Dana,
The database will spit errors. I found as long as you are only reading data and not trying any DDL or stuff like that, for the most part the database will continue to run. As the DBA, if you rush in and copy one of the control files over to where the missing one was, the database will continue running. Remember, no changes will be allowed that will write to the control files - this will fail because Oracle wants to write to every one of them, and if one is missing, nothing gets changed.
This helps if you can't just bring down your database (like me).
I tested this a couple of weeks ago.

Subject: 1/2 control file failure - will database halt?
I've been told a single control file failure will halt
the database, even if you've got another control file on
a second device; that the database will only come up again
after editing the init.ora to remove the reference to the
faulty control file and initiating a fresh startup.
Is this still true, if it ever was true for any version of Oracle, for
Oracle 8.X+? The person who warned me about the halt has been using
Oracle since version 5.
Thanks very much.
- Dana
