RE: Database recovery problem

From: Onkarnath Tiwari <>

I had not deleted the system files but after seeking for ur help , I had been suggested by one of my colleague to try to recover the database using the backup of controlfile. The steps were :

  1. after the user deleted the datafiles, I took the backup of controlfile to trace.
  2. then issue the command recover database using backup of controlfile until cancel and after that it was giving this error. But just to mention that I had not dropped the system files.

After ur suggestion I had issued the command alter database datafile '<<name>>' offline drop; then repeated the steps once again and supplied the redo log file name with the path and the database got opened. However I had intimated the owner team of the database to take the backup regularly and put it in archivelog mode so that recovery of the data could also be possible.

Thanks a million once again for ur help and co-operation

Thanks & Regards,

Why did you drop the system file? Did this file get deleted also? If so, then you are all done. You cannot open the database if the system file is gone.

Your prior email only mentioned the
D:\DB\ORADATA\BODEV\NMSANDBOX_DATA.ORA file. Michael's and my response would work fine if only a data file was deleted. But if the system file is gone, then call it a day. Your database is gone.

ERROR at line 1:
ORA-01589: must use RESETLOGS or NORESETLOGS option for database open

ERROR at line 1:
ORA-01152: file 1 was not restored from a sufficiently old backup ORA-01110: data file 1: 'F:\ORACLE\ORADATA\BODEV\SYSTEM01.DBF'

This is what I got after putting this file in offline drop mode. Now what???? By the way in the mean time after the suggestion of one of my colleage I had issued one command i.e.
Recover database using backup controlfile until cancel;

Is this command did something wrong???

almost correct
startup mount;
alter database datafile 'D:\DB\ORADATA\BODEV\NMSANDBOX_DATA.ORA' offline drop;
alter database open;
if the database still wants to recover more files you need to drop them also, if it wants to recover system it's time to learn irish say
faster and faster with an bit of an irish lilt. back to the problem at hand.
drop tablespace tablespace_of_the_above_datafile; then reload your data because you were in noarchivelog mode so you must be
able to reload your data.

then take this opportunity to crank up your buffer cache to as big as possible -- this is a joke, no flames please.


It is asking for an archive file because the dummy file that you created is
not an Oracle database file. So it is trying to bring it up to date. Even
though you are not running in archivelog mode, Oracle still acts the same
way - that is, it is keeping track of what would be the correct archivelog
file even though it did not write them out to disk.

You have one option:

Startup mount;
Alter datafile 'D:\DB\ORADATA\BODEV\NMSANDBOX_DATA.ORA' offline. Alter database open.

You will be able to export all of the data in the database except what was
stored in this data file. This will allow you to import it into another database.

So all of your data is not gone - just the stuff in this file/tablespace.
Everything else has been lost.

Good Luck!

hi all,

We have got one oracle 9i rel 2 on windows 2000 running in no-archive log
mode. the problem is one of the dba of the other team has deleted some of
the dbf files while the database was running and tablespace was online. after deleting the file he re-started the database which while opening throw
error saying that file needs recovery. I was told to do this . I have created the dbf files also but while recovering the dbfs using RECOVER DATAFILE ' 'D:\DB\ORADATA\BODEV\NMSANDBOX_DATA.ORA'; command its asking for
the archive files . output is below mentioned :

SQL> recover datafile 'D:\DB\ORADATA\BODEV\NMSANDBOX_DATA.ORA'; ORA-00279: change 38062424 generated at 05/13/2005 00:52:05 needed for thread 1
ORA-00289: suggestion : F:\ORACLE\ORA92\RDBMS\ARC00397.001 ORA-00280: change 38062424 for thread 1 is in sequence #397

Specify log: {<RET>=suggested | filename | AUTO | CANCEL} I dont know why its asking for the archive files.??? Btw the team who is owning the database has not taken any backup. If anyone has got the problem
like this , plz. share ur experience so that I can perform this.
