When I try to startup my database, I get this error:

"ORA-00205 error in identifying controlfiles, check alert log for more details"

I had 3 control files in my parameter file and for debugging purposes, tried with each one but I'm getting the same error.

What should I do now??? I found from a book that the only solution if all the control files are corrupted, is to use this command:

"alter database backup controlfile to trace;"

and to get the proper "create controlfile" command and then to use it.

But, as I didn't understand this properly, wanted to clarify with u guys..

Could you please help me out.. Thanks in advance..
