No. The control file has the current state of the database. It will consider the database up to date if all the scn's match.
You could fool the database into rolling forward with a more recent copy of the control file (say at the time of crash), but if you are recovering with an old version of the control file (at the time of the day-old backup) you can't make Oracle apply archive logs that are newer, and have newer SCN's, to the database. did I explain that clearly?
Ron, try it sometime. Recovering with a more recent control file is kinda slick :)

I know, but the point is Oracle doesn't know anything about the archive
logs, it just takes whatever you feed it until you cancel.
Correct?

As long as you have all archived log files in log archive destination
directory, which is defined in init.ora, you don't have to do anything but
type 'auto' while doing recovery. Oracle will automatically apply all
necessary archive log files and then you need to open database.

I have a "what if" question.
Say you had a complete cold backup, including control files from a few days
ago.
You also had all the archive logs for the past few days.
Today you lost your server and had to recover.
You lay down all the database files, including the control files.
Now you want to apply your archive logs.
Oracle can't know about the archive logs because all the files you restored
are old.
Do you just tell Oracle where the archive logs are and it keeps aplying them
until
you say you are finished?
Just wondering.
