Backup set /piece info
Hi,
Application guy deleted few rows.
So I am asked to do tablespace point time recovery in 11.2.0.3 on aix using old backup(two week before taken).
I would like to check how many backup set and piece name in a L0 backup.Is there any query?
Most of the V$backup_* views contains the following columns
RECID
STAMP
SET_STAMP
SET_COUNT
what is the use of it?
We taking backup in disk on production machine.We going to do TPIR on test machine.So that we moved particular backup set to tape.Os team changed TPO file settings.
While restoring control file,we got the following info.
channel t1: no autobackup in
Even we specified until time clause.
How to check what are the control file's and backup piece aviable in a tape?
Thanks.
Try:
SPOOL LOG TO rman_bkp_ts.log
RUN {
SET UNTIL TIME 'trunc(sysdate)-14';
RESTORE TABLESPACE
ORCL_DATA, ORCL_INDEX, SYSAUX, SYSTEM, UNDOTBS1, USERS
PREVIEW;

Can not restore data files from backup set
I am trying to restore Server A's backup data to Server B (they are all oracle11g) using rman. The restore commands is below:
rman target /;
shutdown immediate;
startup nomount;
restore controlfile from '/usr/local/oracle/backup/20100418/ctl_xxx'
alter database mount;
catalog start with '/usr/local/oracle/backup/20100418/';
restore database;
recover database;
alter database open resetlogs;
For the first time, it works. But when i tried to restore another backup data by the same way:
rman target /;
shutdown immediate;
startup nomount;
restore controlfile from '/usr/local/oracle/backup/20100425/ctl_xxx'
alter database mount;
catalog start with '/usr/local/oracle/backup/20100425/';
restore database;
recover database;
alter database open resetlogs;
The second time, i found that rman restore the old backup data, which means that it restore the data file under '/usr/local/oracle/backup/20100418/' instead of '/usr/local/oracle/backup/20100425/'.
So I run 'list backup of database summary' to see the backup set lists in control file.

there's no backup set 945 at all. that's why i could not restore data file under '/usr/local/oracle/backup/20100425/' at the second time.
So, why two backup list is different ? how can i restore datafile under '/usr/local/oracle/backup/20100425/' ?
My backup script is below:
run{
allocate channel c1 type disk;
backup incremental level 0 as backupset format '$DIR/`date +%Y%m%d`/data_%d_c0_%T_%u' database;
sql 'alter system archive log current';
backup archivelog from time 'sysdate-14' format '$DIR/`date +%Y%m%d`/log_%d_%T_%u';
backup current controlfile format '$DIR/`date +%Y%m%d`/ctl_%d_%T_%I_%u';
release channel c1;
Thanks

My purpose is to use the newest backupset of Server A to update Server B. So if Server A crush, Server B will be useful. Is there any other way to do that ?
retention policy :'configure retention policy to redundancy 4'
And Server A do LV0 backup every 7 day, and do LV1 backup ervery other day.

The DB version is 11.1.0.7.
The "CATALOG START WITH" not only catalog backup set that are not in the RMAN catalog, but also catalog a second copy for files that are already in the catalog.
Files are not a second copy; they are the same file in the same directory.
Having two copies in the catalog, through an error when deleting explicitly the backups.
We have to add the force clause to avoid the error.
RMAN> delete FORCE backup tag 'offsite-1';
The force clause ignores any I/O error.
The delete is part of our scheduled offsite backup script, which returns a false positive error when the force clause is ommited.
I don't want the force clause, in order to be notify if the backup set that are expected to be on disk are no more there, e.g., if someone had deleted files manually at the OS level bypassing rman.
Is there a way to only catalog backup set not in the catalog?
or May be remove the copy #2 entry from the catalog?
Find bellow a test case example:
RMAN> list backup summary TAG 'OFFSITE-1';

I had an external drive failure and had to buy a brand new drive. I was able to restore my info onto a new drive, about 1.5 TB of data. When I go to launch time machine now with the new drive connected and my backup connected, it treats the new drive as if it had different data and wants to create a whole new backup set when it should just append. How do I get around this?
I could just reformat the backup drive and start fresh again but would rather not do that if I can avoid it, just in case there were errors in copying etc.Hi
I should have been more clear, sorry. I work from a laptop. I have 2 external drives - one for my projects which failed but has since been replaced and restored from a backup. My 2nd external drive is the time machine backup drive.
When my project drive crashed, I bought a brand new drive and restored it using my time machine backup drive.
Now the data exists on 2 drives - the time machine backup drive, and the new drive. When I connect the backup drive now, it thinks my new drive has new data, probably since it is a new device/drive, and wants to do a brand new backup, when in fact the data already exists on that very drive. It shouldn't have to back up all 1.5 TB when nothing has changed!
Unless there is a way to tell time machine to simply append to the old backup, I think it will try and do a new backup (1.5 TB). I'm thinking maybe I should just initialize my time machine backup drive now and start over so it is only one backup set of 1.5 TB instead of (2) sets of 1.5 TB! -

Duplicate an old RMAN backup set on Oracle 9.2.0.8 with no catalog

I presume this is happening because the target database has a retention of one day and is unaware of this rman backup that is about 20 days old.
If this is true, is there a way of telling the target database about this old backup set that I now want to duplicate?
From 10g onwards you can catalog a backup piece which might be the fix for this??
I've got round the problem by restoring the database to a different server, but would still like to know if the above is possible.
Can anyone offer any suggestions? thanks.Hi C3PO,
I presume this is happening because the target database has a retention of one day and is unaware of this rman backup that is about 20 days old?Correct the backupset metadata is nolonger available.
From 10g onwards you can catalog a backup piece which might be the fix for this??In 9i you can catalog image copies.
http://download.oracle.com/docs/cd/B10501_01/server.920/a96565/rcmsynta11.htm#1005792
Can anyone offer any suggestions?Another option would be setup a catalog and change the retention policy to 30 days and add extra diskspace.

As i checked the database it will indicate datafile 5 is header corruption.
yesterday i take complete online backup of the database using RMAN but now when i run restore database command it will show as

Hi,
can we define a value for BACKUP SET in RMAN configuration ? For me BACKUP SET is a logic notion then it has no sens to have a value. But in a NETBACKUP template I see :
Size of backup piece (KB): 15000000
Size of backup set (KB): 15000000
At least the both size can not be equal.
What do you think about ?
Many thanks.A backup set can have 1 or more backup pieces so if it has only 1 backup piece (which is your case) then the size of backup set and backup piece will be same and if it has more than 1 backup piece then the size of backup set would be the sum of the size of all the pieces in that set.

Database restore with just one backup set
Hallo experts,
I got a big problem with restoring my XE database. I have a newly created full backup from my XE. While saving the flashback_area I got a hard crash on my system but I saved the last backup set file on a server. Unfortunately I was not able to save other backup sets and I think, there was a special backup of my control files. The restore on another system does not work because of invalid piece.
The data of this database is necessary for my work. Is there anybody out there who can help to restore the data with the existing backup set.
I did not change the entire structure of my original XE database. I only created to schemas with data in. is there any solution to restore the data.
Thanks for any help.
HolgerHi you all,
I think that somebody will be interested in the solution of my problem,so I post it here and in german on my website (www.datacubus.de).
My XEdatabase is successfully restored and I walked through some undocumented and not supported features of ORACLE to win the challenge.
The first fact is, that ORACLE XE has a very static structure if you use it as is. The datafiles are predefined and so a manual restore with a foreign backup piece seems to be possible.
Here is my way:
Create a backup of your controlfile
ALTER DATABASE BACKUP CONTROLFILE TO TRACE;
Shutdown your database
shutdown immediate
Start the database in nomount mode
[holger@MSA04071]$ rman nocatalog target /
RMAN> startup force nomount;
RMAN> quit
Restore the datafiles
I used the following script to restore the datafiles from the backup piece without any check:
declare
devtype varchar2(256);
v_file varchar2(255);
done boolean;
begin
v_file:='/usr/lib/oracle/xe/app/oracle/flash_recovery_area/XE/backupset/o1_mf_nnndf_TAG20070420T234848_32lfb0w9_.bkp';
devtype:= dbms_backup_restore.DeviceAllocate(type => '',ident => 'D1');
dbms_backup_restore.RestoreSetDatafile;
dbms_backup_restore.RestoreDatafileTo(dfnumber => 1,toname=>'/usr/lib/oracle/xe/oradata/XE/system.dbf');
dbms_backup_restore.RestoreDatafileTo(dfnumber => 2,toname=>'/usr/lib/oracle/xe/oradata/XE/undo.dbf');
dbms_backup_restore.RestoreDatafileTo(dfnumber => 3,toname=>'/usr/lib/oracle/xe/oradata/XE/sysaux.dbf');
dbms_backup_restore.RestoreDatafileTo(dfnumber => 4,toname=>'/usr/lib/oracle/xe/oradata/XE/users.dbf');
dbms_backup_restore.RestoreBackupPiece(done => done,handle => v_file,params => null);
dbms_backup_restore.DeviceDeallocate;
end;
Start this script as sysdba. But by carefull. This only works if no entire change of datafiles had taken place!
Reset DBID
Because of the saved DBID within the datafile, the database can't be opened. But there is a little trick for resetting the DBID.
shutdown;
startup mount;
execute dbms_backup_restore.zeroDbid(0);
shutdown normal;
Delete or rename existing Controlfile
Edit trace file
You have to modify your controlfile script as follows:
1. Only use the CREATE CONTROLFILE... block
2. Delete RECOVER DATABASE block
3. Replace REUSE with SET
4. Replace NORESETLOGS with RESETLOGS
Create new control file
Use the CREATE CONTROLFILE block for creation of a new control file.
Open Database
alter database open resetlogs;
Much work but all my data is back and now I will backup the whole flashback_area to avoid further nightmares.
Bye

Backup set in the tape. copied into disk. how to recover using RMAN
I have backup set in the tape. copied into disk. how to recover using RMAN
any link and steps pleaseIt should be something like the following, but really you should read and understand the rman documentation first ...
1. restore the controlfile
sqlplus / as sysdba
startup nomount
exit
rman
connect target /
restore controlfile from '/path to the controlfile backup piece';
exit
sqlplus / as sysdba
alter database mount
exit
2. catalog the backup pieces
rman
connect target /
catalog start with '/path to backup pieces';
3. restore the database
rman
connect target /
restore database
4. recover the database
rman
connect target /
recover database
5. open the database
sqlplus / as sysdba
alter database open resetlogs; -
Recover db without backup sets rman
Hi,
Is there any way to restore the database without backup sets. We have the recent incremental backup, however the backupsets have failed.
Please advise.user12075620 wrote:
RMAN backupsets are defined to have a retention period and moving the backup from disk to tape and then freeing the space on the disk.
where did you get this definition?
RMAN can store backup data in a logical structure called a backup set, which is the smallest unit of an RMAN backup. A backup set contains the data from one or more datafiles, archived redo logs, or control files or server parameter file. Backup sets, which are only created and accessed through RMAN, are the only form in which RMAN can write backups to media managers such as tape drives and tape libraries.
A backup set contains one or more binary files in an RMAN-specific format. This file is known as a backup piece. A backup set can contain multiple datafiles. For example, you can back up ten datafiles into a single backup set consisting of a single backup piece. In this case, RMAN creates one backup piece as output. The backup set contains only this backup piece.

You will need to define your problem in detail if you know what the problem is. what are you trying to achieve? -
Determine set until time from particular backup set
Hi Gurus,
First of all thank you for everybody reading my question.
I am using database control file instead of recovery catalog.
database 10gr2
10.2.0.3
os is suse linux
Is there way (any magic query)
you can determine sec part correctly for set until time looking backup set:
7544 B F A DISK 28-AUG-11 1 1 YES PROD_FULL_BKUP_08.28.2011
ALLOCATE AUXILIARY CHANNEL aux1 DEVICE TYPE DISK;
ALLOCATE AUXILIARY CHANNEL aux2 DEVICE TYPE DISK;
ALLOCATE AUXILIARY CHANNEL aux3 DEVICE TYPE DISK;
#SET UNTIL SEQUENCE 10008 thread 1;
SET UNTIL TIME "TO_DATE('28-Aug-2011 03:40:32', 'dd-mon-YYYY hh24:mi:ss')";
DUPLICATE TARGET DATABASE TO "11demo"
I try hit and try for determining sec part.
is there a proven way.
'28-Aug-2011 03:40:31' worked
'28-Aug-2011 03:40:38' didn't
'28-Aug-2011 03:40:35' didn't.
1)
I look os time stamp set for backup.

2) I add start time(03:00:00) +elapsed time.
channel ORA_DISK_1: backup set complete, elapsed time: 00:40:35
thanksI can get

you can get "SET UNTIL SEQUENCE thread "
correctly,
But How does one find out the exact time the backup was completed?
I simply used the timestamp from the Rman backup as an approximate indicator.

I am restoring the production database to testing server. i have taken the cold backup of my catalog database and refreshed on development server so that i can have information about the production db in RMAN catalog db.
i have copied the backup sets ( level 0 ) of my production db to development server. backup set path is not identical as production. so When i try to recover in dev server i am getting error file not found. ( not able to find the backup piece ) since it is point to production backup set path.
how do i set or update the RMAN database about my testing server backup set path so that during the recovery rman reads from new location on the development.thank you.
I am facing problem while restoring the database.
i trying to restore from level 0 backup which we take daily basis. when i use the below command and while restoring one of the datafile referring the old backup set which is not available. i have valid backup sets taken yesterday. but rman refers the backup sets taken on day before yesterday.
i am using the following command.
rman << EOS
connect catalog rman/rman@PSMTRRCT
set dbid 4151495469;
connect target /;
startup nomount;
run {
allocate channel c1 type disk;
set until time "to_date('9/mar/2011 23:00','dd/mon/yyyy hh24:mi')";
restore controlfile;
restore database;
alter database mount;
exit
EOS
LEVEL 0 backup which i have was taken on 9 mar. but rman refers the 8 march backup set for one particular datafile. since i dont have that backup set. restore fails.
can you please help. -
How to list all available backup sets
Hi,
we are using Oracle 11gR2. there is an requirement to list all avilable backup sets through shell scripts, we have retention period of 15days.
below query gives me list of backup files but it was difficult to know which files was require for "catalog backuppiece"
DBMS_RCVMAN.SETDATABASE(null,null,null,1536975101,null);
SELECT PKEY,FNAME ,BS_COMPLETION_TIME
FROM RMAN.RC_BACKUP_FILES
where
file_type='PIECE'
AND
STATUS = 'AVAILABLE';Backup sets looks below on Disk. all files starting with *"db11g_c-"* are required for catalog backuppiece.
we like to know is there another better way to get this information. we want to list only those files required for cataloging.

Mac mini refuses to recognize existing TM backup set
I just got my mac mini fixed with a new logic board, and I have it connected to a 250GB external FW drive. Time machine was running on a partition on the external drive quite happily since I bought it in November, but since getting it back from the repair, it refuses to recognize that there is an existing backup set on the drive. The hard drive is identical after the repair, machine name is identical, etc.
The machine name is "Wintermute" and there is an existing directory in Backups.backupdb - when I try to run a backup run, it creates a directory "Wintermute 2" and bails out with insufficient disk space (it's trying to do a full backup)
If I right-click Time Machine in the dock and select "Browse Other Time Machine disks" I can select the existing backup and it seems to be OK. However, I can't seem to continue adding to that backup set!
Any suggestions?Here are the contents of my backup volume if it helps at all:
