alert.log !Warning message

[gnagesh]

Hi

I have following message in my alert.log. This is caused when i recover database until cancel using backup controlfile . The recovery was success. Database opened without any problem. Backup was COLD BACKUP.

WARNING! Recovering data file 1 from a fuzzy file. If not the current file
it might be an online backup taken without entering the begin backup command.

The above warning message was returned for all of my datafiles.

Any ideas..

Thanks in Advance.

The fuzzy backup message means that the file is in an incomplete state.
This happened because you issued a hot backup and the ALTER TABLESPACE %s END BACKUP command was executed before the copy command finished.

If you are using HOT backup mode, use the ocopy.exe command on windows (it allows copy of open files).

cheers.
