hot backup control file?

I wonder and wants to know... we can put hot backup control file... If so, then isn't the content of the controlfile changed after backup?

alter database backup controlfile to 'd:\backups\cntrlfilebackup.dbf reuse';
alter database backup controlfile to trace as 'd:\backups\cntrlfile_trace.txt reuse';

switch after the hot backup log file
Hello world
Why should we change log file after the end of the backup command that is to say, after the end of the backup hot?
Why we should take a backup control files to database level, but not through operating system level that is to say, order cp?
Why we should take a backup control files to database level, but not through operating system level that is to say, order cp?

If you're doing a cold backup, this is where you use cp.

But when the database is in place, controlfile is used and it is continuing to change the oracle process. Now the question is how to get the consistent image of the controlfile, here's where you their support at the database level (for example backup controlfile). When you do that level database, a snapshot file is created time and she is saved.

Retrieve by using the backup control file

Hello
I was reading a book called Pro Oracle Database Administration by Darl Kuhn. There, under the theme of "The valuation of the loss of all control files", noted that all data files and control files are restored from a backup, because if we do not restore the data files the RCS in control files would be lower than the data in these scenarios files. Since online redo logs and archived newspapers is applied to the data files to roll forward in a current consistent state and does not roll forward to a control file.
It is then mentioned to use 'recover the database by using the backup control file' then apply the logs (archive and redo if necessary).
However I personally tested this script in a test environment and to bring all the backup control file could issue the same command as above and recover the database.
My question is I know again and archives are applied only to the data files. So how does the control file are synchronized back when we do not restore the backup data files.
Thank you

If we do not restore the data files, the RCS in control files would be lower than the data files. Since online redo logs and archived newspapers is applied to the data files to roll forward in a current consistent state and does not roll forward to a control file.

It would be incorrect you have determined. You can only restore the control files. You can manually create a control file and always do the restore.

My question is I know again and archives are applied only to the data files. So how does the control file are synchronized back when we do not restore the backup data files.

The control file is updated as well.

See you soon,.

Why open DB with RESETLOGS option after either complete or CAMILLE with a backup control file?

Hi all
I'm newbie DBA and totally confused when reading about the recovery.
Why open DB with RESETLOGS option after either complete or CAMILLE with a backup control file?
Using while will happen after we open DB using resetlogs in above mentioned mode of recovery.. .apart from resetting the log sequence 1?
Kind regards
Ritu

Hi Ritu,

Google is a very rich source of information...

I found this article in Hemant which I suppose is very informative for you... Read everything including the comments!

Create the new database of complete hot RMAN, atrchivelog and backup control files
Hi all

I'm trying to create the new database U1234 of P1234 of full hot RMAN, atrchivelog and control P1234 file backup.

Here are my steps

(1) to restore the control file

#! / bin/sh
ORACLE_SID = P1234
export ORACLE_SID
RMAN nocatalog target / < < EOF | Tee restorecontrol.out
startup nomount pfile=/u01/oradba/admin/U1234/scripts/restore/restore071009U1234/initP1234.ora;
the value of DBID 6767676;
run
{
allocate channel d1 type disk;
controfile catering to ' / u02/oradba/U1234/control/P1234_control01.ctl';
Restore controlfile to ' / orarman/restore/P1234/cf_P1234_c-00';
change the editing of the database;
}

(2) database stop then restart the database with the new contraol file using pfile.

(3) restore data files

#! / bin/sh
ORACLE_SID = P1234
export ORACLE_SID
RMAN nocatalog target / < < EOF | Tee restore_dbfiles.out
Run {}

Now, I missed the space during the restoration of data files and want to restore remaining who is 3 and 4 of datafile datafile.

Can you please let me know how I can restore it.

I need to change the names of database after the successful restoration.

Thanks in advance.
Hello..

Do you have free space? If Yes, then you can try: -.

RUN {}
SET NEWNAME for DATAFILE 3 to ' / u05/oradba/U1234/dbfile/U1234_sysaux01.dbf';
RESTORE THE 3 DATA FILE;
DATAFILE 3 SWITCH;

BACKUP CONTROL FILE

Hi all
11.2.0.1
AIX 6.1
I want to save my text control file as in
SQL > alter system backup controlfile to ' / u01/a.txt ';
But the result is not readable
Why is this so the command
SQL > alter system backup controlfile to trace;
The result is readable, but it is very difficult to find
Help, please...
Thank you
zxy

It is certainly, ALTER DATABASE BACKUP CONTROLFILE (to not "changing the system")?

Read the documentation... oh, Yes, you have made a habit of NOT reading the documentation.

The syntax for a text trace file is

BACKUP CONTROLFILE ALTER DATABASE to TRACK AS ' / u01/a.txt ';

RMAN backup control file
HII I am working on oracle 10g 10.2.0.4.0 on solaris 10 have an asm and rac configuration (2 node rac).

I only have a single control file--+DATA_DG1/ftssdb/controlfile/current.270.664476369

I'm back up these files to control with rman

CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT for DEVICE TYPE DISK TO ' / backup/rman_node1/%F';

c 31850833-20100909-00 is one supported by piece of control file.

now, suddenly, a system of administration deleted this file control... How can I recover my database using rman backup?
RMAN > SET 3386862614 DBID
RMAN > RUN {
RESTORE AUTOMATIC BACKUP CONTROLFILE;
}
or
RMAN > SET 3386862614 DBID
RMAN > RUN {
CONTROLFILE AUTOBACKUP FORMAT SET
FOR DEVICE TYPE DISK TO ' / backup/rman_node1/%F';
RESTORE AUTOMATIC BACKUP CONTROLFILE;
}

We can to restore the content of a game without the backup control file?
Hello

I went in earlier today, a situation when someone (it wasn't me this time!):
(1) a to back up a database and its archivelogs, in a compressed backup sets;
(2) pushed the files to another server and
(3) deleted everything on the server source, including ALL control files and control files.

As he tried to recover the control file was missing and asked for help... I worked around the issue by using the snapshot controlfile he had forgotten (lucky me!)

Now I can not remove from my mind the idea that I won't be so lucky the next time... I wonder if there is another way to work around this problem?

Does anyone have an idea how to restore the contents of a backupset when we lack ALL control files and their backups? I tried to save the backup in the controlfile to a different database, but it does not work. I didn't find anyway to recreate a controlfile with a specific dbid without data files (and those who are in the backupset...).

Any other idea? Best regards

Gregory
Hi arkzoyd,
Is the only way to restore data from a backup set files using rman an instance and a controlfile so the answer is no.

Restore the control file considerations

Hello expert,
Assumpition condition is:
All the data files and the redologs are not damaged, but the controlfiles are damaged. We must restore the controlfile autobackup with the following command:
RMAN > STARTUP NOMOUNT;
RMAN > backup RESTORE CONTROLFILE AUTOMATIC;
RMAN > ALTER DATABASE MOUNT;
RMAN > RECOVER DATABASE;
RMAN > ALTER DATABASE OPEN RESETLOGS;
Use of rman RECOVER, DATABASE redo logs to roll changes forward to control files. Can you explain what changes can be included? (Currently I only have one example: we add the new data file once the backup control file.) So we need roll forward the changes to control the file on the new added one.) Other examples?
Thank you and best regards,
Tong Ning

Examine the contents of the controlfile. He has the list of data files, the list of the archivelog files and list of rman backups.

Archivelogs would be saved in the controlfile so that they can be applied.

What about backups? Subsequent backups would certainly no longer be in the controlfile.

so can get us this or can't do?

You seem to have:
(a) old version of data through rman backup files
(b) old version of the control file
(c) Backed archived redo logs
(d) recovery archived logs that have been recently generated
(e) current online redo logs

Therefore, you should be able to bring back the database in the State wherever it was when you made the abandonment.
I don't do enough laps to be able to cite details on the commands to use (and I often find myself using the command line recovery after that file of rman restore, but the steps you need must be)

Take a copy of security of the data current, archived and online redo log files.
Restore the backup control file, data files, and archived recovery logs
Recover the database by using up to cancel backup control file
You have to do 'create datafile' bit as the collection hits the 'missing file' bit
You will need to provide the names of the archived and log files online redo recovery reached their
(although, presumably, you could leave copies of the logs stored in the default location)

Need help with RMAN archive destination error during hot backup
Hello

Oracle 8.0.6, Win 2000 Server.

We take the cold daily backup as our backup strategy. We wanted to implement the backup hot. If one day, I turned on the log mode archive and set the directory to archive in F:\drive to store all archived generated. I took the backup and put the database in noarchive log mode. We continued with offline backup.

After a few days, I wanted to test the hot backup again. I created the directory of the archive in E:\archive\ instead of F:\archive\. When I started the hot backup, all files have been copied except the archives.

The error was:

RMAN-03022: compilation command: sql
RMAN-06162: SQL statement: alter system archive log current
RMAN-03023: executing command: sql

RMAN-03022: compilation command: backup
RMAN-03026: recovery error release of channel resources

RMAN-03013: type command: backup
RMAN-06089: journal archived F:\ARCHIVE\ARCH1_0000327116.ARC not found or at odds with catalog

Complete recovery manager.

RMAN is looking for the destination of the journal archive old i.e. 'f:\archive\ '. I don't have the backup of the old archives of destination. I put the new destination to archive E:\archive\ in the initorcl.ora file, rman is always looking for destination F:\archive\.

Please suggest what to do. How can I remove old information from archive of controlfile and say rman, look in the new archives destination i.e. E:\archive\
Hello
WOW 8.0.6.
Maybe you can run a cross?

change archivelog than any overlap;

Update
Found some docs online for 8.0
http://download.Oracle.com/docs/CD/A58617_01/server.804/a58396/TOC.htm
She does not mention the overlap.
With the change command, you should be able to do the cleaning as well.
If you have moved the archivelogs to the new location, you can use catalog according to the doc.
Kind regards

Control files and backup spfile

Hi all
This is a database of GR 11, 2. There is a running script to keep the full backup.
```
crosscheck archivelog all;
crosscheck backup;
backup database;
backup archivelog all delete input;
delete noprompt obsolete;
```
I checked the controlfile autobackup using - show controlfile autobackup. and it is turned OFF
But when I run - list backup of controlfile; list backup of spfile;
I find that contolfile benefits from the support upwards and also through the above script spfile
Can someone please explain to me how this happens without controlfile autobackup
Thanks in advance

This is a normal behavior on version 11.2 and beyond

No matter if controlfile autobackup turned OFF, RMAN automatically includes the control file and the server settings file in the backups of data file1

(i.e backup database command always include datafile 1 which trigger backup of control and spfile).

How knowledge/check if the RMAN backup was performed using a current control file or database catalog?

Hello
How knowledge/check if the RMAN backup was performed using a current control file or database catalog? I mean RMAN prompt or sqlplus is it possible to know.
Thank you

You're welcome my friend

You can see them using two methods.

as I mentioned above, you can see them connect to the catalog database and you can query using the view that I sent

http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmreprt.htm#BRADV89601

the other method is the list command, you must use the list command after connecting using rman "rman target / catalog cat_user/cat_pass@catdbtns" command

http://docs.Oracle.com/CD/E11882_01/backup.112/e10642/rcmreprt.htm#BRADV8136

Check the value of the control_file_record_keep_time parameter. The default value is 7 days. in the output of the list command, if you can see the old backups to the value, you must be sure that the backup information comes from the catalogue database

SELECT * FROM parameter $ v where name = 'control_file_record_keep_time '.

an example of command list

the list of completed database before backup ' sysdate-10'.
