How to recover data if a data file has been lost
If I have a tablespace with 5 9i or 10g data files...It's a fictitious scenario :)
one was lost when starting db
and other 4 remained thre
If no backups available for no archivelog to recreate the data and restore file
How do I in this tablesapce of data recovery?
Thanks in advance!

If you
a. Partition Table
b. put each Partition in a separate space
c. for datafile (s) of each storage space, use a separate disk (or set of disks) such that no two storage spaces are on the same disk
...
You then able to reach the level of "fault tolerance" - may be because the data file will also drive goes wrong (and two data files or storage on the same disk goes wrong makes life difficult!)
except that... your question was an exercise. Only that you have changed the rules in between!

1)
SQL > startup nomount
SQL > execute script

sqL. ALTER database open resetlogs;Note: datafile header SNA will be stamped to controlfile one
If no backup of the file available trace control, then perform the Ridge below the action plan
Any other database

I would like to know if it is possible to delete all the data that has been downloaded by this text file.
Thank youHello
Just do the same combination in excel add in or smart view and change the value to #Missing and send it.
The other way is that you can write a script for the same and use CLEARDATA inside.
Please see the link - http://docs.oracle.com/cd/E12825_01/epm.111/esb_dbag/frameset.htm?dcadevcs.htmHope this helps

How can I recover the DB to its original state.
Please update... This is essential for us...
Thanks in advance...If you want to get rid of this message and must implement the database without this data file;
ALTER database datafile ' / proddata/testdata/ts_test01.dbf' offiline.
ALTER DATABASE DATAFILE
DROP offline
or
ALTER DATABASE DATAFILEoffline drop offline must not be used unless you know what you're doing...
the other is "safe". You can online again.

Restore a data file has been added
So here is the situation that I am:
A customer has a backup from August 1, 2010 with all archivelogs since then until now. They need restore such backup to another server, but a data file was added to the database, August 8 and no database backup was taken, but there is an automatic backup of the controlfile. If I can restore to the other server with what I have?
I thought up the database using the controlfile autobackup on August 8, and then restore and recovery, but who could make me ' backup of the data file x not found ' errors?
Or can I do a simple restore and recover with the backup on 1 August and just apply all archivelogs as usual?
Any help would be appreciated. Thank you
-Oracle 10 g 2 SE on Linux btwHi oscrub,
If I can restore to the other server with what I have?
Yes, either controlfile it doesn't matter.
that could make me ' backup of the data file x not found ' errors?
No, not in 10g, during the recovery of the file is recreated by oracle.
(BTW this won't work for ordering duplicate rman 10 g)Or can I do a simple restore and recover with the backup on 1 August and just apply all archivelogs as usual?
This will work as well.
Kind regards

While tyring to download a frm file held in d-drive pict, there, he was misplaced.pl advise how to trace it.
There are a few things you can try:
- Try right click on an empty spot in any folder and see if "Undo Move" is an option. It would help if you accidentally dragged the folder to another and moved inadvertently.
- Try to open the computer in your Start menu and type in the search box, some of a file name, that you remember this folder. It will search all your computer (and readers) for the file name. If it is found, you can right click and choose "Open containing folder" to know where he is and bring it back to its proper location.

How to restore a file that has been lost and partially restored?
I have it has not deleted, but when I started my computer a scan of indexing was performed for a deleted file. What was restored was an older version of the deleted file. There were parts of other files deleted also. Or old version have been restored instead of the current version.
I have it has not deleted, but when I started my computer a scan of indexing was performed for a deleted file. What was restored was an older version of the deleted file. There were parts of other files deleted also. Or old version have been restored instead of the current version.
It should be a little clearer, at least for me.
What do you mean by "a scan of indexing was performed?
What do you mean by "shares of other files deleted also?
How the file was restored?
Do you mean that you have run a chkdsk and it detected disk errors and attempted to remedy and that you are now looking to the files created by chkdsk (*.chk files)?
The computer is configured to automatically perform a disk check. He said this morning it was running a check disk and restore one of my files. This file has been restored to a version much sooner, as well as several other files when I checked later. I ran a check of the index that says he would restore the files, but that did not help. It will only run chkdsk. I think I'll have my paid gurus do. Thanks for your help.
