hi
When I restore controlfile from autobackup
and than restore database and recover database;
I can only open the database with openresetlogs option.
why?

but I can apply archivelogs, that is created after the old controlfile.why force to open resetlogs?

CONTROLFILE contains "current" SCN; & therefore are "obsolete" after the next transaction after being backed up.

In order to open the database the SCN in the datafiles must match the SCN in the control files.
