so, do the control files exist? What did you do before you got this
error message? Restore database/controlfiles? if they exist, are
they the correct controlfiles and does they have the correct ownership/
permissions?

Do the control files exists in that location?

Cause: The system could not find a control file of the specified name
and size.

Action: One of the following:

Check that the proper control file name is referenced in the
CONTROL_FILES initialization parameter in the initialization parameter
file and try again.

When using mirrored control files, that is, more than one control file
is referenced in the initialization parameter file, remove the control
file name listed in the message from the initialization parameter file
and restart the instance. If the message does not recur, remove the
problem control file from the initialization parameter file and create
another copy of the control file with a new file name in the
initialization parameter file.
