RMAN restore when system datafile get corrupt

Hi,
I am new to Backup and recovery, Can anybody suggest.
If my system datafile gets corrupt, do I need to restore and recover complete database or just datafile restore will be suffice.
In case the database is running on archive log mode.
Waiting for reply.
Thanks & Regards,
Deepak

How to recover database SYSTEM datafile get corrupt ?

Database is in ARCHIVELOG mode, and the datafile belonging to SYSTEM tablespace gets corrupted. Up to what point can I recover the database ?
A. Until last commit.
B. Until the time you perform recovery.
C. Until the time the datafile got corrupted.
D. You cannot recover the SYSTEM tablespace and you must be re-create the database.
and 1 more doubt :
If redologfiles are not multiplexed and redolog blocks get corrupt in group 2, and archiving stops. All redolog files are filled and database activity is halted.
DBWR has written everything to disk. What command can be used to proceed further ?
A. recover logfile block group 2;
B. alter database drop logfile group 2;
C. alter database clear logfile group 2;
D. alter database recover logfile group 2;
E. alter database clear unarchived lofile group 2;

1. A. Since the DB is in archivelog mode, so you can always restore and recover the whole DB including system tablespace datafile till last SCN generated provided the redo record is available in archive/online logfiles.
2. E. Since only redolog is corrupted so archiver won't proceed and hence a db hang is obvious, So, in order to proceed further you need to clear online (un archived log file) and then db will work as usual. Care should be taken that you must take a full backkup of DB(cold backup wherever feasible) as soon as possible after issuing this command. As now you don't have redo info in archivelog files to recover the db in case of a crash.
Please go through Oracle 10g DB Administrators guide (available on OTN) for more details.

8i: is it possible to restore a SYSTEM-datafile?

Just curious: is it possible to restore a SYSTEM-datafile using rman 8i ?
I was playing with a 8i-database, after a hard reboot the SYSTEM-datafile got corrupted. I want to restore it, but before trying I want to be sure it is possible to restore a SYSTEM-datafile. Any thoughts on this?

first check how many datafiles contains SYSTEM tablespace.
SQL> select ts.name,fl.file#,fl.name
2    from v$tablespace ts,v$datafile fl
3   where ts.ts#=fl.ts#
4     and ts.name='SYSTEM'
5 /
NAME                                FILE# NAME
SYSTEM                                  1 F:\ORACLE\PRODUCT\10.1.0\ORADATA\ORCL\SYSTEM01.DBFthen mount yours database..
RMAN>restore datafile 1
RMAN>recover datafile 1if you have other files exist within SYSTEM tablspace (i.e 1,2,3) then
RMAN>restore datafile 1,2,3
RMAN>recover datafile 1,2,3Khurram

System tablespace gets corrupted.

Hi,
My system tablespace gets corrupted. My Database is not running in archivelog mode and also i dont have any backup. Is there is any solution to recover corrupted blocks in system tablespace;

had the same few weeks ago at one of our customers
SYSTEM tablespace (SYSTEM01.DBF) got corrupted due to power outage/disk error
no archiving, no backup (database for testing purposes, which they update periodically with data from the production database)
tried recovery (as Rafi suggested above), but it didnt work, it said SYSTEM01.DBF needs further recovery, thus open resetlogs wont work
and it was right, resetlogs didnt work :)
so the options:
1. recovery/restore - not possible
2. Oracle has a private tool called Oracle Data Unloader that can get the data from the datafiles - just a test database, doesnt worth the work/time/money
3. open the database with the allowresetlogs_corruption=TRUE hidden parameter, and try a full export
database could be opened with resetlogs by using this parameter
the reward for this action: several ORA-600s per second, instance crashed in 30-60 seconds
at the end we dropped the database and duplicated the production one

System datafile block corruption - no backups and database in NOARCHIVELOG mode

Dear All,
Database version - oracle 11.1 Enterprise
OS - RHELinux 5.8
What are the options of recovering from physical block corruption when there are no backup available to perform block media recovery?
V$DATABASE_BLOCK_CORRUPTION reports two segments corrupted (please see attached image for details).
1 table in system datafile - sys_fba_barrierscn
1 index - (applicaiton index)
What are my options?
I know there is a possibility that the database will not restart after a shutdown due to corruption in system tablespace.
Database is in noarchivelog mode. So online backups are not possible and there aren't any full backups either.
I am thinking of below,
1. Run dbms_repair with fix_block_corruption. - Still database startup might fail?
2. Shutdown the database and take offline full backup with RMAN MAXCorrupt option.
Appreciate your suggestions and advises.
Thanks
Stefan

Thanks Sybrand,
Agree with your first two suggestions .
Also scheduled a expdp job tonight. (Only backup like thing they had was a expdp cron, but until today all the large tables were failing due to small undo_retention).
Yes. Flashback is not used. So hopefully it will not affect the a database restart i guess?
Related to dbms_repair, I was referring to - http://askdba.org/weblog/2010/08/physical-corruption-ora-1578-part-3/.
Where DBMS_REPAIR.FIX_CORRUPT_BLOCKS and DBMS_REPAIR.SKIP_CORRUPT_BLOCKS used.
Which i think will not use any redo.
Thanks
Stefan

System datafile block corrupted

hi there,
i have got a serious problem, my database is in mount state, but when i try to start it up, it gives error datafile block corrupted file 'd:\path\system01.dbf'. these are backup file from last database, afer which os has been formated and reinstalled.
these are files from oracle 9i R1 and i want to install it intom oracle 9i R2.is it ok or i have to install oracle 9i R1 for making database up?
plz help what should i do???
thanks and regards
VD

ya its true,
its not consistent backup.its not RMAN backup.i just have files >DBF,controlfiles and redo log files.
now i am asked to retrieve data from these files.i have rebuild the database, and mounted it.but it is not getting opened.
if i use 'ALTER DATABASE OPEN RESETLOGS' it takes too much time but dosent open.
thats the issue.

Why is Oracle RMAN restoring a datafile to a different diskgroup?

Hello,
When I was trying an RMAN restore of a datafile, I found it is restoring the datafile to a new location. Why is Oracle restoring a datafile to a different diskgroup instead of restoring to the original diskgroup where the datafile was originally present?
1) I have a datafile '+DATA3/slob1/datafile/undotbs2.260.819992871' which is on +DATA3 diskgroup
2) I am taking a backup on to +FRA diskgroup
3) I then offline and delete the datafile 5 using asmcmd to simulate the loss of a datafile
4) I perform restore and recover of datafile 5 from the backup set on +FRA
5) Unfortunately the datafile got restored on to +FRA instead of +DATA3. I realize that the file name can change because it is going to be a new file on ASM but I would assume this will be on the same diskgroup atleast since the control file has it pointing to '+DATA3/slob1/datafile/undotbs2.260.819992871' before restoration.
When I tested on file system, this gets restored on to file system correctly.
Anyone has any idea why the datafile was restored on to +FRA instead of +DATA3?
Below is the screen output of what I did.

ORA-00704: bootstrap process failure and SYSTEM datafile corrupt

We have an Oracle 10g Express database that is getting the following error on startup.
ORA-00704: bootstrap process failure
It is also showing that the SYSTEM datafile is corrupt. And unfortunately the backups are gone. Is there any way to recover from this without a backup? Maybe some hidden undocumented parameter???
We do have some full database exports from a couple weeks ago so it is not a complete loss but would really like a full recover.

Windows XP
We have tried allowresetlogs_corruption and allowread_only_corruption and no luck so far.

Pref files getting corrupted

In the past two weeks I have had computer problems than I have had in years and end up with the solution of removing a bad prefs file.
I have had user prefs, system prefs desktop pictures pref file and several app prefs getting corrupted.
Now I go right to pulling prefs and/or using Onyx to fix the problems.
Anyone else having such a rash of files being corrupted?

Hi Derryl s;
It has been my experience that when files start getting corrupted then the disk drive is generally on it's way out. I would check you disk drive to see if it is having problems.

When I try to restore my iPod i get the iPod is corrupt error...

Ok, i've read through the answers that have been given for the error that comes up when people try to restore their iPod and get this:
"iTunes has detected an iPod that appears to be corrupted. You may need to restore this iPod before it can be used with iTunes. You may also try disconnecting and reconnecting the iPod."
so i get that message when i plug in my iPod still...even after having gone to the Apple Store to try and get it fixed. They fixed the actual iPod but still no success with the computer. And every time I plug in the iPod i get the message about it being corrupt and needing restore.
But whenever i click "Restore" i get a message saying: "There was a problem downloading the iPod software for the iPod "iPod". The requested resource was not found."
someone PLEASE help! I'm getting frustrated beyond belief here, i've tried the chkdsk stuff, and the bit about removing the iPod update software folder, if that's the same solution set, then i forgot what the other part was, but i've tried both of the suggested and nothing's working.
please someone help.

I got this under XP before. I was totally baffled until I realized there was a network drive mapped to the same place XP was trying to mount my iPod. The common symptom is that you'll get this sort of "corrupt" error on one machine but it works ok on a friend's machine. If that's true for you, you can change the network drive mapping to another drive letter (easiest) or mount your iPod and change its drive letter in the disk management control panel (under admin tools).
Hope that helps... this one just about had me pulling my hair out until I recognized the problem.

HT5622 After both (1) changing the password for my Iphone 4S and now (2) loading latest system for it (and restoring when Itunes said I must) it will no longer restore all the apps I bought with the old password. How to get them please?

After both (1) changing the password for my Iphone 4S and now (2) loading system 6.1.3 for it (and restoring when Itunes said I must)
- Itunes it will no longer restore all the apps I bought with the old psasword.
How to get them please?
===========================
Sorry - no - all well, they seem to be all coming back - back just after I put this question.
Mysterious to me but very satisfactory.
Profile doubtless that of an ignoramus.

Ok, so I was able to find one but the one i'm most diappointed is the "free music" app i purchased and it had hundreds of songs that i didn't put on my desk top to save. So just so we're clear, I cannot get that app back again with all my songs if it wasn't in the "purchased" place?
Also,
my husband has a iphone 4 and i've been trying to connect it to our Garmin GPS through bluetooth. Now both devices recognize it but once a call is made or received, nothing goes through the GPS. I've had it working before but it was before a couple of upgrades. It is currently on ios7.2 upgrade. Is that why it won't work?
Thanks

please help me out

I can't do that since I do nothing with Windows.
It sounds like it was hacked to run XP and then makes it not run OS X now.
Only thing I can suggest is to repartition the hard drive to a single HFS+, GUID partition and see if that allows you to install OS X.

HT201250 When getting a replacement Seagate hard drive for my Imac through Apple, will they restore my system to it's current state? Or will I have to do it myself though Time Machine? Will Time machine restore all the programs as well?

Apple has determined that certain Seagate 1TB hard drives used in 21.5-inch and 27-inch iMac systems may fail. These systems were sold between October 2009 and July 2011.
Apple or an Apple Authorized Service Provider (AASP) will replace affected hard drives free of charge.
Will this replacement program restore my system to its current state after the new drive is installed? If not, will I have to have all my original disks to re-install all the programs on my current computer, or will Time Machine restore them as well?

Most of them will tell you to backup your data.
Time Machine is nice, but unless you are interested in archival backup, Carbon Copy Cloner is a lot easier to recover from:
