So you
don't bring the DB down and then copy the controlfile? You just copy
it? Just curious

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.

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.
