Datafile was corrupted

After accident and wrong operating,
a datafile in oracle database was corrupted and replaced
with older file, so this datafile's checkpoint_chang# number
was lower than other datafiles. Recover fail because database
run in NOARCHIVELOG mode, and this datafile' checkpoint_change#
is out of range of online redo log. There is NO backup file of
other datafiles, so other datafiles could not be restored with
older files.
Is there any way that can simply change a datafile's
checkpoint_change# number,make it same as other datafile,
and take it online,then open the database?
(Data in this datafile has no reference relation
with data in other datafile, so I think taking it
online will not break reference consistency)
null

As I believe as per my knowledge that checkpoint# cannot be amended by the user , this activity taken care of by oracle itself.
Since your database in NoArchivelog mode so recovery also not possible. I have one option (basically R & D) that if your database activity is not much high and your redolog files are large enough i.e. they have not overwriiten till now after the problem then bring your database open using archivelog mode and then apply the recovery using these log files. Although Task is critical , so make your backups completely before moving this.
Otherwise if you are ready to loose the data of datafile which is old one then you can create new datafile with the same name at the same location and startup your database.
Better if you do these two options in Temporary database then finally applied to production.
Kindly do let me know at my id if things work or U have some other option.

Sysaux Datafile was Corrupted

hi , i m new to this forums...
one of my Learning Instance sysaux Datafile was corrupted...
how to recover it?
is Point in time Recovery is Possible??

Hi all,
If are there no backup for sysaux?
there is a corrupted block on datafile of sysaux.
Because this, I cannot export, drop, anything.
so, I´ve tried to use:
run
   set newname for datafile 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\DEVDB\SYSAUX01.DBF'
   to 'C:\ORACLE\PRODUCT\10.2.0\ORADATA\DEVDB\DATA\SYSAUX01.DBF';
   restore (tablespace sysaux);
   switch datafile 3;
   recover tablespace sysaux;
}But with this I got the error:
RMAN-06054: media recovery requesting unknown log: thread 1 seq 2874 lowscn 47185106
So I´ve tried:
BLOCKRECOVER DATAFILE 3 BLOCK 50139;But with this I got the error:
RMAN-03002: failure of blockrecover command at 04/29/2008 16:04:30
RMAN-06026: some targets not found - aborting restore
RMAN-06023: no backup or copy of datafile 3 found to restore
Is there any other way to restore and recover this?
I would like at least to export, but I got error too. :-(
thanks!!!!
Obs: I have backup for all database files, but when I did the backups,
because this datafile is corrupted, I take the tablespace offline.

Data recovery from Datafiles of corrupted database ?

Hi all
Actullay one of my databse(Oracle 9i) is corrupted and i dnt have .dmp files . so i inatlled the new databse.
before that i copied the oradata folder from prevous database( Is not running right now)
is there any way to restore the prevoius data from the files that i have in oradata folder to the new instance.
thanks & regards
Vivek

Has the database - even when it was corrupted - been shutdown cleanly ?
If yes, and only if you have all the files, it should be startable.
If any of the datafiles is corrupted and it prevents database startup, you can always try following:
startup mount
alter database datafile <filename> offline drop;
If the database is/was in archivelog mode you can omit the "drop" and only put it offline.
As soon as all corrupted datafiles are put offline, including all not corrupted from the same tablespace, the database should be able to open.
Keep in mind that this is only true for datafiles not belonging to SYSTEM/SYSAUX or other Instance dependant tablespaces;
I don't think you can restore data from corrupted datafiles, unless you're able to recover them

You should maintain your database backup a little more carefully. Saying that "we don't have any and the one we had , got deleted" just shows that the backup/recovery is not taken seriously.
About the corruption, how did the file got corrupted?Is it a file corruption or a block corruption?If its a full file, probably you can go ahead and can recreate the corrupted file with alter database create datafile
http://download-west.oracle.com/docs/cd/A87860_01/doc/server.817/a76993/performi.htm#16272
The only issue is,you need archivelogs since the time the original datafile was created. If this would be more older than the 3 days of archive logs you have, it would be an issue.
To sum up, if you don't have ANY backup, you are mostly out of luck here. That's more true as you are using a very much older and unsupported version of Oracle which is officially not part of main stream, supported releases.

A Dell Technician told me my Firefox 3.6.17 was corrupted and uninstalled it and Installed 4.0. Now I lost all my sub-folder Bookmarks and some Folder Bookmarks. How to I retreive them?

I had about 100 Bookmark Folders and 500 to 600 Bookmark sub-folders inside the Bookmark Folders on Firefox 3.6.17. When I signed off my Windows XP system on Thursday the Firefox home Page was fine. When I logged on to the Firefox Homepage the next day the page changed and I was unable to change it back, the "add Apps" had no effect and I could not customize the page. My home page is google com ig dell using Mozilla Firefox as my Browser so I called Dell to get help. The Dell technician played with it for about 1 1/2 hours and then decided Firefox was corrupted and he would have to load a new copy. He uninstalled the old 3.6.17 and installed 4.0. I specifically told him I had lots of Bookmarks and could not lose them. He assured me it would be No Problem. When I checked after he finished, I had lost all my bookmarks. The Dell Technician could not retrieve the Bookmarks and had to go to a Dell Datasafe Backup that I did. He could only retrieve a small portion of my Bookmarks. It will take me weeks to build these Bookmarks again. I can't believe these are all gone from my hard drive. Is there anything I can do to retrieve them and how can I prevent this in the future.

I, too had my book marks disappear when I upgraded to FF 4.0
I am now back and enjoying FF 3.6.17 (my original) yet I am still
without my book marks and am floundering trying to recoup.
Any help appreciated. If unable to see my book marks in the near
future I will definitely jump ship. It's too bad that FF people have
created this problem. I am mystified and disgusted with their actions.

My iphone 3gs stopped working and i tried to restore it on itunes but it said a file was corrupt any suggestions?

What file did it say was corrupt? What error number? What is showing on your phone right now? What version of iTunes? What kind of computer?

I am syncing my ipod but it comes up with a error saying itunes could not backup the ipod because the backup was corrupt or not compatible with the ipod, what do i do?

As I said the iTunes program on the computer. You open iTunes on the computer and go to the View menue in the upper rightand then click on preferences. Go to Devices and delete the backup.

I attempted to download a podcast but it was corrupt and only a fraction downloaded. It won't download and I can't delete. How do I get it off my itouch?

I attempted to download a podcast but it was corrupt. Only a fraction downloaded and I can't download nor delete. Any ideas as to how to delete?

If a Podcast has only partially downloaded, then you need to delete that partial download before iTunes will "allow you" to begin a fresh download of that same file.
Have a look in your iTunes Media folder for the Download folder. On my Windows 7 for instance, it's Music/iTunes/iTunes Music/Downloads. In that folder, there should be a sub-folder with the name of that podcast which has the partial download in it. Delete the named podcast folder, but not the Download folder.
You should then be able to start a fresh download (if you still want it!).

My itunes wont auto sync my iphone 4 after i connect it to itunes. But it can auto sync when i connect it to my old laptop. what's the problem that it can't auto sync and when i did a backup in my new laptop, it was corrupted the next day.

But it can auto sync when i connect it to my old laptop. what's the problem that it can't auto sync and when i did a backup in my new laptop, it was corrupted the next day and i was forced to use back a backup which i did in my old laptop 4 months ago. do i have to reinstall the itunes? will my backups be corrupted after i sync again? pls guide.
P.S/ its the latest version of the itunes whenever i did the backups.

iPod touches or any iDevices from Apple sync only to one computer. If you sync to a different computer, all your music will be replace with the music from the new computer's iTunes. If the music were purchased from iTunes, you can re-download them again otherwise the music on iPod touch will be deleted. Do you have iTunes backup?

Unable to sync or backup my iPad2 with the new iTunes. I keep getting the error ""iTunes could not back up the iPad because the backup was corrupt or not compatible with the iPad.". I've deleted all the old backups but still get this.

I'm totally frustrated by iTunes and don't know how to solve my problem. Like a lot of people on here I'm not able to sync or back up my iPad2 with my iTunes (version 10.4.1.10). I'm running Win 7 Ultimate 64 bit. My iTunes worked just fine until the 10.4.xx updates came out and since June I've not been able to back up or sync the iPad2.
When I connect and try to sync I get the error message, “iTunes could not back up the iPad because the backup was corrupt or not compatible with the iPad.”
I've deleted all the old backups so there are none on my system. I've deleted iTunes and re-installed the 64bit version several times but it has not made any difference. I've read and followed several suggestions on these boards about how to remove and reinstall everything but none have worked yet. I'm stumped here.

I had the exact same thing with my shuffle - same error message saying that it was corrupt so I restored it (wiping everything in the process) and the same message came up as soon as it reloaded. Thank god I didn't try it with my iPod or iPhone first. So many issues with this new version of iTunes!!!!!!!!

ITunes could not restore the iPhone "___'s iPhone" because the backup was corrupt or not compatible

Ok so bear with me here, it is somewhat of a long story.
I had been using an iPhone 4 for a while, with an old iTunes account that has all my stuff from over the years on it, on my computer. A week ago, I dropped by iPhone 4 in the sink and it got covered with water, despite quickly pulling it out, putting it in rice under a lamp, the phone was shot, and I was without a phone. My Dad, who is on the same AT&T plan with me, was using an iPhone 3. He was available for an upgrade, so he got a new iPhone, and gave me the iPhone 3. Now i'm not an apple master or anything but I have a good idea of what I am doing, normally, I backup my phone to my computer every few months. Basically everytime I plug it in to my computer which isn't very often because I just charge it with the wall charger. So got my SIM card with the same phone number and all, and obviously, while still being my number, it had my dads apps, messages, contacts and photos on it. So I bring it home, and plug it into my computer, I cancel the intial sync, and right click on the phone on the left side of iTunes and hit "restore from backup" I look through the list of backups, and the most recent one I see is from Dec 11, 2011. Which is surprsing because i'm pretty sure I had backed up since then, but I say whatever i'll still get contacts apps and most pictures back etc. So I hit it, and go through with it, and it tells me there was a more recent date of backing up, relieved, I click on that and continue, the normal bar comes up it says something like estimated time 30 minutes, so I walk away, come back 5 minutes later, and I get an error message saying, "iTunes could not restore the iPhone "____'s iPhone" because the backup was corrupt or is not compatible with the iPhone." Confused, I go back and try again, however this time I click on "old backup (the dec 11th one rather than the newer one) and the same thing happens after a few minutes. I go back a third time, and select a time from August of 2011. And I hit restore, and it goes through. However, this happened to be a backup I made right when I got my new iPhone 4, and therefore I basically restored my phone, to having nothing. Thats where I sit right now, with none of my contacts or pictures. I'm not sure if I backed up to iCloud or not and i'm not sure how to retrieve that. Some extra things: When I try to sync my iTunes library and apps onto the new iphone 3, I need to greatly reduce the number of songs and apps beacuse this iPhone is only an 8gb while the old one was 16, (I don't think that is the reason I am getting the error message though because when I sync it clearly says "Your iPhone does not have enough space). Also, this is obviously an iPhone 3, not an iPhone 4, updated with the most recent iTunes software, which, I believe is 5.1.
Any help would be greatly appreciated as I have over 1,400 pictures saved on my old phone (very important things to me) and a contact list of over 300 including important friends, coaches, teachers and workers.
Thank you very much, if it doesn't say my email on here try me at [email protected]
Thanks again
-Drew
Edit: The current phone is an iPhone 3G, not a 3Gs.

ashleyfrg2,
you will need to restore your phone as a new device and NOT from backup. If you've been using your phone as recommended, you should have minimal data loss: Photos should have been imported to your computer right after taking them; contacts should be safe in a cloud service or on your computer. You CANNOT downgrade to 4.3.3.

HT4972 After upgrading iPhone 4 to iOS 5.1.1 getting the error "iTunes could not restore the iPhone because the backup was corrupt or not compatible with the iPhone that is being restored" HELP!

I attempted to upgrade my iPhone 4 to iOS 5.1.1. I selected 'back up' from the phone in the device menu and iTunes confirmed that the phone had been backed up. I then installed iOS 5.1.1 which wiped everything on the phone & now I am getting the error "iTunes could not restore the iPhone because the backup was corrupt or not compatible with the iPhone that is being restored".
I have tried restoring factory settings but iTunes simply will not restore from back up & I'm not sure what else to do!
Any advice would be much appreciated.

I have the same issue and I KNOW my backup IS good. What happen is when you try to restore your phone apple says something like can I check for new updates and if you choose no, it just takes you back to the restore screen and a loop from then on. If you dont update from you phone then when you back up you will have the 5.0.1 back up and then when you update to 5.1.1 and then try to restore the backup from 5.0.1 it say it EITHER corrupt or incompatible.. It is incompatible and its hard as **** to restore back to 5.0.1. I followed the restore to a T and still getting errors. I lost all text history and have to reset up email. All just because I wanted a 1.2 Gigs of "other" space back.

The iPod could not be updated because the firmware file was corrupt.

So i kept having this problem in this thread here: http://discussions.apple.com/thread.jspa?threadID=1226490&tstart=255
I decided that maybe doing a Restore on my iPod would maybe sort it out however i got that message "The iPod could not be updated because the firmware file was corrupt." when trying to restore. I then searched apple and found out that deleting the 'iPod Software Updates' folder would sort it out, it didn't.
Now what's happening is when i try to restore it comes up saying i have to download this iPod Software 1.2.1 for iPod so it downloads and then when it's finished i'm still getting the error message saying the firmware file is corrupt.
What can i do now? any help appreciated please.

this article actually sorted this problem out for me: http://docs.info.apple.com/article.html?artnum=304996
just to let you know
