hello gurus,

       1 - I did a save cold datafile.

       2 - i restored my datafiles but i losed the redo file.

       3 - First question : is it possible to start my database without the redolog.

             then :

             3-1 - > startup mount

             3-2 - > alter database open: then normal because i losed my redolog

             3-3 - > alter database open

                         ERREUR Ó la ligne 1 :
