file is created after all backup process (I have seen the time of creating the snapshot control file).
Can anybody tell me about this? When the snapshot control file is created (before backup, maybe in the memory, because I can't see it on the file system).
Regards,
Dragan
Hi,
I have read this sentence from Oracle Database 10g RMAN Backup & Recovery:
RMAN needs to get a consistent view of the control file when it sets out to make backup of every datafile. It only needs to know the most recent checkpoint information and file schematic information at the time backup begins. After the backup starts, RMAN needs this information to stay consistent for duration of the backup operation; in other words, it needs a read consistent view of the control file. With the constant updates from the database, this is nearly impossible - unless RMAN were to lock the control file for the duration of the backup. But that would mean the database could not advance checkpoint or switch logs or produce new archive logs. Impossible.
To get around this, RMAN uses the snapshot control file, an exact copy of your control file that is only used by RMAN during backup and resync operations. At the beginning of these operations, RMAN refreshes the snapshot control file from the actual control file, thus putting a momentary lock on the control file. Then, RMAN switches to the snapshot and uses it for the duration of the backup; in this way, it has read consistency without holding up database activity.
I must ask you if I am using control file only (not recovery catalog) what is happening when I am executing simple RMAN command> backup database;
You have said that I don't create snapshot of control file at that moment, only at the end of the backup process (I have also try it in my environment and snapshot is created at the end of the backup process).
How RMAN knows what to backup (which files), he takes this information from original control file (not from snapshot) I suppose.
What is happening when he finished backup of some backup set, he writes that information again in original control file I suppose.
And at the end of all process why he takes snapshot of control file (to backup control file from it, not from original control file, because control file is always changing, need to lock it). In that snapshot control file (and in the its backup) we will have the pointers on files that are made after the backup process started (is this true).
Thanks,

ORA-00230: operation disallowed: snapshot control file enqueue unavailable
Hi,
on 10g R2, on Win 2003
my rman backup failed (just at the end) with :
release channel 000
ORA-00230: operation disallowed: snapshot control file enqueue unavailable1-should I rerun the back up task ?
2-how to verify if this backup is correct/good ?
PS : I use nocatalog (controlfile for repository)
Thank you.1-should I rerun the back up task ?appear its failed during controlfile backup if database backup log fine than just take controlfile backup.
2-how to verify if this backup is correct/good ?in 10g ,we can see status in v$rman_status view,it also show any other running job as well.
select * from (select SID ,recid ,STATUS,operation,MBYTES_PROCESSED/1024 "GB",START_TIME,END_TIME from v$rman_status order by start_time desc) where rownum <11 -
Restoring Control file from snapshot
Hi,
As in RMAN the following configuration will create snapshot of control file.
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'product/10.2.0/dbs/snapcf_PROD.f'; # default
My question is how to restore control file from this snapshot to another location.
Regards
KrishnaCopy RMAN backup files including archive log backup files to the target server
Copy the SNAPSHOT CONTROL FILE or backed up control file from source server to target server.
Source Server:
RMAN> connect target /;
connected to target database: HRDMO (DBID=209403493034)
RMAN> show SNAPSHOT CONTROLFILE NAME;
using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/opt/oracle/10g/dbs/snapcf_HRDMO.f'; # default
Target Server:
Export ORACLE_SID=HRDMO
RMAN
RMAN>startup nomount;
RMAN> set DBID=209403493034;
executing command: SET DBID
RMAN> restore controlfile from '/opt/oracle/standby/dbs/snapcf_crmprod.f'; # The location where you have it in target srvr.
RMAN>alter database mount;
RMAN> run

RMAN>alter database open resetlogs;
You have the copy of instance in the target server.

ORA-00245: control file backup failed; target is likely on a local file sys
Hello,
our RAC (Linux, 11.2.0.3.0) is rather new and we are still on gaining experiences with that system...
When starting the backup with RMAN we are getting the following error:
Starting Control File and SPFILE Autobackup at 04-JUL-12
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of Control File and SPFILE Autobackup command on ORA_DISK_1 channel at 07/04/2012 16:41:48
ORA-00245: control file backup failed; target is likely on a local file system
The reason for the error is clear ORA-00245 - in a RAC environment the location of the Snapshot Controlfile must be on a shared location.
When executing the RMAN command "show all" on each node, we are getting
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2.0.3/db/dbs/snapcf_PROD021.f'; # default
for node #1
and
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2.0.3/db/dbs/snapcf_PROD022.f'; # default
for node #2
When using a shared location for the Snapshot Controlfile do we still need to setup 2 different names for that file?
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/<shared location>/snapcf_PROD021.f'; # default
for node #1 and
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/<shared location>/snapcf_PROD022.f'; # default
for node #2
Or should we configure just one Snapshot Controlfile?
The RMAN setup for "CONFIGURE SNAPSHOT CONTROLFILE NAME TO..." must be changed on both nodes - correct?
Hopefully my question is clear enough - any help will be appreciated.

Edited by: VivaLaVida on 05.07.2012 11:41No, it must be configured on a shared storage:Not really required, i've RAC setup and snapshot is configured on local storage.
Configuring the RMAN Snapshot Control File Location
The snapshot control file is a copy of a database control file created in an operating system-specific location by Recovery Manager. RMAN creates the snapshot control file so that it has a consistent version of a control file to use when either resynchronizing the recovery catalog or backing up the control file. In Oracle RAC, the snapshot control file is only needed on the nodes on which RMAN performs backups; the snapshot control file does not need to be globally available to all instances in an Oracle RAC environment.
See below from doc.

You need to :
CONFIGURE SNAPSHOT CONTROLFILE NAME TO <shared_location_file>;Hemant K Chitale -
Need of configure snapshot ctl file ???
why i need to Configure snapshot controlfile ??
this is a temporary file used by rman for read consistenacy.
<As Per oracle DOC>
RMAN needs to resynchronize from a read-consistent version of the control file, it creates a temporary snapshot control file.

Now, if it not possible to get above backup piece back, then how to proceed with restore with backup piece DF_L0_HFM11PRD_10112012_l8npv5b6_13992_1 as it also has control file backup and available on disk, not obsolete. I can understand the reason for marking CF* file as obsolete because of redundency 1. But how to proceed with restore with available backup ?Hello;
I would change my configure for one :
RMAN>CONFIGURE CONTROLFILE AUTOBACKUP ON;Would use this to check :
list backup of controlfile completed before <date>And would catalog everything again just to be sure before starting the restore.
You may have to catalog use the control file piece to avoid the error.
RMAN> catalog backuppiece ...Another idea is to test the restore using something like this :
RMAN> run {
set until time "to_date('2012 NOV 17 07:00','YYYY MON DD HH24:MI')";
restore controlfile preview;
}Best Regards

Job output is no longer available in the database control file
Im running my rman backup with Oracle Enterprise manager grid control 10.2.0.1.
In nocatalog mode.
When I look for the job output in the "View Backup Report" section, it says
Job output is no longer available in the database control file.
Here is my rman setup:
RMAN> show all;
using target database control file instead of recovery catalog
RMAN configuration parameters are:

anyone knows why i cannot see my rman job output?show parameter control_file_record_keep_time;
NAME TYPE VALUE
control_file_record_keep_time integer 7
The backup is usually the last one. And it's the day before.
If i go to the JOB tab in oem, then click on the job detail, i can see the detail of my rman backup. But i cannot see the backup detail in the View Backup Report section off the database. It says the error message : Job output is no longer available in the database control file -

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.

RECREATE DATABASE Using CONTROL File After SUSPEND Database
Hello All,
Does someone can tell me if he does achieve recreating a database using "Backup Control File" after putting database in "suspend" mode?
The procedure looks like this :
1 - Alter DATABASE Suspend
2 - A Snapshot of the filesystem where the oracle datafile are located
3 - Copy of those files to another file systeme
4 - Startup setting a new database name
Does someone as do it successfully ?
Thanks for your answerCarlos,
I tried to do it without putting the tablespaces in backup mode and it didn't work for me. At that time adding the backup mode wasn't a big deal for me, so I didn't investigate the problem thoroughly.
Logically thinking you sould be able to do:
1. suspend database
the SCNs recored in datafiles headers could be incosistent at this point
2. make a snapshot
3. mount the backup database
4. run recover until cancel using backup controlfile - I don't think you can avoid this step in case if you have inconsistent SCNs in the datafiles headers - you'll need to synchronize them
5. open resetlogs.
the suspend database should eliminate the possibility of inconsistent data within a block during the backup.
Just out of curiosity - why don't you want to put the tablespace in the backup mode?

Starting backup at 28-JUN-09
using channel ORA_DISK_1
It is in this situation since 4 Hrs.
I had set all the permissions as mentioned in the SAP Note : 113747. Backup was happening as normal till 25th June thru DB13.
My observation is, I had alter the oracle parameter as per the quiry results. ( i.e added the events .. I had executed the script attached in the S.Note : 1171650. ST04 --> Performance --> Additional Function --> SQL Command Editor )
O/S : AIX 5.3,
DB : Oracle 10.2.0.2.0
ECC 6.0
Backup in all other servers are happening without any problem..
I appreciate your expert suggestions.
Thanks!
Sundaresh SuryanarayanHi Surendara Jain,
Still this problem persisting.. I have tried all.. I checked all the relevent S-Notes. I updated the brtools version also..
Even if I execute BRBACKUP it starts.. It creates the folder. But, the folder will be empty.. Pls. see the *.and file below..

This control file is in the Oracle Windows default dir but I am not using it and did not create it.

Any idea why this is happening?That is a SNAPSHOT CONTROLFILE, created by RMAN as a copy of the current controlfile.
Wonder how and why the copy is corrupted ? Check the timestamp of the file to see when it was created. A RESYNC will always create a fresh Snapshot Controlfile.

In case of Control File Failure, Create Control File cmd how get scn?
The following lines i picked from the
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:5033895918209
======================================================
1. We can use the 'alter database rename ' at mount stage to rename any datafile. Or is it not possible to rename the system datafile like this? Why?
2. What happens to the SCN information in the controlfile when a controlfile is recreated? How will the database sync the SCN with that of the datafiles?
If I issue a 'backup controlfile to <file>' at 8 am and then restore that controlfile binary backup at 10 am and try to open the database, it will give me a control file old error. I understand that it is because the SCN is not in sync. But if I issue a 'backup controlfile to trace' at 8 am and use that script to recreate a new controlfile at 10 am, why doesn't I get the error? Where does it get the SCN information then?
So what is the use of taking a binary copy of the controlfile. Looks like having a 'backup controlfile to trace' script is better than a binary backup. Do you agree? Why/whynot?
Followup August 16, 2002 - 2pm US/Eastern:
1) you could but I just always did it with the create controlfile statement.
When moving system -- I do it that way
When moving ANY OTHER tablespace -- i just offline it, move the files, rename the files online it.
2) it just happens.
The control file you create will read the files to figure out what is up.
I agree, I've never used a binary controlfile backup myself.
=========================================================
My Question- In the Point2 above "Where does it get the SCN information and how control file do SCN Sync with data files?
"1. The CREATE CONTROLFILE reads SCNs from the DataFiles. If the
database was last shutdown, all the datafiles are "non-fuzzy" and have the same
SCN (as of the shutdown checkpoint), If the database or some of the files are from
are hot backup, you cannot open the database because the SCN of some files is
older (lower) than others -- that is why a RECOVER (DATABASE or DATAFILE) is
required.
See http://web.singnet.com.sg/~hkchital/Incomplete_Recovery_with_BackupControlfile.doc
2. I'm not sure I agree with Tom Kyte's response
"I agree, I've never used a binary controlfile backup myself. "
to the question
"So what is the use of taking a binary copy of the controlfile. Looks like having a 'backup controlfile to trace' script is better than a binary backup. Do you agree? Why/whynot?"
If you have lost your database (storage/filesystem failure) and all your datafiles are lost,
you cannot simply do a CREATE CONTROLFILE from a Trace -- because the
CREATE CONTROLFILE has to read and verify all the datafiles specified in the
CREATE statement. If you have an RMAN Repository, you can use that to restore
your database files but otherwise, the RMAN information about backups and backupsets
are in the binary controlfile.
That is why it is important to take binary controlfile backups either manually or
using RMAN or using CONFIGURE CONTROLFILE AUTOBACKUP ON.
