Hi,

I was trying to upgrade from oracle 9i to 10g.Everything was going fine until I made a big mistake.I have deleted the DATAFILE manually from the disk and now when I try to do anything I'm experiencing errors.
Below are the errors and the datafile details ::

C:\Documents and Settings\devadm>sqlplus "/as sysdba"

this is the datafile I have manually deleted :
"ORA-01110: data file 24: 'D:\ORACLE\DEV\SAPDATA1SYSTEM.DATA2'"

Now I dont understand what could be done to make this working so that my upgrade to 10g is not interrupted.

Is there any process to again create the datafile of same name and proceed further.I have also tried to do it through sql but i get the same errors and was not able to do anything

please help

I hope you have good backups & know how to successfully restore the database.

Doesn't matter.

Your DATA is gone.

The only two options left are :

- Restore the data from backup OR
- Delete the database and create a new one.

You can't continue the upgrade process from the point you are stuck now.

as it is the system tablespace datafile which was deleted im in trouble...is it possible to create the system tablespace again by deleting the current system tablespace?

Also I have a small trick currently developing in my mind.
can a system tablespace datafile with the same name created on a different computer and then copied to this computer at the exactly same location from where the database file was created???

may be with other technologies. Not with Oracle.
I just cannot digest that you were upgrading without a backup.
Did you try your luck with windows recycle bin? Or did you wipe it real clean?
