Recovery Oracle 10g XE after disk crash

Hi!
I am trying to recover 10g XE database for my colleague and experiencing some problems that I cannot resolve.
He had mayor overheating problem and disk crash due to the failure of air conditioning.
OS: Windows Server 2003
DB Version: 10.2.0.1.0
After disk crashed I've managed to save image of Oracle data files and tried to recover database using them.
Database was not running in archive log mode so all files that I had were database files, control file, parameter file and redo logs.
First error that I experienced on newly installation of Oracle Express Edition (10.2.0.1.0) was:
SQL> startup
ORACLE instance started.
Total System Global Area 188743680 bytes
Fixed Size 1286460 bytes
Variable Size 62918340 bytes
Database Buffers 121634816 bytes
Redo Buffers 2904064 bytes
ORA-00227: corrupt block detected in control file: (block 16, # blocks 1)
ORA-00202: control file: 'C:\ORACLEXE\ORADATA\XE\CONTROL.DBF'
By default Oracle XE creates just one control file so I had just one incarnation of control file and apparently that file was corrupted so I tried to recreate control file.
With "ALTER DATABASE BACKUP CONTROLFILE TO TRACE" I've created script for new control file but after script execution received error.
SQL> @c:\ctlfile.sql
ORACLE instance started.

CREATE CONTROLFILE REUSE DATABASE "XE" NORESETLOGS NOARCHIVELOG
ERROR at line 1:
ORA-01503: CREATE CONTROLFILE failed
ORA-01161: database name \E in file header does not match given name of XE
ORA-01110: data file 4: 'C:\ORACLEXE\ORADATA\XE\USERS.DBF'
I also tried to use:
"CREATE CONTROLFILE SET DATABASE "XE" RESETLOGS NOARCHIVELOG..." in script but received the same errors.
Apparently database name is wrongly written in header of USERS.DBF and I don't know how to overcome this problem. Possible character set problem or data file corruption...
I used "CHARACTER SET AL32UTF8" character set.
I don't have any RMAN backups because all tapes were destroyed along with tape drive due to the air conditioning failure what caused overheating of small server room.
So if you have any idea how to open database I would be grateful for help.
Thanks!

Unfortunately this Metalink note is not solution to my problem.
My problem is database name written in the file header which is - "\E":
ORA-01161: database name \E in file header does not match given name of XE
It is obvious that database name stated in control file is not "\E" and because of that create control file script fails.
I don't know is data file corrupted and because of that I have in file header "\E", or this is some problem due to the character set, or XE Oracle software version, or something like that.
Anyway thanks for your help!
Regards,
Marko

System recovery from time machine after disk crash

Hi there,
recently I am a little unluky with my backup strategy. Here is my latest issue - I am glad if anyone has hints or advice.
On my macbook pro (mid 2009, originally SL) updated till the latest version of Mavericks I recently had a hard disc crash. I replaced the hard drive and wanted to restore my system (and data) from my time machine backup. This Backup is encrypted (in case this gives a hint for something).
What I did is I insert the Snow leopard disk, boot from it and first formated the new HD to the suggested standard for intel based MACs and then chose the option to restore from a time machine backup. I found the time capsule, connected with password, found the backed up files with date and tried to install.
First attemp failed.
Second attemp succed after 10h
Then with the mandatory reboot the system didn't start but stopped with:
panic(cpu 1 caller...
So I decided to install the SL system and try to restore from there in whatever way. Did that and 1 hour later the installation was successfully - Reboot - and then the computer asked for my Log in data (with my Log in Name - which I so far did not set on this installation or on this disk - very suprised. More suprised my password (which I use for 4 years now) did not work.
so back to option 1 try to restore from Time machine.
Ahead of that I reset the PRAM . Now I choose a backup version of an earlier date. This time the installation couldn't be finished but I got the log file.
I couldn't attach the file and didn't want to post it over severl pages...(is there a good way for that, only found adding pictures?)
Well - that's where I am stuck...
Any help is apreciated very much.

Thank you Eric for your fast answer.
this worked and now I have a running SL system. I guess I try to install maverics first and then use the emigration assistent to recover my data.
Still its a pitty that the time machine backup didn't do what it was supposed to. The workarround is very timeconsuming and leaves some concerns about my data and the future safety of time machine backups.

New HD after disk crash : how restore original partitioning scheme

Hello, After a mechanical disk crash, american version, I have to replace the hard drive of a X220, american version. Windows 7 Pro was in English.I have two VHD files backup to an external drive, as well as a repair disk.One VHD file is 348 MB and one 199 GB.I could check that the second one contains Windows 7 with software and user files.I assume that the first VHD file is the EFI partition. Because of the mechanical failure there is of course no "recovery partition".I do have a CD of Windows 7 Pro in French if required, but I assume the VHD files should suffice. My question is : how to restore the original partitioning sheme?Which is the size of partitions in bytes and in which order are they? Can someone post the output the partition table (for instance Linux's "gdisk -l" from a bootable CD or USB key) for an X220 ? Thanks a lot.

Pete291 I am showing a Photoshop CS6 full version serial number for Windows under your account at http://www.adobe.com/. Please make sure you are utilizing the serial number which ends with 94. You can find more details on how to locate your serial number at Find your serial number quickly - http://helpx.adobe.com/x-productkb/global/find-serial-number.html.
If you are using the serial number registered under your account then you can please provide additional details. Why are you reinstalling Photoshop CS6? Did you restore/migrate/transfer/copy files previously to this installation?

Reconnect to existing Time Machine after disk crash?

Hi guys!
My GF's MBP disk crashed a few days ago.
We've been backing it up to a NAS for the last few months.
Now, after replacing the disk and reinstalling OSX Mavericks, we want to make Time Machine use the old sparsebundle as it's backup target.
You know, pick up where it left and so on.
Problem is we dont know how to do that.
The Time Machine prefs seems to only want to let us choose the VOLUME - not a particular existing archive.
Isn't this possible?
Honestly, it would be surprisingly impractical if it isn't.
Thank you for constructive replies!
Cheers;
Eivind

How to restore sys after disk crash

Have HP Pavillion dv9500 laptop with Vista Op System. I had disk crash. Not recoverable. No recovery disks. I have ordered a refurbished exact same disk drive 120GB. How do I reload operating system onto refurbished disk and get system operable? I have a windows 7 home op system disk and license. Can I install the windows 7 or do I have to find a vista op system? What are the steps required to make laptop operable again?
Thanks.

Hi,
I don't know the damage of the old HDD therefore can't not say much. Now you've got new HDD, new OS (Windows 7 disc), my suggestion: install Windows 7 to new HDD from scratch and work out how to recover data/files on the old HDD. If no physical damage, you can recover data from it then use it as an external HDD such as put it in an enclosure.
Happy New Year.

[Solaris] rebooting in installing Oracle 10g R2 after Clusterware install

Hi..
Currently I am practicing the configuration of Oracle 10g R2 RAC (Solaris x86-64) with a Clusterware 10g on VMware
With the installation of Oracle Clusterware 10g software, there's no problem and look like working well on both nodes.
But, whenever I try installing the Oracle 10g R2 with 'install the software only' option, I got unstoppable rebooting
problem on the first node, rac1.
I tried both installation mode: OUI-typed and Silent approaches. Nothing worked!!
I wanted to figure out why this problem happened, but so far I did not have any bright answer for this. I looked in
the log and error files from /u01/app/oracle/oraInventory/logs, but there's no good answer or hint to resolve the
problem I have now.
Until now I tried 4 times of installations, but all stopped and were automatically rebooted at the same point with
almost 3% copying of software. I found some of trainers are having same problem I have now.
oracle@rac1 ~ $ crs_stat -t
Name           Type           Target    State     Host
ora.rac1.gsd   application    ONLINE    ONLINE    rac1
ora.rac1.ons   application    ONLINE    ONLINE    rac1
ora.rac1.vip   application    ONLINE    ONLINE    rac1
ora.rac2.gsd   application    ONLINE    ONLINE    rac2
ora.rac2.ons   application    ONLINE    ONLINE    rac2
ora.rac2.vip   application    ONLINE    ONLINE    rac2
This happens whenever I install the Oracle 10g R2 software.
Is there any unknown or hidden problem regarding CRS or something else?
Anybody has some hints or solution to this problem? If so, please let me have it ASAP.
Thank you so much.

I have gone through similar problem when installing oracle 10g in linux. You should follow the oracle installation documentation and make sure that all required OS patches and packages must be installed before starting the oracle installation. In my installation few OS packages was missing in the oracle documentation too and searching over the net solved the problem. I have installed few extra OS packages (RPM) and installed oracle successfully.

Problems restoring Backup after disk crash & exchange

Recently, the harddisk in my iBook started acting up and eventually died. I had made a backup three days prior to the crash, so I still have (most of) my data.
I brought my iBook to an Apple repair shop, where they mounted a new hard disk. So far so good.
Unfortunately, I've been trying to put my backup on the new disk for the last five days, without succes.
At first I thought it might have had to do with the diskimage I had, like "unreadable" names, but even after rewriting the image to a read/write one, and deleting or renaming the files that had unfortunate signs in it, I still keep getting an error, namely
" An error (2) occurred while copying. (No such file or directory) "
I can't find what's going wrong, I tried everything I could come up with - even simply extracting the files to the disk, but this of course skips most of the hidden files; and when doing this from within the terminal, I still get "Permission denied" errors...
If anyone could help me on this one, I'd be very grateful!
Ah yes, the backup is on an external FW disk, from which I can also boot - which is what I'm doing right now as well; so it's not that I can't write to the disk because it's busy as the bootdisk.

*\mood happy*
Booting still failed this morning... So I thought I'd delete some files from the image to make it copy faster...
I tried Silver Keeper again (when choosing a source, it asks whether one wants the destination to become bootable); and this time - it worked.
I have CCC as well, but haven't tried it.
Anyway - the disk has now been restored and is bootable, so I'm happy. I'll still have to copy back a few directories (the ones I deleted, together around 40gigs, homemade pictures and movies... Not really necessary for a diskrestore at first, I figured), but it works now.
Thank you again; for helping me, but also for teaching me (indirectly as well) a few things about the Mac filesystem.
*end of report with a successful recovery*

Reinstall Itunes after disk crash

Hi folks
Maybe a simple question for You, but not for me :o)
Three weeks ago the disk on my HP Pavilion DV8 crashed. The operatingsystem is Windows 7.
Today I received y HP with a new harddisk, and a new Windows 7 installation.
After having installed a lot of programs, I also install Itunes.
But what will happen the first time i connect my Iphone 3GS?
Will al data on the phone (contacts, calendar data, applications and so on) be delete on the Iphone?
What to do to save all I have?
Best regards
Carsten

You need to copy everything from your backup copy of the old computer to the new one.
When you sync the itunes content ( apps/music/vid) will be erased and replaced with content from the new computer.
If you sync contacts and calendars to a blank computer, then those will be erased as well.
One of the many reason that always maintaining a backup copy is so basic, is the very situation.
Use your backup to put everything on the new computer.

Recovering drivers after disk crash

My hard drive crashed. Fortunately I had a current Time Machine backup which restored all my files. I thought. I had no exclusions in the Time Machine options, so I am sure I did not exclude my drivers, but somehow, they did not restore. I am speaking specifically of my printer and camera drivers, but there may be others I have not discovered. And for some reason, I am unable to reinstall them from the original manufacturer's web site. The Canon camera drivers apparently install, but no luck in iPhoto, it doesn't see the camera. The Brother 5250 drivers are a different matter. For some reason I need to know IP addresses, DNS server names and other stuff to get the driver I downloaded to work. Don't know how and don't know why. It worked before using Snow Leopard.
My question is this, assuming I get my drivers reinstalled somehow (although all suggestions would be welcome), how can I ensure that they get backed up and restored if the crash ever happens again?

The Apple fix-it folks replaced the disk and installed Snow Leopard. From that point on, I did a full system restore, including using the Snow Leopard disk. I have been using the computer for a few weeks now, so I can't imagine redoing a full system restore makes sense any more.
Oh, no, if it didn't restore that way the first time, it won't now.
Where are the drivers for printers kept anyway? I am not familiar with the Mac system libraries. Maybe I can just find the driver on a really old back up somewhere, or on my other Mac, which has the same drivers, and just copy them over?
Most of the printer stuff seems to be in the maker's folder inside the top-level /Library/Printers folder.
It's very odd that they didn't restore. I don't recall ever seeing that reported here.
You might also want to browse, search, or re-post in the +Printing, Faxing, and Scanning+ forum. There's likely someone there with better info.

Reinstal after disk crashed

After my secondary hard drive crashed I cant install itunes anymore on my new hard drive since the old installation blocks this. How do I solve this?
Itunes was installed on my secondary hard drive and now that I got a new secondary hard drive my old installation seems to block the installement of Itunes on my new drive. I think there are some system registers that still link to the old drive since I get a message saying that "the path to programfiles (x86) contains a invalid character"* I never get to choose where to instal though so I think itunes still has a key somewhere in windows that links to the old location. My knowledge of computers only goes this far though, I have no clue how to find these keys and or change/delete them.
I would apreciate any help

Can not restore all data/files after disk crash.

I have a intel MacBook Pro (2008). Hard drive crashed. I replaced the drive and all is well with that. I re-installed Leopard and the Snow Leopard upgrade. Now I am trying to restore all my files/data from my external LaCie drive. All I am seeing is it says "copying to volumes". I don't see the files or anything on my new drive. What am I doing wrong??

Not sure, but here is a link that may help:

Xfer voice memos after disk crash on syncd pc

Can anyone out there tell me how to get large (~40 minute) voice memos off an iphone without syncing?
Or - how to sync to a new itunes instance without deleting all the content on the iphone?
The old PC that the iphone was sync'd with .. crashed and died.
Meanwhile my beloved continued to add lengthy voice memos to the iphone.
I cannot now get those much desired voice memos off the iphone to a new itunes install on a different computer even though it is authorized under same ID. The sync operation threatens to erase everything on the iphone.
IOS is not up to date; it is 3x, I think (beloved has iphone on an airplane somewhere over the midwest at this moment so I can't look).

Restoring iCal calendars after disk crash

OK, I haven't found this on any discussions I've read so far.
My disk died on my MacBook Pro on Wednesday. It's in the shop. Fortunately I had backed it up on the Saturday before. Now I am temporarily using my iMac. Both are (were) on Leopard.
My question is - what did Apple do to the calendar files!? Through Tiger, calendar files were .ics files, and they corresponded directly to my different calendars by name. When I went to Library/Calendars, some of those were there, but they were ones from long ago. However, there were all these .calendar folders there with an Event folder and a file called info.plist in each of them.
In the Events folders for all these are files named, for example, 00C6C072-2C48-4B99-B3A2-B3241655578A.ics, and these .ics files are the only ones iCal seems to want to import. But when I import them, they are single events, as far as I can tell and the name of the "calendar" in my Calendars list in iCal is, for example, 00C6C072-2C48-4B99-B3A2-B3241655578A. This, of course, isn't at all helpful in trying to restore old calendars - or new ones - by importing them. So, it seems to me that Import is useless in this situation or any other.
Has anyone got any info that can help me understand what they've done here and why (well, no one probably wants to know why), and how I get my calendars back?
Hopefully the tech fixing my MacBook Pro will be able to recover some data from the disk drive, and the old calendars will be among the data recovered, but even then, with this new system of saving calendars and events, how does one import calendars into the newly installed iCal?
I'm not looking forward to having to rebuild my calendars, but it's looking as if I may have to. So far, this design of iCal is not a better idea.
Thanks in advance for any help anyone can give me.

Well I finally solved the problem. The confusion is in the wording.
Both iCal and Address Book have functions that work well to move calendars and contacts from one machine to the other.
Menu\File\Back up Database.
Menu\File\Revert to Database Backup.
Well I was scared of the Revert to Database Backup. It works. When you do so, you just point the program to the backup that you just made from the other machine, if it's what you are trying to accomplish.
I hope this might help you.
Maybe everybody knows how to do this and I am a slow brain - Leon.
